The Cross-Cultural Neuropsychological Test Battery (CCNB) was developed in response to the growing need for a culturally fair method of assessing cognitive functioning in minority populations. The CCNB includes 11 tests, takes approximately 90 minutes to administer, and has been given to 336 healthy older adults and 90 demented patients from five ethnic groups (African-American, Caucasian, Chinese, Hispanic, and Vietnamese). The participants’ age ranged from 54 to 99 years (M = 74.5, SD = 8.4) and they had from 0 to 22 years (M = 10.2, SD = 4.6) of education. While education contributed significantly to performance on most of the tests, age affected scores on measures of recent memory and psychomotor speed. Ethnicity and language affected scores on measures of attention, category fluency, and visual-spatial functioning. As a whole, the demented patients scored significantly worse than their healthy peers on the entire CCNB. Tests of mental status and recent memory proved particularly useful in discriminating the two groups. Overall, the results demonstrated the effectiveness of the CCNB in identifying cognitive impairment in minority individuals and highlight the importance of considering education, age, and language when interpreting neuropsychological test findings.
