Introduction: Obesity is one of the diseases whose prevalence has been accelerating over the past decades. It is estimated that about 1.2 billion people in the world are obese or overweight. In Iran, 5.5% of children and adolescents under 18 years of age and 21.5% of people over 18 are obese. Recently, mindfulness has attracted much attention in the field of obesity and overweight. The intervention, along with mindfulness meditation, to increase overall psychological and physiological self-regulation is perfectly commensurate with the cognitive, emotional, physiological, and behavioral dysregulations observed in eating disorders, especially in the case of impulsive overeating. Considering the effect of negative thoughts and beliefs on overeating behaviors and subsequent overweight, and on the other hand, the role of cognitive fusion as an essential and determining factor in the negative evaluation of disturbing thoughts, the role of cognitive fusion can be added Checked the weight. Recently, in line with   health professionals’s efforts, one of the effective ways to prevent and treat obesity and reduce its psychological, social, and economic consequences is to consider psychological treatment programs and other medical and sports treatments. In recent years, there has been a great deal of discussion about mindfulness-based therapeutic interventions. These treatments are known as the third wave of behavioral therapy. Acceptance and Commitment Therapy is one of the most common third-wave therapies for the behavioral therapy and aims to help clients achieve a rich, valuable, and satisfying life through psychological resilience. Emotion regulation training is one of the emotion-based therapies that can affect   people’s psychological symptoms with obesity and has been less considered by researchers so far. This study aimed to compare the effectiveness of group therapy based on ACT and emotional regulation on cognitive fusion, mindfulness, and emotional regulation in obese women.
Methods: The present study was an interventional study with a pre-test/post-test design that was conducted in 2019 on obese patients referred to psychiatric and psychology clinics in the west of Tehran. The selection of the intervention group was as follows: The subjects were invited to participate in the study in coordination and consultation with the clinic officials and according to the inclusion criteria. Then, 45 patients were selected by purposive sampling method and randomly divided into three groups of 15 (acceptance and commitment based experimental group, emotion regulation training experimental group, and control group). First, the necessary information about the study’s objectives was provided to the patients, and they entered the study of their own free will. Finally, informed consent was obtained from all subjects. Criteria for entering this study include age over 16 years, being overweight, not having a psychological disorder, and not receiving any other psychological treatment. Exclusion criteria were unwillingness to continue cooperation and a maximum of two sessions of absence for the patient. Then, 12 120-minute sessions of emotion regulation training and acceptance and commitment therapy were performed in the experimental groups. Data were collected using the Cognitive Fusion Questionnaire, Mindfulness Questionnaire, and Emotion Regulation Difficulty Scale. Data were analyzed using analysis of covariance with SPSS-21 software.  The Kolmogorov-Smirnov test checked the normality of data distribution. Then, analysis of covariance was used to examine the differences between the two groups in terms of research variables.
Results: The   covariance analysis results showed that the difficulty in regulating emotion, mindfulness, and cognitive fusion after therapeutic interventions was significantly different between the three groups (P=0.0001). Then, the Fisher post hoc test was used to examine which of the two groups are different. These test results showed that the difference between each of the groups of emotion regulation training and treatment based on acceptance and commitment with the control group is significant, but the results of the two types of treatment are not significantly different.
Conclusion: The research results showed that emotion regulation training and acceptance and commitment-based therapy effectively reduce cognitive fusion and improving emotion regulation and mindfulness in obese people. Therefore, considering the confirmation of the effect of emotion regulation training based on acceptance and commitment in the treatment of obesity, it is suggested that therapists consider these two therapies in reducing cognitive fusion and improving emotion regulation and mindfulness of overweight people.
