Prior work suggests that an unstable identity is an important developmental factor impacting risk for non-suicidal self-injury (NSSI), partly because it can foster lowered self-esteem and self-blame coping styles. Theoretical models suggest that how one regards the self, including experiences of and reactions to one's body (e.g., body regard), impact how factors such as identity instability and coping styles influence NSSI behavior. This study tested whether body regard moderated the mediational effect of self-blame coping on the relationship between poor self-concept clarity and past-year NSSI.
A sample of 1906 university students had complete data from an anonymous online questionnaires measuring self-concept clarity, self-blame coping, and past-year NSSI behaviors.
Past-year NSSI was reported by 23.5% of the sample. Moderated mediational regression analyses using the PROCESS macro for SPSS were run. Body regard significantly moderated the effects of self-blame coping and poor self-concept clarity on NSSI such that neither risk factor was associated with NSSI when body regard was high. Poor self-concept clarity also retained a significant, although weakened, direct relationship with NSSI in the full model.
Positive body regard is protective and appears to mitigate the strength of the relationships between poor self-concept clarity and self-blame coping on past year NSSI. When body regard is low or average, poor self-concept clarity is associated with increased NSSI, partly through the effect of self-blame coping. Treatments that address body- and self-perceptions related to self-concept may enhance the effectiveness of interventions used to reduce NSSI behavior.
先前的研究表明，不稳定的身份认同是影响非自杀性自伤（NSSI）风险的一个重要发展因素，部分原因是它会助长自尊心降低和自责应对方式。理论模型表明，一个人如何看待自己，包括对自己身体的体验和反应（例如，身体观），会影响身份认同不稳定和应对方式等因素如何影响 NSSI 行为。本研究检验了身体观是否调节了自责应对在自我概念清晰度差与过去一年 NSSI 之间的关系中的中介作用。
一项对 1906 名大学生的匿名在线问卷的研究，问卷测量了自我概念清晰度、自责应对和过去一年的 NSSI 行为。
样本中有 23.5%的人报告过去一年有过 NSSI。使用 SPSS 的 PROCESS 宏进行了调节中介回归分析。身体观显著调节了自责应对和自我概念清晰度对 NSSI 的影响，当身体观较高时，这两个风险因素都与 NSSI 无关。在完整模型中，自我概念清晰度较差也与 NSSI 存在显著但较弱的直接关系。
积极的身体观具有保护作用，似乎可以减轻自我概念清晰度差和自责应对与过去一年 NSSI 之间关系的强度。当身体观较低或中等时，自我概念清晰度差与 NSSI 增加有关，部分原因是自责应对的影响。针对与自我概念相关的身体和自我认知的治疗方法可能会提高用于减少 NSSI 行为的干预措施的有效性。
