Validation of the StimQ2: A parent-report measure of cognitive stimulation in the home.

Considerable evidence demonstrates the importance of the cognitive home environment in supporting children's language, cognition, and school readiness more broadly. This is particularly important for children from low-income backgrounds, as cognitive stimulation is a key area of resilience that mediates the impact of poverty on child development. Researchers and clinicians have therefore highlighted the need to quantify cognitive stimulation; however existing methodological approaches frequently utilize home visits and/or labor-intensive observations and coding. Here, we examined the reliability and validity of the StimQ2, a parent-report measure of the cognitive home environment that can be delivered efficiently and at low cost. StimQ2 improves upon earlier versions of the instrument by removing outdated items, assessing additional domains of cognitive stimulation and providing new scoring systems. Findings suggest that the StimQ2 is a reliable and valid measure of the cognitive home environment for children from infancy through the preschool period.

Improving Parent-Child Interactions in Pediatric Health Care: A Two-Site Randomized Controlled Trial.

BACKGROUND AND OBJECTIVES: Heterogeneity in risk among low-income families suggests the need for tiered interventions to prevent disparities in school readiness. Smart Beginnings (SB) integrates two interventions: Video Interaction Project (VIP) (birth to 3 years), delivered universally to low-income families in pediatric primary care, and Family Check-Up (6 months to 3 years), targeted home visiting for families with additional family risks. Our objective was to assess initial SB impacts on parent-child activities and interactions at 6 months, reflecting early VIP exposure. METHODS: Two-site randomized controlled trial in New York City (84% Latinx) and Pittsburgh (81% Black), with postpartum enrollment and random assignment to treatment (SB) or control. At 6 months, we assessed parent-child interactions through surveys (StimQ, Parenting Your Baby) and observation (video-recorded play, coded by using Parent-Child Interaction Rating Scales - Infant Adaptation). RESULTS: A total of 403 families were enrolled at child's birth (201 treatment) with 362 (89.8%) assessed at 6 months. Treatment families had increased StimQ, including total score (Cohen's d = 0.28; P < .001) and domains reflecting reading (d = 0.23; P = .02) and teaching (d = 0.25; P = .01), and Parent-Child Interaction Rating Scales - Infant Adaptation, including a cognitive stimulation factor (d = 0.40; P < .001) and domains reflecting support for cognitive development (d = 0.36; P < .001), and language quantity (0.40; P < .001) and quality (d = 0.37; P < .001). Thus, significant effects emerged across a broad sample by using varied methodologies. CONCLUSIONS: Findings replicate and extend previous VIP findings across samples and assessment methodologies. Examining subsequent assessments will determine impacts and feasibility of the full SB model, including potential additive impacts of Family Check-Up for families at elevated risk.

Father involvement in infancy predicts behavior and response to chronic stress in middle childhood in a low-income Latinx sample.

Fathers' involvement in early childhood is important for children's physical, emotional, and cognitive development, particularly in low-income families. However, little is known about the longitudinal relations between early father involvement and children's later physiological responses to chronic stress and behaviors impacted by stress in the context of poverty. These issues are particularly important among Latinx immigrant families who face significant psychosocial and poverty-related risk. In the current study, we examined the relationship between father involvement in infancy and physiological chronic stress in the middle childhood period, as measured through hair cortisol concentration (HCC), and several behavioral measures (attention problems, working memory) in a Latinx immigrant sample with low income. Father involvement in infancy predicted children's later HCC, and working memory in second to third grade. Father involvement also moderated the effect of HCC on working memory, such that increased HCC predicted better working memory when fathers were not involved. These findings suggest that the fathers' involvement in infancy has lasting impacts on health and behavior and that associations between physiological and behavioral measures of stress may be moderated by differences in early father involvement.

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.
