The International Youth Development Study (IYDS) is a
long-term study that began 2002, that looks at the development of healthy and

In 2018, Victoria and Washington State will undertake
further locating and surveying with participants from the middle cohort (i.e.
those who were in year 7 when the study commenced). This will enable comparison
of the views and experiences of IYDS participants who have grown up in
Washington State with those of participants who have grown up in Victoria.
Development Research Group, University of Washington and Deakin University.
IYDS received funding from National Health and Medical
Research Council (NHMRC) 2010-2014 and the Australian Research Council (ARC) from
2010-2012. Funding to support 2018 data
collection has been received from the United States National Institute on
