ABSTRACT
In personality psychology the concept of dimensionality is somewhat different, if only because it refers to continua that describe smoothly varying individual differences in healthy functioning that have no necessary reference point in abnormality. Most of the research on the dimensionality of schizophrenia is done under the umbrella of this broadened schizotypy concept. Consequently, 'schizotypy', as the less deviant bedfellow of 'schizophrenia', has come into common usage among professionals as a way of expressing, for those who believe in it, the apparent dimensionality of psychosis. A radical feature of the fully dimensional construction of psychosis—distinguishing it from the quasi-dimensional alternative—concerns its approach to the study of 'aetiology'. In personality psychology the concept of dimensionality is somewhat different, if only because it refers to continua that describe smoothly varying individual differences in healthy functioning that have no necessary reference point in abnormality.
