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.
Thanks,
Chelsea
