validity
The ability of a test to measure what it is intended to measure
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
What are the three main types of validity evidence?
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Construct, criterion, content ||\\//|| ||\\//||
What prerequisites exist for validity?
||\\//|| ||\\//|| ||\\//|| ||\\//||
reliability
Define Face Validity. How does it differ from other aspects of validity?
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
the mere appearance that a measure has validity. Face validity differs because it is not really
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
validity at all because it does not offer evidence to support conclusions drawn from test
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||

Define Content Validity: How is it measured?||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
The degree to which a test or measure adequately represents the conceptual domain it is
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
designed to measure. Measured by factor analysis and expert judgement. Not statistical,
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
logical. measures depth ||\\//|| ||\\//||
, How do construct underrepresentation and construct-irrelevant variance relate to content
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
validity?
Construct irrelevant variance = Asks questions unrelated to the construct and causes ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
variance. Ex: Did you eat a banana today? Has nothing to do with depression, decreases ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
content validity. Construct underrepresentation: Asking are you sad? Doesn't cover the
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
multifaceted nature of depression. ||\\//|| ||\\//|| ||\\//||
What is the content validity ratio and how is it measured
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Measures content validity of test items ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
- experts review and rate how essential test items are to the target construct
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
- measure of agreement among the judges
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
- items which do not meet the minimum cutoff are removed (ne = people that said it's
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
essential, closer to 1 means more essential, closer to -1 means not essential) ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
criterion
the standard against which the test is compared
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
Criterion-related Validity ||\\//||
tells us just how well a test corresponds with a particular criterion
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||
three subtypes of criterion related validity. Be able to give examples.
