The current study explored the differential roles of dimensions of body image (i.e., affective, cognitive, and behavioral) among a sample of 101 young adults (72.3% female, M=19.45; S.D.=1.28) who reported having engaged in non-suicidal self-injury (NSSI), and a matched comparison group of young adults who did not. A mediational model of NSSI was tested, based on the hypothesis that emotion dysregulation would mediate the relationship between dimensions of body image and engagement in NSSI. Preliminary examination of the variables revealed that negative attitudes, suicide-related rumination, and behavioral practices associated with physical appearance significantly differentiated young adults who reported having engaged in NSSI and those who did not, regardless of gender. Path analytic modeling provided partial support for the proposed mediational model, with significant direct and indirect effects between dimensions of body image and NSSI through emotion dysregulation. Discussion focuses on the importance of understanding the differential roles of dimensions of body image and emotion dysregulation as intrapersonal risk factors related to NSSI engagement.
本研究探讨了身体意象（即情感、认知和行为）维度在 101 名年轻成年人样本中的差异作用，其中 72.3%为女性，M=19.45；S.D.=1.28）报告有非自杀性自伤（NSSI）行为，以及一组匹配的没有 NSSI 行为的年轻成年人对照组。基于情绪失调会中介身体意象维度与 NSSI 行为之间的关系的假设，测试了 NSSI 的中介模型。对变量的初步检查表明，无论性别如何，对负面态度、与自杀相关的沉思以及与外表相关的行为实践都能显著区分报告有 NSSI 行为和没有 NSSI 行为的年轻成年人。路径分析模型提供了对拟议中介模型的部分支持，身体意象维度与 NSSI 之间存在显著的直接和间接影响，通过情绪失调。讨论的重点是理解身体意象和情绪失调的维度作为与 NSSI 行为相关的内在风险因素的差异作用的重要性。
