Abstract
Background & Aim: The importance of this research considering the consequences of anxiety disorders on the one hand and the cognitive processes and symptoms of panic disorder on the other hand, by comparing and then using the appropriate and accurate transcranial electrical stimulation intervention and transcognitive therapy, trying to improve these consequences. The aim of this study was to compare the effectiveness of transcranial electrical stimulation and metacognitive therapy on the cognitive processes of people with panic disorder.
Methods: This study was conducted using a semi-experimental method with a pre-test-post-test design on 45 people with panic disorder in 1401 in Mashhad. The research subjects were randomly assigned to three groups of 15 people with transcranial electrical stimulation and metacognitive therapy as an experimental group and a control group, and cognitive processes were measured using the questionnaire of agoraphobic cognitions and the questionnaire of panic disorder symptoms. Data analysis was done using the statistical test of analysis of covariance and with spss-24 software.
Results: The results of the study showed that by removing the effect of pre-test cognitive processes scores as a covariate, the main effect of transcranial electrical stimulation and metacognitive therapy on the cognitive processes of people with panic disorder in the post-test is significant. In other words, the results show that the observed difference between the average scores of the participants of the experimental group (-15.98) and the control group (-16.35) in terms of group membership in the post-test stage is significant with 95% confidence (p < 0.05).
Conclusion: These findings show that metacognitive therapy has a greater effect on reducing cognitive processes

Abstract
Background & Aim: Panic disorders are complex conditions that can be difficult to treat. Two methods that have shown promise in treating this disorder are brain stimulation, also known as transcranial direct current stimulation (tDCS), and metacognitive therapy. In order to determine the most effective approach, this study aimed to compare the impact of these two treatments on the metacognitive processes of individuals with panic disorder.
Methods: This study utilized a quasi-experimental pre-test-post-test design involving 45 individuals diagnosed with panic disorder. It was conducted in 2022 at the Mehr City Clinic in Mashhad. Participants were randomly assigned to three groups: two experimental groups consisting of 15 individuals each, one receiving tDCS and the other undergoing metacognitive therapy, along with a control group. The tDCS sessions were conducted individually and comprised of 16 sessions lasting 30 minutes each with a voltage of 2 milliamperes, while the metacognitive therapy sessions were conducted in groups over 10 sessions, each lasting 90 minutes. Metacognitive processes were assessed using Wells' Metacognitive Beliefs Questionnaire. Data analysis was performed using descriptive statistics and analysis of covariance with SPSS Version 24 software at a significance level of 5%.
Results: After the intervention, the mean and standard deviation of the scores for metacognitive processes were 73.81 ± 3.26 in the tDCS group, 64.33 ± 5.10 in the metacognitive therapy group, and 27.84 ± 3.26 in the control group. There was a statistically significant difference among the three groups (P = 0.001). The post-test phase showed a significant difference between the mean scores of metacognitive processes for participants in the experimental groups (−17.91) and the control group (−19.88) at a 95% confidence level (p < 0.05).
Conclusion: These findings suggest that metacognitive therapy has a more substantial effect on reducing metacognitive processes.
