Can thiệp “Happy house”: Kết quả sự thay đổi căng thẳng, lo âu và trầm cảm ở học sinh tại 8 trường trung học phổ thông của Hà Nội

To assess the effects of Happy House program on stress, anxiety and depression among grade-10 students in 8 high schools in Hanoi. Methods: A school-based, two-arm parallel controlled trial was conducted in Hanoi from 2020 to 2023. A total of 531 students received six weekly 90-minute group sessions of Happy House (Intervention group); and 552 students received the usual curriculum (Control group). The outcomes were measured using the 21-items Depression, Anxiety and Stress. Data were collected at pre-intervention, and at two weeks and six months post-intervention. Mixed-effect models were conducted to estimate the effects of the intervention on the outcomes at an individual level following intention-to-treat principles. Results: The mean scores of stress, anxiety and depression in the Intervention group decreased at 2-week and 6-month follow-up, but the differences were not statistically significant compared to the control group. At 2-week post-intervention, Happy House program had an impact on reducing stress and depression symptoms among female students. However, there were no differences at the six-month follow-up between the two groups or between males and females. Conclusion: Further research with a more robust study design using diagnostic tools is warranted to confirm the findings of this study.
