Psychometric Properties of the Arabic Version of the Pain Resilience Scale among Lebanese Adults with Chronic Musculoskeletal Pain.

ABSTRACT

Background: The Pain Resilience Scale (PRS), which measures behavioral perseverance and the ability to regulate emotions and cognition despite ongoing pain, lacks an Arabic version. Objectives: This study aimed to translate, culturally adapt, and validate an Arabic version of the Pain Resilience Scale (PRS-A) among Lebanese adults. Methods: Phase 1 involved translation and cross-cultural adaptation of the PRS into Arabic. Phase 2 examined the reliability and validity of the PRS-A. A convenience sample of 154 Lebanese adults with chronic musculoskeletal pain completed the PRS-A and self-report measures of pain catastrophizing, pain self-efficacy, pain intensity and interference, depression and anxiety, and quality of life. Results: The PRS-A yielded a two-factor structure with factor 1 representing "cognitive/affective positivity" and factor 2 representing "behavioral perseverance," accounting for 41.93% and 15.15% of the variance in pain resilience, respectively. Total PRS-A score (M = 33.20 and SD = 9.90) showed significant correlations with pain catastrophizing (M = 27.65, SD = 13.03, and r = -0.52), pain self-efficacy (median = 9.00, IQR = 4, and rho = 0.61), pain intensity (M = 4.50, SD = 2.25, and r = -0.28), pain interference (M = 4.30, SD = 2.89, and r = -0.56), physical (M = 34.95, SD = 9.52, and r = 0.34) and mental (M = 40.08, SD = 12.49, and r = 0.58) health functioning, anxiety (median = 7.00, IQR = 7, and rho = -0.57), and depression (median = 4.00, IQR = 6, and rho = -0.58). PRS-A subscale was also significantly related to all measures except pain intensity, which was correlated with cognitive/affective positivity (r = -0.33) but not behavioral perseverance (r = -0.09). Cronbach's alpha for the PRS-A was 0.87. Conclusion: The PRS-A demonstrated validity and acceptable reliability among Arab-speaking individuals with chronic musculoskeletal pain, suggesting its potential utility for assessing pain resilience within this population.
