OBJECTIVE: To study the validity and feasibility of a computerized version of the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index. METHODS:Thirty patients with osteoarthritis (OA) of the knee completed both a paper and a computerized version of WOMAC in random order. The visual analog scaled version of WOMAC, VA3.0, was used. We studied criterion validity by comparing the paper and computerized versions. RESULTS: All patients completed the computerized version without undue difficulty. Criterion validity, based on aggregated subscale scores, was excellent: Pain, ICC = 0.89, Stiffness, ICC = 0.87, Physical Function, ICC = 0.95. CONCLUSION: The computerized version of WOMAC VA3.0 is a valid alternative to the paper version.
