Abstract

Aim: The aim of the current study was to determine if the newly developed DCDdaily questionnaire is a better screening instrument for developmental coordination disorder (DCD) than the commonly used parental questionnaires; the Developmental Coordination Disorder Questionnaire (DCDQ) and the Movement Assessment Battery for Children-2 Checklist. Method: Reliability was measured by determination of the internal consistency. Sensitivity, specificity and incremental validity of the DCDdaily questionnaire were calculated in a population based group (n=186; age range S-8 y; 85 boys) and in a clinical-referred/control group (n=21 DCD and 21 TD; age range S-8 y; 38 boys) using the performance on the MABC-2 test as a reference standard (cut-off 15th centile). The DCDdaily questionnaire, the DCDQ and the MABC-2 Checklist were filled out by parents. Results: The internal consistency of the DCDdaily questionnaire was considered very good, implying that all items measure the same underlying construct 'ADL motor performance'. Mean scores on the DCDdaily questionnaire were significantly worse for children with DCD or probable DCD (p<O,OOl) compared to TO children. Sensitivity in the population based group was low (18%) and high (90%) in the clinical-referred/control group. Specificity was high in the population based group (94%) and in the clinical-referred/control group (100%). Results regarding the incremental validity show that the DCDdaily questionnaire did not predict motor impairment better than the DCDQ or MABC-2 Checklist. Conclusion: The results imply that the DCDdaily questionnaire can be reliably used to identify children who are diagnosed with DCD. It can be used as a tool to assess criterion B of the DSM-IV in addition to currently used instruments. However, as the sensitivity in the population based group is low, the DCDdaily questionnaire should not be used as screening method in a population based group.
