Contingent self-esteem, or self-worth hinged upon successfully meeting standards or attaining goals, requires continual maintenance and validation. Despite the inherent instability that accompanies contingent self-esteem, relatively little is known about how it relates to markers of mental health. A sample of 371 college students completed measures of self-esteem, contingent self-esteem, suicidal behaviors, and depression. Individuals with fragile low self-esteem, described as highly contingent, reported greater depressive symptoms and suicidal behavior. Among those with secure high self-esteem, or high yet noncontingent, depression and suicide risk were markedly lower. Therapeutically promoting positive but noncontingent self-worth may reduce poor mental health outcomes.

Background: Insomnia is a robust correlate of suicidal ideation and behavior. Preliminary research has identified thwarted belongingness (c.f. social disconnection) as an explanatory link between insomnia and suicidal ideation. Objectives: This study replicates and extends previous findings using both cross-sectional and longitudinal designs in four demographically diverse samples. Additionally, the specificity of thwarted belongingness was evaluated by testing anxiety as a rival mediator. Method: Self-report measures of insomnia symptoms, thwarted belongingness, suicidal ideation and behavior, and anxiety were administered in four adult samples: 469 undergraduate students, 352 psychiatric outpatients, 858 firefighters, and 217 primary care patients. Results: More severe insomnia was associated with more severe thwarted belongingness and suicidality. Thwarted belongingness significantly accounted for the association between insomnia and suicidality, cross-sectionally and longitudinally, beyond anxiety. Notably, findings supported the specificity of thwarted belongingness: anxiety did not significantly mediate the association between insomnia and suicidality, and insomnia did not mediate the relation between thwarted belongingness and suicidality. Limitations: This study relied solely on self-report measures. Future studies incorporating objective sleep measurements are needed. Conclusion: Findings underscore the utility of assessing and addressing sleep disturbances and social disconnection to reduce suicide risk.

Individuals with problem solving deficits, and higher levels of neuroticism and hopelessness, are at increased risk for suicide, yet little is known about the interrelationships between these vulnerability characteristics. In a sample of 223 low-income, primary care patients, we examined the potential mediating role of hopelessness on the relation between neuroticism and suicidal behavior, and the potential moderating role of social problem solving ability. Participants completed self-report questionnaires: Suicidal Behaviors Questionnaire-Revised, Social Problem Solving Inventory-Revised, Beck Hopelessness Scale, and NEO Five Factor Inventory. Models were tested using bootstrapped moderated mediation techniques. There was a significant indirect effect of neuroticism on suicidal behavior through hopelessness, and this indirect effect was moderated by social problem solving ability. Patients with greater neuroticism also manifest greater levels of hopelessness and, in turn, more suicidal behavior, and these relations are strengthened at lower levels of social problem solving. Interventions that increase social problem solving ability and reduce hopelessness may reduce suicide risk.

Associations between the satisfaction of basic psychological needs of autonomy, competence, and relatedness with current suicidal ideation and risk for suicidal behavior were examined. Two logistic regressions were conducted with a cross-sectional database of 440 university students to examine the association of need satisfaction with suicidal ideation and risk for suicidal behavior, while controlling for demographics and depressive symptoms. Suicidal ideation was reported by 15% of participants and 18% were found to be at risk for suicidal behavior. A one standard deviation increase in need satisfaction reduced the odds of suicidal ideation by 53%, OR (95% CI) = 0.47 (0.33–0.67), and the odds of being at risk for suicidal behavior by 50%, OR (95% CI) = 0.50 (0.37–0.69). Young adults whose basic psychological needs are met may be less likely to consider suicide and engage in suicidal behavior. Prospective research is needed to confirm these associations.

Death by suicide, and suicidal behaviors, are a significant public mental health problem, and individuals who are lesbian, gay, bisexual, transgendered and questioning (LGBTQ), may be at increased risk. Potential underlying mechanisms of this association are unknown, but may involve the impact of LGBTQ status on future orientation and mood. Our purpose was to determine the influence of sexual identity, sequentially, on cognitive and emotional functioning, and consequent relation to suicidal behavior. In a sample of 349 college students, we used serial mediation models to investigate the relation between self-identification as LGBTQ and suicidal behavior, with hope and hopelessness as first-order mediators and depression as a second order mediator. Supporting hypotheses, we found that LGBTQ status was related to less hope and greater hopelessness and, in serial fashion, to depressive symptoms and consequent suicidal behavior. Our findings may have clinical implications. Resolution of hopelessness and depression, and promotion of hopefulness, perhaps via Motivational Interviewing and Cognitive Behavioral Therapy strategies, such as goal-setting, may reduce suicidal risk in LGBTQ young adults.
