The prevalence of suicidal ideation/behavior in 1983 or 1987 and its association with future mental health in 2001 were evaluated in a provincially representative sample of Canadian adolescents (n = 1,248) aged 12 to 16 years. Approximately 13.3% (95% CI = 11.5–15.3) of adolescents self‐reported suicidal ideation/behavior. Adolescent agreement with parent (κ = .07) and teacher (κ = .05) reports at baseline was low because adults identified so few subjects. In adulthood, the associations between adolescent self‐reports of suicidal behavior/ideation and major depression and other mental health indicators were explained by respondent sex and adolescent emotional problems reported in 1983/1987. Adolescents with suicidal behavior/ideation often are not recognized by their parents and teachers and may be at risk for persistent psychiatric problems attributable to coexisting mental health problems early‐on. 相似文献

Mindfulness‐based meditation practices have received substantial scientific attention in recent years. Mindfulness has been shown to bring many psychological benefits to the individual, but much less is known about whether these benefits extend to others. This meta‐analysis reviewed the link between mindfulness – as both a personality variable and an intervention – and prosocial behaviour. A literature search produced 31 eligible studies (N = 17,241) and 73 effect sizes. Meta‐analyses were conducted using mixed‐effects structural equation models to examine pooled effects and potential moderators of these effects. We found a positive pooled effect between mindfulness and prosocial behaviour for both correlational (d = .73 CI 95% [0.51 to 0.96]) and intervention studies (d = .51 CI 95% [0.37 to 0.66]). For the latter, medium‐sized effects were obtained across varying meditation types and intensities, and across gender and age categories. Preliminary evidence is presented regarding potential mediators of these effects. Although we found that mindfulness is positively related to prosociality, further research is needed to examine the mediators of this link and the contexts in which it is most pronounced. 相似文献

Although there is growing evidence that strong informal influence hierarchies can enhance teams' core task performance, recent theorising suggests that such informal hierarchies may, at the same time, stifle team creativity. The current study draws from the Motivated Information Processing in Groups (MIP-G) model to empirically examine this latter notion. Moreover, we build on functional leadership theories to propose that the link between informal hierarchy strength and team creativity hinges on a formal team leader's empowering leadership. Using a sample of 56 organisational work teams comprising 304 individuals from a wide range of industries, we found that stronger informal influence hierarchies related negatively with team creativity when the formal leader exhibited little empowering behaviour. When the formal leader acted in more empowering ways, by contrast, this negative relationship was dampened. These findings provide new knowledge on the role of informal influence hierarchies for team creativity and advance our understanding of how informal hierarchical relations and formal leadership processes can jointly shape important team outcomes. 相似文献

Decision making in the prisoner's dilemma game: The effect of exit on cooperation and social welfare
Tessa Haesevoets Dries H. Bostyn Chris Reinders Folmer Arne Roets Alain Van Hiel 《决策行为杂志》2019,32(1):61-78
The prisoner's dilemma game is a mixed‐motive game that offers two players the simultaneous choice between a cooperative and a defective alternative. An often neglected aspect of such a binary‐choice game, however, is that in many real‐life encounters, people can choose not only to cooperate or defect, but they also have a third option: to exit the social dilemma. Although in the literature a consensus has emerged that the addition of an exit opportunity benefits cooperation, there is only scant research into its effect on social welfare. In order to allow a direct comparison of cooperation rates and welfare levels across binary‐choice and trinary‐choice games, in this study, we used a design in which the same participants played similar games with and without an exit option (i.e., a within‐subjects design), and this in a range of structural variations. The findings of our study indicated that the aggregated outcome of both players is generally lower in games with an exit option than in games without an exit option. Moreover, our results showed that the efficiency of the exit option strongly depends on the specific outcome structure of the game (in terms of its endowment size, (a)symmetry, and level of noncorrespondence). In the discussion, it is argued that the implementation of an exit option as a strategy to increase social welfare should be critically assessed. 相似文献

This two‐wave field study draws from social cognitive theory to investigate the specific job search self‐efficacy beliefs and behaviors of unemployed ethnic minority women in the Netherlands. We go beyond prior job search research that predominantly used white samples and conceptualized job search self‐efficacy and behavior as global, unidimensional constructs. We found that networking self‐efficacy and Internet self‐efficacy were the main predictors of ethnic minority women’s job search behaviors. Moreover, the more time they spent on contacting employment agencies and looking at job ads the more job offers they received. Finally, time spent on job ads was more positively related to job offers when job ad self‐efficacy was high and time spent on networking only predicted job offers when networking self‐efficacy was high. 相似文献

Amygdala–orbitofrontal connectivity predicts alcohol use two years later: a longitudinal neuroimaging study on alcohol use in adolescence 下载免费PDF全文

This study tested the relation between cortical–subcortical functional connectivity and alcohol consumption in adolescents using an accelerated longitudinal design, as well as normative developmental patterns for these measures. Participants between ages 8 and 27 completed resting‐state neuroimaging scans at two time points separated by two years (N = 274 at T1, N = 231 at T2). In addition, participants between ages 12 and 27 reported on recent and lifetime alcohol use (N = 193 at T1, N = 244 at T2). Resting‐state connectivity analyses focused on amygdala–orbitofrontal connectivity given prior research linking reduced coupling between these regions to alcohol use. Mixed model analyses revealed that age had a cubic relationship with alcohol use, with little to no use in childhood, steep increases in adolescence and leveling off in adulthood. No age effects were found for amygdala–OFC connectivity. Prediction analyses showed that left amygdala–orbitofrontal connectivity at the first time point predicted recent and lifetime alcohol use two years later. There was no evidence for the reversed relation, suggesting that brain connectivity measures precede explorative risk‐taking behavior in adolescence, possibly because decreased subcortical–frontal connectivity biases towards more explorative or risky behavior. 相似文献

Background and Objectives: Involvement in wartime combat often conveys a number of deleterious outcomes, including posttraumatic stress disorder (PTSD), depression, hostility, aggression, and suicidal ideation. Less studied is the effect of engagement in wartime atrocities, including witnessing and perpetrating abusive violence.Design and Methods: This study employed path analysis to examine the direct effects of involvement in wartime atrocities on hostility, aggression, depression, and suicidal ideation independent of combat exposure, as well as the indirect effects via guilt and PTSD symptom severity among 603 help-seeking male Vietnam War veterans.Results: Involvement in wartime atrocities was predictive of increased guilt, PTSD severity, hostility, aggression, depressive symptoms, and suicidal ideation after controlling for overall combat exposure. Combat-related guilt played a minor role in mediating the effect of atrocity involvement on depression and suicidal ideation. PTSD severity had a larger mediational effect. However, it still accounted for less than half of the total effect of involvement in wartime atrocities on hostility, aggression, and suicidal ideation.Conclusions: These findings highlight the heightened risk conveyed by involvement in wartime atrocities and suggest that the psychological sequelae experienced following atrocity involvement may extend well beyond guilt and PTSD. 相似文献
