Eligibility: Healthy identical and fraternal, same-sex twins. Aged 30-65 years. Live in Sydney or a willing to travel to Randwick for an MRI.

This study aims to identify the psychological and brain factors that contribute towards resilience in healthy adult twins. We also aim to determine the role of genetics and environment in altering these pathways over time. By studying identical and non-identical twins, we will be able to understand more complex questions about these processes, including the factors that may protect someone from becoming mentally ill, even if they have been exposed to significant stress.

This important study has been running for more than 10 years and has made incredible discoveries. They are now seeking new participants to join. To find out the latest results from this study please view a brief summary report from the researchers HERE

What is involved?

This study involves 2 parts. Participation in each part is required.

  1. An online questionnaire which will take approximately 30 minutes to 1 hour to complete. These questionnaires will measure things such as your physical and mental health, general life experiences, mood, personality, coping styles, and emotional awareness.
  2. You will be asked to come into NeuRA at Randwick and complete a magnetic resonance imaging (MRI) brain scan. The total session will take up to 1 hour (including practice and set-up time) but the time to complete the MRI tasks will only take 30 minutes to complete. You will also be reimbursed $100 for your trip to NeuRA to cover your travel expenses.
