Define reliability - ANS consistency of a measure
test-retest - ANS Measuring the same individuals at two points in time and comparing results
good for behaviors that DON'T change -> remain constant
internal consistency - ANS reliability using the responses at only one point in time
good for behaviors that DO change over time
interrater reliability - ANS the correlation between the observations of different raters
Test of equivalence.
What is the Reliability and accuracy of the measures? - ANS A measure can be highly reliable
but NOT accurate
Discuss ways to establish construct validity - ANS the degree to which a test actually
measures the construct it's designed to measure

, Face validity: - ANS assessing whether a test of happiness genuinely measures levels of
happiness
Content validity: - ANS A scale for assessing anger management
Convergent validity: - ANS A French vocabulary test would have high convergent validity if
candidates who took the test would get similar scores on different French vocabulary tests.
Discriminant validity: - ANS the scores of two tests measuring security and loneliness should
not be correlated. (two Tests should not be related)
Criterion Validity - - ANS the idea that the measure is related to a specific relevant outcome.
Predictive validity- - ANS whether a test can accurately predict a particular future behavior.
Concurrent validity - ANS is present when scores on a test correlate with an already validity
measure given at the same time (concurrently).
Describe the problem of reactivity of a measure of behavior and discuss ways to minimize
Reactivity - ANS - Reactivity of a measure of behavior is a change or alteration in behavior
made due to an awareness of being observed. The change could be positive or negative
depending on the situation.
- Measure Is Reactive if Awareness of Being Measured Changes an Individual's Behavior
- Measures of Behavior Vary in Terms of Their Potential Reactivity
