Somatic symptoms among young adults: an observational study examining the roles of trauma type and psychological distress.
Observational study in BMC psychology, 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
backgroundThis study extends previous research examining the interplay between trauma and somatic symptoms by focusing on trauma type (i.e., whether the trauma was interpersonal in nature [e.g., assault, sexual violence, combat] or not) and the extent to which psychological distress accounts for these associations. Additionally, we novelly focus on clusters of somatic symptoms.
methodsA sample of predominantly Hispanic/Latinx young adults (n = 214) completed a series of brief validated questionnaires assessing demographics, stressful life events (Stressful Life Events Screening Questionnaire - revised), somatic symptoms (Patient Health Questionnaire - 14), and psychological distress (Patient Health Questionnaire - 4) as part of an online survey. Data were first analyzed using linear regression, followed by structural equation modeling to estimate indirect effects, with bootstrapping used to generate confidence intervals.
resultsResults support a significant indirect effect of interpersonal trauma (IP) on somatic symptoms through psychological distress. While both IP and psychological distress contributed to cardiopulmonary and pain/fatigue clusters, gastrointestinal symptoms were accounted for by psychological distress. Exploratory analyses revealed unique associations by gender, with partial mediation of associations between IP and somatic symptoms by psychological distress observed more clearly in women.
conclusionsThe present study extends extant research demonstrating that greater exposure to interpersonal trauma exposure is significantly and strongly associated with increased somatic symptoms, psychological distress partially accounts for these associations. With replication, these findings inform theoretical frameworks of the psychological underpinnings of somatic symptom development and can be used to foster advancements in patient care.
