Objective: This study aimed to examine the effectiveness of neurofeedback in reducing symptoms of depression, anxiety, and stress in high school deaf girls. Method: A total of 24 deaf female students were randomly assigned to experimental (n=12) and control (n=12) groups. The experimental group received 15 neurofeedback training sessions targeting the F3 and F4 regions. Both groups completed the DASS-21 questionnaire before and after the intervention.. Results: Multivariate analysis of covariance indicated significant reductions in depression (F = 15.680, p<.05), anxiety (F = 5.991, p<.05), and stress (F = 6.100, p<.05) scores in the experimental group compared to the control group. Conclusion: Neurofeedback appears to be an effective intervention for improving mental health among deaf adolescents.

The psychological and social effects of the COVID-19 epidemic are potential and widespread, which affect people's mental health in the long term. The present study aimed to investigate the role of neuroticism in predicting psychological distress through perceived stress and loneliness in covid-19.Method: This research was carried out in the form of correlation and structural equations. The statistical population of the research was all the students of Azarbaijan Shahid Madani University, 300 of whom were selected through convenience sampling, and the neuroticism scale was from the short form of the Neo questionnaire, the Cohen et al.'s perceived stress questionnaire, the Kessler psychological distress questionnaire, and the loneliness scale. Social Emotional Assessment for Adults (SELSA-S) was administered to them. Then the obtained data were analyzed using Spss26 and Amos22 software.Results: The results showed that neuroticism is related to psychological distress through loneliness and perceived stress. Also, there is a positive and significant relationship between the components of loneliness, perceived stress, and neuroticism with stress, anxiety, and depression.Conclusion: Therefore, considering the increasing spread of psychological distress, it is necessary to reduce people's psychological distress by teaching self-care skills and stress management.

The purpose of the research is to analyze the effects of ethical leadership and organizational politics on individual and team creativity, focusing on the mediating role of knowledge hiding. The study is a descriptive-correlational survey and is applied in terms of purpose. The statistical population included employees of selected public organizations in the Eqlid County, totaling 950 individuals. 270 individuals were selected using a non-probability convenience sampling method based on the rule of thumb for SEM as the sample. To collect data, the following measures were used: Brown's et al. (2005) Ethical Leadership scale, the Organizational Politics scale by Kacmar and Carlson (1997), the Knowledge Hiding scale by Serenko and Bontis (2016), the Individual Creativity scale by Zhou and George (2001), and the Hanke's (2006) Team Creativity scale. The validity of scales was confirmed using the content validity, and the reliability was examined using Cronbach's alpha, yielding values of 0.89 for the Ethical Leadership, 0.82 for the Organizational Politics, 0.92 for the Knowledge Hiding, 0.87 for the Individual Creativity, and 0.85 for the Team Creativity. For data analysis, SEM and the AMOS software were used. The results of the study fitted the research model, indicating that ethical leadership and organizational politics have a significant negative impact on knowledge hiding. Additionally, knowledge hiding has a significant negative effect on both individual and team creativity of employees. By reducing knowledge hiding behaviors through ethical leadership and organizational politics, the level of creativity among employees at both individual and team levels increases.

The statistical population of this study includes all retirees in Zahedan city in 2021 – 2022, of which 123 people were selected as samples through the convenience sampling method. To collect data for this study, questionnaires on personality traits, cognitive health, perception of rejection, feeling of aging, and social isolation were used. Pearson correlation coefficient, stepwise multiple regression, and simple linear regression were used to analyze the research data. The results showed that the perception of rejection had a positive and significant correlation with neuroticism (p<.05) and a negative and significant correlation with extraversion, agreeableness, and conscientiousness (p<.01). However, there was no significant correlation between perceived exclusion and openness to experience. According to the results of the study, it can be concluded that personality traits play a significant role in predicting perceived exclusion, feeling of aging, and social isolation in retirees.

 Objective: This study aimed to examine the effects of reality therapy on improving psychological capital and sense of cohesion among Iranian Patients with Multiple Sclerosis. Method: This study was performed in Tehran in 2021. Sampling was employed to select 36 participants who completed the Psychological Capital Questionnaire and Sense of Cohesion Scale in the pretest, posttest, and onemonth follow-up stages. The participants of the experimental group underwent eight weekly 90-minute sessions to receive the online reality therapy; However, the control group received no intervention. Results: Data analysis showed a significant difference in psychological capital and sense of cohesion in the experimental group compared to the control group (P< 0/05). There was a significant difference in three subscales of psychological capital (i.e., self-efficacy, resilience, and hope) and two subscales of the sense of cohesion (i.e., perceptibility and controllability) in Patients with MS in the experimental group (P <0.05), but no significant difference in optimism (a subscale of the psychological capital) and significance (a subscale of sense of cohesion) (P> 0.05). Conclusion: Due to the effects of reality therapy on patients with multiple sclerosis, this psychological therapy can be employed to improve the psychological capital and sense of cohesion.

Objective : Despite significant antiemetic advances, almost 50 % of treated cancer patients still experience nausea and vomiting. The purpose of this study was to investigate the mediating role of avoidant coping in the relationships between psychological well-being and chemotherapy-induced delayed nausea in women with breast cancer in Shiraz. Method : The research method was descriptive-correlational. The statistical population of this study consists of women with breast cancer in Shiraz with an average age of 51 to 56 years. In this research, a non-random and voluntary sampling method was used; thus, 211 female patients with breast cancer treated by chemotherapy voluntarily completed the relevant questionnaires, which included psychological well-being questionnaire (Ryff, 1989), chemotherapy-induced delayed nausea questionnaire (Rhodes & McDaniel, 1999), and coping style questionnaire (Endler & Parker, 1990). The data were analyzed by AMOS software. Results : Research findings showed a negative and significant relationship between psychological well-being and avoidant coping style, and a positive and significant relationship between avoidant coping style and delayed nausea. The Sobel test confirmed the mediating role of avoidant coping style in the relationship between psychological well-being and delayed nausea. Therefore, it can be concluded that there was a relationship between psychological well-being and delayed nausea, with the mediation of avoidant coping style. Also, psychological well-being had an indirect effect on delayed nausea. Conclusion : Chemotherapy-induced delayed nausea can be reduced by improving coping skills and strategies and the psychological well-being of women with breast cancer.
