This study explored the growth of non-suicidal self-injury (NSSI) frequency over 2.5 years in a clinical sample of adolescent girls. Following a functional model of NSSI, the contribution of emotion dysregulation, peer victimization, and psychological maladjustment were evaluated as the predictors of NSSI trajectories. Participants of 99 girls ( = 16.03 years) were admitted for psychiatric hospitalization, who responded to questionnaires assessing NSSI, emotion dysregulation, relational and overt peer victimization, and internalizing and externalizing symptoms. NSSI was also assessed at 6 months and 2.5 years following the baseline assessment. Linear mixed modeling estimated NSSI frequency over time. The findings highlight the stable nature of NSSI and the contribution of emotion dysregulation and internalizing symptoms to NSSI patterns. Peer victimization and externalizing behavior problems were not the significant predictors. Developing interventions targeting these NSSI predictors early in girls' development may prevent the emergence and maintenance of NSSI.
本研究探讨了在一个青春期女孩临床样本中，非自杀性自伤（NSSI）频率在2.5年期间的增长情况。遵循NSSI的功能模型，评估了情绪失调、同伴受害和心理适应不良作为NSSI轨迹预测因素的作用。99名女孩（平均年龄=16.03岁）因精神科住院参与研究，她们对评估NSSI、情绪失调、关系型和公然的同伴受害以及内化和外化症状的问卷作出回应。在基线评估后的6个月和2.5年时也对NSSI进行了评估。线性混合模型估计了随时间变化的NSSI频率。研究结果突出了NSSI的稳定性，以及情绪失调和内化症状对NSSI模式的作用。同伴受害和外化行为问题并非显著的预测因素。在女孩发育早期针对这些NSSI预测因素开展干预措施，可能会预防NSSI的出现和持续。
