Abstract
Objective
To evaluate the reliability, standard error of measurement, minimum detectable change,
and item-level consistency of the Transfer Assessment Instrument (TAI) version 4.0
when used to evaluate transfer quality remotely.
Design
Participants transferred from their wheelchair to a mat table (transfer 1), repeated
this after a 10-minute delay to assess intrarater reliability (transfer 2), and repeated
this 1-2 days later to assess test-retest reliability (transfer 3). Each transfer
was scored in person by 4 raters and asynchronously by a remote clinician rater.
Setting
2017 National Veterans Wheelchair Games.
Participants
Convenience sample of 44 full-time wheelchair users (N=44).
Interventions
Not applicable.
Main Outcome Measures
TAI total score, subscores (wheelchair setup, body setup, flight/landing), and item
scores (15 items).
Results
Moderate to excellent reliability was found when scoring remotely for TAI total and
subscores for intrarater (intraclass correlation coefficient (ICC(3,1)=0.687-0.854),
test-retest (ICC(3,1)=0.695-0.836), and interrater reliability (ICC(3,5)=0.746-0.962).
Remote rater total score and flight/landing subscore were greater (indicating higher
transfer quality) compared to the average in-person raters (P=.021 and P=.005, respectively). There were no differences between transfers 1-3 in remote rater
scores. Item-level percentage agreement between the remote rater and in-person exceeded
the 75% cutoff for clinical utility for all items.
Conclusions
The TAI is a reliable outcome measure for assessing transfer technique remotely.
