The authors examined the relations between self-report measures of parental support, communication, and psychological control and measures of antisocial and delinquent behavior in a sample of 641 Spanish adolescents (M age = 14.35 years, SD = 1.53 years). Findings revealed similarities in the relations between parenting processes and both measures of deviant behavior. The results also demonstrated the need for researchers to consider the parenting effects of mothers and fathers independently. Specifically, maternal support was a negative predictor of antisocial and delinquent behaviors of male adolescents, and maternal psychological control was a positive predictor of antisocial and delinquent behaviors of female adolescents. Paternal parenting efforts did not account for additional variability.
