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.
Trial report in BMC psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMindfulness-Based Cognitive Therapy (MBCT) integrates mindfulness practices with cognitive strategies to alleviate perceived stress and its associated symptoms. While well studied in adults, evidence for school-based MBCT among adolescents with psychosomatic complaints-particularly in China-remains limited.
methodsWe conducted a quasi-experimental, mixed-methods study in three public secondary schools in DaZhou (Sichuan, China). Female students aged 14-16 were screened (N = 1,200) using the Psychosomatic Complaints Scale (PCS; cutoff > 45) and DSM-5-informed clinical interviews; 60 eligible students were randomly allocated to MBCT (8 weekly 75-minute sessions) or school-as-usual control. To mitigate non-specific effects, controls received attention-balanced administrative contacts (weekly neutral check-ins without psychological content). Outcome assessors and the data analyst were blinded to allocation. The primary outcomes were the Perceived Stress Scale (PSS; α = 0.85) and the PCS (α = 0.86), both of which were adapted for Chinese adolescents. Parent (n = 6) and teacher (n = 5) interviews were analyzed thematically (Braun & Clarke).
resultsCompared with controls, the MBCT group showed greater reductions in perceived stress and psychosomatic symptoms at post-test and two-month follow-up (Group×Time, p < .001; partial η²≈0.32-0.63). Mean reductions exceeded a conventional 0.5 SD benchmark, supporting applied relevance alongside statistical significance. Qualitative analysis yielded six themes that contextualized change: (1) reduced stress reactivity, (2) improved emotion regulation and self-awareness, (3) strengthened coping, (4) enhanced peer/family communication, (5) better classroom engagement, and (6) conditions for maintenance (practice dose, prompts, family/teacher supports).
conclusionsSchool-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.
