Dropout in perpetrator intervention programs (PIPs) is extensively documented in the literature, yet findings across various studies exhibit global inconsistency. This meta-analysis aimed to identify dropout rates among individuals attending PIPs and examine sociodemographic, violence-related, intrapersonal, interpersonal, and external variables related to dropout. A search was conducted across six databases, encompassing studies published between 2010 and 2022 in English, Spanish, or Portuguese. Thirty manuscripts, comprising data from 31 independent samples, were included. Dropout rates varied from 9% to 67%. Bivariate analysis results indicated that younger age ( OR = 0.69), non-White ethnicity ( OR = 1.54), unemployment ( OR = 1.78), offender typology other than family only ( OR = 2.45), substance abuse ( OR = 1.78), presenting a personality disorder ( OR = 1.21), engaging in problematic leisure activities ( OR = 1.28), possessing a greater criminal history ( OR = 1.47), and experiencing more adversity in childhood ( OR = 1.44) were significantly correlated with dropout. Additionally, the inclusion of motivational strategies in treatment ( OR = 0.44) significantly decreased the likelihood of dropout. Results from multivariate analyses revealed that younger age ( OR = 0.63), presenting a personality disorder ( OR = 1.73), and experiencing more adversity in childhood ( OR = 2.16) were significantly associated with dropout. Notably, intimate partner violence characteristics established a significant negative relation with dropout ( OR = 0.59). Findings indicate that variables associated with dropout align with those related to general and intimate partner violence recidivism, suggesting that individuals requiring more intensive intervention are those who derive less benefit from it.

亲密伴侣暴力施暴者的干预计划退出：相关变量的荟萃分析

文献中广泛记录了肇事者干预计划（PIP）中的退出情况，但各种研究的结果显示全球不一致。这项荟萃分析旨在确定参加 PIP 的个人的辍学率，并检查与辍学相关的社会人口、暴力相关、个人内部、人际和外部变量。对六个数据库进行了检索，其中包括 2010 年至 2022 年以英语、西班牙语或葡萄牙语发表的研究。其中包括 30 份手稿，其中包含来自 31 个独立样本的数据。辍学率从 9% 到 67% 不等。双变量分析结果表明，年龄较小（OR = 0.69）、非白人（OR = 1.54）、失业（OR = 1.78）、仅家庭以外的犯罪类型（OR = 2.45）、药物滥用（OR = 1.78）、存在人格障碍（OR = 1.21）、从事有问题的休闲活动（OR = 1.28）、有较多犯罪史（OR = 1.47）以及在童年经历更多逆境（OR = 1.44）与辍学显着相关。此外，在治疗中纳入激励策略（OR = 0.44）显着降低了退出的可能性。多变量分析结果显示，年龄较小（OR = 0.63）、存在人格障碍（OR = 1.73）和童年经历更多逆境（OR = 2.16）与辍学显着相关。值得注意的是，亲密伴侣暴力特征与辍学率呈显着负相关（OR = 0.59）。研究结果表明，与辍学相关的变量与一般和亲密伴侣暴力累犯相关的变量一致，这表明需要更强化干预的个人是那些从中受益较少的人。
