Tinnitus distress can be reduced by means of cognitive-behavior therapy (CBT). To compensate for the shortage of CBT therapists, we aimed, in this study, to investigate the effects of a CBT-based self-help book guided by brief telephone support.
                Seventy-two patients were randomized either to a self-help book and seven weekly phone calls or to a wait-list control condition, later on receiving the self-help book with less therapist support. The dropout rate was 7%. Follow-up data 1 year after completion of treatment were also collected (12% dropout). The Tinnitus Reaction Questionnaire (TRQ) was the main outcome measure, complemented with daily ratings of tinnitus and measures of insomnia, anxiety, and depression.
                On the TRQ, significant reductions were found in the treatment group both immediately following treatment and at 1-year follow-up. In the treatment group, 32% reached the criteria for clinical significance (at least 50% reduction of the TRQ) compared to 5% in the wait-list group. Directly after treatment, two out of five measures showed significant differences in favor of the treatment with more therapist support compared with the group who, after their waiting period, received little therapist support. The self-help treatment was estimated to be 2.6 (seven phone calls) and 4.8 (one phone call) times as cost-effective as regular CBT group treatment.
                Guided self-help can serve as an alternative way to administer CBT for tinnitus. Preliminary results cast some doubts on the importance of weekly therapist contact. The effect size was somewhat smaller than for regular CBT, but on the other hand, the self-help seems far more cost-effective. Future studies should compare treatment modalities directly and explore cost-effectiveness more thoroughly. Sixty subjects with chronic tinnitus were randomly allocated to one of three experimental conditions: (1) cognitive coping skills training (attention diversion, imagery training and thought management skills) combined with education. (2) education-only, or (3) waiting-list control. The two treatment groups improved significantly more than the waiting-list control on measures of frequency of use of coping strategies, benefits derived from the use of coping strategies, irrational beliefs and knowledge about tinnitus. Subjects who received the combined cognitive/education intervention demonstrated significantly greater reductions in distress and handicaps associated with tinnitus, and engagement in dysfunctional cognitions, than the subjects who received education alone. No significant effects were obtained on measures of depression, locus of control, or on daily ratings of subjective loudness, noticeability or bothersomeness of the tinnitus. At the 12-month follow-up, the differential treatment effects had dissipated. Although the treatment resulted in statistically significant effects, the size of the clinical effects is rather modest. Implications for the further development of treatment techniques are discussed. To determine whether the antidepressant, nortriptyline, is effective for treatment of depression, tinnitus-related disability, and tinnitus symptoms in patients with severe chronic tinnitus.
                A 12-week, double-blind, randomized controlled trial.
                A university otolaryngology clinic.
                Ninety-two subjects with severe chronic tinnitus: 38 with current major depression and 54 with depressive symptoms and significant tinnitus-related disability.
                Nortriptyline (maintained at 50 to 150 mg/mL for 6 weeks) or placebo.
                Hamilton Depression Rating Scale, Tinnitus Disability Measures, and Audiometric Measures.
                Nortriptyline was superior to placebo by multivariate analysis of covariance for depression (10.6 vs 14.3 final Hamilton Depression score), for tinnitus-related disability (1.8 vs 2.4 final MPI Tinnitus Interference), and tinnitus loudness (13.6 vs 20.0 dB final loudness match [in worst ear at tinnitus frequency]). When major depression and depressive symptoms groups were considered separately, nortriptyline was superior to placebo on these same measures but differences did not achieve statistical significance.
                The antidepressant nortriptyline decreases depression, functional disability, and tinnitus loudness associated with severe chronic tinnitus. What appears to be irreversible disability of otologic origin may, in part, be reversible disability of psychiatric origin. The pathophysiologic mechanisms of idiopathic tinnitus remain unclear. Low frequency rTMS applied over the auditory cortex has been proposed as a new and causally oriented treatment approach for pathological conditions with abnormal, increased cortical activity including tinnitus with increased activity in the auditory cortex. However available studies are characterized by a positive reports on the therapeutic effects of repetitive transcranial magnetic stimulation (rTMS) for treatment of tinnitus, there are few details about the duration of specific treatment effects.
                The design of the study was randomized, prospective, placebo-controlled. Right-handed patients were treated with either real or sham 1 Hz frequency rTMS over a period of two weeks. Fifty-two patients with chronic, treatment resistant tinnitus and stable medication were enrolled in the study after giving written informed consent and forty-two patients completed the study and were included in data analysis.
                The ability to reduce the symptoms of tinnitus appeared in both randomized groups immediately after the 1 Hz rTMS and sham stimulation phase. There was a significant reduction in both groups of the tinnitus total score on the Tinnitus Handicap Inventory (THI) (real rTMS p=0.005; sham rTMS p=0.049) and Tinnitus Questionnaire (TQ) total score (real rTMS p=0.003; sham rTMS p=0.049). On the THI evaluation scale, in the real rTMS a mild worsening was noted during week 6 in comparison with the state attained in week 2. During the subsequent course of the study a significant reduction of the total score persisted in the case of THI (real rTMS week 14 p=0.033 and borderline week 26 p=0.058). The reduction of symptoms as evaluated using the TQ was significant compared to baseline in the real rTMS group at week 2, 6 and 14 (p=0.003; p=0.024; p=0.022). The group treated with sham stimulation reached significant reduction of symptoms only at week 2 (p=0.049). A comparison of the difference in the recorded values of the total score during follow-up in relation to baseline expressed as a percentage demonstrates the difference in the effect of rTMS and sham stimulation as evaluated by both the basic scales. Graphical analysis of mean patterns of treatment response according to stimulation type shows a similarity between treatment response patterns evaluated by reduction of the total scores using THI and TQ.
                The principal finding of this study is that real 1 Hz rTMS treatment was capable of significantly reducing the total baseline score of basic scales that measure tinnitus severity. This result is important as it proves that significant reduction of symptoms can be achieved even in a group of patients with long-term symptoms resistant to pharmacological treatment. The efficiency of two treatment modalities for subjective/idiopathic tinnitus (SIT): biofeedback (BF) and amitriptyline hydrochloride (AT) was investigated in 225 randomly selected subjects. Findings show that after 10 weeks of treatment in the BF group, 43.5% of the patients reported an improvement of tinnitus during activity. In the AT group, 27.5% of patients reported subjective improvement of tinnitus at rest although only 15.8% of the AT patients reported improvement during activity. Biofeedback during rest had a significantly better effect on tinnitus disturbance than AT. No objective diminishment of tinnitus loudness was found as a result of any of the treatment modalities. We believe that BF can help tinnitus patients especially during periods of rest and we also suggest trying tricyclic antidepressant drugs such as AT for treatment of tinnitus patients, in small doses, however, to minimize the side effects of this drug. Subjective tinnitus (ST) is one of the most common and yet most unclear of otologic symptoms.(1-4) ST can accompany any type of hearing loss including both sensorineural as well as conductive hearing loss, and may originate from any part of the auditory pathway.(1,5) Treatment of ST must be primarily directed to the basic illness diagnosed after a thorough general ear-nose-throat and neurologic evaluation.(6) Severity of ST is evaluated both objectively, by determining the pitch and intensity of the tinnitus,(7) and subjectively as described by the patient. Because of the relatively high incidence of ST and in some patients, the severe personal reaction to it, many different treatments have been suggested, but generally only small to moderate success has been achieved in reducing tinnitus and its consequences, if any at all.(8) In this study we examined the effect of two treatment modalities: amitriptyline hydro-chloride and biofeedback. Many tinnitus sufferers believe that their tinnitus has an organic basis and thus seek medical rather than psychological treatments. Tinnitus has been found to be associated with negative appraisal, dysfunctional attention shift, and heightened psychophysiological arousal, so cognitive-behavioral interventions and biofeedback are commonly suggested as treatments. This study developed and investigated the efficacy of a biofeedback-based cognitive-behavioral treatment for tinnitus. In total, 130 tinnitus patients were randomly assigned to an intervention or a wait-list control group. Treatment consisted of 12 sessions of a biofeedback-based behavioral intervention over a 3-month period. Patients in the wait-list group participated in the treatment after the intervention group had completed the treatment. Results showed clear improvements regarding tinnitus annoyance, diary ratings of loudness, and feelings of controllability. Furthermore, changes in coping cognitions as well as changes in depressive symptoms were found. Improvements were maintained over a 6-month follow-up period in which medium-to-large effect sizes were observed. The treatment developed and investigated in this study is well accepted and leads to clear and stable improvements. Through demonstration of psychophysiological interrelationships, the treatment enables patients to change their somatic illness perceptions to a more psychosomatic point of view. In 20 patients diagnosed with Menière's disease, transcutaneous nerve stimulation (TNS) and applied relaxation (AR) were used as a treatment aimed at reducing tinnitus and dizziness and increasing hearing ability. The main aim of the study was to examine whether TNS could be regarded as a more beneficial treatment regimen than AR. An experimental between-group cross-over design was used. The results from the experimental phase (group comparisons) showed a significantly increased ability to hear for the TNS group when measured on visual analogue scales. During the same period, the AR-group showed a significant hearing improvement for the ear not primarily affected by Menière's disease as measured with pure tone audiometry. The vestibular tests did not reveal any significant changes either after TNS or AR intervention. Tinnitus matching showed changes of pitch and loudness before and after both TNS and AR intervention. However, no statistically significant changes between treatment regimes were found on these measures. The results from this study did not show TNS to be superior to AR in reducing tinnitus, dizziness or increasing hearing ability. Sixty-five subjects were reviewed 12 months after tinnitus management training, which had been comprised variously of information, relaxation training and a therapeutic noise strategy. Seventy-four per cent of subjects reported increased habituation to tinnitus (n = 48), 65% reported reduced tinnitus annoyance (n = 42), and 52% reported an increased ability to cope with tinnitus (n = 34). Twenty-five per cent of subjects reported deterioration in coping ability (n = 16), 23% reported reduced habituation to tinnitus (n = 15) and 8% reported increased tinnitus-related annoyance (n = 5). None of the management strategies were found to be significantly more effective than others in facilitating improved coping or habituation to tinnitus. Subjects who reported reduced coping and habituation to tinnitus experienced greater levels of general life stress than subjects who reported increased habituation and coping ability. The use of relaxation therapies as applied in this study did not appear to influence the level of tinnitus distress or the level of life stress. Thirty-seven per cent of subjects given long-term low-level white noise (LTWN) stimulation reported benefit. However, LTWN stimulation did not significantly alter tinnitus awareness or the minimum masking level (MML) of tinnitus. Long-term low-level white noise stimulation appeared to influence cognitive reaction to tinnitus rather than its physical perception. Subjects who initially had low ability to cope with tinnitus and preferred a more active coping style reported significantly greater benefit from LTWN stimulation than subjects whose primary approach to coping was to regulate the emotional impact of tinnitus. There has been little research examining group cognitive-behavioral therapy (CBT) for schizophrenia, especially compared to an active control treatment. The purpose of this study was to investigate the effectiveness of group CBT for auditory hallucinations compared to an enhanced supportive therapy (ST). Sixty five participants with schizophrenia spectrum disorders and persistent hallucinations were randomly assigned to group CBT or enhanced group ST. Primary outcomes focused on beliefs about voices and global auditory hallucinations severity. Secondary outcomes included psychotic symptoms, self-esteem, social functioning, insight, depression, and hospitalization. Controlling for baseline levels, these outcomes were evaluated across post-treatment, 3 month and 12 month follow-ups. Participants who received enhanced ST were less likely to both resist voices and to rate them as less malevolent through 12-month follow-up relative to participants who received CBT. Group CBT was associated with lower general and total symptom scores on the PANSS through 12-month-followup relative to participants who received enhanced ST. Outcomes improved through 12-month follow-up in both therapy groups, with enhanced ST having more specific impact on auditory hallucinations, and CBT impacting general psychotic symptoms.
In six studies we found no evidence of a significant difference in the subjective loudness of tinnitus.
However, we found a significant improvement in depression score (in six studies) and quality of life (decrease of global tinnitus severity) in another five studies, suggesting that CBT has a positive effect on the management of tinnitus.
