Eligibility: Open to twins of any zygosity, and higher order multiples (HOMs), aged one year and above. Participants must be Twins Research Australia members.

Twins and HOMs across Australia are invited to join a world-first study to rapidly measure the impact of the COVID-19 pandemic on Australians and their families.

Called TRACKERR, the Twins Research Australia COVID-19 Knowledge, Experience, Reaction and Resilience Study will investigate the pandemic’s short, medium and long-term impacts on Australian families. The study is led by Twins Research Australia based at the University of Melbourne.

The study will deliver unique and powerful insights into both genetic and environmental factors, and how they combine, to affect families’ health and experiences.

The study’s ultimate aim is to contribute to reducing the impact of the pandemic on all Australians.

What is involved?

If you agree to participate you will be asked to:

Take part in an online survey. The first survey will take approximately 20-40 minutes to complete. Follow-up surveys will be released over the coming months as restrictions are lifted and life returns to normal. Each survey will differ in length (likely to be shorter) and emphasis, as they will be designed to map how these changing times affect us all.

At all times the research results will not identify the individuals or families involved. Data linkage is confidential and is achieved by a de-identified code number linked to our research results.

Who is eligible?

If you are a twin, HOM or parent of twins/HOMs interested in joining TRA's TRACKERR study, please note:

You must be registered as a member of Twins Research Australia to participate in the study.

  1. If you are already a TRA member, please keep an eye on your inbox. Invites to adult members (18 years and above) of TRA have begun; parents of junior twins/HOMs will receive their invites in May. If you or your twin/HOM need to update your details (most importantly your email address), you can do this here.

  2. If you are NOT a TRA member, please register online here. This page includes links to adult registration and junior registration (twins/HOMs under the age of 18 must be registered by their parent or guardian). Please note: If you are already receiving communication from Twins Research Australia, you are already a member and there is no need to re-register.

All adult twin/HOM pairs (aged 18 years and above) or parents of junior twins/HOMs (aged 1-17 years) with access to complete an online questionnaire, are eligible to participate.
