Research shows that school-aged children with higher levels of Advanced Theory of Mind (AToM) perceive a better quality of life, use more adaptive coping strategies, and exhibit greater resilience than children with lower levels of AToM. This study explored the relationships among these constructs in 332 fourth- and fifth-grade children (M = 10 years, SD = 7 months) based in north-eastern Italy, using self-report questionnaires. Results showed that higher AToM was linked to greater quality of life and resilience, and to lower use of trivializing and externalizing coping. Mediation analyses revealed that resilience and externalizing coping fully mediated the AToM–quality of life relationship. Findings underscore the value of fostering theory of mind, resilience, and adaptive coping to support children’s well-being.
