Diagnostic legitimacy of factitious disorder with psychological symptoms

The authors question the clinical status of factitious disorder with psychological symptoms as a mental disorder. In particular, they argue that unresolved issues regarding the motivational basis of this disorder and the lack of clearly delineated inclusion, exclusion, and outcome criteria seriously compromise its diagnostic legitimacy. Two case reports are presented to illustrate these difficulties. Future studies should consider these empirical and conceptual difficulties in refining the diagnosis of factitious disorder with psychological symptoms for DSM-IV.
