Mindfulness-based cognitive therapy for perceived stress and psychosomatic symptoms in Chinese adolescent girls: a mixed-methods school-based study of parent and teacher perceptions

School-delivered MBCT was associated with sustained improvements in perceived stress and psychosomatic complaints among 14-16-year-old girls, with convergent qualitative evidence from parents and teachers. Interpretation remains cautious given the passive control, short follow-up, and bounded generalizability. Future work should test MBCT against attention-matched/active comparators, extend follow-up to 6-12 months, and examine mechanisms (e.g., decentering, rumination) and cultural/implementation outcomes to inform scaling in diverse Chinese school contexts.
