Children with probable DCD had low scores on behavior assessments such as VMI, MABC and MHA.
Children with probable DCD showed high temporal, not spatial, variability in repetitive letter writing tasks.
The MABC is a good predictor for evaluating the temporal consistency of repetitive letter writing.
The VMI, MABC and MHA scores could not predict the spatial characteristics of repetitive letter writing.
Children with probable DCD had prominent difficulties on the temporal aspect of handwriting.
