Hello Listers,

Apologies for the remedial nature of this question, but here goes:

I'm conducting a multinomial logistic regression (3 levels of the DV) and, based on significant chi-squares/ANOVAs, would like to enter predictors hierarchically (i.e., in blocks, as in binary logistic regression and regular linear regression). On SPSS, that's not an option for multinomial; instead, you can "force entry" certain predictors and then add others in a stepwise fashion. What I'm not clear about is how to conduct this such that I force entry of specific predictors in three iterations. If this were a binary logistic regression, I would do this:

Block 1: demographic predictors (age, education) Block 2: treatment factors (treatment condition [2 levels], therapy attendance) Block 3: psychotherapy process variables (alliance, group cohesion, group similarities)

In other words, I'd like to see if/how the psychotherapy process variables predict group membership when predictors from Blocks 1-2 are controlled for. I hope this makes sense. Any advice will be appreciated.

Best, Joe
