State violence, protest suppression, and trauma outcomes: a scoping review of cumulative exposure across different political contexts.
Review in European journal of psychotraumatology, 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
backgroundState violence directed at protest movements represents a recurrent source of trauma exposure, yet research examining its psychological consequences remains fragmented across disciplines, exposure modalities, and political contexts.
objectiveThis scoping review synthesises evidence on protest suppression and state violence to examine how repressive practices function as pathways to trauma-related outcomes across diverse settings.
methodEligible sources, including peer-reviewed empirical studies, systematic and scoping reviews, and institutional or policy documents published between January 2016 and February 2026, were mapped across six exposure domains: population-level unrest climates, protesters' direct exposure to police violence, repression technologies and injury pathways, soft repression and prolonged threat, mediated and spillover exposure, and exile and transnational repression. The evidence was synthesised narratively, with interpretation taking account of source type, study design, and the directness of mental health measurement.
resultsAcross the six exposure domains, findings associate protest suppression with post-traumatic stress symptoms, depression, anxiety, suicidality, and chronic hypervigilance. Evidence indicates that psychological harm extends beyond direct encounters with violence and is shaped by cumulative insecurity, digital mediation, durational threat, and cross-border coercion. Taken together, the literature presents repression as a population-level and multi-sited exposure with wider psychological effects.
conclusionsProtest suppression can operate as a cumulative mechanism of trauma production extending beyond a discrete event. Recognising indirect, mediated, and transnational exposure has implications for trauma-informed clinical practice, policy responses, and future interdisciplinary research addressing contemporary forms of political violence.
