From Chapter 2: THE DEVELOPMENT OF THE SAM MODEL

NOTE: Please refer to the book's reference section for more than 1500 reports on childhood sexual abuse and associated topics.

ABUSE DYNAMICS

• It is estimated that 16% of boys in the United States of America will be sexually abused prior to the age of eighteen

• The vast majority of sexual abuse perpetrators are known to the child

• Across a number of studies, females account for a substantial percentage of the perpetrator population

• Among boys, the mean age at the onset of abuse is usually between 8 and 11 years

• A majority of sexually abused boys encounter abuse on a weekly basis

• The mean duration of a sexually abusive relationship extends from 2.5 to 4 years

• Boys who are subjected to childhood sexual abuse are at greater risk to be concurrently or subsequently subjected to physical abuse, psychological abuse, emotional abuse and neglect

• Threats and acts of violence are common perpetrator strategies used against boys

• The most common sexually abusive act experienced by boys is coercive receptive anal intercourse

• During a sexually abusive episode, a majority of boys have to perform oral sex on their perpetrator, fondle him or her, masturbate him or her, digitally penetrate him or her, and/or perform either penile/anal or penile/vaginal penetration on him or her

• The abuse experience is likely to remain concealed for decades, with 27 as the mean number of years between the initial episode of childhood sexual abuse and its initial disclosure

• If and when the abuse is disclosed during childhood, cases involving boys are reported, substantiated and adjudicated at significantly lower rates than cases involving girls

• A majority of mental health professionals fail to routinely inquire into the possible histories of childhood sexual abuse in their male clients and patients
