Childhood sexual abuse (CSA) and bullying victimization are well-established risk factors for deliberate self-harm (DSH) and suicidal ideation (SI). Research ties aspects of self-concept, such as self-esteem, with victimization and self-harm. Yet, there is limited evidence of the role of multidimensional self-concept in the victimization-self-harm association. Using a longitudinal sample of 422 adolescent girls from a large midwestern city, 35% with recently substantiated CSA-exposure and 51% with recent bullying victimization at baseline, we examined pathways from CSA-exposure and bullying victimization to subsequent DSH and SI, with global self-worth and five subscales of self-concept as mediators (social competence, close friendships, physical appearance, scholastic competence, and behavioral conduct). Data was collected from 2012 to 2015. CSA-exposure directly increased the risk of both SI (B .50, SE .23, p < .05) and DSH (B .53, SE .22, p < 5), while global self-worth fully mediated the relationship between bullying victimization, SI (B .21, SE .07, 95% BCB-CI 1.17–1.95, p < .01), and DSH (B .15, SE .06, 95% BCB-CI 1.10–1.69, p < .05), We found no evidence of mediation for the subscales model. Both CSA-exposure and bullying victimization directly reduced specific subscales of self-concept, while behavioral conduct increased the risk of DSH. The role of self-concept in the bullying/self-harm association and the direct effects of CSA-exposure on self-harm highlight areas of need in social work practice, specifically the need to incorporate an emphasis on trusting relationships, overall well-being, and the reduction of shame into trauma-informed therapy and bullying prevention efforts.

童年性虐待（CSA）和欺凌受害是故意自残（DSH）和自杀意念（SI）的明确风险因素。研究将自我概念的各个方面（例如自尊）与受害和自残联系起来。然而，多维自我概念在受害-自残关联中的作用的证据有限。我们对来自中西部大城市的 422 名青春期女孩进行了纵向样本分析，其中 35% 的女孩最近经历过 CSA 暴露，51% 的女孩最近在基线上遭受过欺凌，我们研究了从 CSA 暴露和欺凌受害到随后的 DSH 和 SI 的路径，自我价值和自我概念的五个子量表作为中介（社交能力、亲密友谊、外表、学业能力和行为行为）。数据收集于 2012 年至 2015 年。CSA 暴露直接增加 SI ( B .50, SE .23, p < .05) 和 DSH ( B .53, SE .22, p < 5)的风险，而全球范围内自我价值完全调节欺凌受害、SI ( B .21, SE .07, 95% BCB-CI 1.17–1.95, p < .01) 和 DSH ( B .15, SE .06, 95% BCB)之间的关系-CI 1.10–1.69，p < .05），我们没有发现子量表模型中介的证据。 CSA暴露和欺凌受害都直接降低了自我概念的特定分量表，而行为行为则增加了DSH的风险。自我概念在欺凌/自残关联中的作用以及 CSA 暴露对自残的直接影响突出了社会工作实践中的需要领域，特别是需要强调信任关系、整体福祉，并将羞耻感减少到创伤知情治疗和欺凌预防工作中。
