Outline of Final Research Achievements

With the aim of elucidating the mechanism of action of psychotherapy, Study 1 used data from a clinical trial of remote cognitive-behavioral therapy for insomnia to create a corpus containing outcome data, Th treatment compliance data, video, audio, and verbatim data, etc., and Study 2 used outcome data in the corpus, Study 2 used outcome data from the corpus to examine differences in linguistic characteristics between insomniacs with and without comorbid depression. The results showed that although there were no differences in the use of first-person pronouns or the length of utterances, which have been pointed out in previous studies, there was a diversity of topics in the group with concomitant depression. In the future, we plan to examine the patterns of change in outcomes based on data from multiple modalities.

Academic Significance and Societal Importance of the Research Achievements

心理療法のプロセスを検証した多くの先行研究では、模擬面接等のデータを使用しており実際の心理療法中のマルチモーダルデータをを格納するレジストリを構築した研究はまだない。これらを踏まえて本研究では、アウトカムデータと結びついたコーパスの作成、言語的特徴の抽出を行った。本研究の研究成果は効果的な心理療法に資するものであり、今後の臨床心理学における適切なマルチモーダルデータの収集について、示唆を与えるものといえる。
