A Dutch study carried out recently aims to assess the effectiveness of stepped-care cognitive behaviour therapy and, compare it with the usual management in patients with varying tinnitus severity.
Tinnitus is one of the most disturbing and debilitating hearing-related problems. Here the patient perceives a distressing sound internally, even in the absence of an external source.
AdvertisementIt has been estimated that up to 21% of adults are likely to develop the condition during their lifetime. Although not easily identified, tinnitus is characterized by cognitive impairment which can be very debilitating and even affect everyday life. The condition can be very bothersome for the patients and for their family members too. There are no cures or standardized treatments for tinnitus and this makes its management even more lengthy and frustrating.
There are two main methods of treatment for tinnitus. First, sound-based therapies, such as tinnitus retraining therapy, are used to mask tinnitus. This is meant to reduce the annoyance the patient experiences from tinnitus. This therapy is usually carried out in combination with structured counseling sessions. The second main approach is cognitive behaviour therapy (CBT), which is a form of psychotherapy aimed at modifying the patient's way of thinking and dealing with a particular condition.
It is well known that CBT can reduce patient's distress and enhance the quality of life. However, it has yet not been tested if the intensity of cognitive behaviour therapy could vary depending on the severity of tinnitus.
The present study was based on the belief that treatment must be provided depending on the needs of the patients with varying severity of tinnitus. A new multidisciplinary protocol for tinnitus treatment was proposed involving a stepped-care cognitive behaviour therapy combined with certain aspects of tinnitus retraining therapy.
A clinical trial was undertaken at the Adelante Department of Audiology and Communication (Hoensbroek, Netherlands).
Dutch speakers (aged >18 years) who had tinnitus and who were previously untreated were selected for the study. It was essential that these subjects had no other health issues before participating in the study.
Patients were randomly allocated in a 1:1 ratio by the use of a computer-generated allocation sequence. Depending on their tinnitis severity, they were stratified into four layers and each of these strata were grouped in block sizes of four to be treated either with a specialized care (comprising of cognitive behaviour therapy with sound-focused tinnitus retraining therapy) or the usual care.
Patients and those investigating the outcome were masked to treatment assignment. Primary outcomes that were evaluated include health-related quality of life, tinnitus severity, and tinnitus impairment. These parameters were assessed before treatment began and at 3 months, 8 months, and 12 months after treatment was initiated.
The method of using a combination of theoretical models and treatment approaches, as was done in this study, was a new one for treating tinnitis patients. Treating tinnitus with retraining therapy-based approaches is only moderately effective. Cognitive behaviour therapy seems the most promising approach in treating tinnitis and in reducing tinnitis- related patient distress.
Stepped up management, combining the components of retraining therapy within the framework of cognitive behavior therapy while taking into account the severity of the complaint, appears to be the most effective in managing tinnitus.
