In one medical research paper, Proitsi et al. (2009) write:

"The WLSMV is a robust estimator which does not assume normally distributed variables and provides the best option for modelling categorical or ordered data (Brown, 2006)".

For your convenience, I'm including the cited reference in the reference list below (I use APA format):

Brown, T. (2006). Confirmatory factor analysis for applied research. New York: Guildford.

Proitsi, P., Hamilton, G., Tsolaki, M., Lupton, M., Daniilidou, M., Hollingworth, P., ..., Powell, J. F. (2009, in press). A multiple indicators multiple causes (MIMIC) model of behavioural and psychological symptoms in dementia (BPSD). Neurobiology Aging. doi:10.1016/j.neurobiolaging.2009.03.005

I hope this is helpful.
