A community-based early intervention program for toddlers with autism spectrum disorders.

This study examined Pathways Early Autism Intervention, a community-based, parent-mediated, intensive behavioral and developmental intervention program for children with autism spectrum disorders that could be used as a model for state-funded early intervention programs. A single-subject, multiple-baseline, across-participants design was used. Four boys with autism spectrum disorder and their mothers participated. Interventionists made weekly home visits and worked with caregivers to establish and maintain face-to-face reciprocal social interaction and eye contact. Each session included a 10-min video of parent-child interaction. Evidence of intervention effectiveness was measured by percentage of nonoverlapping data points. Social validity was measured using questionnaire items in regard to parents' perception of the intervention. The intervention was effective for the measures of eye contact, social engagement, and verbal reciprocity but not for nonverbal turn taking. Parents perceived the intervention as beneficial and easy to learn and incorporate into daily life.
