American Journal of Audiology
|May 10, 2014
Summary
A new Tinnitus Primary Function Questionnaire effectively measures tinnitus impact on daily life, showing significant improvement after treatment. This tool aids in assessing treatment efficacy for tinnitus patients.
Area of Science:
- Audiology
- Otolaryngology
- Psychology
Background:
- Tinnitus significantly impacts quality of life, affecting emotions, hearing, sleep, and concentration.
- Existing questionnaires may not fully capture the primary functional impairments caused by tinnitus.
- Developing a sensitive measure is crucial for evaluating treatment effectiveness.
Purpose of the Study:
- To develop and validate a questionnaire targeting primary activities impaired by tinnitus.
- To create a tool more sensitive to treatment effects than existing measures.
Main Methods:
- Developed questions across four domains: emotions, hearing, sleep, and concentration.
- Administered a 20-item questionnaire to 158 tinnitus patients.
- Utilized factor analysis to refine the questionnaire to 12 items representing four independent domains.
Main Results:
- The 12-item Tinnitus Primary Function Questionnaire demonstrated validity and reliability.
- Scores correlated significantly with established measures like the Tinnitus Handicap Questionnaire, sleep quality, and anxiety levels.
- A notable reduction in average scores from 51% to 38% was observed post-treatment, indicating sensitivity to change.
Conclusions:
- The Tinnitus Primary Function Questionnaire is a valid, reliable, and sensitive instrument.
- It is suitable for assessing the efficacy of tinnitus treatments in clinical trials.
- The questionnaire provides a focused measure of tinnitus-related functional impairment.
