Researchers have shown the effectiveness of mindfulness on mental health, however whether the traditional mindful skills were suitable for youngsters, it was not clear. This study investigated the effects of a tailed Mindfulness-based stress reduction (MBSR) on their psychological state.Methods: A double-blind, randomized controlled trial was carried out. 56 participants who met the inclusion criteria agreed to be arranged randomly to either the MBSR group (n=28) or the control group (n=28). Participants in MBSR group received a tailored 8-week, one time per week, one hour each time group intervention. The effectiveness of intervention was measured using validated scales, which including BDI-II, MAAS, RRS at three times (T1-before intervention; T2-after intervention; T3-three months after intervention). A repeated-measures analysis of variance model was used to analyze the data.Results: The results showed significant improvements in MBSR group comparing with control group that depression level decreased after the 8-week intervention and the follow up (F =17.721, p < 0.00). At the same time, RRS score was significantly decreased at T2 and T3(F= 28.277, p < 0.00). The results also showed that MBSR promoted the level of mindfulness and the effect persisted for three months after intervention (F=13.489, p < 0.00).Conclusion: A tailored MBSR intervention has positive effects on psychology health among SD youngsters, including decrease depression and rumination level, cultivate mindfulness.Keywords: mindfulness, adolescent, subthreshold depression
