Outline of Final Research Achievements

The results of the Rorschach in several clinical groups (schizophrenia and personality disorder/autistic Asperger's) showed that 1) Xu% has the power to differentiate schizophrenia from other clinical groups, 2) the number of popular responses (P) on card 6 is significantly higher in the personality disorder group than in other clinical groups, In other words, it has value as a differential index and 3) whether or not "black" (C') was used for that response can differentiate schizophrenia from autistic Asperger's.

Academic Significance and Societal Importance of the Research Achievements

統合失調症，自閉スペクトラム症，パーソナリティ障害とを鑑別し得る指標を抽出し得たことで，当初予定していた方法論とは異なりはしたものの，ある程度所期の目的は達成できたと思われる。今回得られた指標は，臨床実践の場において鑑別に困難を極めるケースにおいて，その判断の参考になり得よう。
適切な診断をなすことで，患者に不利益を回避させ，より精度の高い治療を提供できることは，社会的に見ても極めて意義のあることだと思われる。
