We are conducting a randomized clinical trial (RCT) comparing the 10-week peer-led Photovoice program to services as usual (SAU) at a large publicly funded community mental health agency in Massachusetts. The control SAU condition will be enhanced with a 60-minute peer-led group educational session about understanding and coping with prejudice and discrimination. The 10-session, peer-led Photovoice program, designed to empower individuals with serious mental illness (SMI) to confront public prejudice and discrimination and reduce personal stigma (self-stigma and perceived stigma), was developed and pilot tested at our Center, with primary contributions from staff with a lived experience of mental illness. Development of the Photovoice program was guided by an adaptation of the stress-coping model, informed by recent research and conceptualizations of the effects of stigma on people with SMI. The stress-coping model explicates the mechanisms by which public stigma about mental illness can lead to personal stigma, which in turn has a negative impact on the person's mental health and psychosocial functioning. This model also identifies critical factors that contribute to personal stigma or protect against it, as well as more vs. less adaptive coping responses, that are the primary focus of the Photovoice program.
