The paper discusses the financial motivations for people, especially veterans, to overreport post tramatic stress disorder (PTSD) symptoms. The paper then examines whether the Minnesota Multiphasic Personality Inventory, Second Version (MMPI-2) is able to screen out those faking or exaggerating their symptoms. The paper explores the research that demonstrates how the MMPI-2 alone is not an appropriate tool for the diagnosis of PTSD, especially in populations with incentives to try to falsify positive results. The paper comes to the conclusion that the clinician may have a responsibility to probe and even investigate an individual's familiarity with the test and its qualifications before making a PTSD diagnosis using the MMPI-2 as the diagnostic tool.

Characteristics, Uses, and Purposes of the MMPI-2
Identification of Psychometric Properties

From the Paper:

"The MMPI-2 is the most widely used assessment tool in clinical psychology. This is largely due to the reliability and validity of its assessments. There are four different validity scales in the MMPI-2: the Cannot Say Scale, the Infrequency Scale, the Lie Scale, and the Defensiveness Scale (Trull, 2005). Each of these scales picks up on different factors that can impact the validity of any test results. For example, the Cannot Say Scale measures the number of unanswered items. The Infrequency Scale measures deviant responses, which can indicate a tendency towards symptom exaggeration. The Lie Scale is a set of questions geared towards detecting when someone is trying to make himself seem better adjusted than he actually is. This is different from the Defensiveness Scale, which relates to people's willingness to admit problems to themselves versus an intentional lie to make themselves seem better adjusted. (Trull, 2005)."
