Women with intellectual disability who have offended: characteristics and outcome.
Female offenders with ID rarely re-offend but almost all carry sexual-abuse trauma and mental illness, so treat the trauma first.
01Research in Context
What this study did
Lindsay et al. (2004) looked at women with intellectual disability who had broken the law. They wrote short stories about each woman to see what the group had in common.
The team noted past sexual abuse, mental illness, and whether the women got in trouble again.
What they found
Almost every woman had been sexually abused. Most also had a mental-health diagnosis.
Yet only about one in six returned to offending when prostitution was not counted. That rate is lower than many expect.
How this fits with other research
Cockram (2005) tracked both men and women with ID for eleven years and saw higher rearrest rates than in the general public. The new all-gender data seem to clash with the low female rate, but the earlier study mixed genders and used a longer follow-up.
Noordenbos et al. (2012) later added male offenders and still found women reported the highest sexual-abuse histories, backing the 2004 picture.
Lunsky et al. (2009) surveyed adult in-patients and showed women with ID carry more mood disorders and abuse records than men, matching the mental-illness side of the 2004 story.
Daigneault et al. (2023) counted substantiated abuse cases and showed children with ID are 3½ times more likely to be abused, giving a timeline that starts before the offending seen in 2004.
Why it matters
Low re-offense numbers can fool courts into thinking these women are "low risk." In truth, they need trauma care and mental-health support, not just supervision. When you write a behavior plan, add abuse-informed therapy goals and partner with counseling staff. Treating past trauma may be the best way to keep future crime, and the victim, off the books.

03Original abstract
BACKGROUND: There have been a few reports describing the characteristics and outcomes of male offenders with intellectual disability (ID). Therefore, while we are building up a reasonable picture of this client group, there are almost no reports of female offenders with ID. This paper is a preliminary attempt to present information on a small cohort of female offenders. METHODS: Characteristics of female offenders are presented including information on age, IQ, mental illness, referring agents, crimes committed, problems identified, sexual and physical abuse and outcome. Some comparisons are made with corresponding descriptions of male cohorts in Lindsay et al. (2004). RESULTS: The main result is that females constitute 9% of referrals to the service. Other notable results are that: at 61% sexual abuse in the cohort of female offenders is higher than in male cohorts but at 38.5% physical abuse is no higher than in appropriate comparison groups; as with mainstream female offenders identification of mental illness is high at 67%; and total re-offending over 5 years was 22% but, excluding prostitution, was only 16.5%. CONCLUSIONS: In some respects, this cohort of female offenders shows similar characteristics to their male counterparts. However, there are higher levels of mental illness, higher levels of sexual abuse and lower levels of re-offending. It is hypothesized that as females constitute such a low percentage of referrals, it suggests that women with ID do not show the same levels of sexually abusive behaviour or aggressive behaviour--the two most frequent reasons for male referral. Therefore, an intervening variable such as mental illness may indeed be a significant factor. Lower re-offending rates may indicate the success of interventions directed at psychological problems and mental illness.
