This paper describes the development of a 12-item questionnaire scale to measure hallucinatory predisposition. The scale, which conforms to at least one mathematical model of unidimensionality, includes both pathological items and other items which appear to represent sub-clinical forms of hallucinatory experience. The scale was used to test certain hypotheses concerning the link between aggressive-paranoid tendencies and hallucinatory predisposition (using the Eysenck's P scale) in a prison sample. The significant results presented do confirm such a link, although the precise behavioural correlates of hallucinatory predisposition require further definition.
