Individuals with serious mental illnesses are 2-3 times more likely to experience type two diabetes than the general population, which contributes to reduced life expectancy of 10-25 years. Modifiable lifestyle behaviors, such as physical activity and diet, are potential intervention targets that can improve health outcomes for individuals with or at risk for type two diabetes. Personal, interpersonal, and environmental factors have the potential to influence diet and physical activity. Understanding the influence of these factors on a daily basis is important for the development of interventions that lead to sustainable behavioral changes. Specific objectives include using momentary assessment (ecological momentary assessment, accelerometery, and GPS) to (1) explore the relationship between personal, interpersonal, and environmental and metabolic health behaviors among people with SMI and (2) identify the health-related, community opportunities available to individuals with co-occurring SMI and T2D in order to make recommendations for a peer-facilitated intervention. Methodological Approach: This study proposes (n=80) to use ecological momentary assessment, accelerometery, GPS, and GIS to better understand how daily experiences and environmental resources influences daily engagement in physical activity, sedentary behavior, and dietary behavior. Data will be gathered across multiple systems including: the built and natural environments; psychology and behavior; social and cultural context; physical health and wellness; institutional and home settings; and political and economic systems. Anticipated Outcomes: identifying (1) mechanisms of action to improve health behaviors; and (2) community opportunities to support interventions. Finally, expected products include recommendations for intervention development and publications in peer reviewed journals.
