Translation and adaptation of three English tinnitus patient-reported outcome measures to Spanish

Rapid Assessment of Tinnitus Complaints with a Modified Version of the Tinnitus and Hearing Survey

The objective of this project was to establish cutoff scores on the tinnitus subscale of the Tinnitus and Hearing Survey (THS) using a large sample of United States service members (SM) with the end goal of guiding clinical referrals for tinnitus evaluation. A total of 4,589 SM undergoing annual audiometric surveillance were prospectively recruited to complete the THS tinnitus subscale (THS-T). A subset of 1,304 participants also completed the Tinnitus Functional Index (TFI). The original 5-point response scale of the THS (THS-T16) was modified to an 11-point scale (THS-T40) for some participants, to align with the response scale of the TFI. Age, sex, hearing loss, and self-reported tinnitus bother were also recorded. The THS-T was relatively insensitive to hearing, but self-reported bothersome tinnitus was significantly associated with the THS-T40 score. Receiver operating characteristic analysis was used to determine cutoff scores on the THS-T that aligned with recommended cutoff values for clinical intervention on the TFI. A cutoff of 9 on the THS-T40 aligns with a TFI cutoff of 25, indicating a patient may need intervention for tinnitus. A cutoff of 15 aligns with a TFI cutoff of 50, indicating that more aggressive intervention for tinnitus is warranted. The THS-T is a viable tool to identify patients with tinnitus complaints warranting clinical evaluation for use by hearing conservation programs and primary care clinics. The THS-T40 cutoff scores of 9 and 15 provide clinical reference points to guide referrals to audiology.

Skarzynski Tinnitus Scale: Cultural Adaptation and Validation to Brazilian Portuguese

Introduction  Tinnitus is a prevalent condition among many different populations. Since tinnitus is subjective, self-report questionnaires are one way of assessing how much the condition interferes with the quality of life of an individual. Objective  The aim of the present study was to translate and cross-culturally adapt the Skarzynski Tinnitus Scale (STS) into Brazilian Portuguese and validate its psychometric properties. Methods  The STS was translated and cross-culturally adapted using five main steps. Fifty-eight individuals who had continuous tinnitus were invited to complete the questionnaire. Pure tone audiometry (air and bone conduction) were also done. Results  No major changes were necessary in translating the scale. The overall score was 1.3 (range 0-4). Internal consistency was tested by Cronbach α, which ranged from 0.54 to 0.85. Differences between genders and between subscales and the total score were not significant. A statistically significant difference was only found in the coping subscale, in which normal hearing subjects had higher scores than those with hearing loss. Conclusion  The translation and adaptation of the STS established linguistic and cultural equivalence with the original. In addition, it exhibited good internal consistency. Our results suggest that the STS is suitable for use in a clinical setting.

Considerations When Designing and Implementing Pragmatic Clinical Trials That Include Older Hispanics

Introduction

Pragmatic clinical trials (PCTs) are designed to connect researchers with clinicians to assess the real-world effectiveness and feasibility of interventions, treatments, or health care delivery strategies in routine practice. Within PCTs larger, more representative sampling is possible to improve the external validity of the research. Older adults from underrepresented groups can benefit from PCTs given their historically lower engagement in clinical research. The current article focuses on older Hispanic adults with Alzheimer disease and related dementias (ADRDs). Older Hispanic adults represent 19% of the US population and have a higher prevalence of ADRDs than Whites. We provide data from 2 PCTs about the recruitment of older Hispanics with ADRDs and discuss unique challenges associated with conducting PCTs and propose strategies to overcome challenges.

Data and Methods

The first PCT outlined is the Patient Priorities Care for Hispanics with Dementia (PPC-HD) trial. PPC-HD is testing the feasibility of implementing a culturally adapted version of the Patient Priorities Care approach for older Hispanic adults with multiple chronic conditions and dementia. The second PCT is the Dementia Care (D-CARE) Study, which is a multisite pragmatic study comparing the effectiveness of a health care system-based approach and a community-based approach to dementia care to usual care in patients with ADRDs and their family caregivers.

Lessons Learned and Recommendations for Future Studies

The lessons learned are summarized according to the various stakeholders that need to work together to effectively recruit diverse participants for PCTs: individuals, health care systems, research teams, and communities. Individual-level considerations include communication, priorities, and flexibility. Health care system-level considerations are grounded in 4 principles of Community-Based Participatory Research and include collaboration/partnership, available resources, priorities of the health care system, and sustainability. Research team-level considerations include team members, intentionality, and communication. Community-level considerations highlight the importance of partnerships, community members, and appropriate incentives.

Discussion

PCTs provide a unique and potentially impactful opportunity to test interventions in real-world settings that must be culturally appropriate to reach underrepresented groups. Collectively, considering variables at multiple levels to address the needs of older adults with ADRDs is crucial, and the examples and suggestions provided in this report are a foundation for future research.

Rapid Assessment of Subjective Hearing Complaints With a Modified Version of the Tinnitus and Hearing Survey

Hearing difficulties are frequently reported by patients in audiology clinics, including patients with normal audiometric thresholds. However, because all individuals experience some difficulty understanding speech in noisy environments, it can be difficult to assess hearing complaints objectively across patients. Normative values help address this issue by providing an objective cutoff score for determining what is or is not clinically significant. The goal of this study was to establish normative values for the four-item hearing subscale of the Tinnitus and Hearing Survey (THS-H). Respondents completing the THS-H rate the level of difficulty understanding speech in the situations most commonly reported as being difficult: in the presence of noise, on TV or in movies, soft voices and group conversations. In this study, 22,583 US Service Members (SMs) completed the THS-H using an 11-point scale ranging from 0 (not a problem) to 10 (a very big problem). Responses to the four items were summed to produce values between 0 and 40. The distribution of the final scores was analyzed based on severity of hearing loss, age, and sex. Only 5% of SMs with clinically normal hearing scored above 27, so this score was selected as a cutoff for "clinically significant hearing problems." Due to its ease of administration and interpretation, the THS-H could be a useful tool for identifying patients with subjective hearing difficulty warranting audiological evaluation and management.

German Translation and Cross-Cultural Adaptation of the Limb Deformity-Scoliosis Research Society (LD-SRS) Questionnaire

Background: Patient-reported outcome measures are gaining increasing importance in clinical research and quality control. Clinical impairment through limb deformities can appear in various forms. This study aimed at translating and culturally adaptating the Limb Deformity-Scoliosis Research Society (LD-SRS) patient-reported outcome measure (PROM) into German by following the scientific rigor of the cross-cultural adaptation process as well as ensuring the reliability of the translated version. The LD-SRS is applicable in children and adults. Methods: The translation was performed in accordance with the creators of the LD-SRS following the Professional Society for Health Economics and Outcomes Research (ISPOR) guidelines for translation and cultural adaptation. Two forward translations were performed, and after a consensus meeting, a professional translator translated the PROM back to English. The creators reviewed the back translation of the preliminary German version. Thirty patients with upper and lower limb deformities participated in cognitive debriefing interviews. The version was proofread and, finally, the test-retest reliability was estimated. Results: The mean age was 19 years (range 6–61). Twenty-six patients (87%) completed the retest after 6 days (range 3–26). The internal consistency was estimated with a Cronbach’s alpha of 0.96 (range 0.94–0.97), and the intraclass correlation was 0.92 (range 0.89–0.94), indicating an excellent reliability. The scores were normally distributed. Thereafter, the German version was proofread and finalized. Conclusions: The German translation and cross-cultural adaptation of the LD-SRS score resulted in a high reliability and internal consistency. The German LD-SRS score is readily usable and may be applied in future studies of German-speaking limb deformity patients.

Sex-Specific Prevalence, Demographic Characteristics, and Risk Factors of Tinnitus in the Hispanic Community Health Study/Study of Latinos

PURPOSE

The aim of this study was to determine the prevalence of any and chronic tinnitus among female and male individuals from varied Hispanic/Latino backgrounds and to estimate associations between risk factors for chronic tinnitus.

METHOD

Our analysis used cross-sectional baseline data collected from 2008 to 2011 from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Prevalence estimates and multivariable logistic regression were conducted using survey methodology. Participants included 15,768 adults (8,229 women and 7,539 men) aged 18-76 years. The primary outcome of interest was chronic tinnitus, defined as self-reported tinnitus lasting ≥ 5 min at a time and at least once per week. We hypothesized that after adjusting for covariates, the risk factors of depressed and anxious symptoms, smoking history, hypertension, and noise exposure history would be associated with higher odds of chronic tinnitus.

RESULTS

Unstratified prevalence for any tinnitus was 32.9%, and for chronic tinnitus, it was 12.1%. Sex-stratified results demonstrated that 2,995 female individuals (36.4%) and 2,187 male individuals (29.0%) reported any tinnitus, and of these, 1,043 female individuals (12.7%) and 870 male individuals (11.5%) reported chronic tinnitus. In the fully adjusted model, depressed and anxious symptoms as well as recreational noise exposure were associated with higher odds of chronic tinnitus in female individuals (odds ratios [ORs] = 1.06, confidence interval [CI; 1.04, 1.07]; 1.02, CI [1.01, 1.04]; and 1.40, CI [1.20, 1.62]) and in male individuals (ORs = 1.06, CI [1.03, 1.08]; 1.05, CI [1.02, 1.08]; and 1.30, CI [1.05, 1.65]). Current smoking was a risk factor for chronic tinnitus in male individuals (OR = 1.53, CI [1.16, 2.02]).

CONCLUSIONS

Prevalence of any and chronic tinnitus in the HCHS/SOL baseline cohort is higher than that reported in previous studies, particularly among female individuals. Understanding risk factors associated with tinnitus is important for the development of culturally and linguistically appropriate public health programs that consider sex differences and promote lifestyle modifications known to lower the odds of experiencing tinnitus.

Internet-Based Audiologist-Guided Cognitive Behavioral Therapy for Tinnitus: Randomized Controlled Trial

Background

Tinnitus is a symptom that can be very distressing owing to hearing sounds not related to any external sound source. Managing tinnitus is notoriously difficult, and access to evidence-based care is limited. Cognitive behavioral therapy (CBT) is a tinnitus management strategy with the most evidence of effectiveness but is rarely offered to those distressed by tinnitus. The provision of internet-based CBT for tinnitus overcomes accessibility barriers; however, it is not currently readily available in the United States.

Objective

The aim of this study is to investigate the efficacy of internet-based CBT compared with that of weekly monitoring for the management of tinnitus in reducing tinnitus distress; reducing tinnitus-related comorbidities, including tinnitus cognitions, insomnia, anxiety, and depression; and assessing the stability of the intervention effects 2 months after the intervention.

Methods

A 2-arm randomized clinical trial comparing audiologist-guided internet-based CBT (n=79) to a weekly monitoring group (n=79) with a 2-month follow-up assessed the efficacy of internet-based CBT. Eligible participants included adults seeking help for tinnitus. Recruitment was conducted on the web using an open-access website. Participants were randomized via 1:1 allocation, but blinding was not possible. The study was undertaken by English or Spanish speakers on the web. The primary outcome was a change in tinnitus distress as measured using the Tinnitus Functional Index. Secondary outcome measures included anxiety, depression, insomnia, tinnitus cognition, hearing-related difficulties, and quality of life.

Results

Internet-based CBT led to a greater reduction in tinnitus distress (mean 36.57, SD 22) compared with that in weekly monitoring (mean 46.31, SD 20.63; effect size: Cohen d=0.46, 95% CI 0.14-0.77) using an intention-to-treat analysis. For the secondary outcomes, there was a greater reduction in negative tinnitus cognition and insomnia. The results remained stable over the 2-month follow-up period. No important adverse events were observed. Further, 16% (10/158) of participants withdrew, with low overall compliance rates for questionnaire completion of 72.3% (107/148) at T1, 61% (91/148) at T2, and 42% (62/148) at T3.

Conclusions

This study is the first to evaluate and indicate the efficacy of audiologist-delivered internet-based CBT in reducing tinnitus distress in a US population. It was also the first study to offer internet-based CBT in Spanish to accommodate the large Hispanic population in the United States. The results have been encouraging, and further work is indicated in view of making such an intervention applicable to a wider population. Further work is required to improve compliance and attract more Spanish speakers.

Internet-based cognitive behavioural therapy for tinnitus in Spanish: a global feasibility trial

OBJECTIVE

Internet-based cognitive behavioural therapy (ICBT) for tinnitus is an evidence-based intervention, but only available in a few languages. To increase accessibility, ICBT was translated into Spanish. This study's objective was to determine the feasibility of ICBT for Spanish speakers.

DESIGN

A single-group pre-test post-test design was used. Compliance, engagement, acceptance and outcome feasibility were measured.

STUDY SAMPLE

Forty-six Spanish speakers with tinnitus were screened. There were 32 participants meeting the eligibility criteria, with a mean age of 47 (±11) years. Of these 91% were Hispanic or Latino with 66% living in Spain and 34% living in South America.

RESULTS

Outcome feasibility was established, as a large pre- and post-test within-group effect size of d = 0.90 was found for tinnitus severity. Large pre- and post-test effect sizes were also present for the secondary outcomes of anxiety and depression with a medium effect for insomnia, health-related quality of life, and tinnitus cognitions. Intervention engagement and compliance were not optimal although no participants withdrew. Intervention acceptance rates indicated scope for improvement.

CONCLUSIONS

ICBT for Spanish communities appears to be feasible. A randomised controlled trial is required to further investigate the effects and identify ways of improving engagement and attracting Spanish speakers from different countries.

Audiologist-Supported Internet-Based Cognitive Behavioral Therapy for Tinnitus in the United States: A Pilot Trial

Background Patients often report that living with a condition such as tinnitus can be debilitating, worrying, and frustrating. Efficient ways to foster management strategies for individuals with tinnitus and promoting tinnitus self-efficacy are needed. Internet-based cognitive behavioral therapy (ICBT) for tinnitus shows promise as an evidence-based intervention in Europe, but is not available in the United States. The aim of this pilot study was to evaluate the feasibility of an ICBT intervention for tinnitus in the United States. Method This study reports the Phase 1 trial intended to support implementation of a larger randomized clinical trial (RCT) comparing ICBT to a weekly monitoring group. As a pilot study, a single-group pretest-posttest design was used to determine outcome potential, recruitment strategy, retention, and adherence rates of ICBT for tinnitus. The primary outcome was a change in tinnitus distress. Secondary outcome measures included measures of anxiety, depression, insomnia, tinnitus cognitions, hearing-related difficulties, and quality of life. Results Of the 42 screened participants, nine did not meet the inclusion criteria and six withdrew. There were 27 participants who completed the intervention, with a mean age of 55.48 (± 9.9) years. Feasibility was established, as a large pretest-posttest effect size of d = 1.6 was found for tinnitus severity. Large pretest-posttest effect sizes were also found for tinnitus cognitions and hearing-related effects, and a medium effect was found for insomnia and quality of life. Treatment adherence varied with a retention rate of 85% (n = 23) at post-intervention assessment and 67% (n = 18) for the follow-up assessment. Conclusions This pilot study supported the feasibility of ICBT for tinnitus in the United States. Ways of improving intervention retention and recruitment rates need to be explored in future ICBT studies. Protocol refinements that were identified will be implemented prior to further RCTs to investigate the efficacy of ICBT for tinnitus in the United States.

Dismantling internet-based cognitive behavioral therapy for tinnitus. The contribution of applied relaxation: A randomized controlled trial

BACKGROUND

Internet-based cognitive behavioral therapy (ICBT) for tinnitus is an evidence-based intervention. The components of ICBT for tinnitus have, however, not been dismantled and thus the effectiveness of the different therapeutic components is unknown. It is, furthermore, not known if heterogeneous tinnitus subgroups respond differently to ICBT.

AIMS

This dismantling study aimed to explore the contribution of applied relaxation within ICBT for reducing tinnitus distress and comorbidities associated with tinnitus. A secondary aim was to assess whether outcomes varied for three tinnitus subgroups, namely those with significant tinnitus severity, those with low tinnitus severity, and those with significant depression.

METHODS

A parallel randomized controlled trial design (n = 126) was used to compare audiologist-guided applied relaxation with the full ICBT intervention. Recruitment was online and via the intervention platform. Assessments were completed at four-time points including a 2-month follow-up period. The primary outcome was tinnitus severity as measured by the Tinnitus Functional Index. Secondary outcomes were included for anxiety, depression, insomnia, negative tinnitus cognitions, health-related quality of life, hearing disability, and hyperacusis. Treatment engagement variables including the number of logins, number of modules opened, and the number of messages sent. Both an intention-to-treat analysis and completer's only analysis were undertaken.

RESULTS

Engagement was low which compromised results as the full intervention was undertaken by few participants. Both the ICBT and applied relaxation resulted in large reduction of tinnitus severity (within-group effect sizes d = 0.87 and 0.68, respectively for completers only analysis), which were maintained, or further improved at follow-up. These reductions in tinnitus distress were greater for the ICBT group, with a small effect size differences (between-group d = 0.15 in favor of ICBT for completers only analysis). Tinnitus distress decreased the most at post-intervention for those with significant depression at baseline. Both ICBT and applied relaxation contributed to significant reductions on most secondary outcome measures, with no group differences, except for a greater reduction of hyperacusis in the ICBT group.

CONCLUSION

Due to poor compliance partly attributed to the COVID-19 pandemic results were compromised. Further studies employing strategies to improve compliance and engagement are required. The intervention's effectiveness increased with initial level of tinnitus distress; those with the highest scores at intake experienced the most substantial changes on the outcome measures. This may suggest tailoring of interventions according to tinnitus severity. Larger samples are needed to confirm this.

Features, Functionality, and Acceptability of Internet-Based Cognitive Behavioral Therapy for Tinnitus in the United States

Objective Although tinnitus is one of the most commonly reported symptoms in the general population, patients with bothersome tinnitus are challenged by issues related to accessibility of care and intervention options that lack strong evidence to support their use. Therefore, creative ways of delivering evidence-based interventions are necessary. Internet-based cognitive behavioral therapy (ICBT) demonstrates potential as a means of delivering this support but is not currently available in the United States. This article discusses the adaptation of an ICBT intervention, originally used in Sweden, Germany, and the United Kingdom, for delivery in the United States. The aim of this study was to (a) modify the web platform's features to suit a U.S. population, (b) adapt its functionality to comply with regulatory aspects, and (c) evaluate the credibility and acceptability of the ICBT intervention from the perspective of health care professionals and patients with bothersome tinnitus. Materials/Method Initially, the iTerapi ePlatform developed in Sweden was adopted for use in the United States. Functional adaptations followed to ensure that the platform's functional and security features complied with both institutional and governmental regulations and that it was suitable for a U.S. population. Following these adaptations, credibility and acceptance of the materials were evaluated by both health care professionals (n = 11) and patients with bothersome tinnitus (n = 8). Results Software safety and compliance regulatory assessments were met. Health care professionals and patients reported favorable acceptance and satisfaction ratings regarding the content, suitability, presentation, usability, and exercises provided in the ICBT platform. Modifications to the features and functionality of the platform were made according to user feedback. Conclusions Ensuring that the ePlatform employed the appropriate features and functionalities for the intended population was essential to developing the Internet-based interventions. The favorable user evaluations indicated that the intervention materials were appropriate for the tinnitus population in the United States.
