Patients with Factitious disorder knowingly pretend to have the symptoms of an illness in order to assume the role of an ill person.

According to the DSM-IV, the three subtypes of Factitious disorder are:

  • Psychological - patient presents with symptoms that are almost entirely psychological
  • Physical - patient presents with symptoms that are almost entirely physical
  • Psychological and physical - patient presents with symptoms that are a mix of psychological and physical

According to the DSM-IV, there are three criteria that must be met in order for a diagnosis of factitious disorder to be made:

  • Patient's symptoms must be willfully faked
  • The patient is engaging in this behaviour in order to appear ill
  • There exists NO extrinsic reasons for the patient to do this (e.g., avoidance)
