Validation of the Dutch version of the Walking Impairment Questionnaire

Abstract

This study shows that the Dutch version of the WIQ using the European metric system is a valid, reliable and clinically relevant instrument for assessing walking impairment in patients with intermittent claudication.

Gender differences following supervised exercise therapy in patients with intermittent claudication

“…22 The WIQ is a questionnaire that is validated for the Dutch language in patients with PAD. 23 The selfadministered revised Dutch version was used in the present study. 23 The WIQ assesses impairment in three domains: walking distance, walking speed, and stair climbing.…”

“…23 The selfadministered revised Dutch version was used in the present study. 23 The WIQ assesses impairment in three domains: walking distance, walking speed, and stair climbing. 24 WIQ scores range from 0 to 1, and lower scores correspond with more severe walking disability.…”

Minimally Important Difference of the Absolute and Functional Claudication Distance in Patients with Intermittent Claudication

“…The validated Dutch version of the WIQ was used. 15,16 Determination of the MID As per current recommendations an anchor based approach as opposed to a distribution based approach was used in estimating the MID, using longitudinal prospective data. 17 An anchor is an external criterion for a meaningful change, and can be based on patient reported outcome measures that have demonstrated MID in the target population.…”

Chinese translation and validation of the Walking Impairment Questionnaire in patients with peripheral artery disease

“…The WIQ is a short, disease-specific questionnaire validated in patients with intermittent claudication to characterize the degree of walking impairment in patients with PAD and as a measure of efficacy for interventions to reduce PAD symptoms. 4,[6][7][8] It takes 5 minutes to administer. It contains four subscales measuring pain severity and three important factors of walking impairment in symptomatic PAD patients: walking distance, walking speed and the ability to climb stairs.…”

“…5 The WIQ has been validated in the English and Spanish lang uages in the United States 4,6,7 and Dutch in The Netherlands. 8 There is a need for measures specifically designed to be used in non-English-speaking countries since cultural groups vary in disease expression. For example, the use of 'standard size living blocks' in the original WIQ as a measure of distance is not a common phenomenon in Asia as a reference for distance.…”
