Assessments Used to Diagnose Developmental Coordination Disorder: Do Their Underlying Constructs Match the Diagnostic Criteria?

This study examined the constructs underlying the Movement Assessment Battery for Children-2 (M-ABC-2), Bruninks-Oseretsky Test of Motor Proficiency (BOTMP) and Vineland Adaptive Behavior Scale-2 (VABS-2) using the framework of the International Classification of Functioning Disability and Health-Child Youth version (ICF-CY) and the diagnostic criteria of developmental coordination disorder (DCD). Two independent raters coded and matched items to ICF-CY codes as per the eight ICF linking rules developed by Cierza and colleagues. Content density and inter-rater reliability were also calculated. The majority of codes assigned to the M-ABC-2 and BOTMP related to body functions (54% and 64% respectively). For the VABS-2, 91% of codes pertained to activities and participation. The M-ABC-2, BOTMP, and the VABS-2 emphasize the ICF-CY constructs differently. The VABS-2 may be useful in the evaluation of performance of daily life activities and participation in children with DCD.
