Genetic and environmental influences on obsessive–compulsive behaviour across development: a longitudinal twin study

摘要

BackgroundLittle is known about the factors influencing the stability of obsessive–compulsive behaviour (OCB) from childhood to adolescence. The current study aimed to investigate: (1) the stability of paediatric OCB over a 12-year period; (2) the extent to which genetic and environmental factors influence stability; and (3) the extent to which these influences are stable or dynamic across development.
