Schwarz, Joel; Child Abuse Increases Risk, Oct 21 2008
Boys who experienced childhood physical or sexual abuse are more likely to use sexually coercive behavior against an unwilling female partner when they are adolescents and young adults.
The study also found that 55 percent of the men who reported coercive behavior did not experience any childhood sexual or physical abuse.
"There is a lot of evidence indicating sexual coercion and aggression is a complex behavior with an array of risk factors. There is this whole group of men for whom we have yet to fully understand what their risk factors are. They are relatively 'average' men without terrible childhood histories, but who engage in this hurtful behavior,"
