Resource summary
Standards for Psychological Tests
RELIABILITY
Test-retest reliability
Administering the same measure to the same group at least twice and correlate scores
Internal consistency
All items on a test are measuring the same skill
Interjudge reliability
Consistency of measurement when different people observe the same event or score the same test
Explicit scoring instructions attribute to high inter judge reliability
VALIDITY
Construct validity
Exists when a test successfully measures the psychological construct it's designed to measure
Content validity
Whether items on a test measure all the knowledge/skills that underlie the construct of interest
Criterion-related validity
Ability of a test to correlate with meaningful criterion measures
Eg. If an intelligence test is measuring what it's supposed to, then the IQ it yields should allow us to predict behaviours influenced by intelligence
STANDARDIZATION
Development of norms
Test scores derived from a large sample provide normative scores, which is used as a basis for interpreting an individual's score
An average that gives us something to compare to
Rigorously controlled testing procedures
Static testing
Make sure testers are responding as similar a stimulus situation as possible so scores are solely a reflection of their ability
Dynamic testing
Testing is followed by feedback from the examiner on how to perform, and observes how the person uses this info
Useful for people that haven't had equal learning opportunities and aren't used to Western-styled tests
