To examine the internal consistency, test-retest reliability, and responsiveness of the Movement Assessment Battery for Children-Second Edition (MABC-2) Test for children with developmental coordination disorder (DCD).


One hundred and forty-four Taiwanese children with DCD aged 6 to 12 years (87 males, 57 females) were tested on three separate occasions: two baseline measurements with a 20-day interval before the intervention, and a follow-up measurement after 6 months of rehabilitation. The therapists rated the performance of children in school-related physical tasks at baseline and after intervention.


Internal consistency for the MABC-2 Test was α = 0.90. Test-retest reliability for the total score was excellent, with an intraclass correlation coefficient of 0.97. A small to medium magnitude of treatment effect was captured by the MABC-2 Test. The minimal detectable change (MDC) was 0.28 points whereas the minimal important difference (MID) values were from 2.36 to 2.50. All subscales except balance showed acceptable validity in differentiating groups of children whose physical performance had improved or remained stable.


The MABC-2 Test is a reliable and valid measure to assess motor competence in children with DCD. The MID and MDC scores provide the reference point for clinical decision-making in managing the individual child.
