Exam questions Flashcards
What does the MMPI measure?
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.
- Dimensions of personality, symptoms and behavior
What is empirical keying? How was it used in the MMPI-II?
AKA Critirian Keying - empirical determination of items that differentiated between groups; the clinical scales were derived by selecting items that were endorsed by patients known to have been diagnosed with certain pathologies.
- Test items selected or developed according to face validity
- Focus on validity: each item had to discriminate between groups successfully
What was the original standardization sample for the MMPI? NORMALS
- 724
- visitors of Univ. of Minnesota hospital and outpatient clinics
- Ages 16-65
- 1930 census
- ~35 years old
- married
- lived in small town/rural area
- 8 years schooling
- worked for skilled or semi-skilled trade or married to a man at this level
What was the original standardization sample for the MMPI? CLINICAL GROUP
- 221 psychiatric patients from univ. of mini hospitals
- all dx represented (1940s)
- No diagnostic uncertainty nor multiple d/os
- diagnostic groups in clinical scales - hypochodriasis, depression, hysteria, psychopathic deviate, psychasthenia, schizophrenia and hypomania
How reliable is the MMPI-2?
- only caucasians in orig. development
- 1980 census, still biased
- sig diff b/w caucasians and ethnic minority groups
- acculturation (t-scores 50-60 reflect issues of acculturation and t scores >65 refelct sxs and probe consistent with Caucasians
- Test re test: clinical scales.93 (Si) to .56 (Pa)
Describe the MMPI-2’s validity
Convergent, discriminant and incremental to other measures of emotional functioning
Describe threats to validity
- threats to protocol validity
- non-content-based invalid responding
- content-based invalid responding
- under-reporting
- over-reporting
what are the advantages of MMPI-2?
TBD
Describe the disadvantages of MMPI-2.
TBD
What is the age range for the MMPI-2?
18 and older
What reading level is necessary to administer the MMPI-2?
6th grade reading level
What is a clinically significant score on the MMPI-2?
> /= 65
< 40
In what way are the mean T score and standard deviation related to MMPI-2 test interpretation?
TBD
- Mean = 50; SD = 10
CNS
Cannot Say Scale
- > 10 omissions = concern for validity
- omissions possibly due to lack of cooperation and defensiveness, lack of insight, obsessiveness or reading difficulties or confusion
- Effects profile by deflating scores and depends on scale location of the omitted items
VRIN
Variable Response Inconsistency
- designed to detect Random Responding
- 47 item pairs, 12 can be scored two ways
- T scores range from 30 to 120
- Aid in the interpretation of infrequency scales
- RANDOM
TRIN
True Response Inconsistency
- designed to detect fixed responding
- 20 item pairs; 3 symmetrical (both ways)
- raw score converted to t score which will ALWAYS be =/> 50
- Detection of response sets
- Interpretation of L,K,S
- FIXED
F
Infrequency
- used to identify over-reporting
- 60 items among first 370 items
- Elevated bc: intentional (use Fp) or unintentional over-reporting, random responding (use VRIN), fixed responding (use TRIN) or sever psychopathology or severe distress
- ^F = negative info about self is being endorsed
Fb
Back (side) Infrequency
- designed to detect changes in responding between first (1-370) and second half of the test
- 40 infrequently endorsed items in second half of booklet
- Elevation= Intentional or unintentional over-reporting, random responding, fixed responding, severe psychopathology or sever distress, or fatigue
Fp
Infrequency Psychopathology
- designed to detect intentional and unintentional over-reporting in individuals with psychopatology
- 27 items endorsed infrequently by a variety of clinical samples
- elevation = intentional over-reporting, random responding, fixed responding
L
Lie
- designed to detect intentional under-reporting
- 15 obvious items
- All keyed FALSE
- Elevation = intentional under-reporting, lack of insight, very traditional values and beliefs, or indiscriminant false responding
K
Correction
- designed to detect unintentional under-reporting
- 30 subtle items
- defensive person less likely to recognize purpose and to avoid detection
- all but one keyed FALSE
- Elevation = defensiveness, denying symptoms, problems, and negative characteristics more than the avg person or psychological we’ll-being, ego strength, psychological resources
- minimal effects on education
- for clinical populations, use K-corrected scores
- for normals use non-corrected
S
Superlative Self-Presentation
- developed to identify under-reporting (Butcher and Han)
- common in personnel screening, child custody
- tendency to present highly virtuous, responsible and free of psychological problems
- subscales to help identify specific areas of defensiveness
Non-defensive with significant psychopathology
TBD
Random Responding
- F, Fb, Fp > 100
- K & S near 50
- L = 60-70
