Indicator-coded versus ordinal race/ethnicity variables in the Meyers neuropsychological battery: a proof-of-concept comparison

Key Points

• This research aims to evaluate the predictive power of indicator-coded versus ordinal race/ethnicity variables in a neuropsychological battery.
• Comparison of race/ethnicity variable coding in neuropsychological assessments.
• Analysis focused on demographics and their predictive strength.
• Utilized the Meyers neuropsychological battery for evaluation.
• Overall, race/ethnicity was a weak predictor of neuropsychological test outcomes when demographics were controlled.
• Systematic prediction biases were identified for specific measures.
• The indicator-coded framework may better accommodate mixed racial/ethnic backgrounds, though not tested in this study.
