Improving Children's Expressive Language and Auditory Comprehension Through Responsive Caregiving: Evidence from a Randomized Controlled Trial of a Strength-Based Video-Coaching Intervention.

Abstract

Young children from low-SES backgrounds are at higher risk for delayed language development, likely due to differences in their home language environment and decreased opportunities for back and forth communicative exchange. Intervention strategies that encourage reciprocal caregiver-child interactions may effectively promote young children's language development and enhance optimal language outcomes. The Filming Interactions to Nurture Development (FIND) program is a brief strength-based video-coaching intervention designed to promote increased back and forth ("serve and return") interactions between caregivers and their children. The current study used data from a randomized controlled trial (RCT) to examine the effectiveness of the FIND program in improving auditory comprehension and expressive communication skills among children from low-SES backgrounds. The current study used a pretest-posttest design to evaluate intervention effects from an RCT with 91 low-SES families. Families with children aged 4 to 36months old (41.8% female) were randomly assigned to an active control or FIND intervention group. Children's auditory comprehension and expressive communication were assessed using the Preschool Language Scales, Fifth Edition (PLS-5) during both pre- and post-intervention sessions. Children in the FIND intervention group showed significantly increased expressive communication skills and a non-significant increase in auditory comprehension skills across the intervention period. In contrast, children in the active control group showed non-significant changes in expressive communication and a statistically significant decline in auditory comprehension abilities between pre- and post-intervention assessments. All analyses controlled for sex, age, and home language. This study provides preliminary evidence that the FIND intervention promotes the development of expressive and receptive language skills among young children in high-stress, low-SES environments.
