Factors underlying the association between intimate relationship breakdown and men's suicidality are poorly understood. This systematic review and meta-analysis examined which men are most vulnerable and the factors underpinning men's suicidal ideation, suicide attempt, and death by suicide following relationship breakdown. We reviewed 75 studies across 30 countries (N ≥ 100 million men). Of these

Several meta-analyses on hand preference in mental and neurodevelopmental disorders have been published in the last decade. Some disorders, like schizophrenia, have been associated with increased rates of atypical hand preference (i.e., non-right-, left-, or mixed-hand preference)-but others, like depression, have not. To identify overarching patterns between hand preference and psychopathology and

Humans often face moral dilemmas posing a conflict between two motives: deontology (rule-following, e.g., "thou shalt not kill") and utilitarianism (greater-good-maximization, e.g., sacrificing one for many). A long-standing debate concerns the influence of cognitive processing on moral judgments in such dilemmas. One popular dual process account suggests that intuition favors "deontological" judgments

The upsurge in the prevalence of contested, ambiguous, and difficult-to-diagnose illnesses presents challenges for clinicians who too often respond by invalidating patients' symptoms. Although numerous qualitative studies have reported the effects of invalidation on patients' psychological and behavioral outcomes, this body of research has not been systematically reviewed. Informed by Linehan's (1993)

Reduced autobiographical memory (AM) specificity, characterized by difficulty recalling specific past events, is a feature of multiple psychiatric disorders. While meta-analyses indicate that reduced AM specificity can predict future symptom severity, its role as a premorbid risk factor for mental illness onset in young people remains unclear. Our preregistered individual participant data meta-analysis

Research on social hierarchy is flourishing. Often, researchers employ self- or peer-report measures to assess variables such as power or dominance. One drawback of studies in this line of research is that researchers use different scales to measure the same constructs and different researchers use the same scale but aim to measure different constructs. Moreover, hierarchy concepts have been used interchangeably

Two theoretical perspectives (i.e., the risk management perspective and the resource perspective) offer competing predictions that higher class individuals-relative to lower class individuals-tend to be less versus more prosocial, respectively. Different predictions can also be drawn from each perspective about how the class-prosociality association varies across sociocultural contexts. To date, each

Interoceptive exposure (IE) involves the use of exercises, activities, or tasks to intentionally induce (or exacerbate) physical symptoms in the body, to challenge misconceptions about the harmful nature of the physical symptoms that maintain fear and problematic avoidance. IE was originally developed for the cognitive behavioral treatment and prevention of panic disorder. Bodily sensations and concern

Confronting prejudice is a promising strategy for reducing intergroup bias. The current meta-analysis estimated the effects of confronting prejudice on intergroup bias in the confronted person and examined the impact of potential moderators. Eligible studies measured intergroup bias in participants confronted versus not confronted for intergroup bias. A three-level mixed-effects analysis on 91 effect

As older women drive aging population trends, it is crucial to understand how target age and gender jointly influence perceiver attitudes. Although the prevailing "double jeopardy" perspective portrays older women as the most derogated age-gender group due to facing both age and sex bias, some evidence suggests gender attitudes converge with target age (i.e., a "convergence" perspective). Investigating

Teacher-student relationships (TSRs) play a vital role in establishing a positive classroom climate and promoting positive student outcomes. Several meta-analyses have suggested significant correlations between positive TSRs and, for example, academic achievement, motivation, executive functions, and well-being, as well as between negative TSRs that result in behavior problems or bullying. These meta-analyses

Belief in conspiracy theories has been linked to harmful consequences for individuals and societies. In an effort to understand and mitigate these effects, researchers have sought to explain the psychological appeal of conspiracy theories. This article presents a wide-ranging systematic review and meta-analysis of the literature on conspiracy beliefs. We analyzed 971 effect sizes from 279 independent

Family-based treatments provided around the world for children with mental health, physical health, and developmental disorders often convey secondary mental health benefits to caregivers and siblings who participate in those treatments. Yet, there are no systematic evaluations of these secondary benefits, suggesting that current estimates of the effectiveness of family treatments do not accurately

This meta-review provides the first meta-analytic evidence from published meta-analyses examining the effectiveness of acute exercise interventions on cognitive function. A multilevel meta-analysis with a random-effects model and tests of moderators were performed in R. Thirty systematic reviews with meta-analyses (383 unique studies with 18,347 participants) were identified. Acute exercise significantly

Decades of research highlight that differential treatment can have negative developmental consequences, particularly for less favored siblings. Despite this robust body of research, less is known about which children in the family tend to be favored or less favored by parents. The present study examined favored treatment as predicted by birth order, gender, temperament, and personality. We also examined

In understanding the nature of mathematical skills, the most influential theories suggest that mathematical cognition draws on different systems: numerical, linguistic, spatial, and general cognitive skills. Studies show that skills in these areas are highly predictive of outcomes in mathematics. Nonetheless, the strength of these relations with mathematical achievement varies, and little is known

This meta-analysis studied the development of ability stereotypes that could limit girls' and women's participation in science, technology, engineering, and mathematics (STEM) fields, as well as contribute to boys' underachievement in reading and writing. We integrated findings from 98 studies measuring children's gender stereotypes about STEM and verbal abilities. The data comprised 145,204 children

This first-of-its-kind meta-analysis (N = 79 studies; 56,552 students; k = 640 effects) provides a comprehensive assessment of five cultural diversity climate approaches that capture different ways of addressing cultural diversity in K-12 schools. We examined how intergroup contact theory's optimal contact conditions, multiculturalism climate, colorblind climate, critical consciousness climate, and

Research has suggested that the endorsement of ideologies supporting the status quo leads to higher subjective psychological well-being-an idea labeled as the palliative function of ideology within system justification theory. Furthermore, this approach has suggested that this association should be moderated by social status. Specifically, the association between the endorsement of ideologies supporting

People's subjective beliefs about themselves affect what people think and, consequently, what they do. Positive self-beliefs are important for many life outcomes, from academic success to well-being, especially during K-12 education as a crucial developmental period. Many empirical studies and meta-analyses have examined correlates of self-beliefs. The present second-order meta-analytic review integrates

Evidence has ostensibly been accumulating over the past 2 decades suggesting that an external focus on the intended movement effect (e.g., on the golf club during a swing) is superior to an internal focus on body movements (e.g., on your arms during a swing) for skill acquisition. Seven previous meta-studies have all reported evidence of external focus superiority. The most comprehensive of these concluded

We conducted a multilevel meta-analysis of 390 effect sizes from 167 studies with 157,923 participants examining the relationship between connectedness with lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ+) communities and health-related outcomes, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We conducted our initial search in January 2023

Social rewards are strong drivers of behavior and fundamental to well-being, yet there is a lack of consensus regarding what actually defines a reward as "social." Because a systematic overview of existing social reward operationalizations is currently absent, a review of the literature seems necessary to advance toward a unified framework and to better guide research and theory. To bridge this gap

The core premise of cognitive appraisal theories of emotion is that emotions are produced from our interpretation of what we experience. Compared to other major theoretical frameworks in emotion, the appraisal perspective emphasizes the centrality of these cognitive interpretations in giving rise to emotions. Decades of research have yielded numerous studies that broadly agree on the centrality of

Researchers and policymakers aspire for educational interventions to change children's long-run developmental trajectories. However, intervention impacts on cognitive and achievement measures commonly fade over time. Less is known, although much is theorized, about social-emotional skill persistence. The current meta-analysis investigated whether intervention impacts on social-emotional skills demonstrated

Due to the vital role of empathy in promoting prosocial behaviors and nurturing social bonds, there is a growing interest in cultivating empathy. Yet, the effectiveness of existing training methods on empathy, especially on different dimensions of empathy (i.e., affective, cognitive, motivational, and behavioral empathy), varies tremendously, and the underlying causes for this heterogeneity remain

Self-determination theory (Ryan & Deci, 2017) has highlighted the differential roles that intrinsic life goals (for personal growth, close relationships, community connections, and physical health) and extrinsic life goals (i.e., for wealth, image, and status) play in supporting well-being. Less is known about how orientations toward these two types of aspirations develop. It is likely that early environmental

Executive function (EF), the set of mental processes and skills involved in goal-oriented planning, organizing, and controlling behavior, is believed to support child development across many domains of life. However, although ample evidence suggests a relation between childhood EF and academic skills, it is less clear what its role is in domains beyond academics. We report a meta-analysis of relations

Children's ability to accurately recognize the external emotional signals produced by those around them represents a milestone in their socioemotional development and is associated with a number of important psychosocial outcomes. A plethora of individual studies have examined when, and in which order, children acquire emotion knowledge over the course of their development. Yet, very few attempts have
