Persecutory delusions are a common psychiatric symptom, affecting between 50 and 90% of those with psychosis.T hey are associatedw ith high levels of distress, social isolation and hospitalisation. Psychological theories of persecutory delusions have been developed in order to inform the care of this distressing symptom. Objectives. The current thesis has two aims.
