Non-suicidal self-injury (NSSI) co-occurs with both other maladaptive behaviors (e.g., aggression) and emotion dysregulation. However, the extent to which these maladaptive behaviors are linked to NSSI independent of emotion dysregulation is unclear. The present study examined relationships between NSSI and six other maladaptive behaviors among university undergraduates. When controlling for demographic variables, emotion dysregulation, and other maladaptive behaviors, binge eating, purging, illicit drug use, and physical aggression were each related to lifetime NSSI history and/or severity. No maladaptive behaviors were significantly related to the presence of current diagnostic-level NSSI in these multivariate analyses. Results suggest that some maladaptive behaviors may relate uniquely to NSSI risk independent of emotion dysregulation, highlighting the importance of considering such behaviors in self-injury assessment and treatment.
非自杀性自伤 (NSSI) 与其他适应不良行为（如攻击性）和情绪失调同时发生。然而，这些适应不良行为与 NSSI 在不受情绪失调影响的情况下的关联程度尚不清楚。本研究调查了大学生中 NSSI 与其他六种适应不良行为之间的关系。在控制人口统计学变量、情绪失调和其他适应不良行为后，暴食、催吐、非法药物使用和身体攻击均与 NSSI 的终生史和/或严重程度相关。在这些多变量分析中，没有任何适应不良行为与当前诊断水平的 NSSI 的存在显著相关。研究结果表明，一些适应不良行为可能与情绪失调无关，与 NSSI 风险有独特的关联，这突出了在自我伤害评估和治疗中考虑这些行为的重要性。
