these to 504 items that were determined to be independent of one another. They then gave these items to psychiatric inpatients at the University of Minnesota Hospital. These inpatients were further divided by diagnosis, and the responses of each group were compared with non-patients who had come to the hospital as visitors or relatives. The idea was to develop a scoring scheme that would differentiate those with mental disorders from those without. In this sense, the content of the item was less important than its ability to discriminate between those individuals with a specific disorder and those without, as well as between disorders.

      Minnesota Multiphasic Personality Inventory (MMPI): an assessment measurement of personality traits, used in psychopathology to identify response patterns suggesting a psychological disorder based on empirical comparison to the general population

      In 1989, a new version of the MMPI, the MMPI-2, was released, which improved the generalizability of the test. The new test was “normed” on a better representation of the general population in terms of race, age, occupational level, income, and geographic location. The new version contains 567 items and uses a true, false, or can’t say format. One real advantage of the MMPI and MMPI-2 is that they were developed in a more empirical manner by comparing how the pattern of responding matched populations with specific disorders versus healthy individuals rather than the content of the items. It is also possible, by using a normal statistical curve, to determine how extreme an individual’s responses are. Thus, the scales are presented in a dimensional manner, and it’s easy to determine if a person endorses more or less of a category of experiences than the general population.

      The clinical scale in the MMPI uses the following categories:

       Hypochondriasis—Individuals who endorse these items show an excessive concern with bodily symptoms.

       Depression—Individuals who endorse these items display characteristics of depression such as trouble sleeping, loss of appetite, feeling sad, suicidal thoughts, and loss of interest in positive events.

       Hysteria—Individuals who endorse these items tend to view and experience the world in an emotional manner. They may overdramatize their situation. They may also experience emotional difficulties through bodily symptoms such as headaches or upset stomach when in a difficult psychological situation.

       Psychopathic deviate—Individuals who endorse these items display antisocial tendencies and experience conflicts with their environment. They may also exploit others without remorse.

       Masculinity–femininity—These items reflect the degree to which an individual endorses the traditional gender role of males or females.

       Paranoia—Individuals who endorse these items display suspiciousness of others. They also view the world in terms of “who is out to get them.”

       Psychasthenia—Individuals who endorse these items display excessive anxiety and obsessive behavior.

       Schizophrenia—Individuals who endorse these items display bizarre disorganized thoughts along with a lack of normal contact with reality including social aloofness. Various sensory problems such as hallucinations may be present.

       Hypomania—Individuals who endorse these items experience high-energy states associated with poor judgment and impulse control.

       Social introversion—These items reflect the extent to which an individual’s answers indicate social introversion and extraversion.

      By placing the responses of an individual to questions in each of the categories on a normal distribution, it is possible to see which categories deviate from responses seen in the general population (see Figure 4.1). In addition to the clinical scales, the MMPI also contains validity scales. These scales were designed to determine whether the person is trying to skew the results by either “faking good” or “faking bad.” One type of item included in these scales would be one that most healthy individuals would not agree to such as, “I have never told a lie.” This last item would be found on the lie or L scale. The infrequency or F scale is composed of items that are infrequently endorsed by the general population. Endorsing these items could come about because the person wanted to look as if he or she had psychological problems (“faking bad”). It could also be the case that the individual was confused or could not read or understand the items. The defensiveness, or K, scale seeks to identify individuals who deny having any psychological problems (“faking good”). The number of times the person responds with “can’t say” can be noted to help determine the validity of the MMPI. Further, as might be expected after more than 70 years of use, a variety of additional scales have been developed, which have been used for both clinical and research purposes.

      Projective Tests

      Projective instruments are assessment tests composed of ambiguous stimuli. They can range from seemingly random patterns such as an inkblot to ambiguous drawings of individuals or objects. The individual is asked to describe what the patterns look like, what they remind him or her of, or what is being depicted in the drawing.

      projective instruments: assessment tests that use ambiguous stimuli to elicit the internal cognitive and emotional organization of a person’s primary thought processes

      The basic idea of projective testing is based on the theoretical ideas of Sigmund Freud and others who sought to understand the dynamics of the mind. One important distinction Freud made was between types of thinking (Erdelyi, 1985; Westen, Gabbard, & Ortigo, 2008). Primary process thought, which is seen in dreams or letting your mind wander, is not organized logically but in terms of associations between thoughts and feelings. Secondary process thought, on the other hand, is logically organized. Freud suggested that it was possible to understand the cognitive and emotional connections of a person’s mind in terms of primary process. Freud’s technique for exploring these connections was free association and dream analysis.

      The basic technique of free association was to have a person lie on a couch and say whatever came into his or her mind. Since the therapist sat behind the client, there was little in the environment for the client to react to. It was the therapist’s job to notice how a person’s thoughts and emotions were connected. During free association over a period of months, it was assumed that patterns of responding would emerge. It could be, for example, that whenever a client talked about his pet, he would feel sad, or whenever someone began to describe a certain event, he would change the topic.

      Projective techniques were formally introduced in the first half of the 1900s as a means of detecting primary process types of thinking and feeling including instinctual and motivational processes. Since there were few techniques for understanding the connections
