The main purpose of the present study was to investigate psychometric properties of the Perceived Stress Reactivity Scale (PSRS, Schlotz, Yim, Zoccola, Jansen & Schulz, 2011) among Iranian university students. 324 university students (130 male, 194 female) completed the PSRS and the Emotional Adjustment Measure (EAM, Rubio, Aguado, Hontangas & Hernandez, 2007). The confirmatory factor analysis method and internal consistency were used to compute the PSRS's factorial validity and reliability, respectively. Also, in order to examine the construct validity of the PSRS, we computed correlations between different dimensions of PSRS with emotional adjustment. The results of confirmatory factor analysis indicated that 5-factor structure of the PSRS consisted reactivity to work overload, reactivity to social conflicts, reactivity to social stress, reactivity to failure and prolonged reactivity had good fit to data in the Iranian sample. Correlational analyses between different dimensions of PSRS with emotional adjustment provided initial evidence for the PSRS convergent validity. Cronbach’s α Coefficients ranged from 0/75 to 0/80 for six dimensions. In sum, these findings provide evidence for the validity and reliability of the PSRS as an instrument to measure of stress reactivity among Iranian university students.

Context: One of ways to prevent mental and behavioral problems, improving psychological capital is composed of four structures hope, optimism, resilience and self-efficacy. Aim: This study aims to construct and validate the scale of psychological capital for public Areas use and its relation to psychological well-being. Method: The research method is correlation, with the statistical population composed of all married people in Tehran, out of whom 520 individuals were selected using the multistep method. The employed scales include the researcher-developed 66-item scale, Luthans 24-item Scale of Psychological Capital (2007), and Ryff psychological Well-being 18-Item Short Form (1995). For the purpose of data analyses, IRT and first- and second-order confirmatory factor analysis were adopted. In order to carry out IRT, the hypotheses of one-dimensionality and local independence were tested and measured by means of VSS, MAP and exploratory factor analysis. Then, five factors namely hopefulness, self efficacy, positive optimism, negative optimism, and resiliency were extracted by means of the first-order confirmatory factor analysis and model fit. In order to investigate whether these five factors were derived from a larger factor, i.e. psychological capital, or not, the second-order factor analysis was used. In order to measure the reliability, internal consistency was adopted as Cronbach's alpha and theta ordinal. Results: As a result of such analyses, the researcher-developed 66-item questionnaire was changed to the 44-item scale. the scale had highly and acceptably reliability coefficient (Cronbach's alpha = 0.945 and theta = 0.952) and Measuring convergent validity، the foregoing questionnaire is in positive، significant relation to Luthans Scale and Furthermore, a positive, significant relation was found between psychological well-being scale and its corresponding six factors. Conclusion: The results suggest that the researcher-developed scale is adequately reliable and valid for the purpose of measuring this construct in various social areas and fields.

Introduction: Researchers describe anxiety as a negative emotional state of restlessness, agitation, worry and somatic activation or arousal. Purpose: The aim of this study was to examination psychometric properties of the Persian version of the Revised Competitive State Anxiety Inventory-2 in athletes. Method: population of this study was whole of the Tehran's athletes. 376 questionnaires were completed by 16-44 years old athletes who took part in different fields. To assess of the inventory's construct validity, the exploratory factor analysis (EFA) is used in order to determine count of the factors, and the confirmatory factor analysis (CFA) is used in order to befit the measurement models. The inventory's reliability is calculated by using of the internal consistency method. To assess of time reliability by using of test-retest method, correlation coefficient was used. Data were analyzed by SPSS and LISREL software's. Results: The findings of this study showed that the Persian version of the inventory supports main structure, thus validity and reliability of this inventory is confirmed. Conclusion: anxiety is a factor can influence on sport performance of athletes, therefore, according to the results of this study, recommended that the Persian version of the revised competitive state anxiety inventory -2 be used to consider state anxiety of athletes.

Backgrounds: Post-event processing involves rumination about perceived inadequacy in a past social situation and has been proposed as an important maintaining factor in social phobia. Aims: This paper investigated the psychometric properties of Post Event Processing Questionnaire (PEPQ) in a student sample. Method: Participants were 460 people (280 female, 180 male) who answered the PEPQ, and 284 of the subjects (198 female and 86 male) completed four Social anxiety related questionnaires including SPAI, SAFE, LSAS-SR and SPS in addition to PEPQ. Also, fifty-five Social Phobic patients answered the PEPQ. The Pearson correlation, Independent sample t-test, Cronbach Alpha and Confirmatory Factor Analysis (CFA) is used as the data analysis method. Results: The Pearson correlation between the PEPQ and the Criteria Scales and between the test and re-test PEPQ score was significant. The CFA replicated the one factor solution for the PEPQ. The Independent sample t-test showed significant difference in PEPQ score between social anxiety group and control group. Also, internal consistency of the PEPQ was acceptable. Comparing with people with self-perspective, participants with observer perspective had a higher score in PEPQ, state anxiety, SPAI, LSAS-SR, SAFE and SPS. Conclusion: Thereupon, it seems the PEPQ is a reliable instrument for assessment of the Post Event processing in Iranian population.

This article presents a discourse analysis method designed to study networked cognitive communication processes in knowledge communities, such as conceptual change, higher order learning and knowledge building in synchronous and asynchronous mode of online learning. Object: The method is grounded on the meaning of critical thinking and the process of meaning construction in the group to reveal the basis of collaborative critical thinking through using discussion and leading to discussion in synchronous and asynchronous mode. Method: on the basis of longitude method of research and through 2 semesters (on 42 students) the implication of Socratic Questioning Prompt (SQP) are validated It was needed to prepare the teacher to have revised on the construction of meaning in the subject to design the process of reconstruction during discussion. Finding: Relations among the skills leaded to Ct promotion as an indicator considered in California Critical Thinking Test are estimated and approved in the paper. Conclusion: It is revealed that there are relations among the mentioned skills and a process which designed in online environment to promote critical thinking ability is approachable through Socratic Questioning Prompt.

Purpose: The present research is conducted aiming at studying the psychometric characteristics of sense of belonging to school questionnaire by Bree, Bethy, and Wath (2005) among Persian students.Method: The method applied in this research is descriptive-measuring and the population under study includes all male and female secondary students. The sample under study included 350 students (200 boys and 150 girls) which were selected through cluster random sampling. Data for this research was collected through different questionnaires that included school connection feeling, academic burnout, and achievement motivation. All Data were analyzed utilizing Cronbach's alpha, Exploratory factor analysis, and correlation coefficient.Findings: The total Cronbach's alpha scale is calculated 88% that indicates optimal reliability. The correlation of this scale is calculated with academic burnout questionnaire in order to determine divergent validity (-0/567) that also indicated meaningful and negative correlation. Additionally, the sense of belonging to school, and achievement motivation scale is 44% that corroborates concurrent validity of sense belonging to school connection scale. The results of exploratory factor analysis expressed six factors that included: teacher’s support, engagement in the broader community, the sense of observing fairness and respect, positive feelings to school, relationship with school, academic engagment. Conclusion: measuring the sense of belonging to school scale can be applied as reliable and valid tool in educational and research situations.
