This dissertation study contributes to the research on Latino mental health service utilization by examining the determinants of utilization of mental health services, while considering Latino socio-cultural factors. Using the Andersen Behavioral Model of Health Service Utilization (BMHSU) as a theoretical framework, secondary data analysis was conducted using the National Latino and Asian American Study (NLAAS), a nationally representative household survey, focusing on mental disorders and mental health service utilization. Results indicate that only 9% of the Latino population surveyed, including those with a depressive, anxiety, substance use, and/or behavioral disorder, report having used at least one source of mental health service. The findings highlight the BMHSU determinants of mental health service utilization and the need for research to increase our understanding of the socio-cultural barriers and facilitators to using mental health services among Latinos in the United States.
