The Childhood to Adolescence Transition Study (CATS) is a
unique longitudinal study following over 1200 children as they transition
through adolescence. The study began in 2012 when children were in Grade 3 (8-9
years old) and attending primary schools in metropolitan Melbourne.
Data collection takes place annually and comprises student, parent and teacher (primary
school only) questionnaires completed online, over the phone or on paper. A
sixth wave of data collection was successfully completed in 2017 with a
participation rate of 85%. We are currently in our seventh wave, with the
majority of participants in Year 9 (14-15 years of age).
The focus of the study is on health and emotional
development through the middle years of school. CATS is interested in the
experiences of students and their families, their changing social contexts as
they move into secondary school, and the biological changes of puberty.
CATS will provide
the most comprehensive overview of the association between pubertal development
and the major health problems that become prevalent in early adolescence. The
information collected as part of this large study will help us identify when
and how to promote the best health and emotional adjustment in pre-teens.
