Reciprocity in Undesirable Parent-Child Behavior? Verbal Aggression, Corporal Punishment, and Girls' Oppositional Defiant Symptoms.

Parental verbal aggression and corporal punishment are associated with children's conduct problems and oppositional defiant disorder (ODD). The strength of bidirectional relationships among specific disruptive behaviors has been inconsistent across gender, and the direction of influence between parental aggression and girls' ODD symptoms is particularly understudied. This study tested reciprocal effects between aggressive parent behaviors and girls' ODD dimensions of oppositionality, antagonism, and irritability. Data from the Pittsburgh Girls Study (N = 2,450) were used, including annual child and parent-reported aggressive discipline and girls' parent-reported ODD symptoms between ages 5 and 16. Separate clustered Poisson regression models examined change in parent or child behavior outcomes using predictors lagged by one time point. After controlling for demographic factors, behavior stability, and other disruptive behaviors, parent-reported corporal punishment predicted girls' increasing antagonism and irritability, whereas child-reported corporal punishment was unrelated to ODD symptom change. Both parent- and child-reported verbal aggression predicted increases across ODD dimensions. Girls' oppositionality and antagonism predicted increasing parent-reported verbal aggression over time, but only oppositionality was significantly related to child-reported verbal aggression. Although ODD symptoms were unrelated to change in corporal punishment, attention deficit/hyperactivity disorder (ADHD) predicted increasing parental aggression of both types. Bidirectional associations emerged such that parental verbal aggression escalates reciprocally with girls' behavioral ODD symptoms. Verbal aggression contributed to increasing irritability, but irritability did not influence parenting behavior. "Child effects" may be most salient for behavioral ODD symptoms in transaction with verbal aggression and for ADHD symptoms in predicting worsening corporal punishment and verbal aggression.
