This study aims to find the relationship among sports education, psychological well-being, social development, strategic capacity, and environmental awareness in China. Moreover, the mediating role of psychological well-being and strategic capacity is also explored. Data were collected from 869 Chinese individuals using a structured questionnaire based on previously validated Likert-scale instruments measuring six constructs: sports education, psychological well-being, social development, cognitive focus, strategic capacity, and environmental awareness.
