What are the DSM-IV criteria and subtypes for Factitious Disorder?
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)
