Our results provide support for the validity and reliability of the MPFI-EMA. However, validity for assessing within-person variability remained unclear, psychometric limitations were observed for some subscales, and reactivity over time occurred for the MPFI-EMA Psychological Inflexibility scale and specific subscales. Limitations include the use of novel cutoffs, as criteria for psychometric validation within EMA are not well-established, and the need for replication in diverse samples, including clinical populations.</div></div>","PeriodicalId":47544,"journal":{"name":"Journal of Contextual Behavioral Science","volume":"36 ","pages":"Article 100903"},"PeriodicalIF":3.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144107613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, there is a need to design and apply university-based interventions that are easily accessible to college students. Transdiagnostic Internet-based Acceptance and Commitment Therapy (TACT) has been widely utilized due to its low cost and scalability; however, to date, its effectiveness and cross-cultural adaptation in mainland China remain to be studied. University students were recruited and randomly assigned to either a) the intervention group (n = 48, Student COMPASS Enhanced Course), which received the I-ACT intervention course with cross-cultural adaptation modifications, or b) the control group (n = 48, Student COMPASS Course), which received the Student COMPASS Course, in a randomized controlled trial design. The Student COMPASS Enhanced Course is a program that has undergone cultural adaptation improvements. The course utilizes the Theoretical Model of Confucian Self-Development as the ethical guideline, while mapping Zeng Guofan's (1811–1872) experience of self-cultivating to the six sub-processes of psychological flexibility and become the essential part of the course. Participants all received a post-intervention assessment after 7 weeks and a follow-up assessment after 15 weeks. The results indicated time effects across all symptom measures (ISI, GHQ-12, PPFI, ESS, DASS-21, and AAQ-II), suggesting significant improvements in mental health, sleep health, and psychological flexibility over time in both the intervention and control groups. Additionally, between-group main effects were observed for PPFI, ESS, DASS-21, and AAQ-II scores.
