At a child psychiatry clinic 122 boys were scored on scales of aggressiveness, noncompliance and antisocial behaviour. Their biological fathers were scored on aggressiveness and antisocial behaviour. The fathers' scores were modestly but significantly correlated with those of their sons. The correlations were also computed separately for the 64 boys whose biological fathers were no longer in the home and for the 58 whose fathers had stayed. Father-son resemblances for the latter group were considerably higher than those observed in the whole sample, and for the father-absent group were insignificant.
A randomized controlled trial of several strategies designed to reduce the use of laboratory tests by house staff was performed in two parts. Part 1 compared cost education, cost audits, and both methods combined, all after a baseline observation period. Significant reductions were achieved only in the combination group for the categories of total tests (9.4%) and Sequential Multiple Analysis (SMA)-12 (10.8%), but not for charges, SMA-6, or complete blood cell counts (CBCs). Part 2 compared a group subjected to faculty chart review with a control group. Significant reductions in total charges (9.8%), total tests (15.1%), SMA-12s (20.6%), SMA-6s (12.5%), and CBCs (18.5%) were observed in the intervention group, as compared with the control group. Among the methods examined, faculty chart review seems to be the most effective method of reducing the amount of laboratory testing performed by house staff.

Aggressive conduct disorder, defined broadly on the basis of fighting, disobedience, destructiveness, and meanness, was diagnosed in 65 out of 136 boys and 17 of 43 girls consecutively admitted to a psychiatric clinic. Psychotic, brain damaged, and seriously retarded children were excluded from the series. Boys and girls with conduct disorder differed significantly from those with other diagnoses on a number of noncriterion symptoms, particularly those grouped as reactive and egocentric. Boys with conduct disorder were more often involved in antisocial behavior, girls in precocious sexual behavior. The study presents a more detailed clinical picture of the disorder, and suggests that the presence of specific antisocial behavior may be a useful criterion for dividing affected boys into two roughly equal subgroups.
