Posttraumatic stress symptoms (PTSS) are associated with both childhood physical abuse (CPA) and antisocial (AS) traits, yet their potential as mediators of the CPA-AS traits link is understudied and the specific roles of individual symptom clusters in this relation is unknown. The current study aimed to examine the mediational role of PTSS in the relation between CPA and AS traits in a sample of low-income African American women with histories of intimate partner violence (IPV). It was hypothesized that avoidance would emerge as a significant mediator, whereas reexperiencing, numbing, and hyperarousal would not. Participants (N = 150) were recruited from a level-1 trauma public hospital and evaluated as part of a randomized controlled trial of a group therapy intervention for low-income, African American women suicide attempters with histories of IPV. The Childhood Trauma Questionnaire (CTQ), Posttraumatic Diagnostic Scale (PDS), and International Personality Disorder Examination-Screening Questionnaire (IPDE-SQ) were used to measure variables of interest. Using bootstrapping analyses, a parallel mediation model compared PTSS clusters as potential mediators of the CPA-AS traits relation, controlling for IPV. When reexperiencing, avoidance, numbing, and hyperarousal were entered simultaneously as potential mediators, only avoidance emerged as a significant mediator of the CPA-AS traits link. Avoidance symptoms may play a unique role in the link between early experiences of CPA and later AS traits among multiply traumatized African American women. Findings have implications for understanding AS traits in the context of early life trauma and suggest that targeting specific PTSS clusters (e.g., avoidance) may improve treatment outcomes for women in this population.

创伤后应激症状 (PTSS) 与儿童身体虐待 (CPA) 和反社会 (AS) 特征有关，但它们作为 CPA-AS 特征联系的中介的潜力尚未得到充分研究，并且个体症状群在这种关系中的具体作用尚不清楚. 目前的研究旨在检验 PTSS 在 CPA 和 AS 特征之间关系中的中介作用，样本是有亲密伴侣暴力 (IPV) 史的低收入非洲裔美国女性。据推测，回避会成为一个重要的中介，而重新体验、麻木和过度唤醒则不会。参与者（N = 150) 从 1 级创伤公立医院招募，并作为针对具有 IPV 历史的低收入非裔美国女性自杀未遂者的随机对照试验的一部分进行评估。童年创伤问卷(CTQ)、创伤后诊断量表 (PDS) 和国际人格障碍检查筛查问卷 (IPDE-SQ) 用于测量感兴趣的变量。使用引导分析，平行中介模型将 PTSS 集群作为 CPA-AS 特征关系的潜在中介进行比较，控制 IPV。当重新体验、回避、麻木和过度觉醒作为潜在中介同时输入时，只有回避成为 CPA-AS 特征链接的重要中介。回避症状可能在 CPA 的早期经历与受多重创伤的非洲裔美国女性后来的 AS 特征之间的联系中发挥独特的作用。研究结果对理解早年创伤背景下的 AS 特征具有重要意义，并表明针对特定的 PTSS 群（例如，
