Aim: Neuropathic pains are common complications of chronic diabetes that have a negative effect on patients' mood. The present study, however, was conducted with the aim of determining the pure and combined effect of M1 and F3 anodic tDCS on reducing psychological distress in type 2 diabetes patients with neuropathic pain. Method: The study is a four-group double-blind randomized clinical trial. The statistical population of the study was all patients aged 45 to 65 years with type 2 diabetes who were members of the Bonab Diabetes Association in the winter of 2021 and spring of 2022, identified by specialists as having neuropathic pain. The research sample was 48 people selected in a purposeful way and according to the inclusion and exclusion criteria. Then, the subjects were randomly assigned to 4 groups. Patients in 4 groups received their own interventions for 12 sessions, three times a week. The data collection tool was the 42-item depression, anxiety, and stress scale (DASS). Results: According to the results, the average psychological distress in the post-test, 1-month follow-up, and 3-month follow-up phases, compared to the pre-test phase, was significantly reduced. However, there was no difference in the mean psychological distress scores between the other phases (post-test, 1-month follow-up, 3-month follow-up). That is, even up to the 3-month follow-up phase, the effect of the interventions remained. Conclusion: Therefore, the application of transcranial direct current stimulation, considering its therapeutic potential, can be expanded in people with diabetes.

Aim: This research was conducted with the aim of determining the effectiveness of cognitive rehabilitation and play therapy on improving the executive functions of children with brain tumors. Method: The study was a practical research and a time series quasi-experimental design with multiple groups. The sample included 45 children between 7 and 10 years old with brain tumors selected from Mahak Hospital purposefully and by considering the inclusion and exclusion criteria. The subjects were randomly replaced in 3 groups of 15 people (group 1: cognitive rehabilitation; group 2: cognitive rehabilitation with play therapy; group 3: control group). The experimental groups received relevant interventions in 8 sessions, and the control group did not receive any intervention. The pre-test, post-test and 1-month follow-up of the participants of all 3 groups were conducted with the Executive Function questioner (BRIEF). In order to analyze the data, split-plot ANOVA design (SPANOVA) with spss21 software was used.Findings: According to the results, the deficit of executive functions in children of both experimental groups was reduced compared to the control group and was stable in the follow-up. Conclusion: The result showed these interventions can be used for children with brain tumors. Of course, the use of rehabilitation therapy integrated with play therapy is more suitable for improving the cognitive skills of children with brain tumors.

Abstract: Introduction: Adults with attention-deficit/hyperactivity disorder (ADHD) have some impairment in emotional relationship which can be due to problems in emotional processing. The present study uses the event-dependent potential (ERP) method to investigate the neural correlations of the early stages of emotional face processing in the N170 component when observing faces with different emotions in adults with ADHD compared to adults without ADHD.Methods: A total of 12 adults between 20 and 42 years old (6 males and 6 females) with ADHD were compared with 12 adults without ADHD (6 males and 6 females). Participants identified faces with different emotions while their brain activity was recorded using the event-dependent potential method.Results: The results showed that the N170 component for a neutral face was significantly different both for women with ADHD in the P8 region and men with ADHD in the O1 region comparing to adults without the disorder. (P <0.05)Conclusion: The present study supports the notion that people with ADHD in the early stages of facial processing and facial expressions are different from people without the disorder, which can affect the interpretation of facial expressions and emotions.

Introduction: The present study is a quasi-experimental study with an inter-intra subject design aimed to determine the effectiveness of combining acceptance and commitment-based therapy and mindfulness-based stress reduction therapy on anxiety sensitivity and perceived stress in people with type 2 diabetes. Method: The sample consisted of 45 patients with type II diabetes purposefully selected from patients referred to laboratories in Mahshahr city. After matching, the patients were randomly assigned to 3 groups of 15 patients and the experimental groups received their group interventions in 8 sessions of psychological therapy and 10 sessions of individual neurofeedback training and the control group did not receive any intervention. Pre-test, post-test, and 2-month follow-up were performed with Floyd et al.'s (2005) Anxiety Sensitivity Questionnaire and Cohen et al.'s (1983) Perceived Stress Scale. Results: According to the results of SPANOVA analysis, both ACT + neurofeedback and MBSR + neurofeedback were effective in post-test and follow-up stages to reduce anxiety sensitivity and perceived stress. But while the effectiveness of both interventions in reducing anxiety sensitivity was the same, for perceived stress, the effect of MBSR + neurofeedback, both in the post-test and in the follow-up phase, was significantly greater than the effect of ACT + neurofeedback.

Aim: The aim of this study was to determining the net effect and combined effect of two Mindful Breath awareness and Muscle Relaxation (MBMR) and Cranio-Electro Stimulation (CES) techniques on improving the sleep quality of patients with type 2 diabetes mellitus. Method: The present study is a randomized, three-group, double-blind, clinical trial of mixed inter-intra-subject design. The sample of the study included 30 patients with type 2 diabetes who were purposefully selected from Bonab Diabetes Association and were randomly assigned to three groups of 10 people of MBMR, CES, and MBMR+CES and in 10 single sessions, they received their group related interventions. Patients sleep quality were evaluated in three stages: pre-test, post-test, and one-month follow-up, with Pittsburgh Sleep Quality Index (PSQI). The collected data were analyzed by SPANOVA test, analysis of covariance and Bonferroni's post hoc test. Results: According to the results, all three interventions used were effective in reducing sleep problems over time. The most immediate effect occurred with the lowest stability for MBMR treatment, and the highest effect and stability of the effect occurred for MBMR+CES combined therapy. Conclusion: Therefore, the study found the combined application of two techniques, MBMR and CES (20 minutes, 100 µA and 0.5 Hz), to be effective and safe for rapid and stable sleep quality improvement in patients with type 2 diabetes.

Introduction:The aim of the present quasi-experimental research with pre-test and post-test design with control group study was to examine the effectiveness of computer-assisted cognitive remediation on executive functions and cognitive abilities of students with diabetes. Method: 18 Students with diabetes were selected from the Diabetes Association of Bonab city and randomly assigned into two experimental and control groups of nine people. Executive functions and cognitive abilities of both experimental and control groups were measured with research tools in the pre-test and post-test steps. The tools used in this study were computer software for memory and attention refinement, the software version of the Wisconsin Card Sorting Test, and the Coglab software (change detection from the attention test set, and signal detection of Perception test set). For intervention, the experimental group was individually under cognitive remediation in 10 half-hour sessions (twice a week) by using attention and memory improvement software. Findings: Data were analyzed using one-way covariance analysis. The results indicated an increase in cognitive abilities (attention for the discovery of change and perception) in the experimental group. However, the applied intervention did not increase the executive functions of the experimental group. Conclusion:The study concluded that although the intervention and the number of meetings prescribed in this study were useful for promoting cognitive abilities, they did not have enough power to improve its executive functions.

Introduction: The present study, with emphasis on CaR-FA-X Williams model, investigates the intermediate role of over-general autobiographical memory on the relationship between impairment executive functions with ineffective problem-solving in depressed people.Methods: For this purpose, 56 subjects with major depression by sampling method during the period from April to September 2017 were selected . For data collection, after diagnosis of major depression by a psychologist, Autobiographical Memory Test, a problem-solving problem test and a Wisconsin card software were used. To analyze the research data using SPSS and IMOS software and path analysis method, structural equation modeling was used.Results: The results showed that the direct effect of executive function on problem solving with a value of 0/283 is not significant at the level of 0/05. The indirect effect of executive function on problem solving with a value of 0/130 is significant at the level of 0/05. The total effect of the executive function on problem solving is 0/413, which is significant at the level of 0/05. Therefore, due to the insignificant direct and significant effects of indirect effect, oral memory is a general mediator variable in the effect between the executive function on problem solving.Conclusion:Therefore, the present study, confirmed by the Williams CaR-FA-X model, showed that depressed people, due to their negative mood, and impairment in executive functions, have a particular problem in restoring their memoirs, and this is a problem in retrieval, solving problems It also affects their problems and makes them produce less effective solutions. Therefore, more generative of autobiographcal memory as a mediating mechanism in the relationship between impairment in executive function and ineffective problem-solving in depressed people.

Introduction: Manual preference in the students affects their learning in the school and daily life. Objective: The purpose the present study was to test whether there is a relationship between manual preference and sexuality with finger counting habits in (74) primary school children. Method: Manual laterality was evaluated with The Handedness Questionnaire of Chapman and Chapman (1987) and finger counting habits in children were examined with interview. Findings: The results indicated that whereas most left-handers started counting with the left hand, most of the right-handers started with the right hand. The transition between the two hands during the counting showed equal proportions of symmetry-based and spatial continuity-based patterns among the left-handers and right-handers. No significant difference was found between boys and girls in finger counting habits. These findings showed that manual laterality contributes to finger counting directionality. Conclusion: Taken together, these results indicate that finger-counting habits integrate biological and cultural information.

Introduction: Lateralization of the brain associated with cognitive functions. It is suggested that handedness is related to creative cognitive function as one of the lateralization results. This study aimed to compare the components of creativity among right-handed, left-handed and ambidexterity students. Methods: This study is an ex post facto research. The statistical population in this study consists of all high school students at Lamerd and Mohr cities in the second semester of the academic year 2013-14. To select target groups, two sampling methods were used. Group of 40 right handed students in the available method and ambidexterity and left-handed group are each separately 40 students in multi-stage random method, were selected. The subjects in this study responded to Edinburgh Questionnaire and the creativity test. Findings: The results of MANOVA analysis on average creativity scores and its components of students showed that the average of creativity and components of fluency and originality in right handed students are significantly lower than left-handed students, and the average of creativity and components of fluency, originality and flexibility in right-handed students are significantly lower than students who are ambidexterity. Conclusion: creativity and its components in ambidexterity and left-handed students are higher than those of right-handed students, it can be said that the right hemisphere stimulation and interaction in the two hemispheres may affect people's creativity.
