Workplace Activity Limitations Scale - British English

Hammond, Alison; Tennant, Alan; Prior, Yeliz; Gignac, Monique

Abstract

The British English version of the Workplace Activity Limitations Scale (WALS) has been psychometrically tested in rheumatoid arthritis (RA), axial spondyloarthritis (axSpA), osteoarthritis (OA) and fibromyalgia (FM). The WALS was forward translated, reviewed by an expert panel and cognitive debriefing interviews conducted, with changes to the WALS made. The WALS was tested with 831 employed participants who completed questionnaires: 267 men; 564 women; 53.5 (SD 8.9) years of age; with condition duration 7.7 (SD 8.0) years. The WALS satisfied Rasch model requirements, and a WALS Rasch transformation table was created. Concurrent validity was strong with the: WLQ-25 (RA rs = 0.78; axSpA rs = 0.83; OA rs = 0.63; FM rs = 0.64). Internal consistency was consistent with group use (α = 0.80 to 0.87). Test-retest reliability was excellent (ICC (2,1) at 0.90 or above. The British-English version of the WALS is reliable and valid and can be used in both clinical practice and research,
