Objective: To translate and validates the QOLOS questionnaire - Quality of Life for Obesity Surgery. Method: Translation and validation of the qolos. it is a 56-item questionnaire divided into 2 sections: pre- and postoperative which has 36 items and only for the postoperative period has 20 items. Results: we performed the translation, cross-cultural adaptation and back-translation of the instrument, which was released on digital platforms, being answered by 466 participants. The correlation between QOLOS and WHOQOL_BREF was significant and positive. Internal consistency and reliability estimation showed cronbach's alpha similar to the original version. Confirmatory factor analysis (CFA) confirmed the dimensionality and factor structure of the scale. Conclusion: statistical analyzes showed evidence of validity and accuracy.
