Psychometrics

Question 1

non-standardized assessments

Answer 1

common for clinicians to use
procedures - may have to change based off client
observations - ideally use in conjunction with some standardized measure

Question 2

standardized assessments

Answer 2

built on principle of consistency
all test takers will answer same questions, graded the same way
people can piecemeal the assessments (just have to document)

Question 3

validity

Answer 3

measures what it is intended to measure

Question 4

reliability

Answer 4

consistency
same score no matter what
yielding consistent results

Question 5

ecological validity

Answer 5

degree to which the test can apply to your real life situation
degree to which an existing test is empirically related to measures of everyday functioning

Question 6

high ecological validity

Answer 6

identify real life performance issues/strengths, predicts real-world functioning

Question 7

ecological validity is crucial for

Answer 7

cognitive tests

Question 8

face validity

Answer 8

test is valid just by definition
based on intuitive judgement
ex: assess reaction time - measure how long it takes someone to react

Question 9

content validity

Answer 9

refers to whether the full content of a construct’s definition is included in the measure
are you measuring all aspects contributing to the variable that is being measured?
all aspects of the test are relevant to what you want to measure

Question 10

criterion validity

Answer 10

is the measure consistent with what we already know and what we expect

Question 11

predictive criterion validity

Answer 11

can predict a known association between the construct you are measuring and something else
ex: can performance on test A be used to predict performance on test B?
-a valid predictor on a similar test

Question 12

concurrent criterion validity

Answer 12

associated with preexisting indicators (something that already measures the same concept)
less predictive; similar result to test already validated

Question 13

construct validity

Answer 13

refers to whether the measure relates to a variety of other measures within a theory

THEORY

Question 14

interrater/interobserver

Answer 14

refers to consistent results between various testers
ex: olympic gymnastic judges

Question 15

test-retest

Answer 15

stability of the test over time
-if you take one test and a retest, you should get the same score if there has been no intervention between

Question 16

parallel forms

Answer 16

used to assess the consistency of the results of two forms of a test that are constructed in the same way from the same content domain
ex: SATs (different forms, testing same thing)

Question 17

internal consistency

Answer 17

refers to extent to which tests assess the same construct, skill, or quality (to which all items within a test are assessing the same skill, construct)
ex: vision test (all questions are about vision)
