Welcome to the DCDQ website, and thank you for your patience as we completed the development of the Little DCDQ.
The Little Developmental Coordination Questionnaire is a parent report measure that screens for motor coordination difficulties in 3- and 4- year old children. It consists of 15 items, which group into two distinct factors: 1) gross motor skills and 2) fine motor skills. The Little DCDQ measures functional skills in several contextual areas across home and preschool environments and during play activities.
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, Canada. Through further study with a population-based sample, a revision has been developed - the DCDQ'07 - which is available here, with a brief Administration and Scoring guide.
The DCDQ'07 extends the age range to 5 - 15 year old children. The questionnaire was studied with the parents of 287 children 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 MABC and with the VMI. The DCDQ'07 can be considered a valid clinical screening tool for children who have coordination challenges. 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.
The DCDQ and some translations have been available free-of-charge. Due to the costs of maintaining this website and in order to support further validation of all versions of the DCDQ, we are charging a nominal fee for purchase of the Little DCDQ-CA:
