“…However, when data from boys and girls are analyzed separately, there can be different conclusions for boys and girls (e.g., Coie, Terry, Lenox, et al, 1995). Moreover, when sex has been explicitly tested as a moderator (i.e., Predictor × Sex Interaction), differences in specific parenting (e.g., McFaydenKetchum, Bates, Dodge, & Pettit, 1996) and peer relationship (e.g., Kupersmidt, Burchinal, & Patterson, 1995;Laird et al, 1999) processes predicting antisocial behavior development have been identified. It is not clear, however, whether sex differences are so pervasive as to indicate the need for different models for boys and girls.…”
