Psychotic symptoms in the general population
Surveys of unselected general population samples have shown that a large number of individuals report any experience resembling the clinical psychosis concept. The Internet can be an effective medium for collection of such epidemiological large-scale psychology- and psychiatry-related data.
The main questions are:
- What is the co-morbidity between sub-clinical positive psychotic symptoms and depression, the relationship to season of birth and complications around childbirth?
- Is it possible to ask for positive psychotic symptoms in a web-based questionnaire in the general population?
