Abstract
The use of short questions in population surveys can
provide valuable information on food habits and how
these habits change. In order to monitor trends in diet and
make comparisons, standardised survey questions must
be maintained over time. However, occasionally it may be
desirable to replace older questions with improved ones.
This study was commissioned by the NSW Adult Health
Survey Program to compare the responses provided to older
and more recent versions of questions to improve the data
collected in health surveys on food habits.
