Links between Shared Reading and Play, Parent Psychosocial Functioning, and Child Behavior: Evidence from a Randomized Controlled Trial.

OBJECTIVE: To investigate pathways by which interventions that promote shared reading and play help prevent child behavior problems. We examined whether family processes associated with the family investment pathway (eg, parental cognitive stimulation) and the family stress pathway (eg, mothers' psychosocial functioning) mediated impacts of a pediatric-based preventive intervention on child behavior. STUDY DESIGN: The sample included 362 low-income mothers and their children who participated in a randomized controlled trial of the Video Interaction Project, a pediatrics-based preventive intervention that promotes parent-child interactions in the context of shared reading and play. Parent-child dyads were randomly assigned to group at birth. Three mediators-parental cognitive stimulation, maternal stress about the parent-child relationship, and maternal depressive symptoms-were assessed at child ages 6 and 36 months. The outcome, child externalizing behaviors, was assessed at 36 months. We used a series of path analytic models to examine how these family processes, separately or together, mediated the impacts of the Video Interaction Project on child behavioral outcomes. RESULTS: Intervention impacts on child behavior were mediated by enhancements in cognitive stimulation and by improvements in mothers' psychosocial functioning. A sequential mediation model showed that Video Interaction Project impacts on cognitive stimulation at 6 months were associated with later decreases in mothers' stress about the parent-child relationship and that this pathway mediated intervention impacts on child behavioral outcomes at 3 years of age (P = .023). CONCLUSIONS: Using an experimental design, this study identifies pathways by which parent-child interactions in shared reading and play can improve child behavioral outcomes.

Enhancing Parent Talk, Reading, and Play in Primary Care: Sustained Impacts of the Video Interaction Project.

OBJECTIVE: To determine the early impacts of pediatric primary care parenting interventions on parent cognitive stimulation in low socioeconomic status families and whether these impacts are sustained up to 1.5 years after program completion. STUDY DESIGN: This randomized controlled trial included assignment to 1 of 2 interventions (Video Interaction Project [VIP] or Building Blocks) or to a control group. Mother-newborn dyads were enrolled postpartum in an urban public hospital. In VIP, dyads met with an interventionist on days of well-child visits; the interventionist facilitated interactions in play and shared reading through provision of learning materials and review of videotaped parent-child interactions. In Building Blocks, parents were mailed parenting pamphlets and learning materials. We compare the trajectories of cognitive stimulation for parents in VIP and control from 6 to 54 months. RESULTS: There were 546 families that contributed data. VIP was associated with enhanced reading, parent verbal responsivity, and overall stimulation at all assessment points, with analyses demonstrating a 0.38 standard deviation increase in cognitive stimulation overall. Trajectory models indicated long-term persistence of VIP impacts on reading, teaching, and verbal responsivity. CONCLUSIONS: VIP is associated with sustained enhancements in cognitive stimulation in the home 1.5 years after completion of the program and support expansion of pediatric interventions to enhance developmental trajectories of children of low socioeconomic status.
