Intimate partner violence (IPV) is a serious public health concern worldwide and defined as behavior performed by spouses or other intimate partners that causes physical, sexual, or psychological harm. Internet-delivered cognitive-behavioral therapy (ICBT) may be particularly useful for survivors of IPV for several reasons, including barriers pertaining to limited community recourses and treatment availability, safety concerns, and issues of stigma, guilt and shame, which may prevent members of this population from seeking help via face-to-face interactions. However, Internet interventions are lacking. The primary aim of the present randomized controlled pilot trial was to explore the feasibility of ICBT as guided self-help individually tailored to the predominant symptomatology of PTSD or depression in survivors of IPV. A second aim was to conduct a preliminary evaluation exploring the short- and long-term effects of the treatment in comparison to a waitlist control condition. Results showed that the treatment was feasible. Attrition rate was low (9.4%), and participants were satisfied with treatment. However, treatment adherence was moderate in terms of completed modules (62.5%). Results of the preliminary evaluation of treatment effects showed large and statistically significant between-group effect sizes (Cohen's d = 0.86–1.08) on some measures of PTSD and depression at post assessment, favoring the treatment condition. However, there were no effects on other measures. At follow-up assessment, when the control condition had received delayed treatment, there were large and statistically significant within-group effect sizes (d = 0.96–1.48) on measures of PTSD, depression and anxiety, and small effects (d = 0.48) on a measure of quality of life. The results of the present pilot study are promising and warrant further research on ICBT for this population.

亲密伴侣暴力 (IPV) 是世界范围内严重的公共卫生问题，被定义为配偶或其他亲密伴侣所进行的导致身体、性或心理伤害的行为。互联网提供的认知行为疗法 (ICBT) 可能对 IPV 幸存者特别有用，原因有几个，包括与有限的社区资源和治疗可用性、安全问题以及污名、内疚和羞耻问题有关的障碍，这可能会阻止这些人通过面对面的互动寻求帮助。然而，缺乏互联网干预。本随机对照试验的主要目的是探索 ICBT 作为指导性自助的可行性，针对 IPV 幸存者的 PTSD 或抑郁症的主要症状进行个性化定制。第二个目的是进行初步评估，探索治疗与候补控制条件相比的短期和长期影响。结果表明治疗是可行的。流失率低 (9.4%)，参与者对治疗感到满意。然而，就完成的模块而言，治疗依从性中等（62.5%）。治疗效果的初步评估结果显示组间效应量大且具有统计学意义（Cohen'sd  = 0.86–1.08) 在评估后的一些 PTSD 和抑郁症指标上，有利于治疗条件。但是，对其他措施没有影响。在后续评估中，当对照条件接受延迟治疗时，在 PTSD、抑郁和焦虑的测量方面存在较大且具有统计学意义的组内效应大小 ( d = 0.96–1.48)，以及较小的效应 ( d  = 0.48)在生活质量的衡量标准上。本试点研究的结果很有希望，值得进一步研究针对该人群的 ICBT。
