Prospective investigation of positive psychotic symptoms, dissociative symptoms, and metacognitive dysfunctions in a non-clinical population.
Article in Scientific reports, 2025. 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
The frequent co-occurrence of positive psychotic and dissociative symptoms in both clinical and non-clinical populations underscores the importance of understanding their interplay for early intervention. However, their longitudinal dynamics and shared risk factors in non-clinical individuals are poorly understood. This prospective study investigated the reciprocal relationship between positive psychotic and dissociative symptoms and the role of metacognitive dysfunction in 2,360 adults without psychiatric diagnoses (age 18-65). Participants completed online questionnaires at baseline and at six months, reporting levels of positive psychotic and dissociative symptoms, maladaptive metacognitive beliefs and metacognitive functioning. Longitudinal structural equation modelling, controlling for autoregressive effects, assessed the variables' cross-lagged associations. Results showed that baseline positive psychotic symptoms predicted dissociative symptoms at six months, and vice versa. Maladaptive metacognitive beliefs (lower cognitive self-consciousness) and poorer metacognitive functioning (self-reflectivity) at baseline predicted increased dissociative symptoms, but not positive psychotic symptoms, at six months. Higher baseline dissociative symptoms reciprocally predicted poorer metacognitive functioning at six months. Our findings support the mutual influence between positive psychotic and dissociative symptoms, and the specific association of metacognitive factors with dissociative symptoms, independent of co-occurring positive psychotic symptoms. Future research should extend these findings with longer follow-up periods and in clinically diverse groups.
