Careers of offenders with an intellectual disability: the probabilities of rearrest.
Offenders with intellectual disability are rearrested far more often than other offenders, so behavior plans must target justice-system survival skills.
01Research in Context
What this study did
Cockram (2005) tracked every offender with intellectual disability for 11 years. The study compared their rearrest records to the general offender population.
This was a full-population review, not a small sample. It gives the big picture on how often people with ID return to jail.
What they found
People with intellectual disability were rearrested more often than other offenders. The gap stayed wide across the whole 11-year window.
The data say the justice system is cycling these people back through courtrooms and jails at high speed.
How this fits with other research
Kittler et al. (2004) watched a smaller group for only 10 months and also saw lots of re-offending. Their short study set the stage for this longer view.
Lindsay et al. (2004) looked only at women with ID and found lower re-offending. Cockram (2005) widens the lens and shows the overall picture is worse, proving women are the exception, not the rule.
Stancliffe et al. (2007) tracked sex offenders with ID in the community and saw lower sexual recidivism. Cockram (2005) counts every type of rearrest, so the higher rate in the 2005 paper includes property, drugs, and public-order crimes, not just sex offenses. The two studies measure different slices of the same pie.
Why it matters
If you write behavior plans, discharge summaries, or transition goals, expect rearrest risk to be high. Build in justice-system liaison, probation check-ins, and concrete skill rehearsal for police encounters. Treat recidivism as a likely behavior to prevent, not a rare setback.

03Original abstract
BACKGROUND This paper reports results from a total population of persons with intellectual disabilities (ID) in Western Australia arrested for the first time since 1 April 1984. It is part of a longitudinal study that 'tracked' offenders with ID through the criminal justice system over an 11-year period to compare their experiences at each stage of the justice process with a sample of the general offending population. The research draws on an analysis of the Western Australian Police Services Apprehension records and the Disability Services Commission database. METHOD The data collected provided the opportunity to calculate base rates of the probability of rearrest of offenders with ID in comparison to mainstream offenders. RESULTS The study found that people with ID had a significantly higher rate of rearrest than general population offenders and the study canvasses some possible reasons for this finding.
