LEW16. PLENARY 1 Professor David M. Fergusson (University of Otago, Christchurch) Unemployment and welfare dependence: Findings from the Christchurch Health and Development Study This presentation will use data from the Christchurch Health and Development Study (CHDS) to examine the relationships between unemployment and a wide range of psychosocial outcomes including: mental health outcomes, crime, substance use, and adverse life events. The study examined the relationship between these outcomes and unemployment in a representative birth cohort studied at ages 18, 21, 25, and 30 years. Findings of the study suggest that when due allowance was made for confounding, unemployment had weak to moderate associations with: major depression (p<.01); alcohol abuse/dependence (p<.05); property and criminal offending (p<.001); serious financial problems (p<. 01); and relationship problems (p>.10). The implications of these findings for understanding the interplay between employment and psychosocial well-being will be discussed. Part 2 of the presentation will present data on the associations between ethnicity and unemployment/welfare dependence and examine the intervening factors that place Māori at great risk of these outcomes.
