 The purpose of the present study was to identify the initial symptoms of schizophrenia by using psychological tests. Useful high frequency symptoms for diagnosing early schizophrenia proposed by Nakayasu were evaluated and the Minnesota Multiphasic Personality Inventory(MMPI) and Rorschach test were conducted for 18 patients with early stage schizophrenia and 18 healthy adults. Results of the early symptom rating form showed that patients with early schizophrenia and not healthy adults had symptoms of autochthonous fantasy, heightened auditory perception, vague feelings of being observed, anhedonia, excessive interpersonal strain, and persecutory ideation compared to healthy adults, early schizophrenia patients had higher scores of the F scale and on eight clinical scales on the MMPI. Further in the Rorschach test, patients showed low animal movement response (FM score), vista response(FK score), popular response(P score), and modified Basic Rorschach Score, and high inanimate movement response(m score), texture response(c score), and usual detail response(D score). Our findings suggest that these indices can be potentially used to identify the initial symptoms of schizophrenia.
