This research was designed to obtain information on the validity and reliability of three new evaluation techniques: (1) The Simulated Patient Management Problem (PMP), a written simulation exercise; (2) The Simulated Diagnostic Interview (DI), an oral exercise; and (3) The Simulated Proposed Treatment Interview (PTI), another oral exercise. These techniques are used for assessing the clinical competence of physicians. A review of related research follows a brief discussion of the purpose of the study. Following this section is a discussion on the conceptual problems in evaluating the validity of achievement tests. Chapter Five goes on to describe the three evaluation techniques listed above. This description is followed by: (1) analysis of the reliability of the techniques; (2) analysis of the construct validity of the techniques; and (3) analysis of the concurrent validity of the techniques. The last two parts of the paper present conclusions reached as a result of the study, and areas for further research. (SJ)
