Background and Objectives: Many adults with autism spectrum disorders require lifelong reliance on caregiver support. As these caregivers age and experience health challenges, social support can be critical. This study seeks to understand if caregiver health moderates the relationship between informal social support and caregiver burden.; Research Design and Methods: A total of 320 parents (age 50+ years) of adult children diagnosed with ASD were recruited from autism organizations and support groups and completed a web-based survey.
