Who Are People with Psychosis Delusional about? A Study of Social Agents in the Phenomenology of Delusions.
Article in Psychopathology, 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
introductionDelusions frequently involve strong beliefs about, or interactions with, illusory social agents. Although such agents have been systematically described in hallucinations, few studies have investigated their nature and identity in delusions.
methodsWe identified 205 electronic mental health records describing the content of delusions from the Clinical Record Interactive Search platform at South London and Maudsley NHS Foundation Trust. Delusional content was classified as non-social, implicitly social, or explicitly social. Descriptions of illusory social agents from explicitly social delusions were extracted and categorized using an upward coding analysis. A hierarchical cluster analysis identified distinct groupings of illusory social agents.
resultsMost delusions (83.4%) contained explicit references to illusory social agents. Across 238 instances, we identified 220 distinct agent identities, with a mean of 1.17 agents per record. The majority were humans (85.1%), most often identified as family members (31.0%), followed by acquaintances (17.2%), religious figures (13.2%), unnamed persons (12.8%), professionals (11.8%), and cultural figures (10.9%). Hierarchical clustering revealed two distinct groups: one including socially proximate agents and the other more socially distant agents. These findings indicate a social gradient in delusions.
conclusionSocial content predominates in delusions, with patients experiencing delusions about socially closer individuals more frequently. We discuss the extent to which social gradient may not be unique to delusional misidentification syndromes but may instead represent a general feature of delusions. Better characterization of social agents in delusions could inform mechanistic accounts of these symptoms and, in clinical practice, guide family support and risk assessment.
