doubly manova

Hi There,

Having run an intervention study recently I now have the task of analysisng the data.

I have 2 IV's (time (pre, mid and post), group (intervention, participating control and non-participating control)

2 DV's (Physical self-worth, competence)

I have attempted to run a doubly MANOVA in SPSS. What I'm struggling with is understanding the output.

I have a significant main effect for group (btwn subs) and time (within subs) and a time x group interaction but am struggling to understand the rest inparticular the interactions.

Could anyone point me in the direction of a good (understandable) book or resource to help me?!
