Studies of consumer concerns frequently ask ''how concerned are you ab
out...?'' This question form assumes both concern and knowledge about
the issue. Using split-sample experiments, this study examined the eff
ects of alternative question forms utilizing initial filter questions
to deal with these two problems. The questions dealing with Salmonella
and Listeria bacteria were administered to a national sample of adult
women and men. The alternative forms produced lower percentages of ''
very concerned'' responses and higher percentages of ''unaware'' respo
nses. The use of the awareness filter form was found to improve correl
ations between expressed concern and information use behaviors.
