Looks like an ordinal variable to me. It is always possible that the assumptions of the ordered logit model will be violated with your data, but if it works an ordinal model will be much more parsimonious than an mlogit model. If not that familiar with ordinal regression, you may wish to check out Long and Freese's book:

Dear Statalisters,

I am working with a dependent variable that has the following four potential responses: (1) Not Likely, (2) Slightly Likely,
(3) Quite Likely, (4) Extremely Likely.

A colleague thinks this is an ordinal variable which should be analyzed using ordered logit regression. My sense was that this is a nominal variable, and should be analyzed using multinomial regression - since we cannot know if the levels are
equally spaced in people's minds.

My apologies for what is probably a very simplistic question, but I've searched Statalist and online, and I still am not
entirely certain.  I would greatly appreciate input on this question.
