Australian Temperament Project

The Australian Temperament Project (ATP) is a longitudinal study of the psychosocial development of a representative sample of Australian children born in the state of Victoria between September 1982 and January 1983. The study aims to trace the pathways to psychosocial adjustment and maladjustment across the lifespan, and to investigate the contribution of personal, family and environmental factors to development and wellbeing. A major theme is the influence of an individual's temperament upon their emotional and behavioural adjustment.
