Malignant wounds as a result of cancer are under-recognized for the physical and emotional distress they cause patients and their families. Unfortunately, there is a lack of valid and reliable screening and assessment tools to aid in the management of malignant wounds. This study aims to validate a patient-reported outcome measurement tool, Malignant Wound Assessment Tool - Research (MWAT-R). Eight patients were recruited and interviewed using the cognitive interviewing methodology to validate this tool. Patients' understanding and overall impression of the MWAT-R were explored. Our findings showed that the wording and response options posed challenges for patients in completing the tool. Overall, participants felt that questions captured the key issues related to dealing with a malignant wound and accounted for the patients' perspective. Establishing the content and face validity of the MWAT-R from the patients' perspectives using cognitive interviews has provided further evidence to the validity of this tool.
