The 14-item Paediatric Throat Disorders Outcome Test: a valid, sensitive, reliable, parent-reported outcome measure for paediatric throat disorders.

Objectives: We modified and abbreviated a pre-existing research questionnaire, the Tonsil and Adenoid Health Status Instrument, to make it suitable for rapid completion as a disease-specific, health-related quality of life research tool for children with tonsil and adenoid disease in the UK. We determined the main psychometric properties of the resulting 14-item Paediatric Throat Disorders Outcome Test.

Design, Setting And Participants: Pre- and post-operative questionnaires were completed by the parents of children with throat disorders referred to two large hospitals.
