An Explorative RVA of the Motor Development of Children With DCD <2y

Study Overview
=================
Brief Summary
-----------------
This study compares motor development in three groups of infants (controls, DCD, DCD+ASD) before the age of 2 years using retrospective video analysis of infants in home video contexts.

Official Title
-----------------
An Explorative Retrospective Video-analysis of the Motor Development of Children With Developmental Coordination Disorder Before the Age of Two

Conditions
-----------------
Developmental Coordination Disorder, Autism Spectrum Disorder

Intervention / Treatment
-----------------
* Diagnostic Test: Movement Assessment Battery for Children 2(M-ABC-2)
* Diagnostic Test: Developmental Coordination Disorder - Questionnaire (DCD-Q)
* Diagnostic Test: Social Responsiveness Scale 2 (SRS-2)
* Other: Retrospective Video Analysis

Eligibility Criteria
-----------------

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Controls<br>This groups consists of children now aged 6-12y: Without a medical diagnosis possibly influencing motor development Without motor problems (M-ABC-2 and DCD-Q) Without social reponsiveness problems (SRS-2) | Diagnostic Test: Movement Assessment Battery for Children 2(M-ABC-2)<br>* The M-ABC-2 is a motor performance test for children aged 3 trough 16 years of age. We will use Dutch-Flemish norms.<br>Diagnostic Test: Developmental Coordination Disorder - Questionnaire (DCD-Q)<br>* The DCD-Q is a brief parent questionnaire designed to screen for the presence of DCD in children aged 5 trough 15 years of age. We will use Dutch norms.<br>Diagnostic Test: Social Responsiveness Scale 2 (SRS-2)<br>* The SRS-2 is a parent questionnaire designed to identify social impairments associated with ASD in children 4 trough 18 years of age. We will used Dutch norms.<br>Other: Retrospective Video Analysis<br>* Retrospective video analysis will be used to explore motor development in children with DCD, DCD+ASD and controls.<br>|
