Outline of Final Research Achievements

The series of studies expanded quantitative model that describes the adaptation to the Potentially Traumatic Events (PTEs) to the everyday experiences of working individuals. In an intervention experiment conducted in Fiscal Year 2022, participants showed low metacognition regarding memory tasks simulating work and tended to assign meaning to simple tasks that are generally considered to have little academic significance. The findings were presented at an academic conference in the U.S. in Fiscal Year 2023 and received high acclaim. In Fiscal Year 2024, further research suggested that depending on individual psychological traits, simple tasks could have adverse effects, and forced meaning-making might lower performance. On the other hand, maintaining a positive mindset was found to enhance sensitivity to positive experiences. These results highlight the importance of tailoring interventions to individual and situational characteristics.

Academic Significance and Societal Importance of the Research Achievements

災害時におけるPTEへの心理的適応モデルを、就業者が日常的に経験するPTEに応用するという新たな取り組みが学術的・社会的意義が高い。例えば、個人の心理特性が介入効果に与える影響を実証的に明らかにした。これにより、個別最適化された介入の必要性を示唆し、健康科学に新たな知見を提供した。現代の職場環境における日常のPTEに対し、誰もが実践できるシンプルな認知課題やマインドセットの調整によって、心理的な適応力を高める可能性を示した。また、画一的な対処法では逆効果となる場合があることを明らかにし、個人や状況に応じた柔軟な支援の重要性を示し、企業のメンタルヘルス対策や予防的介入のあり方に示唆を与えた。
