Comments and ideas
The data stems from datacollection during pregnancy and 2 postal follow-ups, one when the child was 15-18 years old filled out by the mothers (2002), and one when the child was 18-21 years old, filled out by themselves (2005). We have English versions of the questionnaires that can be downloaded from the website of our department.
