Recent studies suggest a higher threshold number of self-injuries during the past year than the one proposed in the DSM-5 criteria for non-suicidal self-injury disorder (NSSID). Therefore, we aimed to test a validity of the frequency criterion in girls with conduct disorder (CD) based on psychopathology and the level of functioning. Mixture modelling analysis revealed that the frequency of at least 8 self-harm behaviours in the previous year differentiated adolescents with CD. Thus, we divided adolescents into three subgroups: group 1: at least 8 self-harm acts; group 2: 1-7 self-harm behaviours and group 3: those who did not injure themselves during the last 12 months. Individuals from group 1 were significantly younger and had earlier age of self-harm onset. There were significant differences between groups 1 and 3 in terms of anxiety and depressive symptoms, self-esteem, aggression and the global functioning level. The group 1 scored significantly higher on depressive symptoms compared to the group 2. The group 2 scored significantly higher than the group 3 on the level of hostility. Our results provide further evidence supporting the need for modification of the NSSID frequency criterion.
最近的研究表明，过去一年中自我伤害的次数高于 DSM-5 非自杀性自我伤害障碍 (NSSID) 标准中提出的次数。因此，我们旨在基于精神病理学和功能水平测试行为障碍女孩中频率标准的有效性。混合模型分析显示，过去一年中至少有 8 次自我伤害行为可以区分患有 CD 的青少年。因此，我们将青少年分为三组：第 1 组：至少有 8 次自伤行为；第 2 组：1-7 次自伤行为；第 3 组：过去 12 个月没有伤害自己的人。第 1 组的个体明显更年轻，且自伤开始的年龄更早。第 1 组和第 3 组在焦虑和抑郁症状、自尊、攻击性和整体功能水平方面存在显著差异。与第 2 组相比，第 1 组在抑郁症状方面得分明显更高。第 2 组在敌意水平上的得分明显高于第 3 组。我们的研究结果进一步支持了需要修改 NSSID 频率标准的观点。
