The Interpersonal Theory of Suicide has been foundational in guiding current suicide literature. Despite recent research underscoring fluctuations of suicidal ideation within hours, there have been few studies examining the key constructs of perceived burdensomeness and thwarted belongingness within an intensive framework. Thus, the current study aimed to add cumulative knowledge regarding the within-person relationship between perceived burdensomeness, thwarted belongingness, and active suicidal ideation as assessed within an ecological momentary assessment design.
A final sample of 35 individuals with a past-year history of suicidal thoughts or behaviors completed brief surveys four times per day for 30 days.
Findings highlighted that the addition of covariates may offer small improvements in modeling subsequent suicidal ideation, while controlling for SI at the prior time. Further, both thwarted belongingness and perceived burdensomeness were associated with next timepoint suicidal ideation, and their interaction added little incremental value.
Findings demonstrate the potential importance of thwarted belongingness in predicting suicidal ideation. Further, results highlight that the main effects of thwarted belongingness and perceived burdensomeness, rather than their interaction, may be more important to consider in relation to active suicidal ideation.
自杀人际理论一直是指导当前自杀文献的基础。尽管最近的研究强调了数小时内自杀意念的波动，但很少有研究在密集框架内考察感知负担和归属感受挫这些关键构念。因此，本研究旨在增加关于在生态瞬时评估设计中所评估的感知负担、归属感受挫与主动自杀意念之间个体内关系的累积知识。
最终样本包括35名在过去一年中有自杀想法或行为史的个体，他们在30天内每天完成4次简短调查。
研究结果突出表明，在控制先前时间点的自杀意念的同时，加入协变量可能会在对后续自杀意念建模方面带来小幅改进。此外，归属感受挫和感知负担均与下一个时间点的自杀意念相关，且它们的交互作用几乎没有增加额外价值。
研究结果证明了归属感受挫在预测自杀意念方面的潜在重要性。此外，结果突出表明，就主动自杀意念而言，归属感受挫和感知负担的主效应而非它们的交互作用可能更值得考虑。
