Abstract
Background/aims: Outcome measures amenable for palliative care patients in China have been lacking. The Integrated Palliative care Outcome Scale is a brief and valid PROM that evaluates the most burdensome concerns and has been used with advanced cancer patients and adapted to many cultures. The study aimed to evaluate the psychometric properties (validity, reliability, and responsiveness to change) of the Integrated Palliative care Outcome Scale in China.
Methods: A multi-centre validation study was conducted to test the psychometric properties of the Chinese Integrated Palliative care Outcome Scale - both (1) patient self-report and (2) staff proxy-report versions. We tested construct validity (factor analysis and correlational analysis), reliability (internal consistency, test-retest reliability and inter-rater reliability), and responsiveness (through longitudinal evaluation of change).
Results: Three hundred eight inpatient adults with advanced cancer were consecutively recruited from two medical oncology units in China. We confirm a three-factor structure (Physical Symptoms, Emotional Symptoms/Communication, and Practical Issues). Good convergent validity to hypothesised items and subscales of the Edmonton Symptom Assessment System is demonstrated. The Integrated Palliative care Outcome Scale shows good internal consistency (α = 0.83) and acceptable to good test-retest reliability (κw=0.59) and inter-rater reliability (κw=0.48). Longitudinal validity in the form of responsiveness to change is good.
Conclusions: The Chinese Integrated Palliative care Outcome Scale is a reliable and valid outcome measure for use in patients with advanced cancer and available in both patient self-report and staff proxy-report versions. It is suitable for assessing needs, symptoms and concerns in advanced cancer, monitoring the change of health status over time, determining the impact of healthcare interventions, and demonstrating the quality of care.
