Feasibility, Surface and Content Validity of the Integrated Palliative care Outcome Scale (IPOS) for Non-cancer Patients

Abstract

Purpose: To examine the feasibility of the Integrated Palliative care Outcome Scale (IPOS), a comprehensive palliative care scale, for non-cancer patients. Methods: Twenty non-cancer patients and 20 healthcare providers who provide care to the participating patients were asked to complete the IPOS questionnaire, and cognitive interviews were conducted with them. The interviews were analysed using content analysis, a qualitative analysis method. Results: About half to 90% of both patients and healthcare providers answered that they did not find it difficult to answer or understand all items of the IPOS. Therefore, we confirmed its surface validity, and the content validity of the IPOS was confirmed. Conclusion: The surface validity and content validity of the IPOS for non-cancer patients were confirmed, and it became clear that the IPOS can be used as a comprehensive assessment tool for the palliative care of non-cancer patients.
