Research has demonstrated that a lack of social support is related to suicide risk. This study examines perceived burdensomeness and thwarted belongingness, of the Interpersonal Theory of Suicide, as mechanisms of the social support-suicide relationship in college students.
The study consisted of 207 students from a Midwestern university. Data were collected from 2007 to 2008. Two multiple mediation analyses were conducted to examine whether perceived burdensomeness and thwarted belongingness mediated the relationship between indices of social support and suicide ideation.
Perceived burdensomeness mediated the relationships between perceived social support and suicide ideation (95% confidence interval [CI] -.02 to -.00, effect size = -.01) and social connectedness and suicide ideation (95% CI -.03 to -.00, effect size = -.03). Thwarted belongingness did not mediate either relationship.
Results suggest that a lack of social support could lead to perceptions of being a burden on others, which could lead to suicide ideation.
研究表明，缺乏社会支持与自杀风险相关。本研究考察自杀人际理论中的自我感知负担和归属感 thwarted belongingness，作为大学生社会支持与自杀关系的机制。
该研究由一所中西部大学的207名学生组成。数据收集于2007年至2008年。进行了两项多重中介分析，以检验自我感知负担和归属感 thwarted belongingness 是否介导了社会支持指标与自杀意念之间的关系。
自我感知负担介导了感知到的社会支持与自杀意念之间的关系（95%置信区间[CI] -0.02至-0.00，效应大小 = -0.01）以及社会联结与自杀意念之间的关系（95% CI -0.03至-0.00，效应大小 = -0.03）。归属感 thwarted belongingness 未介导任何一种关系。
结果表明，缺乏社会支持可能导致个体认为自己成为他人的负担，进而可能导致自杀意念。
