Signs of malingering are evident when there is a marked difference between the reported signs and actual observed signs. For example those individuals who report loss of appetite or loss of interest in socializing or a depressed nature can be closely tracked when they are eating, having desserts, interacting with other members, and sleeping peacefully. Their eating habits and sleeping pattern can give a clear idea about malingering. Such a type of behavior can also be observed in presence of external incentive such as for obtaining prescription drugs. Yet another important marker for identifying malingering is reporting that they hear voices while asleep or hear them continuously rather than in intervals.
In addition to the above mentioned signs, individuals also do not participate appropriately during clinical examination, medico-legal context, or show signs of antisocial personality disorder. Patients with malingering often bitterly express their symptoms and also exhibit a feeling of distress while reporting of ailments .
There is no one single method to diagnose malingering. Clinicians use open ended questions during the evaluation process. It is necessary that the questions should be asked without giving any kind of clues and the interview should be carried out for a longer duration. In such situations, it would get difficult for the individual to maintain the fake presentation  .
Clinicians often recognize malingers by the extent of exaggeration of symptoms. For example, individuals who present with complain of schizophrenia often claim global confusion. This is so because, malingers are often under the impression that global confusion is the trademark of all mental disorders. Over exaggeration of symptoms gives a clear indication to the clinicians that the individual is pretending and is not a prey to any form of medical illness, but is malingering for some personal benefit .
No specific treatment regime exists for malingering. However, this is no way implies that the patient should be regarded as liar. Malingering may coexist with other psychosocial problems and therefore, methods should be employed for treating underlying disease conditions if any. In many cases, the cause of malingering could be genuine, such that when a female wants to escape the company of her husband due to his abusive nature .
Moreover, it has also be seen that, individuals often seek malingering when they actually have psychiatric disorders and are unable to express the same due to language barrier or other constraints. Therefore, it becomes necessary to arrange for an interpreter whenever possible, to design proper interventions.
The malingering behavior lingers on unless the motive behind such a kind of act is fulfilled. Or the benefit desired outweighs the distress and inconvenience involved for seeking medical confirmation for the fake illness .
Personal gain is the basic and the major motive behind the act of malingering. Individuals with a selfish motive tend to overstate physical as well as psychological signs and symptoms. Such a kind of act of overstating symptoms is majorly done to abstain from school, gain monetary benefit, obtaining drugs, to get appointed in military service or to get lighter criminal sentence. In some cases, malingering is done to gain sympathy or to attract attention .
Malingering is a common practice and is widely prevalent across the globe. It is more common in settings of military, factories, prison and criminal prosecutions. Individual at any age can practice malingering. Even a child aged 9 years can also seek help from malingering for personal gain. Studies have shown that, about 13% of emergency attendees pretended illness in order to gain food, money, shelter, medical treatment and avoidance of work, family responsibilities and imprisonment.
Another set of studies have also postulated the fact that, malingering is also prevalent amongst the psychiatric population, and about 10 – 12% of them have the habit of exaggerating their symptoms. It has been estimated that in the year 1995, the total cost of health insurance claimed by fraud is about $59 billion in the US.
The exact incidence of malingering is not known. It is certainly not a type of mental illness or a form of psychopathology. Such a kind of condition is purposively created for gaining benefit or for some external purpose. However, in many cases, malingering can often accompany other mental illnesses .
Malingering can be classified under 3 different categories namely: pure malingering, partial malingering and false imputation. Pure malingering is a condition, wherein the individual reports of having symptoms which are not at all present. Partial malingering involves exaggeration of symptoms which are present. False imputation is a condition, wherein, individuals falsely attribute the symptoms to an unrelated etiology .
Malingering is not a disease, neither a mental condition which can be prevented. Conscious efforts for not exaggerating the symptoms can help prevent such a type of condition.
Individuals often have the habit of fabricating symptoms purposively to have some sort of benefit. For example, students may pretend to suffer from conditions they are not suffering from, to avoid attending school or for gaining sympathy from others. Malingering is not same as factitious disorder or somatization disorder .
