Objective: Internet-based cognitive behavioural therapy (ICBT) for tinnitus is an evidence-based intervention, but only available in a few languages. To increase accessibility, ICBT was translated into Spanish. This study's objective was to determine the feasibility of ICBT for Spanish speakers.
Design: A single-group pre-test post-test design was used. Compliance, engagement, acceptance and outcome feasibility were measured.
Study sample: Forty-six Spanish speakers with tinnitus were screened. There were 32 participants meeting the eligibility criteria, with a mean age of 47 (±11) years. Of these 91% were Hispanic or Latino with 66% living in Spain and 34% living in South America.
Results: Outcome feasibility was established, as a large pre- and post-test within-group effect size of d = 0.90 was found for tinnitus severity. Large pre- and post-test effect sizes were also present for the secondary outcomes of anxiety and depression with a medium effect for insomnia, health-related quality of life, and tinnitus cognitions. Intervention engagement and compliance were not optimal although no participants withdrew. Intervention acceptance rates indicated scope for improvement.
Conclusions: ICBT for Spanish communities appears to be feasible. A randomised controlled trial is required to further investigate the effects and identify ways of improving engagement and attracting Spanish speakers from different countries.
