The aim of this study was to investigate the validity and reliability of the
Movement Assessment Battery for Children-2 Checklist (MABC-2). METHOD: Teachers
completed the Checklist for 383 children (age range 5-8y; mean age 6y 9mo; 190
males; 193 females) and the parents of 130 of these children completed the
Developmental Disorder Coordination Questionnaire 2007 (DCDQ'07). All children
were assessed with the MABC-2 Test. The internal consistency of the 30 items of
the Checklist was determined to measure reliability. Construct validity was
investigated using factor analysis and discriminative validity was assessed by
comparing the scores of children with and without movement difficulties.
Concurrent validity was measured by calculating correlations between the
Checklist, Test, and the DCDQ'07. Incremental validity was assessed to determine
whether the Checklist was a better predictor of motor impairment than the
DCDQ'07. Sensitivity and specificity were investigated using the MABC-2 Test as
reference standard (cut-off 15th centile). RESULTS: The Checklist items measure
the same construct. Six factors were obtained after factor analysis. This implies
that a broad range of functional activities can be assessed with the Checklist,
which renders the Checklist useful for assessing criterion B of the diagnostic
criteria for DCD. The mean Checklist scores for children with and without motor
impairments significantly differed (p<0.001). The scores for the Checklist/Test
and DCDQ'07 were significantly correlated (r(S) =-0.38 and p<0.001, and r(S)
=-0.36 and p<0.001, respectively). The Checklist better predicted motor
impairment than the DCDQ'07. Overall, the sensitivity was low (41%) and the
specificity was acceptable (88%). INTERPRETATION: The Checklist meets standards
for validity and reliability.
