Purpose: One of the most common mental problems among tinnitus 
patients is anxiety. Therefore, the present study was Effectiveness 
of combined of cognitive therapy based on mindfulness with 
transcranial electrical stimulation on reducing anxiety in chronic 
tinnitus sufferers.
Materials and Methods: The research design was semiexperimental with a pre-test-post-test design with a control group, 
and the statistical population included all patients with tinnitus who 
referred to Tharullah Arak Medical Complex in 2022. The size of 
the statistical sample was 30 people (15 people in the experimental 
group and 15 people in the control group) from the mentioned 
statistical population, who were selected by available sampling 
method and randomly placed in two control and experimental 
groups. During 8 sessions, the experimental group was first
subjected to transcranial electrical stimulation for 20 minutes and 
immediately underwent cognitive therapy intervention based on 
mindfulness for 60 minutes, and the control group received only 
their usual treatment (transcranial electrical stimulation). In this 
research, Beck's anxiety questionnaire was used to collect data. In 
order to statistically analyze the obtained data, univariate analysis of 
covariance test was used .
Findings: The average scores of anxiety before and after the 
intervention in the experimental group were 10.93 and 6.80, 
respectively, and in the control group, 11.40 and 8.53, respectively. 
The results of covariance analysis showed that the average anxiety 
in the experimental group has significantly decreased after the 
combined intervention of cognitive therapy based on mindfulness 
with transcranial electrical stimulation in comparison with the 
control group (P<0.01).
Conclusion: The results of this research indicate that the combined 
intervention of cognitive therapy based on mindfulness with 
transcranial electrical stimulation has significantly improved 
anxiety, so the use of this intervention is recommended for chronic 
tinnitus sufferers.
