The Christchurch Health and Development Study is a longitudinal study of a birth cohort of Christchurch-born children who have been studied to the age of 30. This application seeks funding to extend this research to the age of 35. Research objectives include: a) the consequences of mental disorders for life course outcomes; b) the use, abuse and consequences of cannabis from adolescence to adulthood; c) alcohol use and antisocial behaviours; d) pregnancy, parenthood and mental health; e) the behavioural genetics of mental disorders; f) the consequences of the 2010 Canterbury earthquake; g) research from a Te Ao Maori perspective; h) the translation of research findings to policy outputs. To achieve these outcomes the cohort will be interviewed at the age of 35 on a comprehensive interview relating to social background, economic and personal circumstances, mental health and related measures.
