Introduction To investigate the validity and reliability of a Turkish version of the Skarzynski Tinnitus Scale (STS) in a Turkish patient group. Material and methods The study was conducted on 143 volunteers aged over 18 years who had complained of tinnitus for at least one month. Confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) were used for construct validity. Criterion validity was analysed by a Spearman’s bivariate correlation test. Reliability analyses were assessed with Cronbach’s alpha internal consistency coefficients and test–retest reliability with McNemar–Bowker and ICC coefficients. Results A new three-factor structure was produced using EFA. The factors were similar to the original study except for Item 14. The STS gave similar measures to the tested Tinnitus Handicap Inventory scale. Nearly all item–total correlations were greater than 0.4, indicating good internal consistency. The internal consistencies of the items were 0.86–0.88; in the test–retest reliability analyses of the sub-scales, ICC scores were 0.90–0.96. Conclusions The Turkish STS can be used reliably in all adults with a symptom of tinnitus. However, because one item in the new structure of the Turkish version is in a different sub-dimension it may necessary to conduct new validation studies.
