Introduction: Tinnitus is often associated with disturbed sleep, but there are also patients without sleep problems. The mechanisms for developing insomnia or not in tinnitus patients are still unknown. The aim of the present study was to extract possible tinnitus specific factors that increase the risk of developing insomnia based on the analysis of a large patient cohort suffering from chronic tinnitus. Method: 173 patients presenting at the multidisciplinary tinnitus center of a University Hospital completed a questionnaire measuring specific psychological symptoms of insomnia (RIS) and a tinnitus questionnaire (TQ). The scores of all ten RIS items were compared between tinnitus patients and 94 healthy individuals by separate ANOVAs in order to specify the extent of insomnia specific symptoms in the tinnitus group. In a second step a multiple linear regression analysis was performed in the tinnitus sample with subscales of the TQ (excluding the TQsleep scale), age and duration of tinnitus as independent variables and the RIS score as the dependent variables. Results: Tinnitus patients differed from healthy controls not only in impaired sleep quality but also in insomnia specific concerns and anxiety. Tinnitus related emotional and cognitive distress and somatic complaints correlated with severity of insomnia, whereas no association of age or duration of tinnitus with severity of insomnia was found. Conclusion: Our results suggest that chronic tinnitus patients have more sleeping difficulties and associated worries about sleep or negative emotions in contrast to healthy controls.
