Abstract
The Environmental Stress Hypothesis (ESH) illustrates the underlying mechanisms of internalizing problems in children with Developmental Coordination Disorder (DCD), indicating that the relationship between DCD and internalizing problems could be influenced by numerous physical and psychosocial consequences. However, the potential pathways described in this conceptual framework have not been comprehensively examined. Furthermore, given that child development is a dynamic process, these pathways have not been investigated from a developmental perspective. In order to address these gaps in knowledge, this dissertation sought to advance our understanding of the ESH by examining the underlying mediating pathways connecting DCD and internalizing problems in three age groups: early childhood, late childhood/early adolescence, and young adulthood. \n Study 1 showed that preschool children at risk for DCD (rDCD) experience more internalizing problems than typically developing children. However, physical activity and BMI do not mediate the relationship between rDCD and internalizing problems. Overall, our findings confirm that rDCD and internalizing problems co-occur in early childhood. Nevertheless, as there is no mediation of physical activity or BMI, the underlying mechanisms may be more related to other psychosocial outcomes (e.g., self-concept or perceived social support), suggested in the ESH. \n Study 2 examined school-aged children and included global self-worth, one of the psychological outcomes identified in the ESH, to address one of the limitations in Study 1. Findings support the ESH by showing a sequential mediating pathway from probable DCD (pDCD), through physical activity/BMI and global self-worth, to self-reported internalizing problems. Sex was found to moderate the underlying mechanisms of internalizing problems, altering the pathways from pDCD to internalizing problems. \n Study 3 was conducted to test the full ESH in emerging adults. Results support the mediating effects of psychosocial well-being, including stress, global relationships, perceived social support, and self-concept, on the relationship between poor motor coordination and self-reported psychological distress in young adults. However, in this age group, physical inactivity and higher BMI, did not mediate the relationship between motor coordination and internalizing problems. \n In conclusion, this dissertation highlights the co-occurrence of motor difficulties and internalizing problems across three developmental stages. The underlying mechanisms of internalizing problems may differ by age and sex. It is also worth noting that compared to physical health, psychosocial well-being may play a more important role as a mediator in the relationship between motor coordination and internalizing problems.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
