OBJECTIVES In this study, the effectiveness of a couples-based group intervention to prevent intimate partner violence (IPV), Strength at Home Couples (SAH-C), was examined on a military installation relative to a comparison intervention, Supportive Prevention (SP). It was expected that greater reductions in use of physical, psychological, and sexual IPV behaviors, as well as reduced suicidality, would be found among service members and their partners in SAH-C relative to SP. METHOD Participants included 138 couples randomized to SAH-C and SP through a clinical controlled trial embedded in a hybrid effectiveness implementation study which took place on a military installation. The Revised Conflict Tactics Scales and Multidimensional Measure of Emotional Abuse were used to measure IPV, and 13 Military Suicide Research Consortium common data elements were used to assess suicidality. RESULTS Service members randomized to SAH-C evidenced greater reductions based on effect sizes across the assessment time points for all IPV variables, including use of overall physical IPV, severe physical IPV, sexual IPV, psychological IPV, and coercive control IPV relative to those randomized to SP. Partners of service members demonstrated a similar general pattern for reductions in use of IPV, but findings were not as robust as for service members. Both service members and partners demonstrated greater reductions in suicidality based on effect sizes when randomized to SAH-C relative to SP. CONCLUSIONS Findings extend prior work demonstrating the promising effects of SAH-C delivered in the military context and highlight the possible benefits of SAH-C in preventing self-harm thoughts and behaviors.

检查家庭夫妇在军事设施中防止亲密伴侣暴力的力量：一项随机对照试验。


目的 在本研究中，在军事设施中检查了基于夫妻的团体干预措施（预防亲密伴侣暴力（IPV））家庭力量（SAH-C）与比较干预措施（支持性预防（SP））的有效性。 。预计与 SP 相比，SAH-C 中的军人及其伴侣在身体、心理和性方面的 IPV 行为的使用会更大程度地减少，自杀倾向也会减少。方法 参与者包括 138 对夫妇，通过在军事设施中进行的混合有效性实施研究中嵌入的临床对照试验，随机分配至 SAH-C 和 SP。使用修订后的冲突策略量表和情感虐待的多维测量来测量 IPV，并使用 13 个军事自杀研究联盟通用数据元素来评估自杀倾向。结果 随机分配到 SAH-C 的服役人员证明，与随机分组相比，根据所有 IPV 变量在评估时间点上的效应大小，包括整体身体 IPV、严重身体 IPV、性 IPV、心理 IPV 和强制控制 IPV 的使用，有更大的减少到 SP。服役人员的伴侣在减少 IPV 使用方面表现出类似的一般模式，但研究结果并不像服役人员那样稳健。根据效果大小，当随机分配到 SAH-C 组（相对于 SP）时，服役人员和伴侣的自杀率都有更大程度的降低。结论 研究结果扩展了先前的工作，证明了 SAH-C 在军事环境中的良好效果，并强调了 SAH-C 在防止自残想法和行为方面可能带来的好处。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
