Literature concur that there is a disparity between epidemiological prevalence and mental health services (MHS) utilization rates for Latino and Asian Americans. This study adapted the behavioral model of health service use to examine factors associated with MHS use among Latino and Asian Americans. The model consists of predisposing, enabling, and need factors. This study used the National Latino and Asian American Study data, including six ethnic groups. The outcome measure for this study was the use of MHS in the past 12 months. Age, sex, and education predicted higher odds of MHS use among Latinos, none of which were significant among Asians. Needs factors were strongly associated with higher odds of MHS use among Latinos and Asians.
