My gripe with some of these simple questions is that they do not provide a framework to answer the questions within.
"How often do you feel X?" With answers as "very often" means very different things to different people. For one person once a month could be very often since they expect this to never happen, while for another person a few times a day might be expected.
The problem here is that if people think that they might have a condition or be sick, it has been shown time and time again that this might emphasize the symptoms and make a person "sicker".
In addition these general questions that a lot of people can relate to will cause a lot of people to get unneeded screening, thereby straining an overloaded health service (it might be different in the US, I'm in Europe).
