Support for the Spanish version of the CPAQ-8 as a measure of chronic pain acceptance

Aim and objective To provide evidence regarding the psychometric properties of the Spanish eight-item version of the Chronic Pain Acceptance Questionnaire (CPAQ-8). Method Three hundred adults with chronic pain completed measures of pain acceptance, committed action, fear of movement, anxiety, depression, and health-related quality of life. A confirmatory factor analysis (CFA) of the CPAQ-8 was performed. Reliability and validity were also evaluated. Results The CFA confirmed a two-factor structure. The CPAQ-8 Total and subscale scores showed acceptable-to-good internal consistency. Furthermore, the Total and the Activity Engagement scale scores showed moderate associations with Committed Action scores, supporting construct validity. Both the Total and the two subscale scores showed good criterion validity. Conclusion The findings provide further support for the reliability and validity of the Spanish version of the CPAQ-8 Total and subscale scores.
