Given the severe psychological stress of teachers in educational settings, it is of particular value to pay attention to improving their psychological well-being and to identify the factors that contribute to the decrease or increase in teachers' psychological well-being. For this reason, the aim of the present study was to investigate the role of predictor variables of psychological resilience, happiness, and mindfulness in the criterion variable of teachers' psychological well-being. For this reason, 113 people were selected from the statistical population of elementary school teachers in Rasht in the academic year (2023-2024) using the convenience sampling method and responded to the questionnaires of psychological well-being (Reif and Keyes, 1995), psychological resilience (Connor and Davidson, 2003), Oxford Happiness (Hills and Argyle, 2002), and Freiburg Mindfulness (Wallach et al., 2006). The results were analyzed in SPSS22 software using Pearson's correlation coefficient and stepwise regression, and the results showed that the relationship between psychological resilience and psychological well-being (r=0.61), the relationship between happiness and psychological well-being (r=0.49), and the relationship between mindfulness and psychological well-being (r=0.41) was positive and significant (p<0.01), and the three variables explained 50% of the variance in the changes in teachers' psychological well-being. Therefore, the psychological well-being of elementary school teachers can be predicted based on psychological resilience, mindfulness, and happiness.

The purpose of the research is to analyze the effects of ethical leadership and organizational politics on individual and team creativity, focusing on the mediating role of knowledge hiding. The study is a descriptive-correlational survey and is applied in terms of purpose. The statistical population included employees of selected public organizations in the Eqlid County, totaling 950 individuals. 270 individuals were selected using a non-probability convenience sampling method based on the rule of thumb for SEM as the sample. To collect data, the following measures were used: Brown's et al. (2005) Ethical Leadership scale, the Organizational Politics scale by Kacmar and Carlson (1997), the Knowledge Hiding scale by Serenko and Bontis (2016), the Individual Creativity scale by Zhou and George (2001), and the Hanke's (2006) Team Creativity scale. The validity of scales was confirmed using the content validity, and the reliability was examined using Cronbach's alpha, yielding values of 0.89 for the Ethical Leadership, 0.82 for the Organizational Politics, 0.92 for the Knowledge Hiding, 0.87 for the Individual Creativity, and 0.85 for the Team Creativity. For data analysis, SEM and the AMOS software were used. The results of the study fitted the research model, indicating that ethical leadership and organizational politics have a significant negative impact on knowledge hiding. Additionally, knowledge hiding has a significant negative effect on both individual and team creativity of employees. By reducing knowledge hiding behaviors through ethical leadership and organizational politics, the level of creativity among employees at both individual and team levels increases.
