Trait anger has been shown to be a predictor of suicide attempts in past studies, with people higher in trait anger having an increased risk of attempting suicide. Nevertheless, the underlying mechanisms as to why this relationship persists are still mostly unknown. The aim of this research was to investigate the prospective relationship between trait anger and suicide attempts. Based on the idea that frequent anger may harm social relationships, we proposed loneliness to mediate the relationship between trait anger and suicide attempts. The study design was longitudinal, and data was collected using ecological momentary assessment over a study period of one year. The sample consisted of participants with a history of suicide attempt or suicidal ideation (N = 65). Survival analysis was used to analyze the data. Against our predictions, higher trait anger was not related to an increased risk of attempting suicide. The hypothesized mediation effect of loneliness was also not significant. Possible reasons for this may be sample characteristics and our operationalizations of trait anger and loneliness. Nevertheless, our findings contribute to the literature on suicide attempts by utilizing comprehensive data collection and analysis methodologies as well as proposing important considerations for future research. Awareness of suicide attempts and corresponding prevention interventions are discussed.Show less

Factors that increase the risk of suicidal ideation in the long-term may differ from factors contributing to present suicidal ideation. The aim of this single-case study was to investigate real-time, concurrent associations between suicidal ideation and perceived burdensomeness, hopelessness, loneliness, optimism, social support, and stress. Data were obtained via ecological momentary assessment with four assessments per day over a 21-day period. It was hypothesised that higher scores of burdensomeness, hopelessness, loneliness, and stress, as well as lower optimism scores and the absence of social support would be associated with concurrent increases in suicidal ideation. Additionally, the role of social support as a potential moderator of the relationships between suicidal ideation and perceived burdensomeness, hopelessness, loneliness, optimism, and stress was examined. A multilevel linear mixed model analysis yielded significant associations between hopelessness, loneliness, and social support with suicidal ideation. Further, social support significantly moderated the association between suicidal ideation and hopelessness, with both being lower when the participant was in company. These results imply that repeated daily assessments of hopelessness, loneliness, and social support in individuals at suicide risk may be used as indicators of the severity of current suicidal ideation. Besides, social support may serve as a protective factor that could be integrated in suicide prevention strategies. Nonetheless, these conclusions are limited in their external validity given the case-study design. Further research replicating this study with a larger sample is needed to obtain generalisable conclusions.Show less
