This study aimed to determine the effectiveness of mindfulness training on thought-action fusion, intolerance of uncertainty, and alexithymia in people with obsessive-compulsive disorder. The research method was semi-experimental with a pretest-posttest design and a control group. The statistical population included all women referring to psychology and psychiatry clinics in Shiraz in 1403. 30 people were selected as a sample using the available sampling method and were randomly assigned to two control and experimental groups (15 people in each group). The experimental group underwent mindfulness training in 8 weekly sessions, each session lasting 90 minutes. The two groups answered the Shafran and Rachman Thought-Action Fusion Questionnaires (STAF, 1996), Freeston et al. Intolerance of Uncertainty (IUS, 1994), and Bagby et al. Alexithymia (TAS-20, 1994) before and after the intervention. Data were analyzed using multivariate covariance test. According to the results obtained, controlling for the pretest effect, there was a significant difference at the 0.001 level between the mean of thought-action fusion, intolerance of uncertainty and alexithymia in the experimental and control groups. From the above findings, it can be concluded that mindfulness training is effective on thought-action fusion, intolerance of uncertainty, and alexithymia in people with obsessive-compulsive disorder.
