Job engagement as an attitude is an important variable that helps increase the effectiveness of the organization. This means that the higher the level of job engagement of employees in an organization, the greater the effectiveness of that organization. On the other hand, increasing mental well-being and a favorable psychological climate in the workplace increases job engagement. In this regard, the present study has examined the relationship between mental well-being and job engagement of teachers with the mediating role of psychological climate using a quantitative approach. The research is applied in terms of its purpose and descriptive nature of the correlation type based on structural equations. Research information and data have been collected by documentary and field methods, and the main tool for collecting research findings has been standard questionnaires. The statistical population of the study is all teachers of girls' high schools in District 5 of Mashhad Education in the academic year 1403-1404, with a total of 550 people, of which 225 people have been selected as the sample size based on the Cressey and Morgan table. The sampling method is cluster random. The validity of the measurement tool (questionnaire) was achieved through face and convergent validity, and the overall reliability of the research tool was 0.942 through Cronbach's alpha coefficient. To test the research hypotheses, the path coefficient and variance-affixed analysis (VAF) were used, and the model was fitted using structural equations and Smart-Pls. The research findings show that at a confidence level of 0.95, subjective well-being has a significant positive effect on job commitment and psychological climate. Psychological climate has a significant positive effect on job commitment. Psychological climate also mediates the relationship between subjective well-being and job commitment and has a minor effect.
