One of the disorders that has affected many individuals today is attention deficit disorder. the present study aimed to examine the effectiveness of repetitive transcranial magnetic stimulation (rtms) on obsessive-compulsive symptoms in adults diagnosed with attention deficit disorder. this study utilized a quasi-experimental design with pretest-posttest and a control group. the statistical population included all adults diagnosed with attention deficit disorder who visited psychological clinics in yazd, iran, in 2024. from this population, 30 individuals were selected through convenience sampling based on inclusion and exclusion criteria. participants were then randomly assigned to the intervention group (n = 15) and the control group (n = 15). the research instrument was the maudsley obsessive-compulsive inventory (moci). participants in the experimental group received 10 sessions of rtms, each lasting 20 minutes. data were analyzed using ancova in spss version 23. the results indicated a significant reduction in obsessive-compulsive symptom scores in adults with attention deficit disorder in the intervention group compared to the control group after receiving treatment (f = 23.22, p < .05). according to the effect size results, 71% of the variance between the intervention and control groups in obsessive-compulsive symptoms was attributable to rtms treatment. given the study’s findings, rtms may be an effective intervention for reducing obsessive-compulsive symptoms in adults with attention deficit disorder.
