Abstract

Introduction: This study aimed to investigate the effectiveness of transcranial direct current stimulation (tDCS) on improving ambiguity tolerance and reducing anger rumination in people with migraine.
Methods: The research method was quasi-experimental with a pre-test-post-test design with a control group. The statistical population included migraine patients referring to neurology clinics in Tehran. The statistical sample included 30 patients who were selected by convenience (voluntarily) and randomly assigned to two experimental groups (15 people) and control groups (15 people). At the beginning and end of the intervention period, participants answered the ambiguity tolerance questionnaires of Weden et al. (2003) and anger rumination questionnaires of Sakodolski (2001). The experimental group underwent tDCS intervention in 15 20-minute sessions, and the control group did not receive any intervention.
Results: Data analysis was performed with repeated measures test and SPSS-26 software.The results of data analysis showed that transcranial brain stimulation significantly increased tolerance for ambiguity and reduced rumination of anger in patients with migraine, and these effects remained up to one month after the end of the intervention (p<0.05).
Conclusion: These results indicate that tDCS can be used as an auxiliary method in improving tolerance for ambiguity and reducing rumination of anger in patients with migraine
