Outline of Final Research Achievements

We examined the risk of developing eating disorders in college students using a questionnaire and created a prevention program. Furthermore, we focused on the subthreshold group at high risk of developing eating disorders.We examined the relationship between disoredered eating behavior, depressive symptoms, and stress coping behavior. The results revealed that depressive symptoms and stress coping behaviors are associated with the risk of developing disoredered eating disorders. Prevention of eating disorders requires not only improvement of depressive stmptoms but also stress coping skills. Therefore, we modified the prevention program for eating disorders by adding cognitive-behavioral therapy approaches to stress management (e.g., problem-solving techniques).

Academic Significance and Societal Importance of the Research Achievements

摂食障害は若年者を中心とする患者数増加や発症後の慢性化が深刻な問題であるが、有効な治療法は確立されておらず、予防や早期介入が重要な課題となっている。近年、摂食障害の診断基準を満たさない摂食障害の閾値下群の若者が多く存在していることが注目されている。摂食障害の予防的援助を行うには、閾値下群の特徴に注目して、効果的な早期介入を行うことが必要である。本研究では、閾値下群を対象に食行動異常の増悪因子を明らかにし、予防プログラムを作成した。
