Reducing anxiety and depression in Chinese adolescents through group behavioral activation: a pilot study with school-based implementation.
Article in Child and adolescent psychiatry and mental health, 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
backgroundAnxiety and depression are increasingly prevalent public health concerns among adolescents. Group Behavioral Activation Therapy (GBAT), a structured school-based intervention, has shown promise as a potential approach for alleviating these conditions.
methodsThis quasi-experimental trial evaluated the efficacy of school-implemented GBAT in reducing anxiety and depressive symptoms among Chinese adolescents. Participants (N = 139; aged 12-17 years; 44.6% male) were assigned to either a GBAT group (n = 72) or a waitlist control group (n = 67). The GBAT protocol consisted of eight weekly 90-minute sessions. Outcomes were assessed at baseline, post-intervention, and 3-month follow-up using the Screen for Child Anxiety Related Emotional Disorders (SCARED) and the Depression Self-Rating Scale for Children (DSRSC).
resultsA total of 93.06% of students completed all eight GBAT sessions. Post-intervention SCARED scores decreased significantly, t (135) = 2.44, MD = 4.20, 95% CI [0.79, 7.60], p = 0.016, Cohen's d = 0.42. Linear mixed-model analysis revealed a significant group effect (F (1,397) = 10.60, p = 0.001), indicating lower anxiety scores in the GBAT group compared with the waitlist control. A significant time effect was also observed, F (1,397) = 7.64, p < 0.001. At 3-month follow-up, GBAT maintained significant improvement in anxiety (SCARED: MD = 8.69, 95% CI [3.58, 13.80], p < 0.001 Cohen's d = 0.82) and depressive symptoms (DSRSC: MD = 2.28, 95% CI [0.10, 4.46], p = 0.037, Cohen's d = 0.43), indicating moderate to large effect sizes.
conclusionsThese preliminary findings suggest that GBAT may be a promising primary prevention strategy for adolescent mental health. This study provides a foundation for future research exploring its potential integration into school-based mental health frameworks.
