Part of a series of studies designed to lead to policy recommendations to improve mental health services to Mexican Americans in Texas, this monograph explores the availability and accessibility of community mental health centers (CMHCs) throughout the state. In hopes of explaining the underutilization of the centers statewide, the locations of CMHCs in relation to the Mexican American and Anglo population clusters are plotted and the major highways connecting the populations and the centers are traced. Because of the heavy concentration of the state's population in five major metropolitan areas (Houston, Dallas, San Antonio, Fort Worth, and El Paso), a second description of CMHCs in these cities is given in an effort to determine whether ethnicity affects accessibility to the centers. A series of questions examines: (1) locations of services; (2) relation of population clusters to CMHCs; (3) accessibility to the greatest number of people; and (4) locations of centers in relation to Mexican American neighborhoods. Conclusions suggests that statewide accessibility from Mexican American regions to CMHCs is poor; the metropolitan accessibility is somewhat better, but there are hints of a tendency to locate centers in the middle class Anglo neighborhoods. It is suggested that this preliminary study should generate more research into the reality of this descriptive archival research. (Author/JD)
