Abstract
The adjustment of 16 boys treated in hospital for acting out behaviour disorders was studied. The discharge Factor I score was 157 or more in Group I (8 subjects) and 156 or below in Group II (8 subjects). As predicted, Group I boys showed significantly fewer antisocial difficulties following discharge. A low Factor I score also predicted hyperkinetic symptoms but at a much lower level of confidence and Factor III (destructive behaviour) predicted antisocial difficulties but less effectively than Factor I (disturbed behaviour towards adults). No advantage was gained by using other than the Factor I rating and it is concluded that this score based on only 10 categories helps to identify boys who on discharge will have continuing serious antisocial difficulties.
