Ordinal Regression vs Multinomial Logistic Regression

Katina Dimoulias
Hello,

I have a series of IV's that are ordinal - (1 not at all important, 2 not
too important, 3 neither, 4 important, 5 very important) and DV's that are
ordinal - (e.g. Seldom, Occasionally, Often).  I have been reading a lot
about both Ordinal Regression and Multinomial Logistic Regression, but I am
unsure exactly what the difference is between them and which one is the
most appropriate for my data and research questions.  I would greatly
appreciate some advice on a few questions.

What characteristics of these two analyses will help me decide which is
more suitable for my data/ how would I work out which is the most suitable?

I am also confused about creating dummy variables.  My IV categories are
coded as 1, 2, 3, 4, 5 and DV categories 0, 1, 2.  Will I need to create
dummy variables for each of the IV and DV categories and recode the
responses to 1 and 0?

Apologies if my posting is not clear.
