Psychometric evaluation of the Chinese version of the revised American Pain Society Patient Outcome Questionnaire concerning pain management in Chinese orthopedic patients.

The present study tested the clinical efficiency (item grouping, internal consistency of the subscales, construct validity, and clinical feasibility) of a widely used pain assessment system, the Mandarin version of the American Pain Society Patient Outcome Questionnaire (APS-POQ-R-C), in Chinese patients. We also attempted to investigate the current quality of pain management provided in orthopedic inpatient units in China and provide baseline data. First, we investigated the test–retest reliability of APS-POQ-R-C. In total, 236 orthopedic patients were evaluated. Our results showed that APS-POQ-R-C has satisfactory internal consistency and construct validity, although some items are not appropriate for orthopedic patients. Test–retest reliability outcomes indicated that APS-POQ-R-C is a satisfactory battery with acceptable validity and reliability, and is therefore recommended for pain management in future studies.
