&ldquo;Rorschach Schizophrenic Score&rdquo; (RSS) provides a method for an objective and quantitative analysis of the Rorschach protocols with a purpose of differentiating schzophrenia from other clinical groups, especially psychoneurosis.<BR>RSS was first prepared for the examination of 1) general formal scoring categories, 2) form level ratings, 3) B&uuml;hler's Basic Rorschach Score, and 4) Watkins & Stauffacher's delta %.<BR>As a result, it was found that P, R+% (including all the primary form responses), W-%, BRS and delta % were the factors by which schizophrenic group was differentiated from psychoneurotic group at 0.5% level of confidence (t-test). Hence these five factors were synthesizes by Fisher's &ldquo;discriminant function&rdquo;.<BR>We obtained by this statistical method Z score of -14.13, which was the cut-off point between schizophrenia and psychoneurosis. Thus Z&le;-14.13 was called &ldquo;Rorschach Schizophrenic Score&rdquo; (RSS) and 77% of schizophrenic group came within this score.<BR>Subjects used in this research were as follows :<BR>1) Schizophrenic group (SGr.) N=30<BR>These patients have been diagnosed undoubtedly as chronic schizophrenia which were considered comparatively fresh cases by more than two psychiatrists.<BR>2) Psychoneurotic group (PGr.) N=30<BR>This group consisted of eight anxiety neurotics, three hysterics, five obsessivecompulsive neurotics, six neurosthenics and eight neurotics of mixed-type who had visited the National Institute of Mental Health for treatment.<BR>3) Normal group (NGr.) N=30<BR>They were well-adjusted adults and have never undergone any psychiatric treatment. The subjects mentioned above were homogeneous with regard to the following conditions : age, sex, educational level, socio-economic level and so on.<BR>The protocols which had less than 10 reponses were omitted because of difficulty for diagnosis in many cases.
