75%
What is the 12-month prevalence of mental illness in the US?

Children (8-13 yrs old)= 13%
ADHD is the most common disorder affecting children (8.5%)
What percent of adults receive treatment for mental health problems?
13.4%
What is the economic burden of treatment for mental illness?
300 billion in 2002
What is the most widely researched and used personality inventory in adult clinical samples?
MMPI-2
How was the MMPI initially developed?
- in 1943 (Hathaway and McKinley)
- Using an empirical keying approach rather than a logical keying approach with face validity
Name some main critiques of the initial MMPI?
- Adequacy of standardization sample
- Outdated and sexist language
When was the MMPI-2 developed?
1989 & utilized a large normative sample to be more representative of the US population
Do T-score values share the same meaning across MMPI scales?
No, raw scores are not normally distributed and linear T-score conversion maintains the same skewed distributions
Do T-score values share the same meaning across MMPI-2 scales?
Yes, the MMPI-2 clinical scales utilize uniform T-score conversion to ensure that skewness and kurtosis are similar across scales
T-scores across scales have an equivalent percentile and interpretive meaning
How many items does the MMPI-2 have?
567 true-false items
What age range is the MMPI-2 appropriate with?
18-84
What reading level is required for the MMPI-2?
5th grade
How long does the MMPI-2 take to complete?
60-90 minutes
What are the 9 validity scales of the MMPI-2?
Cannot say, VRIN, TRIN, F, Fb, Fp, L, K, and S
What are the 10 basic clinical scales of the MMPI-2?
Hs, D, Hy, Pd, Mf, Pa, Pt, Sc, Ma, Si
At what level do clinicians typically identify T scores on the basic clinical scales as clinically meaningful?
65 or greater
What is the first step in MMPI-2 interpretation
-Inspection of the validity scales
-Omission of 30 or more on Cannot Say scale= do not interpret
-Random or variable responding= VRIN
-Disproportionate true or false = TRIN
-Defensive resonding= L, K, S
-Exaggeration= F, Fp, Fb
Exaggeration of somatic/cog = Symptom Validity Scale and Response Bias Scale
How are the clinical scales of the MMPI-2 typically interpreted?
- Using configurations of scale elevations
- Signifies a “code type”
What is the K scale and when should the K correction be used on the MMPI-2?
- K scale: developed to identify subtle attempts to deny psychopathology
- K correction: meant to counteract defensive responding and provide more accurate understanding
- K correction should be used when employing code type interpretations
What does interpretation of the Content Scales on the MMPI-2 provide?
- Content interpretation allows the examiner to understand what emotions and attitudes have been directly communicated
- Clinical scales considers the way scale items are endorsed regardless of specific content
Why were the RC scales developed on the MMPI-2?
To improve distinctiveness of psychological constructions by removing an overall emotional complaint of distress factor that is common to the basic clinical scales (i.e., Emotional Demoralization; RCd)
What are demographic considerations of the MMPI-2?
- Older individuals show slightly higher elevations on clinical scales relevant to somatic complaints (small differences and don’t warrant age-specific norms)
- Raw score differences occur between men and woman and warrant gender-specific norms
What is the typical finding on the MMPI-2 for those undergoing various medical procedures?
- Higher clinical elevations noted on scales related to somatic complaints and physical discomfort (e.g., Hs, Hy, and RC1)
- Reactive emotional difficulties following diagnosis and treatment for emotional distress (RCd), depression (D, RC2), and anxiety (Pt, RC7)
What are some examples of conditions in which the MMPI-2 is useful in identifying somatization?
-chronic pain, persisting postconcussive sequelae, and nonepileptic seizures
What are some neurologic conditions that have been included in MMPI-2 studies?
-MS, seziures, amnestic disorder, stroke, PD, and other movement disorders
Should a “neurocorrection” be used that parses purported brain-based versus psychiatric factors on clinical scale elevations of the MMPI-2?
No, this corrupts the integrity and interpretive value of the scales and tends to underestimate the level of psychopathology.
Is the MMPI-2 useful in discriminating epileptic seizures from nonepileptic seizures?
No, research suggests a high false positive rate.
How is the MMPI-2 typically utilized in TBI samples?
- Useful in identifying premorbid psychological difficulties that are likely to account for or reinforce symptoms following mTBI
- Litigants with hisstories of mTBI produce HIGHER validity and clinical scale elevations than those with mod-severe TBI
What MMPI-2 scales are litigants and claimants most likely to show symptom exaggeration on?
Those pertaining to unusual injury complaints (FBS) and/or cognitive limitation (RBS)
What is the MMPI-RF?
- Created in 2008
- Developed to represent the clinically significant substance of the MMPI-2
How many validity and substantive scales does the MMPI-RF have?
- 9 validity scales
- 42 substantive scales: 9, RC scales from MMPI-2, 23 specific problem scales, 2 interest scales, and revisions of the 5 MMPI-2 personality psycholpathology 5 scapes (PSY-5)
What are the key test properties of the MMPI-RF?
-338 true-false items
Ages 18-83
-5th to 8th grade reading level
-35-50 min to complete
Does the MMPI-RF utilize a 2 or 3-point code type like the MMPI-2?
No, it is interpreted with three H-O scales and then specific problem scales
What are the three H-O scales of the MMPI-RF?
- Emotional/Internalizing Dysfunction (high loadings from RCd, RC2, and RC7)
- Thought Dysfunction (high loadings from RC6 and RC8)
- Behavioral/Externalizing Dysfunction (high loadings from RC4 and RC9)
How are the MMPI-RF specific problems scales divided?
-They are divided by somatic/cognitive, internalizing, externalizing, interpersonal, and interest scales
What is the age range for the normative sample of the MMPI-RF?
-18-85, similar to the MMPI-2
Does the MMPI-RF use gender based norms?
No, unlike the MMPI-2, the MMPI-RF makes use of non-gender based norms
Which subscales of the MMPI-RF bear the most relevance to symptom exaggeration of malingering?
-Similar to the MMPI2: FBS-R, RBS, and Fs
