Validation of Screening Questions for Hyperacusis in Chronic Tinnitus

Abstract EN

Background.

We investigated the validity of the two hyperacusis items of the TSCHQ (Tinnitus Sample Case History Questionnaire) from the TRI (Tinnitus Research Initiative) database by comparing them with the German hyperacusis questionnaire GÜF.

Methods.

We investigated the association of the GÜF with the TSCHQ screening questions for both the sum score and the single items with correlation, contrast, principal component, and discriminant analysis in a sample of 161 patients with chronic tinnitus.

Results.

TSCHQ items and the GÜF total score were significantly associated with a special focus on fear and pain related hyperacusis.

Factor analysis of the GÜF revealed the three factors “fear and pain related hyperacusis,” “hearing related problems,” and “problems in quality of life.” A discriminant analysis showed a sensitivity of 64% and a specificity of 71% of the TSCHQ items for the establishment of tinnitus patient subgroups with and without hyperacusis.

Discussion.

Both hyperacusis TSCHQ items can serve as screening questions with respect to self-reported hyperacusis in chronic tinnitus with a specific focus on fear and pain related hyperacusis.

However, the multiple dimensions of hyperacusis should be considered for diagnosis and treatment in both scientific and clinical contexts.
