Infant communication and subsequent language development in children from low-income families: the role of early cognitive stimulation.

Objectives: To explore the relationship between early cognitive stimulation in the home, 6-month infant communication, and 24-month toddler language in a low-socioeconomic status sample. Methods: Longitudinal analyses of mother–child dyads participating in larger study of early child development were performed. Dyads enrolled postpartum in an urban public hospital. Cognitive stimulation in the home at 6 months was assessed using StimQ-lnfant, including provision of toys, shared reading, teaching, and verbal responsivity. Early infant communication was assessed at 6 months including the following: (1) Emotion and eye gaze (Communication and Symbolic Behavior Scale DP—CSBS DP), (2) Communicative bids (CSBS DP), and (3) Expression of emotion (Short Temperament Scale for Infants). Toddler language was assessed at 24 months using the Preschool Language Scale-4, including the following: (1) expressive language and (2) auditory comprehension. Results: Three hundred twenty families were assessed. In structural equation models, cognitive stimulation in the home was strongly associated with early infant communication (&bgr; = 0.63, p <.0001) and was predictive of 24-month language (&bgr; = 0.20, p <.05). The effect of early cognitive stimulation on 24-month language was mediated through early impacts on infant communication (Indirect &bgr; = 0.28, p =.001). Reading, teaching, availability of learning materials, and other reciprocal verbal interactions were all related directly to infant communication and indirectly to language outcomes. Conclusions: The impact of early cognitive stimulation on toddler language is manifested through early associations with infant communication. Pediatric primary care providers should promote cognitive stimulation beginning in early infancy and support the expansion and dissemination of intervention programs such as Reach Out and Read and the Video Interaction Project.

Promotion of Positive Parenting and Prevention of Socioemotional Disparities.

OBJECTIVE: The goal of this study was to determine what effects pediatric primary care interventions, focused on promotion of positive parenting through reading aloud and play, have on the socioemotional development of toddlers from low-income, primarily immigrant households. METHODS: This randomized controlled trial included random assignment to 1 of 2 interventions (Video Interaction Project [VIP] or Building Blocks [BB]) 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 BB, parents were mailed parenting pamphlets and learning materials. This article analyzes socioemotional outcomes from 14 to 36 months for children in VIP and BB versus control. RESULTS: A total of 463 dyads (69%) contributed data. Children in VIP scored higher than control on imitation/play and attention, and lower on separation distress, hyperactivity, and externalizing problems, with effect sizes ∼0.25 SD for the sample as a whole and ∼0.50 SD for families with additional psychosocial risks . Children in BB made greater gains in imitation/play compared with control. CONCLUSIONS: These findings support the efficacy of VIP, a preventive intervention targeting parent–child interactions, for enhancing socioemotional outcomes in low-income toddlers. Given the low cost and potential for scalability of primary care interventions, findings support expansion of pediatric-based parenting programs such as VIP for the primary prevention of socioemotional problems before school entry.

Mitigating the Effects of Family Poverty on Early Child Development through Parenting Interventions in Primary Care

Poverty related disparities in early child development and school readiness are a major public health crisis, the prevention of which has emerged in recent years as a national priority. Interventions targeting parenting and the quality of the early home language environment are at the forefront of efforts to address these disparities. In this article we discuss the innovative use of the pediatric primary care platform as part of a comprehensive public health strategy to prevent adverse child development outcomes through the promotion of parenting. Models of interventions in the pediatric primary care setting are discussed with evidence of effectiveness reviewed. Taken together, a review of this significant body of work shows the tremendous potential to deliver evidence-based preventive interventions to families at risk for poverty related disparities in child development and school readiness at the time of pediatric primary care visits. We also addresss considerations related to scaling and maximizing the effect of pediatric primary care parenting interventions and provide key policy recommendations.

Reducing Maternal Depressive Symptoms through Promotion of Parenting in Pediatric Primary Care

We studied associations between 2 pediatric primary care interventions promoting parental responsiveness and maternal depressive symptoms among low-income mothers. This randomized controlled trial included 2 interventions (Video Interaction Project [VIP], Building Blocks [BB]) and a control group. VIP is a relationship-based intervention, using video-recordings of mother–child dyads to reinforce interactional strengths. BB communicates with parents via parenting newsletters, learning materials, and questionnaires. At mean (SD) child age 6.9 (1.2) months, depressive symptoms were assessed with the Patient Health Questionnaire-9 (PHQ-9), parental responsiveness was assessed with StimQ-I. A total of 407 dyads were assessed. Rates of mild depressive symptoms were lower for VIP (20.6%) and BB (21.1%) than Controls (32.1%, P = .04). Moderate depressive symptoms were lower for VIP (4.0%) compared to Controls (9.7%, P = .031). Mean PHQ-9 scores differed across 3 groups (F = 3.8, P = .02): VIP mothers scored lower than controls (P = .02 by Tukey HSD). Parent–child interactions partially mediated VIP-associated reductions in depressive symptoms (indirect effect −.17, 95% confidence interval −.36, −.03).

Reading Aloud, Play, and Social-Emotional Development

In an RCT of the VIP, it was demonstrated that pediatric promotion of reading aloud and play resulted in reduced hyperactivity at school entry. OBJECTIVES: To determine impacts on social-emotional development at school entry of a pediatric primary care intervention (Video Interaction Project [VIP]) promoting positive parenting through reading aloud and play, delivered in 2 phases: infant through toddler (VIP birth to 3 years [VIP 0–3]) and preschool-age (VIP 3 to 5 years [VIP 3–5]). METHODS: Factorial randomized controlled trial with postpartum enrollment and random assignment to VIP 0-3, control 0 to 3 years, and a third group without school entry follow-up (Building Blocks) and 3-year second random assignment of VIP 0-3 and control 0 to 3 years to VIP 3-5 or control 3 to 5 years. In the VIP, a bilingual facilitator video recorded the parent and child reading and/or playing using provided learning materials and reviewed videos to reinforce positive interactions. Social-emotional development at 4.5 years was assessed by parent-report Behavior Assessment System for Children, Second Edition (Social Skills, Attention Problems, Hyperactivity, Aggression, Externalizing Problems). RESULTS: VIP 0-3 and VIP 3-5 were independently associated with improved 4.5-year Behavior Assessment System for Children, Second Edition T-scores, with effect sizes (Cohen’s d) ∼−0.25 to −0.30. Receipt of combined VIP 0-3 and VIP 3-5 was associated with d = −0.63 reduction in Hyperactivity (P = .001). VIP 0-3 resulted in reduced “Clinically Significant” Hyperactivity (relative risk reduction for overall sample: 69.2%; P = .03; relative risk reduction for increased psychosocial risk: 100%; P = .006). Multilevel models revealed significant VIP 0-3 linear effects and age × VIP 3-5 interactions. CONCLUSIONS: Phase VIP 0-3 resulted in sustained impacts on behavior problems 1.5 years after program completion. VIP 3-5 had additional, independent impacts. With our findings, we support the use of pediatric primary care to promote reading aloud and play from birth to 5 years, and the potential for such programs to enhance social-emotional development.

Characteristics Associated With Adding Cereal Into the Bottle Among Immigrant Mother–Infant Dyads of Low Socioeconomic Status and Hispanic Ethnicity

Objective: Determine maternal and infant characteristics associated with adding cereal into the bottle. Design: Secondary data analysis. Participants: Study participants were immigrant, low‐income, urban mother–infant dyads (n = 216; 91% Hispanic, 19% US‐born) enrolled in a randomized controlled trial entitled the Bellevue Project for Early Language, Literacy and Education Success. Main Outcome Measures: Maternal characteristics (age, marital status, ethnicity, primary language, country of origin, education, work status, income, depressive symptoms, and concern about infants future weight) and infant characteristics (gender, first born, and difficult temperament). Analysis: Fisher exact test, chi‐square test, and simultaneous multiple logistic regression of significant (P < .05) variables identified in unadjusted analyses. Results: Twenty‐seven percent of mothers added cereal into the bottle. After adjusting for confounding variables identified in bivariate analyses, mothers who were single (P = .02), had moderate to severe depressive symptoms (P = .01) and perceived their infant had a difficult temperament (P = .03) were more likely to add cereal into the bottle. Conversely, mothers who expressed concern about their infants becoming overweight were less likely to add cereal (P = .02). Conclusions and Implications: Health care providers should screen for adding cereal in infant bottles. Further research is needed to investigate the impact of adding cereal into the bottle on weight trajectories over time. Causal associations also need to be identified to effectively prevent this practice.

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.

Reading aloud and child development: A cluster-randomized trial in Brazil

This cluster-randomized trial shows that a parenting program promoting reading aloud enhanced child language and cognitive development in a low-income community in Brazil. OBJECTIVES: Many children in low- and middle-income countries fail to reach their developmental potential. We sought to determine if a parenting program focused on the promotion of reading aloud enhanced parent-child interactions and child development among low-income families in northern Brazil. METHODS: This was a cluster-randomized study of educational child care centers randomly assigned to receive an additional parenting program (intervention) or standard child care without a parenting component (control). Parent-child dyads were enrolled at the beginning of the school year and were assessed at enrollment and at the end of the school year. Families in intervention centers could borrow children’s books on a weekly basis and could participate in monthly parent workshops focused on reading aloud. We compared parents and children in intervention and control centers 9 months after the start of the intervention on measures of parent-child interaction and child language, cognitive, and social-emotional development. RESULTS: Five hundred and sixty-six parent-child dyads (279 intervention; 287 control) in 12 child care clusters (26–76 children per cluster) were assessed at enrollment; 464 (86%) contributed follow-up data. Parents in the intervention group engaged in significantly greater cognitive stimulation (Cohen’s d = 0.43) and higher quantity and quality of reading interactions (d = 0.52–0.57) than controls; children in the intervention scored significantly higher than controls on receptive vocabulary (d = 0.33), working memory (d = 0.46), and IQ (d = 0.33). CONCLUSIONS: An innovative program focused on the promotion of parent-child reading aloud resulted in benefits to parent-child interactions and to child language and cognitive development that were greater than those provided by educational child care alone. This promising approach merits further evaluation at scale.
