Scientific research

Alcohol use and substance abuse

Bjarnasson has studied adolescent alcohol use and substance abuse, comparing different European countries.

Child custody and living arrangements

In a 2005/06 international comparison of 36 western countries, Bjarnasson studied the proportion of 11-15 year old children living in different child custody arrangements. The percent of children living in intact families with both their mother and father was highest in Macedonia, Turkey, Croatia and Italy, while it was lowest in the United States, Romania, Estonia and Latvia. Among the children who did not live with both their parents, the percent in a shared parenting versus sole custody arrangement was highest in Sweden, Iceland, Belgium, Denmark, Italy and Norway, while it was lowest in Ukraine, Poland, Croatia, Turkey, the Netherlands and Romania, all with 2% or less.
