Community mental health services for ethnic minority groups: a test of the cultural responsiveness hypothesis.

This study investigated services received, length of treatment, and outcomes of thousands of Asian-American, African-American, Mexican-American, and White clients using outpatient services in the Los Angeles County mental health system. It tested the hypothesis that therapist-client matches in ethnicity and language are beneficial to clients. Results indicate that Asian Americans and Mexican Americans underutilized, whereas African Americans overutilized, services. African Americans also exhibited less positive treatment outcomes. Furthermore, ethnic match was related to length of treatment for all groups. It was associated with treatment outcomes for Mexican Americans. Among clients who did not speak English as a primary language, ethnic and language match was a predictor of length and outcome of treatment. Thus, the cultural responsiveness hypothesis was partially supported.
