title: Evaluation in an inpatient setting of DTREE, a computer-assisted diagnostic assessment procedure.
abstract: This study examined the procedural validity of DTREE, a microcomputer-based expert system that guides the user through the diagnostic logic of DSM-III-R. A DTREE-guided DSM-III-R diagnosis of 20 inpatients (made by the treating clinician) was compared with a "standard" diagnosis made simultaneously during a weekly 2-hour case conference consisting of a presentation by the treating clinician and other staff, a chart summary, and the administration of the Structured Clinical Interview for DSM-III-R (SCID), and culminating in a group consensus diagnosis. The kappa agreements were .80 for schizophrenia (N = 10), .83 for major depression (N = 3), and -.08 to 1.00 for other disorders. These results suggest that DTREE can produce valid assessments, at least in an acute setting of primarily patients with schizophrenia.
