Exploring the Experience of Community Participation Among Individuals With Serious Mental Illness.

People with serious mental illness (SMI) encounter restrictions in the quantity of their community participation. Less is known about the quality of their participation. We aimed to explore the relationship between symptoms of SMI and the daily experience (i.e., loneliness and enjoyment) of community participation. We examined daily community participation among people with SMI using ecological momentary assessment surveys. We built multilevel models to examine the associations between symptoms of SMI and loneliness or enjoyment during community participation. Our analysis included 183 people among four participant groups: bipolar disorder ( = 44), major depressive disorder ( = 46), schizophrenia/schizoaffective disorder ( = 40), and control ( = 53). People with schizophrenia engaged in more unstructured activities (e.g., socializing) than people among other groups. Symptom association varied across diagnostic groups. To support tailored intervention development, researchers and practitioners should consider the context of participation and the clinical characteristics of the client.
