BackgroundIn the UK, around one-third of young people are exposed to Intimate Partner Violence and Abuse (IPVA) by 21 years old. However, types of IPVA victimization in this population (psychological, physical, sexual), and their relationship with impact and perpetration are poorly understood.MethodsParticipants in a UK birth cohort reported IPVA victimization and perpetration by age 21. We carried out a latent class analysis, where we categorized IPVA by types/frequency of victimization, and then assigned individuals to their most probable class. Within these classes, we then estimated rates of reported: 1) types of negative impacts (sad, upset/unhappy, anxious, depressed, affected work/studies, angry/annoyed, drank/took drugs more); 2) types/frequency of perpetration.ResultsAmong 2130 women and 1149 men, 32% and 24% reported IPVA victimization (of which 89% and 73% reported negative impact); 21% and 16% perpetration. Victimization responses were well represented by five classes, including three apparent in both sexes: No-low victimization (characterized by low probabilities of all types of victimization; average probabilities of women and men belonging to this class were 82% and 70%); Mainly psychological (15% and 12%); Psychological and physical victimization (4% and 7%), and two classes that were specific to women: Psychological and sexual (7%); Multi-victimization (frequent victimization for all three types; 4%). In women, all types of negative impact were most common in the Psychological and sexual and Multi-victimization classes; for men, the Psychological and physical class. In women, all types of perpetration were most common for the Mainly psychological, Psychological and physical and Multi-victimization classes; in men, the Mainly psychological and Psychological and physical classes.DiscussionIn this study of young people, we found categories of co-occurrence of types and frequency of IPVA victimization associated with differential rates of negative impact and perpetrating IPVA. This is consistent with emerging evidence of IPVA differentiation and its variable impact in other populations.

年轻女性和男性中亲密伴侣暴力和虐待的类别：英国出生队列中心理、身体和性受害和犯罪的潜在类别分析


背景在英国，大约三分之一的年轻人在 21 岁时遭受过亲密伴侣暴力和虐待 (IPVA)。然而，人们对这一人群中 IPVA 受害类型（心理、身体、性）及其与影响和犯罪的关系知之甚少。方法英国出生队列的参与者报告了 21 岁时的 IPVA 受害和犯罪行为。我们进行了潜在类别分析，我们根据受害类型/频率对 IPVA 进行分类，然后将个人分配到最可能的类别。然后，在这些类别中，我们估计了报告的比率：1）负面影响的类型（悲伤、心烦意乱/不快乐、焦虑、抑郁、影响工作/学习、生气/恼火、喝酒/吸毒更多）； 2) 犯罪的类型/频率。结果在 2130 名女性和 1149 名男性中，32% 和 24% 的人报告了 IPVA 受害情况（其中 89% 和 73% 的人报告了负面影响）； 21％和16％的犯罪。受害反应由五个类别很好地代表，其中三个类别在男女中均明显：非低受害（其特征是所有类型受害的概率较低；女性和男性属于该类别的平均概率分别为 82% 和 70%）；主要是心理上的（15%和12%）；心理和身体受害（4％和7％），以及针对女性的两类：心理和性（7％）；多重受害（所有三种类型均频繁受害；4%）。在女性中，所有类型的负面影响在心理、性和多重受害类别中最为常见；对于男性来说，心理和身体课程。 在女性中，所有类型的犯罪行为在主要心理类、心理和身体类以及多重受害类中最为常见；在男性中，主要是心理和心理和身体类别。讨论在这项针对年轻人的研究中，我们发现IPVA受害类型和频率的共现类别与负面影响和实施IPVA的不同比率相关。这与 IPVA 分化及其对其他人群的不同影响的新证据是一致的。
