Factitious disorder involves the intentional production of physical

symptoms, while malingering involves the intentional production of symptoms for

internal psychological satisfaction.

Factitious disorder is diagnosed when the individual is consciously

aware of their symptom production, while malingering is diagnosed when the

individual is unaware of their symptom production.

In factitious disorder, symptoms are similar to amnesia,

while in malingering, symptoms are similar to personality disorders.

Factitious disorder is characterized by the intentional

production of symptoms to assume the sick role without external incentives,

while malingering is characterized by the intentional production of symptoms

for external incentives.
