SUMMARY
The aims of our studies were on the one hand to analyse the factor structure of Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE, Mason and Claridge, 1996) and Dissociative Experiences Scale (DES, Carlson and Putnam, 1993) and on the other hand to check the criterion validity of O-LIFE and the continuity between symptoms of schizophrenia and dimensions of schizotypy. Our further aim was to test how reports of general childhood trauma, childhood physical, emotional and sexual abuse are connected to present symptoms of schizophrenia, possibly via such mediating factors as posttraumatic stress symptoms and dissociation. It was also our aim to analyse if trauma history is possibly connected to the duration of illness, the number of hospitalisations, suicide attempts and other measures of suicidality.
In our first study 406 university students were included, in our second study altogether 102 inpatients and outpatients with the diagnosis of schizophrenia and schizoaffective disorder, as well as 29 healthy controls took part.
In our first study evidence supported the four-factor hypothesis of O-LIFE and the three-factor structure of DES. In our second study positive schizotypy was significantly correlated with the positive and negative schizotypy with the negative symptoms of schizophrenia. In the whole sample of patients positive symptoms of schizophrenia and delusions were predicted by general childhood traumas. In the group of men general traumas were the only significant predictors of positive symptoms, especially delusions. In the group of women childhood physical abuse was the only predictor of thought disorder. Several of our regression models did not reach significance, so our results are only showing tendencies. Neither posttraumatic stress symptoms, nor dissociation have been proved to be significant mediators between childhood traumas and psychotic symptoms. Childhood emotional abuse and the subjective effect of it were correlated with a greater intensity of suicidal ideation, partly independently of depression. Patients reporting more childhood abuse and judging more negatively their childhood emotional abuse exhibited their first symptoms at a significantly earlier age.
Based on our results, it can be concluded to be important for future research designs to include and further analyse the effects of gender differences. As a relevant therapeutic implication, it must be mentioned that early traumas might as well mean a higher suicide risk and a less favourable course of illness for patients with schizophrenia.
