The Rust Inventory of Schizotypal Cognitions (RISC) is a short objective inventory for assessing the cognitions associated with schizotypal personality disorder and acute schizophrenia. It differs importantly from all previously available scales in emphasising cognitive content rather than focusing solely on diagnosis and has been developed and standardised with special attention to the presence of these forms of thought in the general population rather than in psychiatric patients. The RISC is, therefore, able to provide an estimate of schizotypal personality disorder and client risk for associated symptoms that are terminologically related to acute schizophrenia.

The inventory contains 26 statements to which the client is asked to respond. Although containing no obviously extreme items, its cumulative effect may be used to identify bizarre and eccentric thought patterns. The RISC provides a significant instrument for clinical assessment, occupational counselling, and for academic research in psychiatry and clinical psychology. It's also quite fun too

The RISC is available from The Psychometrics Centre. Contact us for details.
