Groth (1978) presented a typology of persons who sexually assault children, which categorizes them as either “fixated” or “regressed” pedophiles. Regressed pedophiles are persons who remain fixed at a pre-adolescent level of sexual interest and who fail to find comfort or confidence in sexual relationships with partners beyond puberty. Groth defined the fixated pedophile as the typical incest offender; an individual who is not particularly interested sexually in children, but who opportunistically interacts with the child for some other reason
