Participant Flow
Quasi-experimental, asynchronous study design with each site as its own control. From 2005 to 2008, 12- to 18-year-olds arriving for routine care at 9 medical offices in New England (n= 2096, 58% females) and 10 in Prague, Czech Republic (n = 589, 47% females) were recruited. Medically/emotionally stable, able to read, and available for follow-ups.
