As noted in the supplement to the U.S. Surgeon General's report on mental health (U.S. Department of Health and Human Services, 2001), overcoming language access barriers associated with limited English proficiency (LEP) should help to eliminate racial and ethnic disparities in mental health care access and quality. Federal policy requires remedial action to overcome language barriers: Under Title VI of the Civil Rights Act of 1964, Medicaid and other federally funded programs must provide assistance to LEP persons. Some state-level public and mental health authorities have responded by instituting "threshold language" policies. The history and terms of federal civil rights policy, and of threshold-language-policy-inspired initiatives, should be understood by everyone concerned with overcoming ethnic disparities in mental health services use. Concerned parties should promote implementation of required measures for language assistance and help to evaluate their implementation and effectiveness.
