Tinnitus, described as the conscious perception of unwanted sounds in the absence of a corresponding external acoustic stimulus,
1 is a prevalent complaint and one of the most distressing audiologic symptoms.
2 Because no cure has been identified, managing tinnitus remains challenging and costly. The estimated health care cost of tinnitus is $660 per patient per year in the United States,
3 with an annual health care cost of £750 million (US $965 million) and resulting societal cost of £2.7 billion (US $3.5 billion) per year in the United Kingdom.
4 Tinnitus clinics are not always readily accessible because of service and geographic constraints.
5,6 Moreover, although various tinnitus management approaches exist, evidence for their efficacy is scarce.
7 To date, cognitive behavioral therapy (CBT), has the most evidence of efficacy in reducing tinnitus distress.
8 Despite positive outcomes, there is limited accessibility to CBT for tinnitus, largely because of a shortage of suitably trained clinicians.
5 To improve access to evidence-based tinnitus care, an internet-based cognitive behavioral therapy intervention (iCBT) for tinnitus was pioneered in Sweden.
9 An iCBT intervention aimed at a UK population was adapted
10 from previous versions of the Swedish program. Both feasibility
11 and efficacy
12 of the UK version of iCBT have been indicated. It is, however, not known how outcomes for tinnitus using iCBT compare with those of the individualized face-to-face (F2F) care that is typically provided in the United Kingdom. Previous study comparisons with iCBT used group-based CBT (GCBT) as the active control group.
