关于青少年自我伤害的纵向数据很少。随着时间的推移，人们对各种形式的自残思想和行为之间的联系知之甚少，特别是在与预防工作最相关的社区样本中。这项研究考察了NSSI作为青少年自杀念头、威胁或手势以及在两年半的时间间隔内企图自杀的时间不变的前瞻性预测因子。一个不同的(55%女性；51%非白人)青少年社区样本(n=399)报告了抑郁症状、NSSI频率、自杀意念、威胁或手势，以及在九年级(即基线)和随后四个时间点的尝试。通过广义估计方程和Logistic回归揭示基线NSSI与基线后每个自杀自残结果的可能性之间的关联，同时控制抑郁症状和自杀自残的相关指数作为相互竞争的预测因素。基线NSSI与自杀意念和自杀企图的升高显著相关，但与威胁或手势无关。无论是性别还是种族都不会影响结果。除了抑郁症状和既往自杀等已确立的危险因素外，青少年NSSI在确定后来自杀的风险时可能是一个特别重要的评估因素。
Longitudinal data on adolescent self-injury are rare. Little is known regarding the associations between various forms of self-injurious thoughts and behaviors over time, particularly within community samples that are most relevant for prevention efforts. This study examined NSSI as a time-invariant, prospective predictor of adolescent suicide ideation, threats or gestures, and attempts over a 2.5 year interval. A diverse (55% female; 51% non-White) adolescent community sample (n = 399) reported depressive symptoms, frequency of NSSI, suicide ideation, threats or gestures, and attempts in ninth grade (i.e., baseline) and at four subsequent time points. Generalized estimating equations and logistic regressions were conducted to reveal the associations between baseline NSSI and the likelihood of each suicidal self-injury outcome post-baseline while controlling for depressive symptoms and related indices of suicidal self-injury as competing predictors. Baseline NSSI was significantly, prospectively associated with elevated levels of suicide ideation and suicide attempts, but not threats or gestures. Neither gender nor ethnicity moderated results. Above and beyond established risk factors such as depressive symptoms and previous suicidality, adolescent NSSI may be an especially important factor to assess when determining risk for later suicidality.
