Abstract

Abstract: Objective: The contribution of neuropathic pain (NeP) in chronic pain conditions is increasingly emphasized with the development of multiple questionnaire‐based measurement scales. The painDETECT questionnaire (PDQ) is a frequently used self‐reported outcome measure to assess NeP in patients with chronic pain conditions in research and regular clinical practice. The aim of the study was to translate and cross‐culturally adapt the PDQ into Hindi (Hi‐PDQ) for use in India and to investigate its psychometric properties. Methods: PainDETECT questionnaire translation into the Hindi language was carried out according to standard guidelines. Patients suffering from chronic pain attending a pain clinic were recruited. Patients completed the Hi‐PDQ at baseline and were retested was conducted after 3 days Exploratory factor analysis (EFA) was carried out to assess the factor structure of the Hi‐PDQ. Measurement properties, including floor and ceiling effects, discriminative validity, and psychometric properties, were also assessed. Results: A total of 160 patients with chronic pain were recruited, including 80 in each NeP and non‐NeP group. The retest was completed in 82 patients. Mean Hi‐PDQ scores were significantly higher in the NeP group compared with the non‐NeP group (20.7 [SD 5.9] vs. 9.9 [SD 5.9]; P < 0.01). EFA revealed a 2‐factor structure explaining 56.9% variance. The Hi‐PDQ was found to have adequate internal consistency (Cronbach's alpha = 0.83), test–retest reliability (intraclass correlation coefficient = 0.94), and excellent discriminant validity (area under the curve = 0.88), with an optimal cutoff value of > 18 (sensitivity and specificity of 82.5% and 91.2%, respectively). Conclusion: The PDQ was successfully translated into the Hindi language. The Hi‐PDQ showed good discriminative validity and psychometric properties. The Hi‐PDQ is a reliable instrument to assess NeP in chronic pain conditions.
