Does the Movement Assessment Battery for Children-2 at 3 years of age predict developmental coordination disorder at 4.5 years of age in children born very preterm?

Abstract

BackgroundVery preterm children (VPT) are at high risk for developmental coordination disorder (DCD). The Movement Assessment Battery for Children-2 (MABC-2) Test is commonly used to identify children with DCD, but little is known about the predictive validity of this assessment in this population. AimsThe aims of this study were to determine if MABC-2 scores at 3 years can predict DCD at 4.5 years and if DCD can be reliably identified in VPT children at 3 years. Methods and proceduresIn a retrospective sample of 165 VPT children, logistic regression was used to determine if the MABC-2 score at 3 years is predictive of DCD at 4.5 years. Cross-tabulations were used to determine the relationship between scores at 3 years and DCD at 4.5 years. Outcomes and resultsMABC-2 scores at age 3 were a significant predictor (OR = 0.82, p = 0.001) of DCD diagnosis at 4.5 years. The MABC-2 has excellent sensitivity (90%), moderate specificity (69%), small to moderate positive predictive value (38%) and high negative predictive value (97%). Conclusions and implicationsThe MABC-2 is highly sensitive in identifying VPT children with DCD, but also has many false positives. MABC-2 scores can reliably predict VPT children who are not at risk of DCD.
