Introduction Canadian occupational therapists are employed as case managers on assertive community treatment (ACT) teams to support community living for individuals with severe and persistent mental illnesses. In this position, occupational therapists act primarily as generalists, typically attending appointments with clients, supervising medication adherence, supporting basic living needs, and managing client crises. Occupational therapists may also provide psychotherapy and coping skill groups, as well as profession-specific practices, such as skills training. Exploring how ACT occupational therapists describe their perceived ideal practice may support transformation in long-standing, occupational therapy practices on ACT teams. Method This qualitative, interpretive description study involved 11 Canadian ACT team occupational therapists in one individual, semi-structured in-depth interview using an interview guide containing open-ended questions. Interview transcripts were analyzed to identify themes pertaining to therapists’ descriptions of their perceived ideal occupational therapy practice on ACT teams. Results Three themes emerged: (a) Engaging in practice “with intention”; (b) Finding the space for occupational therapy practice; and (c) Supporting clients in their recovery to find their best occupational self. Conclusions The findings highlight practice possibilities for occupational therapist working on ACT teams and provide a foundation for advocating for better use of specific occupational therapy practices within community mental health settings.
