Participation is the measure of the amount and types of meaningful activities a person
engages in at a societal level.1
Participation of people with disability in society is a primary aim of rehabilitation
and yet definitions vary, and it is often not measured or reported.1
Participation With Recombined Tools-Objective (PART-O) is a National Institute of
Neurological Disorders and Stroke traumatic brain injury (TBI) common data element
that measures frequencies of participation within the subdomains of productivity,
social interaction, and out and about.2., 3.
There are three Yes/No items and the rest of the items are ordinal scale with higher
scores indicating more participation. Balanced scoring and Rasch scoring methods are
established on the PART-O.1
Subscale scores are calculated by taking the mean score of all items within the subscale.
The PART-O demonstrates excellent construct validity (0.61-0.82) with CIQ, CHART,
POPS, Mayo-Portland Participation Index, Cognitive FIM, Supervision Rating Scale,
Glasgow Outcome Scale extended, and Disability Rating Scale.4
PART-O has adequate construct validity (0.34-0.59) with the Motor FIM, and the Satisfaction
with Life Scale, excellent interrater reliability, and adequate internal consistency.4., 5.
Convergent validity is supported by adequate to excellent correlations between various
commonly utilized scales and at least 1 factor of the PART-O.4
The PART-O can be administered in 15-30 minutes and does not require training or
additional equipment. The measure and additional resources can be found on the Center
for Outcome Measurement in Brain Injury website.2
