Personality Assessment (cont.)
Informal personality assessments: Observation Interviewing
Formal personality assessments: Structured personality instruments Projective techniques
![Page 4: Appraisal of Personality](https://reader033.fdocuments.in/reader033/viewer/2022051821/568159a2550346895dc6f912/html5/thumbnails/4.jpg)
Informal Assessment Techniques
Observation: Most common method used Counselor biases? Reliability – unsystematic error Validity concerns
Interviewing: Diagnostic v. descriptive Quality of questions? Reliability concerns Validity concerns

Structured Personality Inventories
Methods of constructing personality inventories: Content-related procedure Personality theory Empirical criterion keying Factor analysis
Instruments most often used by counselors: MMPI-2 NEO-PI-R MBTI

MMPI-2
Criterion-keyed instruments – identification of psychopathology.
MMPI-2 norming group of 2,600 selected to match 1980 census data, but debate exists about racial bias.
MMPI-2 has 567 items to which client responds, “true,” “false,” or “cannot say.”
Contains validity scales, basic/clinical scales, content scales, and supplemental scales.

MMPI-2 Restructured Form (MMPI-2-RF)
Tellegen et al. (2003) revamped the building of clinical scales based on combining factor-analytic methods with construct-oriented scale development. Known as the Restructured Clinical Scales
MMPI-2-RF has evolved from the Restructured Clinical Scales (published in 2008) Not intended as a replacement of MMPI-2 but as
an alternative 338 items = less time to complete 50 scales = more complex interpretation

NEO-PI-R
Research suggests personality can best be described by 5 factors: I – Extroversion (or Surgency) II – Agreeableness III – Conscientiousness IV – Neuroticism (or Emotional Stability) V – Openness to Experience (or Intellect)
Factors appear to apply across diverse cultures.
NEO-PI-R operationalizes these 5 factors of personality.

NEO-PI-R (cont.)
Form S contains is self-report form; 240 items.
Form R is observer-report form of instrument; different forms for men and women.
Criticized on use for identifying pathology; normed on normal adults; based on common characteristics of personality, not pathology.
Has potential to be used cross-culturally.

Myers-Briggs Type Indicator (MBTI)
Widely-used; based on Jungian theory, for individuals 14 years and older.
Typology instrument providing scores on 4 dichotomies, resulting in individuals being categorized into one of 16 psychological types
Murphy-Meisgeir Type Indicator for Children (ages 7-12)
![Page 12: Appraisal of Personality](https://reader033.fdocuments.in/reader033/viewer/2022051821/568159a2550346895dc6f912/html5/thumbnails/12.jpg)
MBTI (cont.)
Dichotomies: Extroversion – Introversion Sensing – Intuition Thinking – Feeling Judging-Perceiving
Preferences on the 4 continuums result in a 4-letter code, producing a personality type
Criticisms: Research on whole type scores is ambiguous and
wanting Concerns about constructs being measured and
whether they are sufficient to describe the complexities and important aspects of personality

Other Standardized Personality Instruments
Sixteen Personality Factor Questionnaire (16PF) Includes measures of 16 factors and 5 global
factors Version also exists for adolescents
Jackson Personality Inventory – Revised (JPI-R) 15 subscales organized into 5 higher-order
clusters Psychometrically-sound and well-researched
![Page 14: Appraisal of Personality](https://reader033.fdocuments.in/reader033/viewer/2022051821/568159a2550346895dc6f912/html5/thumbnails/14.jpg)
Limitations of Standardized Personality Instruments
Majority are self-report instruments. Clients are able to distort results: “fake” good
or bad Risk of response sets
To increase validity of profiles: Inform client of purpose of inventory and how
results will be used Instruct client to answer each question
honestly Ask them to focus on each of the questions
![Page 15: Appraisal of Personality](https://reader033.fdocuments.in/reader033/viewer/2022051821/568159a2550346895dc6f912/html5/thumbnails/15.jpg)
Projective Techniques
Provide client with a relatively unstructured stimulus to respond to – examiner takes responses and interprets the meaning.
Psychoanalytic concept of projection – individuals’ tendency to project their own drives, defenses, desires, and conflicts onto external situations and stimuli.
Thought to uncover more of the client’s unconscious and, thus, provide an indication of the covert or latent traits.
More difficult to “fake” responses

Includes significant subjectivity in interpretation, and extensive training is needed to use these instruments.

Projective Techniques (cont.)
Strengths: More difficult to fake Can sometimes identify more complex themes
and multidimensional aspects of personality Can serve as an effective method of
establishing rapport Helpful with children and nonverbal clients
Limitations: Low reliability evidence More caution needed when interpreting results Meager validation information Lack of normative data Can be dangerous with untrained users

Self-Concept Measures
Debate and differing opinions on definition and characteristics of self-concept
Most measures relate to individuals’ evaluations of their performance or feelings about themselves
Sometimes used to obtain information on client attributes at beginning of counseling process
Used to examine effect of counseling interventions
