Abstract
The aim of current study was to investigation the Compare executive functions and cognitive interpretation bias and cognitive estimation in social anxiety disorder patients and healthy controls. In this study, the sample was 100 students with Purposive sampling method selected from public university from the city of Tehran. This means that the first explanation was given about the research and the cooperation to sample every five Social Phobia Inventory (SPIN), Cognitive estimation, Cognitive Abilities Questionnaire and، Interpretation bias Questionnaire. Then 50 people who score above the cut-off point in Social Phobia Inventory And in the range of subclinical and clinical, and 50 people who score below the cut-off point gained in social anxiety questionnaire formed the sample. The data was analyzed through multivariable analysis of variance. In sum, the finding of current study Interpretation bias in social phobia patients is higher than normal Individuals and cognitive estimation and executive functions in individuals with social anxiety disorder compared to healthy individuals is flawed. So that students with social anxiety disorder have lower performance in the components of other groups of students. This problem must be identified and targeted intervention.

Abstract
Depression is the most common mental disorder that disrupts patients’ lives and imposes costs on society. Recently, the use of biomarkers in the diagnosis and treatment of psychiatric disorders has been considered. The question is whether biomarkers derived from EEG are capable of separating depressed patients from healthy people. The objective of this study was to compare the power of different frequency bands in depressed and healthy individuals. The participants of this non-experimental study were selected using clinical criteria based on DSM-5 at Atieh Clinic in Tehran in 2016-2017 (29 women and 21 men who were depressed and 19 women and 31 men who were healthy). EEG was recorded in 19 channels and five frequency bands (delta, theta, alpha, beta and gamma) at rest (eyes closed) and during the Emtional Contineous Performance Task (ECPT). The results showed that at rest, the mean power was significantly higher in the depressed group only in the gamma band (Fz and Cz). Significant differences were also observed in theta (P8, O1 and O2), alpha (P4, P8 and O1), beta (Fp1, P3, Pz, and P4) and gamma (Fp1, Fp2, Fz and O1) during activity. Furthermore, mean powers in the depressed group were higher. It seems that EEG power during activity is a better discriminator than power in resting state and it could potentially be used as a biomarker for the diagnosis of depression.

Abstract
Risky behaviors are common in adolescent populations worldwide. It is believed that the disturbance in emotion regulation and emotional inhibition leads to an increase in risky behaviors in teenagers. The aim of this study was to evaluate the effectiveness of metacognitive interpersonal therapy on the cognitive regulation of emotion and emotional inhibition in adolescents with high-risk behaviors. The method of semi-experimental study with pre-test and post-test with a control group was conducted on all girls with high-risk behaviors who referred to Tehran counseling center in 2022. 30 teenage girls with risky behaviors were included in the study. Controlled study. Participants were selected by purposive sampling method and randomly divided into two experimental and control groups (15 people in each group). After conducting the pre-test using Carver and White Behavioral Inhibition/Behavioral Activation Scale and Gross and John Emotion Regulation Questionnaire, the experimental group received metacognitive interpersonal training for 8 sessions of 90 minutes each week, while the control group received no training. did not. To evaluate the effect of training, a post-test was taken from both experimental and control groups. The obtained data were analyzed using SPSS.23 software and multivariate covariance analysis method. The results showed that metacognitive interpersonal therapy caused a significant difference between the cognitive regulation of emotion and emotional inhibition in adolescents with high-risk behaviors. (P≥0.001). Based on these findings, it can be concluded that metacognitive interpersonal therapy has a positive effect on the cognitive regulation of emotion and emotional inhibition in adolescents with high-risk behaviors. Therefore, it can be said that this program can be used to help teenagers with risky behaviors.

Abstract
Cognitive biases are influential factors in explaining illness anxiety disorder, and understanding the existing biases in this disorder can contribute to more effective treatments. This study was conducted to examine the biases of attention, interpretation, and memory in individuals with and without illness anxiety disorder. The sample consisted of 142 participants who voluntarily participated in the research from across the country. In this study, differences in information processing between the two groups were assessed using the Health Anxiety Questionnaire, Beck Depression Inventory, and computer-based tasks measuring attention bias, interpretation, and memory. The data obtained from the research were analyzed using independent t-tests and analysis of covariance (ANCOVA) with the statistical software SPSS 26.The results showed that individuals with illness anxiety disorder had a greater tendency to focus on threatening cues compared to those without the disorder and interpreted ambiguous health-related information more negatively. However, no significant differences were observed between the two groups regarding positive interpretation bias. Additionally, individuals with illness anxiety recalled disease-related information more effectively. The findings indicate that individuals with illness anxiety display biases in attention, negative interpretation, and memory concerning health-related information. This research emphasizes the importance of identifying and targeting these biases in psychological treatments and suggests employing intervention methods such as cognitive bias modification to directly affect these biases due to their role in the formation and persistence of illness anxiety.

Abstract
| The present study aimed to investigate the effectiveness of mindfulness-based cognitive therapy (MBCT) in reducing cognitive fusion and interpersonal needs among students experiencing suicidal ideation. Employing a quasi-experimental design with pre-test, post-test, and follow-up assessments, participants were selected based on predefined criteria and randomly assigned to intervention and control groups. The intervention group received MBCT sessions, and data were analyzed using covariance analysis (ANCOVA). Results demonstrated that MBCT significantly decreased overall cognitive fusion, particularly the fusion component, and significantly reduced total scores of interpersonal needs, including perceived burdensomeness and thwarted belongingness. Additionally, a significant reduction in the severity of suicidal thoughts was observed in the intervention group compared to controls, whereas changes in cognitive defusion were not statistically significant. Follow-up data indicated that the positive effects of the intervention were maintained to a satisfactory degree over time. These findings support the clinical utility of MBCT as an effective intervention to improve maladaptive cognitive and interpersonal processes associated with psychological vulnerability in at-risk students. The study underscores the potential of MBCT in suicide prevention and mental health promotion, and recommends further research with larger samples and integrative interventions to explore underlying mechanisms and long-term efficacy. |
