非自杀性自伤行为(non-suicidal self-injury,NSSI)主要开始于青少年期,与不良的心理健康问题存在关联性。来自澳大利亚的研究者Tatnell等开展了一项为期12个月的队列研究,探讨个体因素(认知重评、自我效能感、自尊)和人际因素(依恋、社会支持)在NSSI行为中的作用。该研究在澳大利亚40所中学选取2 637名学生(1 793名女生)参与了基线调查,1973名学生(1 414名女生)完成了12个月的随访。根据NSSI行为的发生情况,将研究对象分成4组:基线时无NSSI行为史但随访时有NSSI行为的个体,被纳入NSSI行为首发组(n=75);基线时有NSSI行为在随访时表示最近的NSSI行为已发生在12个月以前的个体,被纳入NSSI行为终止组(n=81);基线和随访时都存在NSSI行为的个体,被纳入NSSI行为持续组
Non-suicidal self-injury (NSSI) mainly begins in adolescence and is associated with poor mental health. Tatnell, a researcher from Australia, conducted a 12-month cohort study to explore the role of individual factors (cognitive re-rating, self-efficacy, self-esteem) and interpersonal factors (attachment, social support) in NSSI behavior. The study involved 2 637 students (1 793 girls) from 40 secondary schools in Australia in a baseline survey and 1973 students (1 414 girls) completed a 12-month follow-up. According to the occurrence of NSSI, the subjects were divided into 4 groups: those with no history of NSSI at baseline but those with NSSI at follow-up were included in the NSSI group (n = 75); NSSI at baseline was followed up at follow-up The most recent NSSI behaviors occurred in individuals 12 months ago and were included in the NSSI termination group (n = 81). Individuals with NSSI at baseline and at follow-up were included in the NSSI Behavioral Continuation Group
