How 8 five-level Likert items predict next year alcohol consumption?

Dear all,

How are you?

Can anyone please shed some light on how do I go about analyzing 8 5-point Likert items in relation to next year alcohol consumption? I have a continuous variable of alcohol consumption for 2 years ie 2000 and 2001 whereas the Likert statements were asked in 2000.

I read about papers on generating polychoric correlation matrix for the Likert items and use it for common factor analysis to generate scoring coefficients for Factor1, Factor2..., and so forth. Next, score the data with this scoring coefficients.

But what will be the meaning of this new facor score variables Factor1, Factor2..., and so forth in the data? How do they be used to subsequent analysis ie regression modelling.


Thank you very much.
