A metacognitive mediation model of sleep quality: the roles of rumination and anxiety sensitivity in a community sample.
Article in BMC 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
objectiveMetacognitive theory suggests that maladaptive beliefs about thinking are associated with the cognitive attentional syndrome (CAS), which is characterized by repetitive negative thinking and heightened threat monitoring. This study examined a dual-mediation model in which rumination and anxiety sensitivity were tested simultaneously as mediators of the relationship between metacognitive beliefs and sleep quality in a nonclinical sample.
methodsA total of 346 Iranian adults (18-60 years) completed validated self-report measures of metacognitive beliefs, rumination, anxiety sensitivity, and sleep quality. Structural equation modeling (SEM) with bias-corrected bootstrapping (2,000 resamples) was used to test the hypothesized model.
resultsThe model demonstrated acceptable fit to the data (CFI = 0.96, RMSEA = 0.074). Metacognitive beliefs were not significantly associated with sleep quality after including the mediators. However, significant indirect effects were observed through rumination (β = 0.32, 95% CI [0.20, 0.40]) and anxiety sensitivity (β = 0.28, 95% CI [0.17, 0.37]). The model explained 50% of the variance in sleep quality.
conclusionsThe findings indicate that metacognitive beliefs are statistically associated with poorer sleep quality indirectly through rumination and anxiety sensitivity in a community sample. These results support the value of examining transdiagnostic cognitive-emotional processes in sleep research. Due to the cross-sectional design and reliance on self-report measures, causal inferences cannot be drawn. Future longitudinal and experimental studies are needed to clarify the temporal relationships and clinical utility of these pathways.
