    2025
    This study aimed to determine the effectiveness of Acceptance and Commitment Therapy (ACT) on perceived stress, body self-concept, and repetitive negative thoughts in girls diagnosed with BDD. The research employed a quasi-experimental design with a pretest-posttest control group. The statistical population consisted of girls with BDD in Alborz City, Iran, in 2023. A sample of 30 participants was selected through purposive sampling and randomly assigned to the experimental group (n=15) and the control group (n=15). Data collection instruments included a demographic checklist, the short form of the Physical Self-Description Questionnaire (PSDQ-S), the Perceived Stress Scale (PSS), and the Repetitive Negative Thinking Questionnaire (RNTQ). The experimental group underwent eight 90-minute sessions of ACT, as proposed by Hayes et al. (2011), while the control group received no intervention. The collected data were analyzed using multivariate covariance (MANCOVA) analysis with SPSS-24. The findings indicated that ACT significantly reduced perceived stress, decreased repetitive negative thoughts, and improved various dimensions of body self-concept (including health, physical activity, coordination, athletic competence, body fat, physical appearance, flexibility, strength, endurance, and self-confidence) in girls with BDD (p< 0.01). These results demonstrate the efficacy of ACT in enhancing the psychological and physical well-being of individuals with BDD.

For the results, it showed that between problem solving scores (F = 18.82; P = 0.001), number of floors (F = 4.75; P = 0.031), cognitive flexibility remaining error (F = 34.4; P = 0.039) and impulse control (F = 59.7; P = 0.007) there is a significant difference between right-handed and left-handed people. In problem solving and flexibility, the superior right group performed better than the superior left. In impulse control, the left superiors performed better than the right superiors. The functioning of the brain hemispheres affects cognitive functions and cognitive information processing.
  21. Developing a Causal model of procrastination and burnout of medical laboratory employees of Isfahan province based on executive functions with the mediator role of emotion regulation
    2023
    This study aimed to investigate the interplay between executive functions, job burnout, and emotion regulation among medical laboratory personnel in Isfahan province. Employing a descriptive-postal research design and structural equation modeling (SEM), we examined a sample of 320 participants, selected through Cochran's formula, with 300 individuals ultimately included for data analysis. Data were collected through various instruments, including the Safari and Amirkhani Razaliqi organizational negligence questionnaires, Maslach's job burnout inventory, Gretz and Roumer's emotion regulation questionnaire, the Wisconsin Card Arrangement Test, and the Stroop Color Test.The findings revealed direct and significant relationships between negligence and job burnout with executive functions and emotion regulation. Moreover, mediation analysis demonstrated that emotion regulation played a significant mediating role between executive functions and job burnout (P < 0.01). These results suggest that fostering an environment that encourages emotional regulation in the workplace can aid employees in coping with stress and interpersonal conflicts. Organizations that prioritize the reduction of job burnout and negligence may witness improved task performance and self-regulatory behaviors among their employees. Consequently, training programs focusing on enhancing executive functions should incorporate strategies for addressing job burnout, negligence, and emotion regulation through therapeutic techniques.
  22. Developing a Causal Model of Social Anxiety of Students with Specific Learning Disorder Based on Emotion Regulation and Perceived Self-Efficacy: The Mediating Role of Emotional Intelligence and Early Maladaptive Schemas
    2023
    The present study was conducted with the aim of developing a causal model of social anxiety in students with specific learning disorders based on emotion regulation and perceived self-efficacy, taking into account the mediating role of emotional intelligence and early maladaptive schemas. The statistical population of this research was made up of all the students with specific learning disorder who referred to learning disorder centers under the supervision of Sanandaj city in the academic year of 1402-1401. The research sample included 360 8-12-year-old students (174 girls, 186 boys) with specific learning disorders, who were selected from the statistical population as a purposeful sampling, according to the acceptance of the parents and teachers of the students to participate in the research. In this research, the self-report version of Leibovitz Social Anxiety Scale for Children and Adolescents (LSAS-CA-SR), Emotion Regulation Inventory (ERC), Children's Trait Emotional Intelligence Questionnaire (TEIQUE-CF), Children's Self-Efficacy Questionnaire (SEQ-C) and children's schema questionnaire (SIC) were used. After collecting the questionnaires, analysis was done on the raw data using structural equation modeling and path analysis through SPSS 24 and Lisrel 8.8 software. The fit indices of the model were confirmed. Based on the results obtained, the variables of emotion regulation, perceived self-efficacy, emotional intelligence and early maladaptive schemas have a direct effect on the social anxiety of students with specific learning disorders. Social anxiety of students with specific learning disorder has a significant relationship with the mediation of emotional intelligence and early maladaptive schemas with emotion regulation, also, social anxiety of students with specific learning disorder has a significant relationship with the mediation of emotional intelligence and early maladaptive schemas with perceived self-efficacy (p<0.01). Therefore, in order to reduce the social anxiety of students with specific learning disorders, it is recommended that educators and experts formulate educational programs to increase adaptive emotion regulation strategies, increase the sense of perceived self-efficacy, and strengthen their emotional intelligence. Also, by adopting appropriate strategies and teaching parents, they can minimize the initial incompatible schemas of students with specific learning disorders.

  24. Developing a Causal Model of Social Competence Based on Interpersonal Cognitive Distortions and Cognitive Decision Making: The Mediating Role of Cognitive Fusion
    2022
    Background: As a dimension of mental health, social competence which is the ability to effectively manage social interactions plays a significant role in the success of individuals and organizations. The purpose of this study was to develop a causal model of social competence based on interpersonal cognitive distortions and decision-making styles with the mediating role of cognitive fusion. Method: In this descriptive and correlational study, 207 university staff including faculty members and administrative staff of the University of Kurdistan, were selected from the statistical population by simple random sampling. To collect the data, Felner's Social Competence Scale (FSCS), Interpersonal Cognitive Distortion Scale (ICDS), Decision Making Styles Questionnaire (DMS), and Cognitive Fusion Questionnaire (CFQ) were used. Then, the structural equation modeling (SEM) approach and SPSS and Lisrel 8.8 software were employed to analyze the data. Result: The results of this research showed that the proposed causal model confirms the relationship between interpersonal cognitive distortions, decision-making styles, cognitive fusion, and social competence. Moreover, interpersonal cognitive distortions and decision-making styles indirectly affect social competence through cognitive fusion. Conclusion: According to the findings, the social competence of the University of Kurdistan’s staff is influenced by interpersonal cognitive distortions, decision-making styles, and cognitive fusion. Training programs aimed to enhance the social competence of the staff can lead to the improvement of their social interactions and, as a result, improve their mental health.
  25. Visual-spatial attention and risk decision making of Parkinson's disease Patients in Comparison with healthy individuals and the effect of deep brain stimulation on it
    2022
    Background & Aims: In most Parkinson's patients, impairment in cognitive functions is clearly observed; This issue has become a serious problem in the quality of daily life of patients. In this research, first, the functions of visual-spatial attention and risk decision-making of patients with Parkinson's disease were investigated with healthy people, and then the effect of deep brain stimulation surgery on the functions of visual-spatial attention and risk decision-making of patients with Parkinson's disease was investigated. Materials & Methods: The present research method is descriptive and causal-comparative in terms of comparing Parkinson's patients with healthy people, and in terms of investigating the effect of deep brain stimulation surgery on visual-spatial attention functions and risk decision-making in Parkinson's patients, it is interventional and pre-test-type. The post-test was with the control group and with the follow-up phase. The research sample included 20 patients with Parkinson's disease, 8 of whom were candidates for deep brain stimulation surgery and 12 of whom did not need surgery. Demographic profile form, Mini-mental state examination, Simon task and modified Cambridge risk taking task were performed on sample people. For the first part of the study, 12 healthy people were randomly selected and their score in visual-spatial attention performance and risk decision making was compared with the score of patients in the pre-test stage. In the second part of the research, due to the limitation of the number of surgeries that one person is operated on each week, with each test of a candidate for surgery, tests were also taken from a healthy person and a sick person, and this time interval until the end of the research and for all Patients continued. Finally, after 3 months of the post-test, the follow-up phase was done. Data were analyzed using repeated measures analysis of variance and multivariate analysis of variance (MANOVA). Results The results showed that there was no significant difference between the average scores of visual-spatial attention performance in Simon's test in both healthy and sick groups (P<0.05); Also, there was a significant difference between the average scores of risk decision making performance in the modified Cambridge risk test in both healthy and sick groups (P<0.05). Finally, the results showed that deep brain stimulation was effective on the process of visual-spatial attention and risk decision-making in patients with Parkinson's disease (P<0.05). Conclusion These findings show that Parkinson's disease does not have much effect on visual-spatial attention functions, but it can affect the risk decision-making of people with Parkinson's disease; Also, performing deep brain stimulation surgery in Parkinson's patients did not have much effect on visual-spatial attention functions and risk decision-making of these patients.
