There are many measures that have built-in malingering items, aka items that almost no one actually endorses so it hints that people are lying or exaggerating
I found a great literature review which explains the whole process of malingering detection.
According to Resnik (1997), malingering detection must start with a thorough clinical interview and precise behavioral observations.
He proposed several indicators of feigning psychiatric illnesses, particularly psychotic symptoms, in patients.
He noted that patients rarely have the stamina to persistently perform in a way that is consistent with the symptoms they are attempting to feign.
Patients may also behave differently when speaking to differing members of a multidisciplinary treatment team. That's why he sugested that the clinician must conduct long interviews focused on specific details that require the patient to maintain a consistent report.
Clinical interview is a great source of infomation but many authors agree that just clinical interview is not enough. As Reid (2000) proposes that a clinical interview and behavioral observations must be paired with data from objective psychometric measures in order to formulate a convincing case.
The following literature review states some of the mose successful psychometric measures but also explains the strengths and weaknesses of each of them.
