The development of an on-line MMPI interpretative program is outlined. Profiles interpreted by this program are first examined to determine whether a standard or locally known profile type fits. If so, an appropriate narrative report is printed. If there is no match with a known profile type, statements from several scale-by-scale interpretative sources are organized into a logical report. Methods have been developed to eliminate duplication and contradiction from different sources of information. Examples of output from this program are presented and advantages of the program are discussed.
