Abstract

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.

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.

Dissociative Disorders

Dissociative Disorders

Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.
Dissociative Fugue
A hallmark feature of dissociative disorders is the dissociative fugue...
