Construct Validity and Face Validity

Please help me with this question:

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.

A description of the construct of 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. Explain how you might assess the construct validity of a measure of that construct. Explain the influence of reliability of your measure on the magnitude of its validity.

Dear Student,

Hi and thank you for using Brainmass. The solution below should get you started. The question being asked here appears straightforward - basically, it asks how you would test construct validity in research. The example provided by your professor shows what construct validity is all about in the simplest terms, so exactly how would you test for that in a research? This just means reiteration of the same idea from your viewpoint and providing a sample experiment and the principles (this is what you will have to create) that you will use to analyse it for construct validity. You will have to do the same for face validity, and an example of such is provided above as well. So how should you answer this question? Let's use an outline:

1. On validity
2. On construct validity - plus example
3. On face validity - plus example
4. A creative research study - provide a sample study and then lay down the principles of validity testing you will use both for construct and for face validity
5. Conclusion

What is important is how you explain. Your professor will be looking for ideas that show you understand what this part of your lesson is all about. Just let me know via the feedback section if you need further explanation. Good luck with your studies.

On Validity

Validity is essentially the scope and capacity of the measurement of a test in that it is the notion of the relevance of the research in measuring what it is claiming (as a test) it will measure. It is not just single statistics, but the whole relationship and dynamic between the test or research and the phenomenon it is trying to make sense of (measure and explore). Consider, for example, a test claiming to measure intelligence. Is it a valid test in a sense that it really ...
