Approach to the Patient
Review past records and history, if available Identify your role and establish rapport Identify any accompanying persons Attempt to identify reasons for presentation (referral, emergency) Chief complaint and history of present illness
Rigorously clarify vague details and chronology while preserving rapport Physical and Mental Status Examination Obtain collateral information, if possible
Consents for Release of Information if the patient is willing Emergency settings may not require a release
Confer with colleagues Present plan, targeting their chief complaint, to the patient, with rationale

Differential Diagnosis
Will depend on the chief complaint
Factitious Disorders and Malingering may focus on either physiological or psychological symptoms
Differential diagnosis can encompass any body system
![Page 5: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/5.jpg)
Significance of the Diagnoses
Patients fitting the criteria for the Factitious Disorders can undergo lengthy and expensive workups, with hours of time required for appointments, reviewing results, and performing procedures
Patients meeting criteria for Malingering can receive monetary benefits, freedom from responsibilities or legal charges, or otherwise utilize resources which may be appropriate for other patients
These patterns can continue, un-interrupted, without proper recognition and management

Factitious Disorder
DSM-IV-TR Criteria: A. Intentional production or feigning of physical or psychological
signs or symptoms. B. The motivation for the behavior is to assume the sick role. C. External incentives for the behavior are absent.
Subtypes: With Predominantly/Combined Psychological/Physical Signs and Symptoms
![Page 7: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/7.jpg)
Factitious Disorder Not Otherwise Specified
Disorders with symptoms that do not meet the criteria for Factitious Disorder. Factitious Disorder by proxy.

Factitious Disorders and Malingering Quiz 1
![Page 9: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/9.jpg)
Clinical Features
Physician-patient role disrupted as the physician must “catch” the patient in a falsehood
Patients may tamper with or contaminate laboratory samples, wounds or instruments
May fabricate physical and/or psychological symptoms within the same encounter
![Page 10: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/10.jpg)
The Sick Role
Described by a medical sociologist, Parsons in 1951
Being sick confers certain rights and responsibilities on the patient Rights: The patient is not held
responsible for being ill, and the patient is exempt from “normal role obligations”
Responsibilities: The patient must “seek technically competent help” and must “want to get well”
Patients who assume the sick role may benefit from relief of duty toward undesirable responsibilities and obligations, and from sympathy generated in the absence of blame regarding their condition
![Page 11: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/11.jpg)
Regarding Primary and Secondary Gain
These concepts were originally described by Freud and again by Barsky Definitions in the following slides
Appeared, with definitions, as recently as DSM-III-R There, both concepts were defined in the setting of Conversion Disorder
Both sources define primary and secondary gain as UNCONSCIOUS processes, i.e. the individual is unaware of the motivation
It may be more helpful to think of Factitious Disorders and Malingering as defined in DSM-IV-TR criteria Factitious Disorder patients seek to assume the sick role, but have NO
“external incentives” for doing so Patients who malinger are seeking external incentives
Economic gain, avoiding legal responsibility or improving physical well being
![Page 12: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/12.jpg)
Primary Gain
“Reduction in intrapsychic conflict and the partial gratification accomplished by the defensive operation” Defense may be primitive or mature
Produces “a symptom of the illness” I.e. conversion, factitious or somatoform symptom
Defined most recently in DSM-III-R There related specifically to Conversion Disorder
![Page 13: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/13.jpg)
Secondary Gain
“Acceptable or legitimate interpersonal advantages that result when one has the symptoms of a disease”
May be tangible or intangible rewards: Money, desired working conditions Sympathy and concern from friends or family
Popularly used to describe specific financial benefits from intentional symptom production This is inconsistent with the original definition
![Page 14: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/14.jpg)
Tertiary Gain
Gain realized by a separate party due to the patient’s illness
Similar to secondary gain, tertiary may be tangible or intangible
As with primary and secondary gain, tertiary gain should be considered to be an unconscious goal
![Page 15: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/15.jpg)
Epidemiology
Female predominance Young age
Psychologically “immature”
Many have health care experience, professionally or through interactions with others, and some medical knowledge- self taught or formal
Generally, complaints are confined to a single hospital system
Patients are more likely to be living within the surrounding community
![Page 16: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/16.jpg)
Münchausen’s Syndrome
10% of Factitious Disorders Male predominance Multiple, frequent presentations to
hospitals with provocative or fantastic complaints (pseudologia fantasica) Can be life-threatening symptoms Often seek invasive testing or
involved treatments Peregrination: Serially visiting
hospitals over a wide area Name taken from fantastic
account of the exploits of Baron Karl Friedrich Hieronymous von Münchausen, a real life German cavalry officer in the Russian army during the 1700s
![Page 17: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/17.jpg)
Factitious Disorder and Malingering Quiz 2
![Page 18: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/18.jpg)
Treatment
Establish rapport with a single provider Prior knowledge of past complaints allows current complaints to
be examined in perspective
Continuity of care across providers also minimizes unnecessary diagnostic and treatment costs
Psychotherapy to address underlying conflicts and stressors Nearly always outpatient level of care
![Page 19: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/19.jpg)
Course and Prognosis
Outcomes largely dependent on patient engagement in treatment and rapport with providers
Range from no improvement with continued dysfunction to remission of symptoms without expected recurrence
![Page 20: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/20.jpg)
Malingering
No firm criteria given in DSM-IV-TR Strongly suspect if any combination of the following:
Medicolegal context of presentation. Marked discrepancy between the person’s claimed stress or
disability and the objective findings. Lack of cooperation during diagnostic evaluation and in
complying with the prescribed treatment regimen. The presence of Antisocial Personality Disorder.
![Page 21: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/21.jpg)
Malingering
DSM-IV-TR provides a concept of this diagnosis, stating: “The essential feature of Malingering is the intentional production of false or grossly exaggerated physical or psychological symptoms, motivated by external incentives…”
![Page 22: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/22.jpg)
Factitious Disorder and Malingering Quiz 3
![Page 23: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/23.jpg)
Clinical Features
Malingering is a diagnosis based on a specific symptom at a specific time
A person may malinger some or all of their symptoms Mental health providers (psychiatrists and psychologists)
were not superior to lay persons in detecting malingering
![Page 24: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/24.jpg)
Epidemiology
One review of 33,000 cases seen by neuropsychologists (usually Ph.D. or Psy.D. level providers who do neuropsychometric testing) reported rates between 8% of medical and psychiatric “cases” and up to 30% of disability or worker’s comp evaluations
![Page 25: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/25.jpg)
Management
Obtain collateral information from parties who know the patient, if possible
Neuropsychological testing can aid in clarifying symptoms and contains an internal metric for poor effort
In an emergency situation, prioritize patient safety above suspicion of validity of symptoms
![Page 26: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/26.jpg)
Course and Prognosis
Patients are intentionally manufacturing symptoms with an intentional goal, and can be difficult to engage or collaborate with
This diagnosis is not due to a mental disorder, therefore there is no treatment, per se
Patients who have malingered in the past may do so again if they feel the risks and benefits are favorable to them
![Page 27: Factitious Disorders and Malingering Kevin Reeves, MD Assistant Professor-Clinical, Psychiatry Wexner Medical Center The Ohio State University College.](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649f355503460f94c53be9/html5/thumbnails/27.jpg)
