摘要

The goal of this column is to help working clinicians understand the statistical calculations involved in interpreting the results of diagnostic questionnaires. Using the Patient Health Questionnaire-9 as an example, the author explains how to determine the most appropriate cutoffs to choose, depending on the population involved, the probabilities of error (a and {), and the expected losses associated with each kind of error in the context in which the test is being administered. (Journal of Psychiatric Practice. 2011;17:57-60).
