Outline of Final Research Achievements

The author conducted research and activities on three domains related to rumination-focused cognitive-behavioral therapy (RFCBT): studies on (1) outcome measures and (2) practice, and work related to (3) dissemination. (1) The author conducted two cross-national studies to compare the levels of rumination and its relationships to depression in the U.K. and Japan. The results of the cross-sectional study showed that rumination was more prevalent in the U.K., and the cross-sectional association was stronger in the U.K. than in Japan. However, rumination was shown to be significantly related to depression among Japanese population as well. (2) The effectiveness of the RFCBT self-help program was examined using a multiple baseline design for female university students with high tendency to ruminate or worry. (3) We published a Japanese translation of the RFCBT manual (Watkins, 2016).

Academic Significance and Societal Importance of the Research Achievements

第一に，反すうの特徴や抑うつとの関連はこれまで欧米のサンプルで検討されており，我が国のサンプルにおいては従来十分なデータがなかった。本研究課題の実施により，我が国のサンプルにおける反すうの記述的特徴に関するエビデンスが得られ，反すうに焦点化した支援を行う根拠の一つとなると考えられる。第二に，RFCBTの有効性をデータから示したことで，RFCBTが我が国の人口においても役立ち得ることを原理証明的に示した。最後に，そのように有効な方法の普及に努め，支援者向けのマニュアルの翻訳を行ったことで，支援の裾野が広がり，我が国でのより良い実践に向けて多様なフィードバックが得られる基盤を整えた。
