Preschool-age children identified as at risk for later reading difficulties can benefit from supplemental, small-group emergent literacy intervention. As such interventions become commercially available and marketed to preschool programs, it is important to understand their impacts when implemented by intended end users under routine conditions. In this study, we examined the effects of the Nemours BrightStart! (NBS!) intervention on children's emergent literacy skills when implemented by teachers and community aides in authentic preschool classrooms. We randomly assigned 98 classrooms to one of three conditions (NBS! teacher-implemented, NBS! community aide-implemented, or control). Children enrolled in these classrooms who met eligibility criteria and were identified as at risk via an early literacy screener (n = 281) completed pretest and posttest emergent literacy assessments; those assigned to NBS! conditions received intervention from their classroom teacher or a community aide affiliated with a local kindergarten-readiness initiative. Intent-to-treat analyses showed no significant impacts of NBS! on any outcome, and an instrumental variable, as-treated approach showed one significant intervention effect on letter writing. Consequently, we did not replicate results of prior highly controlled efficacy trials. Findings have implications for revising the NBS! theory of change, conducting dosage and as-treated analyses, and moving research-based interventions toward scale-up. [ABSTRACT FROM AUTHOR]

The extant literature on implementation fidelity has found mixed evidence for empirically establishing the dimensionality of implementation fidelity. The current study aims to add to this growing body of literature by examining implementation fidelity in a book-reading intervention for young children's caregivers. Caregivers (n = 291) implemented Sit Together and Read 2 (STAR 2) with their preschool-age children. These data indicated that implementation fidelity was determined to be a four-dimensional construct including adherence/dose, quality of delivery, participant responsiveness, and program differentiation. The main findings of this work are twofold: (a) implementation fidelity is a more complex construct than some previous descriptions, and (b) early childhood education research should aim to report on all aspects of implementation fidelity.

Objectives: The aim of our study is to explore the relationships between neighborhood context, perceived social support, and parenting for low-income mothers with young infants. Methods: Data were collected during the first three time points from the Kids in Columbus Study, a 5-year longitudinal study on low-income families. Mother–child dyads (n = 228) were recruited from five Women, Infants, and Children Centers located in a Midwestern Metropolitan area. Data for the present study represents mother–child dyads that had completed time point 1 (infant age birth to 3-months), time point 2 (infant age 4 to 7 months), and 3 (infant age 9- to 12-months old). Results: Social support and neighborhood quality were associated with both maternal perceptions and observed parenting outcomes. Social support positively predicted maternal perceptions of self-efficacy whereas neighborhood quality was positively related to parent involvement. Discussion: Overall, social support and neighborhood quality were related to aspects of parenting in the first year of children's lives. There was no evidence that the association between social support and parenting varied as a function of neighborhood quality. This finding suggests the neighborhood qualities captured in our study do not influence mothers' ability to access social support during infancy. [ABSTRACT FROM AUTHOR]
