| Outline of Final Research Achievements |
In Japan, approximately 180,000 minor children experienced parental divorce in 2021. Research in Japan has mainly been limited to cross-sectional surveys, making it difficult to estimate causal relationships and identify changes in children's adjustment over time. In the present study, mothers (N=500) who had been divorced for less than two years and were living with their children (aged 2-17 years) received follow-up assessments after two years. Approximately half of the participants responded after one year, and 34% responded after two years. Data from three time points were analyzed using a cross-lagged effects model. Conflictual co-parenting was found to have a positive effect on externalizing problems.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の学術的意義は，第1に，葛藤的なコペアレンティングと子どもの外在化問題との間に正の関連が示され，父母の葛藤が子どもに悪影響を与えることが日本のデータでも裏付けられたことである。第2に，2年間という短期間ではあるものの，離婚家族を追跡したデータが得られたことが挙げられる。
本研究の社会的意義は，離婚後に葛藤的なコペアレンティングが高まらないような働き掛けが重要であることが示唆されたことである。親支援プログラムなどにおいては，葛藤を低減することの重要性をより強調することが必要であると考えられる。
