DCDQ

The DCDQ ’ 07

The Developmental Coordination Disorder Questionnaire (the DCDQ) is a brief parent questionnaire designed to screen for coordination disorders in children, aged 5 to 15 years. It was originally developed in the late 90’s at the Alberta Children’s Hospital, Calgary, Alberta, Canada. Through further study with a population-based sample of children, a revision has been developed - the DCDQ'07 - which is available on this website.

The DCDQ'07 extends the age range to 5 - 15 year old children. Internal consistency is high. The questionnaire was studied with the parents of 287 children, aged 5-15 years, who were typically developing. Logistic regression modelling was used to generate separate cut-off scores for three age groups (overall sensitivity = 85%; overall specificity = 71%). The DCDQ'07 was then compared to other standardized measures in a sample of 232 clinically-referred children. Differences in scores on the DCDQ between children with and without coordination problems provide evidence of construct validity. Concurrent validity was evident with the Movement Assessment Battery for Children (MABC) and with the Test of Visual Motor Integration (VMI). The DCDQ'07 can be considered a valid clinical screening tool for children who have coordination challenges. A pre-print version of the full report is available here.

Translations
If you are considering translation of any of these materials that are directly downloadable from this website, please contact Brenda Wilson before beginning. After discussion, if there is an agreement on proceeding with a cross-cultural adaptation that results in a valid and reliable version of the DCDQ’07, translation guidelines will be provided.

The DCDQ’07 is available for download, with brief instructions for Administration and Scoring. An Administration Manual with evidence of the psychometric properties of this instrument is also available on this site; review of the full manual is recommended.
