Beijing Twin Study (BeTwiSt)
BeTwiSt, established in 2006, is an ongoing study aiming to investigate the genetic and environmental etiology of adolescent psychopathology. The study has a representative sample of adolescent twins in Beijing, China (N = 1,387 pairs of adolescent twins). Participants were recruited based on a large, representative twin sample from over 600 public schools in Beijing, China.
