Follow-up Validation of Rorschach Tempo and Color Use Indicators of Schizophrenia

Two to five year psychiatric follow-ups through a case register of original cross-validating samples for some Rorschach tempo and color use indicators of schizophrenia found subsequent diagnosis of schizophrenia associated (a) beyond the .001 level with certain deviations from normative tempo and (b) beyond the .01 level with presence of pure C or two or more of the following: 1–2 CF, Sum C 1.5–3.0, CF without C. Combined classification by the tempo and color variables was accurate in 90% of schizophrenic and 80% of nonschizophrenic cases manifesting neither or both variables. These findings, occurring within a population of psychiatric patients referred for testing, recommend the clinical utility of the variables.
