Background: Ultra-high risk (UHR) individuals of developing psychosis are known for their heterogeneity. Therefore, it is presumed that the baseline personality functions of UHR individuals who made a transition to psychosis are also heterogeneous. The aim of present study was to investigate the variety of baseline personality functioning of UHR individuals converting to psychosis using the Rorschach Comprehensive System, one of the most widely applied standardized personality tests. Method: The study sample comprised of 12 UHR patients examined at the psychiatric outpatient unit of the Toho University Omori Medical Center, Tokyo, Japan. Out of 12 included UHR subjects, two converted to psychosis within the six-month follow-up period. The transitioners’ baseline Rorschach data were investigated and compared to that of the non-transitioners’ in addition to the Rorschach normative data. Results: The Rorschach baseline data of the two transitioners differed with respect to various variables, including the style of information processing (W:D:Dd), efficiency of the information scanning (Zd), developmental quality of information synthesis (DQ+), cognitive mediation (XA%, WDA%), ideation (M-, WSum6), self-perception (3r+[2]/R), and affect regulation (FC: CF+C) . The both transitioners’ Perceptual-Thinking Index (PTI) were higher than the normative score, however, there were non-transitioners who showed higher-than-normative PTI and did not convert to psychosis. Conclusions: This study suggests that transitioners’ baseline personality functions are heterogeneous. Therefore, there are various domains of personality functioning that ought to be considered when predicting the potential to transition to psychosis. These results should be examined using larger samples.
