The effectiveness of the DNA-V program on reducing anxiety among Chinese adolescents: Outcomes of the face-to-face and web-based versions

Many studies have indicated an alarming prevalence of anxiety among Chinese adolescents, highlighting the critical need for prevention protocols. DNA-V (Discoverer, Noticer, Advisor-Values model) is an adapted version of Acceptance and Commitment Therapy designed to prevent mental health problems in adolescents. This study investigated the effects and underlying mechanisms of DNA-V. The DNA-V prevention program was culturally adapted and optimized in both content and form specifically for Chinese adolescents, with the aim of reducing anxiety levels. A total of 139 participants (59 females) from six eighth-grade classes at an average middle school in Beijing were randomly assigned to one of three groups consisting of the DNA-V face-to-face group (two classes), the DNA-V web-based group (two classes), or the active control group (two classes). Adolescents' anxiety and cognitive fusion were measured before (Time 1), immediately after (Time 2), and 2 months after (Time 3) the program using the Chinese Secondary School Students Anxiety Scale (CSSSAS) and Cognitive Fusion Questionnaire (CFQ). Results showed that in the DNA-V face-to-face group, the anxiety score at Time 3 was significantly lower than the scores at Time 1 (p
