Abstract

Objective: Compare the relative efficacy of DesyncraTM and Cognitive Behavioural Therapy (CBT). Design and study sample: Sixty-one participants were randomly assigned to receive either DesyncraTM (n = 29) or CBT (n = 32). Randomisation included stratification regarding current hearing aid (HA) use. Depending on group assignment, participants attended approximately 7–12 visits. Tinnitus distress was measured using the Tinnitus Questionnaire (TQ). Results: Mean TQ scores decreased post-baseline from 5–15 points across treatment arms and strata. Model-based findings for the no-HA stratum showed a difference of −2.0 TQ points favouring Desyncra at 24-weeks, with a 90% posterior interval varying from −5.4 points favouring Desyncra to 0.8 TQ points favouring CBT. For the HA stratum, results show a difference of −1.0 TQ points favouring Desyncra, with a 90% posterior interval ranging from −4.7 points favouring Desyncra to 2.9 points favouring CBT. Conclusions: The difference between Desyncra and CBT on average showed greater improvement with Desyncra in the no-HA stratum by about 2 TQ points. To the extent that the study sample represents a clinical population and recognising the assumptions in the design and analysis, these results suggest Desyncra is just as effective or more so than CBT in reducing tinnitus distress.
