A teacher-led classroom intervention in an area of Mexico experiencing community violence: A controlled mixed-method feasibility study.
Article in PloS one, 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
objectivesWe aimed to explore the effectiveness of a daily ten-minute teacher-led group thought field therapy stress-reduction intervention on middle-school adolescents residing in an area experiencing high levels of interpersonal and community violence. We hypothesized that it would lead to a reduction of trauma symptoms and improve grades in reading and math.
methodsIn this double-masked feasibility study, adolescents in one school received a daily teacher-led thought field therapy intervention, and children in a different school served as an active waitlist group and received the same amount of time in a daily unguided drawing activity. The schools were geographically distant to prevent cross-contamination.
resultsDue to differences between groups in PTSD and academic performance prior to intervention, differences within each school's scores over time were calculated and compared to each other for indirect assessment of effect. PTSD scores at the treatment school showed no lasting change at five months, while the control school showed moderate improvement. Adolescents in the treatment group demonstrated large improvements in both reading and math. Adolescents in the control group demonstrated moderate decrease in math, and no change in reading.
conclusionsPreliminary evidence gained in this study suggests that a teacher-led ten-minute group thought field therapy exercise might assist adolescents' learning in reading and math. However, in an area experiencing ongoing interpersonal and community violence, a more multicomponent approach with longer periods of intervention, caretaker involvement and individual therapy for those who might benefit from it, may be needed.
