Psychological Testing Flashcards
Examples of personality tests
Myers Briggs Type Indicator (MBTI)
16 PF
Roscharch Test
Projective Test
Example of intelligence tests
WAIS, WISC, Raven’s Progressive matrices, Stanford Binet intelligence scale
Standardized vs non-standardized tests
S tests - Administered to a group that is similar to the group for whom the test is designed
NS - no standardized sampling; feedback forms
Objective vs projective tests
O test - subject expected to answer structured true/false, MCQs or rating scales; GATB, Binet intelligence scale, 16 PF
P test - unstructured; tend to elicit personal concerns; respond to ambiguous stimuli; TAT, Rorschach
Nominal scales
Assigning numbers to objects, where diff numbers represent diff objects (eg: 1 - men, 2 - women, 3 - children OR player numbers)
Numbers have no real ‘meaning’
Ordinal scales
Assigning numbers to objects, but numbers signify an order (eg: rankings)
Interval scales
Numbers have order and there are equal intervals between adjacent categories; there is equal distance between a point and the one adjacent to it
(eg: Likert scale - equal distance between ‘strongly agree’ and ‘agree’)
Ratio scales
The differences between numbers are meaningful; there is a point representing the absolute absence of the properly called ‘zero’
(eg: temp, weight)
Types of test-reliability
Test-retest reliability: Same test given on two different occasions and scores are compared
Alternate-form reliability: Two different, yet similar tests administered; more time & different tests reduce coaching effect
Internal consistency: Measure of how related the items are to each other; one answer can give an indication to how others would we answered (using half-split method or coefficient alpha)
Scorer reliability: Two or more scorers review same test; useful for subjective assessments
Validity
Degree to which test measures what it’s supposed to measure
Tests for validity
Content validation: Systematic examination of test content
Face validity: Test whether test “looks” valid to untrained observers
Concurrent validation: Used for diagnosis of an existing state (eg: is x a good therapist)
Predictive validation: Used to predict an individual’s performance in certain activities (eg: would x make a good therapist)
Self-Directed Search
Career interest test that asks questions about your aspirations, activities, skills, and interests in different jobs
Categories: Realistic, investigative, artistic, social, enterprising, conventional
Norms
Average performance on a test made by a standardized sample
Sources of error in testing
- Respondent: Honesty, fatigue, boredom
- Situational factors: Anything that can place a strain on the interview
- Measurer: Distortion of data
- Instrument: Defective measuring instrument
Ability tests
Aptitude tests: What one can accomplish through training
Achievement tests: What one can do now adequacy of learning & knowledge
