Jump to study timeline

REACH aims to investigate the impact of social, psychological, and biological risk and protective factors on the occurrence and persistence of mental health problems over time in large, ethnically diverse cohorts of adolescents recruited from secondary schools in the London boroughs of Lambeth, Southwark and Croydon. The findings from this research will provide important information on how and when to intervene to improve mental health and wellbeing among young people during this critical period.

Sample details
REACH has recruited and followed three cohorts of around 1,000 adolescents aged 11-12, 12-13, and 13-14 (around 3,000 participants in total) from around 12 secondary schools in the London boroughs of Lambeth and Southwark. All those who take part will complete a questionnaire at baseline, then again after one year (T2) and finally, after two years (T3) in class time. A sub-sample of around 180 from each cohort (total, around 540) were also recruited to complete more detailed interviews and assessments and provide biological samples at T1 and T2.
