Abstract

Background: Acceptance and commitment therapy (ACT) is one of the evidence-based therapies for chronic pain. One of the measuring tools used in this approach is the Chronic Pain Acceptance Questionnaire (CPAQ). The aim of the present study was to determine the psychometric properties of the CPAQ in a sample of patients with chronic pain in Isfahan, Tehran, and Yazd, Iran.

Methods: This was a cross-sectional, methodological study. The statistical population included all Iranian patients with chronic pain. The sample consisted of 228 patients with chronic pain; the patients were simultaneously selected from medical centers affiliated to Isfahan University of Medical Sciences, Baqiyatallah Hospital in Tehran, and the Medical Clinics in Yazd. To determine the validity of the CPAQ, the Pain Disability Index (PDI), Pain Catastrophizing Scale (PCS), Pain Anxiety Syndrome Scale (PASS-20), and Satisfaction with Life Scale (SWLS) were used. SPSS software and correlation analysis methods, confirmatory factor analysis, and Cronbach's alpha were used.

Results: The reliability of the CPAQ was determined to be 0.79 using Cronbach's alpha method, and its validity was confirmed through inverse correlation with the scores of the PDI (-0.319), PCS (-0.228), PASS (-0.355), and SWLS (0.19); all correlation coefficients were significant (P < 0.01).

Conclusion: The validity and reliability of the CPAQ in Iranian patients with chronic pain have been confirmed. Thus, it can be used as a research tool for the measurement of acceptance index and commitment therapy outcome in Iranian patients.
