title: The Rust Inventory of Schizoid Cognitions (RISC): a psychometric measure of psychoticism in the normal population.
abstract: The Rust Inventory of Schizoid Cognitions (RISC) is a new, psychometrically constructed, cognitively based, short questionnaire of psychoticism. It differs from previous scales in having been developed and standardized with special attention to normal distribution in the general population, using cognitive theory to generate the relevant test specification. The scale has good reliability and validity, and can clearly discriminate acute schizophrenics from normals. Although containing no obviously extreme items, its cumulative effect may be used to assess the prevalence of bizarre and eccentric thought patterns in psychiatric patients, and as an estimate of psychotic risk in the general population.
