Development and validation of a geriatrics knowledge test for primary care residents.

This study reports the development and preliminary validation of an instrument to measure geriatrics knowledge of primary care residents. A 23-item test was developed using questions selected from the American Geriatrics Society's Geriatrics Review Syllabus. Ninety-six internal medicine and family practice residents, 14 geriatrics fellows, and 11 geriatrics faculty members participated in the study. Findings support the reliability (Cronbach's alpha = 0.66) and validity (content and "known groups") of this short test. Predictive validity and sensitivity of the test to changes in knowledge will have to be further explored as residents progress through their training.
