Can Computer-Adaptive Testing Help Senior Citizens? Research from Boston University suggests it can. Professor Alan Jette, Director of the Boston University Health & Disability Research Institute published a recent paper examining disability assessments in traditional and computer forms. With data from 671 older adults residing in care facilities, CAT compared favorably with fixed-form scales, even for a version of the CAT with only 10 questions. In his study, each CAT was administered in less than three minutes, and were highly correlated with the original instrument.
His research strongly suggests that in situations where time is a scarce resource, and measurement fidelity is still important, that Computer-Adaptive Measurement approaches are often more useful than others.
