COMPARISON WITH THE 1997 CURF
The 2007 survey was designed to provide national estimates that can be compared internationally, rather than to provide comparisons with the 1997 survey. Due to differences in how the data were collected, care should be exercised when comparing data items from the 1997 survey with the 2007 survey. Particular attention should be given to the definition of the data item, the population, and the reference period that applies (eg 12-month versus lifetime). Differences between the two surveys are too substantial to list individually in this paper, but include changes to:
- questions and topics;
- survey methodology;
- classifications; and
Detailed information on the differences between the two surveys is provided in the National Survey of Mental Health and Wellbeing: Users' Guide, 2007
. More information about the 1997 survey is available from the National Survey of Mental Health and Wellbeing of Adults: Users' Guide, 1997
