N2 - Background: Childhood adversity is a well-established risk factor for the development of schizophrenia. In particular, there is evidence that childhood adversity increases the occurrence of positive symptoms, possibly through glucocorticoid influences on dopaminergic neurotransmission.Aims: To compare levels of childhood trauma in schizophrenia patients vs. healthy control persons, and to study the association between childhood adversity and the symptomatology of adulthood schizophrenia, as well as subjective and biological markers of psychological stress. Methods: Thirty-seven patients fulfilling ICD-10 criteria for schizophrenia and 39 healthy control persons filled out the comprehensive Childhood Abuse and Trauma Scale (CATS). Data were analyzed after a data-driven dichotomization into two groups of either high or low CATS score in patients and controls, respectively. The psychopathology of the patients was measured by the Positive and Negative Syndrome Scale (PANSS) and analyzed by a five-factor PANSS model. Measures of perceived stress (Perceived Stress Scale) and hypothalamic-pituitary-adrenal (HPA)-axis activity (9 AM plasma cortisol and daytime salivary cortisol output) were recorded.Results: As expected, patients had significantly higher total CATS scores than the control persons (>3-fold, P < 0.001), reflecting significantly higher scores across all subscales of the CATS. In patients, the total PANSS score did not significantly differ between the high and the low CATS score group (P = 0.2). However, there was a statistically significant higher level of positive symptoms in the high CATS group (P = 0.014), and no difference in other psychopathological domains. Correspondingly, when using the CATS score as a continuous variable, a strong association with positive PANSS scores was found (P = 0.009). The high CATS score group showed higher levels of perceived stress (P = 0.02), but there was no difference between the high vs. low CATS group in HPA-axis activity.Conclusion: Although causal inferences cannot be made from this cross-sectional study, the study adds support to the suggestion that childhood adversity specifically increases the occurrence of positive symptoms in adulthood schizophrenia in a manner that appears to leave HPA-axis activity unaltered.
