This study aimed to explore the association between graphomotor tests--VMI, ROCF, SWT--and the measures of a child's participation. Seventy-five typically developing children aged 4 to 9 years were individually evaluated using the graphomotor tests and their parents completed a participation questionnaire. After controlling for child's age, the regression results have revealed the unique contribution of SWT to the total explained variance of the child's independence in participation. The less familiar SWT was found to be a better predictor of independence in participation. Therefore, it is recommended that pediatric occupational therapists become more familiar with this test and its contribution to the occupational-therapy evaluation process.
