The purpose of this present investigation was to cross-validate a stress-psychosocial vulnerability model of suicidal ideation and behavior in a jail population. Measures of social alienation, cognitive distortions, adaptive resources, situational (jail environment) stress, depression, hopelessness, and suicide ideation were administered to 146 male inmates at a county jail facility. It was predicted that each of the vulnerability factors, in addition to jail stress, would be significantly related to suicide ideation among inmates. Furthermore, it was hypothesized that psychosocial vulnerability among inmates would interact with jail stress to best explain suicide intent. The result of a multiple-regression analysis, stepwise forward-inclusion algorithm, indicated that 51% of the variation in suicide ideation could be accounted for by the linear combination of low reasons for living, irrational beliefs, jail stress, and loneliness. In addition, when the variables were entered into a hierarchical multiple-regression model, interactions between select psychosocial vulnerability factors and jail stress were found to best explain suicide intent. Results of the study are discussed in terms of the proposed model, and implications for future research and prevention efforts in jail suicide are noted.
本研究的目的是在监狱人群中对自杀意念和行为的应激-心理社会脆弱性模型进行交叉验证。对某县监狱设施中的146名男性囚犯进行了社会疏离感、认知扭曲、适应性资源、情境（监狱环境）应激、抑郁、绝望和自杀意念等方面的测量。研究预测，除了监狱应激外，每个脆弱性因素都将与囚犯中的自杀意念显著相关。此外，研究假设囚犯中的心理社会脆弱性将与监狱应激相互作用，以最好地解释自杀意图。多元回归分析的结果，采用逐步向前纳入算法，表明自杀意念变异的51%可由低生存理由、非理性信念、监狱应激和孤独感的线性组合来解释。此外，当将这些变量纳入分层多元回归模型时，发现特定心理社会脆弱性因素与监狱应激之间的相互作用能最好地解释自杀意图。根据所提出的模型对研究结果进行了讨论，并指出了对未来监狱自杀研究和预防工作的启示。
