The Use of the Developmental Coordination Disorder Questionnaire in Australian Children

The concurrent validity of the Developmental Coordination Disorder Questionnaire (DCDQ) and the McCarron Assessment of Neuromuscular Development (MAND) was investigated in an Australian sample of 38 girls and 91 boys aged 9-12 years (M = 11.15, SD = 0.81). The MAND identified 44 children with motor impairment (MI) and 85 children without MI. The overall decision agreement between the two measures in identifying MI was .64. The DCDQ had a sensitivity of .55 and a specificity of .74. The DCDQ was accurate in identifying children with moderate or severe MI but identified less than half of the children with mild MI.
