Topic: Construct Validity
Validity measures the usefulness of
a test for specific purposes. For instance, tests of depression, such
as the Beck Depression Inventory (BDI), correlate well with clinician
assessments of depression, so they can be considered valid measures of
depression. On the other hand, the BDI does not predict job performance
well, so it would be invalid for that purpose.
Types of validity include criterion-related, content, construct, and face validity.
? •Criterion-related validity looks at the correlation between test
scores and a criterion that the test scores could be expected to
predict. For instance, SAT scores for high school seniors could be
expected to correlate with their first-year college GPA.
? •Content
validity generally depends on expert opinion and looks at whether the
test adequately samples the content of interest. A math test for high
school students should sample the types of math problems that are found
in high school math textbooks and should cover the domains that high
school math teachers say are important.
? •Face validity is
important but is not validity in the technical sense. A test has face
validity if it appears to measure what it purportedly measures. For
instance, a math test for truck drivers should ask questions about gas
mileage and load weight. If it contained questions about cake recipe
proportions, it would lack face validity.
? •Construct validity is
usually accumulated over time and represents the accumulation of many
validity studies. It indicates whether the test appropriately measures a
theoretical construct.
For this Discussion, you concentrate on
construct validity. To prepare, choose a construct to use (one that was
not used in the examples) and consider how you might assess the
construct validity of a measure of that construct. Then think about how
the reliability of your measure might influence its validity.
With these thoughts in mind:
? Post a detailed description of the construct you selected.
? Then explain how you might assess the construct validity of a measure of that construct.
? Finally, explain the influence of reliability of your measure on the magnitude of its validity.
Support your response using current sources. Your post should be three solid paragraphs.
