This work evaluates an enhanced tinnitus retraining therapy (TRT) for patients with chronic tinnitus based on different group therapeutic interventions in a day hospital setting. Therapy for chronic tinnitus is intended to improve the way patients cope with tinnitus by learning how to reduce tinnitus-induced impairments. Short-term and long-term changes in stress variables and tinnitus-related distress were investigated using 3 psychometric instruments. Patients received 7 consecutive days of a multidisciplinary therapy at the Charité University Hospital in Berlin. The data were assessed before and after therapy, either immediately or after 3, 6 or 12 months. As a control, we used scores of tinnitus patients from the waiting list, and compared these to the scores of the therapy group 3 months after the end of treatment. The main factors of the modified TRT were Jacobson’s progressive muscle relaxation, physiotherapy, education via lectures and training of selective attention, as well as changes of appraisal, mental attitude and behavior towards tinnitus. The therapy resulted in a significant reduction in both short-term and long-term tinnitus-related distress and psychometric stress variables, with the latter being more reduced in patients with higher initial scores. Moreover, our study revealed differences in psychometric parameters concerning duration of tinnitus, age and gender, which may explain the different outcomes of therapy. The outpatient setting enables the patients to test, practice and transfer strategies into their everyday life.
The authors found gender differences regarding tinnitus-related distress in patients with chronic tinnitus; however, these differences depended on age and in part on duration of tinnitus. Addressing these differences could result in improved, tailored therapy approaches. For instance, applying physical exercise and relaxation techniques could be of special help for older women to reduce their somatic complaints and sleep disturbances. Similarly, cognitive behavioral therapy could reduce their cognitive distress. Therapy for younger patients should in particular include stress management.
In the present study, we have detected a high rate (almost half of the cases) of psychological disorders occurring in patients with chronic tinnitus. The patients diagnosed with psychological disorders were predominantly affected by affective and anxiety disorders. Psychological disorders were associated with severity of tinnitus distress. Our findings imply a need for routine comprehensive screening of mental disorders in patients with chronic tinnitus.
Besides collecting medical and social history, special psychometric instruments should be used for the diagnosis of tinnitus patients. Based on relative high frequency of psychological comorbidity, we recommend interdisciplinary cooperation between otorhinolaryngologists and other specialists (psychosomatic medicine, psychology or psychiatry) during the treatment of tinnitus patients, especially when high degree of tinnitus annoyance is involved.
