Multicenter Study Clinical Trial
The Reliability and Validity of the Cantonese Version of the Pain Treatment Satisfaction Scale (ChPTSS) in a Sample of Chinese Patients with Chronic Pain.
The Pain Treatment Satisfaction Scale (PTSS) was developed in a Western context for evaluating patients' satisfaction with pain treatment. Although the instrument was shown to possess good psychometric properties, its reliability and validity among ethnic Chinese has not been examined. This article reports the translation of the English-language version of the PTSS into Traditional Chinese Cantonese (ChPTSS) and the preliminary examination of the reliability and concurrent predictive validity of the ChPTSS. ⋯ Our results offer preliminary evidence for the reliability and concurrent predictive validity of the ChPTSS, which can be applied in Cantonese speaking context.
