Clinician Perceptions on Literacy Promotion in Pediatric Continuity Clinics

Maximizing the impact of reach out and read literacy promotion:anticipatory guidance and modeling

BACKGROUND

Reach Out and Read (ROR) is a multi-component pediatric literacy promotion intervention. However, few studies link ROR components to outcomes. We examine associations between receipt of (1) multiple ROR components and (2) clinician modeling, a potential best practice, with enhanced home literacy environments (EHLEs) among Latino families.

METHODS

We conducted secondary analyses of cross-sectional enrollment data from a randomized clinical trial at three urban community health centers between November 2020 and June 2023. Latino parents with infants 6-<9 months old were surveyed about ROR component receipt (children's book, anticipatory guidance, modeling) and EHLE (StimQ2- Infant Read Scale). We used mixed models with clinician as a random effect, adjusting for covariates.

RESULTS

440 Latino parent-infant dyads were included. With no components as the reference category, receipt of 1 component was not associated with EHLE. Receipt of 2 components (standardized beta = 0.27; 95%CI: 0.12-0.42) and 3 components (standardized beta = 0.33; 95% CI: 0.19-0.47) were associated with EHLE. In separate analyses, modeling was associated with EHLE (standardized beta = 0.16; 95%CI: 0.06-0.26).

CONCLUSION

Findings support modeling as a core ROR component. Programs seeking to enhance equity by promoting EHLE should utilize such strategies as anticipatory guidance and clinician modeling in addition to book distribution.

IMPACT

Reach Out and Read, a multi-component literacy promotion intervention, leverages primary care to promote equity in children's early language experiences. However, few studies link Reach Out and Read components to outcomes. Among Latino parent-infant dyads, we found that implementation of two and three components, compared to none, was associated with enhanced home literacy environments, following a dose response pattern. Parent report of clinician modeling was associated with enhanced home literacy environments. Literacy promotion programs seeking to enhance equity by promoting enhanced home literacy environments should utilize strategies in addition to book distribution, including anticipatory guidance and modeling, to maximize impact.

A Mixed-Methods Investigation Examining Site-Level Variation in Reach Out and Read Implementation

OBJECTIVE

Reach Out and Read (ROR) is an evidence-based early childhood intervention that has been implemented at scale, yet description of ROR implementation is inconsistent. This study engages implementation science to examine ROR delivery and site-level variation.

METHODS

As part of an ongoing clinical trial, we conducted a mixed-methods study in 3 community health centers (CHCs) that serve low-income Latino families. We integrated quantitative parent survey data, qualitative data from monthly key informant interviews with ROR site leaders over 1 year, and in-depth interviews with 18 additional clinicians. At enrollment, parents reported whether they received a children's book, guidance on reading, and modeling from clinicians. We analyzed quantitative data using descriptive statistics, and qualitative data iteratively engaging emergent and a priori codes drawn from the Template for Intervention Description and Replication Checklist.

RESULTS

Three hundred Latino parents (mean age: 31; 75% ≤HS education) completed surveys. The mean child age was 8 months. Overall, most parents reported receiving a book (84%) and guidance (73%), but fewer experienced modeling (23%). Components parents received varied across CHCs. Two themes emerged to explain the variation observed: 1) differences in the perceived purpose of shared reading and book delivery aligned with variation in implementation, and 2) site-level barriers affected what components were implemented.

CONCLUSION

Because of substantive variation in ROR implementation across sites, systematic descriptions using established frameworks and corresponding measurement to characterize ROR implementation may enhance our understanding of mechanisms underlying ROR's effects, which clinicians and policymakers can use to maximize ROR's impact.
