Summary
The Spanish Tinnitus Handicap Inventory (THI) is a reliable tool for assessing tinnitus impact. This validated questionnaire accurately measures functional, emotional, and catastrophic effects on quality of life.
Area of Science:
- Audiology
- Otolaryngology
- Health Psychology
Background:
- Tinnitus is a prevalent auditory condition affecting quality of life.
- Standardized tools are needed for tinnitus handicap assessment.
- The Tinnitus Handicap Inventory (THI) is a widely used measure.
Purpose of the Study:
- To validate the Spanish version of the Tinnitus Handicap Inventory (THI).
- To evaluate the psychometric properties of the Spanish THI for clinical use.
Main Methods:
- Translation and retrotranslation of the original THI into Spanish.
- Administration of the Spanish THI to 80 tinnitus patients.
- Assessment of internal consistency and reliability using Cronbach's alpha.
Main Results:
- The Spanish THI demonstrated high reliability and internal consistency (Cronbach's alpha = 0.90).
- Subscales (functional, emotional, catastrophic) also showed strong psychometric properties.
- The adapted THI effectively captured the impact of tinnitus.
Conclusions:
- The Spanish adaptation of the THI is a valid and reliable instrument.
- It is suitable for clinical settings to quantify tinnitus-related quality of life impacts.
- Facilitates consistent tinnitus handicap evaluation in Spanish-speaking populations.
