Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In this randomised controlled trial, adults with diagnosed or self-reported tinnitus will complete a set of baseline questionnaires measuring tinnitus severity, psychological symptoms, and participant characteristics (i.e., demographics). Participants will be randomised into an intervention group (six weeks access to Tune Out) or control group (waitlist). Participants in both groups complete follow-up questionnaires at six weeks and three months to determine change in tinnitus severity and psychological symptoms.

The Tune Out program is an online self-guided, cognitive behaviour therapy (CBT)-based program that consists of educational content about tinnitus, CBT-based guidance, exercises, and a workbook. The program is a publicly available resource at www.tuneout.com.au. There are no strict engagement requirements for accessing the Tune Out program throughout the trial, however website analytics will be analysed to determine frequency of use, modules completed, and adherence to the program.

Comparator / control treatment
Participants in the control group will be waitlisted to receive the Tune Out program at the end of the trial. This reflects a typical approach to tinnitus management in which no action is taken and the tinnitus awareness / intrusiveness may lessen with time.

Efficacy
Statistical methods / analysis
A tentative a priori power analysis was performed in G*Power 3.1.9.7 (Faul et al., 2007) of the primary treatment outcome of tinnitus severity as measured by the Tinnitus Functional Index (TFI) suggested a total sample size of N=86 was required to detect a medium effect size (Cohen’s f = 0.25) at an alpha of 0.05 and power of 0.8 using repeated-measures, between-factors ANOVA.
Descriptive statistics will summarise the profile of study participants. These will be presented as frequencies and percentages for categorical variables; means, standard deviations, medians and ranges for variables measured on a continuous scale.
Quantitative efficacy data will be analysed using an intention to treat (ITT) analysis and linear mixed model approaches to determine indicators of reliable clinical change and the effect sizes in change in tinnitus severity pre- and post-intervention, and differences between intervention and control groups. Significant program impact will be determined by the significance and effect size of the change in the primary outcome variable.
Multivariate multiple linear regression will be conducted to explore possible impact of demographic characteristics and recruitment pathways on the efficacy of the intervention.
Baseline comparison of groups (those who provided follow-up data and those that did not) will be compared to determine if there are group differences that may explain loss to follow-up. Participants with missing data will be excluded from analysis however, sensitivity analysis will be used to quantify the effect of missing outcome data (e.g., using multiple imputation, regression adjustment or inverse probability weighting) on study results.
