Outline of Final Research Achievements

This study investigated the development trajectory of depressive symptoms and positive reappraisal and the relationship with emotional socialization by 5-wave annual cohort-sequential design in adolescence. The study recruited 655 adolescents who were in the fourth year of elementary school, first year of junior high school, and first year of high school during the first wave.
This study found that the frequency of positive reappraisal rapidly increased during early and middle adolescence and plateaued in late adolescence and that emotional talk with parents and peers had the positive effects on this reappraisal.

Academic Significance and Societal Importance of the Research Achievements

児童期後期から青年期後期という幅広い年齢層を対象としたことにより，いわゆるブラックボックスとなっている青年期の感情とうつ症状の発達について貴重なデータが得られた。うつ症状や肯定的再評価の発達的軌跡を明らかにし，発達の流れの中における社会的環境の影響について明らかにすることは，臨床心理学的援助に対する直接的な示唆を与えるものであると考えられる。
