Validation and Clinical Adaptation of a Swedish Version of the Tonsil Outcome Inventory-14 Questionnaire.

ABSTRACT:

Purpose

To translate, culturally adapt, and validate a Swedish version of the Tonsillectomy Outcome Inventory-14 (TOI-14) and to evaluate an extended version including three additional sleep-disordered breathing (SDB) items (TOI-17) among adult tonsil surgery patients.

Methods

This prospective multicenter study was conducted across five Swedish ENT departments between 2022 and 2023. One-hundred-and-eight adults scheduled for tonsil surgery and 84 controls without tonsil disease completed the TOI-14, TOI-17, and EQ-5D VAS at baseline and 2 weeks later, and patients repeated the questionnaires 6 months after surgery. Psychometric evaluation included internal consistency, test-retest reliability, convergent and known-groups validity, responsiveness, confirmatory factor analysis
