The interpersonal-psychological theory of suicidal behavior posits that 2 proximal, causal, and interactive risk factors must be present for someone to desire suicide: perceived burdensomeness and thwarted belongingness. The purpose of the present study was to evaluate the predictive power of these 2 risk factors in a prospective study.
A total of 231 adult outpatients (age: mean = 38.1, standard deviation = 12.3) undergoing cognitive-behavioral therapy took part in a pretreatment and a midtreatment assessment after the 10th therapy session.
Perceived burdensomeness, thwarted belongingness, and the interaction between these 2 risk factors did not add incremental variance to the prediction of midtreatment suicide ideation after controlling for age, gender, depression, hopelessness, impulsivity, lifetime suicide attempts, and pretreatment suicide ideation. The best predictor of midtreatment suicide ideation was pretreatment suicide ideation.
Results offer only limited support to the assumptions of the interpersonal theory of suicide.
自杀行为的人际心理理论认为，一个人若想自杀，必须同时存在两个直接、具有因果关系且相互作用的风险因素：感知到成为他人负担和归属感受挫。本研究的目的是在前瞻性研究中评估这两个风险因素的预测能力。
共有231名接受认知行为疗法的成年门诊患者（年龄：平均 = 38.1，标准差 = 12.3）在第10次治疗 session 后参与了治疗前和治疗中期评估。
在控制了年龄、性别、抑郁、绝望、冲动性、终生自杀未遂史和治疗前自杀意念后，感知到成为他人负担、归属感受挫以及这两个风险因素之间的相互作用，并未为治疗中期自杀意念的预测增加额外的方差。治疗中期自杀意念的最佳预测指标是治疗前自杀意念。
研究结果仅为自杀人际理论的假设提供了有限的支持。
