Diagnostic Tests in Occupational Therapy: A Model for Evaluation

This article describes a model for the evaluation of diagnostic tests used in occupational therapy. In this model, new diagnostic tests are compared to valid tests (“gold standard”), and their sensitivity, specificity, predictive value, and agreement are calculated. The use of this method is illustrated with data from the Southern California Postrotary Nystagmus Test and the Stille-Werner Rotation Chair.
