In 2002, the National Institutes of Health sponsored a meeting concerning methodological challenges of research in psychosocial interventions in Autism Spectrum Disorders. This paper provides a summary of the presentations and the discussions that occurred during this meeting. Recommendations to federal and private agencies included the need for randomized(More)
This randomized group experiment compared the efficacy of 2 communication interventions (Responsive Education and Prelinguistic Milieu Teaching [RPMT] and the Picture Exchange Communication System [PECS]) in 36 preschoolers with autism spectrum disorders. Each treatment was delivered 3 times per week, in 20-min sessions, for 6 months. The results revealed(More)
PURPOSE This randomized group experiment compared the efficacy of 2 communication interventions (Responsive Education and Prelinguistic Milieu Teaching [RPMT] and the Picture Exchange Communication System [PECS]) on spoken communication in 36 preschoolers with autism spectrum disorders (ASD). METHOD Each treatment was delivered to children for a maximum(More)
Thirty-five children who received an autism spectrum diagnosis at the age of 2 years (24 with autism, 11 with PDD-NOS) were re-evaluated 2 years later to examine factors related to the development of spoken language. Child variables (play level, motor imitation ability and joint attention) and environmental variables (socioeconomic status and hours of(More)
BACKGROUND This randomized controlled trial compared Hanen's 'More than Words' (HMTW), a parent-implemented intervention, to a 'business as usual' control group. METHODS Sixty-two children (51 boys and 11 girls; M age = 20 months; SD = 2.6) who met criteria for autism spectrum disorders (ASD) and their parents participated in the study. The HMTW(More)
Research over the past 50 years has yielded several promising approaches and many specific intervention techniques designed to enhance the communication and language development of young children with intellectual and developmental delays and disabilities. Yet virtually no systematic research has been conducted on the effects of different treatment(More)
This study tested the effect of a method of facilitating prelinguistic communication on parents' responsivity and children's communication and productive language development. The method involved Responsivity education for the parents and Prelinguistic Milieu Teaching for the children (RPMT). Thirty-nine prelinguistic toddlers with intellectual disabilities(More)
PURPOSE This study examined short-term predictive associations between 5 different types of parent verbal responsiveness and later spoken vocabulary for 32 young children with a confirmed diagnosis of autism spectrum disorder (ASD). METHOD Parent verbal utterances were coded from videotapes of naturalistic parent-child play sessions using interval and(More)
The forms, functions, and complexity of nonverbal communication used by very young children with autism were investigated. Fourteen children with autism were matched to 14 children with developmental delays and/or language impairments on the basis of CA, MA, and expressive vocabulary. Subjects participated in a structured communication assessment consisting(More)
Later-born siblings of children with autism spectrum disorder (Sibs-ASD) are at elevated risk for social impairments. Two putative predictors of later social impairment-measures of responding to joint attention and weighted triadic communication-were examined in a sample of 43 Sibs-ASD who were followed from 15 to 34 months of age. Results revealed that(More)
