title: The revised DCDQ: is it a suitable screening measure for motor difficulties in adolescents?
abstract: The parent-rated Developmental Coordination Disorder Questionnaire (DCDQ) has been revised to incorporate a wider age range, including adolescence. In this exploratory study, internal consistency and validity of the DCDQ-2007 was assessed using a community-based sample of 87 adolescents. Psychometric properties of the DCDQ-2007 were investigated and concurrent validity, sensitivity, and specificity were assessed with the MABC-2 as a criterion standard. The results demonstrated high internal consistency for the DCDQ-2007 and a relationship with the MABC-2 was found. The DCDQ-2007 met the recommended standard for sensitivity, although the confidence interval was large; however, it failed to meet the recommended standard for specificity. This has important implications concerning the suitability of the DCDQ-2007. Although promising psychometric properties were found within the current study, the applicability of the DCDQ-2007 as a screening measure for motor difficulties requires careful consideration.
