Abstract

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.

Keywords: CPAQ-8; assessment; chronic pain; pain acceptance; psychometric properties.
