Intimate partner violence (IPV) is a common, costly societal problem. Interventions designed to reduce IPV recidivism have had limited success but primary prevention efforts are likely to be more effective in reducing the occurrence of IPV. The purpose of this study was to examine the impact of a computer-based preventive intervention (ePREP) on IPV in a sample of married, community couples.
We employed a randomized clinical trial design comparing ePREP to an active placebo control group. Using a community sample of 52 married couples (21% Black, 3% Asian, 65% White, 7% Latino, 4% Mixed/biracial) who had been married, on average, 4.3 years, we examined the impact ePREP on IPV as measured by self and partner reports of the Revised Conflict Tactics Scale. We assessed couples at baseline, six-weeks post-baseline, and one-year post-baseline. We used the Actor Partner Interdependence Model with treatment effects to analyze the obtained dyadic data.
We found that ePREP reduced physical and psychological aggression among married couples (on average across informants, a 90% reduction in expected counts of physical aggression, and a 0.18 standard deviation reduction in psychological aggression) and that these gains were maintained at a 1-year follow-up assessment.
Interventions that can be delivered widely and at a low-cost will increase the likelihood of reaching those who will benefit most from receiving them. Implications for implementing flexible interventions and changing our approach to treatment delivery are discussed.
亲密伴侣暴力（IPV）是一个普遍存在且代价高昂的社会问题。旨在减少 IPV 再犯率的干预措施收效甚微，但初级预防措施可能更有效地减少 IPV 的发生。本研究旨在调查基于计算机的预防干预（ePREP）对已婚社区夫妇中 IPV 的影响。
我们采用随机临床试验设计，将 ePREP 与积极的安慰剂对照组进行比较。使用一个由 52 对已婚夫妇（21%黑人、3%亚裔、65%白人、7%拉丁裔、4%混血/多种族）组成的社区样本，他们的平均婚姻年限为 4.3 年，我们通过自我报告和伴侣报告的修订冲突策略量表来评估 ePREP 对 IPV 的影响。我们在基线、基线后六周和基线后一年评估夫妇。我们使用演员-伙伴相互依存模型和治疗效果来分析获得的对偶数据。
我们发现 ePREP 减少了已婚夫妇的身体和心理攻击（平均而言，在所有信息来源中，身体攻击的预期计数减少了 90%，心理攻击减少了 0.18 个标准差），并且这些收益在 1 年的随访评估中得以维持。
可以广泛且低成本地提供的干预措施将增加接触到最受益于接受干预措施的人的可能性。讨论了实施灵活干预措施和改变我们的治疗提供方式的意义。
