Behavior Problems in Early Adolescence

for 518 seventh- and eighth-grade children by their teachers. Factor analysis revealed that the majority of the variance could be accounted for by two factors, conduct problem and problem. For the eighth grade an additional factor, apparently related to behavioral immaturity, was found. Factor scores generally were satisfactorily independent, but two-rater reliability for a subsample was disappointingly low for the personality and immaturity factors. Results were consonant with other studies using similar methods but different samples.
