In recent years, major global institutions have amplified their efforts to address intimate partner violence (IPV) against women-a global health and human rights violation affecting 15-71% of reproductive aged women over their lifetimes. Still, some scholars remain concerned about the validity of instruments used for IPV assessment in population-based studies. In this paper, we conducted two validation analyses using novel data from 450 women-men dyads across nine villages in Northern Tanzania. First, we examined the level of inter-partner agreement in reporting of men's physical, sexual, emotional and economic IPV against women in the last three and twelve months prior to the survey, ever in the relationship, and during pregnancy. Second, we conducted a convergent validity analysis to compare the relative efficacy of men's self-reports of perpetration and women's of victimization as a valid indicator of IPV against Tanzanian women using logistic regression models with village-level clustered errors. We found that, for every violence type across the recall periods of the last three months, the last twelve months and ever in the relationship, at least one in three couples disagreed about IPV occurrences in the relationship. Couples' agreement about physical, sexual and economic IPV during pregnancy was high with 86-93% of couples reporting concordantly. Also, men's self-reported perpetration had statistically significant associations with at least as many validated risk factors as had women's self-reported victimization. This finding suggests that men's self-reports are at least as valid as women's as an indicator of IPV against women in Northern Tanzania. We recommend more validation studies are conducted in low-income countries, and that data on relationship factors affecting IPV reports and reporting are made available along with data on IPV occurrences.
近年来，主要的全球机构加大了力度，以解决针对妇女的亲密伴侣暴力（IPV）问题——这是一种影响全球范围内 15-71%育龄妇女的健康和人权侵犯。尽管如此，一些学者仍然对基于人群的研究中用于 IPV 评估的工具的有效性表示关注。在本文中，我们使用来自坦桑尼亚北部九个村庄的 450 名女性-男性对偶的数据进行了两项验证分析。首先，我们检查了报告的男性在过去三个月和十二个月前，在关系中以及怀孕期间对女性的身体、性、情感和经济 IPV 的伴侣间一致性程度。其次，我们进行了一项收敛有效性分析，以比较男性自报的施暴行为和女性自报的受害行为作为坦桑尼亚女性 IPV 的有效指标的相对效力，使用带有村级聚类误差的逻辑回归模型。我们发现，对于每一种暴力类型，在过去三个月、过去十二个月和关系中，至少三分之一的夫妇对关系中发生的暴力事件存在分歧。夫妇对怀孕期间的身体、性和经济 IPV 的一致性很高，有 86-93%的夫妇报告一致。此外，男性的自报施暴行为与至少与女性的自报受害行为一样，与许多验证过的风险因素存在统计学显著关联。这一发现表明，在坦桑尼亚北部，男性的自报与女性的自报一样，至少是作为女性遭受 IPV 的一个有效指标。我们建议在低收入国家进行更多的验证研究，并提供关于影响 IPV 报告和报告的关系因素的数据，以及关于 IPV 发生情况的数据。
