"It's Stable but Not Stable": A Conceptual Framework of Subjective Housing Stability Definition Among Individuals with Co-occurring Mental Health and Substance Use Disorders.

Despite increasing efforts to improve housing stability, research has largely defined housing stability in a narrow sense and heavily relied on objective measures, such as housing types and housing duration. The present study constructed a conceptual framework for a subjective housing stability definition from the perspectives of individuals with co-occurring mental health and substance use disorders and their behavioral health service providers. Following the principles of grounded theory, we collected and analyzed qualitative data through semistructured interviews with 24 individuals with serious mental illness and substance use problems and three focus groups with 22 behavioral health service providers. We developed a conceptual framework with two domains of subjective housing stability: functional stability and experiential stability. The functional stability domain includes four theoretical concepts: meeting basic needs, housing quality, housing affordability, and housing permanence. The experiential stability domain includes four theoretical concepts: autonomy and independence, connectedness, safety, and supportiveness. The conceptual framework can inform future research, practices, and policies to move beyond focusing on merely providing housing to consider the diverse and underlying needs in improving housing stability and well-being among those experiencing or at risk of housing instability.
