Post-traumatic stress disorder (PTSD) often makes headlines across America. Veterans fighting in Iraq and Afghanistan return to the life they left behind but are internally tormented by flashbacks, nightmares, anxiety, anger and depression. Many people suffer from PTSD after experiencing traumatic events in their lives. The Minnesota Multiphasic Personality Inventory (MMPI-2) is chosen as the basis for this assignment to evaluate someone exhibiting symptoms of PTSD. Sometimes PTSD symptoms are exaggerated or faked. The basic features and purpose of this tool will be discussed, as well as how it is used. An analysis of the MMPI-2 will reveal the relationship between the MMPI-2 and a major theory of personality. After identifying psychometric properties for PTSD populations, the question of the appropriateness of the MMPI-2 will be addressed by reviewing the literature. The latest ethical considerations will be analysed. Tool Selection, Features, Uses, and Purposes PTSD is a type of anxiety disorder resulting from experiencing a traumatic event in life. The person will relive or relive the event through flashbacks, nightmares, and fear-evoking memories. Some report being hyperaware or constantly aroused, expecting the event to repeat itself. Soldiers comment on falling to the ground with a loud bang, constantly scanning the area around them, having an exaggerated startle response. Many don't talk about their experiences; they have sleep problems, anger problems and difficulty concentrating. Alcohol and drug abuse are common to try to deal with internal anguish (PTSD Support Services, 2010). The MMPI-2 consists of 567 true and false questions that take 60 to 90 minutes to complete.
