Abstract

Research has suggested that many with schizophrenia have been exposed to significant trauma, both after and before the onset of their illness. Less clear is how commonly significant levels of trauma symptoms are found in schizophrenia, how often they co-occur, and what their relationship is with positive and negative symptoms. To examine these issues, we concurrently assessed trauma history, trauma symptoms using the Trauma Symptom Inventory, and symptoms using the Positive and Negative Syndrome Scale. Participants were 68 individuals with schizophrenia spectrum disorders who provided reliable reports of at least one traumatic event from an original sample of 81 individuals. Results revealed that two thirds of participants reported clinically significant trauma symptoms that included at least intrusive experiences, defensive avoidance, or dissociation. Greater levels of depression and disturbance of volition were significantly correlated with greater levels of anxious arousal, intrusive experiences, defensive avoidance, dissociation, and total number of significantly elevated trauma scales. Delusions were correlated with intrusive experiences, dissociation, and number of significantly elevated trauma scales, whereas hallucinations were correlated with irritability and total number of significantly elevated trauma scales. Results suggest that trauma symptoms may be commonly experienced in schizophrenia and linked with the phenomenology of the disorder.

  • In cognitive models of psychosis, appraisals of anomalous experiences as personally relevant, threatening and/or attributed to an external cause are proposed to contribute to the development of psychotic symptoms.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
