Problem Management Plus for improving mental health among earthquake-affected individuals in Türkiye: pilot randomised controlled trial.
Article in BJPsych open, 2026. 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
backgroundEarthquakes present significant threats to community mental health, yet post-disaster resource limitations and high demand restrict access to care. The 2023 Türkiye-Syria earthquakes affected millions, increasing psychological problems and highlighting the urgent need for scalable interventions.
aimsThis study assessed (a) the feasibility of procedures prior to a fully powered randomised controlled trial (RCT) and (b) the potential effectiveness of Problem Management Plus (PM+), a scalable psychological intervention, in reducing common mental health problems among Turkish earthquake survivors.
methodA two-arm, single-blind pilot RCT was conducted with survivors residing in temporary housing in Türkiye. Participants were randomly allocated (1:1) to PM+ (
resultsRecruitment, retention (74%) and treatment adherence (79%) supported feasibility. At post-assessment, PM+ showed greater reductions than E-CAU across all outcomes: PHQ-9 (adjusted mean difference -5.91, 95% CI -8.23 to -3.58), PSYCHLOPS (-6.94, -8.88 to -5.01), WHODAS 2.0 (-8.77, -12.50 to -5.03), K-10 (-9.66, -13.35 to -5.97), GAD-7 (-4.31, -6.39 to -2.24) and PCL-5 (-18.72, -25.97 to -11.47). At follow-up, improvements remained significant for psychological distress and self-identified problems.
conclusionsFindings provide preliminary evidence that PM+ is a feasible and potentially effective intervention for alleviating common mental health problems among Turkish earthquake survivors.
