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).

AIM: To establish whether young children watched foreground electronic media or background media that was not aimed at them or was inappropriate for their age. METHODS: We performed a longitudinal analysis of mother-infant dyads participating in a larger parenting study. The primary dependent variable was maternal reports of watching habits from media diaries at 6, 14, 24 and 36 months. Independent variables were child age, programme content and whether the programme was turned on specifically for the child. RESULTS: We analysed 3570 programme exposures in 527 children, mostly from television. Children were significantly more likely to actually watch programmes if they were older, if the content was coded as 'educational young child' or if the parent tuned on the programme specifically so the child could watch it. Children under the age of two were more likely than older children to watch background media that featured age-inappropriate content or had not been turned on for them to watch [30% versus 16% of programmes; AOR = 2.19 (95%CI 1.82-2.65)]. CONCLUSION: Young children under the age of two frequently watch background media that has age-inappropriate content or has not been turned on for them to watch.

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 (beta = 0.63, p <.0001) and was predictive of 24-month language (beta = 0.20, p <.05). The effect of early cognitive stimulation on 24-month language was mediated through early impacts on infant communication (Indirect beta = 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.

OBJECTIVE: To determine the effects of pediatric primary care interventions on parent-child interactions in families with low socioeconomic status. DESIGN: In this randomized controlled trial, participants were randomized to 1 of 2 interventions (Video Interaction Project [VIP] or Building Blocks [BB]) or the control group. SETTING: Urban public hospital pediatric primary care clinic. PARTICIPANTS: Mother-newborn dyads enrolled post partum from November 1, 2005, through October 31, 2008. INTERVENTIONS: In the VIP group, mothers and newborns participated in 1-on-1 sessions with a child development specialist who facilitated interactions in play and shared reading by reviewing videos made of the parent and child on primary care visit days; learning materials and parenting pamphlets were also provided. In the BB group, parenting materials, including age-specific newsletters suggesting interactive activities, learning materials, and parent-completed developmental questionnaires, were mailed to the mothers. MAIN OUTCOME MEASURES: Parent-child interactions were assessed at 6 months with the StimQ-Infant and a 24-hour shared reading recall diary. RESULTS: A total of 410 families were assessed. The VIP group had a higher increased StimQ score (mean difference, 3.6 points; 95% confidence interval, 1.5 to 5.6 points; Cohen d, 0.51; 0.22 to 0.81) and more reading activities compared to the control group. The BB group also had an increased overall StimQ score compared with the control group (Cohen d, 0.31; 95% confidence interval, 0.03 to 0.60). The greatest effects for the VIP group were found for mothers with a ninth-grade or higher reading level (Cohen d, 0.68; 95% confidence interval, 0.33 to 1.03). CONCLUSIONS: The VIP and BB groups each led to increased parent-child interactions. Pediatric primary care represents a significant opportunity for enhancing developmental trajectories in at-risk children. Trial Registration clinicaltrials.gov Identifier: NCT00212576

OBJECTIVE: To determine whether duration and content of media exposure in 6-month-old infants are associated with development at age 14 months. DESIGN: Longitudinal analysis of 259 mother-infant dyads participating in a long-term study related to early child development, from November 23, 2005, through January 14, 2008. SETTING: An urban public hospital. PARTICIPANTS: Mothers with low socioeconomic status and their infants. Main Exposure Duration and content of media exposure at age 6 months. MAIN OUTCOME MEASURES: Cognitive and language development at age 14 months. RESULTS: Of 259 infants, 249 (96.1%) were exposed to media at age 6 months, with mean (SD) total exposure of 152.7 (124.5) min/d. In unadjusted and adjusted analyses, duration of media exposure at age 6 months was associated with lower cognitive development at age 14 months (unadjusted: r = -0.17, P < .01; adjusted: beta = -0.15, P = .02) and lower language development (r = -0.16, P < .01; beta = -0.16, P < .01). Of 3 types of content assessed, only 1 (older child/adult-oriented) was associated with lower cognitive and language development at age 14 months. No significant associations were seen with exposure to young child-oriented educational or noneducational content. CONCLUSIONS: This study is the first, to our knowledge, to have longitudinally assessed associations between media exposure in infancy and subsequent developmental outcomes in children from families with low socioeconomic status in the United States. Findings provide strong evidence in support of the American Academy of Pediatrics recommendations of no media exposure prior to age 2 years, although further research is needed

OBJECTIVE:: To determine whether screening children in an urban pediatric emergency department (PED) would lead to identification of previously undiagnosed developmental delay. METHODS:: This was a cross-sectional study of families presenting to an urban public hospital PED with children 6 to 36 months and no history of developmental delay. Children were screened for possible developmental delay using the Ages and Stages Questionnaire; parents completed an instrument that assesses 5 domains: communication, gross motor, fine motor, problem solving, and personal-social. Sociodemographic data were also obtained. RESULTS:: One hundred thirty-eight children were enrolled, all accompanied by their mothers. Mean age of the children was 18.9 months; 51.5% were female; 56.8% of the mothers were high-school graduates; 59.9% were immigrants; 75.4% were Latino. Twenty-one percent did not have a regular source of primary care; 26.8% (95% confidence interval, 20.1%-34.8%) screened positive in at least 1 domain, with a trend toward the highest percentage of positive screens on the communication domain (z = 1.89, P = 0.059). In a simultaneous multiple logistic regression model including all predictor variables, child age of 12 to 30 months was associated with increased adjusted odds of positive screen (adjusted odds ratio, 8.4; 95% confidence interval, 1.4-48.9). Having a primary caregiver born in the United States was statistically significant for screening positive in at least 1 Ages and Stages Questionnaire domain (P = 0.03). CONCLUSIONS:: Almost 30% of 6- to 36-month-old children presenting to an urban PED without prior developmental concerns screened positive for possible delay, suggesting the utility of performing routine developmental screening in the PED. Pediatric emergency department use alone may be an indication for screening. Further study is needed for feasibility of screening for delay in the PED

OBJECTIVE: To determine whether maternal literacy level accounts for associations between educational level and the cognitive home environment in low-income families. DESIGN: Analysis of 369 mother-infant dyads participating in a long-term study related to early child development. SETTING: Urban public hospital. PARTICIPANTS: Low-income mothers of 6-month-old infants. MAIN EXPOSURE: Maternal literacy level was assessed using the Woodcock-Johnson III/Bateria III Woodcock-Munoz Tests of Achievement, Letter-Word Identification Test. Maternal educational level was assessed by determining the last grade that had been completed by the mother. MAIN OUTCOME MEASURE: The cognitive home environment (provision of learning materials, verbal responsivity, teaching, and shared reading) was assessed using StimQ, an office-based interview measure. RESULTS: In unadjusted analyses, a maternal literacy level of ninth grade or higher was associated with increases in scores for the overall StimQ and each of 4 subscales, whereas a maternal educational level of ninth grade or higher was associated with increases in scores for the overall StimQ and 3 of 4 subscales. In simultaneous multiple linear regression models including both literacy and educational levels, literacy continued to be associated with scores for the overall StimQ (adjusted mean difference, 3.7; 95% confidence interval, 1.7-5.7) and all subscales except teaching, whereas maternal educational level was no longer significantly associated with scores for the StimQ (1.8; 0.5-4.0) or any of its subscales. CONCLUSIONS: Literacy level may be a more specific indicator of risk than educational level in low-income families. Studies of low-income families should include direct measures of literacy. Pediatricians should develop strategies to identify mothers with low literacy levels and promote parenting behaviors to foster cognitive development in these at-risk families

OBJECTIVE: To assess verbal interactions related to television and other electronic media exposure among mothers and 6 month-old-infants. DESIGN: Cross-sectional analysis of 154 mother-infant dyads participating in a long-term study related to early child development. SETTING: Urban public hospital. PARTICIPANTS: Low socioeconomic status mothers of 6-month-old infants. Main Exposure Media exposure and content. MAIN OUTCOME MEASURES: Mother-infant verbal interaction associated with media exposure and maternal coviewing. RESULTS: Of 154 low socioeconomic status mothers, 149 (96.8%) reported daily media exposure in their infants, with median exposure of 120 (interquartile range, 60-210) minutes in a 24-hour period. Among 426 program exposures, mother-infant interactions were reported during 101 (23.7%). Interactions were reported most frequently with educational young child-oriented media (42.8% of programs), compared with 21.3% of noneducational young child-oriented programs (adjusted odds ratio, 0.4; 95% confidence interval, 0.1-0.98) and 14.7% of school-age/teenage/adult-oriented programs (adjusted odds ratio, 0.2; 95% confidence interval, 0.1-0.3). Among coviewed programs with educational content, mothers reported interactions during 62.7% of exposures. Coviewing was not reported more frequently for educational young child-oriented programs. CONCLUSIONS: We found limited verbal interactions during television exposure in infancy, with interactions reported for less than one-quarter of exposures. Although interactions were most commonly reported among programs with educational content that had been coviewed, programs with educational content were not more likely to be coviewed than were other programs. Our findings do not support development of infant-directed educational programming in the absence of strategies to increase coviewing and interactions

OBJECTIVE: To determine whether mothers with plans related to shared reading and baby books in the home at the time of delivery of their newborns would be more likely to engage in shared reading behaviors at age 6 months. METHODS: This was a cohort study with enrollment after birth and follow-up at 6 months in an urban public hospital. Predictors included mothers' attitudes and resources related to shared reading during the postpartum period. Outcomes included mothers' shared reading activities and resources at 6 months, as assessed by the StimQ-READ measure. RESULTS: A total of 173 mother-infant dyads were assessed. In multiple regression analyses adjusting for sociodemographics and maternal depression and literacy, StimQ-READ score at 6 months was increased in association with all 3 postpartum predictors: plans for reading as a strategy for school success (adjusted mean 1.7-point increase in 6-month score; 95% confidence interval [95% CI], 0.3-3.0), plans to read in infancy (3.1-point increase; 95% CI, 1.6-4.6), and having baby books in the home (2.3-point increase; 95% CI, 0.9-3.6). In multiple logistic regression analysis, mothers with 2 or more attitudes and resources had an adjusted odds ratio of 6.2 (95% CI, 2.0-18.9) for having initiated reading at 6 months. CONCLUSIONS: Maternal attitudes and resources in early infancy related to shared reading are important predictors of reading behaviors by 6 months. Cumulative postnatal attitudes and resources are the strongest predictors of later behaviors. Additional research is needed regarding whether guidance about shared reading in early infancy or pregnancy would enhance programs such as Reach Out and Read

OBJECTIVE: We performed a randomized, controlled trial to assess the impact of the Video Interaction Project (VIP), a program based in pediatric primary care in which videotaped interactions are used by child development specialists to promote early child development. METHOD: Ninety-nine Latino children (52 VIP, 47 controls) at risk of developmental delay based on poverty and low maternal education were assessed at age 33 months. VIP was associated with improved parenting practices including increased teaching behaviors. RESULTS: VIP was associated with lower levels of parenting stress. VIP children were more likely to have normal cognitive development and less likely to have developmental delays. CONCLUSION: This study provides evidence that a pediatric primary care-based intervention program can have an impact on the developmental trajectories of at-risk young preschool children
