This study tested the psychometric properties of the Walking Impairment Questionnaire (WIQ) in overweight patients with osteoarthritis (OA) of the knee. Internal consistency, test-retest reliability, and concurrent validity of the WIQ were measured. Used in a randomized clinical trial, the WIQ was one of the instruments completed by overweight adults with OA of the knee. A total of 105 patients completed the WIQ. Internal consistency of the WIQ was supported in this population with a Cronbach alpha total score of 0.97. Test-retest reliability scores were not different when subjects completed the WIQ 14 days apart (p > 0.05). 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) questionnaire. After evaluating the psychometric properties of the WIQ, we found that it is a valid and reliable instrument to use in overweight patients with symptomatic OA of the knee.
