Screening for posttraumatic stress disorder (PTSD) in Mozambique: Validation of the Primary Care Posttraumatic Stress Disorder Screen for Diagnostic and Statistical Manual fifth edition (PC-PTSD-5).

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
objectiveThe confluence of conflict-, climate-, and public health-related emergencies in Mozambique increases the risk of posttraumatic stress disorder (PTSD). Few brief screening tools for PTSD have been validated in low- and middle-income countries. We aimed to validate the five-item Primary Care PTSD Screen for the
methodThis study recruited 957 participants who completed the Mini-International Neuropsychiatric Interview-Plus (MINI-Plus) and PC-PTSD-5, a convenience sample from primary and tertiary care settings in Maputo, Mozambique. Participants were administered a diagnostic interview for psychiatric disorders and the PC-PTSD-5 screening tool. We evaluated the criterion validity of the PC-PTSD-5 concerning the MINI-Plus diagnosis of PTSD, the internal construct validity and reliability using confirmatory factor analysis and Kuder-Richardson 20 (KR-20), discriminant validity of the PC-PTSD-5 in comparison to other common mental disorder and suicide risk screening tools, and measurement invariance of selected cutoffs by age, sex, and comorbidity.
resultsInternal consistency of the PC-PTSD-5 was high (KR-20 = 0.837), and confirmatory factor analysis suggested that a single PTSD factor fits the data well. PC-PTSD-5 items were moderately correlated with other psychiatric symptoms. Criterion validity analyses revealed that a cutoff score of 3 provided high specificity (0.833) and moderate sensitivity (0.673). This cutoff score performed optimally across age and gender; however, a cutoff score of 2 was preferred if the participant had no psychiatric comorbidities.
conclusionScreening with the PC-PTSD-5 may facilitate case detection and linkages to appropriate treatment for individuals affected by potentially traumatic events in Mozambique. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
