What are the MMPI-2 clinical scales?
The validity scales vary among MMPI versions, but the MMPI-2 contains three general types of validity scales: non-responding or inconsistent responding (CNS, VRIN, TRIN) over-reporting, or exaggerating psychological symptoms, popularly called “faking bad” (F, Fb, Fp, FBS)
How many clinical scales are on the MMPI-2?
The MMPI-2 is a 567-item self-report measure of personality and psychopathology (Butcher, Graham, Ben-Porath, Tellegen, Dahlstrom, & Kaemmer, 2001), consisting of eight Validity Scales, ten Clinical Scales, and 15 Content Scales (Table 1).
Does MMPI have clinical scales?
The MMPI-2 is designed with 10 clinical scales. which assess 10 major categories of abnormal human behavior, and four validity scales, which assess the person’s general test-taking attitude and whether they answered the items on the test in a truthful and accurate manner.
What are clinical scales?
Scales of moderate accuracy used to measure patient or tissue sample mass in a clinical environment.
What is the K scale on the MMPI-2?
The K scale was derived from individuals who were hospitalized, clearly having serious psychological problems and yet producing normal profiles. They were being defensive by claiming that they had no psychological problems. High (>Raw 22).
What is the K scale on the MMPI 2?
What does the F scale measure on the MMPI 2?
The F (Infrequency) scale includes items selected to detect unusual or atypical responses. Reflecting bizarre sensations, strange thoughts, and peculiar experiences, they were answered in the deviant direction by no more than 10% of an early subsample of the normative sample.
What are validity scales MMPI-2-RF?
The two MMPI-2-RF validity scales designed to detect over-reporting of psychopathology symptoms, F-r and Fp-r, best differentiated between those classified as malingering based on the SIRS and those not so classified. Each scale added incrementally to the other in this differentiation task.
What is the L scale?
a set of items within a psychological instrument (particularly a personality assessment) used to indicate whether a respondent has been truthful in answering.
What are the cut scores for the MMPI-2?
A cutoff of 23 for men and 26 for women suggests possible malingering for the MMPI-2 (Ben-Porath, Graham, & Tellegen, 2009), which corresponds to a T-score of 80 for both cutoffs.
What is the FR scale on the MMPI-2 RF?
Results indicated large effect sizes for the MMPI-2-RF validity scales, including a Cohen’s d of . 90 for Fs in a head injury simulation sample, 2.31 for FBS-r, 2.01 for F-r, and 1.97 for Fs in a medical simulation sample, and 1.45 for FBS-r and 1.30 for F-r in identifying poor effort on SVTs.
What are the higher order scales on the MMPI 2 RF?
The RF introduces three levels of scales: a) Higher Order Scales HO, which focus on broad dimensions of psychopathology, b) nine intermediate level scales (the nine new RC scales) and c) 18 lower order or facet scales.
How to interpret MMPI-2 scores?
Gender-Based Differences. Historically, MMPI-2 protocols were interpreted by comparing a test-taker’s responses to the normative sample for his/her own gender (e.g., a male’s responses were compared to the 1138 men in the normative sample). However, the use of gender-based norms in employment-related assessments was prohibited by the 1991 U.S. Civil Rights Act. Non-gendered norms were subsequently developed (Ben-Porath & Forbey, 2003) and incorporated in the MMPI-2 materials. Non-gendered T-score conversion tables were created by randomly selecting 1138 women from the MMPI-2 normative sample, merging their data with those of the 1138 men in the sample, and recalculating the standard T scores for all MMPI-2 scales. The standard T-scores for the MMPI-2-RF are based on the same non-gendered normative sample of 2276 individuals; there are no gender-specific norms for the revised instrument.
How to read MMPI 2 scores?
-? + L = Person is trying to appear in a favorable light but uses a crude strategy to do so. -? + L + F + K = Suggests highly-generalized, intense negativism. -? + F = The profile is invalid, be it because of reading comprehension problems or mental confusion. -? + K = Test taker is very defensive.
How to interpret MMPI?
MMPI-2 Scoring & Interpretation Scores are converted to what are called normalized “T scores” on a scale ranging from 30 to 120. The “normal” range of T scores is from 50 to 65. Anything above 65 and anything below 50 is considered clinically significant and open for interpretation by the psychologist.
Is the MMPI 2 reliable?
• MMPI-2 scale scores are highly reliable over time (see the “Reliability” section of the reference list of this guide). Well-established scale reliability data support the use of the
