“…The overall design and conduct of the NSMHWB survey have been reported elsewhere (Australian Bureau of Statistics, 1998 a ; Whiteford, 2000). Briefly, this was a community survey of 10,641 Australians using a computerized field questionnaire, which included sections of the Composite International Diagnostic Interview (CIDI) (World Health Organization, 1994 ;Andrews & Peters, 1998) with additional survey modules screening for other disorders (Henderson et al 2000), selfratings of disability, and with self-reported service utilization and perceived needs for care (Meadows et al 2000 b, c). The Australian Bureau of Statistics produced a Confidential Unit Record File (CURF) (Australian Bureau of Statistics, 2000) containing the data set from this survey, and this file formed the basis for the analyses described in this paper.…”
