A latent profile analysis of positive psychotic symptoms and dissociative symptoms in the general population: their associations with childhood trauma and outcomes.
Article in Social psychiatry and psychiatric epidemiology, 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
purposePsychosis and dissociation are inter-correlated syndromes. As they are both multifaceted constructs, individuals experiencing positive psychotic and dissociative symptoms may have heterogeneous presentations of co-occurring symptomatology. This study aimed to identify phenotypes of individuals with varying degrees of these co-occurring symptoms in the general population, while also examining the impact of childhood trauma and prospective emotional and functional outcomes associated with these phenotypes.
methodParticipants were recruited from the general population through diverse means. At baseline and six months after, adults (age 18-65) were assessed for positive psychotic symptoms, dissociative symptoms, depression, anxiety, and functioning using an online survey. Childhood trauma was assessed at baseline only. Distinct subgroups were estimated by latent profile analysis, with childhood trauma examined as predictor of the profiles. The identified profiles were compared on emotional and functional outcomes at both timepoints.
resultsThe community sample consisted of 2,958 individuals (mean age = 34.69; 72.5% female). Four distinct profiles were identified - 'low overall', 'moderate (hallucinatory)', 'moderate (dissociative)', and 'high overall'. Emotional/sexual abuse and physical neglect notably differentiated the 'low overall' profile from the other three profiles, with sexual abuse specifically linked to the 'high overall' and 'moderate (hallucinatory)' profiles. The 'high overall' and 'moderate (dissociative)' profiles exhibited persistent elevated depression across timepoints than the other profiles.
conclusionsDistinct profiles of varying levels of co-occurring positive psychotic and dissociative symptoms were identified in the general population. The implications for early identification and intervention of these commonly co-occurring symptoms are discussed.
