This study investigates the relationships between emotional and adversity quotient and their impact on adaptive performance, with self-leadership examined as a mediating variable. Although there is a growing body of research on emotional intelligence, adversity quotient, and adaptive performance, limited studies have specifically explored the interrelationship of these three variables within the context of elementary school teachers, particularly in rural or semi-rural regions such as Kepahiang Regency in Indonesia. This research employed a quantitative method conducted in Kepahiang Regency, involving a total sample of 230 elementary school teachers who participated voluntarily. Data collection was conducted online, using a structured questionnaire distributed via Google Forms. The analysis followed the data analysis stages outlined by Neuman, utilizing SPSS to describe respondent characteristics, and Partial Least Squares - Structural Equation Modeling (PLS-SEM) to assess indicators and test hypotheses. The results indicate that both emotional quotient and adversity quotient have a positive and significant effect on teachers' adaptive performance. Furthermore, self-leadership was found to significantly mediate the relationship between emotional and adversity quotient and adaptive performance. These findings provide important insights and contribute to the development of capacity-building programs, improvements in working conditions, and policies or initiatives that aim to enhance teaching quality and teachers’ well-being—particularly by strengthening teachers’ adaptive capacity through improved emotional intelligence, mental resilience, and self-leadership skills. This study also implies that the success of teacher adaptation is not solely determined by professional competence, but also by psychological factors such as emotional intelligence and the ability to lead oneself.Keywords: Emotional Quotient; Adversity Quotient; Self-Leadership; Adaptive Performance.
