Chronic loneliness is associated with a range of mental health difficulties. Previous theory and research indicate that psychological interventions show promise for reducing loneliness, however, there have been no systematic reviews or meta-analyses to ascertain the efficacy of these interventions across the lifespan. The aim of this study was to synthesise, meta-analyse and explore the heterogeneity

Cognitive flexibility can be thought of as the ability to effectively adapt one's cognitive and behavioural strategies in response to changing task or environmental demands. To substantiate the common inference that self-report and neuropsychological tests of cognitive flexibility provide ‘different windows into the same room’, we undertook a systematic review and meta-analysis to determine whether

People differ in their self-reported propensities to experience positive affect (PA). Even those prone to internalizing symptoms show varied proclivities to PA; social anxiety (SA), for instance, unlike other types of anxiety, shows a strong negative association with PA that cannot be explained by diminished reward sensitivity. Heightened reliance on suppression of emotional displays (expressive suppression;

Psychological interventions have been proven to be effective to prevent depression, however, little is known on the cost-effectiveness of psychological interventions for the prevention of depression in various populations. A systematic review was conducted using PubMed, PsycINFO, Web of Science, Embase, Cochrane Central Register of Controlled Trials, Econlit, NHS Economic Evaluations Database, NHS

Individuals with schizophrenia-spectrum disorders face profound challenges as they attempt to maintain identity through the course of illness. Narrative identity—the study of internalized, evolving life stories—provides a rich theoretical and empirical perspective on these challenges. Based on evidence from a systematic review of narrative identity in the psychosis spectrum (30 studies, combined N = 3859)

Depression is associated with reduced motivation to engage in previously enjoyed activities. In particular, anhedonia has been linked to reduced motivation, though other depressive symptoms may also play a role. The purposes of this systematic review were to 1) examine the relationship between depression and motivation, as operationalized by a willingness to expend effort for rewards, 2) examine the

This review assessed the efficacy of adapted psychological interventions for Black and minority ethnic (BME) groups. A conceptual typology was developed based on adaptations reported in the literature, drawing on the common factors model, competence frameworks and distinctions between types of cultural adaptations. These distinctions were used to explore the efficacy of different adaptations in improving

Some individuals with posttraumatic stress disorder (PTSD) are at elevated risk of reexposure to trauma during treatment. Trauma-focused cognitive-behavioral therapies (CBT) are recommended as first-line PTSD treatments but have generally been tested with exclusion criteria related to risk for trauma exposure. Therefore, there is limited knowledge on how to best treat individuals with PTSD under ongoing

Repetitive negative thinking (RNT) and executive functioning (EF) deficits are each characteristic of many forms of youth psychopathology. Extensive work has examined the relationship between rumination, a form of RNT, and EF in adults. However, less is known about the relationship between RNT more broadly and EF in youth, for whom these constructs are developing and emerging. Here, we systematically

Despite years of research demonstrating a relation between personality pathology and intimate partner violence (IPV), no meta-analysis has been published examining how well, or poorly, all ten personality disorders (PDs) predict IPV perpetration or victimization, nor has any meta-analysis examined these relations across types of IPV. Therefore, the present study was undertaken to synthesize existing

Self-harm behavior can begin in early adolescence, with the highest rates of self-harm, between 1990 and 2000 in England, being among adolescents aged 16 to 24 years and there being considerable risk of fatal and non-fatal repetition. Previous systematic reviews have identified risk factors for self-harm in adolescents, but not for the repetition of this behavior. The aim of this review was to synthesise

This meta-analytic study synthesized findings from 108 independent data sets across 22 cultures to investigate whether the stigma internalization model (the internalization of experienced stigma and perceived stigma to self-stigma) is associated with well-being and recovery of people with mental illness. We also examined the moderating role of collectivism in the internalization process. Results of

This report provides a review of randomized controlled trials that tested whether an eating disorder prevention program significantly reduced future onset of eating disorders, which is important because eating disorders are common and result in marked functional impairment. We identified 15 trials involving 5080 participants (mean ages ranging from 14.5 to 22.3) that reported 19 tests of whether selective

Despite considerable public and scholarly debate about the role of social media in self-injurious thoughts and behaviors (SITBs), no comprehensive, quantitative synthesis of this literature has previously been undertaken. The current systematic review and meta-analysis examines associations between social media use and SITBs, including suicidal ideation, suicide plans, suicide attempts, and nonsuicidal

Bipolar spectrum disorders (BSDs) and substance use disorders (SUDs) are associated with neural reward dysfunction. However, it is unclear what pattern of neural reward function underlies pre-existing vulnerability to BSDs and SUDs, or whether neural reward function explains their high co-occurrence. The current paper provides an overview of the separate literatures on neural reward sensitivity in

The aim of this systematic review and meta-analysis was to provide a comprehensive evaluation of the role of emotion (dys)regulation in gambling disorder (GD). PsycINFO, PsycARTICLES, MEDLINE, Scopus, Web of Science, and PubMed were systematically searched for articles published until November 3, 2020. Forty-nine studies were considered for the systematic review; of these, 38 comprising 5242 participants

Meta-analytic methods were used to examine ADHD-related risk-taking in children and adults, and to compare the magnitude of risk taking across behavioral, self-report, and virtual reality metrics. Potential moderators of effect size heterogeneity were also examined via a three-level multi-level approach and a hybrid meta-analytic/systematic review approach. Aggregated effect sizes obtained from 56

A large body of research has emerged over the last decade examining empirical models of general and specific psychopathology, which take into account comorbidity among psychiatric disorders and enable investigation of risk and protective factors that are common across disorders. This systematic review presents findings from studies of empirical models of psychopathology and transdiagnostic risk and

Heterogeneity within autism spectrum disorder (ASD) is recognized as a challenge to both biological and psychological research, as well as clinical practice. To reduce unexplained heterogeneity, subtyping techniques are often used to establish more homogeneous subtypes based on metrics of similarity and dissimilarity between people. We review the ASD literature to create a systematic overview of the

Respiratory sinus arrhythmia (RSA) reactivity is thought to indicate how adaptively one responds to stress. RSA reactivity has been examined across anxiety disorders and posttraumatic stress disorder (PTSD), to better understand the psychophysiological stress response of these disorders. The current state of the literature is mixed, and the association between RSA reactivity and PTSD/anxiety is unclear

A substantial proportion of adults with eating disorders are parents. Studies suggest these parents may experience a range of parenting challenges, and their children may be at an increased risk for the development of eating disorders themselves. With parenting practices being one potential environmental mechanism for the intergenerational transmission of eating disorders, we systematically searched

Comorbid borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD) is a severe and complicated clinical presentation characterized by especially high rates of suicide, healthcare utilization, and psychosocial impairment. Although guidelines exist for treating each of these disorders alone, there remains limited guidance on the optimal treatment in cases where BPD and PTSD co-occur

Early response is a well-established predictor of positive outcomes at the end of psychological treatments for common mental disorders. There is some prior evidence that this conclusion also applies to eating disorders, including three meta-analyses, but no moderators of that relationship have been identified. However, a number of further papers have been published since, which might influence the

Research into cognitive functions across psychological disorders suggests that cognitive deficiencies may be present across multiple disorders, potentially pointing to a transdiagnostic phenomenon. More recently, a single dimension model of psychopathology, the p factor, has been proposed, in which cognitive deficits are thought to be an intrinsic construct, assumed to be transdiagnostic. However,

Post-traumatic stress disorder (PTSD) is a common mental health condition that requires exposure to a traumatic event. This provides unique opportunities for prevention that are not available for other disorders. The aim of this review was to undertake a systematic review and evaluation of randomized controlled trials (RCTs) of interventions designed to prevent PTSD in adults. Searches involving Cochrane

Purpose Whilst it is generally accepted that supportive relationships facilitate recovery from psychosis, much less is known about the role of romantic relationships in people with psychosis. This review aimed to synthesise quantitative literature regarding the impact of romantic relationships on the mental health and general wellbeing of people who experience psychosis. Method A systematic review

How fathers cope with stress may be critical to their mental health during the perinatal period. Using a sequential explanatory design for systematic review and meta-analysis, we aimed to identify associations and causal relations between higher- and lower-order avoidant and approach coping strategies and paternal psychopathology. We searched five electronic databases and grey literature, and used

Over the last few decades, clinical psychologists have played a key role in the development of empirically-validated psychosocial interventions for those with serious mental illness (SMI). However, in contrast to these substantial contributions, clinical psychologists in the United States are grossly underrepresented in treatment provision with this population (Roe, Yanos, & Lysaker, 2006; Rollins

An increase in time spent on screen-based technologies has been suggested to underlie recent increases in mental health problems among young people. However, this hypothesis has primarily been based on the findings of cross-sectional studies. The aim of the current review was to provide a comprehensive overview of longitudinal studies examining the relationship between screen time and internalising

The Research Domain Criteria (RDoC) and the Hierarchical Taxonomy of Psychopathology (HiTOP) represent major dimensional frameworks proposing two alternative approaches to accelerate progress in the way psychopathology is studied, classified, and treated. RDoC is a research framework rooted in neuroscience aiming to further the understanding of transdiagnostic biobehavioral systems underlying psychopathology

Intervention at the earliest illness stage, in ultra or clinical high-risk individuals, or indicated prevention, currently represents the most promising strategy to ameliorate, delay or prevent psychosis. We review the current state of evidence and conduct a broad-spectrum meta-analysis of various outcomes: transition to psychosis, attenuated positive and negative psychotic symptoms, mania, depression

Despite evidence supporting a role for oxytocin (OT) in regulating social behavior, surprisingly little is known about how this neuropeptide is calibrated during development. We systematically reviewed empirical studies in humans (k = 86 publications reporting on 66 independent samples; N = 7319) that examined associations between early-life stress and three OT system components: endogenous OT, methylation

In this meta-analysis we updated a review from 2013 investigating the evidence on the efficacy of hypnosis in adults undergoing surgical procedures compared to standard care alone or an attention control. A comprehensive literature search using Medline, CENTRAL, Web of Science, PsycINFO, ProQuest Dissertations and Theses database, and manual searches were conducted to identify randomized controlled

Progress feedback is an intervention aimed at enhancing patient outcomes in routine clinical practice. This study reports a comprehensive multilevel meta-analysis on the effectiveness of progress feedback in psychological treatments in curative care. The short- and long-term effects of feedback on symptom reduction were investigated using 58 (randomized and non-randomized) studies, analyzing 110 effect

The intellectual tradition of individualism treats the individual person as the fundamental unit of analysis and reduces all things social to the motives and actions of individuals. Most methods in clinical psychology are influenced by individualism and therefore treat the individual as the primary object of therapy/training, even when recognizing the importance of nurturing social relationships for

People with psychosis are reported to be one of the most stigmatised minority groups in society. Mental health stigma can have a detrimental impact on quality of life (QoL), which is a meaningful outcome for service users experiencing psychosis and using mental health services. This paper provides the first systematic literature review, meta-analysis and quality appraisal of studies examining the association

There has been a marked increase of network studies of Major Depressive Disorder (MDD). Despite rapidly growing contributions, their findings have yet to be systematically aggregated and examined. We therefore conducted a systematic review of depression network studies using PRISMA guidelines. A total of 254 clinical and population studies were collected from ISI's Web of Science and PsycINFO, between

The COVID-19 pandemic has and will continue to result in negative mental health outcomes such as depression, anxiety and traumatic stress in people and populations throughout the world. A population mental health perspective informed by clinical psychology, psychiatry and dissemination and implementation science is ideally suited to address the broad, multi-faceted and long-lasting mental health impact

Social support has long been associated with posttraumatic stress disorder (PTSD), but there is no consistent evidence on the strength and direction of this relationship. Whereas the social causation model claims that social support buffers against PTSD, the social selection model states that PTSD reduces social support resources. As the first meta-analysis of the prospective relationships between

In recent years a large array of treatment protocols conceptualized as transdiagnostic have been developed with clinical and practical advantages compared to traditional single-disorder protocols. Within this panorama, the Transdiagnostic Unified Protocol (UP) of Emotional Disorders was developed aimed at treating the negative affective processes underlying several diagnostic categories, and accounting

In recent years, research and practice on adverse childhood experiences (ACEs) have shifted from delineating effects of ACEs on adulthood health problems to preventing ACEs in children. Nonetheless, little attention has focused on how parents' own childhood experiences, adverse or positive, may influence the transmission of ACEs across generations. Children's risk for ACEs and potential for resilience

Although self-compassion has been extensively studied in the recent decades, the representation of self-compassion as a unitary measure or the presence of self-warmth (i.e., presence of the positive components: self-kindness, common humanity, and mindfulness) and self-coldness (i.e., presence of the negative components: self-judgment, isolation, and mindfulness) remains controversial. Moreover, the

The current research examined the bidirectional effects between internalizing problems and peer victimization within a meta-analytic framework. The study also investigated several potential moderators of these effects which have not been examined previously in relation to meta-analytic studies. Only longitudinal studies examining the association between internalizing symptoms and peer victimization

The study of temperament in Autism Spectrum Disorder (ASD) has the potential to provide insight regarding variability in the onset, nature, and course of both core and co-morbid symptoms. The aim of this systematic review was to integrate existing findings concerning temperament in the context of ASD. Searches of Medline, PsychInfo and Scopus databases identified 64 relevant studies. As a group, children

Although many attempts have been made to limit development of posttraumatic stress disorder (PTSD) by early intervention after trauma exposure, these attempts have achieved only modest success. This review critiques the biological and cognitive strategies used for early intervention and outlines the extent to which they have prevented PTSD. The major predictors of PTSD are reviewed, with an emphasis

Theoretical accounts and preliminary evidence suggest that Mindfulness-Based Interventions (MBIs) improve cognitive function, but reviews of empirical studies have provided mixed results. To clarify empirical evidence, we conducted a meta-analysis of 25 studies (n = 1439) and examined the effects of MBIs on four cognitive domains: attention, working memory, long-term memory, and executive function

Decades of research implicates perfectionism in depressive symptoms. Yet, inconsistent findings, underpowered studies, and the tendency for researchers to assume one direction of influence have clouded understanding of whether perfectionism is a vulnerability factor for depressive symptoms, a complication of depressive symptoms, or both. Our primary aim was to address this by using meta-analytic structural

Psychological flexibility (PF) is a popular construct in clinical psychology. However, similar constructs have existed since the mid-20th century, resulting in different terms, definitions and measures of flexibility, hindering the advancement of the field. The main measure of PF – the Acceptance and Action Questionnaire (AAQ-II; Bond et al., 2011) – has also been heavily criticized. To move towards

Objective Respiratory abnormalities are a hallmark of anxiety symptomatology and may serve as clinically useful modifiers for alleviating anxiety symptoms. However, gold-standard anxiety treatments (e.g., cognitive-behavioral interventions) often do not directly address respiratory components despite their theoretical utility and clinical accessibility. This review examined the clinical effectiveness

Prominent explanatory models for borderline personality disorder (BPD) are intrapersonal in nature and hold that it is an emotional disorder. However, the empirical support for emotional models of BPD is mixed. Refinements to BPD explanatory models are needed to increase the precision with which BPD can be understood and treated. Drawing on existing theoretical and empirical research in BPD, this manuscript

The opioid epidemic is a public health problem associated with a host of negative outcomes. Although clinicians recognize covariation between opioid misuse with anxiety and depressive symptoms and disorders, research on this topic has only recently accumulated. Progress in this domain is impeded by the lack of systematic and integrative research to better understand and treat these co-occurring problems

Binge drinking is a widespread alcohol consumption pattern commonly engaged by youth. Here, we present the first systematic review of emotional processes in relation to binge drinking. Capitalizing on a theoretical model describing three emotional processing steps (emotional appraisal/identification, emotional response, emotional regulation) and following PRISMA guidelines, we considered all identified

Background Previous reviews of interventions to prevent recidivistic intimate partner violence (IPV) have cited minimal benefits and have been critical of interventions adopting a ‘one-size-fits-all’ approach to a heterogenous category of offenders. The present systematic review and meta-analysis assesses evidence for interventions situated in a risk-need-responsivity framework, in comparison with

Policy changes have resulted in dramatic increases in access to cannabis for medical purposes. Veterans are disproportionately affected by conditions for which medical cannabis is often pursued, making an evidence-based perspective on risks versus benefits of high priority. The current review sought to examine the state of the evidence on the correlates and consequences of cannabis use among veterans

The efficacy of Internet- and mobile-based interventions (IMIs) for depression in adults is well established. Yet, comprehensive knowledge on the mediators responsible for therapeutic change in these interventions is pending. Therefore, we conducted the first systematic review on mediators in IMIs for depression, investigating mechanisms of change in interventions with different theoretical backgrounds

Various Cognitive Behavioral Therapy (CBT) programs for externalizing disorders in children and adolescents are supported by a substantial body of empirical evidence. Most of the research evidence comes from efficacy studies conducted in university settings, but there is less knowledge about the effect of these treatments in routine clinical care. The purpose of this meta-analysis was to investigate

Beliefs about the malleability of attributes, also known as mindsets, have been studied for decades in social-personality psychology and education. Here, I review the many applications of mindset theory to clinical psychology and psychotherapy. First, I review social psychological and cognitive neuroscience evidence that mindsets and mindset-related messages are, to a large extent, focused on emotional
