Considerations in collecting Rorschach reference data

Recent Rorschach research with nonpatients has yielded reference data that differ in several respects from nonpatient normative data published for the Comprehensive System (Exner, 1995). Conclusions concerning the implications of these new findings are premature, however, pending careful consideration of appropriate guidelines for collecting Rorschach reference data. In proposing guidelines for future research of this kind, I note (a) that the relatively unstructured nature of Rorschach assessment may complicate obtaining useful data from nonpatient volunteers, (b) that normative studies should include various types of patient as well as nonpatient samples, and (c) that identification of psychological disturbance from Rorschach protocols may be guided more accurately by how closely a record resembles the records of patients with certain disturbances than by how much the record differs from the records of nonpatients.
