AIM: To assess the predictive validity at 4 years of the Movement Assessment
Battery for Children - Second Edition (MABC-2) for motor impairment at 8 years in
children born preterm.
We also aimed to determine if sex, cognition, medical, or
social risks were associated with motor impairment at 8 years or with a change in
MABC-2 score between 4 years and 8 years. METHOD: Ninety-six children born at
less than 30 weeks' gestation were assessed with the MABC-2 at 4 years and 8
years of age. Motor impairment was defined as less than or equal to the 5th
centile. The Differential Ability Scales - Second Edition (DAS-II) was used to
measure General Conceptual Ability (GCA) at 4 years, with a score <90 defined as
'below average'. RESULTS: There was a strong association between the MABC-2 total
standard scores at 4 years and 8 years (59% variance explained, regression
coefficient=0.80, 95% confidence interval [CI] 0.69-0.91, p<0.001). The MABC-2 at
4 years had high sensitivity (79%) and specificity (93%) for predicting motor
impairment at 8 years. Below average cognition and higher medical risk were
associated with increased odds of motor impairment at 8 years (odds ratio
[OR]=15.3, 95% CI 4.19-55.8, p<0.001, and OR=3.77, 95% CI 1.28-11.1, p=0.016
respectively). Sex and social risk did not appear to be associated with motor
impairment at 8 years. There was little evidence that any variables were related
to change in MABC-2 score between 4 years and 8 years. INTERPRETATION: The MABC-2
at 4 years is predictive of motor functioning in middle childhood. Below average
cognition and higher medical risk may be predictors of motor impairment.
