Brief report: the sexual and physical abuse histories of offenders with intellectual disability.
Sexual abuse is common in offenders with ID, especially among women and sexual-offense males—screen and plan care accordingly.
01Research in Context
What this study did
Researchers asked the adult offenders with intellectual disability about past sexual and physical abuse.
They split the group by crime type: sexual offenses versus other offenses.
Each person gave yes-or-no answers about abuse before age 16.
What they found
Men who committed sexual crimes reported childhood sexual abuse twice as often as other male offenders.
Women offenders had the highest sexual abuse rate of all groups.
Physical abuse histories were common but did not differ by crime type.
How this fits with other research
Fox et al. (2001) saw the same victim-to-offender path in child in-patients with ID.
Carter et al. (1995) first showed that sexual abuse can later show up as sexualized behavior in adults with ID.
Stancliffe et al. (2007) tracked the same adult sex-offender ID group and found low re-offense rates, so abuse history is useful for risk planning, not for predicting high recidivism.
Why it matters
When you intake an adult with ID who has committed a sexual offense, ask about sexual abuse right away.
Use the answer to choose trauma-informed supports, not to assume the person will re-offend.

03Original abstract
BACKGROUND: Some studies have found higher rates of childhood sexual abuse in sex offenders while others have failed to find such relationships. METHOD: This study reviews the sexual and physical abuse histories of 156 male sex offenders with intellectual disability (ID), 126 non-sexual male offenders with ID and 27 female offenders with ID. RESULTS: Sexual offenders reported a higher rate of sexual abuse in childhood than non-sexual male offenders (32.6% vs. 17.8%), while the opposite was true for non-accidental injury (16.0% vs. 32.5%). Female offenders reported the highest rates of sexual abuse in childhood (59.3%). CONCLUSIONS: Some specificity of childhood abuse was evident in the male cohorts suggesting limited evidence of a developmental pathway to offending, while the women were a group highly vulnerable to all forms of abuse.
