Engaging Boys and Men in Sexual Assault Prevention: Theory, Research and Practice explores sexual assault prevention programs for boys and men. Following an ecosystemic perspective, the book examines individual risk and protective factors, discusses initiatives to prevent sexual aggression (i.e., bystander intervention programs, given their use among men), covers programs that specifically seek to engage boys and men in sexual assault prevention, presents key risk and protective factors for sexual aggression (i.e., healthy masculinity, rape myth acceptance), and describes the need and rationale for sexual assault prevention efforts.
