Trial Outcomes & Findings for Maximizing Outcomes for Preschoolers With Developmental Language Disorders (NCT NCT03782493)
NCT ID: NCT03782493
Last Updated: 2026-08-19
Results Overview
The language sample is a structured protocol designed to elicit child language. The number of different verbs used during the language sample is indicative of the child's grammar skills, with more verbs reflecting stronger grammar skills.

Enhanced Milieu Teaching-Sentence Focus
The study intervention is a behavioral intervention which will include individually teaching caregivers to use the intervention strategies from the Enhanced Milieu Teaching-Sentence Focus (EMT-SF) intervention using a manualized protocol (Teach-Model-Coach-Review). Caregivers will participate in 66 intervention sessions across 18 months, targeting vocabulary and grammar as well as the transition to decontextualized language.
the Enhanced Milieu Teaching-Sentence Focus: Caregivers in the treatment group (EMT-SF) will receive 66 EMT-SF intervention sessions at home over 18 months. They will be taught the intervention strategies using a manualized protocol (Teach-Model-Coach-Review).

Business-as-usual Control
Caregivers in the control group will participate in community-based intervention services and receive the same printed intervention instructions, books, and toys at the same intervals as the treatment group, but will not receive EMT-SF intervention.

Enhanced Milieu Teaching-Sentence Focus
n=53 Participants
The study intervention is a behavioral intervention which will include individually teaching caregivers to use the intervention strategies from the Enhanced Milieu Teaching-Sentence Focus (EMT-SF) intervention using a manualized protocol (Teach-Model-Coach-Review). Caregivers will participate in 66 intervention sessions across 18 months, targeting vocabulary and grammar as well as the transition to decontextualized language.
the Enhanced Milieu Teaching-Sentence Focus: Caregivers in the treatment group (EMT-SF) will receive 66 EMT-SF intervention sessions at home over 18 months. They will be taught the intervention strategies using a manualized protocol (Teach-Model-Coach-Review).

Business-as-usual Control
n=52 Participants
Caregivers in the control group will participate in community-based intervention services and receive the same printed intervention instructions, books, and toys at the same intervals as the treatment group, but will not receive EMT-SF intervention.

Timeframe: Assessed when participants were 49 months oldThe Renfrew Bus Story-North American Edition (RBS-NA) is a narrative assessment in which children listen to a story while viewing a picture book and then retell the story. The Renfrew Bus Story Information Score (Min = 0, Max = 56) represents the inclusion of story details during the retell task, with higher scores indicating stronger narrative retell skills.

Timeframe: Assessed when participants were 49 months oldThe CBCL is a caregiver-report questionnaire that measures problem behaviors, including those directed inwardly (i.e., internalizing problems) and those directed outwardly (i.e., externalizing problems). The CBCL yields an Internalizing Problems T-Score (M = 50, SD = 10), with lower scores indicating fewer internalizing problems.
