ABSTRACT
<p><b>OBJECTIVE</b>To study the major social-psychological factors contributing to male juvenile delinquency.</p><p><b>METHODS</b>One hundred and thirty-seven cases of male juvenile delinquents (delinquent group) and 145 aged-matched male students (control group) were enrolled in this case-control study. A questionnaire survey was conducted using the Adolescent Self-Rating Life Events Check List, the Coping Style Questionnaire, the Family Environment Scale-Chinese version, and the Social Support Rating Scale.</p><p><b>RESULTS</b>The monovariate analysis showed that the total score and the scores of some factors of negative life events, the scores of immature coping styles and family conflicts, and the proportion of broken families in the delinquent group were significantly higher than those in the control group. In contrast, the scores of educational levels, study stress factor in the negative life events, mature coping styles, family environments and social supports were significantly lower in the delinquent group than those in the control group. The multivariate factors analysis showed that 7 variables were enrolled into the discriminatory equations, including negative life events (interpersonal relationship and healthy adaptation), self-condemn styles, family conflicts, subjective supports, objective supports, and utilization of social supports. The total accuracy of this equation was 92.2%.</p><p><b>CONCLUSIONS</b>Negative life events in the interpersonal relationship and healthy adaptation, self-condemn styles, family conflicts, and weak social support system may be major social-psychological factors contributing to male juvenile delinquency.</p>
