Infant-directed language following a brief behavioral parenting intervention: The importance of language quality

Date of this Version


Document Type



Behavioral parenting interventions decrease early childhood behavior problems and increase positive parenting skills. However, few studies have examined the impact of low intensity interventions for infants at risk for behavior problems on changes in parent language. This study examined the effect of a brief parenting intervention, the Infant Behavior Program, on changes in parent linguistic input and its influence on infant language. Participants were 58 mothers and their12- to 15-month-olds, with elevated levels of behavioral problems. Mothers and their infants were from primarily Hispanic and low-income backgrounds. Mother-infant dyads were randomly assigned to receive the Infant Behavior Program or standard pediatric primary care. Mothers receiving the Infant Behavior Program provided more linguistic input, which indirectly influenced infant language, and suggest targeting infants at risk for behavior problems can have a broader impact on language development.
