Validation of the Chronic Tinnitus Acceptance Questionnaire (CTAQ-I): the Italian version
Tinnitus is a widespread symptom that is chronically experienced by approximately 10% of the adult population. While the vast majority of individuals do not feel impaired by their ear noise, about 0.5-3% of the adult population develops severe distress and feels impaired in everyday life. The severity of the distress experienced can only partially be explained by the characteristics of the ear noise itself (e.g. objective tinnitus loudness or duration). Psychological variables such as tinnitus acceptance are being increasingly investigated by tinnitus research. The aim of this study was to analyse the psychometric quality of the Italian version of the “Chronic Tinnitus Acceptance Questionnaire” (CTAQ-I). The CTAQ-I is an adaption of the Italian “Chronic Pain Acceptance Questionnaire (CPAQ)” and altered for the study of tinnitus acceptance. This cross-sectional multicentre questionnaire study included 141 outpatients with chronic tinnitus. Sociodemographic and clinical data were assessed with the Tinnitus Sample Case History (TSCH), tinnitus acceptance with the Italian “Chronic Tinnitus Acceptance Questionnaire” (CTAQ-I), tinnitus distress with the Tinnitus Handicap Inventory (THI) and the Tinnitus Questionnaire Short Form (TQ 12-I). Furthermore, we assessed the patient’s general psychological distress (Brief Symptom Inventory - BSI) and Health Related Quality of Life (SF-36). Psychometric and factorial evaluation of the CTAQ-I were carried out. To investigate the influence of sociodemographic and numerous clinical variables on tinnitus acceptance we calculated correlation coefficients, analysis of variance and independent sample-t-tests. The factor analysis revealed a two-factor solution (“activity engagement” and “tinnitus willingness”), accounting for 41.1% of the variance. Good internal consistency for the total score (α = 0.84) and both factors (α = 0.80-0.88) was found. Moderate negative correlations with tinnitus distress indicated good validity. Tinnitus acceptance was further correlated with lower psychological distress and subjective tinnitus loudness, as well as increased emotional well-being. Tinnitus acceptance is considered to be an important source of therapeutic change in behavioural-based treatments as well as in professional counselling for tinnitus. Our study shows that the CTAQ-I is a reliable and valid instrument to measure the acceptance of patients suffering from chronic tinnitus.
Tinnitus is defined as the perception of sound in the absence of a corresponding auditory source. Epidemiological studies report a prevalence of 10-16% for chronic tinnitus in the adult population, which increases with age 1 2. While the vast majority of individuals are unaffected by tinnitus, 0.5-3% of the adult population report impairing tinnitus-associated symptoms of disturbed sleep and decreased cognitive functions, irritability, disruption of everyday activities as well as psychological problems such as anxiety and depressive symptoms 3 4. Distressing tinnitus is often associated with audiological dysfunctions, noise sensitivity and impaired quality of life of patients and in many cases their relatives as well 5-7.
The subjectively experienced strain due to tinnitus can only partially be explained by psychoacoustic parameters such as objective tinnitus loudness or duration 8. A large body of literature suggests that tinnitus related cognitions (e.g. catastrophic thinking), emotions (e.g. anxiety and depression) and personality traits as well as coping strategies play an important role in tinnitus perception and distress 9-12.
Since there is no specific pharmacological treatment available to cure chronic tinnitus 13, at present therapeutic strategies support the process of coping with tinnitus, building stress management and treating comorbid symptoms. Cognitive behavioural interventions are, in addition to multimodal therapies, the most widely used treatment strategies 13. Independent meta-analyses and systematic reviews revealed convincing evidence for the efficacy of cognitive behavioural therapies to reduce tinnitus-related distress 14 15.
In the recent development of cognitive-behavioral treatments, acceptance- and mindfulness-based approaches, such as the “Acceptance and Commitment Therapy” or the “Mindfulness-Based Cognitive Therapy”, have been integrated in the treatment of tinnitus 16-18. These approaches are considered particularly relevant when dealing with a chronic problem, such as chronic tinnitus. There are a growing number of experiential, correlational and outcome studies showing that tinnitus related acceptance is related to better functioning and well-being 18-22.
The word “acceptance” takes its roots from the Latin word “accipere” which means “admit, let in, hear, learn”. Psychological acceptance is also described as a mindful and non-evaluative approach to internal experiences such as emotions, physical sensations or thoughts. Acceptance has been further described as the openness to experience thoughts and emotions as they are, while refraining from attempting to direct and actively change these situations, feelings, and thoughts. Psychological acceptance does not equate to an attitude of resignation or “giving up”, but is characterised by an active shaping of the situation in the presence of tinnitus. Currently, it is not entirely clear which specific individual coping strategies are useful or maladaptive for long-term adaptation to chronic tinnitus. A useful model for the understanding of the tinnitus adaptation process and the value of acceptance is provided by the “dual-process model of coping” by Brandtstädter and Renner 23. It distinguishes between two complementary coping strategies: accommodative and assimilative coping. The assimilative coping mode is characterised by active attempts to change or control a stressful situation, like a chronic burden or health impairment. This persistent way of pursuing one’s goal can include activities such as acquiring relevant knowledge and skills, or using compensatory means (e.g. using external support sources such as hearing aids and sound generators to solve the problem). When a problem remains unresolved and blocks life goals, the level of stress usually increases and a transition from assimilative to accommodative coping may be required. Accommodative coping is the flexible adjustment of individual goals and preferences to situational constraints or limitations. This can involve the devaluation or reevaluation of a particular goal (e.g. the elimination of tinnitus), as well as the consideration of alternative feasible goals. The acceptance of adverse consequences and uncontrollability of an insoluble problem is often considered as a key process in accommodative coping.
For many patients, the word acceptance has a bad overtone because it means to give up the expectation of getting rid of their tinnitus. Patients often maintain a high level of activity to avoid “giving up” or passive suffering from tinnitus or are constantly struggling against it. This may also include a constant search for new treatments and at considerable personal and financial costs. These constant strong assimilative efforts toward a blocked target (i.e. the extinction of tinnitus) can lead to the exhaustion of one’s own action resources and increased psychological distress.
On a theoretical level, acceptance is closely related to its opposite psychological process - experiential avoidance (EA). EA is defined as the avoidance of internal sensations, thoughts etc. Avoidance behaviour may intensify negative thoughts 24 and is linked to more distressing tinnitus as well as increased anxiety and tinnitus-related distress. Patients suffering from chronic tinnitus often avoid specific situations, including silence as well as certain sounds that are perceived as annoying 25. Some patients remove themselves from social relations to offer protect from noise pollution 26 or to avoid high (sometimes potentially harmful) noise levels 27. Another avoidance tactic used is to mask the tinnitus by persistently distracting oneself using background sounds like radio or TV-sets. Although EA is associated with short-term relief, in the long run it strongly impairs the patients’ quality of life. While trying to protect oneself from a disabling tinnitus by avoiding its perception and associated emotions and thoughts, this may paradoxically lead to increased anxiety and tinnitus-related distress 28.
Acceptance refers to a process by which the tinnitus and associated thoughts and feelings lose their functional influence on overt behaviour, since the target of control is changed from uncontrollable factors (i.e. the tinnitus itself) to more controllable factors (i.e. changing behaviour to increase daily function despite tinnitus).
In order to evaluate the efficacy of acceptance-orientated treatment, specific and validated instruments to measure acceptance are necessary. In the treatment of chronic pain, acceptance-oriented instruments such as the “Chronic Pain Acceptance Questionnaire” (CPAQ) have already been developed and validated. Due to various similarities often described between chronic pain and chronic tinnitus – both groups suffer from intractable sensory symptoms and demonstrate problems with aspects of focus/attention, perceived lack of control over symptoms, catastrophic thinking and maladaptive coping strategie – the CPAQ has been adapted for tinnitus in English (Moreland 2009, unpublished thesis) as well as German 29. To our knowledge no tinnitus acceptance questionnaire has been developed in Italian thus far.
Therefore, the aim of the present study was to evaluate the psychometric properties of the Italian CTAQ-I and to investigate its relationship to tinnitus distress, well-being and psychological distress.
Materials and methods
Sample and setting
The sample of this cross-sectional multicentre study consisted of 150 outpatients which were included from the following healthcare institutions: Tinnitus Centre, European Hospital (Rome), the Department of Otorhinolaryngology, “Guglielmo da Saliceto” Hospital (Piacenza), and the Department of Experimental and Clinical Medicine, Unit of Audiology and Phoniatrics, University “Magna Graecia” (Catanzaro). Patients were included in the study if they: (a) had tinnitus for at least 3 months, (b) were older than 18 years, (c) spoke Italian fluently and (d) had no apparent cognitive impairment. The patients completed the questionnaires as part of routine clinical practice.
All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments. The study was performed in three ENT centres in Italy, namely Rome, Catanzaro and Piacenza. Heads of these centres (MD Alberto Eibenstein, MD Giuseppe Chiarella and MD Domenico Cuda) agreed on the procedures and provided access to tinnitus patients. Participation was voluntary and each patient gave written consent before filling out the questionnaires.
Tinnitus Sample Case History (TSCH)
Sociodemographic and clinical data were assessed with the Italian version of the TSCH. It was developed by the Tinnitus Research Initiative as an attempt to standardise the assessment of sociodemographic and clinical data in tinnitus research 30. The questionnaire consists of 35 items on background (i.e. age, gender), tinnitus history (i.e. loudness, pitch, percentage of awake time aware of tinnitus, hyperacusis) and related conditions (i.e. hearing impairment, noise annoyance, vertigo/dizziness).
Chronic Tinnitus Acceptance Questionnaire - Italian version (CTAQ-I)
The acceptance of chronic tinnitus was measured by the Italian version of the “Chronic Tinnitus Acceptance Questionnaire” (CTAQ-I). This is an adaption of the validated Italian version 31 of the “Chronic Pain Acceptance Questionnaire” (CPAQ) 32 for tinnitus, replacing the word “pain” with “tinnitus” or “ear noise”. The CTAQ-I consists of 20 items, rated on a 7-point Likert scale (0 = never true, 6 = always true) for rating tinnitus acceptance. Eleven items measure the extent of participation in normal daily activities regardless of acknowledged tinnitus (“activity engagement”, AE) and the remaining nine reverse-keyed items measure the willingness to have tinnitus present without trying to avoid or reduce it (“Tinnitus Willingness”, TW). The CTAQ-I total score ranges from 0-120, with a higher score indicating higher acceptance of tinnitus. A validation of the German version of the CTAQ (CTAQ-G) has shown an internal consistency of α = 0.85 29.
Tinnitus Handicap Inventory (THI)
The Tinnitus Handicap Inventory (THI) is a self-administered tool, widely used in tinnitus research and in clinical contexts, to assess the impact of the tinnitus in daily life. It consists of 25 items that can be divided in a functional, emotional and catastrophic subscale. Based on the total score tinnitus severity can be graded from slight (grade 1) to catastrophic (grade 5). Good reliability (α = 0.94) and validity was reported for the total score of the Italian THI version 33.
Tinnitus Questionnaire (TQ 12)
Tinnitus distress was also measured with the Italian 12 item short form of the Tinnitus Questionnaire (TQ 12-I) 34. For the TQ 12-I, good reliability and validity were reported. The total score allows the classification of the patients as compensated (0-7), moderately distressed 8-12, severely distressed 13-18, and most severely distressed 19-24.
Brief Symptom Inventory (BSI)
Mental health symptoms and psychological distress were assessed with the Brief Symptom Inventory. The BSI consists of 53 items to capture global psychological distress. Good reliability and validity for the subscales and total score were reported 35.
Short Form (36) Health Survey
The health status was measured with the Short Form Health Survey (SF-36), a broadly used, well established instrument to assess the Health-Related Quality of Life (HRQOL). The SF-36 consists of 36 items which can be divided into a physical and psychological total score. The subscale’s internal consistencies were tested in nine samples, showing a Cronbach’s α between 0.77-0.93. Good validity has been reported in several studies 36.
Psychometric values (means, standard deviations, item-total correlations) of the items are presented. A factor analyses (maximum likelihood, direct oblimin) with a fixed number of factors was conducted to investigate the proposed two-factor solution 29. Scree plots and Eigenvalues were used to determine the ideal number of factors. Reliability was evaluated by calculating Cronbach’s α (internal consistency) and item-total correlations. Validity was evaluated by two-sided Pearson correlations with the THI, TQ 12-I, BSI and SF-36 scores. Statistical analyses were conducted using IBM SPSS (ver. 22).
Of the initial 150 patients, 4 (2.6%) were excluded because their tinnitus lasted less than three months and another 5 patients (3.3%) because of fully missing CTAQ data. The remaining 141 patients were included in the study of which 47.5% were recruited in Piacenza, 37.6% in Rome and 14.9% in Catanzaro. Their mean age was 53.8 years and 55% were men. The mean tinnitus duration was 7.5 years and a large proportion of the sample reported tinnitus in both ears. More than half of the sample had subjective hearing problems and about a third reported physical discomfort because of surrounding sounds (hyperacusis). About a quarter of the sample had undergone several treatments due to their tinnitus. Overall, patients were aware of their tinnitus (75.4%) and were annoyed (48.9%) about their time spent awake over the last month. Based on the THI total score, tinnitus distress was graded as follows: 19.1% very mild, 25.5% mild, 31.9% moderate, 14.9% severe and 7.1% catastrophic. For details see Table I.
The mean, standard deviation and item-total correlation of each item included are presented in Table II. The mean total score was 73.6 (SD: 20.1), the mean “activity engagement” score was 42.4 (SD: 14.4) and the mean “tinnitus willingness” score was 31.2 (SD: 11.8).
We tested the proposed factor solution 29 by factor analysis (maximum likelihood). Bartlett’s test of sphericity (χ² (171) = 1096.34, p < 0.001) was significant and the Kaiser-Meyer-Olkin measure verified the sampling adequacy for the analysis (KMO = 0.82). Initial Eigenvalues indicated that the two factors explained 41.1% of the variance (factor 1: 27.7%, factor 2: 13.5%). The diagonals of the anti-image correlation matrix were between 0.78 and 0.92. We were able to reproduce the proposed two-factor solution using oblique rotation (oblimin). While the scree plot supported a two-factor-solution (Fig. 1), the Eigenvalues indicated a four-factor solution. An exploratory factor analysis (maximum likelihood) without a predefined number of factors resulted in a four-factor solution, explaining 50.5% of the variance. Yet, this solution contained multiple cross-loadings and an inconclusive factorial structure. In the further calculations, the two-factor solution was used. Table III shows the factor loadings for the two-factor solution after rotation.
Good internal consistency was found for the total score (α = 0.84) as well as for the factor “activity engagement” (α = 0.88) and the factor “tinnitus willingness” (α = 0.80). The exclusion of item 3 would slightly improve the Cronbach’s α for factor 1 (α = 0.89), but not for the total score, while the exclusion of item 7 would improve the internal consistency of both factor 2 (α =0.81) and the total score (α = 0.86). The item-total correlations were acceptable for all items, except item 3, 7, 11 and 16.
For the CTAQ-I total score high negative correlations with both the TQ 12-I and THI total scores and the respective subscales were found, which indicated good convergent validity. Furthermore, elevated tinnitus acceptance was correlated negatively with higher global psychological distress (BSI total score) and positively with emotional well-being (SF-36 emotional score). Only for the CTAQ-I subscale “activity engagement” significant positive correlations with physical well-being (SF-36) were found. The two subscales activity engagement and tinnitus willingness were weakly correlated to each other (r = 0.17, p = 0.045). Details are presented in Table IV.
Correlation with clinical data
Neither gender (p = 0.62) nor age (p = 0.68) correlated with the patients’ acceptance levels. While no correlation between the CTAQ-I total score and the tinnitus duration (p = 0.34) was found, acceptance was negatively correlated to the subjective tinnitus loudness (r = – 0.27, p = 0.002) and the percentage of time patients were annoyed by their tinnitus (r = – 0.57, p < 0.001). Additionally, the time patients were aware of their tinnitus was not correlated to their level of acceptance (p = 0.19).
Patients with a subjective hearing problem did not report significantly different CTQA-I scores than patients without subjective hearing problems (p = 0.69). No differences were found across the different subjective pitch-level (p = 0.82), and patients who experienced tinnitus with variable loudness did not significantly differ from those without varying tinnitus loudness (p = 0.86). On the other hand, patients with hyperacusis reported lower acceptance scores than patients without hyperacusis (66.4 vs 80.2 points; t = 3.9, p < 0.001). Acceptance significantly predicted tinnitus distress (R2 = 0.48, b = – 0.64, p < 0.001), even after including hyperacusis in the model.
The process of acceptance is increasingly gaining interest in the treatment of chronic tinnitus. Reliable and valid tools are needed to evaluate tinnitus acceptance in clinical practise and outcome research. The aim of the present study was to investigate the psychometric properties of the Italian version of the “Chronic Tinnitus Acceptance Questionnaire” (CTAQ-I) in a multicentre study in which 141 patients with tinnitus complaints from three study centres participated. The results of our study showed that the CTAQ-I is a reliable and valid measure for assessing the acceptance of chronic tinnitus.
To investigate the factorial structure of the CTAQ-I, we replicated the proposed two factor solution, but also calculated factor analyses with a three- and four-factor solution. The two-factor solution showed the clearest factor solution and accounted for 42.1% of the total variance; the results show an ever better fit than for the German version of the CTAQ. Although the 3- and 4-factor solutions explained slightly more variance, they also had several cross loadings and an inconclusive overall structure. We therefore decided to retain the original 2-factor solution. In conclusion, the results of our factor analyses support the two-factor structure, which is in line with the original pain acceptance questionnaire (CPAQ) 32 and the two previous validations of the CTAQ in English and German, who also reported a two-factor solution 29 (Moreland 2009, unpublished thesis).
The items that load on the factor “activity engagement”, for example, include the full engagement in life (item 9: “I lead a full life even though I have tinnitus”) and the pursuit of valuable everyday activities even if the tinnitus is present (item 8: “There are many activities I do when I experience tinnitus”). Other items assess the performing life’s demands regardless of the perceived tinnitus level (item 1: “I am getting on with the business of living no matter what my level of tinnitus is”).
The factor “tinnitus willingness” includes questions addressing the attempt to gain control over the perception of tinnitus itself (item 13: “Keeping my tinnitus level under control takes first priority whenever I am doing something”; item 14: “Before I can make any serious plan I have to get some control over my tinnitus”). Item 4 (“I would gladly sacrifice important things in my life to control this tinnitus better”) depicted the extent to which some patients feel defeated by their tinnitus and how much they value even partial personal influence. Other questions that influence this factor capture attitudes and behaviours, such as the avoidance of situations where, from the patient’s point of view, tinnitus may be worsening (item 17: “I avoid putting myself in situations where tinnitus might increase”), or the experienced need of controlling tinnitus related thoughts and emotions. The items of the factor “tinnitus willingness” clarify the central importance of overcoming tinnitus for many patients, and how much they align or change their behaviour accordingly.
Our results support McCracken et al.’s 32 construction of acceptance as involving both the giving up of the struggle to control tinnitus and pursuing normal life activities despite tinnitus. Nevertheless, the relationship between acceptance and control strategies requires further study 20, as well as the potential benefits of control strategies and avoidance-based coping, by distinguishing between short- and long-term effects.
In our study the total score of the CTAQ-I as well as both subscales (“activity engagement” and “tinnitus willingness”) showed good internal consistencies, which were comparable to the CTAQ-G 29. Items 3 and 7 slightly lowered the internal consistency of the respective subscale. However, their exclusion would only result in mild improvement and the two items are profound parts of the theoretical concept of acceptance. Item 7 also showed the lowest item-total correlation of all items. In the previous validation of the German CTAQ-G item 7 showed an acceptable item-total correlation (r = 0.44) 29, while no specific details were presented in the English validation (Moreland 2009, unpublished thesis). We therefore decided to keep both items in the questionnaire. Nevertheless, further research should critically review these items in larger international samples.
Construct validity was analysed by comparing the CTAQ-I with measures of tinnitus distress, psychological distress and quality of life. Increased tinnitus acceptance was associated with less tinnitus distress and less psychological distress, which is in line with previous studies on tinnitus acceptance 16 20 22 37.
Furthermore, as indicated by previous research on tinnitus acceptance 22 37, higher levels of tinnitus acceptance were also related to an increased quality of life. While in our study emotional well-being was significantly correlated to the total score as well as both subscales, physical well-being seemed to be related only to activity engagement. This was not unexpected since the subscale ‘activity engagement’ includes a more physical aspect of acceptance, while tinnitus willingness may be understood as a more cognitive approach.
In our sample, the level of acceptance was neither correlated with gender or age, as also reported by Westin, Hayes 19. Acceptance was negatively correlated with the subjective loudness of tinnitus, which is strongly related to the amount of tinnitus distress itself 38. In a recent study, tinnitus acceptance fully mediated the relationship between the subjective tinnitus loudness and tinnitus distress, even when controlling for baseline depression and anxiety 20. These results clearly indicate the role tinnitus acceptance may play in the understanding of subjective tinnitus distress.
We found no significant correlations between subjective hearing problems and tinnitus acceptance. As expected, patients with hyperacusis showed lower acceptance scores than patients without hyperacusis. This may be a fairly important finding, since hyperacusis is highly prevalent among patients with chronic tinnitus 39, and is strongly related to tinnitus distress 40, as well as to subjective tinnitus loudness and related comorbidities 41. For clinical counselling, it might be highly relevant to assess the grade of acceptance or experiential avoidance, as symptom-related anxiety and protracted avoidance behaviour resulting from tinnitus and hyperacusis can both lead to disabling situations.
As shown in previous tinnitus studies 42, the process of acceptance may also be influenced in treatments, which do not include specific acceptance-oriented methods (e.g. tinnitus counselling, Tinnitus Retraining Therapy (TRT) or elements of psychoeducation). Future tinnitus research should therefore focus on the conceptualisation of acceptance and experiential avoidance to increase the understanding of which factors may boost tinnitus acceptance within different types of treatments. The appraisal of tinnitus as a harmless – albeit disturbing – experience, may pave the way to acceptance of ear noise. The sensory experience of tinnitus cannot be separated from the emotional experience, and involves the senses, emotions, thoughts, actions and behaviours. Tinnitus patients with a pronounced state of suffering have not only to accept the tinnitus, but also come to terms with the tinnitus-associated cognitions and emotions, which play an important role in the acceptance of tinnitus. Patients may benefit from developing greater acceptance of thoughts and feelings associated with tinnitus 18.
To capture such a wide concept as acceptance in future tinnitus research, it might be worth considering a combination of measures that reflect relevant features of acceptance, experiential avoidance and related variables. In addition to cognitive variables such as catastrophising, the inclusion of personality traits 43 and tinnitus-related emotions may deepen our understanding of how patients cope with distressing tinnitus 6. We assume that tinnitus-associated prolonged anger, shame as well as self-blame 11, or the assignment of guilt to others, can also impair the development of an accepting attitude.
The CTAQ-I may be used as an assessment tool to evaluate the extent to which patients are able to adopt an accepting attitude towards tinnitus. Investigation of these aspects are worthwhile for better understanding helpful processes in tinnitus counselling, and is of practical use for further development of psychological therapies as well as for daily clinical work for all the various disciplines involved in tinnitus treatment.
There are some potential sources of bias. The data was self-reported, collected as part of routine clinical work. Since our sample is a population from clinical practice, we can cautiously assume generalisability for outpatients. The sample consists exclusively of patients with chronic tinnitus; the significance of the results found is therefore limited for acute patients. The investigation has a cross-sectional design, so that any statements about cause-effect relationships or about factors influencing acceptance are not possible. We are not able to investigate the relationship between tinnitus acceptance and audiological data, since only self-report questionnaires were used. Future work is needed to clarify this aspect, as well as to investigate the test-retest reliability of the CTAQ-I.
In contemporary theories on how patients adapt to chronic diseases, acceptance is emerging as a valuable concept. Tinnitus acceptance is considered to be an important source of therapeutic change in behavioural-based treatments as well as in professional counselling for tinnitus. Further research is needed to highlight the importance of acceptance for adjusting to a life with chronic tinnitus and to deeper examine the clinical implications for the treatment of tinnitus. Our results show that the CTAQ-I is a reliable and valid instrument to measure the acceptance of patients suffering from chronic tinnitus. The CTAQ-I can also be adopted as an evaluation instrument for therapy research with tinnitus patients.
