A comparison of US-born African-American and African-Caribbean psychiatric outpatients.

This study compares US-born African Americans with African Caribbeans attending an urban psychiatric outpatient clinic on various items pertaining to sociodemographics, psychiatric history, current psychiatric illness, and physical health. A structured chart review was performed on a sample comprised of 135 native-born African Americans and 91 African Caribbeans who had attended the clinic during an 11-year period. A total of 28 clinical variables were examined. Nine clinical variables were found to significantly differentiate the two groups in bivariate analysis, and these were entered along with three demographic control variables into a logistic regression analysis. Seven variables attained significant independent effects. African Americans were differentiated from African Caribbeans on history of greater alcoholic abuse or dependence, presence of more delusions, worse health, longer history of previous outpatient treatment, and greater clinical improvement at 6 months. African Caribbeans were found to have a greater frequency of depression and aggressivity. These data underscore the importance of examining intraracial differences in mental illness as well as pointing to the potential benefits of using intraracial comparisons to interpret interracial analyses.
