Purpose: The aim of this study was to present a causal model of job motivation with organizational-citizenship behavior (OCB) and the mediating role of organizational commitment in teachers in Ramhormoz, Iran. Methodology: The sample was 250 (125 females and 125 male) teachers, selected by stratified random sampling method, in the academic year of 2016-2017. The study was applied and research method was correlation using structural equations. The measurement tools used were Herzberg Job Motivation Questionnaire (1966), Oregon and Kanovsky (1996) OCB Questionnaire (1996), and Allen and Meyer (1990) Organizational Commitment Questionnaire (OCQ). Coefficients and structural equation modeling were used for data analysis. Findings: The findings in the direct paths of the model indicated positive direct effect of citizenship behavior on different aspects of organizational commitment and job motivation. Moreover, continuous commitment and emotional commitment had a direct effect on job motivation, but normative commitment did not have this effect. In the intermediary path of the model, citizenship-organizational behavior had positive indirect and negative indirect effects on job motivation, respectively through emotional and continuous commitment, but this effect was not significant through normative commitment. Discussion: According to the results of the research fitness of the proposed model increased after eliminating irrelevant paths and adding up new paths, so a good fit analysis was created for the final model.

Purpose: The aim of this study was to compare the effectiveness of transcranial magnetic stimulation (tms) and cognitive-behavioral therapy (cbt) in patients with depression in Tehran. Methodology: The purpose of the present study is to apply the pre-test and post-test with control group in terms of semi-experimental research method. The study sample consisted of 60 clients with depression who had been diagnosed by the Psychiatric Commission and admitted to psychology clinics in 2015. They were selected by random sampling and were randomly divided into three groups (two experimental and one control group) in each group of 20 persons. . Experimental groups in one group underwent cognitive-behavioral therapy for 12 sessions and the other group underwent transcranial magnetic stimulation for 20 sessions. Control group received no intervention. Data were analyzed using covariance analysis. Findings: The results showed that there was a significant difference between transcranial magnetic stimulation and cognitive-behavioral therapy in reducing depression in clients (P <0.01). Conclusion: Transcranial magnetic stimulation therapy and cognitive-behavioral therapy are effective in reducing depression in patients referred to psychiatric clinics.

The present study aimed to investigate the effectiveness of the Delis–Kaplan Executive Function System (D–KEFS) and Dawson–Guare program on neuropsychological functions in students with dyslexia. This was a quasi-experimental study with a pretest-posttest design, a control group, and a follow-up period. The statistical population included all boy and girl third-graders in Tehran within the 2018–2019 academic year. Based on the inclusion criteria, convenience sampling was employed to select 45 dyslexic students from all the boy and girl third-graders with dyslexia. The Raven IQ Test for Children (1983) and the Reading and Dyslexia Test (2016) was conducted for screening, and the Conners’ Continuous Performance Test (2004) was utilized for assessment before and after interventions. The first experimental group received 17 sessions based on the D–KEFS, whereas the second experimental group received 17 sessions in the Dawson–Guare Program. The ANCOVA was then used in SPSS-24 for data analysis. The mean of the post-test and follow-up scores of neuropsychological functions in the D–KEFS and Dawson–Guare Program groups significantly decreased compared to the control group (p<0.01). Moreover, the D–KEFS intervention improved neuropsychological functions further than the Dawson–Guare Program (p<0.05). Based on the findings, it can be concluded that there is a high correlation between enhancing executive skills in dyslexic children and improving their neuropsychological functions. It is possible to enhance neuropsychological functions, which underlie the reading skill, in dyslexic children through interventions that target a wide variety of executive functions.
