  1. Q10: Possible responses were Yes and No Response/Missing
  2. Q11: Possible responses were Yes, No, Not Sure, and No Response/Missing
  3. In both questions, 'missing' was a valid response for agreement analysis; separate analyses with missing values excluded (not shown) produced similar results
