Translation, Cross - Cultural Adaptation and Reliability of the Gujarati Version of Brief Questionnaire of Smoking Urges (QSU - Brief) and Validation

Introduction: Brief questionnaire of smoking urges (QSU - brief) is one of the very widely used scales to measure of craving in smokers. It was originally developed in English and later was translated to Dutch and Malay languages. The QSU - brief is currently not available in Gujarati language so there is a need to develop a Gujarati version of QSU - brief which can be used by the Gujarati language speaking population, other researchers and even clinicians throughout Gujarat. Aim: To translate and cross - culturally adapt the QSU - brief into the Gujarati language and to test the validity and reliability of this version. Materials and Methods: A two - stage observational study was conducted. The QSU - brief was initially translated to Gujarati language through double forward and backward translation and then it was cross - culturally adapted. The translation and its comparative analysis with the original version was assessed and approved by the experts of the committee formed. The reliability and validity of finalized version of Gujarati QSU - brief was subsequently completed with the sample size of 50 male participants for chronic cigarette smokers. Results: The Gujarati version of the QSU - brief has high internal consistency (Cronbach?s ?=0.809) and test - retest reliability (intra class correlation coefficient=0.896). Conclusion: The translation of the QSU - brief into a Gujarati version was successful in preserving the semantic and measurement properties of the original version and was shown to be valid and reliable in a Gujarati population.
