Hello Olga,

(This approach to negative psychopathology in schizophrenia with its concept of basic symptom and basic stages seems to be  considered  oversimplification by some (20 years later).)

The  following mentions :

BSABS = Bonn scale for the assessment of basic symptoms ( available in several languages)

FBF= Frankfurter Beschwerde Fragebogen

Have you considered developing your own?

Dear Jutta,

let me thank you for your helpful advice, which gives me direction of further research. Although I am acquainted with BSABS, I have not heard about Self Report method introduced by Italian researchers, mentioned in your answer. So I will ask authors to have a look at their questionnaire. If I found cenesthetic scale I will try to translate it, if not - I will develop my own. I am trying to aplicate my body -self model to schizophrenia, using both: self-report and experimental method. Are you interested at a body image/body self concept in your research work?

Regards,

Olga

In my research I recall coming across the EAWE: Examination of Anomalous World Experience, which is a semi-structured interview aimed at identifying anomalous experiences. I remember stumbling upon an assortment of papers related to your question when I was reading about abnormalities in the sense of agency, but I can't recall specific self-report questionnaires. One study that comes to mind proposed a theory of deficits in the mirror neuron system from studies which found abnormal responses by schizophrenics during the "rubber hand" illusion test. When I get a chance, I'll sift through my repository and see what I can come up with. This sounds like the perfect question for V.S. Ramachandran.  =)

I managed to find a few references that may be of use. Actually, one of them is a master's thesis which contains a self-report questionnaire which may be like what you are looking for. Otherwise, the rest of the articles don't explicitly provide a questionnaire, but there are a few scripts for semi-structured interviews and if you dig around the references you can probably find what you're looking for.
