Hi everybody. I'm trying to wrap my head around how to do a multiple regression analysis in order to analyze pathways between groups of variables. I'm attempting to prove Azjen's Theory of Planned Behavior. Basically, in it survey results about Attitudes, Behavioral Control, and Social Norms can be used to predict Intention. And Intention in turn can be used to predict Behavior alongside Behavioral Control.

Example:

Anyways, each group (Intentions for instance) consists of 5 questions that have good correlations. When I use SPSS I can't figure out how to determine how much of an effect there is from each determinant - group to the entire Intentions group. I can only figure out how to analyze multiple independent variables and a single dependent variable.

I've tried looking online, but I haven't found much yet. One example had already combined the groups, but they didn't show the descriptives so I couldn't see if they used the mean. My partner and I think it's a quick solution for someone who knows. We've thought about using the means of each group, but that doesn't feel right to me.

Any ideas?

What I mean is... sometimes you'll have a model

y = b_0 + b_1x_1 + b_2x_2

where x_1 and x_2 are both insignificant.

So you'll fit the models

y = a_0 + a_1x_1

y = d_0 + d_1x_2

and x_1 and x_2 are significant in their individual models.

Is this what you're talking about?

To be honest though... there's a very specific way to do an analysis like this and it just happens to be one of the things I haven't worked with during my time as a statistics grad student. I suggest you get some statistical consulting done.

Also not to play mod, but there's definitely a rule against asking this forum to do your homework for you. Seriously, seek a professional.

DaenrisonNot a problem, I'm just asking for general advice. I'm not asking for you to run the regression for me.

Anyways we're gonna be talking to a teacher tomorrow. I was hoping it was a quick fix though.
