Empower EI: Comparing Early Intervention Approaches to Improve Communication in Toddlers With Developmental Delays

Обзор

This study is testing three ways to deliver Early Intervention (EI) services for toddlers with developmental disabilities (DD). Children enrolled in EI speech therapy will receive one of three approaches: 1. Therapist Delivered EI: For 28 weeks, the child's speech therapist will work directly with the child to support their communication. 2. Caregiver Coaching EI: For 28 weeks, the child's speech therapist will coach the caregiver on how to support their child's communication. 3. Combined EI Approach + Parent-Led Education Program: For 14 weeks, the caregiver will take part in a parent-led education program while the speech therapist works directly with the child to support their communication. During the next 14 weeks, the speech therapist will coach the caregiver on how to support their child's communication. The goal of this study is to identify which approaches are most effective so that all families can benefit fully from EI services.

Подробное описание

High-quality Early Intervention (EI) during the first three years of life, a period of heightened neuroplasticity, is critical to improving outcomes for children with developmental disabilities (DD). There are two EI approaches that may be effective for supporting child communication and improving family outcomes: 1) caregiver coaching, in which the EI therapist teaches the caregiver strategies to help their child's communication, and 2) caregiver psychoeducation, in which a peer mentor teaches the caregiver about skills and resources that are helpful in supporting their child and family.

The aim of the current clinical trial is to determine which EI approaches are most effective, for which families, and why they are effective. This clinical trial also aims to investigate how therapists are delivering the interventions and to characterize the acceptability and feasibility of these interventions for use in real-world settings.

A total of 1,269 toddlers (approximately equal numbers of Black, Latine, and white children) will be enrolled across community-based EI sites. Families will be directly recruited from participating EI therapists' existing caseloads. Caregiver-child dyads will be randomly assigned to one of three groups:

1. Therapist Delivered EI: For 28 weeks, the child's speech therapist will work directly with the child to support their communication. 2. Caregiver Coaching EI: For 28 weeks, the child's speech therapist will coach the caregiver on how to support their child's communication. 3. Combined EI Approach + Parents Taking Action: For 14 weeks, the caregiver will take part in a parent-led education program (Parents Taking Action) while the speech therapist works directly with the child to support their communication. During the next 14 weeks, the speech therapist will coach the caregiver on how to support their child's communication.

Outcomes will assess both caregiver and child domains, including caregiver use of responsive strategies, caregiver capacity to support the child's needs, and child social communication. The study will also examine moderators (e.g., race) and mediators (e.g., caregiver use of responsive strategies) to identify for whom and why each approach is most effective.

A process evaluation will assess implementation fidelity (quality, dosage, adaptations) and explore how fidelity influences effectiveness outcomes. Feasibility, acceptability, and appropriateness of each approach will be evaluated through surveys and interviews with caregivers and EI therapists.

This study is among the first large-scale comparative effectiveness trials of early intervention approaches conducted in real-world EI settings. Findings will inform EI practices and guide caregivers, therapists, and policymakers in selecting interventions that best meet the needs and preferences of diverse families.

Вмешательства

• Поведенческое Therapist-Delivered Early Intervention Approach
  The therapist-delivered early intervention approach will occur during the child's weekly, hour-long early intervention (EI) sessions. During the sessions, the child's EI speech-language pathologist (SLP) will use responsive strategies directly with the child. Responsive strategies focus on noticing the child's communication and responding with language related to their focus of attention. The SLP will not coach the caregiver during the sessions.
• Поведенческое Caregiver Coaching Early Intervention Approach
  The caregiver-coaching early intervention approach will occur during the child's weekly, hour-long early intervention (EI) sessions. During the sessions, the child's EI speech-language pathologist (SLP) will coach the caregiver to use responsive strategies with their child. Responsive strategies focus on noticing the child's communication and responding with language related to their focus of attention.
• Поведенческое Parents Taking Action
  Parents Taking Action (PTA) will be delivered during weekly, one-hour virtual sessions with the caregiver, separate from the child's early intervention (EI) sessions. PTA is a psychoeducation program implemented by a peer mentor (i.e., a culturally-matched caregiver of a child with a developmental disability). During the sessions, the peer mentor will provide information and guidance on a range of topics (e.g., child development, early intervention systems, special education rights/resources, an
