Background: Managing chronic tinnitus is challenging and innovative ways to address the resulting health-care burden are required. Internet-based cognitive behavioural therapy (iCBT) for tinnitus shows promise as a cost-effective treatment option. The feasibility and effectiveness of iCBT in the United Kingdom (UK) are yet to be explored. Furthermore, it is not known if iCBT can be supported by an Audiologist rather than a Psychologist.Purpose: This study aimed to determine the feasibility of guided iCBT using Audiological support on tinnitus distress and tinnitus related comorbidities. Furthermore, it aimed to establish the feasibility of iCBT for tinnitus distress in the UK, by determining recruitment, attrition and compliance rates. Lastly it aimed to identify which aspects of the protocol require refinement for subsequent clinical trials.Research Design: A single-group open trial design was implemented. This study would serve as a pre-requisite study, to identify barriers, prior to undertaking effectiveness trials.Study Sample: Participants consisted of 37 adults (18 males, 19 females), with an age range of between 50-59 years. The mean pre-intervention tinnitus severity rating was 56.15 (SD 18.35) which is categorised as "severe tinnitus" as measured by the Tinnitus Functional Index. Five participants withdrew during the study and 29 of the remaining participants completed the post-intervention questionnaire.
Intervention:The guided iCBT intervention ran over an eight-week period and consisted of 16 obligatory modules and 5 optional modules. The intervention was designed to be interactive, interesting and stimulating. A key element was the provision of support from an Audiologist throughout the programme.
Data Collection and Analysis:Online questionnaires were used throughout the study. These were administered at baseline and post-intervention to determine attrition and compliance rates and to facilitate sample size estimates for further clinical trials.

In addition, a weekly questionnaire was incorporated to monitor change in tinnitus distress while undertaking the intervention.Results: Feasibility was established using an Audiologist to support this guided iCBT intervention, as a significant change post-intervention was found for tinnitus severity, as measured by the Tinnitus Functional Index and the Tinnitus Handicap Inventory screening version. The attrition rate was 22% and compliance was variable. Although these results were based on a small sample, they provide encouraging evidence for the feasibility of delivering iCBT trea...
