Tinnitus: differential effects of therapy in a single case

Background: People with troublesome tinnitus often experience emotional distress. Therefore a psychometrically sound instrument which can evaluate levels of distress and change over time is necessary to understand this experience. Clinical Outcomes in Routine Evaluation (CORE-OM) is a measure of emotional distress which has been widely used in mental health research. Although originally designed as a 4-factor questionnaire, factor analyses have not supported this structure and a number of alternative factor structures have been proposed in different samples. The aims of this study were to test the factor structure of the CORE-OM using a large representative tinnitus sample and to use it to investigate levels of emotional distress amongst people with a range of tinnitus experience. Methods: The CORE-OM was completed by 342 people experiencing tinnitus who self-rated their tinnitus on a 5-point scale from 'not a problem' to 'a very big problem'. Confirmatory factor analysis was used to test all ten factor models which have been previously derived across a range of population samples. Model fit was assessed using fit criterion and theoretical considerations. Mean scores on the full questionnaire and its subscales were compared between tinnitus problem categories using one-way ANOVA. Results: The best fitting model included 33 of the 34 original items and was divided into three factors: negatively worded items, positively worded items and risk. The full questionnaire and each factor were found to have good internal consistency and factor loadings were high. There was a statistically significant difference in total CORE-OM scores across the five tinnitus problem categories. However there was no significant difference between those who rated their tinnitus 'not a problem', and 'a small problem' or 'a moderate problem.' Conclusion: This study found a 3-factor structure for the CORE-OM to be a good fit for a tinnitus population. It also found evidence of a relationship between emotional distress as measured by CORE-OM and perception of tinnitus as a problem. Its use in tinnitus clinics is to be recommended, particularly when emotional distress is a target of therapy.

Objectives-Questionnaires are essential for measuring tinnitus severity and intervention-related change but there is no standard instrument used routinely in research settings. Most tinnitus questionnaires are optimised for measuring severity but not change. However, the Tinnitus Functional Index (TFI) claims to be optimised for both. It has not however been fully validated for research purposes. Here we evaluate the relevant psychometric properties of the TFI, specifically the questionnaire factor structure, reproducibility, validity and responsiveness guided by quality criteria for the measurement properties of health-related questionnaires. Methods-The study involved a retrospective analysis of data collected for 294 members of the general public who participated in a randomised controlled trial of a novel tinnitus device (ClinicalTrials.gov Identifier: NCT01541969). Participants completed up to eight commonly used assessment questionnaires including the TFI, Tinnitus Handicap Inventory (THI), Tinnitus Handicap Questionnaire (THQ), a Visual Analogue Scale of loudness (VAS-Loudness), Percentage Annoyance question, the Beck's Depression Inventory (BDI), Beck's Anxiety Inventory (BAI), and the World Health Organisation Quality of Life-Bref (WHOQOL-BREF). A series of analyses assessed the study objectives. Forty four participants completed the TFI at a second visit (within 7-21 days and before receiving any intervention) providing data for reproducibility assessments. Results-The 8-factor structure was not fully confirmed for this general (non-clinical) population. Whilst it was acceptable standalone subscale, the 'auditory' factor showed poor loading with the higher order factor 'functional impact of tinnitus'. Reproducibility assessments for the overall TFI indicate high internal consistency (α = 0.80) and extremely high reliability (ICC: 0.91), whilst agreement was borderline acceptable (93%). Construct validity was demonstrated by high correlations between scores on the TFI and THI (r = 0.82

Dimensions of psychological complaints due to chronic and disabling tinnitus were investigated by means of the Tinnitus Questionnaire (TQ), administered to a sample of 138 tinnitus sufferers who had been admitted to a psychosomatic hospital. Factor analysis revealed that tinnitus-related patterns of emotional and cognitive distress, intrusiveness, auditory perceptual difficulties, sleep disturbances, and somatic complaints can be differentiated. Cognitive distortions and inappropriate attitudes towards the tinnitus and it's personal consequences were found to be highly intercorrelated forming a subgroup within a broader and more general distress factor. The stability of the factor solution obtained was examined by systematically varying the number of factors to be extracted. Based on the results of this method, scales are proposed for the questionnaire which can be used in clinical and scientific work to specifically assess major areas of tinnitus-related distress and their degree of severity. Implications for a further evaluation of the instrument are discussed.

The aim of this study was to determine the validity of the Italian translation of the Tinnitus Handicap Inventory (THI) by Newman et al. in order to make this self-report measure of perceived tinnitus handicap available both for clinical and research purposes in our country and to contribute to its cross-cultural validation as a self-report measure of perceived severity of tinnitus. The Italian translation of the Tinnitus Handicap Inventory (THI) was administered to 100 outpatients suffering from chronic tinnitus, aged between 20 and 82 years, who attended the audiological tertiary centres of the University Hospital of Modena and the Regional Hospital of Treviso. No segregation of cases was made on audiometric results; patients suffering from vertigo and neurological diseases were excluded. Pyschoacoustic characteristics of tinnitus (loudness and pitch) were determined and all patients also completed the MOS 36-Item Short Form Health Survey to assess self-perceived quality of life a...

This study tested a theoretical model of tinnitus-related distress and of general distress that involved acceptance of tinnitus symptoms and emotional intelligence as factors that may protect against such distress. One hundred and sixty-two tinnitus sufferers from throughout Australia completed measures of acceptance of tinnitus symptoms, emotional intelligence, tinnitus-related distress, and general distress. As hypothesized, greater acceptance of tinnitus symptoms was associated with less tinnitusrelated distress. Emotional intelligence was not associated with tinnitus distress. Greater acceptance and less tinnitus distress were both associated with less general distress, and the association between acceptance and general distress was mediated by tinnitus-related distress. The findings, which provide partial support for the tested model, may have implications for efforts to assist distressed tinnitus sufferers.

The objective of this study was to determine the reliability and validity of a Danish translation of the Tinnitus Handicap Inventory (THI), a self-report measure of perceived tinnitus handicap. The Danish version of the THI was administered to 50 patients reporting tinnitus as their primary complaint or secondary to hearing loss. Construct validity was assessed using tinnitus symptom rating scales, the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), the Tinnitus Coping Style Questionnaire (TCSQ), the Eysenck Personality Questionnaire (EPQ), and perceived tinnitus loudness and pitch. The Danish translation of the THI and its subscales showed good internal consistency reliabilities (a = 0.93 to a = 0.74) comparable to those of the original version. High to moderate correlations were observed between THI and psychological distress, tinnitus symptom ratings, neuroticism and maladaptive tinnitus coping. A confirmatory factor analysis failed to validate the three subscales of THI, and high intercorrelations found between the subscales question whether they represent three distinct factors. The results suggest that the Danish THI-Total scale may be a reliable and valid measure of general tinnitus related distress that can be used in a clinical setting to quantify the impact of tinnitus on daily living.

Introduction:Tinnitus can have a significant effect on an individual’s quality of life, and is very difficult quantify. One of the most popular questionnaires used in this area is the Tinnitus Handicap Inventory (THI). The aim of this study was to determine the reliability and validity of a Persian translation of the Tinnitus Handicap Inventory (THI-P). Materials and Methods: This prospective clinical study was performed in the Otolaryngology Department of Guilan University of Medical Sciences, Iran. A total of 102 patients aged 23–80 years with tinnitus completed the (THI-P). The patients were instructed to complete the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI). Audiometry was performed. Eight-five patients were asked to complete the THI-P for a second time 7–10 days after the initial interview. We assessed test–retest reliability and internal reliability of the THI-P. Validity was assessed by analyzing the THI-P of patients according to their age, tinnitus duration and psychological distress (BDI and STAI). A factor analysis was computed to verify if three subscales (functional, emotional, and catastrophic) represented three distinct variables. Results: Test–retest correlation coefficient scores were highly significant. The THI-P and its subscales showed good internal consistency reliability (α = 0.80 to 0.96). High-to-moderate correlations were observed between THI-P and psychological distress and tinnitus symptom ratings. A confirmatory factor analysis failed to validate the three subscales of THI, and high intercorrelations found between the subscales question whether they represent three distinct factors. Conclusion: The results suggest that the THI-P is a reliable and valid tool which can be used in a clinical setting to quantify the impact of tinnitus on the quality of life of Iranian patients.

The Tinnitus Functional Index (TFI) has been optimised as a diagnostic tool for quantifying the functional impact of tinnitus in US veteran and civilian groups. However, the TFI has not been fully evaluated for use in other English-speaking clinical populations despite its increasingly popular uptake. Here, a prospective multi-site longitudinal validation study was conducted to evaluate psychometric properties relevant to the UK clinical population. Guided by quality criteria for the measurement properties of health-related questionnaires, we specifically evaluated three diagnostic properties relating to the degree to which the TFI (i) covers the eight dimensions proposed to be important for diagnosis, (ii) reliably distinguishes individual differences in severity of tinnitus, and (iii) reliably measures the functional impact of tinnitus. We also examine whether clinically meaningful interpretations of the scores can be produced for the UK population. Twelve National Health Service ...

The study was carried out to determine the impact of some co-morbid otological symptoms and demographic factors on the emotional distress and cognitive functioning in patients with tinnitus. One hundred consecutive patients, complaining of constant idiopathic tinnitus, were enrolled into the study. Four tests were administered: Beck Depression Inventory, Hospital Anxiety Depression Scale (HADS, A-anxiety, D-depression), Mini-Mental State Examination (MMSE) and Trail Making Test (TMT). A multivariate stepwise linear regression analysis was performed to estimate the relationship between the results of each of the tests and following co-morbid factors: age, sex, tinnitus duration, tinnitus laterality, hearing status (normal hearing, unilateral hearing loss and bilateral hearing loss) and vertigo/dizziness. It was found that the scores of MMSE and TMT were negatively correlated with age and with hearing status and the scores of HADS-A were slightly correlated with sex. In regression analysis, in HADS-A, sex and to a lesser extent tinnitus duration, in MMSE and TMT age and to a lesser extent tinnitus laterality were the variables that were comprised in the final model. Demographic factors had contributed more than overlapping otological symptoms to the psychological outcome in tinnitus patients.

The conceptual International Classification of Functioning Disability and Health (ICF) framework which defines functioning and disability in a new broader, universal perspective has been used to study tinnitus. 22 adults between 30-60 years with tinnitus were included in the study. Routine audiological assessment was followed by administering THI, HHIA and HADS on the subjects. To enhance the context of response, concept mapping of the scales to domains under BF and AP of ICF was done prior to administration. Kappa statistic showed moderate agreement for THI (k= 0.519, p=0.005), fair agreement for HHIA (k= 0.519, p=0.04) and moderate to substantial agreement for HADS (k= 0.595, p=0.02) items. Comparison of performance scores between Body Functions(BF) and Activities and Participation (AP) using Mann Whitney test showed statistically significant high mean score of 32.27 for BF compared to12.73 for AP (U = 27, p <0.05). Findings indicated psychological issues related to tinnitus were more dominant compared to functional issues. Kruskal-Wallis test conducted to study the comparisons of AP and BF scores across the THI severity grades showed no significant difference ( 2 =3.15, p=0.20) of AP scores, whereas BF scores varied significantly across THI severity levels ( 2 =6.28, p=0.03). This suggested an equal impact of tinnitus on Activity Limitation and Participation Restriction (AL/PR) of subjects irrespective of its perceived severity.
