A randomized, controlled trial of a home-based intervention program for children with autism and developmental delay.

Objective: This study aimed to (1) investigate whether provision of a home-based program in addition to a center-based program improves development in young children with disabilities and coping abilities of their families and (2) describe the characteristics of children and families who benefit most from the intervention.

Methods: Fifty-nine children, aged 3-5 years, with no cerebral palsy, participated in the study. Half of the group was randomized to receive an additional program in their homes.
