Study Notes

Week 4 Psychometrics

Course: PSY 2234
Semester: Fall 2024

Overview

Measurement Qualities:
- Reliability
- Validity
- Standardization
Types of Measurement:
- Clinical Interviews
- Clinical Observations
- Clinical Tests
  - Projective Tests
  - Intelligence Measures
  - Response Inventories
  - Biological Measures

Measurement Implications

Tests are used for:
- Diagnosing mental illness and disability
- Creating treatment plans
- Determining which interventions work
- Awarding funding
- Hiring people for jobs
- College admissions
- Awarding places on teams
Accuracy and usefulness of tests are crucial

Reliability

The consistency and clarity of test results.
Examples:
- If a test measures extraversion, high scorers should not score low on introversion measures.
- Scores should be consistent regardless of mood.
- Similar response patterns should be found across related questions.
- The test should replicate its results.

Validity

The extent to which a test measures what it intends to measure.
Examples:
- If measuring extraversion, the test should capture its various facets (e.g., sociability, leadership).
- It should avoid measuring unrelated factors (e.g., intelligence).
- The test should have a clear definition of extraversion.
- The test should predict who might enjoy loud parties.

Standardization

Consistency in how tests are administered across various settings and administrators.
Examples:
- Consistent administration approach for participants despite questions.
- Use of English as the language for all test administrations.
- Defining whether tests are given alone or in groups, including online alternatives.

Types of Measurement (continued)

Clinical Interviews:
- Face-to-face discussions, focusing on verbal and nonverbal cues.
- Can be unstructured or structured following guidelines.
- Includes "Tell me about yourself" prompts and mental status exams.
Clinical Observations:
- Direct observation of client behavior in various contexts (e.g., natural, lab settings).
- Clinicians record and analyze behavior. Includes naturalistic observations, analog observations, and self-monitoring.
- Potential threats include observer overload or drift, and reactivity if client is self-aware of observation.
Clinical Tests: (Categorized by Validity and Replicability):
- Projective Tests (e.g., Rorschach, Thematic Apperception Test, Word Association Test, Draw-A-Person Test) - subjective, less replicable, less valid
- Intelligence Tests (e.g., IQ) - determine general mental skills. Aims to measure general ability (g), and related specifics. IQ testing usually has high stakes and is used in educational and legal contexts.
- Inventories (varied)
- Biological Measures (varied)

Projective Tests

Clinicians present ambiguous stimuli (like inkblots) to clients and record their responses.
Purpose is to infer underlying traits, attitudes, and motivations.

Intelligence Tests

Determine general mental ability, often via IQ measures.
Goal is measuring "g" (general mental ability) as well as specific skills (s).
