For me it depends on the individual instrument - some are more sensitive in that regard than others. I have a few instruments that never seem to need to have their truss rods touched (or will go for years between needing adjustments) and others that move around more.

I suspect it has to do with not only how stiff the neck of the wood happens to be, but also how much the top responds to seasonal changes.

I know it's mainly the response of the top that affects the movement on my mandolins. These typical require setups twice a year: once when the snow on the ground has come to stay, and again in the spring when the snow has gone to stay.

So it depends on the instrument itself, to a very large measure.
