Survey Procedures

  • [ What is IYDS?] [Project Description]  [Aims and Objectives] [Procedures] [Consent and Privacy]


    To create a detailed picture of youth development in Victoria and Washington State, the IYDS:

    • Surveyed over 150 randomly selected public and private schools from Victoria and Washington State in 2002.
    • One class per school was invited to take part in the study. Selected classes were from three year levels: Grade 5 (age 10), Year 7 (age 12) and Year 9 (age 14).
    • Approximately 1000 students at each of the three year levels in both Victoria and Washington took part in the study, giving a total of nearly 6000 students

    Information is collected from the following sources:

    Student Surveys.  Students completed a questionnaire at school in 2002, 2003 and 2004, telling us about their lives and experiences. The youngest students in the Victorian arm of our study were also surveyed again in 2006, 2007 and 2008.  Also in 2008, some students were involved in a more detailed interview which provided a richer understanding of the school environment.

    School Administrator Surveys.  An administrator at each school completed a mail survey in 2002, 2003 and 2004, providing information about their school's substance use policies and practices.

    Parent Telephone Interviews.  Parents completed a brief telephone interview in 2002, providing details on family background and parental awareness of school policies.

    Young Adult Surveys. All participants from Victoria were invited to complete a web-based survey in 2010 and 2012, and will be invited to do so again in 2014, telling us about their lives and experiences in young adulthood.

    Year 11 Teacher Survey. Year 11 teachers from IYDS schools will be asked to complete a brief survey asking about their own wellbeing, the school's student management approaches and school climate.
