Nonsuicidal self-injury (NSSI) typically begins in adolescence and remits by early adulthood, but few prospective studies have investigated the long-term impact of NSSI initiation and cessation on young people's wellbeing. We examined changes in psychosocial risk associated with NSSI onset and offset in an accelerated longitudinal study of 662 adolescents (12-18 years old) who were followed biennially for 10 years. Of the 133 participants who reported NSSI, 100 had stopped engaging in NSSI by the study's end. NSSI initiation was associated with concurrent increases in depression, anxiety, externalizing symptoms, peer victimization, alcohol, tobacco and illicit substance use, and concurrent declines in physical self-concept, parent, and peer support. As NSSI persisted, youth experienced further increases in anxiety and cannabis use, and declines in physical self-concept. NSSI cessation was associated with concurrent increases in alcohol, cannabis, and tobacco use. With sustained cessation, however, youth experienced gradual improvements in depression, anxiety, externalizing symptoms, peer victimization, as well as gradual reductions in alcohol and tobacco use. By early adulthood, participants who reported ongoing NSSI worked fewer hours and were more likely to delay medical treatment for financial reasons versus those without NSSI histories, and reported less environmental mastery versus those who had discontinued NSSI. Youth who had discontinued NSSI, in turn, reported less environmental mastery and self-acceptance versus youth who never engaged in NSSI. These results contextualize NSSI cessation alongside indicators of psychological, social, and behavioral wellbeing, and underscore the persistence of psychosocial vulnerability after NSSI has resolved.

停止自残，然后呢？从青春期到成年早期与开始和停止非自杀性自我伤害相关的社会心理风险。

非自杀性自伤 (NSSI) 通常始于青春期并在成年早期缓解，但很少有前瞻性研究调查 NSSI 开始和停止对年轻人健康的长期影响。我们在一项针对 662 名青少年（12-18 岁）的加速纵向研究中检查了与 NSSI 发作和抵消相关的心理社会风险的变化，这些青少年每两年随访 10 年。在报告 NSSI 的 133 名参与者中，有 100 名在研究结束时已停止参与 NSSI。NSSI 开始与抑郁、焦虑、外化症状、同伴受害、酒精、烟草和非法物质使用的同时增加有关，以及身体自我概念、父母和同伴支持的同时下降。随着 NSSI 持续存在，青少年的焦虑和大麻使用进一步增加，和身体自我概念的下降。NSSI 停止与酒精、大麻和烟草使用的同时增加有关。然而，随着持续戒烟，青少年的抑郁、焦虑、外化症状、同伴受害逐渐改善，酒精和烟草使用逐渐减少。到成年早期，与没有 NSSI 病史的参与者相比，报告持续 NSSI 的参与者工作时间更少，并且更有可能因经济原因延迟治疗，并且与停止 NSSI 的参与者相比，他们报告的环境掌握程度较低。反过来，与从未参与过 NSSI 的青年相比，停止 NSSI 的青年报告的环境掌握和自我接受程度较低。这些结果将 NSSI 停止与心理、社会和行为健康指标结合起来，并强调 NSSI 解决后社会心理脆弱性的持续存在。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
