Co-occurrence of aggressive behavior and rule-breaking behavior at age 12: Multi-rater analyses

Aggressive Behavior (AGG) and Rule-Breaking Behavior (RB) are two of the eight CBCL syndromes. The phenotypic correlation between AGG and RB ranges from .48 to .76, and varies depending on the rater and the sex of the child. Prevalence of AGG and RB (i.e., T ≥ 67) is in the range of 6%-7% in both boys and girls. Fifty percent to 60% of the children who are deviant on AGG are also deviant on RB and vice versa. Why so many children show problem behavior in the clinical range for both syndromes is unclear. This co- occurrence could be due to genetic factors influencing both traits, to environment... Mehr ...
