Definition:
The Diagnostic and Statistical Manual of Mental Health Disorders, Fifth Edition (DSM-V) describes malingering as the intentional production of false or grossly exaggerated physical or psychological problems. Motivation for malingering is usually external. Some reasons that would cause a person to behave this way are: financial compensation; avoiding school, work or military service; obtaining drugs; or as a mitigating factor for sentencing in criminal cases.
Malingering is not considered a mental illness, and has been removed from the index in the DSM-V, but instead caries a Z Code as one of the other conditions that may be a focus of clinical attention.
