Table 5 Outline of Incongruence dimension scale. Table shows key points and ranges on the I dimension together with the criteria defining the ranges. The S set of psychotic symptoms are those recognized as having special weight in the diagnosis of schizophrenia and schizoaffective disorder (thought echo, insertion, withdrawal or broadcasting; passivity experiences; hallucinatory voices giving running commentary, discussing subject in third person or originating in some part of the body; bizarre delusions; catatonia). More details including explicit guidelines for ratings can be found on page 6 of the BADDS rating guidelines (Appendix A).
