“…Because ADevD may be relatively less articulate than typically developed adults, their perspectives may be expressed and enacted through interactions that include their support-providing family members (e.g., Lashewicz, Mitchell, Salami, & Cheuk, 2014; Lloyd, Gatherer, & Kalsy, 2006). Indeed, researchers, human service agencies, and practitioners (e.g., social workers, psychologists) often rely on family members to facilitate and represent the needs, lifestyle planning, and decisions of ADevD (e.g., Hutcheon, Noshin, & Lashewicz, 2017; Lashewicz et al, 2014). Yet we know little about the processes by which decision making is shared between ADevD and their family members and how ADevD exercise autonomy over their needs, preferences, and decisions.…”
