Background:
The aim of this study is to observe the application of the Chinese version of Tinnitus Handicap Inventory-China in Tinnitus patients and verify its reliability and validity.
Methods:
About 1129 patients with tinnitus as the first complaint were selected as subjects. The patients were randomly divided into 2 groups: exploration group (n = 565), whose data were analyzed with reliability analysis method using Statistical Package for the Social Sciences software 19.0, validation group (n = 564), whose data were analyzed with validity analysis method using AMOS21.0.
Results:
(1) Reliability test: The Cronbach's α coefficients of the Tinnitus Handicap Inventory-China scale in both groups were 0.94, among which, the Cronbach's α coefficients of functional factor (F), emotion factor (E), and catastrophic factor (C) in group E were 0.87, 0.90, and 0.78, respectively. The half-reliability of the 2 components is 0.87. The correlation coefficient between items and the scale in group E and group V is 0.36-0.78 and 0.33-0.77, respectively. (2) Content validity: The Kaiser-Meyer-Olkin value of group E is 0.96, a total of 4 common factors were extracted, and the cumulative interpretation rate is 57.844%. The number of factors with load less than 0.4 on the 4 common factors is only 1 (F24), suggesting that this factor had little significance; the number of factors with load more than 0.4 on the 2 common factors is 8 (F1, E6, F9, C11, F15, E21, E22, and C23), suggesting that patients had different understandings of these 8 questions. (3) Structural validity: The root mean square error of approximation value of the AMOS structural model in group V is 0.065, and the root mean square residual value is 0.114, indicating low fitness; the NC value is 3.353, indicating good fitness of the scale, but it still needed to be simplified.
Conclusion:
The Chinese version of Tinnitus Handicap Inventory-China has a high reliability when applied in China, but the content validity and structure validity are not high, and the clinical practicability needs to be improved.
