IMAGEN Study
IMAGEN recruited 14-year-old participants from high schools in the four study sites in England, France, Germany, and Ireland. To increase ethnic homogeneity in the sample, areas with minimal ethnic diversity were selected as recruitment sites. Eligible participants were recruited from private, state-funded and specialist schools to maximise socioeconomic, emotional and cognitive diversity within the sample. At baseline, the cohort included 2,000 adolescent participants.
