自杀的人际心理理论（IPTS）得到了最近研究的支持。然而，该模型的三个主要结构的性质-感知负担，挫败的能力和获得的能力-需要进一步的调查。在本文中，我们测试了一些假设的预测和相关的IPTS结构。对来自澳大利亚基于人群的纵向队列研究（n=1167）的32-38岁的参与者进行了评估。IPTS结构的测量项目从人际需求问卷（INQ）和获得的自杀能力量表（ACSS），以及人口统计学和其他措施，同时或约8年前测量。评估IPTS的横截面分析支持了早期的工作。心理健康是显着相关的所有三个IPTS结构，但抑郁和焦虑的情况下，只与感知负担。不同的社会支持措施与三个结构。应激事件和终身创伤与获得性自杀能力之间存在强有力的独立关联。IPTS模型为自杀风险的概念化提供了一个有用的框架。研究结果强调了感知社会支持在自杀风险中的重要性，确定了人格和其他因素作为研究新途径的重要性，并为结构的独立性提供了一些验证。(C)2014爱思唯尔爱尔兰有限公司版权所有。
The Interpersonal-Psychological Theory of Suicide (IPTS) has been supported by recent research. However, the nature of the models' three major constructs - perceived burdensomeness, thwarted belongingness and acquired capability - requires further investigation. In this paper, we test a number of hypotheses about the predictors and correlates of the IPTS constructs. Participants aged 32-38 from an Australian population-based longitudinal cohort study (n=1167) were assessed. IPTS constructs were measured by items from the Interpersonal Needs Questionnaire (INQ) and Acquired Capability for Suicide Scale (ACSS), alongside demographic and additional measures, measured concurrently or approximately 8 years earlier. Cross-sectional analyses evaluating the IPTS supported earlier work. Mental health was significantly related to all three IPTS constructs, but depression and anxiety caseness were associated only with perceived burdensomeness. Various social support measures were differentially associated with the three constructs. Stressful events and lifetime traumas had robust independent associations with acquired capability for suicide only. The IPTS model provides a useful framework for conceptualising suicide risk. The findings highlight the importance of perceived social support in suicide risk, identify the importance of personality and other factors as new avenues of research, and provide some validation for the independence of the constructs.
