抄録

　統合失調症患者43名と健常被験者31名に対し，情動顔の表情カテゴリーを答える課題(Facial Emotion Labeling Test；FELT)と，情動的に中性な顔に対しその明暗を答える課題(Neutral Face Rating Test；NFRT)の2種の表情認知課題を作成，施行した。FELTでは患者群が有意に低成績を示し，これは対人関係機能を中心とした社会機能の低下と関連した。NFRTでは中性顔をpositiveに認知する傾向は社会的活動性やセルフケアスキルの低評価と関連した。これら新規の簡便な課題は，統合失調症患者の表情認知障害の特徴をとらえ，また社会機能の推測に有用である可能性が示された。
