Item bias in cognitive screening measures : comparisons of elderly white, Afro-American, Hispanic and high and low education subgroups.
A study of item bias in standard cognitive screening measures was conducted in a sample of Afro-American, Hispanic and non-Hispanic white elderly respondents who were part of a dementia case registry study.
The methods of item-response theory were applied to identify biased items.
Both cross-cultural and high and low education groups were examined to determine which items were biased.
Out of 50 cognitive items examined from six widely used cognitive screening measures, 16 were identified as biased for either high and low education groups or ethnic/racial group membership.
