Objective: To examine the psychometric properties of the Northwick Park neck pain questionnaire (NPQ) by translating it from English to Hindi and evaluating its content validity (CV) and internal consistency to assess its feasibility for assessing neck pain. Materials and. Methods: This cross-sectional study included 60 patients who had been experiencing non-inflammatory neck pain for at least 4 months. The psychometric properties, internal consistency, and test-retest reliability of the back-translated version were assessed and compared with the original English version. A panel of six experts validated the instrument for CV. Results: The factor analysis revealed a three-factor structure, which accounted for 76.7% of variance in the translated Hindi version of the NPQ. Internal consistency was indicated by a Cronbach's alpha of 0.936, and test-retest reliability was assessed using an intraclass correlation coefficient of 0.935 (95% confidence interval: 0.906-0.958). Significant correlations were found between the individual items of the translated Hindi and original English NPQs. Conclusion: The English-to-Hindi-translated NPQ demonstrated a good factor structure and exhibited similar psychometric properties to the original English version. Therefore, it can be recommended for use in neck pain research in India.
