Internet-based cognitive behavioral therapy for tinnitus in the United States (ICBT US Study): Long-term (1-year) outcomes

This data set was generated as a part of four clinical trials aimed at evaluating the efficacy of the Internet-based cognitive behavioural therapy for tinnitus in the US population. This is a combined data set from two pertest-post single group trials and two randomized controlled trials and contain data from individuals with tinnitus (n=449). The data of all the participants with tinnitus who completed the pre-intervention screening (i.e., baseline) measure including those who participated in the ICBT trials is included. However, the data of post-intervention (immediately after intervention, 2-months post-intervention, and 1-year post-intervention) are included from those who completed the post-intervention measure.

Individuals with tinnitus provided data for demographic questionnaire as well as several outcome measures. The primary outcome was a change in tinnitus distress (Tinnitus Functional Index; TFI). Secondary outcome measures included measures of anxiety (Generalized Anxiety Disorder; GAD-7), depression (Patient Health Questionnaire; PHQ-9), insomnia (Insomnia Severity Index; ISI), quality of life (EQ-5D-5L), tinnitus and hearing-related difficulties (Tinnitus and Hearing Survey; THS), tinnitus cognitions (Tinnitus Cognitions Questionnaire; TCQ). The weekly measures included measures of tinnitus severity (Tinnitus Handicap Inventory-Screening; THI-S) and newly developed tinnitus qualities (Tinnitus Qualities Questionnaire; TQQ). The primary and secondary outcome data were collected at 4-time points (i.e., T0 = pre-intervention baseline; T1 = post-intervention; T2 = 2-months follow up, T3 = 1-year post-intervention). In addition, weekly measures were collected at 8-time points (8 weeks) during the intervention (i.e., between T0 and T1).

This work was partly funded by the National Institute on Deafness and Communication Disorders (NIDCD) of the National Institute of Health (NIH) under the award number R21DC017214.
