This study explores treating violence against others as a precursor to self-directed violence. It tests the utility of including violence against others in the measure of acquired capability to test assumptions from the interpersonal theory of violence. Four theoretical hypotheses are assessed that are consistent with the theory: (1) thwarted belongingness (parental abandonment and rejection) and perceived burdensomeness (exposure to parental interpersonal violence and child abuse) independently increase the likelihood of suicidal ideation; (2) the interaction of thwarted belongingness and perceived burdensomeness increases the likelihood of suicidal ideation controlling for other pertinent variables; (3) the three-way interaction of thwarted belongingness, perceived burdensomeness, and acquired capability (violence against others and prior suicidal attempts) increases the likelihood of suicidal attempts controlling for other pertinent variables; and (4) self-harm responds to the theoretical variables and similarly, to attempts. Subjects are court-adjudicated males (ages 13–18) who were residents for up to 1 year at the Ocean Tides School and rehabilitation center from 1975–2019. The data span 44 years and include 2195 youth. Depression, drug/alcohol use, race, ethnicity, socioeconomic status, and interaction terms between SES and race and SES and ethnicity are also examined. Backward conditional logistic regression analyses find mixed support for the hypotheses, but strong support for including violence against others in the concept of acquired capability. Support is also found for conceptualizing child abuse and exposure to parental interpersonal violence as perceived burdensomeness in tests of this theory as well as measures of depression. Major implications for programming in the treatment and rehabilitation of delinquent boys include conceptualizing and approaching violence against others as a precursor to suicidal attempts and other self-directed harm.

本研究探讨将针对他人的暴力行为视为自我施暴的先兆。它测试了将对他人的暴力纳入衡量后天能力的效用，以测试人际暴力理论的假设。评估了与该理论一致的四个理论假设：（1）挫败的归属感（父母遗弃和拒绝）和感知负担（暴露于父母人际暴力和虐待儿童）独立增加自杀意念的可能性；(2) 受挫的归属感和感知的负担的相互作用增加了控制其他相关变量的自杀意念的可能性；(3) 受挫归属感、感知负担的三向交互作用，获得的能力（对他人的暴力行为和先前的自杀企图）增加了控制其他相关变量的自杀企图的可能性；(4) 自我伤害对理论变量有反应，类似地，对尝试有反应。受试者是法院裁定的男性（13-18 岁），他们在 1975-2019 年期间在海潮学校和康复中心居住了长达 1 年。数据跨越 44 年，包括 2195 名青年。抑郁症、药物/酒精使用、种族、民族、社会经济地位，以及社会经济地位与种族以及社会经济地位与民族之间的相互作用项也被检查。向后条件逻辑回归分析发现对假设的混合支持，但强烈支持将对他人的暴力纳入获得能力的概念。还发现支持将虐待儿童和接触父母人际暴力概念化为对该理论和抑郁症测试的感知负担。对犯罪男孩的治疗和康复规划的主要影响包括将针对他人的暴力行为概念化和处理为自杀企图和其他自我导向伤害的先兆。
