Recognition of the widespread incidence of overt incest in childhood has significantly increased in recent years. The described long-term effects range from severe psychopathology and behavioral disorder to mild and subtle manifestations.

Effects on ego development and function were traced, and an attempt was made to develop recognition of cues suggestive of past overt incest. The case suggests that many additional factors contribute to the final long-term effects of overt incest in childhood.
