Summary:The Boston Diagnostic Aphasia Examination Battery (BDAE) is one of the most widely used aphasia tests worldwide. Information about general population performance, however, is limited. This paper analyzes the effects of gender, age, socioeconomic status (SES), academic achievement, and occupation on the BDAE Spanish version. The BDAE was administered to a randomized sample of 156 occupationally active 19-60-year-old participants (75 male and 81 female) from two SES groups. Gender and age had a significant effect on some reading and writing subtests. Body-part naming and mechanics of writing scores were significantly decreased in the low SES group. Education had a significant impact over most of the BDAE subtests. A stepwise regression model showed that academic achievement was best able to predict the variance in BDAE scores with a low (< 15%) to modest (> 17%) but significant capability (F MANOVA p < .01). A factor analysis disclosed 7 factors that explained 67% of the total variance.
