The impact of stress on personality state expressions.
Article in Communications psychology, 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
Who we are at any given moment depends not only on our psychological dispositions but also the situational forces we experience. Here, we explore how stress - an intrapsychic situational force - impacts momentary personality expression. In Study 1 (N = 792), we experimentally induced stress, showing that the experience of stress is causally related to lower levels of state Openness, Conscientiousness, Extraversion, Agreeableness and higher levels of state Neuroticism. In Study 2 (N = 713; 17,853 observations), we used experience sampling to capture naturally occurring stress and show that stress is associated with lower levels of state Extraversion and Agreeableness, and higher levels of state Neuroticism and Openness in everyday situations. Notably, across both studies, the associations between stress and personality state expressions are largely robust when accounting for momentary affect. Together, our work highlights stress as a distinct and dynamic driver of personality state variability in everyday life.
