One way to measure neck pain is using valid questionnaires. Therefore, this study aimed to translate the Northwick Park Questionnaire (NPQ) into Persian and validate the Persian version. Materials and Methods: The present study is a descriptive one that was conducted in 2021 on workers of a housekeeping service company to validate the Persian version of the NPQ. The Backward-Forward technique was used to validate the questionnaire. Afterward, the questionnaire was distributed among 100 female workers, and the Intraclass Correlation Test (ICC) was used to measure reliability. Data were analyzed using the Spearman and Kappa tests in the SPSS software (version 22). Results: In the validity analysis, Kappa and Spearman coefficients were used to determine the agreement and correlation between the questions. The reliability of the questionnaire using the ICC test was 0.906. Additionally, a significant relationship was found between the overall pain intensity in the questionnaire and all its questions. Conclusion: This study aimed to translate the NPQ questionnaire into Persian, validate the Persian version, and determine its applicability in Iran. The findings showed that the Persian version of the NPQ questionnaire is a valid, reliable, and usable tool for neck pain assessment. M3 10.52547/johe.9.2.120 ER -
