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.<br> 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).<br> 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.<br>Additional details about the data:<b>WHO created the data:</b> Prof. Vinaya Manchaiah at the University of Colorado School of Medicine. <b>WHAT the data files contain:</b> This data set contains pre-intervention, post-intervention (immediately after, 2-months after intervention, and 1-year after intervention) and weekly-monitoring data of the ICBT study. <b>WHEN the data was generated:</b> November 2020 to August 2022.<b> </b><b>WHERE the data were generated:</b> This study was conducted over the Internet by recruiting participants from all over the United States. However, the database was installed at Lamar University server when the data was generated. <b>WHY the data were generated:</b> This data was generated as a part of clinical trials. <b>HOW the data were generated:</b> This data was generated by means of administering the questionnaires online before, during and after the ICBT.
