Although existing studies have proved that autistic traits (AT) may have relations to non-suicidal self-injury (NSSI) behaviors, its associations with anxiety, rumination and experiential avoidance (EA) are still unclear. The current study, based on a sample of 1317 Chinese college students, explored the associations between AT, anxiety and NSSI, and the possible modulating roles of rumination and EA in these associations. The results shows that 1) a total of 334 (25.36%) students reported a history of NSSI and 30 (2.28%) students were categorized as high AT; 2) Students with high AT reported higher rates of NSSI than those with low AT (36.67% vs. 25.10%); 3) AT, anxiety, rumination and EA have positive relations with NSSI; 4) AT predicted NSSI indirectly through anxiety; 5) Rumination and EA significantly moderated the effects of AT on NSSI via anxiety. In conclusion, this study confirms the indirect effect of AT on NSSI through anxiety in Chinese college students, and further clarifies the reinforcing effects of rumination and EA on the associations between AT, anxiety and NSSI. These findings suggest that developing adaptive emotion-regulating strategies and positive coping styles might promote the prevention and treatment of NSSI behaviors among autistic individuals.
尽管现有研究已证明自闭症特质（AT）可能与非自杀性自伤（NSSI）行为有关，但其与焦虑、沉思和经验性回避（EA）之间的关联仍不明确。本研究以1317名中国大学生为样本，探讨了AT、焦虑与NSSI之间的关联，以及沉思和EA在这些关联中可能的调节作用。结果显示：1）共有334名（25.36%）学生报告有NSSI史，30名（2.28%）学生被归类为高AT；2）高AT学生的NSSI发生率高于低AT学生（36.67%对25.10%）；3）AT、焦虑、沉思和EA与NSSI呈正相关；4）AT通过焦虑间接预测NSSI；5）沉思和EA显著调节了AT通过焦虑对NSSI的影响。总之，本研究证实了在中国大学生中AT通过焦虑对NSSI的间接影响，并进一步阐明了沉思和EA对AT、焦虑与NSSI之间关联的强化作用。这些发现表明，发展适应性情绪调节策略和积极应对方式可能有助于预防和治疗自闭症个体的NSSI行为。
