Summary
The Danish Tinnitus Functional Index (TFI-Da) questionnaire shows excellent reliability and consistency for evaluating tinnitus. This validated tool is recommended for clinical and research use in Denmark to assess treatment outcomes.
Area of Science:
- Audiology
- Otolaryngology
- Health Psychology
Background:
- Standardized questionnaires are crucial for tinnitus evaluation.
- The Tinnitus Functional Index (TFI) is optimized for assessing treatment outcomes.
- A Danish validation of the TFI is needed for clinical implementation.
Purpose of the Study:
- To validate the professionally translated Danish version of the Tinnitus Functional Index (TFI-Da).
- To ensure the safe implementation of TFI-Da in Danish clinical and scientific settings.
Main Methods:
- 133 adult tinnitus patients completed the TFI-Da.
- Internal consistency was assessed using Cronbach's alpha.
- Test-retest reliability was evaluated with Pearson's correlation.
Main Results:
- TFI-Da demonstrated excellent internal consistency (Cronbach's alpha = 0.96).
- Subgroup analyses also showed acceptable internal consistency (> 0.7).
- High test-retest reliability was confirmed (Pearson's r = 0.848).
Conclusions:
- The Danish TFI (TFI-Da) exhibits high internal consistency and test-retest reliability.
- TFI-Da is recommended as the standard tinnitus questionnaire in Denmark.
- This validation supports its use for evaluating treatment effectiveness.
