The Traumatic Event Checklist for North Korean Defectors.
Article in Psychiatry investigation, 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
objectiveThis study aimed to develop and validate a trauma checklist specifically designed to capture the complex and culturally unique potentially traumatic events (PTEs) experienced by North Korean defectors (NKDs), in alignment with International Classification of Diseases, 11th Revision criteria that distinguish posttraumatic stress disorder (PTSD) from complex PTSD (cPTSD).
methodsA cross-sectional secondary data analysis was conducted using online survey data from 520 NKDs. Participants were randomly divided into two groups (n=260 each) for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). A preliminary 22-item PTE checklist was refined through factor analysis and reliability testing. Criterion validity was assessed using the Depression and Somatic Symptom Scale and World Health Organization of Life Assessment Instrument Bref. Statistical analyses were performed using SPSS 28.0 and AMOS 28.0.
resultsEFA identified a four-factor model: "death and life-threatening events," "interpersonal violence and discrimination," "violence by public authorities," and "family dissolution"-comprising 17 refined items. CFA confirmed a good model fit (RMSEA=0.059, GFI=0.930, CFI=0.930). Internal consistency for the total scale was high (Cronbach's α=0.830), with acceptable reliability across most subscales. The checklist demonstrated strong criterion validity with depression, somatic symptoms, and quality of life indices.
conclusionThe revised PTEs checklist is a valid and reliable screening tool that reflects NKDs' unique trauma experiences across the pre-, peri-, and post-migration phases. Its combined use with the International Trauma Questionnaire is recommended for comprehensive trauma assessment and tailored intervention planning.
