This study, using three waves of U.S. National Alcohol Surveys (1995-2005), examines lifetime alcohol treatment utilization and perceived treatment barriers among Latinos. The sample included 4,204 Latinos (2,178 women and 2,024 men); data were weighted. Analyses were linear and logistic regressions. Controlling for survey year, severity, and other covariates, male gender and English language interview predicted higher utilization generally and Alcoholics Anonymous use specifically; English interview was also associated with institutional treatment. (Effects for gender on general utilization were marginal.) Other predictors of utilization included older age, lower education, greater social pressures, greater legal consequences, greater dependence symptoms, and public insurance. Whereas men and women differed little on perceived barriers, analyses showed greater barriers among Spanish (vs. English) interviewees. Latina women's underutilization of alcohol treatment requires further research but may be partially explained by stigma. Associations between language of interview and treatment utilization imply a need for outreach and culturally sensitive programming.
