Although numerous studies have examined provider–caregiver interactions and their influence on care outcomes, few represent the perspective of the provider or specifically consider occupational therapy practitioners. The aim of this article is to explore the perspectives of occupational therapists regarding interactions with older adult caregivers in geriatric practice settings. The study was conducted using a constructivist grounded theory approach based on data obtained from repeated focus group sessions and subsequent individual reflections. Occupational therapy practitioners interact with older adult caregivers in ways that reflect negotiations about who holds expertise and whose priorities are most relevant in care situations. These interactions are influenced by health care contexts that foreground the needs of the care recipient. A deeper understanding of caregiving as an occupation via a transactional perspective may serve to illuminate complex care situations and optimize therapist–caregiver interactions.
