Introduction: In addition to physical complications, Covid-19 virus causes several psychological disorders. Depression is a common psychological complication of the virus that is associated with prolonged periods and a variety of symptoms. The aim of the present study was to investigate the effect of transcranial Direct Current Stimulation of the brain (tDCS) on depressive syndrome in improved individuals from Covid-19.Method: The present study was conducted in the form of a quasi-experimental design with random assignment of subjects, pre-test-post-test with control group and follow-up. The sample by available sampling method included 30 people who referred to clinics in Shiraz with depressive symptoms after developing Covid-19 and improving their physical symptoms and volunteered to participate in this study. Of these, 15 were placed in the experimental group and 15 in the control group. The instruments used in this study were Beck Depression Inventory and Treatment Sessions (tDCS) including 12 sessions of 20 minutes of F3 anodic stimulation and 2 mA cathodic FP2 stimulation. Data were analyzed by covariance method. Results: The results showed that there was a significant difference between the mean of experimental and control groups in the rate of depression in the post-test stage. Also, there is no significant difference between the symptoms of depression in the experimental group, in the post-test and follow-up stages.Conclusion: it seems that (tDCS) can reduce the depressive symptoms of people with Covid-19 and have good stability over time.

Aim: Depression is the most common mental disorder in the world. Mindfulness-based group cognitive therapy is one of the effective treatments, and transcranial direct-current stimulation is one of the new treatments for depression. This study aimed to compare the efficacy of these two therapies in reducing depression. Methods: This was a quasi-experimental study with pre-test and post-test with control group. Subjects were 60 students with depressive symptoms who were screened with General Health Questionnaire and selected by purposeful method based on Beck Depression Inventory(score above 15), and divided randomly into 4 groups of fifteen, including mindfulness-based cognitive therapy, transcranial direct-current stimulation, sham group(mock stimulation), and control group, and were reassessed in post-test using Beck Depression Inventory. The data were analyzed by repeated measurements design using SPSS software version 22. Results: The results showed that both experimental groups had a significant decrease in post-test depression scores(p<0/05), while there was no significant difference in sham and control groups. There was no significant difference between the two experimental groups in mindfulness-based group cognitive therapy and transcranial direct-current stimulation(p>0/05). Conclusion: Mindfulness-based group cognitive therapy and transcranial direct-current stimulation are effective in reducing depression in the nonclinical population.

Aim:The impairment in Cognitive functions is common symptoms of Depression. The purpose of this research is investigation of the effect of transcranial direct current stimulation (tDCS) on risky Decision-Making and reaction times (RT) in patients with Depression. Methods: Thirty university students with depressive symptoms who were referred to the Counseling Center of Azarbaijan Shahid Madani University were selected and randomly divided into two groups : experimental and control groups (n=15 per group). The experimental group received anodal-tDCS stimulation over the left DLPFC for two weeks, 5 days a week and each session for 20 minutes. Risky decision making and reaction time were assessed by Balloon Analogue Risk Task (BART) and reaction timer apparatus, respectively. The obtained data were analyzed using covariance analysis and paired t-test. Findings: The Results showed that the reaction times of both hands and feet was significantly faster in experimental group than sham group (p <0.05). Moreover, adjusted mean number of pumps (AMP) was lower in the experimental group than in the control group, during the BART task. Conclusion: according to our result, anodal tDCS stimulation reduced reaction time and decreased risk-taking behaviors.Therefore,transcranial electrical stimulation can be usedas a non-pharmacological and safe intervention to improve cognitive impairment to enhance the cognitive functions in people with depression.

Aim:Cognitive error of memory is an important issue that has been considered in recent years, and there are good reviews in this regard. The purpose of this study was to predict the cognitive error of memory based on academic self-efficacy, negative affect, and depression. Method: The present study was a descriptive correlational study.The statistical population of the present study was students of Payame Noor University of Ahwaz, 200 of them were selected by multi-stage random sampling. In this study, academic self-efficacy questionnaire (1396), positive and negative affection (1988), psychological stress (1995) and memory cognitive error (1396) were used. Data were analyzed using Pearson correlation and multivariate regression. Results: The results showed that there is a negative relationship between academic self-efficacy and cognitive error of memory, and there is a positive relationship between negative affection and depression and cognitive error of memory. Conclusion: The present study suggests that cognitive error of memory can be predicted based on academic self-efficacy, negative affective and depression variables.

Aim: The aim of this research was to determine the effectiveness of Clinical Creativity Therapy Model on improvement of executive function and decrease of depression in the depressed patients. Method: The research method was semi-experimental and study conducted in the form of a pretest-posttest with control group design and follow-up. The population was included the whole of Tehran depressed patients that refer to a psychiatric consultation centers in 1394and have document folder. 30 women and 20 men suffered from depression was randomly selected and replaced into treatment and control group. Research instruments were concluded Beck depression inventory (BDI-II), Torrance test of creativity thinking (Figural form), N-Back and Stroop test. A course of 20 include 10 session (2-hour-length session) was coducted of creativity therapy duration 4 weeks. Result: Analysis of covariance show that executive function and depression between treatment and control group is significant and effectiveness Clinical Creativity Therapy Model was stable in follow-up. Conclusion: results research show that Instrument of Clinical Creativity Therapy Model can improve the executive functions and decrease depression in the depressed men and women patients. Thus it is suggested that this model be use to improve the status depressed patient. The clinical creativity therapy model is useful and practical technique for psychologist and mental health specialists.

Aim:The purpose of this study was to investigate the relationship between physical complaints and depression symptoms in right and left handed individuals. Method: In this causal study, 120 female students with an average age of 25 years and 5 months were selected, of which 60 were right hands and 60 left handed. Left-handed people were available in the right hands, and right-handed men were selected randomly from the classes that were selected by the left-handed. Right and left-handed students were divided into two groups: depressed and unconfirmed. Beck Depression Inventory, General Health Questionnaire (GHQ-28), Edinburgh Hand Overweight Questionnaire, and researcher-made physical complaints assessment were used to collect information. For data analysis, binomial logistic regression was used. Findings: Findings showed that the score of physical signs of right-handed and left-handed hands is significantly related to physical complaints from the left side of the body. Also, this study showed that there is no significant difference between the depression score and the physical signs of right-handed and left-handed individuals. Conclusion: Regarding the high prevalence of physical complaints in the left side of the body, in depressed right and left handed students, the presence of these complaints on the left side of the body was considered as a symptom of depression.

Introduction: The aim of this study was to investigate the effectiveness of neurofeedback treatment on depression, anxiety, stress and psychosomatic abdominal pains in patients with clinical chronic psychosomatic abdominal pains in Shiraz. Methods: This research was a quasi-experimental study with pretest-posttest control group. The study population was all women with chronic psychosomatic abdominal pains among whom, 40 patients were selected for this study; ultimately, data were analyzed with 30 patients (experimental group=15 and control group=15). Participants were randomly assigned to 2 groups consisting of 15 participants who were divided into an experimental group and a control group. In this intervention, the experimental group was treated with neurofeedback for 10 weeks (3 times a week for 40 minutes) and the control group received no intervention and was put on a waiting list. Also, experimental and control groups completed the Depression Anxiety Stress Scales-21 (DASS-21) in pre-test and post-test. Multivariate analysis of covariance was used for data analysis. Findings: The results of covariance analysis showed that neurofeedback therapy had an impact on reducing anxiety and depression (P<0.001). In other words, 53% of depression variation and 57% of anxiety variation in patients were due to neurofeedback, but neurofeedback revealed no effect on stress. Conclusion: It was concluded that neurofeedback could significantly reduce depression and anxiety, but it had no effect on stress.

Introduction: The purpose of this study was to compare three groups of women with MS comorbid with, and without depression, and normal women. Method: This study was a causal-comparative research design. Among women who have referred to the MS Society in Markazi Province, 24 women comorbid with depression were diagnosed through the Beck Depression Inventory and Structured Clinical Interview for Depression (SCID). Furthermore, they were screened after the consideration of inclusion criteria. In addition, a group of patients with multiple sclerosis without depression symptoms among screened women who did not show depression symptoms were selected. Finally, a group of normal women based on inclusion and exclusion criteria was chosen. Stroop test, Tower of London test and Digit span were used for data collection. Data were analyzed using multivariate statistical analysis (MANOVA). Findings: The study showed that women who suffered from MS and depression in the same time had a weaker performance in Stroop test, Tower of London test and Digit span rather than two other groups. Also, this study showed significant difference in terms of performance tests between women with multiple sclerosis without depression symptoms and normal group. Conclusion: The findings indicated that in addition to the difference in executive functions in MS patients compared to normal subjects, depression can intensify this difference. Due to this effect, paying attention to depression in the design of treatment is recommended.
