The aim of the present study is the predict of worry based on behavioral activation and inhibition systems, cognitive emotion regulation strategies and intolerance of uncertainty in students. In terms of objective, this study is off is study is the fundamental type, and in terms of data collection, it is of the correlation type. For this purpose, 200 students were selected using convenience sampling (available sampling) from Masters students at the Islamic Azad University of Tabriz in 2014-2015 school year. The participants were asked to answer the measures of behavioral activation and inhibition systems (BAS/BIS), Cognitive Emotion Regulation Questionnaire (SERQ), intolerance of uncertainty Scale (IUS) and the Penn state worry Questionnaire (PSWQ). Data were analyzed by the analysis of variance and stepwise regression. Results showed that there was a significant positive correlation between the variables of behavioral inhibition system, negative cognitive emotion regulation strategies, and intolerance of uncertainty in one hand, and worry in another hand (p<0.01), and there was a negative significant relationship between the positive strategies of cognitive emotion regulation and worry (p<0.01). These variables were able to predict 1/54 of the total variance of concern (p<0.001). In addition, the relationship between the behavioral activator system variable and worry was not significant. Worry is related to a variety of negative consequences, including a high degree of emotional reactivity and inefficient regulation styles. Thus, the findings of this study have practical implications in the clinical arena.

Abstract

the present study aimed to the comparison of the intolerance of uncertainty (IU) and short-term memory capacity in patients with obsessive-compulsive disorder and normal individuals. a total of 30 patients (16 female, 14 male) with obsessive-compulsive were selected using convenience sampling from the psychiatric clinics and centers of Tabriz were matched with 30 patients (16 females and 14 males) of normal individuals by demographic information, and all of them were assessed through Baher & Dougas’s intolerance of uncertainty scale and the Wechsler Digit span test subscales .Data were analyzed by multivariate analysis of variance (MANOVA) and as well as SPSS version 19. The results showed that there is a significant difference between the two groups in terms of IU (P<0/01) and the difference in patients with OCD is more than normal individuals. Also, there is a significant difference in terms of the short-term memory capacity (P<0/01) and the difference in normal individuals is more than patients with OCD . So it can be concluded that patients with OCD have less ability to tolerate uncertainty than normal people and short-term memory capacity in these patients is lower than normal people. Therefore, intolerance of uncertainty and low working memory capacity are two factors that may affect OCD symptoms and therefore exacerbate and perpetuate the disorder.

Obsessive–compulsive disorder (OCD) is one of the most common and disabling psychiatric conditions in adolescence, strongly associated with cognitive-emotional constructs such as thought–action fusion (TAF) and intolerance of uncertainty (IU). The present study aimed to compare the effectiveness of emotion-focused therapy (EFT) and metacognitive therapy (MCT) on these constructs among female high school students with OCD. The research design was quasi-experimental with a pre-test–post-test control group and a three-month follow-up. The statistical population included all female high school students in Babolsar during the 2023–2024 academic year diagnosed with OCD through psychiatric evaluation and clinical interviews. A total of 45 students were selected through purposive sampling and randomly assigned to three groups (15 EFT, 15 MCT, and 15 control). The research instruments included the Thought–Action Fusion Scale–Revised (TAFS-R) and the Intolerance of Uncertainty Scale (IUS). Both intervention groups received eight 90-minute sessions, while the control group did not receive any intervention. Data were analyzed using repeated-measures ANOVA and Bonferroni post hoc test. The results showed that both EFT and MCT significantly reduced TAF and IU compared to the control group (p < 0.01). Moreover, MCT was more effective in reducing TAF, whereas EFT had a stronger impact on reducing IU. These findings highlight the importance of applying emotion-focused and metacognitive approaches in improving cognitive-emotional mechanisms of OCD in adolescents and suggest tailored interventions based on patients’ specific needs.
