Perceived Stress Scale: Psychometric Validation in Spanish University Nursing Students and Applications for Mental Health.
Article in Journal of psychiatric and mental health 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
backgroundNursing students-including those specializing in mental health and psychiatric care-as well as practicing psychiatric nurses frequently experience elevated levels of psychological stress. Such stress can adversely affect their academic performance, overall well-being, and future professional development. Accurate assessment of perceived stress is essential for identifying individuals at risk and for designing targeted support strategies.
aimsThis study aimed to examine the psychometric properties of the 14-, 10-, and 4-item versions of the Perceived Stress Scale, evaluating their validity, reliability, measurement invariance, and diagnostic utility using salivary cortisol as a physiological benchmark.
methodsParticipants completed the Spanish version of the Perceived Stress Scale, the Sense of Coherence-13 scale, and provided morning salivary cortisol samples. Confirmatory factor analysis, internal consistency assessment, measurement invariance testing across demographic subgroups, hypothesis testing, and Area Under the Curve-Receiver Operating Characteristic analysis using cortisol as a criterion standard were performed.
resultsThe Perceived Stress Scale (14- and 10-item format) demonstrated a stable two-factor structure, high internal consistency, and measurement invariance across gender, educational level, employment status, and living arrangements. It also showed correlations with Sense of Coherence-13 scale scores. While it demonstrated moderate sensitivity relative to physiological stress (salivary cortisol), its specificity was lower.
conclusionsThe Perceived Stress Scale-10 emerged as the most psychometrically robust and practical version for assessing perceived stress. Its use in educational and mental health settings may support early identification of individuals under high stress and facilitate the implementation of targeted interventions to promote well-being.
