This project aims to explore the impact of parental mental health on child mental health outcomes. Twins Research Australia members and their biological children will be invited to participate in this study to help researchers understand whether parent-child mental health impacts occur as a result of genetics or environmental mechanisms.

What is involved?

We will ask participants to complete three online survey modules including a Child Health Module, a Parent Health Module, and a Parenting Style Module. If the respondent’s oldest child is aged between:

  • 4-11 years, we will ask the parent (the twin) to report on their child’s mental health.
  • 12-17 years, we will seek the parent’s consent to approach the child and ask the child to report on his/her own mental health.

On average these three modules will take about 25-30 minutes to complete.

Who is eligible?

All female participants who completed Twins Research Australia’s Health & Lifestyle Questionnaire, who are aged 30-55 years, and their first born child are eligible to participate. To be eligible for the study, both you and your child must consent to participate.
