Abstract
Objective. As the consequences of clumsiness in childrenbecome better understood, the need for valid measurement tools is apparent. Parent report has thepotential for providing historical knowledge of the child’s motor skills, as well as perceptions of their children’s motor difficulties. Theobjective was to develop a parent questionnaire to identifymotor difficulties in children. Method. A sample of 306 children participated in the development of a 17-item parent questionnaire, called the Developmental Coordination Disorder Questionnaire (DCDQ). Internal consistency, concurrent and construct validity were examined. Results. The DCDQ proved capable of distinguishing children who had motor problems (as measured by standardized tests) from children without motor problems. Correlations with standardized tests were significant. Two other studies confirmed the construct validity of the DCDQ. Factor analysis revealed four distinct factors, useful in defining the nature of the difficulties. Conclusion. The DCDQ is a succinct and useful measure for use by occupational therapists.
