When capitalism trumps science…this is Donald Morisky. He developed a useful tool called the Morisky Medication Adherence Scale, a questionnaire you can use to determine the likelihood someone will stick to a regimen of medication. It’s only 8 questions long, but I can see how it would be valuable.
Don’t belittle it because it’s only 8 questions, though. The hard part is validation — you’ve got to run it through a lot of trials and actually confirm its accuracy. So I expect that Morisky actually invested a lot of effort in the project.
There is some controversy over it, but that’s to be expected — it’s psychology, after all.
The tool initially involved four questions but in 2008 expanded to eight. But the paper describing the longer questionnaire was retracted in 2023 after one critic claimed the scale was no more accurate than flipping a coin.
The usual reward for this kind of research is that you publish it, you get respect and fame for it, and then researchers around the world cite your paper and you get even more well known. You get tenure. You get invited to talk at conferences about your scale. The usual.
Morisky took a different route. He published it, and then slapped a copyright on it, and allowed other researchers to use it IF they coughed up a hefty fee. The fee seems to be wildly plastic — some people get billed $500, others get a demand for $7500. Some get to use it for free.
Morisky has added a new wrinkle to his profit-making scheme: if he doesn’t get his money, he will demand that papers that used his scale be retracted.
By our count, there have been at least nine retractions for licensing issues related to the MMAS. But not all retractions of papers that use the scale explicitly cite a reason in the notice, so the number is likely higher.
Those might have been good papers, but that doesn’t factor at all into Morisky’s criterion: did they pay Morisky, or didn’t they? I call it corruption. The only responsible approach is to refuse to use the scale and to develop your own independent measures, but as I said above, that is hard work. In science, we’re supposed to be able to stand on the shoulders of those who came before us, but I guess you can’t if your predecessor was Donald Morisky.
