青少年和年轻人中非自杀性自伤（自伤，14%-17%）的高发生率表明，一些自伤者可能比其他人表现出更多或不同的精神问题。在本研究中，作者利用潜在分类分析来识别临床不同的自伤者亚群。参与者是205名有自伤史或更多自伤行为的年轻人。根据方法（例如，割伤、咬伤、烧伤）、描述性特征（例如，单独或与他人一起自残）和功能（例如，社交与自动）确定潜在类别。分析得出了自残者的4个亚组，然后比较了他们的抑郁、焦虑、边缘型人格障碍和自杀倾向。几乎80%的参与者属于2个潜在类别中的1个，其特征是较少或较轻的自伤行为和较少的临床症状。第三类（11%的参与者）表现出各种自伤行为，支持社会和自动功能，并以高度焦虑为特征。第四类（11%的参与者）在私下里自残，为自动功能服务，其特点是高自杀率。讨论了临床和研究意义。
High rates of nonsuicidal self-injury (NSSI; 14%-17%) in adolescents and young adults suggest that some self-injurers may exhibit more or different psychiatric problems than others. In the present study, the authors utilized a latent class analysis to identify clinically distinct subgroups of self-injurers. Participants were 205 young adults with a history of I or more NSSI behaviors. Latent classes were identified on the basis of method (e.g., cutting vs. biting vs. burning), descriptive features (e.g., self-injuring alone or with others), and functions (i.e., social vs. automatic). The analysis yielded 4 subgroups of self-injurers, which were then compared on measures of depression, anxiety, borderline personality disorder, and suicidality. Almost 80% of participants belonged to I of 2 latent classes characterized by fewer or less severe NSSI behaviors and fewer clinical symptoms. A 3rd class (11% of participants) performed a variety of NSSI behaviors, endorsed both social and automatic functions, and was characterized by high anxiety. A 4th class (11% of participants) cut themselves in private, in the service of automatic functions, and was characterized by high suicidality. Clinical and research implications are discussed.
