Measurement Characteristics and Clinical Utility of the Participation With Recombined Tools-Objective Measure in a Traumatic Brain Injury Population

Abstract

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 This abbreviated summary provides a review of the psychometric properties of the PART-O in adults with TBI. A full review of the PART-O and reviews of over 460 other instruments for patients with various health conditions can be found at: www.sralab.org/

A Network Analysis of the PART-O at 1 and 2 Years After TBI: A Veterans Affairs Model Systems Study

“…Each item is rated from 0 to 5 based on the frequency of a specific activity within a designated period (eg, typical week). The PART-O-17 produces a total score and 3 domain scores: Productivity (3 items), Social Relations (7 items), and Out and About (7 items) 17. Each subscale score is computed as the average response to all respective items, producing a score ranging from 0 to 5.…”
