testing repeated measures proportions

Jordan Kennedy
Hi all:

I was hoping that someone could guide me on an analysis that I would
like to run in SPSS. I have two groups (intervention vs. control) and
3 data-points (longitudinal data). I would like to determine if there
are differences between the two groups in the proportion of
individuals that have a certain disease. I was thinking that a McNemar
test would be approach but I am not sure if I can do this with the 3
time-points. Thanks for any help that you can provide.

Jordan,
 
So, subjects were measured at three time points as to whether they have a disease (0=no, 1=yes), correct? Is it possible for a subject to have the disease at time 1 but not at time 2? If yes to both, then investigate the GENLIN procedure. That is, a GEE-generalized linear model can be used to answer your research question.

A couple years ago, one of my colleagues had the same basic design.  The GENLIN syntax we used can be seen here:
