Personality Traits and Psychological Well-Being: Association Within the "Seguimiento Universidad de Navarra" (SUN) Cohort.
Article in Personality and mental health, 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
Psychological well-being (PWB) is a core component of mental health influenced by personality; however, most prior research focused on subjective well-being and normal-range personality traits. Less is known about the longitudinal role of maladaptive personality traits in shaping eudaimonic well-being. This study examined prospective associations between maladaptive personality domains and subsequent PWB in the SUN cohort. Personality traits were assessed at the 16-year follow-up using the Personality Inventory for DSM-5 Abbreviated Form (PID-5-BF). PWB was evaluated 2 years later using Ryff's 29-item scale. All domains were analyzed as continuous variables in multivariable linear regression models with mutual adjustment. Among 2080 participants (56.9% women, mean age 57 ± 10.9 years), higher levels of detachment (β: -2.43; 95% CI: -2.77, -2.09), negative affect (β: -1.09; 95% CI: -1.38, -0.80), psychoticism (β: -0.76; 95% CI: -1.21, -0.30) and disinhibition (β: -0.52; 95% CI: -0.93, -0.11) were prospectively associated with lower PWB, whereas antagonism showed a positive association (β: 0.76; 95% CI: 0.36, 1.17). Detachment was consistently associated with lower scores across all six PWB dimensions, negative affect and psychoticism showed selective inverse associations with several PWB dimensions, and disinhibition showed an inverse association for autonomy. Nevertheless, antagonism displayed positive associations with environmental mastery, purpose in life, and self-acceptance. In conclusion, maladaptive personality traits are prospectively associated with PWB, with domain-specific patterns, highlighting the importance of a multidimensional perspective when examining personality-PWB relationships.
