This research used a pretest-posttest study with control group. A multi-stage random sampling was used in 4 schools, among which 37 sixth-grade female students were randomly selected and assigned to two experimental (17 students) and control groups (20 students). Students in the experimental group participated in a mindfulness training course for 12 (120-minute) sessions for a month and a half. The study used Dennis and Vander Wal&#39;s Cognitive Flexibility Inventory (2010). The results of covariance analysis showed that there was a significant difference between the two groups in the scores of cognitive flexibility and due to the higher mean scores of the cognitive flexibility of the experimental group in the posttest (p> 0.05, p = 10.25), it can be stated that mindfulness training was effective in increasing students&#39; cognitive flexibility.</span></div> Mindfulness training, cognitive flexibility, students 131 140 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-152-3&slc_lang=en&sid=1 Sakineh Heidari 10031947532846001214 10031947532846001214 No Ph.D. student in Psychology, Faculty of Education and Psychology, Shahid Chamran University of Ahvaz, Ahvaz Gholamhossein Maktabi 10031947532846001215 10031947532846001215 Yes Associate Professor, Department of Psychology, Faculty of Education and Psychology, Shahid Chamran University of Ahvaz, Ahvaz Manijeh Shehni Yailagh 10031947532846001216 10031947532846001216 No Professor, Department of Psychology, Faculty of Education and Psychology, Shahid Chamran University of Ahvaz, Ahvaz Nasser Behroozi 10031947532846001217 10031947532846001217 No Associate Professor, Department of Psychology, Faculty of Education and Psychology, Shahid Chamran University of Ahvaz, Ahvaz
