This study aimed to compare the effectiveness of mindfulness-based therapy and cognitive-emotional therapy on the cognitive fusion of autoimmune patients. In this study, the research method was experimental with a pre-test-post-test design and a control group. The statistical population included all autoimmune patients in Tehran who were referred to medical centers in Tehran in 2019, and 45 autoimmune patients using the purposive sampling method were selected. This number of samples was randomly divided into two experimental groups (15 people in experimental group 1 and 15 people in experimental group 2) and a control group (15 people). The experimental groups were then trained in mindfulness-based therapy and cognitive-emotional therapy (for each therapy, seven weeks and sessions in two hours). But the control group did not receive any training. The instrument used was the revised Cognitive Fusion Questionnaire (Gillanders, Bolderston, Bond, Dempster, Flaxman, et al., 2014). Data were analyzed using a multivariate analysis of covariance. Finally, the findings showed that the effectiveness of both mindfulness and cognitive-emotional therapies on cognitive fusion components are desirable, but according to the mean, cognitive-emotional therapy was more effective than mindfulness therapy on the component of cognitive fusion. In conclusion, these therapies will help to decrease cognitive fusion and improve cognitive defusion in autoimmune patients.
