Mental Health Services

“Optimizing mental health service utilization to enhance HIV care continuum outcomes and improve quality of life: a discrete choice experimental study among individuals with diverse sociocultural experiences” 

The objective of this project is to elucidate the multilevel (i.e., individual, interpersonal, community, and health care system) barriers and facilitators to current screening, referral and utilization of mental health services among clients in the Miami- Dade Ryan White Program using Copeland et al.’s sociocultural adaptation to the Andersen Behavioral Health Services Utilization model, and to identify client preferences for mental health care system delivery using a discrete choice experiment. We will accomplish these objectives with key informant interviews of providers, in-depth interviews of clients and a discrete choice experiment with clients from the Ryan White Program to determine client preferences for mental health services. Additionally, we will have a community advisory board who will inform our study instruments, help us interpret the data, and provide recommendations for adopting findings.
