Factor with only one indicator variable - does it even make sense?

Hi!
Would anyone recommend creating a factor in a CFA or Full SEM model that is only made up of a single indicator variable? I am thinking that this is as good as using the indicator directly in the model (as it is) since the loading will be very high (close to 1). Any thoughts on this will be highly appreciated.
Thanks in advance!
Hi, generally what you're
Hi,
generally what you're trying to do in factor analysis is to group a bunch of indicators together to represent a factor. So when you only have one indicator, I guess technically it's not really a factor analysis. But that shouldn't stop you from specifying a path modell/SEM. Maybe you can treat this variable as a manifest variable within your model?
