This article describes a qualitative study that examined how 23 young adults with pervasive support needs and limited functional communication spent their time and how their parents (n = 23) and direct support professionals (DSPs; n = 2) defined meaningfulness in relation to the young adults' experiences. Data were collected through semi-structured interviews with the parents and DSPs. Findings indicated that most of the young adults spent time in their communities, though typically without friends and not engaged in integrated employment. The participants defined meaningfulness according to three dimensions: community participation, individual indicators, and the nature of activities in the young adults' schedules. They also described both episodic and ongoing challenges that hindered their ability to focus on time spent meaningfully. Finally, their definitions, which reflected basic care needs and community participation goals, raised questions related to the awareness, availability, and utilization of services and supports in the adult developmental disabilities system.
