Background & Aims: Multiple sclerosis is a chronic and debilitating disease of the nervous system. Psychological aspects are often ignored in chronic diseases, while most patients suffer from these psychological aspects that arise from chronic medical problems Perfectionism is the disposition to set high standards and strive for achievement, and the core of its lies highly rigid demands that set the occasion for inflexible rules and beliefs. . The present study was conducted with the aim of comparing the effectiveness of Rational Emotive Behavior group therapy and Reality group therapy on perfectionism in in patients with Relapse Remitting type Multiple Sclerosis in Iran.
Methods: This study was a semi-experimental type that carried out with pre-test, post-test ,control group and follow up. 60 members were selected from 300 of the Iranian MS Association, whose MS disease was diagnosed by a neurologist, were selected based on the research criteria with the purposeful sampling method and were divided into three groups through random replacement (using a table of random numbers) and after Random replacement, to comply with the principle of random application, again by chance one of the groups as the first experimental group under Rational Emotive Behavior therapy (n=20; the second experimental group under Reality therapy (n=20) and a control group (n= 20) were used to collect information including the Hill's Perfectionism Questionnaire as a resaerch tool . The study included three groups: group one received Rational Emotive Behavior Therapy (REBT) and group two received Reality Therapy for 12 weeks, with one 90-minute session each week. Group three received no intervention and served as the control group. After the intervention, all three groups were re-evaluated(post-test), and follow-up was conducted three months after the post-test.Data were analyzed using repeated measures analysiss
Results: Multivariate covariance analysis showed that the variance of perfectionism is explained by Rational Emotive Behavior group. therapy and Reality group therapy. In other words, these two methods were able to reduce the signs of perfectionism. Also, further analyzes showed that the average scores of the participants of the 1st and 2nd experimental groups under group rational emotional behavior therapy and reality therapy were different in three measurements of the perfectionism variable. The effect size of the difference according to the value of eta square (experiment 1: 0.586 and experiment 2: 0.761) was high. Comparing the averages of the three stages in the table below indicates that the average of the first evaluation is higher than the average of the second and third evaluation. At the same time, the average of the second evaluation is higher than the average of the third evaluation (p<0.01). Finally, both rational emotional behavioral therapy and reality therapy had a positive effect on perfectionism, but the difference between these two methods was not the same in terms of the index of stable changes and clinical significance.
Conclusion: Based on these findings ,it can be concluded that Rational Emotive Behavior group therapy and Reality group therapycan both be used as an effective treatment to reduce the perfectionism of MS patients .but Rational Emotive Behavior Therapy has been more effective to reduce perfectionism. The results of this study demonstrated that there were no significant differences in perfectionism levels among the three groups at the pre-test stage. However, the post-test and follow-up assessments revealed significant differences, indicating the effectiveness of Rational Emotive Behavior Therapy (REBT) in reducing perfectionism. These findings suggest that REBT can serve as a valuable intervention for individuals with multiple sclerosis (MS), particularly those who experience high levels of perfectionism, anxiety, stress, or other emotional and behavioral difficulties in their daily lives. By targeting irrational beliefs and promoting adaptive coping strategies, REBT offers a promising therapeutic approach for improving emotional regulation and overall psychological well-being in this population. Further research with larger sample sizes and extended follow-up periods is recommended to confirm and expand upon these findings According to the principles of Rational Emotive Behavior Therapy (REBT), unconditional self-acceptance is a key therapeutic component that was emphasized throughout the intervention sessions. Patients were encouraged to acknowledge that making mistakes is a normal aspect of the human experience, that perfection is unattainable, and that their self-worth is not defined by their actions, failures, or the challenges associated with multiple sclerosis. Within this framework, individuals may experience regret over past behaviors and learn from them without engaging in self-condemnation or global self-evaluation. Such global self-ratings are considered maladaptive, as they often lead to intense emotions such as shame, guilt, and depression, which may impede emotional development and hinder behavioral change in individuals with MS.The clinical trial is believed to lead to a betterunderstanding of how perfectionism can be treated and the specificity of different treatments.
