Sub-Types Of Childhood Trauma :
In this article, I briefly describe some of the main research findings in regard to the association between childhood trauma and risk of suffering from psychosis as an adult.
More specifically, I will examine which specific sub-types of childhood trauma may particularly increase an individual’s risk of developing psychosis as an adult, and if specific sub-types of childhood trauma are linked to increased risk of developing specific types of psychotic disorder as an adult and, if so, which specific types of psychotic disorder.
Study That Suggests Link Between Childhood Trauma And The Later Development Of Psychotic Depression :
A study carried out by Read et al. found that those individuals who had suffered from childhood trauma were more likely to have suffered from psychotic depression as adults. (Psychotic depression is similar to ‘ordinary’ major depression only there are additional symptoms of a psychotic nature – delusions, hallucinations and psychomotor agitation or psychomotor retardation).
More specifically, those who had experienced physical abuse or sexual abuse were found to have been particularly likely to have developed a psychotic depression later in life. (Of those in the study who had suffered from psychotic depression as adults, 59% had suffered physical abuse as children and 63% had suffered sexual abuse.)
Studies That Suggests Link Between Childhood Trauma And The Later Development Of Schizophrenia :
A study (Compton et al) found that of those who had been sexually abused as children and of those who had been physically abused as children, 50% and 61% respectively developed schizophrenia-spectrum disorders later in life.
Another study (Rubins et al) found evidence suggesting that whilst sexual abuse in childhood is associated with the later development of depression and schizophrenia, physical abuse during childhood is associated with the later development of schizophrenia’ alone.
Finally, a study by Spence et al found that both physical and sexual abuse were associated with the later development of schizophrenia and, of these two associations, the association between physical abuse and the later development of schizophrenia was the strongest.
Type Of Psychotic Symptoms :
Studies (e.g. Read, 2008) that have focused on the specific psychotic symptoms suffered by those who develop a psychotic illness AND have a history of childhood trauma have found that the most common are AUDITORY HALLUCINATIONS and PARANOIA.
