Hindi Translation, Validation and Test- Retest Reliability of Neuropathic Pain Questionnaire(NPQ)

The recognition that neuropathic pain syndromes were very common necessitated the development of pain scales specific to neuropathic pain. Recent studies have confirmed the existence of neuropathic pain components in patients with musculoskeletal disorders. English, Turkish, Urdu, Spanish, version of NPQ is available for assessment, but no Hindi version of NPQ is yet available for population who only communicates and understands Hindi language. It is necessary that the questionnaire is understood by the Indian population. In fact, a correct exposition of the items by patients is crucial to obtain correct feedback thus making the questionnaire valid to evaluate patient’s contentment and well being.The purpose of this study is to translate into the Hindi version of the NPQ and to evaluate its validity and reliability. A cross-sectional study.The study method includes the translation of the NPQ in Hindi language from English by 2 translators i.e.T1 and T2 from medical and non-medical background respectively. The recording observer then takes a seat to create a T12 version of the translated questionnaire. The reverse translation from the T12 form to the previous form is now being done. Then, an expert panel analyses all the stages and all of the questionnaire items that the translated form of the questionnaire is free of errors, allowing it to be field tested. Evaluation of content’s validity is done. The pre-final form is then fully tested on patients, and the scale’s validity is reported. Finally, the translated questionnaire version will be analyzed by the ethics committee.
