The aim of the study is to investigate theory of mind (ToM) in children with developmental coordination disorder (DCD). Dutch-speaking children, who are living in Flanders or The Netherlands (because comparisons will be made with Flemish and Dutch norms), will be included. In addition, children should be six until twelve years old with a DCD diagnosis confirmed by a multidisciplinary team (including a doctor).

During the test moment, ToM will be tested by ToM test-R and the motor skills by MABC-2. Beside, the ToM test-R will be filmed, but the child's face not shown. The parent/legal guardian will be asked to complete five online questionnaires (demographic and developmental questionnaire, CVO, SRS-2, SDQ and ToMBC), this can be completed in advance at home or at the test moment (researchers provide a laptop).

Inclusion Criteria:

• Age of child: from six to 12 years old
• Confirmed diagnosis of DCD by a multidisciplinary team (including a physician)
• Child lives in Flanders or the Netherlands
• Child has Dutch as the mother tongue

Exclusion Criteria:

• Diagnosis of autism spectrum disorder (ASD)
