Does optimism weaken the negative effects of being lonely on suicide risk?

Association between the dispositional optimism and depression in young people: a systematic review and meta-analysis

The objective of this study was to perform a meta-analysis of publications that reported the association between dispositional optimism and depression during youth, analyzing if the strength of this relationship varied according to potential factors. Systematic searches were carried out in APA PsycNet, Virtual Health Library, Embase, Web of Science, PubMed Central, and Scopus to collect English, Portuguese, or Spanish studies from 2009 onwards. Two reviewers selected the eligible articles, assessed the quality of each study, and extracted the data. For the synthesis of the results, a meta-analytic approach was used. We identified 4077 publications in the initial searches and 22 in the supplementary searches, from which 31 studies remained for analysis once the eligibility criteria were applied. The results showed a statistically significant negative association between dispositional optimism and depression in the young population, age being a factor that modifies the effect measure between these variables. This meta-analysis provides a consistent and robust synthesis on the interaction effect between dispositional optimism and depression in the young population. Based on these findings, early clinical admissions may effectively improve optimistic tendencies in young people, which could help them prevent depressive symptoms or episodes.

Optimism and gratitude on suicide risk in Spanish adults: Evidence for doubling up or doubling down?

OBJECTIVE

The present study examines the role of optimism and gratitude as predictors of suicide risk, namely depressive symptoms and suicide ideation. Beyond their expected predictive role, optimism and gratitude were also hypothesized to interact together to predict both suicide risk outcomes.

METHODS

A sample of 1,013 Spanish adults (521 females) participated in this study. The average age was 39.63 years old (standard deviation = 16.19; range 16-82).

RESULTS

Results indicated that the optimism × gratitude interaction term significantly augmented the prediction of both depressive symptoms and suicide ideation. Specifically, pessimists presented with a higher risk of suicide, but the effect was weaker among those individuals with higher levels of gratitude. Alternatively, optimists with high gratitude showed the highest amount of protection from suicide risk.

CONCLUSIONS

Our findings are the first to show how optimism and gratitude might interact as a positive psychological variable to confer greater personal resources in protecting individuals against suicide risk.

A New Brief Scale to Measure Optimism

This research was done to find if using maximum likelihood could reduce the Interactive Optimism Scale-Garcia to a new valid and reliable shorter version. There were 502 adults: 263 women and 239 men (M_age = 34.67, SD = 12.27). It was used in confirmatory factor analysis. A four-item scale is obtained, having excellent goodness of fit: [χ²/df = .609, GFI (Jöreskog and Sörbom's Goodness-of-Fit Index) = .999, NFI (Normed Fit Index) = .999, CFI (Bentler's Comparative Fit Index) = 1.000, RMSEA (Steiger-Lind root mean square error of approximation) = .000 (90% CI = .0001, .077); SRMR (standardized root mean square residual) = .007], as well as factorial invariance across sexes; the scale has good internal consistency (ω = .869, α = .858, ordinal α = .906). Brief Interactive Optimism Scale-G correlates significantly with self-esteem (r = .779, p < . 01, 95% CI [.816, .736]), depression (r = -.810, p < .01, 95% CI [.843, .772]), and psychopathy (r = -.670, p < . 01, 95% CI [.723, .611]). In conclusion, Brief Interactive Optimism Scale-G is a good option for measuring optimism in Mexicans.

Being Bullied at School: Gratitude as Potential Protective Factor for Suicide Risk in Adolescents

Bullying victimization has been recognized as a risk factor for social, physical, and psychological problems in adolescence. One promising resource that seems to protect adolescents from adversity and traumatic events is gratitude. However, no analysis of the specific role of gratitude in bullying context has been performed as yet. Thus, the aim of this research was to explore the associations between bullying victimization, gratitude and suicide risk (i.e., depressive symptoms and suicidal thoughts and behaviors) and gender-based differences. We also investigated whether levels of gratitude moderated the relationship between victimization and suicide risk for girls and boys. A convenience sample of 1,617 adolescents (50.5% girls; M age = 14.02) participated in this research. Adolescents completed a paper-and-pencil questionnaire about their bullying victimization, gratitude, depressive symptoms and suicidal thoughts and behaviors. Gratitude was found to be negatively related to victimization and suicide risk. While no gender differences were found in gratitude, it was observed that girls reported higher levels of suicide risk. However, the victimization × gratitude interaction contributed to variance in suicide risk, but only for girls: Those girls who were victims of bullying with high gratitude scores reported lower suicide risk than their counterparts who showed less gratitude. Thus, the findings from this present cross-sectional study suggest that gratitude is related to suicide risk in the context of bullying victimization, especially among adolescent girls. Finally, the theoretical and practical implications of our novel contributions to the understanding of gratitude as a protective factor against consequences of bullying victimization are discussed.
