Cumulative lifetime trauma exposures in a nationally representative prison sample: findings from the mental health and substance use disorders prevalence survey.
Article in Social psychiatry and psychiatric epidemiology, 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
backgroundTrauma exposure is a driver of poor health, mental health, social and economic outcomes with a dose-response relationship between number of types of exposures and worse outcomes. This study explores the trauma exposure histories of individuals in prison, a population with elevated rates of chronic medical and mental health conditions.
methodsUsing data from the Mental and Substance Use Disorders Prevalence Study (MDPS), we calculated weighted estimates of the lifetime prevalence of six types of trauma exposures as well as risk for experiencing multiple or cumulative trauma exposures for a nationally representative prison sample. We compare these estimates to estimates for those in the community while controlling for sociodemographic characteristics.
resultsThe nationally representative prison sample was 93% male and 60% people of color (29% Black, 31% Hispanic). The prison sample had three times the odds of the community sample of experiencing any type of trauma exposure, holding demographic characteristics constant. Moreover, the prison sample had twice the odds of experiencing multiple exposures.
conclusionsMultiple, cumulative lifetime trauma exposures are characteristic of the trauma histories of people in prison in the U.S. Systems serving incarcerated and formerly incarcerated populations should look to the abundance of research knowledge about trauma intervention approaches that support physical and mental health and can be adapted to correctional systems.
