[Test-retest and inter-rater reliability of the French version of the Ontario Society of Occupational Therapy (OSOT) Perceptual Evaluation].
This article presents the results of a study conducted to verify the test-retest and inter-rater reliability of the French version of the Ontario Society of Occupational Therapy (OSOT) Perceptual Evaluation. Designed to evaluate the perceptual deficits in patients with brain injuries, this tool uses a 5-points scale (0-4) to measure 18 different tasks. The scores obtained for each task are added to establish a total score. In the early 90s, the instruction manual of the OSOT Perceptual Evaluation was translated in French by a group of occupational therapists from l'Institut universitaire en gériatrie de Sherbrooke. To ensure the reliability of this version, a study was conducted to determine the test-retest reliability and the simultaneous inter-rater reliability. Thirty-two francophone subjects with brain injuries were each evaluated twice by the same therapist to determine the test-retest reliability of this tool. At one of the two encounters, a second therapist completed the score sheet to verify the simultaneous inter-rater reliability. The results show that, despite a few weak kappas' scores for certain tasks, the test-retest reliability and the inter-rater reliability of the total score were excellent (test-retest reliability: intra-class correlation coefficient = 0.93, with a confidence interval of 0.87 to 0.97; and inter-observer reliability: = 0.98, with a confidence interval of 0.97 to 0.99). The findings of this study show that the French version of the OSOT Perceptual Evaluation can therefore be used confidently by francophone occupational therapists.
