Degrees of tinnitus distress were explored in a sample of 216 patients who completed audiological measures and were assessed in a structured interview conducted by a clinical psychologist. The Klockhoff and Lindblom grading system was used and its inter-rater reliability assessed in a subsample showing a high degree of correspondence. Results from the(More)
OBJECTIVE The aim of this study was to investigate if cognitive behavior therapy (CBT) provided via the Internet results in significant decreases of distress in individuals with tinnitus. METHODS Participants were recruited through Web pages and newspaper articles and thereafter randomly allocated to a CBT self-help manual in six modules or to a(More)
Meta-analysis is a technique of combining results from different trials in order to obtain estimates of effects across studies. Meta-analysis has, as yet, rarely been used in audiological research. The aim of this paper was to conduct a meta-analysis on psychological treatment of tinnitus. The outcomes of 18 studies, including a total of 24 samples and up(More)
In a nation-wide investigation, covering all the hearing centres in Sweden, a study was made of adaptation processes, subjective discomfort from tinnitus, subjective loudness of tinnitus and psychological complaints in 3372 subjects by means of a questionnaire. The most important predictors of discomfort from and adaptation to tinnitus were found to be the(More)
OBJECTIVE To investigate the long-term outcome of patients with tinnitus, the long-term effects of cognitive behavioral therapy, and what properties of tinnitus predict distress at follow-up. DESIGN A longitudinal follow-up of a consecutive sample of patients with tinnitus initially seen by a clinical psychologist. SETTING Department of Audiology,(More)
The aim of this study was to investigate cognitive interference caused by tinnitus by means of a modified version of the Stroop color-word test. In a mixed-design study, the performances of tinnitus patients (n = 23) and healthy controls with normal hearing (n = 23) were compared on three versions of the Stroop test: the original version, a modified version(More)
Brain imaging of tinnitus has suggested central correlates of tinnitus perception. This study presents positron emission tomographic (PET) measurements of regional cerebral blood flow (rCBF) in a female tinnitus patient with bilateral left dominant tinnitus. Lidocaine infusion (75 mg during 5 min (0.2 mg/kg/min)) resulted in a 75% reduction of tinnitus and(More)
Forty hearing-impaired subjects were exposed to three stressful communication situations in a laboratory setting. The communication patterns used and the extent to which the subjects succeeded in coping with the situations were studied. Measures, such as the life orientation test measuring dispositional style, a hearing questionnaire measuring the ability(More)
In an audiometric study on 38,294 conscripts, noise-induced high-frequency hearing deterioration during basic training (mean 245 days) was studied. On reporting for training, 29% were found to have hearing defects, predominantly in the high-frequency area. After training, high-frequency deterioration, predominantly unilateral or asymmetrical, was found in(More)
Twenty-four patients with moderately severe (grade 2) to severe (grade 3) subjective tinnitus participated in an experimental group study. The patients were randomly assigned to a treatment group and a waiting-list control group. Treatment was given with a coping technique and comprised 10 one-hour sessions. Following a corresponding period without(More)
