Joiner's (2005) theory attributes suicide to an individual's acquired capability to enact self-harm, perceived burdensomeness, and thwarted belongingness. This study evaluated whether Joiner's theory could differentiate United States (US) Air Force (AF) personnel (n = 60) who died by suicide from a living active duty AF personnel comparison sample (n = 122). Responses from AF personnel on several scales assessing Joiner's constructs were compared to data from a random sample of postmortem investigatory files of AF personnel who died by suicide between 1996-2006. This research also introduced a newly designed measure, the Interpersonal-Psychological Survey (IPS), designed to assess the three components of Joiner's theory in one, easy-to-administer instrument. Analyses of the psychometric properties of the IPS support initial validation efforts to establish this scale as a predictive measure for suicide. Findings support that one's score on the Acquired Capability to Commit Suicide subscale of the IPS and the IPS overall score reliably distinguished between the two groups. The implications of these findings in relation to suicide prevention efforts in the US military are discussed.
乔伊纳（2005年）的理论将自杀归因于个体获得的自我伤害能力、感知到的负担感和归属感缺失。本研究评估了乔伊纳的理论能否区分美国空军中自杀身亡的人员（n = 60）和现役空军人员组成的对照样本（n = 122）。将空军人员在评估乔伊纳理论结构的几个量表上的回答，与1996年至2006年间自杀身亡的空军人员尸检调查档案随机样本中的数据进行了比较。本研究还引入了一种新设计的测量工具，即人际心理调查（IPS），旨在用一种易于实施的工具评估乔伊纳理论的三个组成部分。对IPS心理测量特性的分析支持了将该量表确立为自杀预测指标的初步验证工作。研究结果表明，IPS的自杀获得能力子量表得分和IPS总分能够可靠地区分这两组人员。文中讨论了这些研究结果对美国军队自杀预防工作的意义。
