Psychophysiological Treatment of Chronic Tinnitus

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.

Additionally the psychophysiological reactivity under different stress-conditions is measured before and after intervention or waiting. Therefore the activity of the muscles of head and shoulders (EMG) as well as the skin temperature and skin conductance are measured. It is hypothesized that patients with stronger psychophysiological reactivity benefit more from an psychophysiological intervention.

Further aims of the study are 1) to compare the muscle activity of the tinnitus-patients with those from healthy controls, because till now no study investigated if tinnitus-patients effectively present higher muscle activity in head and shoulders than healthy people and 2) to evaluate the influence of the subjective illness perceptions on the intervention-outcome, because it is hypothesized that patients with more somatic illness perceptions benefit more from a psychophysiological intervention than patients with rather psychological illness perceptions.
