This study examines the relationship between Theory of Mind (ToM) and internalizing symptoms in middle childhood and early adolescence. This developmental period has been largely neglected by ToM researchers, even though internalizing symptoms typically emerge and become stable at this age. In a sample of 318 (157 girls) school-aged children, we found that a high ToM performance is significantly associated with low depressive symptoms and low symptoms of panic disorder and separation anxiety. Further analyses revealed that problem-solving abilities mediate the relationship between ToM and depressive symptoms. Moreover, problem-solving abilities also mediate the relationship between ToM and separation anxiety symptoms, in boys only. The present findings suggest that depressive and separation anxiety symptoms in middle childhood and early adolescence might derive from a complex interaction between ToM abilities and coping strategies.
