Summary
A Turkish version of the Tinnitus Handicap Inventory (THI) was developed and validated. This reliable tool accurately assesses tinnitus handicap in Turkish-speaking patients, aiding clinical evaluation.
Area of Science:
- Audiology
- Otolaryngology
- Health Psychology
Background:
- Tinnitus is a prevalent auditory condition causing significant distress.
- Standardized instruments are crucial for evaluating tinnitus severity and impact.
- The Tinnitus Handicap Inventory (THI) is a widely used measure, necessitating culturally adapted versions for diverse populations.
Purpose of the Study:
- To develop and validate a Turkish translation of the Tinnitus Handicap Inventory (THI).
- To ensure the Turkish THI is a reliable and valid instrument for assessing tinnitus-related handicap in Turkish patients.
Main Methods:
- Forward-backward translation and expert committee review for cultural adaptation.
- Administration of the Turkish THI to 110 tinnitus patients.
- Statistical analysis including Cronbach's alpha for internal consistency, ICC for reliability, and validity assessments.
Main Results:
- The Turkish THI demonstrated high internal consistency (Cronbach's alpha = 0.88).
- Excellent test-retest reliability was confirmed (ICC = 0.78-0.90).
- Construct validity was supported through patient analysis by age and tinnitus duration.
Conclusions:
- The Turkish version of the THI is a highly consistent and reliable tool.
- This validated instrument is suitable for evaluating symptoms and handicap in Turkish tinnitus patients.
- Facilitates standardized assessment and management of tinnitus in a Turkish clinical setting.

The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...

In parametric statistics, two fundamental tests stand out for their utility and wide application: the Student's t-test and goodness-of-fit tests. These tests provide researchers with a robust method for drawing insights from data, testing hypotheses, and making informed decisions based on their findings.
