Firstly, I believe that it is the role of the person appraising you to fill in that form. After all, that is what is meant by appraising - they are appraising your work so they can figure out if you're a good contributer to the company.
Many companies have both you and your boss fill in separate forms, and then you both compare them to see where the areas of disagreement are.
But to answer your question:
I would think about examples at work when you are not just sitting there by yourself, but communicating to people. This would include using the phone, or walking over to another area and dealing with other people, dealing with customers, training people, working as a team with other people, receiving instructions from your boss, or letting your boss know of a problem, etc. If you consider you have some skills in that area, write them down.
Skills could be good memory, you write down notes, you are friendly, a good listener, you have an ability to understand instructions well, you help people, they come to you for help, someone has thanked you for your help, someone you trained is doing well - basically what are the good results of your communication as opposed to if you were a lousy communicator.
