This study examined the relation of inept parental discipline, poor parental monitoring, and children's coercive behavior to children's antisocial behavior. Subjects were 78 girls and 94 boys of kindergarten age and their two-parent families. Parental discipline and child behavior were measured by means of laboratory and phone interviews of parents. Results indicated that the strongest predictor of children's antisocial behavior was inept parental discipline. There were no differences between children on the basis of gender. Mothers reacted more negatively to daughters than did fathers; fathers reacted more negatively to sons than did mothers. The only other difference noted between mothers and fathers was that mothers spent more time with their children. Six references are cited. (BC)
