Objective: French norms for the Booklet Category Test (BCT) were presented in a publication by DeFilippis and McCampbell in 2002. They were stratified by age and education for the 506 subjects in the normative sample. However, the norms were never analyzed statistically to determine if they differed from the US sample in Heaton, et al's 2004 publication. The present study statistically compared the two normative samples to determine if there were differences in the performances of the groups. Method: The BCT was administered according to the test manual to 506 neurologically healthy volunteers, aged 20 - 80 years. Education in years was less than 12 years to 15 years. Data from the French sample was stratified by age and education, as well as by levels of impairment indicated by test scores. The error scores for each age and education level for the French sample was compared to the corresponding US sample, utilizing t scores. The percentages of scores at different levels of performance for the two samples were compared, utilizing a chi-square statistic. Results: No significant differences were found comparing the French to the US norms, either for overall scores or for levels of performance (p > .10 for all analyses). Conclusion: It appears that the BCT is not affected significantly by cultural differences in French vs US culture. Thus, this analysis supports the opinion that the test can be used in cultures that are similar to Western societies. The need for additional normative data sets for use of the test in other similar societies, such as other European countries, is lessened by these results. However, use of the test in cultures that are very different from that present in the US and other Western countries need to be examined with statistical analyses similar to what was presented here.
