Self-administered alcoholism screening test (SAAST): comparison of classificatory accuracy in two cultures

Results of stepwise discriminant analyses of the Self-Administered Alcoholism Screening Test (SAAST) administered to 181 alcoholics and 123 nonalcoholics in Mexico City were compared with results of a similar analysis of a sample in the United States (Rochester, MN). With sensitivities of 90% and 95%, specificities were 91.1% to 99.2% in the Mexican sample for total score and a nine-item version derived from the Mexican sample gave specificities between 95.1% and 99.2% at 90% and 95% sensitivities, as with the Rochester sample. The two items with greatest predictive power were the same in both cultures.
