Abstract
The association and overlap between psychotic and dissociative phenomena have been increasingly recognized. Previous studies found that psychotic symptoms are closely associated with post-traumatic and dissociative symptoms and that these trauma-related phenomena may mediate the relationship between trauma and psychotic symptoms. It remained less explored which specific post-traumatic and dissociative symptom clusters are particularly associated with psychotic symptoms. This cross-sectional study used a data-driven approach (network analysis) to explore the associations among different psychotic and post-traumatic/dissociative symptom clusters in an online convenience predominantly female sample (N = 468)(59.2% had ever seen a psychiatrist). Participants completed well-established multidimensional measures that assessed different symptom clusters of psychosis, dissociation, and PTSD. In addition, multiple mediation analysis was conducted to examine which post-traumatic/dissociative symptoms could mediate the relationship between childhood and adulthood trauma and different psychotic symptoms. Our results confirmed previous findings that PTSD and dissociative symptoms are closely associated with psychotic symptoms. More importantly, both data-driven and multiple mediation analysis results indicated that identity dissociation was particularly associated with perceptual anomalies and bizarre experiences, while emotional constriction was particularly associated with negative symptoms. It is important to screen for trauma and dissociation and provide trauma-and dissociation-informed care when working with people at risk of or experiencing psychosis. Further longitudinal studies using more representative samples are needed.

Abstract
ABSTRACT Dissociative identity disorder (DID) has historically been one of the most controversial topics in the study of psychopathology. Building on a previous review of empirical research on DID from 2000 to 2010, the present review examined DID research from 2011 to 2021. The research output included 56 case studies and 104 empirical studies. Within the empirical studies, approximately 1354 new cases of DID emerged, which resulted in an average samples of approximately 20. Reanalysis of previous samples was standard in the literature with only 40% of reported cases being new. Studies emerged from dozens of countries across the world, but the majority of cases were from Western counties, especially the United States. Diagnosis primarily relied upon validated measures, but 74% of all new cases came from six research groups. Overall, research on DID is steady but methodologically limited in ways that make generalization, especially about etiology, difficult.

Delusional beliefs in adolescents with anorexia nervosa, obsessive-compulsive disorder, or first-episode psychosis: A comparative study. Psychiatry Res 2023; 328:115490. [PMID: 37748237 DOI: 10.1016/j.psychres.2023.115490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 09/13/2023] [Accepted: 09/21/2023] [Indexed: 09/27/2023]
Abstract
Delusional thinking is a key symptom of first-episode psychosis (FEP), but it has also been studied in obsessive-compulsive disorder (OCD) and anorexia nervosa (AN). This study aimed to analyze the psychometric properties of the Brown Assessment of Beliefs Scale (BABS) in a sample of adolescents diagnosed with a FEP, AN, or OCD, and to compare delusional thinking among the three samples. The sample comprised 60 patients in three groups of 20 diagnosed with OCD, AN, or FEP. Participants underwent assessment by diagnostic interview, the BABS scale, and a measure of depressive symptomatology. Specific instruments were also used to assess the main symptomatology of each disorder. The BABS had good internal consistency, and high validity and reliability. The OCD group scored significantly lower than the other two groups in all scale items except for items 4 (fixation of ideas), 6 (insight), and 7 (delusions of reference). A significant difference only existed between the AN and FEP groups for item 7 (delusions of reference). The BABS scale is a valid and reliable tool for assessing delusionality in adolescents diagnosed with OCD, AN, or FEP, with evidence of marked differences between the disorders. Assessing these symptoms could influence management, helping to improve treatment adherence and prognosis.
