The efficacy of a PERMA-based intervention on PTSD symptoms and well-being in newly qualified operating room nurses: a quasi-experimental study.
Article in BMC nursing, 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
backgroundNewly qualified operating room nurses suffer from common workplace verbal violence and occupational stress, increasing their risk of Post-Traumatic Stress Disorder (PTSD). However, evidence regarding the efficacy of the PERMA model (Positive Emotion, Engagement, Relationships, Meaning, Achievement) in reducing PTSD symptoms in this cohort remains limited.
methodsThis preliminary, quasi-experimental study included two phases: a cross-sectional survey of 178 operating room nurses to assess probable PTSD prevalence, followed by an 8-week PERMA-based intervention for 27 nurses who screened positive for probable PTSD. The PTSD Checklist-Civilian Version (PCL-C) and Campbell Index of Well-being (IWB) were measured at baseline, post-intervention, and 3-month follow-up.
resultsThe prevalence of probable PTSD was 19.0%. All nurses in the probable PTSD group reported verbal violence exposure; specific occupational fears were significant independent predictors of probable PTSD. A dose-response relationship existed between stressor count and probable PTSD risk (OR = 7.426, 95% CI: 3.704-14.890). The intervention was associated with a significant reduction in PCL-C scores (p = 0.007), while IWB scores showed no significant change.
conclusionsNewly qualified operating room nurses are exposed to probable PTSD risk, closely linked to verbal violence and occupational stressors. A PERMA-based intervention was associated with a reduction in their PTSD symptoms, highlighting the need to incorporate targeted psychological support and anti-workplace violence policies to protect this workforce. As a preliminary study, these findings should be confirmed in a larger, definitive randomized controlled trial.
