Due to the nature of prison conditions, inmate codes, and staff attitudes, prison administrators and the general public fail to appreciate the extent and seriousness of rape in prison. Inmate rape is not primarily a sexually motivated act but instead constitutes a sexual expression of aggression that may be retaliatory, compensatory, and/or erotic. The trauma experienced by a male inmate victim of rape may be even more devastating than for a female victim since he is devalued in regard to the 2 primary sources of his male identity; sexuality and aggression. In addition, he continues to live in the same institution as his attacker. Civil litigation regarding institutional liability is increasing, and it is incumbent upon correctional institutions to train their personnel in regard to identifying, treating, and preventing inmate sexual abuse. The major features to be addressed for a model protocol are presented. (10 ref) (PsycINFO Database Record (c) 2012 APA, all rights reserved)
