Regional endogenous development can be reached through the interaction of regional entrepreneurship along with other variables such as leadership, institutions, market-fit and resource endowment. In this way, regional entrepreneurship is one of the mediating variables of endogenous regional development and can facilitate the process of achieving development like a catalyst. The purpose of this study is to investigate the relationship between these factors in endogenous development through analyzing statistics related to case study. Therefore, after determining some criteria and indicators related to main variables of regional entrepreneurship (human capital and new knowledge) from various sources, the existing relationships between the indicators with each other, indicators with variables and independent and mediating variables with dependent variable will be analyzed by using methods such as PLS method and structural equations and relying on available and collected statistical data. Since in the research measurement model, the factor loadings between each of the variables and their indicators are more than 0.4 and also the Cronbach's alpha coefficient and the combined reliability coefficient of each of the variables are more than 0.7, as a result, the reliability of the research model is acceptable. Also the average extracted variance of all variables is greater than 0.5, as a result, the convergent validity of the model is also within the acceptable range; On the other hand, the values on the main diameter of the Fornell and Larcker matrix are larger than all the values in the corresponding column. Therefore, it can be concluded that this model has acceptable divergent validity. the structural model of the research shows a regression coefficient of 0.698 between the two variables of entrepreneurship and regional endogenous development at a significance level of less than 5%, which proves the relationship between these two variables and as a result the research hypothesis at an acceptable significance level. At the end of the research and by proving the mediator role of entrepreneurship in the process of regional endogenous development, the development level of all the Tehran counties has been shown based on the research data and statistics, and then policies and action plans aimed at improving the development level of less developed counties based on entrepreneurship have been suggested.

Scientific research includes philosophical, procedural, and ethical steps, and studies with a positivist philosophical premise, which show the recent meta-method reviews, still include a share of more than 70% of studies in humanities and social sciences. From a comparative point of view, it dictates a quantitative approach to researchers. In this approach, entering the field of measurement and then discussing the identification of metrics and linking them with variables or at a more abstract level with structures is, if not the most important, one of the most prominent cases. The vagueness and conceptual immanence of these structures in these sciences makes it more and more difficult for researchers to fully realize validity and reliability. With a scientific review and in a narrative format, focusing on the reliability aspect and the generalizability aspect of the results, the researcher enumerates the weak but unfortunately very common indicators in Iran research literature. Then, with an evaluative and pathological point of view, it proposes a suitable solution to overcome this procedural structural weakness by analyzing and introducing a suitable and operational alternative for it, i.e. McDonald's Omega Coefficient. It was estimated that the results of the present study will create a stable and satisfying perspective in changing the viewpoint of researchers in related humanities fields.

The aim of this study was to validation of the Persian version of the scale of enjoyment of physical activity in first grade high school students in Khuzestan province.

Among all of high school students in Khuzestan province who were studying in the academic year 1399-1398, 382 were clustered randomly selected (199 boys and 183 girls). The research tool was the scale of enjoyment of physical activity, the validity and reliability of which were also confirmed. The implementation method was such that using the open translation method, the translation accuracy of the Persian version of the scale was confirmed. For data analysis, confirmatory factor analysis was used to validate the structure and internal consistency using Cronbach's alpha coefficient at a significance level of p≤0.05.

The results of confirmatory factor analysis of physical activity enjoyment scale indicators indicate that the measurement model has a favorable fit and all physical fitness subscales of physical activity enjoyment index had an acceptable factor load and were confirmed. The internal consistency was 0.90 and the internal consistency of the pleasure subscale was 0.82%, communication was 0.78%, competency was 0.72%, improvement was 0.70% and entertainment was 0.74%. It came in handy.

Therefore, the Persian version of the scale of enjoyment of physical activity had structural validity and internal reliability and can be used as a valid and stable tool among students.
