This study delves into the determinants of emotional control among 6606 Singaporean students, aged 15 years old, participating in the Programme for International Student Assessment (PISA) 2022. It aims to explore the various factors contributing to emotional control, utilizing multiple regression analysis on data from PISA's comprehensive 2022 dataset. This research seeks to identify and analyze key contributors to emotional control among these high-performing students. Using R programming, the study entailed both descriptive and multiple regression analyses, with special attention to weighting within this large-scale, complex survey. The findings reveal the multifaceted nature of factors influencing emotional control. Key positive influences identified include stress resistance and perseverance, while empathy and a sense of belonging also play significant, albeit less dominant, roles. An interesting observation is the slight inverse relationship between assertiveness and emotional control, suggesting a complex interplay of this trait with resilience. The model demonstrates moderate explanatory power, explaining about 31% of the variation in emotional control. The insights from this study carry significant implications for holistic education, targeted interventions, and curriculum development. By shedding light on the dynamics of emotional control in high-achieving students, this research can guide the formulation of more effective and empathetic educational strategies.
