Developmental theories often assume that specific kinds of environmental risks lead to specific outcomes. Canonical Correlation Analysis was used to test whether 28 developmental outcomes (measured at 11-15 years) share the same early environmental risk factors (measured at 0-3 years), or whether specific outcomes are associated with specific risks. Data from the UK Millennium Cohort Study (N = 10,376, 51% Female, 84% White) were used. A single environment component was mostly sufficient for explaining cognition and parent-rated behavior outcomes. In contrast, adolescents’ alcohol and tobacco consumption were specifically associated with their parents’, and child-rated mental health was weakly associated with all risks. These findings suggest that with some exceptions, many different developmental outcomes share the same early environmental risk factors.
