Snapshot of 2022 studies


Published: Tuesday 29 November 2022

Thanks to all of our TRA members who participated in studies in 2022! Like to know more about how they are progressing? Find out below…..


  • Monash University’s Resilience and Vulnerability to Mental Health Problems Study has been a huge success in 2021 and 2022, thanks to the amazing 697 twin pairs who joined the study. The researchers are excited to continue their research with another follow-up study in 2023. Of course, they will share the results with you as these become available. Stay tuned! 
  • The long standing Twin Resilience Study (Twin-10) conducted another round of recruitment, inviting new participants to attend MRI appointments at NeuRA in Randwick, Sydney. We much appreciated the efforts of the 60 more twin pairs who joined the study.
  • The Australian Twins and Sisters Mammographic Density Study has been following up original participants of the 2005-2007 study throughout 2021 and 2022. We give thanks to the fantastic 331 twin pairs and 114 others who have re-joined the study so far. The researchers are keen to hear from any previous participants; if you haven’t yet received your invitation, please find out more here
  • TRA has partnered with GenV in 2022. GenV, short for Generation Victoria (, is the largest childhood research project ever in Australia. It is open to all Victorian children born from October 2021 to September 2023, and their parents. So far 397 multiple birth families have joined GenV. We hope all eligible TRA members will also join GenV. Please This email address is being protected from spambots. You need JavaScript enabled to view it. if you would like more information.
  • The FEASST study, which is looking into how diet affects male fertility, launched their recruitment efforts in August 2022 and will be ongoing in 2023. The study hopes to reach 25 male twin pair participants. A handful of male twin pairs have joined the study so far – a huge thanks to these pairs! If you know any male twins (identical or fraternal), aged 20-45 living in Melbourne, please let them know about this special project. It includes: $300 in reimbursement, free meals for three weeks, a detailed general and reproductive health report and a Fitbit/or one month gym membership. Learn more at  

We are excited to continue recruitment efforts for these studies and launch new studies in 2023. Stay up-to-date on our current studies page here.

Are your twin and family members missing out on TRA study invitations?

There are many twins and higher-order multiples on our database with whom we’ve lost contact. Could you help us to reconnect by encouraging them to update their email address with us? Then, they won’t miss out on invitations to exciting new studies coming up in 2023! Most of our adult studies require both twins to have valid email addresses to be invited. 

  • Parents of multiples: Have your multiple children recently turned 18? Or did they turn 18 a while ago and are not receiving correspondence from us? Parents stop receiving study invitations on their twins’ behalf once they turn 18. So it is doubly important for these twins to update their contact details if they wish to continue to participate in studies.    
  • Multiples: Does your twin or triplet(s) receive our correspondence? If not, it’s likely we don’t have a valid email for them. 

Please encourage your twin or family members to update their contact details here or This email address is being protected from spambots. You need JavaScript enabled to view it..
