Variables

COMBINE includes two types of variables :

required & 
recommended
 

Consortium Members who contribute data must have all of the required variables, in order to ensure that there is sufficient data to answer primary questions about motor behavior & neurodivergence.

Consortium Members may also choose to contribute data for any of the recommended variables. This will enable examination of more complex relationships between domains of ability related to motor behavior.

All data contributed to & stored in the COMBINE dataset are deidentified.

Required Variables

At least one of the following standardized motor assessments:

  • Movement Assessment Battery for Children (MABC) – 2nd edition (scores & band number)

  • Peabody Developmental Motor Scales (PDMS) – 2nd edition (scores)

  • Bruininks-Oseretsky Test of Motor Proficiency (BOT) – 2nd edition (scores from short form or full form)
