The Child to Adult Transition Study (CATS)
CATS is an ongoing metropolitan Melbourne-based longitudinal study, which began in 2012 and has followed over 1200 children from grade 3 (8-9 years of age) and beyond as they transition through adolescence, and now into young adulthood. The young people are assessed once every year. CATS has also collected information from teachers throughout primary school, as well as from parents when their children were aged 8-14 years, and again at 16-17 years.
A main focus of the study is health, emotional and educational outcomes of children as they mature through the middle years (8-14 years), navigate the biological changes associated with puberty, and transition from primary to secondary school. CATS continues to explore these outcomes for young people and their families within the changing social contexts of the secondary school years and beyond. The information collected within this large study will help us identify when and how to promote the best health and emotional adjustment in young people.
