Despite growing interest in the phenomenology of delusions psychosis, at present little is known about their content and evolution over time, including whether delusion themes are consistent across episodes.
During a psychotic episode, patients frequently suffer from severe maladaptive beliefs known as delusions. Despite the abundant literature investigating simple presence or absence of these beliefs, there exists little detailed knowledge regarding their actual content and severity at onset illness.This study reports on delusions during initiation indicated treatment for first-episode psychosis (FEP).Data were systematically collected sample 636 entering catchment-based early intervention...
Abstract Background There exist few direct studies of delusional content in psychosis across geo-cultural contexts, especially those which treatment protocols and measures are comparable. To directly examine an illness outcome that is potentially culturally mediated, this study investigated the baseline presentation longitudinal trajectory delusions first-episode (FEP) 2 similar settings Montréal (Canada) Chennai (India). Study Design Patients entering early intervention program for FEP (N =...
Hallucinations are a core feature of psychosis, and their severity during the acute phase illness is associated with range poor outcomes. Various clinical sociodemographic factors may predict hallucinations other positive psychotic symptoms in first episode psychosis (FEP). Despite this, precise at presentation to an early intervention service have not been extensively researched. Through detailed interviews chart reviews, we investigated predictors 636 minimally-medicated patients who...

Objective: Psychotic disorders are highly heterogeneous. Understanding relationships between symptoms will be relevant to their underlying pathophysiology. We apply dimensionality-reduction methods characterize the patterns of symptom clustering and how clusters relate one another.Methods: analyzed publicly-available data from 153 participants diagnosed with schizophrenia or schizoaffective disorder (fBIRN Data Repository Consortium for Neuropsychiatric Phenomics), as well 636 first-episode...
Abstract Background During a psychotic episode, patients frequently suffer from severe maladaptive beliefs known as delusions. Despite the abundant literature investigating simple presence or absence of these beliefs, there exists little detailed knowledge regarding their actual content and severity at onset illness. Investigating delusions in early clinical samples is critical, because relatively young, treatment-naïve presentations are less likely to be confounded by effects long-term...
Background: Despite growing interest in the phenomenology of delusions psychosis, at present there is little known about their content and evolution over time – including whether delusion themes are consistent from one episode to next. Method: We utilized systematically collected longitudinal data 636 consenting participants followed naturalistically an early intervention service for psychosis. identified thematic severity (marked by scores ≥ 3 using Scale Assessment Positive Symptoms;...
