ABSTRACT Childhood maltreatment increases the risk of peer victimization in middle school students, yet the specific link between them remains unclear. This study used latent profile analysis (LPA) to identify maltreatment subtypes and examined how coping strategies moderated their relationship with different types of peer victimization, comparing these effects across family structures. A total of 1011 7th-grade Chinese students (M[subscript age] = 11.97; SD[subscript age] = 0.4) participated in the current study and were measured through "Childhood Trauma Questionnaire, Coping Style Scale for Middle School Students and Delaware Bullying Victimization Scale-Student Chinese Version." Three distinct maltreatment profiles were identified: low maltreatment (84.4%), psychological maltreatment (12.5%), and multi-type maltreatment (3.2%). Problem-focused coping moderated the effects depending on the profile, while emotion-focused coping consistently worsened outcomes. Students from intact families experienced less peer victimization and showed different patterns in how problem-focused coping related to verbal victimization. These findings underscore the role of coping strategies in reducing the impact of childhood maltreatment on peer victimization.
