What are the assumptions of self-report personality testing?. We construct items and scales that are assumed to correspond to actual subjective experiences and behaviors (content and construct validity)People are honest and insightful in responding The items must be internally consistentThe main domains of psychopathology are all tapped (personality structures, temperaments, capacities and symptoms) The tests make predictions (predictive validity).

3. Self-Report Personality Tests 1. Easy to administer, score and interpret
2. Are all easy to fake to look good or bad
3. About 15-30% of testees can fake without detection
4. More self-reports only add to the problem
5. The self report must be compared to history and current observations.
4. Types of Validity to Consider Content Validity refers to how well the item content of the scale represents all facets of a given concept.
Construct Validity refers to whether a scale correlates with a theorized psychological construct.
Validity Generalization, External Validity, Ecological Validity, Criterion validity, and Predictive Validity all deal with how well the test scores relate to the real world.
5. Should Scales Be Internally Consistent? You can’t add apples and oranges, right?
We all the sum of our parts, right?
But these are behavioral assumptions.
6. Psychoanalytic assumptions allow for internal scale inconsistencies. Behavioral assumptions demand internally consistent scales. Psychoanalytic assumptions allow for internal scale inconsistencies. Behavioral assumptions demand internally consistent scales.
7. Most of psychological and neuroscience research disproves the behavioral assumption that the mind is a blank slate written on by the environment and the sum of its parts.
8. Our brains guided us for millions of years without consciousness or rationality. Our brains have primitive parts and rational parts that are often in conflict, most of it is unconscious.
9. A self report developed from people with complex psychopathology will reflect the conflicts and contradictions of that psychopathology.
The MMPI is the only multi-trait test of various psychopathologies developed on actual criterion groups. Most other self reports were developed by the author’s theory, factor analysis, or rationally deciding on item content.
For example the Hypochondriasis scale was developed from the responses of a known group of patients with hypochondria; the Depression scale was developed from the responses of patients with major depression; the Hysteria scale was developed from the responses of patients with conversion hysteria, and so on.

11. Psychodynamic Complexity and the MMPI-2 Both the MMPI clinical scales and Psychodynamic theory reflect a psychopathology that is complex and contradictory unlike behavioral assumptions of personality as the whole as the sum of the parts.
Example: Freud (1893) observed in hysteria, psychological trauma often led to repression, pseudo-neurological symptoms, avoidance of insight, conflicts over sexuality and aggression, seductiveness and poor judgment.
12. The MMPIand the Case of Hysteria
Dahlstrom, Welsh, and Dahlstrom (1972) said of the items in the Hysteria scale, “Many of seem mutually contradictory.”
The Hysteria scale has such seemingly unrelated issues such as:
somatic complaints,
naiveté,
denial of aggressive motives,
unhappy home life
and sexual conflicts.

15. False Assumptions about Psychopathology “Gordon (2006) indicated that the RC Scales are based on false assumptions about psychopathology (i.e. that consistent items are needed to assess all psychopathologies), pointing to complex diagnostic conditions like Hysteria, Post Traumatic Stress Disorder, and Borderline Personality Disorder that are better understood with a psychodynamic formulation recognizing internal conflicts and contradictions. He indicates that a simplistic behavioral approach with an insistence on more internally consistent and distinct scales
does not produce more external validity or useful measures for many of the complex disorders found in clinical practice." (Butcher and Williams, 2009, p.13)

16. MMPI-2 Depression Subtle- Aggression Guilt
Many subtle items involve the denial of symptoms.
“At times I feel like smashing things. False.” This is a subtle item in the Depression Scale. In the context of a person who is clinically depressed, it assesses the denial of aggressive motives.
Psychoanalytic theory states that depression can be due to loss or the turning of the aggression inwards. A person may have guilt over aggressive feelings and turn aggression towards the self.
Depression-Subtle items correlate negatively to Wiggins Manifest Hostility scale (-.62), and positively with Lie (.50) and K (.48).
17. Paranoia Subtle- Splitting and Projection
An obvious item from the Paranoia Scale is:
“I believe I am being plotted against. True” (persecutory ideation).
A subtle item from the Paranoia Scale is:
“I think most people would lie to get ahead. False.” (naively trusting).
People with paranoia project the split within their own personalities on to others.
The damaged self is projected onto a devalued group, and the grandiose self is projected on to an idealized group.

ANG - Anger?
CYN - Cynicism?

PSYC - Psychoticism?
DISC - Disconstraint?
NEGE - Negative Emotionality/Neuroticism?
INTR - Introversion/Low Positive Emotionality
38. Order of interpreting scales Did the person meaningfully respond (items left blank, inconsistent responding, etc.)?
Did the person respond with a self-favorable bias (Lie, K, S), a self-unfavorable bias (F, Fp) or without bias?
If there is a self-favorable bias, is it due to the context or enduring defenses? If there is a self-unfavorable bias, is it due to symptom amplification or acute psychopathology? How did it distort the clinical scales?
Look at the main clinical scales. Look at its subscales to help understand the main clinical scales.
Look at cluster of scales on a single issue (ex. all the scales of aggression).
Look at all the elevated scales and interpolate what they all indicate.
42. Using the MMPI-2 with Other Stuff for Better Predictive Validity
43. Meehl, P. E. (1956). Wanted--a good cook-book. American Psychologist, 11(6), 263-272. The "rule-of-thumb method" for generating personality descriptions from tests involves the clinician's personal experience, skill, and creative artistry; the "cookbook method" refers to "the transition from psychometric pattern to personality description is an automatic, mechanical, 'clerical' kind of task, proceeding by the use of explicit rules set forth in the cookbook." Data are cited indicating the superiority of the "cookbook method."
44. Meehl’s 1956 Article DominatedDiagnostic Assumptions for Decades But was he right?
His results were poorly supported by other research
Almost all the research indicates that structured interviewing by a trained expert is far superior to self reports

47. Know both the DSM and PDM Psychodiagnostic Systems The best self report accounts for about 10% of the variance of personality. Structured interviewing does better. Both combined does best. That means you need to know the DSM and PDM to interview.
The DSM clearly defines Axis I symptoms. The DSM is good for clearly defined research variables. The DSM is good for assessing psychotropic medication needs.
The PDM clarifies personality organization, traits, mental capacities and then symptoms. It better classifies the complexity of personality. The PDM is better for understanding psychotherapy patients.
48. The Psychodiagnostic Battery In addition to a multi-trait personality self-report (ex. MMPI-2), use different methodologies
Document review and prior test results,
Structured psychodiagnostic interview,
Evaluator generated objective test (ex. the Shedler-Westen Assessment Procedure-200) (Shedler, & Westen, 1998),
A quantative or qualitative projective assessment (ex. Rorschach, or the patient’s distortions of the evaluator),
A brief neuropsychological screening, a memory and/or intelligence test
Collateral interviews with family, professionals, etc.
If you are unable to give a full battery, then use the most relevant test or tests along with the structured interview.

49. Summary Scales based on actual cases (MMPI) are the best for assessing complex psychopathology
Use Multi-trait tests
Use the bias scales to understand test set and defenses
Use different methodologies
Know both the DSM and PDM
Use a structured interview
History and observation and more powerful than test data.
