攻击性初中生的类别:一个潜在类别模型的应用

A Latent Class Analysis of Adolescent Aggression Behaviours

旨在对攻击初中生进行分类,以攻击行为特征来划分初中生。294名初中生参加了为期一年的短期纵向追踪研究,在一年中分四次完成问卷。用潜在类别模型分析了初二到初三时攻击性青少年的类别,结果表明初中生存在三种攻击类别——高攻击型、低攻击型和混合型。研究还发现相比于低攻击型,混合型攻击初中生在初二及初三中期有显著的性别差异。

Adolescent aggression behavior has recently drawn attentions as a determinant of social and personality devel- opment. The researches adopted continuous variables can indicate the quantitative relationship or the change on the degree or the frequency of aggression. The current aggression research needs some conclusion from the perspective of categorical variable. Such study can show the pattern of aggression behavior. The latent class model can deal with the categorical variable. This study describes patterns of youth aggression profiles. 294 participants attend this longitudinal study. Aggression behaviors were assessed 4 times in a year. These participants fulfilled the self-report questionnaire measuring three forms of aggression. Through recoding the scores that participants answered, we get a set of dichotomous data which indicated the present of corresponding specific aggression behaviors or not. Latent class analysis was used to classify youth based on their aggression profiles. The results indicate that there are three aggression patterns in adolescence, high aggressive, low aggressive and mixture pattern, respectively. The high ag- gressive pattern indicated that there are common more frequent behaviors in three aggression forms. On the contra- ry, there are common less frequent behaviors in three aggression forms. The mixture pattern is a special one where there weren＇ t consistent frequency in there aggression behavior.
