Abstract
STUDY DESIGN: Validation of a translated, culturally adapted questionnaire. OBJECTIVE: We developed a Korean version of the Chronic Pain Coping Inventory-42 (CPCI-42) by performing a cross-cultural adaptation, and evaluated its reliability and validity. SUMMARY OF BACKGROUND DATA: The CPCI is widely used and validated instruments for measuring coping strategies in chronic pain. However, no validated and culturally adapted version was available in Asian countries. METHODS: We assessed 142 patients with chronic low back pain using the CPCI-42 and measures of physical disability, pain, and quality of life. Results for 93 of the 142 patients exhibited test-retest reliability. The interval time of collecting retest data varied from 2 weeks to 1 month. Criterion validity was evaluated using correlations between the CPCI-42 and the Oswestry Disability Index, the Brief Pain Inventory, and the Short Form 36-item Health Survey (version 2.0). Construct validity was computed using exploratory factor analysis. RESULTS: The Korean version of the CPCI-42 had a high internal consistency (Cronbach's alpha >0.70) with the exception of results for task persistence and relaxation. Illness-focused coping (guarding, resting, asking for assistance) and other-focused coping (seeking social support) were most significantly correlated with Oswestry Disability Index, Brief Pain Inventory, and Short Form 36-item Health Survey, respectively. Outcomes for task persistence were contrary to other subscales in wellness-focused coping. Construct validity by factor analysis produced similar results to the original CPCI subscale. However, several factors showed cross-loading in 8 factor solutions. CONCLUSION: Despite linguistic and cultural differences, the Korean version of the CPCI-42 is overall a meaningful tool, and produces results sufficiently similar to the original CPCI-42.
