1 · What the graph read from it

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.

2 · The registry

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

backgroundHaiti is experiencing a severe humanitarian crisis characterised by political instability and economic and security hardship. These adversities contribute to significant mental health challenges, which are also exacerbated by poor access to psychological support due to a shortage of specialised professionals. Problem Management Plus (PM+), a scalable and low-intensity intervention developed by the World Health Organization, is based on a task-sharing approach to address the treatment gap by training non-specialist helpers to provide psychosocial support.

aimsThis study aimed to explore the implementation process of PM+ in Haiti, focusing on the barriers and facilitators that influenced its delivery. Specifically, the study focused on understanding the contextual factors affecting intervention accessibility, participant experiences and potential adaptations to enhance its effect.

methodA qualitative study was conducted across three Haitian cities, where trained helpers delivered PM+. Data were collected through the PSYCHLOPS tool with end-users and via cognitive interviews with stakeholders. Thematic analysis was conducted incorporating Lund's social determinants of mental health model and Bronfenbrenner's ecological systems theory to interpret findings.

resultsSixteen end-users and five stakeholders participated in the study. Key barriers to implementation and its success mainly included economic constraints and safety concerns. Facilitating factors included strong community engagement, adaptive implementation strategies (such as flexible scheduling, remote supervision and culturally responsive adjustments), alongside strong organisational support. End-users described substantial difficulties in managing everyday problems and emotional distress, as reported during pre-intervention qualitative assessments.

conclusionsPM+ appeared feasible in the Haitian context from an implementation perspective; however, its implementability depends on cultural adaptations, economic considerations and sustained support for facilitators. Addressing systemic barriers and integrating task-sharing interventions within existing health structures could enhance the long-term impact.
