This qualitative study assessed the experiences of assertive community treatment (ACT) team members regarding the integration of physical and mental health self-management for persons with serious mental illness. Three focus groups elicited information from participants concerning barriers, strategies, and recommendations. Findings from inductive analyses revealed six overarching themes: (1) collaboration with primary care, (2) improvements in engagement, (3) team-focused roles, (4) education and training, (5) recommendations for system level barriers, and (6) systems collaboration. Participant recommendations suggest that ACT teams are well positioned to integrate mental and physical health treatment, but further research is needed to support integrated care.
