RCASA Saturday with Case Management: Sexual Abuse and the Intellectually Disabled Poplulation

What is an intellectual disability?

Intellectual disability also known as mental retardation, is a term used when there are limits to a person’s ability to learn at an expected level and function in daily life.  Levels of intellectual disability vary greatly in chidren-from very slight problem to a very severe problem.  Children with intellectual disability might have a hard time letting others know their wants and needs, and taking care of themselves.  Intellectual disability could cause a child to learn and develop more slowly than other children of the same age.  Intellectual disability can be caused by a problem that starts any time before a child turns 18 years old-even before birth.  It can be caused by injury, disease, or a problem in the brain.  For  many children, the cause of their intellectual disability is not known.

How often do adults and children experience sexual violence?

Studies consistently demonstrate that people with intellectual disabilities are sexually victimized more often than others who do not have a disability (Furey, 1994).  For example, one study reported that 25 percent of girls and women with intellectual disabilities who were referred for birth control had a history of sexual violence (Sobsey, 1994).  Other studies suggest that 49 percent of people with intellectual disabilities will experience 10 or more sexually abusive incidents (Sobsey & Doe, 1991). 

Any type of disability appears to contribute to higher risk of victimization but intellectual disabilities, communication disorders, and behavioral disorders appear to contribute to very high levels of risk, and having multiple disabilities (e.g., intellectual disabilities and behavior disorders) result in even higher risk levels (Sullivan & Knutson, 2000).

Children with intellectual disabilities are also at risk of being sexually abused.  A study of approximately 55,000 children in Nebraska found that children with intellectual disabilities were 4.0 times as likely as children without disabilities to be sexually abused. (Sullivan & Knutson, 2000).


Women are sexually assaulted more often when compared to men whether they have a disability or not, so men with disabilities are often overlooked.  Researchers have found that men with disabilities are twice as likely to become a victim of sexual violence compared to men without disabilities (The Roeher Institute, 1995). 

Why is sexual violence so common among people with intellectual disabilities?

People with severe intellectual disabilities may not understand what is happening or have a way to communicate the assault to a trusted person.  Others with a less severe disability may realize they are being assaulted, but don’t know that it’s illegal and that they have a right to say no.  Due to threats to their well-being or that of their loved ones by the abuser, they may never tell anyone about the abuse, especially if committed by an authority figure whom they learn not to question.  In addition, they are rarely educated about sexuality issues or provided assertiveness training.  Even when a report is attempted, they face barriers when making statements to police because they may not be viewed as credible due to having a disability (Keilty & Connelly, 2001).

 What risk factors contribute to the occurrence of sexual violence?

Some risk factors may include a feeling of powerlessness, communication skill deficits and inability to protect oneself due to lack of instruction and/or resources.  Individuals may live in over-controlled and authoritarian environments, contributing to the feeling of powerlessness over their situation.  In addition, they are not given enough experiential opportunities to learn how to develop and use their own intuition (those who are taught can often detect between safe versus unsafe situations.) 

Other factors include the caretaker’s failure to 1) request information on the background of all those involved in the person’s life, such as professionals, paraprofessionals, ancillary and volunteer staff,  2) become familiar with the abuse-reporting attitudes and practices of the agency, and 3) assure there is a plan in place for responding to reports of abuse when they occur.  Also, offenders are typically not caught and/or held accountable for these crimes, which allows abuse to continue.

Who is most likely to sexually assault?

As is the case for people without disabilities who experience sexual violence, perpetrators are often those who are known by the victim, such as family members, acquaintances, residential care staff, transportation providers and personal care attendants.  Research suggests that 97 to 99 percent of abusers are known and trusted by the victim who has intellectual disabilities.  While in 32 percent of cases, abusers consisted of family members or acquaintances, 44 percent had a relationship with the victim specifically related to the person’s disability (such as residential care staff, transportation providers and personal care attendants).  Therefore, the delivery system created to meet specialized care needs of those with intellectual disabilities contributes to the risk of sexual violence (Baladerian, 1991).   

What are the effects of sexual violence on someone with intellectual disabilities?

Sexual violence causes harmful psychological, physical and behavioral effects (see chart on front page).  The individual may become pregnant, acquire sexually transmitted diseases, bruises, lacerations and other physical injuries.  Psychosomatic symptoms often occur, such as stomachaches, headaches, seizures and problems with sleeping.  Common psychological consequences include depression, anxiety, panic attacks, low self-esteem, shame and guilt, irrational fear, and loss of trust.  Behavioral difficulties include withdrawal, aggressiveness, self-injurious and sexually inappropriate behavior (Sobsey, 1994).

What type of treatment or therapy is available for victims of sexual violence?

In the past the benefit of psychotherapy for people with intellectual disabilities was questioned, as well as the impact of sexual violence (whether or not it impacts people with intellectual disabilities as strongly as others without disabilities).  Today, however, it is widely acknowledged that all people who experience sexual violence are affected and do require therapeutic counseling, even if they are non-verbal.

Locating a qualified therapist may be difficult since the person should be trained in child/adult sexual abuse and sexual assault treatment as well as intellectual disabilities.  The therapist should also be trained in non-verbal mind-body healing modalities that do not require an intellectual processing component of the therapy.  Payment for the therapy can be obtained through victim witness programs, community mental health centers or developmental disability centers. 


How can sexual violence of people with intellectual disabilities be prevented?

The first step is recognizing the magnitude of the problem and facing the reality that people with intellectual disabilities are more likely to be assaulted sexually than those without disabilities.  Also, societal attitudes must change to view victims with disabilities as having equal value as victims without disabilities, and giving them equal advocacy.  Every sexual assault, regardless of who the victim is, must be taken seriously.

Secondly, sexual violence must be reported in order for repeat victimization to stop.  While few people ever disclose sexual violence for a variety of understandable reasons, such non-disclosure promotes an environment ripe for continued victimization.  Reporting can be increased by educating individuals with disabilities and service providers about sexual violence, improving the investigation and prosecution of this crime, and creating safe environments that allow victims to disclose. 

In addition, employment policies must change to increase safety.  For example, background checks on new employees should be conducted on a routine basis and those with criminal records should not be hired.  Routine checks should consistently be conducted for current employees as well.

Sex education must be provided on a regular, on-going basis, and self-determination and relationship-building skills taught so individuals with intellectual disabilities can learn how to develop safe relationships.  Classes on sexual violence should be provided to teach individuals how to respond and protect themselves when they become sexual assault victims.
