This study validated the psychometric properties of the Arabic Chronic Pain Grade (CPG) scale, demonstrating reliability, convergent validity, and construct validity in chronic pain patients. The Arabic version of the CPG scale was found to be a reliable and valid measure of chronic pain dimensions, including pain intensity and pain-related disability, with the potential to expand research and clinical assessment in the Arab world. Further studies are needed for additional validation.
To increase our understanding of chronic pain in clinical and research contexts, an assessment of its dimensions using reliable and valid self-reported pain measures is imperative. However, well-validated Arabic chronic pain assessment scales are lacking. The Chronic Pain Grade (CPG) scale has been used worldwide, yet an Arabic version of the CPG scale has not yet been validated. Thus, we conducted this study to demonstrate the psychometric properties, including reliability, convergent validity, and construct validity of the Arabic CPG scale. A cross-sectional study was conducted in two hospitals in Saudi Arabia. Data were collected from a convenience sample of 233 chronic pain patients. The confirmatory factor analysis showed an excellent fit with the factor structure of the CPG scale and, thus, supported construct validity. The two identified subscales were pain intensity and pain disability. Convergent validity was supported by having significant correlations between the short-form McGill Pain Questionnaire and CPG subscales. Internal consistency reliability was demonstrated, as Cronbach's alpha was 0.916 for pain intensity and 0.815 for pain disability. This study provides evidence that the Arabic CPG scale is a reliable and valid measure of chronic pain dimensions, including pain intensity, and pain-related disability. This Arabic version of the CPG scale has the potential to expand research and clinical assessment in the Arab world. Future studies are required for further validation.
