|
||||
| When was the MMPI-2 published | show 🗑
|
||||
| show | Non-representative norms based on 724 Minnesota Normals in the 1930’s (average person was 35 years old, married with 8th grade educational level); 221 psychiatric patients (w/questionable diagnoses)

|
||||

||||
| show | Positive skew for scales since the sample was largely normal (clustered at the low or non-pathological end)
🗑
|

| show | Contains 567 items
🗑
|

🗑
|

||||
| show | MMPI-2 is for adults 18+
🗑
|

| show | 370 items of the test
🗑
|
||||
| MMPI-RF is | show 🗑
|
||||
| show | ? Cannot say, VRIN = Variable Response Inconsistency Scale, TRIN = True Response Inconsistency Scale, L = Lie Scale (pretending to be more virtuous), K = Defensiveness Scale (resisting to answer), F = Infrequency Scale (appearing more pathological then tr
🗑
|
||||
| show | MUST RULE THESE OUT TO BE VALID
1) Random Responding
2) Yea Saying (80% true responding; acquiescence)
3) Ney Saying (false responding; nonacquiescence)
4) Fake good (defensiveness, no problems at all)
5) Fake bad (exaggeration of symptoms)
🗑
|
||||
| show | 1) Evaluate acceptability/validity of the protocol
2) Examine Clinical scales for information on symptoms and personality traits
3) Examine Harris-Lingoes subscale scores to determine what components are contributing to the clinical scale elevations
4)
🗑
|
||||
| show | # of items not responded to (items left blank)
What is the reason for this?
If ? ≥ 30 invalid
11-29 examine for patterns on specific scales (10% rule for missing items)
If ? 0-10 probably valid, look at items

🗑
|
||||
| Variable Response Inconsistency Scale (VRIN) | show 🗑
|
||||
| VRIN is invalid at | show 🗑
|
||||
| show | - some inconsistency, interpret with caution, carelessness probable on test
🗑
|
||||
| show | 23 pairs of items that are opposite in content. If the persons answers T or F to both items, then a point is added to TRIN.
🗑
|
||||
| show | the direction of responding
🗑
|
||||
| show | invalid- yea saying
🗑
|
||||
| show | invalid- ney saying
🗑
|

| High (L) scores | show 🗑
|
||||
| Lie scores ≥ 80 | show 🗑
|
||||
| Lie scores less than 64 | show 🗑
|
||||
| show | can affect L scores- custody evaluations where these biases are expected; higher in clergy members
🗑
|
||||
| High L scores may reflect | show 🗑
|
||||
| show | which do not require a college education
🗑
|
||||
| If L score are elevated in highly | show 🗑
|
||||
| show | have higher L scores in general
🗑
|
||||
| Correction (K) Scale | show 🗑

| (K) All items, but one | show 🗑
|
||||
| show | 30 items
🗑
|
||||
| show | hostility, family dissent, lack of self-confidence
🗑
|
||||
| K needs to be interpreted in the context of what | show 🗑
|
||||
| show | profile may be invalid; check TRIN. If TRIN is 80F+ then the person “ney-sayed” for the test and it is invalid. If TRIN is normal, then the person adopted a defensive profile on the test; faking good profile; overly defensive attitude toward problems
🗑
|
||||
| show | the person may have attempted to fake bad
🗑
|
||||
| show | then the person “yea-sayed” for the test and it is invalid
Low K scores →If TRIN is normal
🗑
|
||||
| A very low K score can | show 🗑
|
||||
| Superlative Self-Presentation Scale (S) Developed by | show 🗑
|

| show | extremely defensive clients (airline pilot applicants) from normals - 50 items total
🗑
|
||||
| (S) correlates with which other validity scale | show 🗑
|
||||
| show | the false direction and thus, interpret with TRIN F scores
🗑
|
||||
| In clinical settings, S scores ≥ 70 | show 🗑
|
||||
| High (S) score →If TRIN F is ≥ 80, then the person tended to ney say on the test | show 🗑
|
||||
| High (S) score →If TRIN is normal, the person adopted a defensive and positive impression management approach to the test | show 🗑
|
||||
| show | 1) Random/fixed responses 2) Accurate description of acute pathology 3) Faking bad profile
🗑
|
||||
| Infrequency Scale (F) | show 🗑
|
||||

|
||||

|
||||
| (F) Minorities score how many points higher | show 🗑
|

|
||||
| F 55 - 79 | show 🗑
|
||||
| show | May be defensive
🗑
|
||||
| show | the optimal cut-score for determining faking bad (over 90) from reporting actual pathology (under 90)
🗑
|
||||
| F scores of ≥ 90 | show 🗑
|
||||
| F scores of ≥ 80 | show 🗑
|
||||
| (F) For both clinical and non-clinical samples | show 🗑
|
||||
| Back Infrequency Scale (Fb) | show 🗑
|
||||
| Fb items in the last 206 items (# 281 – 555) Changes in the test taking approach on the last part of the test If F is valid, but not Fb is invalid | show 🗑
|
||||
| F and Fb are not directly comparable scales due to | show 🗑
|
||||
| F has more what type of items vs. Fb | show 🗑
|
||||
| For clinical persons, if Fb ≥ 110 and is at least 30 points higher than F | show 🗑
|
||||
| show | interpret clinical scales only
🗑
|
||||
| show | Arbisi and Ben-Porath using 27 items that were endorsed by less than 20% of normals and persons in inpatient hospitals. So if you DO endorse them when even patients do not, then you are exaggerating
🗑
|
||||
| show | that not even normals and psychiatric patients endorsed
🗑
|
||||
| Main value of Fp | show 🗑
|
||||
| show | may be invalid
🗑
|
||||
| show | as invalid (Nichols)
🗑
|
||||
| show | check TRIN and VRIN and if over 80+ the person responded randomly or in a fixed manner to the test - invalid profile
🗑
