Questionnaires given to them were translated into their regional language Kannada. Evaluation of the responsiveness, reliability, and validity of the questionnaire was undertaken.Results: The data assessed the reliability of the scales and not validity. The questionnaire was receptive to changes over time; however, the applicability of the European questionnaire in Indian clinical set up was debatable.Conclusions: Our data suggests that the EORTC QLO-H&N35 is reliable and responsive when applied to patients with head and neck cancer in India. Hence, it may be used as a platform to test validity at a multicentric level.
