Overt–Covert dimension refers to an independent dimension which consist of a continuum of anti-social behavior ranging from overt forms such as physical aggression at one end, to covert forms, that is, hidden or sneaky acts at the other. The overt forms of anti-social behavior correspond roughly to those on the aggressive sub-dimension of the externalizing dimension, whereas the covert behaviors correspond roughly to those on the delinquent sub-dimension of the externalizing dimension.
