Methods; The present study was an experimental study with pre-test, post-test, follow-up and control group. The study population consisted of children aged 7 to 12 years with ADHD. Available sampling method was used for sampling in this study. Sample size was selected based on the purpose and method of research (in experimental research, the sample size of at least 30 people in each group is recommended) 90 people. In this study, neurofeedback and motivational manipulation were performed on the intervention group as an intervention, each session was performed for 12 sessions and each session was performed for 45 minutes. Balloon risk test and delay discounting test were used to collect data in pre-test, post-test and follow-up stages and the data were analyzed using MANCOVA statistical method in SPSS-23. Results; By controlling the effects of pretest on posttest, the difference between the groups in the posttest was statistically significant between the variables of impulsivity and delay at the level of P <0.01 and between the variables of reward sensitivity at the level of P <0.05. The results also showed that neurofeedback method (M = 4.66) had a greater effect on reward processing than motivational manipulation method (M = 2.31) compared to the control group, which was significant at the level of P <0.01. But the difference between the mean of motivational manipulation (M = 2.31) in comparison with the control group was not significant. Conclusion; Voluntary activation of dopaminergic regions of the brain by neurofeedback and motivational manipulation leads to endogenous dopamine control in these structures, leading to successful regulation or inhibitory control and reduced cravings, which reduces impulsivity, delay discounting, and sensitivity to reward.","PeriodicalId":43609,"journal":{"name":"Iranian Journal of Psychiatry and Clinical Psychology","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44835794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dysregulation of both excitatory and inhibitory mechanisms N-Methyl-D-aspartic acid (NMDA) and γ-Amino butyric acid (GABA) are implicated in psychopathology of schizophrenia (4). GABAergic neurons alter dopaminergic function by inhibiting presynaptic dopamine release, particularly in the mesolimbic system (5). As gabaergic drugs act on the mesoprefrontocortical region and reduce dopaminergic activity, they may reduce both the positive and negative symptoms of schizophrenia (5, 6). Pregabalin is a GABA structural analog that binds to the alpha-2/delta subunit of voltage-dependent calcium channels and regulates the release of neurotransmitters such as glutamate, noradrenaline, and substance P in hyperactive neurons too (4,10). The role of pregabalin as an adjunctive substance in the treatment of psychotic symptoms in patients with schizophrenia has been evaluated in few studies (4-6, 11). These trials were associated with contradictory results partly due to differences in the sample size, patientschr(chr('39')39chr('39')) antipsychotic regimen and severity of psychotic symptoms at baseline. This pilot double blind, randomized clinical trial study was designed to investigate the efficacy and safety of pregabalin add on standard antipsychotic treatment in patients with chronic schizophrenia for 6 weeks. Methods: In a randomized, double-blind, placebo-controlled clinical trial, 48 inpatient male patients aged 18 to 65 years who fulfilled the chronic schizophrenia diagnosis, based on the structured clinical interview developed by the criteria from DSM-5(12), and had received antipsychotics for at least two years and were clinically stable on their current antipsychotic agent (no change in medication/dose of current antipsychotic agent) for a minimum of three months included in the study in Sari, Mazandaran, Iran.

So far, four studies in Iran have examined some of its psychometric properties in the population of medical and psychiatric patients - however, some aspects of its psychometrics and in the student population have not yet been adequately evaluated. The aim of this study is to examine more aspects of psychometric characteristics of PHQ-9 in Iran with a focus on the student population. Methods: In a descriptive study, 463 students of Guilan University of Medical Sciences in the academic year 2017-18were selected using convenience sampling and completed the research measures. The reliability of the Persian version of PHQ-9 was assessed using internal consistency and test-retest with two week interval. Its construct validity in the sample of students was evaluated by exploratory and confirmatory factor analyses. To evaluate its convergent validity, the second version of the Beck Depression Inventory (BDI-II), the depression subscale of the 21-item Depression Anxiety Depression Inventory (DASS-21), the neuroticism subscale of NEO Five Factor Inventory (NEO-FFI) and the negative affect subscale of the Positive Affect and Negative Affect Scale (PANAS) were used. The openness subscale of NEO-FFI and the positive affect subscale of PANAS were also used to assess the discriminant validity. Results: According to the findings, Cronbachchr('39')s alpha coefficient of 0.856 and intraclass correlation coefficient of 0.869 indicated, respectively, internal consistency and high test-retest reliability of PHQ-9. Exploratory factor analysis found that all questions were in one factor, accounting for 47.59% of the total variance. Confirmatory factor analysis showed that all questions were related to one factor. Positive correlation of PHQ-9 with BDI-II (r = 0.769), the neuroticism subscale of NEO-FFI (r = 0.508), the depression subscale of DASS-21 (r = 0.647) and the negative affect subscale of PANAS (r = 0.430) represented the convergent validity and its negative correlation with the positive affect subscale PANAS (r = -0.444) indicated its discriminant validity, while the openness subscale of NEO indicates NEO-FFI (r = 0.116) did not show a significant relationship. Conclusion: Overall, the findings of the present study suggest that PHQ-9 as a short-term measure has the potential to be used in clinical and research domains to screen, diagnose, and monitor clinical and/or subclinical depression in the student population.","PeriodicalId":43609,"journal":{"name":"Iranian Journal of Psychiatry and Clinical Psychology","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47515768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
