Research indicates that child depression and bipolar disorder often co-occur with other psychological conditions, and the links among mood disorder, anxiety, and aggression are studied separately. However, some research explains that norepinephrine (NE) and serotonin (5HT) systems are abnormal in both depression and anxiety, and NE and 5HT dysregulation may lead to aggression (Ressler et al, 2000). Therefore, it is important to look at the singular and composite relationships among mood disorder, anxiety, and aggression simultaneously. Two hundred sixty four community subjects were recruited, and parents and their child completed a diagnostic assessment as a screening or baseline evaluation, after giving informed consent. Also, parents completed the Child Behavior Checklist (CBCL; Achenbach, 1991 a) and their child completed the Youth Self Report (YSR, Achenbach, 1991 b). Ö coefficient correlations were computed to compare the relationships among mood disorder, anxiety, and aggression. In addtion, one way ANOVA was computed to compare T scores on the aggression, delinquent behavior, and oppositional defiant disorder scales, between depression and bipolar youths for both the CBCL and YSR. The results show the relationships among anxiety, depression, and aggression have weak positive correlations in depressed and bipolar youths. Implications and suggestions for future research are also discussed.
