Objective: To determine whether positive parenting practices are associated with less aggressive and delinquent behavior in early-maturing girls.
Design: Cross-sectional survey.
Setting: Interviews with a community sample of children and their caregivers were conducted in their homes or in a research setting.
Participants: An ethnically diverse cohort of 330 fifth-grade girls (mean age, 11.25 years) from 3 metropolitan areas.
Main exposure: Early onset of menarche, parental nurturance, knowledge of the child's activities, and communication.
Main outcome measures: Physical, relational, and nonphysical aggression and delinquent behavior.
Results: A total of 25% of girls could be reliably classified as early maturers. Early maturation was associated with delinquency (b = 0.53) but not aggression. Low levels of maternal nurturance were associated with delinquency and relational aggression (both b = -0.04). Early maturation was associated with higher relational aggression only at low levels of nurturance (b = 0.94), communication (b = 1.36), and knowledge (b = 1.06) (P < .05 for each interaction). Also, early maturation only predicted physical aggression when combined with low maternal nurturance (b = 0.93).
Conclusions: Early puberty is a risk factor for delinquency, and early puberty combined with low parental nurturance, communication, or parental knowledge of the child's activities presents a risk for aggressive behavior in early adolescent girls. Early-maturing girls may benefit from increased parental nurturance, communication, and knowledge.
