Abstract
This study aimed to translate the Clinically Aligned Pain Assessment (CAPA) Scale into Turkish, perform its cultural adaptation, and evaluate its validity and reliability in Turkish patients.
This single-center, cross-sectional study included a total of 105 patients with pain lasting at least one week between March 2026 and June 2026. The translation process followed standardized forward-backward procedures. Reliability was assessed using internal consistency and test-retest analysis (n = 68, 48-72 h). Construct validity was evaluated with exploratory factor analysis, and convergent validity was examined using Numeric Rating Scale (NRS).
Of a total of 105 participants, 37 were male and 68 were female with a mean age of 46.90 ± 11.974 (range, 23 to 71) years. In the study, the CAPA-TR showed good internal consistency (Cronbach's alpha = 0.859) and excellent test-retest reliability (intraclass correlation coefficient = 0.959). Item-total correlations were above 0.30 for all items. Floor and ceiling effects were below acceptable thresholds. Exploratory factor analysis revealed a single-factor structure explaining 66.2% of the total variance. No significant correlation was found between CAPA-TR scores and NRS.
Our study results suggest that CAPA-TR is a valid and reliable multidimensional tool for pain assessment in Turkish-speaking patients. It provides a practical and patient-centered approach that may support more comprehensive evaluation of pain in clinical practice.
