The aim of this study was to determine the effect of Brainwave Entrainment in alpha band on working memory, anti-saccade and anxiety level of anxious participants. The present study is a quasi-experimental project of pre-test-post-test with control group. In this regard, after screening 250 university students, 30 anxious participants were selected by Beck anxiety inventory and randomly divided into one experimental group and one control group (15 groups each). All participants were assessed in the pre-test and post-test stages by the Corsi Blocks Tapping test, Antisaccade Task and Beck Anxiety inventory. Participants in the experimental groups received 10 Hz binaural beats for 30 minutes for 5 days a week in a period of one month. Data were analyzed using multivariate analysis of covariance. The findings showed that 10 Hz binaural beats (alpha bands) significantly improved pasticipant's working memory, increased antisaccade and decreased anxiety level. Therefore, brainwave entrainment in the alpha band is recommended as a non-invasive intervention method to reduce the level of anxiety and improve cognitive functions.

The aim of this study was to investigate the mediating contribution of obsessive beliefs in the relationship between sexual desire and marital satisfaction of women with obsessive-compulsive disorder. The research method was descriptive-correlation. The statistical population of this research was all married women suffering from obsessive-compulsive disorder who referred to the outpatient clinic of Hafez hospital and several private clinics in Shiraz in 2021, and 200 of them were selected by available sample. All of whom completed the Hulbert Index of Sexual Desire, Marital Satisfaction Questionnaire, Obsessive Beliefs Questionnaire, and Obsessive-Compulsive Inventory-Revised. The data were analyzed using correlation matrix, multivariate regression analysis and path analysis test. The main findings indicated that sexual desire had directly significant relation with marital satisfaction. Sexual desire indirectly had a significant relationship through the mediating role of obsessive beliefs with marital satisfaction. It seems that sexual desire directly and indirectly by mediating the role of obsessive beliefs predicted marital satisfaction. This study indicated the necessity of increasing awareness of beliefs, sexual knowledge and facilitating sexual counseling for married women.

The purpose of the present study was evaluation of the effectiveness of acceptance and commitment therapy on attention bias to threat and safety behaviors in students with social anxiety disorder (SAD) symptoms. The research design was quasi-experimental, pretest-posttest, follow-up with the control group. The statistical population of the research included all students aged 16-19 with SAD symptoms in Songhor city in 2022. By purposeful sampling method, 28 students were selected and assigned equally to experimental and control groups. Pictorial Dot Probe Task and Social Phobia Safety Behaviors Scale were used in three stages. The experimental group received eight 90-minute treatment sessions based on acceptance and commitment therapy protocol for social anxiety disorder in Adolescence (Alves et al.). Data were analyzed by mixed analysis of variance with repeated measure. The results showed that there was a significant difference in the average scores of the experimental group compared to the control group in the post-test stage. Also, therapeutic gains had maintained in the follow-up stage. Therefore, to reduce attention bias and safety behaviors in students with this disorder, acceptance and commitment therapy can be used by psychotherapists.

The purpose of this study was to compare the effectiveness of acceptance and commitment therapy (ACT) and emotional regulation (ER) on health anxiety and cognitive-emotional representations (CER) of recovered Covid-19 patients. The research method was a semi-experimental pre-test-post-test type with a control group. The research population included all those infected with the Covid-19 who visited health centers. By convenience sampling 75 of these people were selected, replaced randomly assignment in the experiment and control groups. The test of health anxiety and CER was performed in the pre-test and then, the ACT and ER was implemented in 8 sessions of 60 minutes (online). The obtained data were analyzed through the multivariate covariance test. The use of ACT had an effect on health anxiety in the post-test stage, but on reducing the perception of illness in the post-test stage, the test had no effect. ER had an effect on both of them.  It seems that the ER had a more effective result than the Act and it can be used in health and clinical centers to improve these patients.

The current research was conducted with the Meta-analysis method and aimed at combining the researches in the field of cognitive and meta-cognitive educational and therapeutic interventions on anxiety; therefore, the Hedges g effect size index was used as a standard scale in this research. The statistical population was the available research related to cognitive and metacognitive interventions on anxiety, which were available between the years 2001 and 2021 in the computer databases accessible Based on the defined inclusion and exclusion criteria of primary studies, 67 effect sizes from 63 primary studies were analyzed by CMA software. The size of the total combined effect was evaluated according to the large Cohen's criterion, which indicates the positive effect of various interventions on anxiety. In examining the role of moderating variables, the results showed the optimal effectiveness of therapeutic and educational interventions on types of anxiety, and no significant difference was observed between the two sexes in the effectiveness of the interventions. Finally, we can say  that cognitive and meta-cognitive therapeutic-educational interventions are one of the most effective types of interventions in improving all types of anxiety.

The aim of the present study was to investigate the effectiveness of the rehabilitation program on processing speed and attention of children with autism spectrum disorder. This research was semi-experimental with a pre-test, post-test, control group and follow-up design. The statistical population included all autistic students in the academic year 2022-2023 in Tehran. A sample of 20 students were selected by purposive sampling and randomly divided into control and experimental groups. The experimental group received 20 sessions of 30 mins cognitive rehabilitation intervention, twice per week while the control group did not receive any intervention. Integrated Visual and Auditory Continues Performance was used to collect data in three stages (before, after and two months later after the implementation of the cognitive rehabilitation program). The data analyses were done by repeated measurement test. The result showed that the cognitive rehabilitation program had effect on the processing speed and attention of students with autism spectrum disorder. Based on this finding, it is suggested that this program can be used to strengthen and improve executive functions of children with autism spectrum.

The aim of current study was to investigate the mediating role of resilience in the relationship between self-efficacy and post-traumatic growth among nurses during the COVID-19 pandemic. The research design was descriptive-correlational. From the mentioned, a total of 350  nurses selected via convinence sampling method and were examined by Tedeschi and Calhoun Post-traumatic Growth Inventory (PTGI), Scherer et al. General Self-Efficacy Questionnaire (GSE-17), and Conor-Davidson resilience scale (CD-RISK). To analyze the collected data Pearson correlation coefficient and Structural Equation Modeling were conducted. The results showed that direct effect of self-efficacy and the direct effect of resilience on the post-traumatic growth were significantly positive. Also, results showed that the mediating role of resilience in the relationship between self-efficacy and post-traumatic growth was significant. Based on the findings, it can be concluded that resilience and self-efficacy were important factors affecting nurses’ post-traumatic growth. Therefore, it is suggested that specialists by increasing resilience and self-efficacy through training and counseling interventions help nurses to manage the psychological truamas that resulted by covid-19 pandemic.

This study was aimed to investigate the effectiveness of behavioral intervention and support on externalized and internalized problems in students with hearing loss. This study was carried out using a semi-experimental method and a pre-test, post-test design with a control group. The statistical population of the research included students with hearing loss of Isfahan city, 30 of them were selected using the convenience method and randomly replaced in an experimental (15 people) and control (15 people) groups. Intervention was implemented for the experimental group during 10 sessions of 40 minutes, but no training was provided to the control group. In this study, the Achenbach & Rescorla Adolescent Self-Assessment Questionnaire was used. Data were analyzed using multivariate analysis of covariance. Findings showed that there was a significant difference between the behavioral problems of the experimental and control groups in the post-test phase. Behavioral intervention and support had a positive and significant effect on reducing externalized and internalized problems in participants. According to the results, it can be said that behavioral intervention and support leads to the improvement of behavioral problems, through controlling emotions and teaching adaptive behaviors of students.
