Development and relationship of motor performance, executive functions, and scholastic achievement in children at risk for developmental coordination disorders

一项为期三年的纵向研究计划采用队列序列设计，在研究开始时检查5或6岁儿童的运动和认知发展。样本包括有发育协调障碍风险的儿童和对照组儿童。该研究的第一个目的是详细描述和分析两组儿童的运动和认知功能的发展途径，重点是在执行功能方面与标准发展的数量和/或质量偏差。第二个目的是调查两组儿童的认知和运动表现的关系和相互作用。这应该可以回答一个问题，即潜在的潜在抑制缺陷是否导致了处于危险中的儿童的认知和运动问题。第三个目的是分析运动和认知表现的纵向稳定性。这应该使我们能够回答这样一个问题：有发育协调障碍风险的儿童以后是否会赶上他们的同龄人，或者这些问题是否仍然存在。在第三个测量点，将评估儿童的学业成绩，以确定可能导致发育协调障碍风险儿童频繁出现学校问题的预测因素。

A three-year longitudinal study using a cohort-sequence design is planned to examine motor and cognitive development in children aged 5 or 6 years at the beginning of the study. The sample includes children at risk for developmental coordination disorders as well as control children. A first aim of the study concerns the detailed description and analysis of the developmental pathways of motor and cognitive functions in both groups, with a focus on quantitative and/or qualitative deviations from normative development in the area of executive functions for children at risk. A second aim is to investigate relationships and interactions of cognitive and motor performance in the two groups of children. This should allow answering the question whether a potentially underlying inhibition deficit is responsible for cognitive and motor problems of children at risk. A third aim is to analyze the longitudinal stabilities of motor and cognitive performance. This should enable us to answer the question whether children at risk for developmental coordination disorder will later catch up with their age mates, or whether the problems still persist. At the third measurement point, children´s scholastic achievement will be assessed to identify predictors which might be responsible for frequent school problems of children at risk in terms of developmental coordination disorders.
