This study examined the application of the interpersonal-psychological theory of suicide to community-dwelling older persons in South Korea.
A cross-sectional study design was used. The data were collected by surveying 200 older persons (117 female, 83 male) aged over 65 years at welfare centers for older persons. The Interpersonal Needs Questionnaire, the Suicidal Ideation Scale, and the Acquired Capability for Suicide Scale were used to assess participants' thwarted belongingness, perceived burdensomeness, suicidal ideation, attempts, and the capability for suicide. Structural equation modeling was used to examine the fitness of a model based on the interpersonal-psychological theory of suicide. This theory described that perceived burdensomeness and thwarted belongingness lead to suicidal ideation, which is transformed into suicide attempts through an acquired capability for suicide.
Perceived burdensomeness was significantly associated with suicidal ideation among older persons, whereas thwarted belongingness was not. Furthermore, suicidal ideation influenced suicide attempts. The acquired capability for suicide moderated the relationship between suicidal ideation and suicide attempts.
To prevent suicidal ideation and suicide attempts among older persons, it is important to prevent them from feeling that they are a burden.
本研究旨在将人际心理自杀理论应用于韩国的社区老年人。
采用横断面研究设计。在老年人福利中心调查了 200 名年龄在 65 岁以上的老年人（117 名女性，83 名男性）。采用人际需求问卷、自杀意念量表和获得自杀能力量表评估参与者的归属感受挫、被认为是负担、自杀意念、自杀企图和自杀能力。结构方程模型用于检验基于人际心理自杀理论的模型的拟合度。该理论描述了被认为是负担和归属感受挫会导致自杀意念，而自杀意念通过获得自杀能力转化为自杀企图。
被认为是负担与老年人的自杀意念显著相关，而归属感受挫则没有。此外，自杀意念影响自杀企图。获得自杀能力调节了自杀意念和自杀企图之间的关系。
为了防止老年人出现自杀意念和自杀企图，重要的是要防止他们感到自己是负担。
