Tinnitus assessment: Chinese version of the Tinnitus Primary Function Questionnaire.

Objective: The aim of this study is to evaluate the Chinese Version of the Tinnitus Primary Function Questionnaire (TPFQ).

Methods: One hundred and sixteen patients who had been suffering from tinnitus for over 3 months were included in this study. Those tinnitus patients were administered the TPFQ, the Tinnitus Handicap Inventory (THI), the Beck Anxiety Inventory (BAI), the Beck Depression Inventory (BDI), and the Pittsburgh Sleep Quality Index (PSQI). Additionally, the magnitude estimate of tinnitus loudness, pure tone audiogram, and tinnitus matching was obtained. The factor structure was measured using the Kaiser-Meyer-Olkin test. The internal consistency was examined using Cronbach's coefficient. The relationships between the TPFQ scores and other measurements were compared using Spearman's rank correlation coefficient.

Results: The Cronbach's of the 20-item version of TPFQ was 0.94, and that of the 12-item version of TPFQ was 0.92. Both the 20- and 12-item versions of TPFQ were significantly correlated with magnitude estimation of tinnitus loudness, THI, PSQI, BDI, and BAI. The average pure tone hearing threshold was significantly correlated with the hearing subscale.

Conclusion: The 20- and 12-item Chinese versions of TPFQ are reliable and valid measures of tinnitus. The TPFQ can be applied to the assessment and management of tinnitus among the Chinese-speaking population.
