The interpersonal-psychological theory of suicidal behavior (T. E. Joiner, 2005) proposes that an individual will not die by suicide unless he or she has both the desire to die by suicide and the ability to do so. Three studies test the theory's hypotheses. In Study 1, the interaction of thwarted belongingness and perceived burdensomeness predicted current suicidal ideation. In Study 2, greater levels of acquired capability were found among individuals with greater numbers of past attempts. Results also indicated that painful and provocative experiences significantly predicted acquired capability scores. In Study 3, the interaction of acquired capability and perceived burdensomeness predicted clinician-rated risk for suicidal behavior. Implications for the etiology, assessment, and treatment of suicidal behavior are discussed.
自杀行为的人际心理理论（T.E.乔伊纳，2005年）提出，除非一个人既有自杀的意愿又有自杀的能力，否则他或她不会自杀身亡。三项研究对该理论的假设进行了检验。在研究1中，归属感受挫和感知到的负担感之间的相互作用预测了当前的自杀意念。在研究2中，过去自杀未遂次数较多的个体具有更高水平的习得性能力。结果还表明，痛苦和刺激性经历能显著预测习得性能力得分。在研究3中，习得性能力和感知到的负担感之间的相互作用预测了临床医生评定的自杀行为风险。本文还讨论了这些研究结果对自杀行为的病因、评估和治疗的启示。
