Malingering is when a person exaggerates or makes up a physical or psychological illness or injury to seek personal gain (eg, paid sick leave, worker's compensation, avoiding military duty, obtaining financial compensation). It is a voluntary behavior directed toward accomplishment of a certain goal. It is not thought to be a form of mental illness, but it can exist in the context of another mental illness.


Malingering is not considered a mental disorder, since it occurs when a person intentionally fakes symptoms for personal gains. It is caused by whatever external factors that motivate the malingering. It is often associated with antisocial personality disorder]]> .


Risk Factors

A risk factor is something that increases your chance of getting a disease or condition.

Malingering often occurs in the work environment. It also occurs when there are legal disputes that involve money and medical issues.


Signs of malingering include:

  • Reluctance to undergo recommended tests
  • Failure to comply with prescribed treatments
  • Inconsistency between reported symptoms and physical findings on a medical exam


There is no way to definitively diagnose malingering. The diagnosis focuses on ruling out true physical or mental causes of symptoms. Psychological assessments can also help rule out other disorders, such as Munchausen's syndrome]]> . Depending on reported symptoms, other tests may include:

  • Physical exam
  • ]]>Magnetic resonance scan (MRI)]]> —a test that uses magnetic waves to make pictures of structures inside the body; used to find any type of abnormality (eg, tumors, lesions) in the brain

Since it is not a true illness, there is no real treatment for malingering. But when malingering is suspected, the doctor may:

  • Discuss the findings—If a doctor's findings do not match the symptoms and if malingering is suspected, the doctor may confront the patient.
  • Psychiatric consultation—If a psychiatric disorder is suspected, the patient may be referred to a mental health professional.


Malingering is not a mental disorder, so it can be prevented by making the decision not to exaggerate or make up symptoms for personal gain.
