  • Implicit process interventions in eating behaviour: A meta-analysis examining mediators and moderators
    Health Psychol. Rev. (IF 8.597) Pub Date : 2019-01-24
    Matthias B. Aulbach, Keegan Knittle, Ari Haukkala

    Dual-process models integrate deliberative and impulsive mental systems and predict dietary behaviours better than deliberative processes alone. Computerized tasks such as the Go/No-Go, Stop-Signal, Approach-Avoidance, and Evaluative Conditioning have been used as interventions to directly alter implicit biases. This meta-analysis examines the effects of these tasks on dietary behaviours, explores potential moderators of effectiveness, and examines implicit bias change as a proposed mechanism.

  • Challenges and solutions for N-of-1 design studies in health psychology.

    Theories of behaviour change and health behaviour change interventions are most often evaluated in between-person designs. However, behaviour change theories apply to individuals not groups and behavioural interventions ultimately aim to achieve within-person rather than between-group change. Within-person methodology, such as N-of-1 (also known as single case design), can circumvent this issue, though has multiple design-specific challenges. This paper provides a conceptual review of the challenges and potential solutions for undertaking N-of-1 studies in health psychology. Key challenges identified include participant adherence to within-person protocols, carry-over and slow onset effects, suitability of behaviour change techniques for evaluation in N-of-1 experimental studies, optimal allocation sequencing and blinding, calculating power/sample size, and choosing the most suitable analysis approach. Key solutions include involving users in study design, employing recent technologies for unobtrusive data collection and problem solving by design. Within-person designs share common methodological requirements with conventional between-person designs but require specific methodological considerations. N-of-1 evaluation designs are appropriate for many though not all types of interventions. A greater understanding of patterns of behaviours and factors influencing behaviour change at the within-person level is required to progress health psychology into a precision science.

  • The relationship between habit and healthcare professional behaviour in clinical practice: a systematic review and meta-analysis
    Health Psychol. Rev. (IF 8.597) Pub Date : 2019-01-08

    Theories of behaviour used to understand healthcare professional behaviour often focus on the deliberative processes that drive their behaviour; however, less is known about the role that implicit processes such as habit have on healthcare professional behaviour. This systematic review aimed to critically appraise and synthesise research evidence investigating the association between habit and healthcare professional behaviour. A search of five databases (PsycINFO, EMBASE, Scopus and CINAHL) was conducted up until 29 February 2016 to identify studies reporting correlations between habit and healthcare professional behaviours. Meta-analyses were conducted to assess the overall habit-behaviour association across all behaviours. A subgroup analysis assessed whether the habit-behaviour relationship differed depending on whether the behaviour was objectively measured or assessed by self-report. We identified nine eligible studies involving 1975 healthcare professionals that included 28 habit-behaviour correlations. A combined mean r+ of 0.35 (medium effect) was observed between habit and healthcare professional behaviour. The habit-behaviour correlation was not affected by whether behaviour was measured objectively or by self-report. This review suggests that habit plays a significant role in healthcare professional behaviour. Findings may have implications for considering health professionals’ habit when promoting the provision of evidence-based health care, and for breaking existing habit when de-implementing outdated, non-evidence-based practices.

  • Control-Coping Goodness-of-Fit and Chronic Illness: A Systematic Review of the Literature
    Health Psychol. Rev. (IF 8.597) Pub Date : 2018-12-17
    Lucy Finkelstein-Fox, Crystal L. Park

    Chronic illnesses such as cancer, diabetes, and chronic pain often create intense and pervasive stress. Although much research has focused on the importance of coping in managing chronic illness, the importance of controllability appraisals in determining the efficacy of various coping strategies (i.e., the ‘goodness-of-fit hypothesis;’ Lazarus & Folkman, 1984) for individuals living with chronic illness has yet to be established. To evaluate support for the goodness-of-fit hypothesis, we conducted a systematic literature review, identifying and synthesizing results of 15 studies that reported on conditional effects of problem-, emotion-, and meaning-focused coping strategies, depending on controllability appraisals. Results across studies were mixed, with some coping strategies but not others demonstrating significant interaction effects with controllability appraisals in models predicting psychological and physiological markers of health. Studies demonstrated considerable heterogeneity in design and measurement, with the majority reliant on cross-sectional design and thus unable to infer temporality in the effects of coping on adjustment. In addition, lack of consensus regarding the measurement and categorization of coping precluded definitive conclusions regarding contextual effects of many strategies. To better understand these patterns of coping as they unfold in daily experience, future work should incorporate contemporary methods such as experience sampling and multilevel statistical modeling.

  • A systematic review of patients’ drawing of illness: Implications for research using the Common Sense Model
    Health Psychol. Rev. (IF 8.597) Pub Date : 2018-12-17
    Elizabeth Broadbent, Jan W. Schoones, Jitske Tiemensma, Ad A. Kaptein

    Recent research has examined patients’ drawings of their illness as a means to identify patients’ illness representations. The aim of this systematic review was to examine which representations are evident in patients’ drawings, and whether drawing assessments are associated with patient outcomes. Ten electronic databases were searched for published journal papers in English up to July 1 2017. Narrative synthesis summarized findings by participant characteristics, study design, illness representations, and associations with outcomes. There were 101 eligible studies, published across 29 different countries, with 27 different disease categories; 54 of the studies were with adults and 80 were cross-sectional. All core illness perception domains were evident; the most common being identity and related concepts (including symptoms, anatomy, pathophysiology), and emotional representations (including fear, denial, stigma). Perceptions of treatment and the clinical and social environment were evident. More organ damage drawn and larger drawing size were associated with worse perceptions and health outcomes, and drawings distinguished between patient groups. Limitations include the inability to conduct meta-analysis. In conclusion, patients’ drawings reveal additional domains of illness representations, specifically perceptions of pathophysiology, treatment and social environments, as well as illness pre-occupation. These findings expand theories of self-regulation and suggest image-based intervention strategies.

  • Examining the active ingredients of physical activity interventions underpinned by theory versus no stated theory: A meta-analysis
    Health Psychol. Rev. (IF 8.597) Pub Date : 2018-11-09

    In this meta-analysis, we sought to examine the ‘active ingredients’ (or behavior change techniques; BCTs) used within theory-based physical activity interventions compared to interventions with no stated theory. We retrieved 171 peer-reviewed studies (224 total interventions) that used a controlled experimental design from 68 previous reviews of physical activity interventions. Data from each intervention were coded with regard to their use of theory and inclusion of 16 BCT clusters within the physical activity intervention. There were no significant differences in the overall effect sizes between theory-based (k = 148, d = 0.48) and no-stated-theory (k = 77, d = 0.37) interventions. Theory-based interventions incorporated a greater number of BCT clusters on average (6.1) compared to no-stated-theory interventions (4.5). Significant effects were shown for interventions that incorporated at least three BCT clusters (d = 0.48) but not for those that used one or two (d = 0.20). Several BCT clusters were more likely to be present in theory-based interventions than no-stated-theory interventions. Significant effects on physical activity were also shown for theory-based interventions that incorporated any of the 16 BCT clusters coded, but only for 9 out of 11 no-stated-theory interventions in this regard (for which effect sizes could be calculated). Taken together, these findings suggest that although the overall effects on physical activity do not differ significantly between theory-based and no-stated-theory interventions, these interventions often differ in their composition of BCTs. Moreover, for interventions utilizing certain BCT clusters (namely, ‘self-belief’ and ‘association’), theory may be necessary to derive significant effects.

  • A meta-analysis of techniques to promote motivation for health behaviour change from a self-determination theory perspective
    Health Psychol. Rev. (IF 8.597) Pub Date : 2018-10-08

    A systematic review and meta-analysis was conducted of the techniques used to promote psychological need satisfaction and motivation within health interventions based on self-determination theory (SDT; Ryan & Deci, 2017). Eight databases were searched from 1970-2017. Studies including a control group and reporting pre- and post-intervention ratings of SDT-related psychosocial mediators (namely perceived autonomy support, need satisfaction and motivation) with children or adults were included. Risk of bias was assessed using items from the Cochrane risk of bias tool. 2496 articles were identified of which 74 met inclusion criteria; 80% were RCTs or cluster RCTs. Techniques to promote need supportive environments were coded according to two established taxonomies (BCTv1 and MIT), and 21 SDT-specific techniques, and grouped into 18 SDT based strategies. Weighted mean effect sizes were computed using a random effects model; perceived autonomy support g = 0.84, autonomy g = 0.81, competence g = 0.63, relatedness g = 0.28, and motivation g = 0.41. One-to-one interventions resulted in greater competence satisfaction than group-based (g = 0.96 vs. 0.28), and competence satisfaction was greater for adults (g = 0.95) than children (g = 0.11). Meta-regression analysis showed that individual strategies had limited independent impact on outcomes, endorsing the suggestion that a need supportive environment requires the combination of multiple co-acting techniques.

  • Dyadic Interventions to Promote Physical Activity and Reduce Sedentary Behaviour: Systematic Review and Meta-Analysis

    R.M. Carr, A. Prestwich, D. Kwasnicka, C. Thøgersen-Ntoumani, D.F. Gucciardi, E. Quested, L.H. Hall, N. Ntoumanis

    Several interventions have targeted dyads to promote physical activity (PA) or reduce sedentary behaviour (SB), but the evidence has not been synthesised. Sixty-nine studies were identified from MEDLINE, PsycINFO, and Web of Science, and 59 were included in the main meta-analyses (providing 72 independent tests). Intervention details, type of dyadic goal, participant characteristics, and methodological quality were extracted and their impact on the overall effect size was examined. Sensitivity analyses tested effect robustness to (a) the effects of other statistically significant moderators; (b) outliers; (c) data included for participants who were not the main target of the intervention. Dyadic interventions had a small positive, highly heterogeneous, effect on PA g = .203, 95% CI [0.123–0.282], compared to comparison conditions including equivalent interventions targeting individuals. Shared target-oriented goals (where both dyad members hold the same PA goal for the main target of the intervention) and peer/friend dyads were associated with larger effect sizes across most analyses. Dyadic interventions produced a small homogeneous reduction in SB. Given dyadic interventions promote PA over-and-above equivalent interventions targeting individuals, these interventions should be more widespread. However, moderating factors such as the types of PA goal and dyad need to be considered to maximise effects.

  • Experimental Manipulation of Affective Judgments about Physical Activity: A Systematic Review and Meta-Analysis of Adults

    Ryan E. Rhodes PhD, Samantha M. Gray MSc, Cassandra Husband MSc

    Affective judgments (AJ; i.e., thoughts about the overall pleasure/displeasure, enjoyment, and feeling states expected from enacting a behavior) have been linked reliably to physical activity (PA) in observational research and feature in various theoretical frameworks. The purpose of this meta-analysis was to examine the current effectiveness of interventions to change AJ and subsequent PA behavior and explore potential moderators. Eligible studies were published in a peer-reviewed journal in the English language, included an experimental design in the PA domain with a measure of AJ as the dependent variable, and were conducted with an adult (>17 yrs.) sample. Literature searches concluded in July 2017 using 11common data-bases, with additional hand searching conducted in February 2018. The search yielded 32 independent studies after screening for eligibility criteria. Results using random-effects meta-analysis showed positive changes in AJ favoring intervention over control groups g = 0.43 (95% CI = 0.26–0.60). These changes predicted (β = 0.64) positive changes in PA g = 0.38 (95% CI = 0.16–0.60) among a sub-sample (k = 14) of studies that also provided behavioral data. Moderator analyses showed the effects were inflated by potential publication bias, participant gender (females had higher AJ than mixed samples), baseline PA (larger effects for inactive samples) and focus of the intervention (larger effects when AJ was the primary focus), but specific behavior change techniques were inconclusive. AJ may show change from experimental intervention and meaningful links to behavior change but larger sample studies are required to obtain a more reliable effect size estimate. Further, few studies have employed behavior change techniques that would align with the theoretical reasons for changes in AJ so our evidence for practical intervention content is limited.

  • Can You Elaborate on That? Addressing Participants’ Need for Cognition in Computer-Tailored Health Behavior Interventions
    Health Psychol. Rev. (IF 8.597) Pub Date : 2018-09-16

    Computer-tailored interventions, which deliver health messages adjusted based on characteristics of the message recipient, can effectively improve a range of health behaviors. Typically, the content of the message is tailored to user demographics, health behaviors and social cognitive factors (e.g., intentions, attitudes, self-efficacy, perceived social support) to increase message relevance, and thus the extent to which the message is read, considered and translated into attitude and behavior change. Some researchers have suggested that the efficacy of computer-tailored interventions may be further enhanced by adapting messages to suit recipients’ need for cognition – a personality trait describing how individuals tend to process information. However, the likely impact of doing so, especially when tailored in conjunction with other variables, requires further consideration. It is possible that intervention effects may be reduced in some circumstances due to interactions with other variables (e.g., perceived relevance) that also influence information processing. From a practical point of view, it is also necessary to consider how to optimally operationalize and measure need for cognition if it is to be a useful tailoring variable. This paper aims to facilitate further research in this area by critically examining these issues based on relevant theories and existing evidence.

  • Using the common-sense model to understand health outcomes for medically unexplained symptoms: a meta-analysis

    Consistent with the common-sense model of self-regulation, illness representations are considered the key to improving health outcomes for medically unexplained symptoms and illnesses (MUS). Which illness representations are related to outcomes and how they are related is not well understood. In response, we conducted a meta-analysis of the relationship between illness representations, self-management/coping, and health outcomes (perceived disease state, psychological distress, and quality of life) for patients with MUS. We reviewed 23 studies and found that threat-related illness representations and emotional representations were related to worse health outcomes and more negative coping (moderate to large effect). Generally, increases in negative coping mediated (with a moderate to large effect) the relationship of threat/emotional illness representations and health outcomes. Protective illness representations were related to better health outcomes, less use of negative coping and greater use of positive coping (small to moderate effect). The relationship of protective illness representations to better health outcomes was mediated by decreases in negative coping (moderate to large effect) and increases in positive coping (moderate effect). Perceiving a psychological cause to the MUS was related to more negative health outcomes (moderate to large effect) and more negative emotional coping (small effect). The relationship of perceiving a psychological cause and more negative health outcomes was mediated by increases in negative emotional coping. Improving our understanding of how illness representations impact health outcomes can inform efforts to improve treatments for MUS. Our results suggest behavioural treatments should focus on reducing threat-related illness representations and negative coping.

  • Complex adaptive systems: a new approach for understanding health practices
    Health Psychol. Rev. (IF 8.597) Pub Date : 2018-09-24
    Tim Gomersall

    This article explores the potential of complex adaptive systems (CAS) theory to inform behaviour change research. A CAS describes a collection of heterogeneous agents interacting within a particular context, adapting to each other’s actions. In practical terms, this implies that behaviour change is (1) socially and culturally situated; (2) highly sensitive to small baseline differences in individuals, groups, and intervention components; and (3) determined by multiple components interacting ‘chaotically’. Two approaches to studying CAS are briefly reviewed. Agent-based modelling is a computer simulation technique that allows researchers to investigate ‘what if’ questions in a virtual environment. Applied qualitative research techniques, on the other hand, offer a way to examine what happens when an intervention is pursued in real-time, and to identify the sorts of rules and assumptions governing social action. Although these represent very different approaches to complexity, there may be scope for mixing these methods – for example, by grounding models in insights derived from qualitative fieldwork. Finally, I will argue that the concept of CAS offers one opportunity to gain a deepened understanding of health-related practices, and to examine the social psychological processes that produce health-promoting or damaging actions.

    Studies investigating attentional biases towards pain information vary widely in both design and results. The aim of this meta-analysis was to determine the degree to which attentional biases towards pain occur when measured with the dot-probe task. A total of 2168 references were screened, resulting in a final sample of 4466 participants from 52 articles. Participants were grouped according to pain experience: chronic pain, acute pain, anticipating experimental/procedural pain, social concern for pain, or healthy people. In general, results revealed a significant, but small bias towards pain words (d = 0.136), and pain pictures (d = 0.110) in chronic pain patients, but not in those with acute pain, those anticipating pain, or healthy people. Follow-up analyses revealed an attentional bias towards sensory pain words in the chronic pain group (d = 0.198), and the acute pain group (d = 0.303), but not other groups. In contrast, attentional biases towards affective pain stimuli were not significant for any pain groups. This meta-analysis found support for attentional biases towards sensory pain stimuli in patients with chronic pain in comparison to healthy individuals across a range of common parameters. Future researchers need to consider task design when seeking to optimally measure pain-relevant attentional biases.

  • Automatic processes and self-regulation of illness
    Health Psychol. Rev. (IF 8.597) Pub Date : 2018-07-31
    Sheina Orbell, L. Alison Phillips

    Research on the Commonsense Self-Regulation Model has emphasised reflective/conscious perceptual processes regarding illness threat (beliefs about symptoms, consequences, timeline, and curability) in predicting and changing coping behaviours. Understanding of illness self-regulation and avenues for intervention might be enriched by consideration of automatic processes that influence the recognition and identification of illness, response to illness, and ongoing management. This article adopts an integrative approach to (1) outline the theoretical importance of implicit processes in patients’ self-regulation of illness and methods to study them; (2) review research evidence for these processes, including interventions tested to modify them; and (3) outline avenues for future research. A substantial body of research on implicit processes (cognitive bias and interpretational bias) in illness maintenance in chronic illness has recently been extended to detection and interpretation of acute illness and new perspectives relating to the self-system. There is encouraging evidence that cognitive accessibility of coping and implicit attitudes may impact upon coping behaviours. Procedures that strategically automatise coping responses and create habits have considerable promise. We outline an agenda for future research in which health psychology accepts the challenge posed by the interplay of the reflective and associative systems in promoting effective self-regulation of illness.

  • The consideration of future consequences and health behaviour: a meta-analysis
    Health Psychol. Rev. (IF 8.597) Pub Date : 2018-06-28
    Lisa Murphy, Samantha Dockray

    The aim of this meta-analysis was to quantify the direction and strength of associations between the Consideration of Future Consequences (CFC) scale and intended and actual engagement in three categories of health-related behaviour: health risk, health promotive, and illness preventative/detective behaviour. A systematic literature search was conducted to identify studies that measured CFC and health behaviour. In total, 64 effect sizes were extracted from 53 independent samples. Effect sizes were synthesised using a random-effects model. Aggregate effect sizes for all behaviour categories were significant, albeit small in magnitude. There were no significant moderating effects of the length of CFC scale (long vs. short), population type (college students vs. non-college students), mean age, or sex proportion of study samples. CFC reliability and study quality score significantly moderated the overall association between CFC and health risk behaviour only. The magnitude of effect sizes is comparable to associations between health behaviour and other individual difference variables, such as the Big Five personality traits. The findings indicate that CFC is an important construct to consider in research on engagement in health risk behaviour in particular. Future research is needed to examine the optimal approach by which to apply the findings to behavioural interventions.

    Smoking in pregnancy remains a global public health issue due to foetal health risks and potential maternal complications. The aims of this systematic review and meta-analysis were to explore: (1) whether digital interventions for pregnancy smoking cessation are effective, (2) the impact of intervention platform on smoking cessation, (3) the associations between specific Behaviour Change Techniques (BCTs) delivered within interventions and smoking cessation and (4) the association between the total number of BCTs delivered and smoking cessation. Systematic searches of 9 databases resulted in the inclusion of 12 published articles (n = 2970). The primary meta-analysis produced a sample-weighted odds ratio (OR) of 1.44 (95% CI 1.04–2.00, p = .03) in favour of digital interventions compared with comparison groups. Computer-based (OR = 3.06, 95% CI 1.28–7.33) and text-message interventions (OR = 1.59, 95% CI 1.07–2.38) were the most effective digital platform. Moderator analyses revealed seven BCTs associated with smoking cessation: information about antecedents; action planning; problem solving; goal setting (behaviour); review behaviour goals; social support (unspecified); and pros and cons. A meta-regression suggested that interventions using larger numbers of BCTs produced the greatest effects. This paper highlights the potential for digital interventions to improve rates of smoking cessation in pregnancy.

    Interventions to minimise, reverse or prevent the progression of frailty in older adults represent a potentially viable route to improving quality of life and care needs in older adults. Intervention methods used across European Innovation Partnership on Active and Healthy Ageing collaborators were analysed, along with findings from literature reviews to determine ‘what works for whom in what circumstances’. A realist review of FOCUS study literature reviews, ‘real-world’ studies and grey literature was conducted according to RAMESES (Realist and Meta-narrative Evidence Synthesis: Evolving Standards), and used to populate a framework analysis of theories of why frailty interventions worked, and theories of why frailty interventions did not work. Factors were distilled into mechanisms deriving from theories of causes of frailty, management of frailty and those based on the intervention process. We found that studies based on resolution of a deficiency in an older adult were only successful when there was indeed a deficiency. Client-centred interventions worked well when they had a theoretical grounding in health psychology and offered choice over intervention elements. Healthcare organisational interventions were found to have an impact on success when they were sufficiently different from usual care. Compelling evidence for the reduction of frailty came from physical exercise, or multicomponent (exercise, cognitive, nutrition, social) interventions in group settings. The group context appears to improve participants’ commitment and adherence to the programme. Suggested mechanisms included commitment to co-participants, enjoyment and social interaction. In conclusion, initial frailty levels, presence or absence of specific deficits, and full person and organisational contexts should be included as components of intervention design. Strategies to enhance social and psychological aspects should be included even in physically focused interventions.

  • The Common Sense Model of Self-Regulation and Acceptance and Commitment Therapy: integrating strategies to guide interventions for chronic illness
    Health Psychol. Rev. (IF 8.597) Pub Date : 2018-02-15
    Maria Karekla, Evangelos C. Karademas, Andrew T. Gloster

    Most health behaviour intervention efforts are adapted from the typical psychological treatment experience and may not take into serious consideration theories specifically developed to describe the process of adaptation to illness. This paper presents a proposal for the combination of a theory about the experience of and adaptation to illness, that is, the Common Sense Model of Self-Regulation (CSM), and an efficient psychological theory and therapy, Acceptance and Commitment Therapy (ACT). Past combinations of CSM with cognitive or cognitive-behavioural interventions have focussed almost only on specific aspects of this model (mostly, illness representations and action plans) and left out other, equally important for a fruitful adaptation to illness, recommendations of the model (e.g., regarding the system coherence). Therefore, the development of the proposed combination is to try to match a broad array of the CSM aspects with the principles, intervention techniques and methods employed by ACT, in order to produce a ‘double-pillared’ intervention strategy that may prove especially effective for promoting patients’ adaptation to a chronic condition and enhancing their well-being and health.

  • How can interventions increase motivation for physical activity? A systematic review and meta-analysis

    Motivation is a proximal determinant of behaviour, and increasing motivation is central to most health behaviour change interventions. This systematic review and meta-analysis sought to identify features of physical activity interventions associated with favourable changes in three prominent motivational constructs: intention, stage of change and autonomous motivation. A systematic literature search identified 89 intervention studies (k = 200; N = 19,212) which assessed changes in these motivational constructs for physical activity. Intervention descriptions were coded for potential moderators, including behaviour change techniques (BCTs), modes of delivery and theory use. Random effects comparative subgroup analyses identified 18 BCTs and 10 modes of delivery independently associated with changes in at least one motivational outcome (effect sizes ranged from d = 0.12 to d = 0.74). Interventions delivered face-to-face or in gym settings, or which included the BCTs ‘behavioural goal setting’, ‘self-monitoring (behaviour)’ or ‘behavioural practice/rehearsal’, or which combined self-monitoring (behaviour) with any other BCT derived from control theory, were all associated with beneficial changes in multiple motivational constructs (effect sizes ranged from d = 0.12 to d = 0.46). Meta-regression analyses indicated that increases in intention and stage of change, but not autonomous motivation, were significantly related to increases in physical activity. The intervention characteristics associated with changes in motivation seemed to form clusters related to behavioural experience and self-regulation, which have previously been linked to changes in physical activity behaviour. These BCTs and modes of delivery merit further systematic study, and can be used as a foundation for improving interventions targeting increases in motivation for physical activity.

  • Harnessing centred identity transformation to reduce executive function burden for maintenance of health behaviour change: the Maintain IT model

    The inability to produce sustainable lifestyle modifications (e.g., physical activity, healthy diet) remains a major barrier to reducing morbidity and mortality from prevalent, preventable conditions. The objective of this paper is to present a model that builds on and extends foundational theory and research to suggest novel approaches that may help to produce lasting behaviour change. The model aims to integrate factors not typically examined together in order to elucidate potential processes underlying a shift from behaviour initiation to long-term maintenance. The central premise of the Maintain IT model builds on approaches demonstrating that in-tact executive function (EF) is critical for health behaviour initiation, for more complex behaviours beyond initiation, and in unsupportive environments and circumstances, but successful recruitment of EF is effortful and prone to error. Enduring changes are more likely if the underlying cognitive processes can become less effortful (non-conscious, automatic). The Maintain IT model posits that a centred identity transformation is one path leading to less effortful processing and facilitating successful recruitment of EF when necessary over the long term, increasing the sustainability of health behaviour change. A conceptual overview of the literature supporting the utility of this integrative model, future directions, and anticipated challenges are presented.

    Progress in the science and practice of health psychology depends on the systematic synthesis of quantitative psychological evidence. Meta-analyses of experimental studies have led to important advances in understanding health-related behaviour change interventions. Fundamental questions regarding such interventions have been systematically investigated through synthesising relevant experimental evidence using standard pairwise meta-analytic procedures that provide reliable estimates of the magnitude, homogeneity and potential biases in effects observed. However, these syntheses only provide information about whether particular types of interventions work better than a control condition or specific alternative approaches. To increase the impact of health psychology on health-related policy-making, evidence regarding the comparative efficacy of all relevant intervention approaches – which may include biomedical approaches – is necessary. With the development of network meta-analysis (NMA), such evidence can be synthesised, even when direct head-to-head trials do not exist. However, care must be taken in its application to ensure reliable estimates of the effect sizes between interventions are revealed. This review paper describes the potential importance of NMA to health psychology, how the technique works and important considerations for its appropriate application within health psychology.

  • A developmental cascade perspective of paediatric obesity: a conceptual model and scoping review

    Considering the immense challenge of preventing obesity, the time has come to reconceptualise the way we study the obesity development in childhood. The developmental cascade model offers a longitudinal framework to elucidate the way cumulative consequences and spreading effects of risk and protective factors, across and within biopsychosocial spheres and phases of development, can propel individuals towards obesity. In this article, we use a theory-driven model-building approach and a scoping review that included 310 published studies to propose a developmental cascade model of paediatric obesity. The proposed model provides a basis for testing hypothesised cascades with multiple intervening variables and complex longitudinal processes. Moreover, the model informs future research by resolving seemingly contradictory findings on pathways to obesity previously thought to be distinct (low self-esteem, consuming sugary foods, and poor sleep cause obesity) that are actually processes working together over time (low self-esteem causes consumption of sugary foods which disrupts sleep quality and contributes to obesity). The findings of such inquiries can aid in identifying the timing and specific targets of preventive interventions across and within developmental phases. The implications of such a cascade model of paediatric obesity for health psychology and developmental and prevention sciences are discussed.

  • The weight of fatherhood: identifying mechanisms to explain paternal perinatal weight gain

    Men appear to gain weight during the transition to parenthood, and fathers are heavier than non-fathers. Paternal perinatal weight gain may set weight trajectories in midlife and have long-term health implications. Since men do not undergo the physical demands of pregnancy and breastfeeding, the specific mechanisms underlying weight gain in new fathers warrant investigation. This review aims to stimulate research on paternal perinatal weight gain by suggesting testable potential mechanisms that (1) show change across the transition to parenthood and (2) play a role in weight and body composition. We identify seven mechanisms, within three categories: behavioural mechanisms (sleep, physical activity, and diet), hormonal mechanisms (testosterone and cortisol), and psychological mechanisms (depression and stress). We also discuss direct effects of partner pregnancy influences (e.g., ‘couvade syndrome’) on men’s body weight. In presenting each mechanism, we discuss how it may be affected by the transition to parenthood, and then review its role in body composition and weight. Next, we describe bidirectional and interactive effects, discuss timing, and present three broad research questions to propel theoretical development.

  • How effective are interventions in improving dietary behaviour in low- and middle-income countries? A systematic review and meta-analysis
    Health Psychol. Rev. (IF 8.597) Pub Date : 2018-06-07

    Several interventions encouraging people to change their diet have been tested in low- and middle-income countries (LMICs) but these have not been meta-synthesised and it is not known which elements of these interventions contribute to their effectiveness. The current review addressed these issues. Randomised controlled trials of dietary interventions in LMICs were eligible and identified via eight publication databases. Elements of both the intervention and comparison groups (e.g., behaviour change techniques (BCTs), delivery mode), participant characteristics and risk of bias were coded. Random effects meta-analysis of 76 randomised controlled trials found, on average, small- to medium-sized but highly heterogeneous improvement in dietary behaviour following an intervention. Small and homogeneous improvements were found for BMI/weight, waist- and hip-circumference, with medium-sized, but heterogeneous, improvements in blood pressure and cholesterol. Although many BCTs have yet to be tested in this context, meta-regressions suggested some BCTs (action planning, self-monitoring of outcome(s) of behaviour; demonstration of behaviour) as well as individually randomised trials, adult- or hypertensive-samples and lack of blinding were associated with larger dietary behaviour effect sizes. Interventions to encourage people from LMICs to change their diet produce, on average, small-to-medium-sized effects. These effects may possibly be increased through the inclusion of specific BCTs and other study elements.

  • Ignoring theory and misinterpreting evidence: the false belief in fear appeals
    Health Psychol. Rev. (IF 8.597) Pub Date : 2017-12-28

    Use of fear appeals assumes that when people are emotionally confronted with the negative effects of their behaviour they will change that behaviour. That reasoning is simple and intuitive, but only true under specific, rare circumstances. Risk perception theories predict that if people will experience a threat, they want to counter that threat. However, how they do so is determined by their coping efficacy level: if efficacy is high, they may change their behaviour in the suggested direction; if efficacy is low, they react defensively. Research on fear appeals should be methodologically sound, comparing a threatening to a non-threatening intervention under high and low efficacy levels, random assignment and measuring behaviour as outcome. We critically review extant empirical evidence and conclude that it does not support positive effects of fear appeals. Nonetheless, their use persists and is even promoted by health psychology researchers, causing scientific insights to be ignored or misinterpreted.

  • Does self-control modify the impact of interventions to change alcohol, tobacco, and food consumption? A systematic review

    Low self-control is associated with increased consumption of alcohol, tobacco, and unhealthy food. This systematic review aimed to assess whether individual differences in self-control modify the effectiveness of interventions to reduce consumption of these products, and hence their potential to reduce consumption amongst those whose consumption is generally greater. Searches of six databases were supplemented with snowball searches and forward citation tracking. Narrative synthesis summarised findings by: consumption behaviour (alcohol, tobacco, food); psychological processes targeted by the intervention (reflective, non-reflective, or both); and study design (experiment, cohort, or cross-sectional). Of 54 eligible studies, 22 reported no evidence of modification, 18 reported interventions to be less effective in those with low self-control, and 14 reported interventions to be more effective in those with low self-control. This pattern did not differ from chance. Whilst self-control often influenced intervention outcomes, there was no consistent pattern of effects, even when stratifying studies by consumption behaviour, intervention type, or study design. There was a notable absence of evidence regarding interventions that restructure physical or economic environments. In summary, a heterogeneous, low-quality evidence base suggests an inconsistent moderating effect of low self-control on the effectiveness of interventions to change consumption behaviours.

  • The structure of the General Health Questionnaire (GHQ-12): two meta-analytic factor analyses

    Timo Gnambs, Thomas Staufenbiel

    The General Health Questionnaire (GHQ-12) is a popular measure of psychological distress. Despite its widespread use, an ongoing controversy pertains to its internal structure. Although the GHQ-12 was originally constructed to capture a unitary construct, empirical studies identified different factor structures. Therefore, this study examined the dimensionality of the GHQ-12 in two independent meta-analyses. The first meta-analysis used summary data published in 38 primary studies (total N = 76,473). Meta-analytic exploratory factor analyses identified two factors formed by negatively and positively worded items. The second meta-analysis included individual responses of 410,640 participants from 84 independent samples. Meta-analytic confirmatory factor analyses corroborated the two-dimensional structure of the GHQ-12. However, bifactor modelling showed that most of the variance was explained by a general factor. Therefore, subscale scores reflected rather limited unique variance. Overall, the two meta-analyses demonstrated that the GHQ-12 is essentially unidimensional. It is not recommended to use and interpret subscale scores because they primarily reflect general mental health rather than distinct constructs.

    Researchers have speculated that sedentary behaviour may reduce health-related quality of life (HRQOL), but the extent to which this is true remains unknown. Our study sought to systematically review and synthesise research on the relationship between sedentary behaviours and HRQOL and to investigate if these relationships are moderated by age, health status, and HRQOL domain. The review was registered with PROSPERO (no. CRD42016036342). We searched six electronic databases. The selection process resulted in including k = 27 original studies; k = 18 were included in a meta-analysis. Data were synthesised twice, using the methods of systematic review and meta-analysis, in order to reduce biases related to a small number of included studies. Both the systematic review and meta-analytical methods indicated that lower levels of sedentary behaviours were associated with higher physical HRQOL (estimate of average effect: r = −.140; 95% CI −.191, −.088). Moderator analyses indicated that associations between the physical HRQOL domain and sedentary behaviours may be similar in strength across age- and health status groups. Causal inferences could not be drawn as most studies were cross-sectional. Concluding, sedentary behaviours were related to better physical HRQOL but not reliably to mental and social HRQOL.

  • Action and inaction in multi-behaviour recommendations: a meta-analysis of lifestyle interventions

    Dolores Albarracín, Kristina Wilson, Man-pui Sally Chan, Marta Durantini, Flor Sanchez

    This meta-analysis examined theoretical predictions about the effects of different combinations of action (e.g., start an exercise regime) and of inaction (e.g., reduce screen time, rest in between weight lifting series) recommendations in smoking, diet, and physical activity multiple-domain interventions. The synthesis included 150 research reports of interventions promoting multiple behaviour domain change and measuring change at the most immediate follow-up. The main outcome measure was an indicator of overall change that combined behavioural and clinical effects. There were two main findings. First, as predicted, interventions produced the highest level of change when they included a predominance of recommendations along one behavioural dimension (i.e., predominantly inaction or predominantly action). Unexpectedly, within interventions with predominant action or inaction recommendations, those including predominantly inaction recommendations had greater efficacy than those including predominantly action recommendations. This effect, however, was limited to interventions in the diet and exercise domains, but reversed (greater efficacy for interventions with predominant action vs. inaction recommendations) in the smoking domain. These findings provide important insights on how to best combine recommendations when interventions target clusters of health behaviours.

  • Automated telecommunication interventions to promote adherence to cardio-metabolic medications: meta-analysis of effectiveness and meta-regression of behaviour change techniques

    Aikaterini Kassavou, Stephen Sutton

    Automated telecommunication interventions, including short message service and interactive voice response, are increasingly being used to promote adherence to medications prescribed for cardio-metabolic conditions. This systematic review aimed to comprehensively assess the effectiveness of such interventions to support medication adherence, and to identify the behaviour change techniques (BCTs) and other intervention characteristics that are positively associated with greater intervention effectiveness. Meta-analysis of 17 randomised controlled trials showed a small but statistically significant effect on medication adherence, OR = 1.89, 95% CI [1.51, 2.36], I2 = 89%, N = 25,101. Multivariable meta-regression analysis including eight BCTs explained 88% of the observed variance in effect size (ES). The BCTs ‘tailored’ and ‘information about health consequences’ were positively and significantly associated with ES. Future studies could explore whether the inclusion of these and/or additional techniques (e.g., ‘implementation intentions’) would increase the effect of automated telecommunication interventions, using rigorous designs and objective outcome measures.

  • Evolutionary learning processes as the foundation for behaviour change
    Health Psychol. Rev. (IF 8.597) Pub Date : 2017-08-18
    Rik Crutzen, Gjalt-Jorn Ygram Peters

    We argue that the active ingredients of behaviour change interventions, often called behaviour change methods (BCMs) or techniques (BCTs), can usefully be placed on a dimension of psychological aggregation. We introduce evolutionary learning processes (ELPs) as fundamental building blocks that are on a lower level of psychological aggregation than BCMs/BCTs. A better understanding of ELPs is useful to select the appropriate BCMs/BCTs to target determinants of behaviour, or vice versa, to identify potential determinants targeted by a given BCM/BCT, and to optimally translate them into practical applications. Using these insights during intervention development may increase the likelihood of developing effective interventions – both in terms of behaviour change as well as maintenance of behaviour change.

  • Understanding active school travel through the Behavioural Ecological Model
    Health Psychol. Rev. (IF 8.597) Pub Date : 2017-11-23
    Samuel Ginja, Bronia Arnott, Anil Namdeo, Elaine McColl

    Active school travel (AST) is an important source of physical activity for children and a conceptual understanding of AST is necessary to inform promotion efforts. The aim of this article is to provide a conceptual analysis of AST. All currently identified AST formulations include intra-individual variables which are often recommended as intervention targets. However, existing literature lacks clarity on precisely how these intra-individual variables might shape specific AST interventions. Moreover, evaluative studies of AST interventions typically fail to specify an underpinning theory or model. To address this limitation, the Behavioural Ecological Model (BEM), not previously addressed in AST, is presented to guide this area of research. Based on specific examples, we draw attention to the role of potential antecedents and potential reinforcers of AST, as well as potential reinforcers of motorised travel. Antecedents and reinforcers may help to explain choices of school travel mode, and to inform and increase intervention options to promote AST. Consistent with the BEM, the provision of more immediate consequences, such as fun and material prizes, is an evidence-based strategy for increasing AST which is likely to be low-cost and easier to deliver than alternative interventions. This approach to the study of AST is expected to contribute to similar analyses in this and other areas of behaviour change research, and to a more useful discussion and treatment of theoretical and conceptual behavioural models.

  • Trauma exposure, posttraumatic stress, and preventive health behaviours: a systematic review
    Health Psychol. Rev. (IF 8.597) Pub Date : 2017-09-19
    Sharon Y. Lee, Crystal L. Park

    Psychological trauma has implications for many aspects of physical health, including preventive health behaviours (PHBs). However, whether trauma exposure additionally contributes to PHBs above and beyond the effects of posttraumatic stress disorder (PTSD) symptoms remains unclear. In this systematic review, 32 studies were analysed to characterise: (1) the relationships between trauma exposure and PHBs, (2) the relationships between PTSD symptoms and PHBs, (3) the unique associations between trauma exposure and PHBs, independent of PTSD symptoms, and (4) the unique associations between PTSD symptoms and PHBs, independent of trauma exposure. Findings were variable across the three examined PHBs (physical activity, diet, medical screening) when only trauma exposure or PTSD symptoms were taken into account. Clearer relationships emerged between trauma exposure and PHBs when PTSD symptoms were taken into account, demonstrating that trauma exposure is related to PHB engagement above and beyond the effects of PTSD symptoms. Additionally, PTSD symptoms shared unique associations with physical activity and screening frequency, which were not explained by trauma exposure. Our review reveals that teasing apart the effects of trauma exposure and PTSD symptoms on PHBs brings greater clarity to the strength and direction of these associations.

  • The state of the art and future opportunities for using longitudinal n-of-1 methods in health behaviour research: a systematic literature overview

    n-of-1 studies test hypotheses within individuals based on repeated measurement of variables within the individual over time. Intra-individual effects may differ from those found in between-participant studies. Using examples from a systematic review of n-of-1 studies in health behaviour research, this article provides a state of the art overview of the use of n-of-1 methods, organised according to key methodological considerations related to n-of-1 design and analysis, and describes future challenges and opportunities. A comprehensive search strategy (PROSPERO:CRD42014007258) was used to identify articles published between 2000 and 2016, reporting observational or interventional n-of-1 studies with health behaviour outcomes. Thirty-nine articles were identified which reported on n-of-1 observational designs and a range of n-of-1 interventional designs, including AB, ABA, ABABA, alternating treatments, n-of-1 randomised controlled trial, multiple baseline and changing criterion designs. Behaviours measured included treatment adherence, physical activity, drug/alcohol use, sleep, smoking and eating behaviour. Descriptive, visual or statistical analyses were used. We identify scope and opportunities for using n-of-1 methods to answer key questions in health behaviour research. n-of-1 methods provide the tools needed to help advance theoretical knowledge and personalise/tailor health behaviour interventions to individuals.

  • A scoping review of the psychological responses to interval exercise: is interval exercise a viable alternative to traditional exercise?
    Health Psychol. Rev. (IF 8.597) Pub Date : 2017-06-01
    Matthew J. Stork, Laura E. Banfield, Martin J. Gibala, Kathleen A. Martin Ginis

    While considerable evidence suggests that interval exercise confers numerous physiological adaptations linked to improved health, its psychological consequences and behavioural implications are less clear and the subject of intense debate. The purpose of this scoping review was to catalogue studies investigating the psychological responses to interval exercise in order to identify what psychological outcomes have been assessed, the research methods used, and the results. A secondary objective was to identify research issues and gaps. Forty-two published articles met the review inclusion/exclusion criteria. These studies involved 1258 participants drawn from various active/inactive and healthy/unhealthy populations, and 55 interval exercise protocols (69% high-intensity interval training [HIIT], 27% sprint interval training [SIT], and 4% body-weight interval training [BWIT]). Affect and enjoyment were the most frequently studied psychological outcomes. Post-exercise assessments indicate that overall, enjoyment of, and preferences for interval exercise are equal or greater than for continuous exercise, and participants can hold relatively positive social cognitions regarding interval exercise. Although several methodological issues (e.g., inconsistent use of terminology, measures and protocols) and gaps (e.g., data on adherence and real-world protocols) require attention, from a psychological perspective, the emerging data support the viability of interval exercise as an alternative to continuous exercise.

  • Clocking self-regulation: why time of day matters for health psychology
    Health Psychol. Rev. (IF 8.597) Pub Date : 2017-04-20
    Brett M. Millar

    Various lines of research have identified a number of factors that can impair a person’s ability and motivation to exercise self-control, here self-regulation, in the face of a tempting object (e.g., food, sex, alcohol/drugs, smoking). Each of these in situ factors – the availability of the tempting object, one’s desire for it, and impaired affective and cognitive functioning (most notably from sleep-related fatigue, daily ‘wear and tear’, and intoxication) – makes self-regulation more difficult, and even more so when they co-occur. This integrative paper highlights how time of day modulates the salience of these impairing factors and argues that they are likely to be especially influential on self-regulation at night, or later in one’s waking day. As each factor is likely to vary considerably across the 24 hours of a day, so too will one’s self-regulatory ability and motivation – although person-level characteristics such as chronotype may shift these time-based considerations. The paper thus emphasises the importance of clocking self-regulation within health psychology research and intervention design. Consideration of when a self-regulation attempt is being made and of how time of day (or night) may be altering both the person and the situation towards risk, will facilitate a more temporally contextualised account of self-regulation.

  • Evaluating the impact of method bias in health behaviour research: a meta-analytic examination of studies utilising the theories of reasoned action and planned behaviour
    Health Psychol. Rev. (IF 8.597) Pub Date : 2017-06-20
    Máirtín S. McDermott, Rajeev Sharma

    The methods employed to measure behaviour in research testing the theories of reasoned action/planned behaviour (TRA/TPB) within the context of health behaviours have the potential to significantly bias findings. One bias yet to be examined in that literature is that due to common method variance (CMV). CMV introduces a variance in scores attributable to the method used to measure a construct, rather than the construct it represents. The primary aim of this study was to evaluate the impact of method bias on the associations of health behaviours with TRA/TPB variables. Data were sourced from four meta-analyses (177 studies). The method used to measure behaviour for each effect size was coded for susceptibility to bias. The moderating impact of method type was assessed using meta-regression. Method type significantly moderated the associations of intentions, attitudes and social norms with behaviour, but not that between perceived behavioural control and behaviour. The magnitude of the moderating effect of method type appeared consistent between cross-sectional and prospective studies, but varied across behaviours. The current findings strongly suggest that method bias significantly inflates associations in TRA/TPB research, and poses a potentially serious validity threat to the cumulative findings reported in that field.

  • Should patients be optimistic about surgery? Resolving a conflicted literature
    Health Psychol. Rev. (IF 8.597) Pub Date : 2017-05-08
    Kate Sweeny, Sara E. Andrews

    Following surgery, some patients suffer distress, disappointment, regret, poor adjustment, and poor quality-of-life. Surgeons may define ‘success’ based on objective clinical outcomes, but patients’ perceptions of surgical success rely primarily on a comparison to their initial expectations. We review the literature on the relationship between patients’ surgical expectations and psychosocial outcomes and attempt to resolve a conflict in the literature. Specifically, we propose that conflicting conclusions regarding the merits of optimism primarily stem from differing methodological approaches by researchers in the field. Studies that examine preoperative expectations in isolation typically conclude that optimism is positively associated with beneficial psychosocial outcomes. Studies that compare preoperative expectations to objective surgical outcomes typically conclude that optimism, particularly unrealistic optimism, is associated with detrimental psychosocial outcomes. As a whole, the evidence strongly supports an association between optimistic expectations and positive psychosocial outcomes following surgery if those expectations are based in reality. If preoperative optimism ultimately turns out to be unrealistic, however, it is likely to be a postoperative liability.

  • Meaning in life and physical health: systematic review and meta-analysis

    Katarzyna Czekierda, Anna Banik, Crystal L. Park, Aleksandra Luszczynska

    This systematic review and meta-analysis aimed to clarify the associations between meaning in life and physical health using random-effects models. Conceptualisation of meaning (order in world vs. purpose in life), type of health indicators, participants’ health status, and age issues were investigated as moderators. Systematic searches of six databases resulted in inclusion of k = 66 studies (total N = 73,546). Findings indicated that meaning in life and physical health formed weak-to-moderate associations (the overall estimate of the average effect = 0.258). Conceptualisation of meaning, participants’ health status, and their age did not moderate these associations. Operationalisation of health moderated the relationship between meaning in life and health. The strongest associations were found for subjective indicators of physical health. Significant albeit weak associations between meaning in life and objective indices of health were found. Furthermore, stronger effects were observed when the measures of meaning combined items referring to meaning in life and meaning-related sense of harmony, peace, and well-being, compared to measures focusing solely on meaning in life. Overall, the results point to the potential role of meaning in life in explaining physical health.
