This research was conducted using the meta-analysis method with the aim of synthesizing existing research on the relationship between identity styles and academic performance. The statistical population of the study included all relevant studies conducted in Iran from 1385-1400 and available in the databases of Jahad Daneshgahi, Nurmagz, and Magiran. After evaluating the criteria for entrances and layaway requirements research, the correlation effects of the research were analyzed by CMA software. Also, two models of random effect and fixed effect were calculated. According to the results of the heterogeneous analysis, the randomized model was selected through Q and squared I indices. The findings revealed that the size of the combined effect of the investigated research after the removal of 4 effects size was 0.107. The combined effect size of the research was calculated based on the mean Cohen’s index. The results of heterogeneous analysis revealed of the existence moderating variables in the research as well. The results of this meta-analysis of theoretical and empirical foundations are indicative of the relationship between identity style and academic performance variables. Given the results of this meta-analysis, it can be concluded that for academic performance to be successful, it is essential to address the identity style among university and school students.

Meta-analysis of the effectiveness of sex education on psychological variablesThis research was carried out to investigate Quantitative results of experimental studies conducted on the effect of sex education on parents and children using meta-analysis method between 1394-1400 in Iran. The statistical population is all studies related to sexual education that have been published in scientific research journals, Among them, 10 studies that were methodologically acceptable were selected and meta-analyzed. The research tool was a meta-analysis checklist and Cohen's effect size method was used to obtain the overall relation value. Data analysis was performed with version 2 of CMA software. The results showed that the average size of the effects is 1.17 which is a high effect size. It is included that sex education has had a significant effect on the psychological variables used in the studies. However, new research in this area seems necessary.Keywords: Meta-analysis، sex education، psychological variables

Purpose: The purpose of this research was to construct and validate the wisdom test based on Iranian components. Method: In this research, a mixed (qualitative-quantitative) method of exploration plan was used. In the first stage (qualitative), a semi-structured interview was carried out with 20 faculty members of Hamadan University of the Humanities (a qualitative research method of phenomenological type). Sampling method was purposeful and based on theoretical saturation. The content analysis method was used to analyze the interview data. In the second stage (quantitative), based on the coding and compilation of the content of the information obtained from the interviews, a questionnaire of 40 questions was formulated. Then, based on multi-stage cluster sampling, 400 people (281 women and 119 men) participated in the study. At this stage, a confirmatory factor analysis method was used to analyze the data (Bartlett and KMO tests and gravel charts). In order to investigate the validity of construct wisdom test, the internal correlation coefficient of the questionnaire and the correlation coefficient of this test with the Ardelt test, were used for content validity of the crest test using Cronbach's alpha coefficient and two-way semi-test and for the reliability of the test, test-retest method was used. Results: The results of content analysis in the first stage (qualitative) showed that wisdom has four components: 1- cognitive component 2- emotional component 3- component of "flexibility and openness to experience" 4- component "Self-transcendence / targeting and searching for meaning." Also, the results of factor analysis (stage II) showed four factors; the first factor (including questions 2-3-4-5-6-8-10-14-15-20-21-32-40) entitled " Emotional dimension ", the second factor (including questions 1-7-9-12-13-16-17-19-22-23-24-25-29-30) entitled" Cognitive dimension ", the third factor (including questions 26 -27-28-35-36-38) as "Dimensional Flexibility" and the fourth factor (including questions 11-18-31-33-34-37-39) entitled "After Self-Processing".

Background: transition to adolescence is accompanied with rapid changes, unexpected and new cognitive, social, emotional and psychological experiences that makes challenges for adolescents and are considered as underlying factors of stress. Aim: The aim of present study was examining the psychometric properties of the Iranian version of Adolescent Stress Questionnaire (ASQ) in high school students of both genders. Method: The study sample consisted of high school students in Hamadan city in 2015 school year. 280 students were selected based on multi-stage random sampling. To study psychometric characteristics of the questionnaire, Adolescent Stress Questionnaire was translated with double-translation technique and finally, to evaluate the psychometric properties of the questionnaire, it was administered along with depression, anxiety, stress scale (DASS) and state anxiety Inventory (SAI) of Spielberg. Collected data was analyzed and reliability and validity indicators and confirmatory factor analysis were calculated. Results: Analysis of the collected data showed that the questionnaire has the reliability of 0.75 to 0.85 alpha coefficients in ten subscales, In addition, the concurrent validity of the questionnaire with subscales of depression anxiety, stress scale and trait anxiety questionnaire was equal to 0.34, 0.35, 0.82 and 0.15 respectively which in the p

Introduction:various studies have shown the relationship between religious orientation and mental health and physical health .meta-analysis ith integrating results from various researches,specifies Relationship between the variables.this Research is intended to use the meta-analytic model to examine the relevance of mental health to religious orientation. Methods: We reviewed records of all research related to the relationship between religious orientation and mental health in the Journal of Research Persian have been published 10 research that were accepted in methodological procedure selected and meta-analysis was done. Research tool was the Czech List of meta analysis and Cohen's effect size method was used to achieve the overall relationshipResults: the results showed that The effect size of relationship between religious orientation and mental health equal to 428/0 was obtained and by conversion of the d value of z in normal distribution curve according to the Cohen's criteria is a high value.Conclusion: Considering the high relationship between religious orientation and mental health programs we can develop an adequate programs toan individual's religious orientation towards health promotion and treatment.
