The Effectiveness of Group-based Cognitive Hypnotherapy on the Psychological Well-being of Patients with Multiple Sclerosis: A Randomized Clinical Trial

Multiple sclerosis is a chronic, demyelinating disease of the central nervous system mainly affecting young adults. In addition to physical problems, the patients suffer from many psychological problems affecting their psychological well-being. The aim of the present study was to determine the effectiveness of group-based cognitive hypnotherapy on the psychological well-being of patients suffering from multiple sclerosis. This study was designed as a clinical trial with a pretest-posttest control group. From 60 patients diagnosed with multiple sclerosis referred to Beheshti hospital in Yasuj, Iran, 45 patients who met the inclusion criteria were selected by the convenience sampling method. The patients were randomly assigned to intervention (23 individuals) and control (22 individuals) groups through stratified random allocation. After completing the Ryff Scales of Psychological Well-Being, the intervention group attended eight sessions of group-based cognitive hypnotherapy on a weekly basis. The control group did not attend any intervention sessions. At the end of the eight intervention sessions, both groups completed the Ryff's Scale of Psychological Well-being again. The collected data were analyzed using the SPSS software (Version 23). Analysis of Covariance (ANCOVA) and two-way Analysis of variance (ANOVA) tests were used in order to compare the groups. The results indicated that cognitive hypnotherapy had a significant effect on the total score of psychological well-being (F (45, 1) = 6.07, p = .018, eta 2 = 0.12) and the dimension of environmental mastery (p < .05). Therefore, it is recommended to use hypnotherapy to promote the psychological well-being of patients suffering from multiple sclerosis.
