- The individual thinks that harm is occurring, or is going to occur.
- The individual thinks that the perceived persecutor has the intention to cause harm.
According to the DSM-IV-TR, persecutory delusions are the most common form of delusions in paranoid schizophrenia, where the person believes "he or she is being tormented, followed, tricked, spied on, or ridiculed", or that their food is being poisoned. They are also often seen in schizoaffective disorder and, as recognized by DSM-IV-TR, constitute the cardinal feature of the persecutory subtype of delusional disorder, by far the most common. Delusions of persecution may also appear in manic and mixed episodes of bipolar disease, polysubstance abuse, and severe depressive episodes with psychotic features, particularly when associated with bipolar illness.
Medications for schizophrenia are often used, especially when positive symptoms are present. Both first-generation antipsychotics and second-generation antipsychotics may be useful. Cognitive behavioral therapy has also been used.

Collapsing across two studies that examined 40 British and 18 Australian false reporters (as determined by evidence overwhelmingly against their claims), these individuals fell into the following categories: delusional (64%), factitious/attention seeking (15%), hypersensitivity due to previous stalking (12%), were the stalker themselves (7%), and malingering individuals (2%) (Purcell, Pathe, & Mullen, 2002; Sheridan & Blaauw, 2004).
