A Dimensional Approach to Comorbidity Between Developmental Coordination Disorder and Dyslexia: A Study of Graphomotor Abilities

Approche dimensionnelle de la comorbidité entre trouble développemental de la coordination et trouble spécifique de l’apprentissage de la lecture : étude sur la graphomotricité

Abstract

The present study examined the comorbidity between developmental coordination disorder and dyslexia, adopting a dimensional approach. Participants were 120 children aged 8 12 years, with or without developmental disorders. After assessment with a reading test (Alouette) and motor test (MABC), children performed handwriting and graphomotor tasks on a graphic tablet. GAM analyses were used to test the contribution of the children’s reading and motor test scores to their handwriting and graphomotor performances. Results revealed a correlation between reading and motor scores, despite considerable heterogeneity within the groups. The variables measured during the handwriting and graphomotor tasks often depended on the children's scores on the motor and reading tests. Results support the hypothesis of shared risk factors for DCD and dyslexia, and confirm the relevance of adopting a dimensional approach to neurodevelopmental disorders.
