adolescent’s developmental history and psychiatric functioning. Although informed written consent was required from parents/legal guardians of adolescents younger than age 18 years, parents/legal guardians were not required to participate in the study. This approach was chosen to allow recruitment of youth whose parents/legal guardians were unavailable or unwilling to participate in the project. Parent data, typically provided by the adolescent’s mother (91.3% of cases), were obtained for 49.2% of adolescents. Participants and parents/legal guardians who took part in the study were compensated for their participation.
