青少年自伤的分类:基于潜在剖面分析

The Classification of Self-injury in Adolescents:Based on Latent Profile Analysis

采用青少年自我伤害问卷对2388名过去一年里有过自伤史的青少年进行施测,并采用潜在剖面分析方法探讨青少年自伤的分类模式,以及人口学变量对青少年Ⅱ类自伤异质性的作用。结果发现,青少年自伤存在明显的异质性,首先,根据性质不同,将青少年的自伤行为分为Ⅰ类自伤和Ⅱ类自伤;其次,根据自我伤害程度,进一步将Ⅱ类自伤分为轻度自伤、较轻度自伤、中度自伤、较重度自伤和重度自伤;性别和家庭所在地主要对青少年Ⅱ类自伤中的轻度/较轻度自伤产生影响,年龄对青少年Ⅱ类自伤的5种潜在类别均有影响。

In this study,2388 adolescents with a history of self-injury in the past year were tested with the Adolescents Self-Harm Scale and the method of latent class analysis(LCA)was used to explore the classification model of adolescent self-injury and to explore the effect of demographic variables on the heterogeneity of type Ⅱ NSSI in adolescents.The study indicated that there was obvious heterogeneity in adolescent self-injury.Firstly,according to the different nature,it is divided into two types:Type Ⅰ NSSI and type Ⅱ NSSI,and secondly,according to the level of self-injury,type Ⅱ NSSI was further divided into mild self-injury,slightly mild self-injury,moderate self-injury,severe self-injury and more severe self-injury.Sex and family location mainly affect mild/slightly mild self-injury in adolescent type Ⅱ NSSI,while age impacts all the five potential types of adolescent type Ⅱ NSSI.
