The Test of Orientation for Rehabilitation Patients: Test-Retest Reliability

Abstract

The Test of Orientation for Rehabilitation Patients was developed for assessing the orientation of inpatients with brain injuries in rehabilitation settings. The test is composed of 46 items grouped into five domains of orientation: 1) Person and Personal Situation, 2) Place, 3) Time, 4) Schedule, and 5) Temporal Continuity. Test-retest reliability and magnitudes of difference between scores on test and retest were examined using subgroups of 30 rehabilitation patients with brain injuries and 32 rehabilitation patients without brain injuries. The interval between test and retest ranged from 3 to 5 days. Test-retest reliability estimates (using the two-way random effects repeated measures model of the intraclass correlation coefficient) for the total test scores were good (r = .85) to excellent (r = .95) for the non-brain-injury and brain-injury groups, respectively. Reliability coefficients for the domain scores were higher for the brain-injury group than the non-brain-injury group. However, when agreements between test and retest scores were examined, the non-brain-injury group showed greater stability.
