Oh, the person in the audience gave very long explanation to the meaning of the p-values. It is simply a precision (hence confidence) in the estimate of the slope parameters for the items. I believe that the more people we have with varying degrees of ability, the more precision we would have.

I am not sure what actually your issue is, however using stata you can do group analysis
