ATP: Australian Temperament Project
The Australian Temperament Project (ATP) is one of Australia’s oldest longitudinal studies of social-emotional development that has followed a representative sample of over 2000 infants and their parents from 4 months (1983) to over 30 years of age. The study has collected detailed age-appropriate survey data on temperament, internalising (depression/anxiety), externalising (violence and addiction) and positive developmental outcomes over 16 waves. Parents, infant welfare nurses, teachers and young people (from 11-12 years) completed questionnaires.
In 2011, we commenced recruitment of cohort offspring with follow-ups in pregnancy (T3), birth, 8 weeks, 12 months and 4 years of age, combining population surveys with in-depth clinical observations on a broad range of constructs including parent mental health and caregiving, and infant behaviour and attachment security. Bringing together data across three generations, the ATP now provides a rare opportunity to address key questions about how the experiences of one generation may affect the next, from grandparent to parent to child.

Consent is obtained to collect data at each wave. Participants are advised that their de-identified data may be shared with individuals or consortia. Participants are asked to provide consent to their child providing a cheek swab that will be held indefinitely (unless they request for it to be destroyed) and used in future ethically approved research projects related to this project. Additionally, they are asked to nominate if they they wish to be contacted if researchers would like to use their child’s DNA sample for research beyond that related to social and emotional development.
