Cross-sectional study demonstrates acceptable validity and reliability of the Chinese CompACT scale in nasopharyngeal carcinoma, supporting its utility for evaluating psychological flexibility.
OBJECTIVES: The increasing application of Acceptance and Commitment Therapy (ACT) in oncology suggests that psychological flexibility may be a crucial factor in the treatment of individuals with cancer, rehabilitation and well-being. The Chinese version of the Comprehensive Assessment of Acceptance and Commitment Therapy Processes (CompACT-C) was found to have acceptable reliability and validity among individuals with breast cancer; however, its psychometric properties have not been verified among individuals with nasopharyngeal carcinoma (NPC). METHODS: Convenience sampling was used to recruit participants diagnosed with NPC from a Grade III Level A hospital in Guangdong Province, China. The patients provided general demographic data and completed the CompACT-C and the Acceptance and Action Questionnaire-II (AAQ-II). The construct validity of the CompACT-C was tested using confirmatory factor analysis based on its original three-factor structure, and its internal consistency and 2-week test-retest reliability were evaluated. Convergent validity was determined by analyzing the correlation between the CompACT-C and AAQ-II. RESULTS: < 0.001) in this sample of individuals with NPC. CONCLUSIONS: The CompACT-C demonstrated acceptable reliability and validity for assessing psychological flexibility in individuals with NPC, supporting its use as an assessment instrument in future research.
