Comprehensive Personality Assessment Notes

Definitions of Personality

• Multiple, often conflicting definitions exist; ranging from all-inclusive (McClelland, Menninger) to highly specific or theory-bound (Goldstein, Sullivan).

• For this course:

  • Personality = “an individual’s unique constellation of psychological traits that is relatively stable over time.”

  • Inclusive of values, interests, attitudes, worldview, acculturation, sense of humor, cognitive/behavioural styles, and personality states.

• Persistent elusiveness parallels the difficulty of defining intelligence.

Personality Assessment Overview

• Personality assessment = measurement/evaluation of traits, states, values, interests, attitudes, worldview, acculturation, humour, cognitive/behavioural style, etc.

• Methods covered in two-chapter sequence:

  • Ch. 11: process, conceptual background, test construction approaches.

  • Ch. 12: specific methods (objective, projective, behavioural).

Traits, Types, and States

Personality Traits

• No single consensus; historically viewed as real structures (Allport, Holt, Cattell) vs. attributions (authors’ preferred stance).

• Guilford’s definition: “any distinguishable, relatively enduring way in which one individual varies from another.”

  • “Distinguishable” = behaviours labelled by different trait terms must differ.

  • Context matters: same behaviour can be labelled differently depending on situation (friendly vs rude example).

  • “Relatively enduring” acknowledges situational variability (violent parolee with officer vs friends).

• Cross-situational consistency imperfect (Allport quote); meta-analysis (Roberts & DelVecchio 2000) shows trait consistency increases step-wise, peaking at ages $50\text{–}59$.

• Behavioural measures: naturalistic observation, self-report, etc.

• Critics (Mischel et al.) cite lack of consistency in honesty, punctuality, conformity, etc.; situational pressures and cultural roles complicate.

Personality Types

• Type = constellation of traits resembling a defined category.

• Classical typologies: Hippocrates (melancholic, phlegmatic, choleric, sanguine).

• Jung’s typology → Myers-Briggs Type Indicator (MBTI); preferences in perceiving/judging → reactions, interests, motivations; popularity despite reliability/validity concerns.

• Holland’s RIASEC six types: Realistic, Investigative, Artistic, Social, Enterprising, Conventional; operationalised via Self-Directed Search (SDS).

• Friedman & Rosenman’s cardiology typology: Type A (competitive, time-urgent, dominant) vs Type B (mellow); Jenkins Activity Survey (JAS).

• MMPI profiles (e.g., “2–4–7”) function as type descriptions; profile = narrative/graph/table of targeted characteristics.

• Ethical/Practical note: benefits and dangers of typing (stereotyping, misclassification).

Personality States

• Two usages:

  1. Psychoanalytic (id–ego–superego dynamics via free association, dream analysis, etc.).

  2. Contemporary: transitory manifestation of traits; temporary predispositions.

• State-Trait Anxiety Inventory (STAI) distinguishes state anxiety (“right now”) vs trait anxiety (“generally feel”); test–retest supports greater stability for trait.

Personality Assessment: Referral Questions & Applications

• Employment fit, military/police suitability, academic adjustment, psychotherapy diagnosis, neuropsychological impact.

• Research uses: health knowledge, relationship commitment, team dynamics, anti-terrorism profiling, developmental trait tracking, moral judgment.

• Health links: perfectionism, self-criticism, dependency, neuroticism related to disorders.

• Corporate HR: hiring, promotion, leadership identification.

• Cross-species research (dogs, gorillas) explores environmental and genetic bases of personality (Eckardt et al. gorilla study).

Who Provides the Information?

Self-Report

• Diaries, questionnaires, computer clicks, card sorts.

• Self-concept measures (Beck Self-Concept Test, Tennessee Self-Concept Scale, Piers-Harris, Beck Youth Inventories).

  • Concept of self-concept differentiation: high vs low differentiation across roles; lower differentiation linked to psychological health.

• Response distortion:

  • “Faking good” (job apps, custody cases); “faking bad” (litigation, insanity pleas, draft evasion).

  • Insight limitations (medical/psych conditions) vs rich self-awareness.

Informant Reports

• Parents, teachers, spouses supply ratings (Personality Inventory for Children—PIC-2).

• Rater biases: leniency/generosity error, severity error, error of central tendency, halo effect, personal self-interest (Figure 11-3 cartoon).

• Inter-rater context effects: parents vs teachers (Achenbach meta-analysis), age and behaviour type influence agreement.

Cultural Context in Assessment

• Test fairness for culturally/linguistically diverse groups; examine development, administration, scoring norms.

• Concept of culturally informed psychological assessment (detailed Ch. 13).

Response Styles & Validity Scales

• Response style = characteristic answering irrespective of content.

• Table 11-1 lists: socially desirable responding, acquiescence, non-acquiescence, deviance, extreme responding, gambling/cautiousness, overly positive.

• Impression management: enhancement, denial, self-deception (Paulhus).

• Validity scales detect response styles (e.g., “I summer in Baghdad” item). Provide shorthand for honesty/diligence.

Where Assessments Occur

• Traditional: schools, clinics, hospitals, labs, HR centres.

• Naturalistic: homes, prisons, field simulations (e.g., OSS bridge rebuild, Wall Situation—Figure 11-4).

How Assessments Are Structured

Scope

• Wide-scope inventories (California Psychological Inventory 434) vs narrow scales (locus of control tests).

Theory Involvement

• Theory-saturated (Blacky Pictures—psychoanalytic) vs atheoretical (MMPI—“dust-bowl empiricism”).

Item & Task Formats (Everyday Psychometrics examples)

• True–false, like/dislike, semantic differential, forced-choice, adjective checklist, sentence completion, embedded figures, projective stimuli (inkblots, Hand Test).

• Structure continuum: highly structured handwriting copy (graphology debunked) ↔ ambiguous inkblots.

Frame of Reference

• Time/context focus influences states vs traits.

• Q-sort technique: rank-order statements; adaptable frames (actual self vs ideal self, Carl Rogers).

Scoring & Interpretation

• Simple tallies → complex computer algorithms → clinician transcripts.

• Nomothetic (universal trait continua; 16PF, Big 5) vs Idiographic (unique constellation; case study).

• Normative (compare to population) vs Ipsative (intra-individual profile).

Issues in Test Development & Use

• Self-report honesty vs insight; inclusion of validity scales debated (Ben-Porath & Waller pro; Costa & McCrae con).

• Rater training to minimise bias; language translation challenges (prudence/common sense example English–Filipino).

• Cross-cultural applicability of norms: minority elevation on MMPI scales may reflect true pathology or cultural meanings.

• Privacy vs public safety in threat assessment (Meet an Assessment Professional: Col. Rick Malone on Structured Professional Judgment; use of biopsychosocial model, warning behaviours, civil rights balance).

Methods of Personality Test Development

Content/Logic Approach

• Woodworth Personal Data Sheet (WWI screen).

Theory-Based Approach

• Items derived directly from psychoanalytic, trait, cognitive, etc. theory.

Data Reduction (Factor/Cluster Analysis)

• Example: paint-store analogy → reducing $>18{,}000$ trait words to core factors (Cattell’s 16 PF).

• Debates: Eysenck’s $3$, various Big 5 models, Waller & Zavala’s $7$.

• Big Five measured by NEO PI-R (domains & 30 facets), Big Five Inventory, TIPI, adjective markers, Five-Factor Non-Verbal Questionnaire; heritability evidence from twin studies.

Criterion-Group / Empirical Keying

• Steps: large item pool → administer to criterion vs control → item analysis → norms.

• Content need not be face-valid (Burisch “use shoe size if predictive”).

• Classic example: Minnesota Multiphasic Personality Inventory (MMPI).

MMPI Family

Original MMPI (1943)

• 566 T/F items; 10 clinical scales (Table 11-3) + 3 validity scales (L, F, K) + Cannot Say.

• Criterion groups: small $n$ inpatient diagnoses; control sample ≈1500 hospital visitors, WPA workers, students.

• Profile interpretation > single scales; methods: 2-point codes (Meehl), Welsh codes.

• Content, supplementary, Harris-Lingoes subscales.

MMPI-2 (1989)

• 567 items; modernised language, added content (drugs, suicide, work attitudes, Type A).

• New representative norms ( $n=2600$, matched to 1980 Census).

• Added validity scales: Fb, TRIN, VRIN; post-publication S scale (superlative self-presentation) and FBS (malingering) debated.

MMPI-2 Restructured Form (MMPI-2-RF, 2008)

• Motivation: overlapping items + pervasive demoralization factor.

• Tellegen et al.: created Demoralization scale + 9 RC scales, higher-order scales, 50 total scales, 338 items.

• Evidence: reduced intercorrelations, improved convergent/discriminant validity; continuing mixed findings.

MMPI-3 (2020)

• 25-50 min, $4.5$-grade reading; 72 new + 24 updated items; new norms $n=1620$; English, Spanish, Canadian French.

MMPI-A & MMPI-A-RF

• Original MMPI inappropriate for teens (elevated scores). MMPI-A (1992): 478 items, $n≈1620$ adolescent norms.

• MMPI-A-RF (2016) parallels adult RF structure; retains adolescent norms; widely used for youth psychopathology.

Personality & Culture

Acculturation

• Ongoing process shaping thoughts, behaviours, values; begins (pre-)birth via cultural agents.

• Numerous specific acculturation scales (Table 11-5) for African-American, Latino, Deaf culture, etc.; psychometric quality varies.

Values

• Instrumental vs Terminal (Rokeach); situational value taxonomies (Spranger, Kluckhohn & Strodtbeck).

Identity & Worldview

• Identification = adopting behavioural patterns of group; self-labeling reveals comfort with identity (Zuniga example: “Spanish” vs “Mexican”).

• Worldview = culturally shaped lens for interpreting experience; influences motivation, behaviour, assessment interpretation.

Interview Exploration (Table 11-6)

• 40+ sample questions probing family roles, traditions, obligations, role of work, control beliefs, spirituality, time orientation, identity, etc.

Self-Assessment Key Terms (selected)

• Response styles (acquiescence, deviance, extreme).

• Validity scales (L, F, K, VRIN, TRIN, Fb, Fs, S, FBS).

• Nomothetic vs Idiographic approaches.

• Normative vs Ipsative scoring.

• Q-sort, semantic differential, forced-choice, adjective checklist.

• Structured Professional Judgment (SPJ) vs actuarial vs unstructured threat assessment.
