Research sample and data collection

Learn about how the study team conducts research for Ten to Men, and how participants were chosen for inclusion.

Study sample

The Ten to Men study cohort was initially recruited using a stratified, multi-stage, cluster random sample design. It selected Australian males, aged 10 to 55 from the target population based on clusters of geographical units defined by the Australian Statistical Geographic Standards (ASGS).

The sample plan was designed based on several key factors including decisions to:

  • conduct face-to-face interviews with boys aged 10 to 14 – using a simple, random sample instead of clustering would be too costly
  • oversample regional males – it was necessary to stratify the sample by region
  • adopt a household recruitment methodology – requiring defined geographical units and clustering
  • draw sample population at a national level instead of stratifying by state and territory.

Participant recruitment

To recruit study participants fieldworkers approached households in each of the chosen SA1s to determine if any residents were eligible for inclusion in the study.

Eligibility criteria included:

  • males aged 10 to 55
  • Australian citizens or permanent residents
  • sufficient English-language skills to complete the survey.

Up to 4 eligible males were invited to join the study from each household.

For wave 1, 16,021 males were recruited across 3 aged-based cohorts:

  1. boys aged 10 to 14
  2. young men aged 15 to 17
  3. adults aged 18 to 55.

Participant retention

All wave 1 participants were invited to participate in subsequent waves, but not all participants completed the survey due to withdrawal, death or other reasons. The response rates of participants for subsequent waves were:

  • wave 2 – 74% (n = 11,936; N = 16,021) 
  • wave 3 – 53.8% (n= 7,919; N=14,731) 
  • wave 4 – 48.9% (n= 7,050; N= 14,418).

Data collection

To date, 4 waves of data have been collected and a sample top-up is currently underway. Data were collected in:

  • October 2013 to July 2014 (recruitment and wave 1)
  • November 2015 to May 2016 (wave 2)
  • July 2020 to February 2021 (wave 3)
  • August to December 2022 (wave 4)
  • September 2023 to early 2024 (sample top up).
