Several author have suggested that individuals with OCD(強迫症) should report an anomalous rearing (particularly high protection)(de Ruiterm, 1994)
Rachman has proposed an " over-control" model, whereby a constitutionally predisposed "hypersensititvity" in the child is overlaid by parental over-concern and over-control, with variable expressions of the latter leading different types of OCD(強迫症). Specifically, he predicted that "cleaners' and checkers' would both describe their parents as over-cotrolling , but cleaners would also report overprotection and checkers over-criticism.
