This paper provides a description of an online Rorschach interpretation algorithm for the Exner comprehensive system, as well as a study conducted to evaluate the validity of the online interpretive algorithm. The user, systems, and equipment specifications for the algorithm are explained, and the potential advantages of its use to enhance clinical efficiency and clinician skill in decision making are discussed. The validity of the online interpretation was tested by asking two expert clinicians to compare the computerized output with the structural interpretation used in the text for 10 sets of Rorschach reports. The computer-generated narratives were found to be as useful as clinician reports in four of the six characteristics reported, and possible solutions to the problems with the remaining two dimensions are suggested. Sixteen references are cited. (MER)
