Outline of Final Research Achievements |
Based on the notion of self-disorder as a core disturbance of schizophrenia and the significance of FRS in schizophrenia diagnosis, we hypothesized that this scale of self-disturbance-related attributes could be predictive for schizophrenia development. In the present study, we developed a scale to measure MMPI-derived attributes found in schizophrenia patients with self-disturbances of FRS. The newly developed Self-A to assess the attributes relating to the self-disturbances of FRS revealed the adequate reliability and validity.

Academic Significance and Societal Importance of the Research Achievements |
統合失調症は若年期に発症する代表的な精神疾患の一つであり、機能低下を伴いながら慢性化する傾向があり、治療開始の遅れは臨床転帰に悪影響を及ぼすため、早期診断・早期治療が重要となる。現在、統合失調症を含む精神病性障害の発症リスク状態(ARMS)は臨床的特徴により診断されるが、ARMSから精神病への移行率は2年間で約30%、そのうち統合失調症が約60%程であり、より高い精度で精神病発症を予測する指標の開発が求められている。今回開発したSelf-Aは、神経認知機能、神経生理学的機能、神経脳画像による脳構造・脳機能など他の予測マーカーと組み合わせることで統合失調症の早期診断の向上に寄与すると考えられる。
