Cognitive Flexibility as a Mediator Between Mentalization and Symptom Severity in Generalized Anxiety Disorder.
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
objectiveMentalization and cognitive flexibility are key constructs in contemporary models of anxiety psychopathology; however, their interrelationship in clinically diagnosed generalized anxiety disorder (GAD) remains insufficiently delineated. This study aimed to examine whether cognitive flexibility mediates the association between mentalization and anxiety severity.
methodsIn this cross-sectional study, 110 patients with GAD, diagnosed according to DSM-5 criteria, completed the Mentalization Scale, Cognitive Flexibility Inventory, and Generalized Anxiety Disorder-7. Associations were assessed using Pearson correlation analyses, and mediation was examined using bias-corrected bootstrapping (5,000 resamples).
resultsCognitive flexibility was moderately negatively associated with GAD severity (r=-0.421, p<0.001), whereas mentalization showed a weaker but significant negative association (r=-0.293, p=0.002). In addition, mentalization and cognitive flexibility were strongly positively correlated (r=0.636, p<0.001). Mediation analysis revealed a significant indirect effect of mentalization on anxiety severity through cognitive flexibility (B=-0.083, 95% confidence interval [-0.132, -0.042], p=0.001), while the direct effect was not statistically significant.
conclusionCognitive flexibility significantly mediated the association between mentalization and anxiety severity; however, given the cross-sectional design, this finding should be interpreted as statistical mediation rather than evidence of a causal mechanism. Although causal inferences cannot be established due to the cross-sectional design, cognitive flexibility may represent a clinically relevant target for reducing anxiety symptoms. Future longitudinal and interventional studies are warranted to clarify the directionality and clinical implications of these findings.
