norms by authors (n=928 twin pairs)



UK-based norms for your gender group of healthy individuals are taken from author's paper (Mason 2005).

It is not suggested that these are in any sense clinical cut-offs, and clinical norms have not been established. However, they do help to define, for the purposes of experimentation, those people scoring above a given psychometric point in the distribution.

There is much evidence that psychosis prone/schizotypy is a construct with separable and well-identified components and what it means to combine these is largely unknown and the effects difficult to interpret. Authors suggest to retain the multidimensional approach to measurement and research in the area; in the case of the O-LIFE by considering its four scales separately:

• Unusual Experiences – items describing perceptual aberrations, magical thinking, and hallucinations. It is phenomenologically related to the positive symptoms of psychosis, and measures a trait often termed positive schizotypy.

• Cognitive Disorganisation – items that tap aspects of poor attention and concentration, as well as poor decision-making and social anxiety. It can be seen to reflect thought disorder and other disorganised aspects of psychosis.

• Introvertive Anhedonia – items that describe a lack of enjoyment from social and physical sources of pleasure, as well as avoidance of intimacy. It can be seen to reflect weakened forms of negative symptoms, so-called negative schizotypy, or alternatively the schizoid temperament.

• Impulsive Nonconformity – items describing impulsive, anti-social, and eccentric forms of behaviour, often suggesting a lack of self-control.
