title: Reliability and validity of a parent questionnaire on childhood motor skills.
abstract: OBJECTIVE
  As the consequences of clumsiness in children become better understood, the need for valid measurement tools is apparent. Parent report has the potential for providing historical knowledge of the child's motor skills, as well as perceptions of their children's motor difficulties. The objective was to develop a parent questionnaire to identify motor difficulties in children.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  The DCDQ is a succinct and useful measure for use by occupational therapists.
