People with Schizotypal Personality Disorder have a reduced capacity for closeness with others which is present from an early age. They often have distorted or eccentric thinking, perceptions, and behaviours that can make them appear odd.

For a diagnosis of Schizotypal personality disorder to be made, people will display at least five of the following:

• Ideas of reference

• Magical thinking or odd beliefs which are inconsistent with cultural norms

• Unusual perceptions including bodily illusions

• Odd speech and thinking

• Suspiciousness or paranoia

• Affect that is inappropriate or constricted

• Few close friends or confidants, other than relatives

• Social anxiety which does not improve with familiarity; paranoid fears rather than negative self-judgements
