| Annotation | The Short Portable Mental Status Questionnaire (SPMSQ) was developed to assist physicians in determining whether patients are cognitively impaired. This secondary data analysis investigated differential item functioning (DIF) in the SPMSQ across demographic sub-groups. Subjects were 3,954 patients aged 60+ who completed the SPMSQ during routine primary care practice visits. After adjusting for overall cognitive ability, women were more likely than men to respond correctly to name-of-the-place and mother's maiden name items. African Americans were more likely than Whites to correctly give their telephone numbers. Those with 6-8 years of education were less likely to name the current US President or correctly answer the serial threes (subtracting 3 from 20 and then from each subsequent number) items than those with 12 or more years of education. Those aged 80+ were less likely to correctly identify the day of the week than those aged 60-69. Future studies seeking to develop new cognitive screening measures should perform DIF analyses in the instrument development phase to eliminate DIF items a priori. (RH). |
