This 3-wave study investigated the developmental trajectories of nonsuicidal self-injury (NSSI) and intrapersonal/interpersonal risk factors among 3,381 Chinese adolescents (56.2% females) aged from 13 to 17 years during a 1-year period. Using an accelerated longitudinal design and latent class growth analysis, we identified four subgroups of NSSI trajectories: negligible (74.6%), experimental (12.8%), moderate decreasing (10.8%), and high fluctuating (1.9%). Adolescents reporting both intrapersonal (i.e., impulsive behaviors and depression) and interpersonal (i.e., unstable relationships and parental criticism) risk factors were significantly more likely to follow the latter three trajectories. The findings of this study suggest there is heterogeneity in NSSI development among adolescents and highlight the contributions of both intrapersonal and interpersonal risk factors in the engagement in NSSI.
这项三波研究调查了 3381 名年龄在 13 至 17 岁的中国青少年（56.2%为女性）在一年内非自杀性自我伤害（NSSI）和人际/内在风险因素的发展轨迹。使用加速纵向设计和潜在类别增长分析，我们确定了 NSSI 轨迹的四个亚组：可忽略（74.6%）、实验性（12.8%）、中度减少（10.8%）和高波动（1.9%）。报告既有内在（即冲动行为和抑郁）又有人际（即不稳定的关系和父母批评）风险因素的青少年更有可能遵循后三个轨迹。这项研究的结果表明，青少年的 NSSI 发展存在异质性，并强调了内在和人际风险因素在参与 NSSI 中的作用。
