Vinod, 

Well, usually analyzing coarse scales with OLS (or any method that assumes a continuously distributed observed response) will give you attenuated estimates (but the difference tends to vanish as the number of response categories increase). See:

Peel, M.J., Goode, M.M.H, & Moutinho, L.A. (1998). Estimating consumer satisfaction: OLS versus ordered probability models. International Journal of Commerce and Management, 8(2), 75-93.

Beauducel, A., & Herzberg, P.Y. (2006). On the Performance of Maximum Likelihood Versus Means and Variance Adjusted Weighted Least Squares Estimation in CFA. Structural Equation Modeling, 13(2), 186-203. 

However, such methods can be computationally intensive (requiring several dimensions of integration with complex models), especially in the case when latent variables are involved. You may want to see a synthesis of probit and OLS methods (POLS):
