Persons with mental illness often struggle to meaningfully participate in decisions about their services. This study engaged persons with mental illness to understand how health information could empower them. Participants reported wanting information on diagnoses, medications, symptoms, and strengths as well as clinician notes and rationale. The Resident Assessment Instrument for Mental Health contains this information and is mandated in in-patient psychiatry. Its findings could be summarized and shared with individuals to promote and facilitate shared decision-making.
