Evaluation of psychometric properties of Walking Impairment Questionnaire in overweight patients with osteoarthritis of knee

Eileen Collins, PhD, RN, et al.

This study examined the psychometric (measurement) properties of the Walking Impairment Questionnaire
(WIQ) in patients with osteoarthritis (OA) of the knee. A total of 105 patients completed the WIQ. Internal
consistency of the WIQ was supported. Scores were consistent when patients were tested 14 days apart. The relationships were moderate between the WIQ subscales and other established measures such as the 6-minute walk distance, stair climb and descend, and the Western Ontario and McMaster Universities OA Index. After evaluating the psychometric properties of the WIQ, we concluded that it is a valid and reliable instrument to use in patients with OA of the knee.
