Abstract

Background and Aim: Tinnitus is a common symptom and affects patients differently. The Iowa Tinnitus Primary Function (ITPF) questionnaire evaluates tinnitus in four areas: concentration, emotion, hearing, and sleep. This study aimed to translate and then assess the psychometrics of the ITPF questionnaire.

Methods: This is a cross-sectional and methodological (test construction) study. The questionnaire was translated by the Word Health Organization protocol. The validity and reliability of the questionnaire were assessed. The measured validities were the content, face, and discriminative. The reliability was estimated by internal consistency and test-retest stability. We also measured the effects of age and sex on the questionnaire’s score.

Results: The questionnaire was translated based on the protocol. Each item of the questionnaire was understandable for patients and healthy participants. The face and content validities were confirmed by the patients and specialists, respectively. The score of 10.97 was determined as the cutoff point between patients and healthy participants, with a sensitivity of 86.70% and a specificity of 96.10%. The Cronbach α was found to be 0.958, and the intraclass correlation coefficient was 0.975. No significant effect was observed for age (p=0.314) and gender (p=0.866).

Conclusion: The Persian version of the questionnaire showed high validity and reliability. It could be used in research and clinical settings.
