Australian Temperament Project (ATP)

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 almost 40 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 at relevant time points. Parents (Generation 1) and their offspring (Generation 2) have now been followed over 3 decades (16 waves) from 4-8 months into the 30s.

Offspring of these original ATP participants were then recruited as part of the ATP Generation 3 Study. 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.

ATP will soon be described here with measure-level metadata.
