The aim of this study was to validate a Dutch translation of the Cardiff wound impact schedule (CWIS), a disease-specific instrument to measure the health-related quality of life (HRQoL) in patients with chronic leg ulcers. To achieve this, the original instrument was translated. A total of 83 patients with chronic lower leg ulcers were included and completed the translated instrument and SF36 at baseline after assessment of their wound severity. Follow-up was performed 1 week after inclusion. The psychometric properties of the instrument were assessed. Construct validity was positively evaluated by an expert panel. Face validity was positively evaluated in a cognitive debriefing of a pilot group. Discriminant validity was assessed by correlating 1-year amputation risk according to the Wound, Ischaemia, foot Infection classification system with the instrument scores. Significant correlation could not be proven. Criterion validity was assessed by correlating domain scores of the instrument with domain scores of the gold standard: SF36. Moderate to high correlation was calculated for most domains of the instrument. Test-retest reliability and internal consistency were evaluated as acceptable. In conclusion, the Dutch translation of the CWIS is a valid and reliable disease-specific instrument to assess the HRQoL in patients with chronic lower leg ulcers.
