MMPI-2: The Most Widely Used and Researched Tool for Clinical and Forensic Psychology


MMPI-2: Assessing Personality and Psychopathology




The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is a widely used and researched clinical assessment tool that helps diagnose mental health disorders. It is also used in non-clinical settings to screen candidates for high-risk public safety positions, such as police officers, firefighters, pilots, and air-traffic controllers. Additionally, it is used in forensic settings to evaluate criminal defendants, civil litigants, and personal injury claimants.

The MMPI-2 consists of 567 true-false questions that take about 60 to 90 minutes to complete. The test measures various aspects of personality and psychopathology through a number of validity and clinical scales. The validity scales assess the accuracy and honesty of the test-taker, while the clinical scales assess the presence and severity of various psychological disorders.


The MMPI-2 is a powerful tool that can provide valuable information about a person's psychological state, but it also requires careful administration, interpretation, and communication. In this article, we will explore the history, types, administration, measurement, interpretation, and limitations of the MMPI-2.


History of MMPI-2




The MMPI-2 was developed as a revision of the original MMPI, which was published in 1943 by clinical psychologist Starke R. Hathaway and neuropsychiatrist J. Charnley McKinley at the University of Minnesota. The original MMPI was designed to be an objective tool for assessing different psychiatric conditions and their severity. The test items were selected based on their endorsement by people diagnosed with different mental health conditions.


The original MMPI became one of the most widely used and researched psychological tests in history. It was used in various settings, such as psychology clinics, hospitals, correctional facilities, and pre-employment screenings. However, over time, the test also faced some criticisms and challenges. Some of the issues that were raised included:


  • The inadequacy of the original norm group, which consisted of mostly white, rural, and lower-educated individuals from Minnesota.



  • The possible test bias due to the cultural, social, and linguistic changes that occurred since the 1930s.



  • The outdatedness and inappropriateness of some of the test items, which contained sexist, racist, or offensive language.



  • The lack of validity scales to detect lying, defensiveness, or faking on the test.



  • The overlap and redundancy of some of the clinical scales, which reduced their specificity and discriminability.



In response to these issues, the MMPI underwent a major revision in the late 1980s. The revised version, called the MMPI-2, was published by the University of Minnesota Press in 1989 and revised again in 2001. The MMPI-2 addressed some of the problems of the original MMPI by:


  • Using a new norm group that consisted of 1,138 males and 1,462 females between the ages of 18 and 80 from diverse regions and communities within the U.S.



  • Removing or rewording some of the outdated or inappropriate items.



  • Adding new items to cover more relevant topics and symptoms.



  • Incorporating new validity scales to assess lying, defensiveness, faking good, faking bad, and other response styles.



  • Reducing the overlap and redundancy of some of the clinical scales by creating new subscales.



The MMPI-2 also underwent some updates in 2003 and 2009. In 2003, a new set of clinical scales called the Restructured Clinical (RC) Scales were introduced to improve the specificity and discriminability of the original clinical scales. In 2009, a new validity scale called the Symptom Validity (FBS) Scale was added to detect symptom exaggeration or malingering.


Types of MMPI-2




There are different versions of the MMPI-2 that are used for different purposes and populations. The main types of MMPI-2 are:


  • The standard MMPI-2: This is the most commonly used version of the test. It consists of 567 items that measure 4 validity scales and 10 clinical scales. It also includes several supplementary scales and content scales that measure specific aspects of personality and psychopathology.



  • The MMPI-2 Restructured Form (MMPI-2-RF): This is a shorter version of the test that consists of 338 items that measure 9 validity scales and 9 clinical scales. It also includes several higher-order scales and specific problem scales that measure broad and narrow dimensions of personality and psychopathology. The MMPI-2-RF is designed to be more efficient and accurate than the standard MMPI-2.



  • The MMPI-2 Extended Score Report (MMPI-2-ESR): This is a computer-generated report that provides additional information about the test-taker's scores on the standard MMPI-2 or MMPI-2-RF. It includes graphs, tables, descriptions, interpretations, and recommendations based on the test results.



  • The MMPI-A: This is a version of the test that is designed for adolescents aged 14 to 18 years old. It consists of 478 items that measure 4 validity scales and 10 clinical scales. It also includes several supplementary scales and content scales that are relevant for adolescents.



How to Take MMPI-2




The MMPI-2 can be administered by computer, CD, or paper-and-pencil. The test-taker is instructed to answer each item with either true or false according to their own feelings, thoughts, or experiences. There is no time limit for completing the test, but it usually takes about 60 to 90 minutes for the standard MMPI-2 and about 35 to 50 minutes for the MMPI-2-RF.


should also monitor the test-taker's behavior and response style during the test. The test administrator should not influence or interfere with the test-taker's answers in any way.


Some tips for taking the MMPI-2 are:


  • Answer honestly and spontaneously. Do not try to lie, fake, or impress anyone with your answers.



  • Answer based on your current situation and feelings. Do not answer based on how you used to be or how you wish to be.



  • Answer all the items. Do not skip or leave any items blank.



  • Do not overthink or analyze the items. Do not look for hidden meanings or try to figure out what the test is measuring.



  • Do not let your mood or emotions affect your answers. Try to be calm and relaxed while taking the test.



What Does MMPI-2 Measure?




The MMPI-2 measures various aspects of personality and psychopathology through a number of validity and clinical scales. The validity scales assess the accuracy and honesty of the test-taker, while the clinical scales assess the presence and severity of various psychological disorders.


Validity Scales




The validity scales are designed to detect different response styles that may affect the validity of the test results. The validity scales are:


L Scale (Lie)




This scale measures the tendency to present oneself in a favorable or socially desirable way. It consists of 15 items that most people would agree with, such as "I have never told a lie" or "I like everyone I know". A high score on this scale indicates that the test-taker may be lying or faking good on the test.


F Scale (Infrequency)




This scale measures the tendency to give unusual or exaggerated responses. It consists of 60 items that most people would disagree with, such as "I have often wished I were a girl" or "I believe I am being plotted against". A high score on this scale indicates that the test-taker may be faking bad, malingering, or experiencing severe psychopathology on the test.


K Scale (Correction)




This scale measures the tendency to be defensive or deny one's problems. It consists of 30 items that reflect common human weaknesses or faults, such as "I am easily embarrassed" or "I sometimes feel resentful when I don't get my way". A high score on this scale indicates that the test-taker may be minimizing or hiding their difficulties on the test.


Other Validity Scales




The MMPI-2 also includes several other validity scales that measure specific response styles, such as:


  • The Variable Response Inconsistency (VRIN) Scale, which measures the tendency to answer inconsistently or randomly.



  • The True Response Inconsistency (TRIN) Scale, which measures the tendency to answer mostly true or mostly false regardless of the item content.



  • The Back F (Fb) Scale, which measures the tendency to give unusual or exaggerated responses in the latter half of the test.



  • The Infrequency-Psychopathology (Fp) Scale, which measures the tendency to give unusual or exaggerated responses that are indicative of psychopathology.



  • The Infrequency-Correction (F-K) Index, which measures the difference between the F and K scales and reflects the overall validity of the test profile.



  • The Symptom Validity (FBS) Scale, which measures the tendency to exaggerate symptoms of physical or psychological injury.



Clinical Scales




The clinical scales are designed to measure different dimensions of personality and psychopathology. The clinical scales are:


1 Scale (Hypochondriasis)




This scale measures the tendency to complain about physical ailments and health problems. It consists of 32 items that reflect somatic symptoms, such as "I have chest pains several times a week" or "I am troubled by headaches almost every day". A high score on this scale indicates that the test-taker may be experiencing hypochondriasis, anxiety, depression, or somatization disorder.


2 Scale (Depression)




This scale measures the tendency to experience depressive symptoms and mood. It consists of 57 items that reflect emotional distress, such as "I often feel hopeless about the future" or "I have crying spells or feel like it". A high score on this scale indicates that the test-taker may be experiencing depression, dysthymia, or bipolar disorder.


3 Scale (Hysteria)




This scale measures the tendency to experience conversion reactions and emotional instability. It consists of 60 items that reflect somatic and psychological symptoms, such as "My hands and feet are usually cold" or "I am easily hurt by ridicule or the slighting remarks of others". A high score on this scale indicates that the test-taker may be experiencing hysteria, conversion disorder, or borderline personality disorder.


Other Clinical Scales




The MMPI-2 also includes several other clinical scales that measure specific dimensions of personality and psychopathology, such as:


  • The 4 Scale (Psychopathic Deviate), which measures the tendency to deviate from social norms and expectations.



  • The 5 Scale (Masculinity-Femininity), which measures the tendency to endorse stereotypical masculine or feminine interests and behaviors.



  • The 6 Scale (Paranoia), which measures the tendency to experience suspiciousness, persecution, and delusions.



  • The 7 Scale (Psychasthenia), which measures the tendency to experience anxiety, obsessions, compulsions, and phobias.



  • The 8 Scale (Schizophrenia), which measures the tendency to experience disorganized thinking, bizarre behavior, and hallucinations.



  • The 9 Scale (Hypomania), which measures the tendency to experience elevated mood, energy, and impulsivity.



  • The 0 Scale (Social Introversion), which measures the tendency to be shy, withdrawn, and socially uncomfortable.



How to Interpret MMPI-2 Results




The MMPI-2 results are usually presented in a graphical form called a profile. The profile shows the test-taker's scores on each of the validity and clinical scales. The scores are plotted on a standard scale ranging from 0 to 120, with a mean of 50 and a standard deviation of 10. The profile also shows the norm group's scores for comparison.


The interpretation of the MMPI-2 results should be done by a qualified professional who has training and experience in using the test. The interpretation should also take into account the test-taker's background, history, situation, and goals. The interpretation should not rely solely on the numerical scores or profile patterns, but also on the qualitative analysis of the individual items and responses.


Some guidelines and cautions for interpreting MMPI-2 results are:


Score Ranges




The score ranges for MMPI-2 scales are generally classified as follows:


  • Normal range: Scores between 30 and 70 are considered within the normal range for most scales. They indicate that the test-taker's personality or psychopathology is similar to that of the norm group.



  • Elevated range: Scores between 70 and 100 are considered elevated for most scales. They indicate that the test-taker's personality or psychopathology is different from that of the norm group and may suggest some problems or concerns.



  • Extreme range: Scores above 100 are considered extreme for most scales. They indicate that the test-taker's personality or psychopathology is significantly different from that of the norm group and may suggest severe problems or disorders.



Profile Patterns




The profile patterns for MMPI-2 scales are generally classified as follows:


  • Valid profile: A valid profile indicates that the test-taker answered honestly and consistently on the test. A valid profile usually has low scores on most validity scales and moderate scores on most clinical scales.



  • Invalid profile: An invalid profile indicates that the test-taker answered dishonestly or inconsistently on the test. An invalid profile usually has high scores on one or more validity scales and low or high scores on most clinical scales.



  • Flat profile: A flat profile indicates that the test-taker answered similarly on all items regardless of their content. A flat profile usually has low scores on all scales.



  • Spike profile: A spike profile indicates that the test-taker answered differently on some items depending on their content. A spike profile usually has one or more high scores on specific scales.



  • Codetype profile: A codetype profile indicates that the test-taker answered in a way that reflects a specific combination of personality traits or psychopathology. A codetype profile usually has two or more high scores on related scales.



Limitations and Challenges




a powerful tool that can provide valuable information about a person's psychological state, but it also has some limitations and challenges that should be considered. Some of the limitations and challenges are:


  • The MMPI-2 is not a diagnostic tool. It does not provide a definitive diagnosis of any mental disorder. It only provides an indication of the presence and severity of various symptoms and traits that may be associated with different disorders.



  • The MMPI-2 is not a comprehensive tool. It does not measure all aspects of personality and psychopathology. It only measures those aspects that are relevant for clinical assessment and screening. There may be other factors that are not captured by the MMPI-2 that may influence a person's psychological state.



  • The MMPI-2 is not a static tool. It reflects a person's psychological state at the time of taking the test. It may not reflect a person's psychological state at other times or in other situations. A person's psychological state may change over time or in response to different events or interventions.



  • The MMPI-2 is not a culture-free tool. It is based on the norms and values of the U.S. population. It may not be valid or reliable for people from different cultural backgrounds or contexts. The test items and scales may have different meanings or implications for people from different cultures.



  • The MMPI-2 is not a foolproof tool. It can be affected by various factors that may compromise its validity and reliability. These factors include the test-taker's motivation, mood, attitude, reading ability, comprehension, response style, and test-taking strategies.



Conclusion




The MMPI-2 is a widely used and researched clinical assessment tool that helps diagnose mental health disorders. It is also used in non-clinical settings to screen candidates for high-risk public safety positions and in forensic settings to evaluate legal issues. The MMPI-2 consists of 567 true-false questions that measure various aspects of personality and psychopathology through a number of validity and clinical scales.


The MMPI-2 results are presented in a graphical form called a profile, which shows the test-taker's scores on each scale. The interpretation of the MMPI-2 results should be done by a qualified professional who has training and experience in using the test. The interpretation should also take into account the test-taker's background, history, situation, and goals.


The MMPI-2 is a powerful tool that can provide valuable information about a person's psychological state, but it also has some limitations and challenges that should be considered. The MMPI-2 is not a diagnostic, comprehensive, static, culture-free, or foolproof tool. It is only one source of information that should be integrated with other sources of information to form a holistic and accurate picture of a person's psychological state.
