Internet-based cognitive behavioural therapy for tinnitus in Spanish: a global feasibility trial.

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.
