Schizotypy Personality Scale (STA)

The Schizotypy Personality Scale (STA) is a test for schizotypal personality disorder. It measures the presence of schizotypal traits, such as psychotic episodes, irrational beliefs, cognitive disorganization, anxiety, reality distortion, blunted emotions, hostility and asocial behaviour, in non-institutionalized adults. The paranoid, schizoid, and schizotypal personality disorders in the DSM-IV lie at the less extreme end of the schizophrenic disorders. The STA is a subscale of the Schizotypal Questionnaire (STQ) developed by Claridge and Brooks (1984). It has 37 questions and can be completed in 5-10 minutes. Answer according to how you generally feel.
