Factitious disorder is defined in the Diagnostic and Statistical Manual of Mental Disorders as “physical or psychological symptoms that are intentionally produced or feigned in order to assume the sick role” (American Psychiatric Association, 2000, p. 513). It is differentiated from somatoform disorders on the basis of involuntary production of symptoms in the latter. However, in clinical practice the two types of disorders can be difficult to distinguish, since many patients present with a mixture of voluntary and involuntary symptoms (Feldman, Hamilton, & Deemer, 2001).
