Peer problems mediate the relationship between developmental coordination disorder and behavioral problems in school-aged children.
Motor problems in DCD hurt kids through social rejection, not just poor coordination.
01Research in Context
What this study did
Oliver and team studied 8-11 year olds with developmental coordination disorder (DCD).
They asked: Do peer problems explain why these kids later show behavior issues?
The team used surveys and teacher reports to map the pathway from motor problems to peer rejection to emotional outbursts.
What they found
Kids with DCD who got rejected by peers showed more anger, sadness, and rule-breaking.
The data suggest peer rejection acts like a bridge between clumsy movements and later behavior problems.
But the study was cross-sectional, so we can't say which came first.
How this fits with other research
Peng et al. (2026) shows exercise fixes motor skills in DCD. This matters because Oliver's work hints fixing motor skills might also protect kids from peer rejection.
de Graaf et al. (2011) found motor problems link to anxiety and depression using twins. Their genetic control strengthens Oliver's story that motor issues create real social pain, not just shared family traits.
Ben-Itzchak et al. (2020) discovered DCD kids learn new motor tasks but can't transfer them. This helps explain why Oliver's kids keep struggling in real play situations, feeding the peer rejection cycle.
Why it matters
When you see a child with DCD, don't just track their motor goals. Ask their teacher: 'Who plays with them at recess?' One rejected child might need social skills training more than extra balance practice.

03Original abstract
The aim of this study was to gain insights into the relationship between developmental coordination disorder, peer problems, and behavioral problems in school-aged children where both internalizing and externalizing behavioral problems were considered. We assumed that the relationship between developmental coordination disorder and internalizing/externalizing problems in school-aged children is mediated by peer problems and tested the hypothesis that a greater degree of motor impairment causes a greater degree of peer problems and thus a greater degree of internalizing or externalizing problems. Seventy boys and girls aged between 5 and 11 years were examined using the Movement Assessment Battery for Children 2 and the Intelligence and Developmental Scales. The results of path analysis showed that the relationship between developmental coordination disorder and internalizing/externalizing problems in school-aged children is mediated at least in part by peer problems. However, the cross-sectional design of the study does not provide conclusive evidence for a cause-effect relationship and only allows for the conservative prognosis that a greater degree of motor impairment may cause a greater degree of peer problems and thus a greater degree of internalizing/externalizing problems. Nevertheless, the results of this study emphasize the importance of being well-integrated in their peer group especially for children with developmental coordination disorder.
