Wheelchair users risk developing secondary impairments from the loading that transfers impart on their upper extremities. The Transfer Assessment Instrument (TAI) was developed for therapists to evaluate transfer skills. This study analyzed the reliability of the TAI (version 2.0) for in-person rater and video rater evaluation methods. TAI scores were gathered from 2 sessions and 4 raters. One rater assessed randomly selected subjects from a video. Intraclass correlation coefficients (ICCs) for intra- and inter-rater reliability were calculated for in-person and video raters, and the methods were compared using Spearman's rank correlation. The inter-rater ICCS for total TAI score were 0.852 and 0.843 for sessions 1 and 2. Intra-rater ICC was 0.843(0.049) for in-person raters and 0.733 for the video rater. The relationship between methods was moderate (rho = 0.48). Overall, TAI 2.0 proved to be a highly reliable tool for in-person evaluation.
