The effect of work-family conflict on the performance of physical education teachers with the role of mediator and moderator of work stress

The purpose of this study is to investigate the effect of work-family conflict on the performance of physical education teachers in Semnan province with the role of mediator and moderator of job stress. This study is applied in terms of purpose, descriptive-correlational in terms of method, cross-sectional in terms of time, and survey in terms of data collection method. In terms of design, it is non-experimental and correlational in terms of structural equation modeling. The statistical population of this study included all physical education teachers in Semnan province in the academic year 2023-2024 (300 people). The sample size was estimated according to Kline's theory (2014) and the number of items was between 100 and 400 people. The data collection tools are Saragih 's job stress questionnaire (2011), Buil et al.'s job performance (2019), and Netenmeyer et al.'s family-work and work-family conflict (1996). The distribution of the questionnaires was accessible. SPSS and Smart-PLS 4 statistical software were also used to analyze the data. The findings showed that work-family conflict has a negative and significant effect on the job performance of physical education teachers in Semnan province with the moderating role of job stress, and job stress has a mediating role in the relationship between family-work conflict and job performance, meaning that part of the effect of family-work conflict on job performance depends on the presence of the job stress variable. These results emphasize the need for multi-level interventions to break this vicious cycle.
