Understanding user reactions and interactions with an Internet-based intervention for tinnitus self-management: Mixed-methods evaluation
Get PDFPurpose: Internet-based interventions have the potential to reduce the disparity in access to psychological therapy that people with tinnitus currently experience. One example is the Tinnitus E-Programme, which although freely available online, has not yet been formally evaluated. The purpose of this study was to evaluate past, current, and new users’ reactions and interactions with the Tinnitus E-Programme.Method: Study 1 used an online survey to gather past and current users’ reactions to, and interactions with, the intervention (n=27). Study 2 used interviews and a relaxation log to assess how new users implemented the skills they learned into their everyday lives (n=13). Results: Generally, users expressed positive views of the intervention content and design features. Users particularly valued the education about tinnitus and its management, and relaxation skills training, and use of these components was high. In contrast, user reactions to self-monitoring tools, an online support forum, and therapist support were mixed, and use was lower. Implementation was limited by instances of poor usability and accessibility, user engagement, and adherence to relaxation goals. Users’ perceptions of the interventions credibility and relevance, and beliefs regarding a negative impact on their tinnitus influenced engagement. Users in both studies identified several benefits gained, including functional and emotional management; self-efficacy for managing and coping with tinnitus; understanding tinnitus and its management; social support; and acceptance of tinnitus. Conclusions: Findings suggest that the intervention was acceptable to its target group but also highlighted some areas for improvement. These findings will be used to inform further optimization work
Protocol for a multi-centre randomised controlled stand-alone feasibility trial to assess potential effectiveness and cost-effectiveness of digital hearing aids in patients with tinnitus and hearing loss (the HUSH trial)
Get PDFBackground: The most common management strategy for tinnitus provided in UK audiology clinics is education and advice. This may also be combined with some form of sound therapy (e.g. digital hearing aids). While education and advice is generally provided by all clinics, there is a marked variability in provision of hearing aids that depends very much on clinical decisions. A recent Cochrane review concluded a lack of evidence to support or refute hearing aid use as a routine intervention for people with tinnitus and hearing loss. This lack of evidence is reflected in the inconsistency of tinnitus management in the UK. The aim of the HUSH trial is to determine the feasibility of conducting a definitive randomised controlled trial (RCT) of the effectiveness and cost-effectiveness of hearing aids for adults with tinnitus and hearing loss. Methods: This is a multicentre randomised controlled feasibility trial. Up to 100 adults, aged 18 and over, presenting to 5 UK audiology clinics with a complaint of tinnitus and measurable hearing loss are being randomised to receive either: i) education and advice (Treatment as usual), or ii) education and advice with digital hearing aids. Feasibility outcomes are being collected around recruitment, retention, patient and healthcare professional acceptability and clinical outcome assessment. Outcomes are being collected via postal questionnaire at 12 weeks post baseline. A nested interview study will supplement clinical and other outcome data, providing a detailed understanding of participants’ and audiologists’ experience of both tinnitus management and the research processes.Discussion: This feasibility trial will help us to (i) determine if it is feasible to conduct a multicentre RCT comparing treatment as usual and treatment as usual plus digital hearing aids, (ii) optimise the design of a future definitive, multicentre RCT, and (iii) inform which outcome(s) is/are relevant for patients. This work presents an important first step in determining the effectiveness of hearing aids as a tinnitus management strategy. Trial registration: ISRCTN1421841
A systematic review of techniques and effects of self-help interventions for tinnitus: application of taxonomies from health psychology
Get PDFObjective: Self-help interventions are followed by people independently with minimal or no therapist contact. This review aims to assess the effectiveness of self-help interventions for adults with chronic tinnitus and systematically identify the self-help techniques used. Design: Systematic review and application of health psychology taxonomies. Electronic database searches were conducted, supplemented by citation searching and hand-searching of key journals. Prospective controlled trials, which used measures of tinnitus distress, functional management, anxiety, depression, and quality of life, were included. Michie et al’s behaviour change techniques (BCTs) taxonomy and Taylor et al’s PRISMS taxonomy of self-management components were applied to describe interventions. Study sample: Five studies were included, providing low-to-moderate levels of evidence. Results: Randomized controlled trial studies were too few and heterogeneous for meta-analysis to be performed. Studies comparing self-help interventions to therapist-guided interventions and assessing non tinnitus-specific psychosocial outcomes and functional management were lacking. Fifteen BCTs and eight self-management components were identified across interventions. Conclusions: A lack of high-quality and homogeneous studies meant that confident conclusions could not be drawn regarding the efficacy of self-help interventions for tinnitus. Better reporting and categorization of intervention techniques is needed for replication in research and practice and to facilitate understanding of intervention mechanisms
Effectiveness of bimodal auditory and electrical stimulation in patients with tinnitus : a feasibility study
Get PDFAbstract: BackgroundTinnitus is a common symptom, affecting about 10-15% of the adult population. When input from the somatosensory system can influence and/or elicit tinnitus, this type of subjective tinnitus is called somatosensory tinnitus. Recently, a new type of bimodal neurostimulation treatment has shown promising results for a specific subgroup within the somatosensory tinnitus population. It is, however, not clear if this bimodal stimulation is also effective in patients with other types of subjective tinnitus. AimThe aim of this study was to evaluate the feasibility and efficacy of non-invasive bimodal auditory-somatosensory stimulation in reducing tinnitus severity among a general population of people with subjective tinnitus. MethodsChronic subjective tinnitus patients were recruited from the ENT department of the Antwerp University Hospital. Somatosensory stimulation was delivered by Transcutaneous Electrical Nerve Stimulation (TENS), and it was combined with auditory stimulation via headphones. The therapy comprised six sessions of thirty minutes twice a week for a period of 3 consecutive weeks. Follow up measurements were scheduled 9-12 weeks after the last treatment session. The change of the Tinnitus Functional Index (TFI) score, a questionnaire evaluating tinnitus burden and effects on the quality of life, was the primary outcome measure. ResultsTwenty-nine patients were enrolled in the study. A linear mixed-effects model was used to analyze the efficacy of bimodal treatment. The results of this analysis showed a statistically significant decrease (by 6, 9 points) in average TFI score at the follow up visit when compared to baseline. The ability to modulate tinnitus did not have an influence on the treatment results. ConclusionOur study showed that bimodal stimulation is a feasible and safe method of tinnitus treatment. The method might be an effective treatment for some participants with tinnitus, especially those who have accompanying neck/temporomandibular problems, although, the evidence from this trial is quite weak. Additional research is needed toward establishing the optimal treatment protocol, as well as selecting the most appropriate inclusion criteria
Understanding user reactions and interactions with an internet-based intervention for tinnitus self-management: mixed-methods process evaluation protocol
Get PDFBackground: Tinnitus is a common medical symptom that can affect an individual’s emotional and functional quality of life. Psychological therapies are acknowledged as beneficial to people with tinnitus; however, such therapies are not always readily accessible. With their global reach, automated Internet-based interventions have the potential to reduce the disparity in access to psychological support that people with tinnitus currently experience. However, the evidence on the acceptability and efficacy of these interventions is lacking. Process evaluations that develop an in-depth understanding of how users experience these interventions provide an essential first step when evaluating complex psychological interventions.
Objective: To describe the protocol for a study that will explore past, current, and new users’ reactions to and interactions with the Tinnitus E-Programme, an Internet-based intervention for the self-management of tinnitus.
Methods: Two parallel mixed-methods studies will be carried out with 2 different populations. Study 1 will use an online survey to gather past and current users’ views of the program. Study 2 will recruit new program users to take part in an interview and complete a relaxation log to explore how well they were able to implement the skills they learned during the program in their everyday lives. The findings from both studies will be triangulated to develop an in-depth understanding of the program’s mechanisms of impact and identify any implementation or contextual factors that strengthen or impede its delivery and functioning.
Results: Study 1 is open for recruitment with a projected completion in June 2016 and Study 2 was completed November 2015. At the time of submission, 36 participants have been recruited to Study 1 and 12 participants have taken part in Study 2.
Conclusions: Findings will inform the optimization of the Tinnitus E-Programme and guide future evaluation work to assess the program’s effectiveness as a therapy for people with tinnitus
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Intervention planning for the Tinnitus E-Programme 2.0, an internet-based cognitive behavioural intervention for tinnitus
Get PDFPurpose: The purpose of this study is to comprehensively describe the intervention planning process for the Tinnitus E-Programme 2.0, an Internet-based cognitive behavioral intervention for tinnitus. Method: Theory-, evidence-, and person-based approaches to intervention development were used. In Phase 1, quantitative systematic reviews were used to identify potentially effective intervention techniques and design features. Primary mixed-methods research involving adults with tinnitus explored the acceptability of the first version of the intervention. In Phase 2, person-based guiding principles highlighted key intervention design objectives and features to address needs of the intervention’s target group (identified in Phase 1) to maximize its acceptability, feasibility of delivery, and effectiveness. Theory-based “behavioral analysis” and “logic modeling” comprehensively described intervention content and potential mechanisms of action. From this planning work, a prototype intervention was developed. Results: The intervention design objectives outlined in the guiding principles were to (a) normalize tinnitus, (b) support users to maintain a regular relaxation practice, (c) minimize the worsening of users’ tinnitus sensation, and (d) ensure the intervention is accessible to those with hearing loss. Behavioral analysis and logic modeling identified intervention processes (e.g., illness perceptions, beliefs about consequences, skills, goals) and purported mediators (acceptance of tinnitus, negative thinking, use of the cognitive skills tools for managing negative thoughts, and practicing regular relaxation) hypothesized to facilitate reductions in tinnitus symptom severity. Conclusions: The guiding principles highlight key design objectives and features to consider when developing interventions for tinnitus. The logic model offers hypothesized mechanisms of action that can be tested in future process analyses.</p
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
