Abstract
DTREE has been developed to provide new clinicians with computer-assisted teaching of psychiatric diagnosis, according to the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised (DSM-III-R). At the core of DTREE is an expert system that guides the user through the process of making a diagnosis. To best model the DSM-III-R system, a decision tree design has been employed in which questions are sequentially asked about a case, with the answer determining which question is asked next. Since the primary goal of an expert system used for teaching is to be able to provide explanations of what it is doing, annotated comments and additional explanatory text are available for each question that is asked. DTREE is currently undergoing field testing in both clinical and educational settings.
