for a detailed account of phenomena that have in common a somehow deformed sense of fi rst-person perspective – in brief, a disorder or defi ciency in the sense of being a subject, a self-coinciding center of action, thought, and experience 1 . The scale is mainly designed for conditions in the schizophrenia spectrum, but it cannot be used alone as a diagnostic instrument (self-disorders are not listed by the DSM-IV or ICD-10 as diagnostically crucial or even important features of schizophrenia; derealization and depersonalization are mentioned as nonessential features of schizotypy).
