Purpose:
To determine if there is a homogeneity of scores for youth with intellectual disability (ID) with and without Down syndrome (DS) in 19 test items of motor competence from the Bruininks-Oseretsky Test of Motor Proficiency-Second Edition (BOT-2). Homogeneity was defined as the means for each of the 19 test items scores by sex and the presence or absence of DS sharing the same population mean.
Method:
Participants were 622 youth with ID aged 6 to 21 years. Items for bilateral coordination, balance, and upper limb coordination were examined using the BOT-2.
Results:
For all 19 BOT-2 items, means between youth with and without DS did not differ from the population mean.
Conclusion:
These results potentiate the development of expected BOT-2 motor competence scores for youth with ID independent of the presence of DS for clinical practice.
