Purpose of Project

To compare the relative efficacy of two comprehensive
programs for treating preschool-aged children with
autism

7/16/2015
High quality TEACCH and LEAP preschool classrooms will
be compared to each other and control classrooms serving
young children with ASD

Brief Description of TEACCH


Treatment and Education of Autistic and related
Communication-handicapped CHildren
Theoretical foundation: Cognitive social learning theory
Key Programmatic Features:





7/16/2015
Self-contained classrooms for children often are used
Adult-structured learning opportunities are used
Classroom environment is arranged based on characteristics of autism
Special education teacher is the primary instructor
Strong parent involvement component

Brief Description of LEAP


Learning Experiences: Alternative Programs for Preschoolers
and Parents
Theoretical Foundation: Blend of ABA and theories of child
development
Key Programmatic Features:





7/16/2015
Typically developing children are full-time class members
Naturalistic teaching strategies are used
Classroom environment mirrors typical early childhood setting
Co-teaching model of instruction
Strong parent training component

Project Overview

Four year, multi-site study involving the following states:




North Carolina (Drs. Sam Odom & Brian Boyd—UNC-Chapel Hill)
Colorado (Dr. Laurie Sperry—UC-Denver)
Florida (Drs. Michael Alessandri & Anibal Gutierrez—University of Miami)
Minnesota (Drs. Frank Symons & Lesley Craig-Unkefer—University of
Minnesota)


Approximately N = 75 preschool classrooms will be involved in
the study
Family and child measures will be collected at Pre-treatment,
Post-treatment, and 6 month follow-up time points to examine


Description of Years 1 – 4

Year 1: Psychometric validation of TEACCH & LEAP
fidelity measures



To ensure the initial and on-going quality of the active
treatment classrooms
To ensure fidelity measures discriminate the comprehensive
models from each other as well as control classrooms
Years 2-4: Collection of child and family data

7/16/2015
Booster teacher training sessions will be provided for
teachers involved in the study prior to starting data collection

6.
What are the immediate and relative treatment effects of the TEACCH, LEAP, and
control classroom models on the developmental performance of preschool-age
children with ASD?
What are the longitudinal treatment effects of the three modes of treatment on the
subsequent social, communication, and adaptive performance of children ASD after
they transition to their next educational setting?
What are the relative, immediate and long-term effects of the three modes of
treatment on families of young children with ASD?
Are there child characteristic variables associated with response to treatment for the
three modes of treatment?
Are there variables that mediate and moderate the relative treatment effects for
young children with ASD?
What are the relative costs of LEAP, TEACCH, and standard eclectic services for
children with autism and their families?
