Abstract
As the role of primary education teachers is crucial in shaping the psychological and social conditions of the world’s future generations, it is important for teachers to be affective in their role. Their work efficacy, which depends on their psychological and mental state and their well-being, is related to subjective happiness and mental resilience being the two main determinants influencing the well-being of individuals. This quantitative study aims to investigate the levels of subjective happiness and mental resilience in primary education teachers and how these were affected after the COVID-19 pandemic. A quantitative survey questionnaire was used to analyze the factors contributing to the subjective happiness and mental resilience. The findings show that teachers with higher levels of happiness reported viewing their life and work more favorably, more positive outcomes at work, high self-satisfaction levels and greater ability to cope with challenges. Also, the study reveals that higher levels of happiness are preventing factors for the development of future psychological and mental disorders, while they have a negative correlation with disorders such as depression, and a positive correlation with mental resilience, self-perceived quality of life and flexibility in adverse situations.
