Introduction: The measurement of pain coping allows establishing relationships with functionality, verifying treatment effectiveness and efficacy, and assessing changes over time. One of the most globally used instruments for measuring pain coping is the Chronic Pain Coping Inventory (CPCI). However, Brazilian studies validating this instrument are still necessary. Objective: to test the construct validity of the Brazilian version of the Chronic Pain Coping Inventory in adults/elderly individuals with chronic pain through hypothesis testing. Method: methodological study of construct validation of the CPCI-Brazilian Version, with a sample of 705 adults/elderly individuals with chronic pain. The CPCI scales were correlated with the Center for Epidemiologic Studies – Depression (CES-D), Roland Morris Disability Questionnaire (RMDQ), Brief Pain Inventory (BPI), and the Abbreviated Quality of Life Assessment Instrument - WHOQOL-BREF using hierarchical multiple regression blocks. Results: the highest contribution of CPCI scores was in explaining physical dysfunction in individuals with chronic pain (27%). The scales that fully confirmed the theoretical model were task persistence, seeking social support, guarding, and resting. Conclusion: we confirmed the construct validity of the CPCI and the importance of assessing pain coping, especially those related to predicting physical dysfunction, avoidance, and fear of pain. The confirmation of correlation between CPCI scales and measures of physical and psychological functionality supports the management of chronic pain from a cognitive-behavioral perspective, recognized as effective in non-pharmacological pain treatment.
