Abstract

Abstract: Objective : To describe how the Tinnitus Handicap Inventory (THI) was translated into Polish (THI-POL) and to present psychometric data on how well it performed in a clinical population of tinnitus sufferers. Design : The original version of THI was adapted into Polish. The reliability of THI-POL was investigated using test–retest, Cronbach's alpha, endorsement rate and item–total correlation. Construct validity and convergent validity were also assessed based on confirmatory factor analysis, inter-item correlation and Pearson product-moment correlations using subscale A (Tinnitus) of the Tinnitus and Hearing Survey (THS-POL); divergent validity was checked using subscale B (Hearing) of THS-POL. Study sample : A group of 167 adults filled in THI-POL twice over their three-day hospitalisation period. Results : Test–retest reliability for the total THI-POL scores was strong ( r = 0.91). Cronbach's alpha coefficient for the total score was high ( r = 0.95), confirming the questionnaire's stability. Confirmatory factor analysis (CFA) and inter-item correlation did not confirm the three-factor model. Convergent validity from the Tinnitus subscale of THS showed a positive strong ( r = 0.75) correlation. Divergent validity showed only a moderate correlation. All analyses were statistically significant ( p < 0.01). Conclusions : THI-POL is a valid and reliable self-administered tool, which allows the overall tinnitus handicap of Polish-speaking patients to be effectively assessed.
