Sexual and gender minority (SGM) populations are at increased risk for several negative psychological outcomes, including self-injury. Although correlates of self-injurious thoughts and behaviors (SITBs) have been identified, it is unclear which factors are prospective predictors of SITB engagement in SGM youth. The current study investigated an online sample of 252 SGM adolescents over a 6-month period. Participants reported attitudes based on SGM identity, depression, self-criticism, body image, family support and family strain, friend NSSI engagement, and experiences of everyday discrimination. Lasso and elastic net regularized logistic regressions were used to examine which baseline variables were associated with SITB engagement at follow-up. Models resulted in excellent predictive accuracy of nonsuicidal self-injury and suicidal ideation (mean Area Under the Receiving Operating Characteristics Curve [AUC] of 0.90 and 0.91), good predictive accuracy for suicide plans (mean AUC = 0.85), and fair predictive accuracy for suicidal behaviors (mean AUC = 0.78). Several variables emerged as prospectively related to SITB risk, with varied associations across different SITBs. Results suggest that minority-specific factors may predict SITBs in SGM adolescents.

性少数群体（SGM）人群面临着多种负面心理后果的风险，包括自我伤害。尽管已经确定了自我伤害想法和行为（SITBs）的相关因素，但尚不清楚哪些因素是 SGM 青少年 SITB 参与的前瞻性预测因素。本研究在 6 个月的时间内对 252 名 SGM 青少年进行了在线样本调查。参与者根据 SGM 身份、抑郁、自我批评、身体形象、家庭支持和家庭紧张、朋友的 NSSI 参与以及日常歧视经历报告了态度。使用套索和弹性网络正则化逻辑回归来检查哪些基线变量与随访时的 SITB 参与相关。模型对非自杀性自我伤害和自杀意念的预测准确率非常高（平均接受者操作特征曲线下面积 [AUC] 为 0.90 和 0.91），对自杀计划的预测准确率较高（平均 AUC = 0.85），对自杀行为的预测准确率中等（平均 AUC = 0.78）。有几个变量被确定为与 SITB 风险有前瞻性关联，在不同的 SITB 中有不同的关联。研究结果表明，特定于少数群体的因素可能会预测 SGM 青少年的 SITB。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
