• Evaluation of psychiatric screening and diagnostic tests has benefited from the application of sensitivity, specificity, the k-statistic, and predictive values. These measures derive their meaning from a single criterion threshold. Receiver operating characteristic (ROC) analysis extends assessment of test performance by providing information about all possible pairs of achievable sensitivity and specificity values. The ROC analysis offers a comprehensive means for comparing different tests or different scoring procedures for one test. As a demonstration we used the ROC analysis to evaluate three types of scoring rules for one psychiatric test, the Health Opinion Survey. The demonstration indicated that ROC analysis can profitably take a place among the standard methods for test evaluation in psychiatric research. In addition, ROC analysis can assist clinicians in selecting appropriate test procedures for particular patient populations.
