A convenience sample of 153 hospital patients with cancer pain was recruited. And the data were analyzed for reliability and validity. Results The adjusted Revised American Pain Society Patient Outcome Questionnaire contains 18 core items, which are easy to understand and can be completed within 10 minutes. Reliability test: the Cronbach α coefficient of internal consistency for the total scale was 0.735. The Cronbach α coefficient of pain intensity dimension was 0.233, the Cronbach α coefficient of sleep interference dimension was 0.891, the Cronbach α coefficient of activity interference dimension was 0.830, the Cronbach α coefficient of emotion dimension was 0.846, the Cronbach α coefficient of pain management related side effects dimension was 0.591, and the Cronbach α coefficient of perception dimension of pain care was 0.633. Validity test: The total content validity of the scale was 0.98, and the content validity of each item ranged from 0.82 to 1.00. Conclusion The adjusted Revised American Pain Society Patient Outcome Questionnaire has good reliability and validity, providing an effective assessment tool for medical institutions to evaluate the quality of cancer pain management.
