Outline of Final Research Achievements	An economic intervention trial using incentives based on behavioral economics theory was conducted with the aim of promoting active prevention behavior against malaria among residents. While awaiting the final evaluation based on PCR and microscopic examination results for malaria infection, it has been shown that residents' knowledge of malaria was maintained at a high level six months later through the use of original malaria educational materials, and that the use of mosquito nets was promoted through improved knowledge. In the group where a small reward was given if malaria was negative during follow-up, although there was no significant effect on the malaria infection rate detected by rapid diagnostic test, it was revealed that the use of mosquito nets was promoted. Based on these findings, we would like to improve the incentive system design and connect it to social implementation in order to develop more effective tools.

Academic Significance and Societal Importance of the Research Achievements	世界のマラリア流行は、新たなツールの導入により2000年以降縮小に転じたが、2015年以降は横ばい、微増の傾向にある。その背景のひとつには、ツールを活用する住民の多様な予防、治療希求行動がある。本研究では、インセンティブ制度に基づく経済学的介入がその行動変容に有効なツールとなりうることを示した。今後、顕微鏡やPCRによる分子生物学的手法を含めたマラリア診断結果情報を集積し、さらに多角的に介入効果を評価したうえで、本結果を踏まえ、より効果的な政策ツールの開発のため、その内容、特にインセンティブ制度設計を改良し社会実装につなげる可能性を持つ。
