Abstract
The subjects of this study were 283 $6^{th}$ and $8^{th}$ grade students and their homeroom teachers. Data were analyzed by frequency, %, Pearson's, two-way ANOVA, and stepwise regression. Results showed that open communication with parents and self-esteem were positively related to social competence and negatively related to antisocial behavior. Depression was negatively related to social competence and positively related to antisocial behavior. The $8^{th}$ graders had higher scores than $6^{th}$ graders in antisocial behavior and lower levels of social competence and communication with parents. Girls were higher in social competence and communication with parents and lower in antisocial behavior than boys. Depression impacted social competence in girls, and communication with fathers impacted social competence in boys. Grade, open communication with fathers, and self-esteem had significant effects on the antisocial behavior in boys.
