Karen Goldrich Eskow, Gregory S. Chasson, Jean Ann Summers have an article at The Journal of Autism and Developmental Disorders titled "The Role of Choice and Control in the Impact of Autism Waiver Services on Family Quality of Life and Child Progress." The abstract:
Home and Community-Based Services (HCBS) Waivers provide support and services to families with a child/youth with autism spectrum disorder (ASD). Research indicates HCBS Waivers are positively related to family quality of life (FQoL) and Child Progress. This study replicated and expanded prior research using propensity score matching of 460 families. Results support prior findings that HCBS waivers have a positive impact on FQoL and aspects of child progress. This study also found that having choices in the selection of services and service providers, as well as control over day-to-day provision of services, strengthened both the child and family impacts of the Waiver services. In addition, the study provides preliminary evidence for psychometric properties of a quick and inexpensive parent-report of ASD severity
