title: Evaluation of the psychometric properties of the developmental coordination disorder questionnaire for parents (DCD-Q): results from a community based study of school-aged children.
abstract: In this study, we examine several key psychometric properties (reliability, construct validity, concurrent validity) of the Developmental Coordination Disorder Questionnaire (DCD-Q) using a large, school-based sample of children (n=523) and their parents. Children completed the Children's Self-perceptions of Adequacy in and Predilection toward Physical Activity (CSAPPA) and parents completed the DCD-Q. The internal reliability of the DCD-Q was high for both the full scale and the subscales. Confirmatory factor analysis established that the scale was multifactorial, but the fit of the hypothesized factor structure was poor. Finally, moderate correlations were observed between the CSAPPA and the DCD-Q, with the strongest correlation found between the "perceived adequacy" subscale of the CSAPPA and "control during movement" subscale of the DCD-Q. Implications for screening and further research are discussed in relation to both instruments.
