Difficulties with social interactions and communication that characterize autism persist in adulthood. While social participation in adulthood is often marked by social isolation and limited close friendships, this qualitative study describes the range of social participation activities and community contacts, from acquaintances to close relationships, that contributed to connection from the perspective of 40 autistic adults. Qualitative data from interviews around social and community involvement were analyzed and revealed five main contexts where social participation occurred: vocational contexts, neighborhoods, common interest groups, support services and inclusive environments, and online networks and apps. Implications for practice to support a range of social participation include engaging in newer social networking avenues, as well as traditional paths through employment and support services.
