Book-Sharing for Toddlers with Clefts (BOOST): Protocol for a randomized controlled trial of a remote intervention to promote language development in children with cleft palate.

BACKGROUND: Children with cleft palate, with or without cleft lip (CP±L), exhibit language delays on average compared to children without clefts. Interventions to address these disparities are scarce. In this multi-center study, Book Sharing for Toddlers with Clefts (BOOST), we will test a remote, parent-focused intervention to promote language development in children with CP±L. OBJECTIVES: The study will test two primary hypotheses. First, toddlers randomized to BOOST will exhibit better language outcomes than children receiving standard-of-care (SOC). Second, we hypothesize that the BOOST program's effect on language outcomes is mediated by the frequency and quality of parent-child reading interactions. METHODS: The study is a randomized-controlled trial comparing the BOOST group to a SOC comparison group. We will enroll N = 320 English and/or Spanish-speaking children ages 24-32 months with isolated CP±L (n = 160 per group). Both groups will receive children's books, and parents will record and upload videos of themselves reading the books with their children using a smartphone app developed for the study. Parents will also complete surveys asking whether they read to their children on five randomly selected days each week. In addition, the BOOST group will participate in 3 remote dialogic book-sharing intervention sessions via Zoom. We will code book-sharing videos to assess parents' target skill usage and children's expressive language. End-of-study assessments will include measures of child language outcomes (e.g., clinician-administered measures, parent reports, and naturalistic child language samples). RESULTS: Enrollment began in April 2024 and will continue through approximately April 2028. CONCLUSION: The BOOST study will address a critical gap in the literature on interventions to improve language in children with CP±L. The results will inform the care for toddlers with oral clefts and have potential applications for other populations.

A Comparative Analysis of the Full and Short Versions of the Social Responsiveness Scale in Estimating an Established Autism Risk Factor Association in ECHO: Do we Get the Same Estimates?

PURPOSE: Prior work developed a shortened 16-item version of the Social Responsiveness Scale (SRS), a quantitative measure of social communication and autism spectrum disorder (ASD)-related traits. However, its properties for use in risk factor estimation have not been fully tested compared to the full SRS. We compared the associations between gestational age (previously established risk factor for ASD) and the 65-item "full" and 16-item "short" versions of the SRS to test the shortened version's ability to capture associations in epidemiologic analyses of ASD risk factors. METHODS: We used data from participants in the Environmental influences on Child Health Outcomes (ECHO) Program (n = 2,760). SRS scores were collected via maternal/caregiver report when children were aged 2.5-18 years. We compared estimates of associations between gestational age and preterm birth between the full and short SRS using multivariable linear regression, quantile regression, and prediction methods. RESULTS: Overall, associations based on full and short SRS scores were highly comparable. For example, we observed positive associations between preterm birth with both full ([Formula: see text]=2.8; 95% CI [1.7, 4.0]) and short ([Formula: see text]=2.9; 95% CI [1.6, 4.3]) SRS scores. Quantile regression analyses indicated similar direction and magnitude of associations across the distribution of SRS scores between gestational age with both short and full SRS scores. CONCLUSION: The comparability in estimates obtained for full and short SRS scores with an "established" ASD risk factor suggests ability of the shortened SRS in assessing associations with potential ASD-related risk factors and has implications for large-scale research studies seeking to reduce participant burden.
