The evaluation of the affected aspects of life quality is highly dependent on the subjects’perception. Self-report questionnaires have been used to identify these affected aspects. In the present study, the relationship between the Persian versions of tinnitus functional index (TFI-P) and tinnitus handicap inventory (THI-P) was investigated. Methods: This is a comparative cross-sectional study conducted on 28 hearing-impaired and 27 normal hearing subjects with tinnitus in aged 18−60 years selected according to the inclusion criteria. Both groups completed the TFI-P and THI-P. Results: There was a significant and relatively strong relationship between the total scores of THI-P and TFI-P (r = 0.65) and also between the emotional subscale of TFI-P and the catastrophic subscale of THI-P (r = 0.73). Moreover, there was a moderate relationship between age factor and total score of TFI-P (r = −0.32), and between the cognitive subscale of TFI-P and age (r = 0.40). However, no significant difference was found between hearing-impaired and normal hearing subjects in terms of the total score and subscale scores of TFI-P. Furthermore, we found a significant difference between female and male subjects in terms of the relaxation subscale of TFI-P, and between dura­tion of tinnitus and the quality of life subscale (r = 0.33). Conclusion: The scores of the THI-P and TFI-P questionnaires are related to each other and they can be used for measuring the negative effects of tinnitus. https://avr.tums.ac.ir/index.php/avr/article/view/823
