The study followed an experimental-experimental design with a pre-test, post-test approach and included a control group. A total of 45 patients were purposefully selected and randomly assigned to either the experimental or control group, with each group comprising 15 individuals. Data was collected using post-traumatic growth inventory (Tedeschi and Calhoun, 1996). The findings revealed that both the group therapy based on Acceptance and Commitment Therapy (ACT) and Mindfulness-Based Cognitive Therapy (MBCT) were effective in promoting post-traumatic growth. Furthermore, there was no significant difference in the effectiveness of the two therapies in improving post-traumatic growth in patients with multiple sclerosis (p > 0.05). These results have important implications for psychologists and counselors involved in the treatment and rehabilitation of individuals with multiple sclerosis.</span></span></span></span></span></div> Post-traumatic growth, Group therapy based on acceptance and commitment, Mindfulness-based cognitive therapy, Patients with multiple sclerosis 274 286 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-269-2&slc_lang=en&sid=1 Fatemeh Fartoosi Fartoosi.fatemeh@yahoo.com 100319475328460010204 100319475328460010204 No Department of Health Psychology, khoramshahr International Branch, Islamic Azad University, khoramshahr, Iran Fardin Moradimanesh fmoradimanesh@yahoo.com 100319475328460010205 100319475328460010205 Yes Department of Psychology, Dezfol Branch, Islamic Azad University , Dezfol, Iran Parvin Ehteshamzadeh p_ehtesha85@yahoo.com 100319475328460010206 100319475328460010206 No Department of Psychology, Ahvaz Branch, Islamic Azad University, Ahvaz, Iran Fariba Hafezi f.hafezi1395@yahoo.com 100319475328460010207 100319475328460010207 No Department of Psychology, Ahvaz Branch, Islamic Azad University , Ahvaz, Iran
