Personality traits are one of the most important factors in preserving and disintegrating the family. People who have adaptive behaviors and can manage their unpleasant and negative emotions experience better relationships. Therefore, it is necessary to investigate the role of psychological factors in the quality of couples' relationships.

The present study aimed to investigate the relationship between character strengths and marital relationship quality using structural equation modeling, with integrative self-knowlege as a mediator.

The current descriptive and correlational research was conducted using structural equation modeling. The statistical population of this research consisted of all married men and women living in Tehran in 1402. The sample was 392 people who were randomly selected in a multi-stage cluster. In order to collect data, questionnaires of the quality of couple relationships were used by Kundi et al. (2016), Patterson and Sigelman's character abilities (2004), Ghorbani et al.'s (2008) cohesive self-knowledge. In order to evaluate the proposed model, structural equation modeling was used using AMOS and SPSS-27.

The results indicated that the structural model of the relationship between character strengths and marital relationship quality with integrative self-knowlege as a mediator fit the data well. Both character strengths and integrative self-knowledge were found to have direct and positive effects on marital relationship quality. Additionally, character strengths indirectly influenced marital relationship quality through integrative self-knowledge (β= 0.174, P< 0.001). These findings suggest that enhancing character strengths, both directly and indirectly through the influence of integrative self-knowlege, can play a significant role in improving marital relationship quality.

The findings of the present study contribute to a clearer understanding of the concept, dimensions, and factors influencing marital relationship quality. This knowledge can serve as a basis for strategic decision-making aimed at strengthening families. Moreover, the study can lead to a deeper understanding of the concept of marital relationship quality and complement existing theories in this field.

Marital conflict is an interactive process in which couples feel uncomfortable about aspects of their relationship and sometimes try to resolve it in different ways. The aim of this study was to determine the appropriateness of structural equation modeling of early maladaptive schemas and marital conflicts with the mediating role of alexithymia. This research is applied and in terms of methodology, is the descriptive of correlation between structural equations. The statistical population of this study included all married people who referred to the psychological clinics of Tehran's District 2 in the period from February 2016 to July 2017, which is at least one year after their married life. In order to sample 300 people from the mentioned community, they were randomly selected by voluntary sampling method. Data collection questionnaires Marital conflict questionnaire (Sanai, Barati and Boostanipoor, 1996), Yang's early maladaptive schemas (Young & Brown,2005), and Toronto's Emotional Disappointment (Bagby, Taylor & Parker, 1994) were used to collect data. The data were collected using statistical method of structural equation modeling (SEM) using AMOS_22 software. The results showed that the fit indicators after model modification have property values and are in good fit with the research model and also the scope of early maladaptive schemas is related to the mediating role of questionnaires with marital conflicts. The result is that existing relationships can be used to improve marital relationships.

The present study was conducted with the aim of examining the causal-structural relationships of self-efficacy and self-regulation with Internet addiction, with the mediation of quality of life among teenagers in Tehran.

The research design is descriptive-retrospective correlation. A total of 314 teenagers were selected from the teenagers of Tehran city using available sampling method. The data were collected using Young's Internet Addiction Questionnaire, Warosherbon's 36-item Quality of Life Questionnaire, Beaufard's Self-Regulation Questionnaire, and the Self-Efficacy Questionnaire of Mauritian Children and Adolescents. The data were analyzed using the structural equation modeling method in AMOS-Graphic software version 24.

All research variables except self-regulation had a significant negative relationship with Internet addiction. The path coefficients indicated the appropriate fit of the model in which both quality of life (directly) and self-efficacy (indirectly through quality of life) predicted Internet addiction. The direct paths of quality of life with Internet addiction, self-regulation with self-efficacy are significant at the level of significance (α<0.01) and self-efficacy with quality of life are significant at the level of significance (α<0.05). The results for the direct paths of self-efficacy with Internet addiction, self-regulation with Internet addiction and self-regulation with quality of life were not significant (α>05). Also, the indirect effect of self-efficacy on Internet addiction through the mediation of quality of life was confirmed (α<0.05) and the indirect effect of self-regulation on Internet addiction through the mediation of quality of life was rejected (α>0.05). Conclusion Quality of life and self-efficacy play a key role.

As a result of the changes and developments in technology, the phenomenon of education has also gone out of its traditional form and has appeared in the form of distance education or electronic education.

Structural Equation Modeling (SEM) is a very general statistical modeling technique, which is widely used in the behavioral sciences. It can be viewed as a combination of path analysis, regression and factor analysis. One of the prominent features of this method is the ability to compute direct, indirect and total effects, as well as latent variable modeling.

This systematic review study done on published original article in Iranian search database (Iranmedex, SID, Magiran) and international search database (Google Scholar, ISI, Scopus, Science Direct ، Pubmed) during year 1973 until 2018. In this study searched done with key words like " Correlation", " Path Analysis", " Factor Analysis: Confirmatory And Explanatory", " Structural Equation Modeling: SEM", " Latent variable", " Formative Model", " Reflective Model", "Multiple Indicators Multiple Causes: MIMIC", " Direct Effect", " Indirect Effect" and " Total Effect" and related Persian synonyms.

The review of articles contain structural equation modeling shows the new study areas like formative versus reflective structural models, Multiple Indicators Multiple Causes: MIMIC model, variance versus covariance model, structural models with non-normal response and use item response model for analyzing latent variables.

The aim of the present study is to investigate the relationship between conscientiousness and professional qualifications of teachers. The research was descriptive and correlational in nature. The population included all school teachers in secondary schools of the city of Marivan with 610 (N=610) in 2015-2016 academic year. 235 teachers were selected through stratified sampling. The instruments were three standard questionnaires of professional competencies of teachers, conscientiousness of NEO and effectiveness of teacher’s assessment that was a researcher-made questionnaire. The reliability of questionnaires, using Cronbach's alpha coefficient for the professional competencies of teachers was 0.94, conscientiousness of NEO was 0.82, and the effectiveness of teacher’s assessment was calculated to be 0.88. The results revealed that professional competencies can predict teachers' efficacy per se, but mere conscientiousness cannot predict teachers' efficacy, however, it can do so by the mediating role of professional competency. Also, findings confirmed that conscientiousness had little power in predicting teachers' efficacy, while professional competencies had more power in predicting teachers' efficacy.

The aim of this study was to evaluate the psychometric properties of the cognitive emotion regulation questionn aire in university students.The data were collected from Islamic Azad University, Central Branch in Tehran in the form of cluster sampling. A sample including 360 individuals responded to the Persian version of cognitive emotion regulation questionnaire. Confirmatory factor analysis was used to check the validity. In confirmatory factorial analysis of the cognitive emotion regulation questionnaire using Amos 21, 10 questions were eliminated, culminating in a 26-item questionnaire with seven factors, confirming the theoretical background. The measurement model enjoyed a favorable fitting. Cronbach's alpha was used to check the reliability, which was obtained as 0.812for the 26-item questionnaire. Since the cognitive emotion regulation scale (26 items) enjoyed a good reliability and validity, thus it can be used in diagnostic and research areas
