Selective aggregation of self-disorders in first-treatment DSM-IV schizophrenia spectrum disorders.

Abstract Converging evidence indicates that self-disorders (SDs) selectively aggregate in schizophrenia spectrum conditions. The aim of this study was to test the discriminatory power of SDs with respect to schizophrenia and nonschizophrenia spectrum psychosis at first treatment contact. SDs were assessed in 91 patients referred for first treatment through the Examination of Anomalous Self-experience (EASE) instrument. Diagnoses, symptoms severity, and function were assessed using the Structural Clinical Interview for the DSM-IV, Structured Clinical Interview for the Positive and Negative Syndrome Scale, Calgary Depression Scale for Schizophrenia, Young Mania Rating Scale, and Global Assessment of Functioning–Split Version. Most patients found it highly relevant to talk about SDs. EASE total score critically discriminated between schizophrenia, bipolar psychosis, and other psychoses. The EASE total score was the only clinical measure that showed a significant and robust association with the diagnosis of schizophrenia. Systematic exploration of anomalous self-experiences could improve differential diagnosis in first-treatment patients.

Suicidality in first episode psychosis is associated with insight and negative beliefs about psychosis

INTRODUCTION Suicidal behaviour is prevalent in psychotic disorders. Insight has been found to be associated with increased risk for suicidal behaviour, but not consistently. A possible explanation for this is that insight has different consequences for patients depending on their beliefs about psychosis. The present study investigated whether a relationship between insight, negative beliefs about psychosis and suicidality was mediated by depressive symptoms, and if negative beliefs about psychosis moderated the relationship between insight and suicidality in patients with a first episode of psychosis (FEP). METHOD One hundred ninety-four FEP-patients were assessed with a clinical interview for diagnosis, symptoms, functioning, substance use, suicidality, insight, and beliefs about psychosis. RESULTS Nearly 46% of the patients were currently suicidal. Depressive symptoms, having a schizophrenia spectrum disorder, insight, and beliefs about negative outcomes for psychosis were independently associated with current suicidality; contradicting a mediating effect of depressive symptoms. Negative beliefs about psychosis did not moderate the effect of insight on current suicidality. CONCLUSION The results indicate that more depressive symptoms, higher insight, and negative beliefs about psychosis increase the risk for suicidality in FEP-patients. The findings imply that monitoring insight should be part of assessing the suicide risk in patients with FEP, and that treating depression and counteracting negative beliefs about psychosis may possibly reduce the risk for suicidality.

Anomalous self-experiences contribute independently to social dysfunction in the early phases of schizophrenia and psychotic bipolar disorder.

BACKGROUND Psychotic disorders are associated with significant social dysfunction. Anomalous self-experiences (ASE) present in psychotic disorders could contribute to social dysfunction. AIM To investigate if ASE contribute to social dysfunction in the early phases of psychotic disorders after controlling for factors related to social functioning including diagnoses. METHODS ASE were assessed by means of the EASE (Examination of Anomalous Self-Experience) in 76 patients referred to their first adequate treatment for schizophrenia or psychotic bipolar disorder. Diagnoses, symptom severity, and functioning were assessed using the Structured Clinical Interview for the Positive and Negative Syndrome Scale, Calgary Depression Scale for Schizophrenia, Premorbid Adjustment Scale, Global Assessment of Functioning--Split Version, and Social Functioning Scale. Neurocognitive assessments included measures of psychomotor speed, working memory, executive and memory functions. Duration of untreated psychosis was also assessed. RESULTS High levels of ASE were significantly associated with poorer social functioning in the early phases of schizophrenia and psychotic bipolar disorder also after correcting for diagnosis. CONCLUSION This study demonstrates the significance of ASE for social dysfunction in patients with psychotic disorders, and contributes to the understanding of the complexity of illness-related factors that affect social functioning.

Anomalous self-experience and childhood trauma in first-episode schizophrenia

BACKGROUND Anomalous self-experiences (ASEs) are viewed as core features of schizophrenia. Childhood trauma (CT) has been postulated as a risk factor for developing schizophrenia. AIM The aim of this study is to investigate the relationships between CT, depression and ASEs in schizophrenia. METHOD ASEs were assessed in 55 patients in the early treated phases of schizophrenia using the Examination of Anomalous Self-Experience (EASE) instrument. Data on CT were collected using the Childhood Trauma Questionnaire, short form (CTQ-SF). This consists of 5 subscales: physical abuse, sexual abuse, emotional abuse, emotional neglect, and physical neglect. Assessment of depression was based on the Calgary Depression Scale for Schizophrenia (CDSS). RESULTS We found significant associations between EASE total score and CTQ total score and between EASE total score and emotional neglect subscore in women, but not men. We also found significant associations between CDSS total score and CTQ total score and between CDSS total score and emotional abuse, emotional neglect, and physical neglect subscores in women, but not men. In men we did not find any significant associations between EASE total score, CDSS total score and any CTQ scores. CONCLUSION CT was significantly associated with higher levels of ASEs in women in the early treated phases of schizophrenia, but not in men. This again associated with an increase in depressive symptoms.

Social dysfunction in first-episode psychosis and relations to neurocognition, duration of untreated psychosis and clinical symptoms

Signs of social dysfunction are present early in the course of psychotic disorders. There is a lack of knowledge about how premorbid function, illness history, psychotic symptoms and neurocognitive characteristics are related to social function in patients with first episode psychosis (FEP). The relationship between these factors could provide important information about the psychopathology underlying social dysfunction and have implications for future prevention and treatment efforts. Our objective is to identify early predictors of social functioning in patients with FEP. We examined 166 patients and 166 age- and gender-matched healthy controls (HC). We used a validated and comprehensive measure of social functioning (the Social Functioning Scale), a comprehensive neurocognitive test battery, in addition to measures of psychotic symptoms, duration of untreated psychosis (DUP) and premorbid adjustment (the Premorbid Adjustment Scale). Lower childhood level of social adjustment and lower psychomotor speed had the strongest influence across measures of social functioning while symptoms and DUP had a weaker influence. The main result of the current study is that premorbid social adjustment and psychomotor speed had the strongest association with measures of social functioning in patients with FEP.

High levels of anomalous self-experience are associated with longer duration of untreated psychosis.
