A 29 item Psychoticism scale was administered to 77 psychotic patients. Scores were largely unaffected by age, vocabulary and sex; P scale scores were independent of N, although not of E and L, and were stable over time. P scale scores did not discriminate between the psychotics and 35 neurotics and 112 normals. However, within the psychotic group, those patients who had delusions of `disintegration', thought disorder and affective flattening had significantly higher scores than those psychotics without these signs.
