Abstract: 534 college students were selected by their scores on several scales of psychosis proneness, were interviewed, and were given the Eysenck and Eysenck (1975) Psychoticism Scale (P-Scale). After 10 yr, 508 subjects were reinterviewed. Subjects identified by initial deviantly high scores on the P-Scale (N = 26) did not differ from control subjects (N = 310) on the rate of subjects who developed psychotic disorders or in reports of psychotic relatives. However, High P subjects exceeded controls on ratings of psychoticlike experiences and on symptoms of schizotypal and paranoid personality disorder. The findings indicate that high scorers on the P-Scale are psychoticlike but are not at heightened risk for psychosis.
