Applied Research Methods
Assessing Validity: predictive validity, face validity and content validity
- 4 things to know
- A2 Unit 4
Overview
What a validity check asks, face validity and when low face validity helps, content validity and how it is established, and predictive validity and how it would be assessed for an aptitude test.
What you need to know
Answer each one before you reveal it.
Your recallNot started
Key term
How would you assess the predictive validity of a university aptitude test?
Key term
How is face validity assessed?
Key term
A depression inventory asks only about sleep and appetite. Which type of validity is lacking, and why?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What question does every check on validity ask?
Model answer
It asks whether the measure really measures what it claims to measure, rather than something else.
- 2
Define face validity.
Model answer
It is the extent to which a measure appears, on simple inspection, to be testing what it claims to test.
- 3
How is face validity assessed?
Model answer
The items are simply read through, by the researcher or by someone unfamiliar with the topic, and judged on whether they look relevant to the concept being measured.
- 4
Why is face validity regarded as the weakest form of validity?
Model answer
Because it rests on a subjective impression of how the items look rather than on any evidence that the measure behaves as it should.
- 5
Give one situation in which low face validity is an advantage rather than a fault.
Model answer
Where the measure is meant to detect something a participant might conceal, since items whose purpose is not obvious are much harder to answer in a socially desirable way.
- 6
Define content validity.
Model answer
It is the extent to which a measure covers the full range of the concept it claims to assess, leaving no important aspect of it out.
