or baseline visits (N1⁄48525). All subjects were determined to be cognitively intact at the time of RBANS testing. Index score scaling was done based upon the standard North American normative data. Results: There were someminor geographical variations in terms of RBANS total scale score, but this did not appear to be due to any specific cultural/linguistic factors, as there were no meaningful differences in domain-based index score profiles. Index score profiles were normally distributed across countries. Conclusions: The minor overall performance differences across geographic area might be attributable to differences in educational systems, recruiting practices, or a combination thereof. The fact that therewas no difference in the domain-based index score profile across countries suggests that there is no systematic cultural/linguistic bias in the existing translations that would require adjustments.
