This paper describes the implementation of a computer-based approach to scoring open-ended problem lists constructed to evaluate student and practitioner clinical judgment from real or simulated records. Based on 62 previously administered and scored problem lists, the program was written in BASIC for a Heathkit H11A computer (equivalent to DEC PDP11/03). In addition to a scoring program, the complete package requires five other files: the scoring key, a dictionary of preferred expressions, the spelling algorithm, a program for preparing scoring keys, and a program for printing text files. The basic scoring structure consists of a short sequence of logical rules and a very long list of terms and equivalent expressions and stems which make up the logical data. A typical program output for one subject for one case would display not only counts of each error type, but also an accounting for each term on the problem list. The program provides a method of consistently evaluating scoreable problem lists without the use of faculty time. It also can be used for instructional purposes, not only providing a student with instantaneous feedback, but also with comments on performance in preparing a problem list from a set of clinical signs and symptoms.
