Hi Judy,
If I've learned anything from the general feedback we've been getting for this assignment, your process indicators could be something like # of clinic nurses that attend the training you hold (or completed the educational module you provide), or nurse participants' satisfaction of the training you provided, or the number of training sessions that were held (or # of emails/letters discussing the intervention that were sent) while your outcome indicators could be something like the proportion of clinic nurses that screened their patients for alcohol use and recorded that in the health record, or proportion of patients that screened positive for alcohol abuse that received referrals for further counseling (or whatever is appropriate for your target behavior).
