Objective: Stuttering is a type of communication and fluency disorder that hurts mental and emotional health. It is also associated with a significant increase in both trait and social anxiety. Studies on stuttering in adults have indicated the nature and impact of this phenomenon. In addition, some psychological aspects of this phenomenon remain vague and need further investigation. Therefore, the present study aimed to compare emotion regulation difficulties, repetitive negative thinking, and experiential avoidance between people who stutter and healthy individuals. Method : In this study, 101 people who stutter (43 females and 58 males, with a mean age of 29.55 ± 187 years), as well as 110 healthy individuals (74 females and 36 males, with a mean age of 25.57 ± 489 years) as participants were chosen using the convenience sampling method among those who referred to the speech therapy clinics of Tehran, Iran. Research instruments including the repetitive negative thinking inventory, Difficulties in Emotion Regulation Scale, and Acceptance and Action Questionnaire (AAQ-I) were used for data collection. Data were analyzed using multivariate ANOVA test and Multiple Regression Analysis. Results: The mean age of the participants was 29.55 years in the people who stutter and 25.57 years in the healthy individuals (P < 0.01). The present results indicated that the mean score of experiential avoidance was higher in the people who stutter (M ± SD: 35.74 ± 9.24) compared to the healthy individuals (M ± SD: 8.89 ± 31.11). Additionally, the mean score of emotion regulation difficulties was higher in the people who stutter (M ± SD: 88.75 ± 20.59) compared to the healthy individuals (M ± SD: 64.14 ± 94.94) (P < 0.001). However, there was no significant difference in the mean score of repetitive negative thinking between the people who stutter (M ± SD: 98.45 ± 25.85) and healthy individuals (M ± SD: 93.71 ± 25.24) groups (P > 0.05). There was a significant correlation between experiential avoidance and emotion regulation difficulties in people who stutter (P < 0.01). Experiential avoidance and repetitive negative thinking can significantly predict emotion regulation difficulties in people who stutter (R = 0.65, P < 0.01). Conclusion: People who stutter obtained higher emotion regulation difficulties and experiential avoidance scores than those without stuttering and A significant correlation between experiential avoidance and emotion regulation difficulties was found. Future studies should consider the role of emotion regulation difficulties and experiential avoidance in people who stutter., Competing Interests: None., (Copyright © 2024 Tehran University of Medical Sciences.

Background: In recent studies, the deficit in the cognitive process has been investigated as one of the etiological hypotheses in a wide range of obsessive-compulsive disorders (OCD). This study aimed to compare the effectiveness of acceptance and commitment therapy (ACT) and metacognitive therapy (MCT) on objective cognitive information processing style in obsessive-compulsive patients., Materials and Methods: This quasi-experimental study with a pre-test and post-test plan and a control group was conducted on 45 patients with OCD, matched with gender, age, and educational and marital status. The samples in three groups were selected using the convenience sampling method. Finally, the study participants were randomly divided into two experimental groups and one control group and assessed using Pacini and Epstein's rational experimental Inventory (REI) in two stages, pre-test, and post-test. The experimental groups received ACT and MCT weekly during eight and seven sessions and in a group., Results: The results showed that ACT and MCT are effective at a significant level in the objective cognitive information processing style of obsessive-compulsive patients ( P < 0.05). The post-test results showed that the effect of ACT in changing rational processing style is more effective than MCT treatment. Also, the effect of ACT on intuitive processing style changes was greater than on MCT treatment., Conclusion: The findings of this study indicate that ACT and MCT cause a significant change in intuitive style to rationalism in the thematic processing of cognitive information of obsessive-compulsive patients. According to the results, both methods of treatment improve the research variables in these patients., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Journal of Education and Health Promotion.)
