| Outline of Final Research Achievements |
Participants were recruited from February 2018 to January 2022. Of the 68 patients who were initially recruited, 32 were registered in this study, and 24 completed it (completion rate, 75% (24/32)). Thirty-six patients were not registered because they did not meet the diagnostic criteria for major depressive episodes according to the Mini-International Neuropsychiatric Interview. The total HAMD17 score significantly improved after the program with large effect sizes (Hedge’s g =1.95). The remission rate of depression was 62.5% (20/32). BA was considered useful because the remission rate after the program exceeded the pre-defined threshold of 30%. All secondary outcomes except VQ-O and RPI Reward Skill were significantly improved immediately after the program and 3 months later (p<0.05). Two patients dropped out from the study due to mental symptoms. The pre-scores of HAMD17 for them were 24 and 31, respectively.

| Academic Significance and Societal Importance of the Research Achievements |
本研究成果により、行動活性化療法は、がん患者の抑うつ状態を改善するだけでなく、患者ががんの経過と上手に向き合い、自分の価値観に基づいてより充実した人生を送るための幅広いサポートになる可能性がある。このことは、BAが心理療法を補完し、がん患者の包括的な支援方法として機能する可能性を示唆している。
