The study aims to develop and to evaluate a psychophysiological intervention for distressing chronic tinnitus. Therefore 100 people suffering from chronic tinnitus are randomly assigned to either an intervention-group, receiving 12 sessions of a psychophysiological oriented intervention, or to a waiting-list-group, who are waiting for a comparable time period. Afterwards, patients of the waiting-list-group also receive intervention. The effects of the intervention on severity, distress and perceived loudness of the tinnitus as well as on other psychological variables like depression or self-efficacy are evaluated through comparing the results of the intervention group with those of the waiting-list-group.
