Adolescent suicidal ideation (SI) and non-suicidal self-injury (NSSI) are crucial public health issues, yet their co-developmental trajectories during early adolescence and their associations with predictors and outcomes are unclear. This study aimed to (a) identify heterogeneous co-developmental trajectories of SI and NSSI, (b) explore associations between transdiagnostic predictors and trajectories, and (c) assess suicide attempt risk across trajectories.
Four hundred fifty-three adolescents (M = 12.35 years, 48.3% boys) completed surveys at 6-month intervals across 2 years. At Time 1 (Nov 2020), participants completed surveys encompassing SI, and NSSI, along with family, peer, and individual predictors. Subsequent surveys (Times 2-4) measured SI and NSSI, with suicide attempts queried at Time 4.
Parallel process latent class growth models revealed three co-developmental groups (i.e., Stable low NSSI and SI; Moderate-NSSI and high-SI, parallel decreasing; High-NSSI and moderate-SI, parallel increasing). Multivariate logistic regression indicated that group membership was predicted by parental rejection, parental warmth, bullying victimization, depressive and anxiety symptoms, thwarted belongingness, and perceived burdensomeness. Adolescents in the "High-NSSI and moderate-SI, parallel increasing" group reported the highest suicide attempt frequency.
These findings underscore subgroup distinctions and transdiagnostic predictors in comprehending SI and NSSI progression, emphasizing the necessity of dynamic monitoring and tailored interventions for distinct subgroup characteristics.
青少年自杀意念（SI）和非自杀性自伤（NSSI）是重要的公共卫生问题，然而它们在青春期早期的共同发展轨迹以及与预测因素和结果的关联尚不清楚。本研究旨在：（a）识别SI和NSSI的异质共同发展轨迹；（b）探讨跨诊断预测因素与轨迹之间的关联；（c）评估各轨迹中的自杀未遂风险。
453名青少年（平均年龄12.35岁，48.3%为男孩）在两年内每隔6个月完成一次调查。在时间1（2020年11月），参与者完成了涵盖SI、NSSI以及家庭、同伴和个体预测因素的调查。后续调查（时间2至4）测量了SI和NSSI，并在时间4询问了自杀未遂情况。
并行过程潜在类别增长模型揭示了三个共同发展组（即稳定的低NSSI和SI组；中等NSSI和高SI组，并行下降；高NSSI和中等SI组，并行上升）。多变量逻辑回归表明，父母拒绝、父母温暖、受欺凌受害情况、抑郁和焦虑症状、归属感受挫和感知到的负担感可预测组别归属。“高NSSI和中等SI，并行上升”组的青少年报告的自杀未遂频率最高。
这些发现强调了在理解SI和NSSI进展过程中的亚组差异和跨诊断预测因素，强调了针对不同亚组特征进行动态监测和量身定制干预措施的必要性。
