Outline of Final Research Achievements

The objective of this research was to investigate the mechanism of the impact of childhood trauma in adulthood. The research was designed based on multiple psychological theories. Specifically, three main studies were conducted. Firstly, I examined the reliability and validity of the Childhood Trauma Questionnaire (CTQ-JNIMH) in a Japanese sample, which is a globally recognized measurement scale for childhood trauma. Secondly, I conducted a study based on the hypothesis derived from the diathesis-stress model. Thirdly, I conducted an investigation focusing on the intergenerational transmission of childhood trauma, considering the Social Support Theory.

Academic Significance and Societal Importance of the Research Achievements

児童期トラウマとは、虐待やネグレクトなど、18歳未満でのトラウマ的経験である。児童期トラウマによる影響は長期的なものであり、被害者の子ども時代だけでなく、成人してからも様々な困難を誘引するリスクとなり得ることが示唆されてきた。そこで本研究では、成人期における児童期トラウマによる影響について、複数の心理学的理論を基にした調査を行い、当事者の生きづらさを解消するために必要な支援について考察した。
