The statistical population of the study included all high school adolescent girls in Varamin in the academic year 8931-33. The sample consisted of 93 people, who were selected by multi-stage cluster random sampling and randomly assigned to the experimental and control groups. The experimental group received life skills training in 83 sessions of 03 minutes; while the members of the control group did not receive any educational intervention. Data collection tools were SCL33 Mental Health Scale and Iranian Adolescents' Risk LARS.

The purpose of this study was a comparative study of command styles in the police of the United States of America, United Kingdom, Australia, Turkey and the Islamic Republic of Iran.

The research method is comparatively case-based. For this purpose, it focused only on the studies of the last 10 years. For this reason, several researches were extracted by reviewing the websites of the studied countries. After studying them and eliminating irrelevant or less relevant items, 38 researches (articles, dissertations or research projects) were selected and became the basis of qualitative comparative study.

Based on research conducted in the police of the studied countries, the results showed that transformational leadership styles, integrated (transformational and exchange), active leadership and role modeling, ethical leadership, participatory leadership (relationship oriented) and situational leadership with many positive organizational consequences Were in a relationship; While leadership styles of non-intervention (passive / avoidance) and authoritarianism were associated with increasing negative consequences in the organization.

Based on the total results, firstly, transformational leadership style and secondly, integrated leadership style (transformational leadership style and exchange with each other) had the most research support in terms of leading to positive.

The Navy, as part of the Army of the Islamic Republic of Iran, has a mission to be diligent in protecting the borders of strategic resources of the society by considering the extent and breadth of the country's water borders and improving the combat capability of its forces.

The coefficients obtained from the calculation of Cronbach's alpha also confirmed the reliability of the instrument.

The findings of data analysis showed that the effectiveness of skill-based training has a significant relationship with combat capability. According to the hypothesis test results, the correlation coefficient obtained 0.892 indicates a strong correlation between predictor variables (effectiveness of training based on technical skills, human skills and perceptual skills) and the dependent variable (combat capability of employees) and the coefficient of determination Adjusted to 0.793 indicates that the predictor variables were able to provide 79% of the combat capability of Nedaja officers.

Instructors of NAJA public education centers are affected by various types of stress. However, due to the high importance of the efficiency of these forces in training and educating skilled and valuable human resources, the negative effects of job stress on them can cause many harms to the NAJA. Accordingly, the present study was conducted to investigate the effect of job stress on the performance of trainers in NAJA Public Education Center.

In order to measure the research variables, two questionnaires of job stress and the questionnaire of instructors' efficiency were used. Research questionnaire indices were obtained from related studies and research background and then localized based on research conditions and study environment. The statistical population of this study was the educational instructors of Public Education Center in the summer of 8931. Due to the limited statistical population of the study, the counting method was used and the research tool was distributed among all employed educators. Validity and reliability of the research model and data analysis were performed using structural equation modeling and confirmatory factor analysis in SMART PLS software.

The research findings showed that job stress has a negative and significant effect on the efficiency of trainers and its dimensions (discipline, training techniques, motivation, communication skills and training skills) in NAJA General Education Center.

The findings of this study showed for the first time that by reducing job stress among trainers in educational centers and increasing the quality of work life, their efficiency improves and as a result, the quality of learners' education also increases..
