Test Validity Measures and Receiver Operating Characteristic (ROC) Analysis
Teaching module content: Diagnosis is based on the results of diagnostic tests. Most of them are imperfect instruments, and make errors in both directions - a healthy individual can be classified as diseased, and vice versa. Ability of each diagnostic test to correctly classify patients as diseased or healthy is called validity of test. Concept apply also in screening tests. There exist several nosological (sensitivity, specificity, etc.) and diagnostic measures (ositive predictive value, negative predictive value) to assess validity of a test with a binary outcome. In other tests ROC method could be used as a method of analysis. After completing this module students should: 1) understand measures of tests validity and differences between them ; 2) know how to calculate these measures and be capable to calculate them by themselves ; 3) understand principles of ROC analysis, and how basic measures of tests validity are related to ROC analysis.
