I'm sure you can come up with an arbitrarily offbeat metric of success in medical school that doesn't correlate with MCAT. The value of the nuance depends on the face validity of that metric and how well it discriminates students.
Second, while face validity is completely irrelevant to validity as currently understood by psychometricians, it can be quite important for legal purposes, because US courts have often used face validity as a factor in their deliberations.
Another option than IQVIA would be to use the aggregate net rebate reported in pharma price transparency reports. Also problematic, but another data point. We found, these reports had some face validity compared to VA prices here: https://rdcu.be/bmncj
We love talking about petechiae above and below the nipple line in relation to meningococcal dis.
The actual evidence of this is based on a mere 200 patients..
It’s dogma that spread like a virus. Has such good face validity but is it fact
Dr. Tom Waterfield explores
First, "face validity" is not, technically speaking, an aspect of validity at all, as it is concerned with whether the test looks like it is testing what it claims to be testing, not whether it actually does so.
“FACE VALIDITY is the extent to which a test is subjectively viewed as covering the concept it purports to measure...In other words, a test can be said to have face validity if it "looks like" it is going to measure what it is supposed to measure.”
(I'm not sure if you meant "face valid" as a joke or not. FWIW, for the vast majority of tasks used in fMRI, face validity is the *only* form of validity that one could plausibly claim—and even that's usually a stretch.)
Well I think a lot of people are paying for it though... My point was: Where is face validity located? Do you have to be a non-expert on something in order to make a judgment on its face validity? If you are an expert, doesn’t that make your impression more than face-level?
I work in a rural ED with limited resources. Sure it has face validity to use mCPR in these environments. However, this way of thinking has fooled us before. Demonstrate POO before purchase of any mCPR. pic.twitter.com/Kya984GLci
