The document summarizes research on the relationship between childhood trauma and psychosis. It finds that childhood abuse and neglect are strongly associated with psychotic symptoms later in life, with a clear dose-response relationship. Experiencing multiple types of trauma as a child increases the likelihood of developing psychosis as an adult by a factor of 18 to 193. Theories on how childhood trauma may lead to psychosis include cognitive, psychodynamic, dissociation, and attachment-related mechanisms.

Editor's Notes
- Our most recent study confirms previous studies (such as the work of Colin Ross in Houston, Texas) showing that child abuse is significantly related to the positive symptoms of schizophrenia, particularly hallucinations. Note that the relatively rare tactile hallucinations were found ONLY in patients who had been abused as children. We did not , however, confirm previous findings that paranoid delusions, ideas of reference or thought insertion were significantly more common in those subjected to child abuse, although all these findings were in the expected direction (but did not attain statistical significance). We again found many examples of the specific content of symptoms being abuse related, the most poignant being where the voices heard are the c=voices of the perpetrator telling patients to kill themselves. WE also found that for 14% of the abused but only 3% of the non-abused patients their hallucinations or delusions involved the theme of a struggle between good and evil, often between God and Satan. ( a statistically significant difference) There were no differences in terms of negative symptoms. Please note the difference in terms of having two or more DSM ’Characteristic Symptoms’ The number required for a diagnosis of schizophrenia.
