REHABILITATION QUOTIENT (RQ) METHOD
 statistical measure of programme effects (reduced reoffending)
 conducted separately on specific rehab programmes and services
 based on rates of reconviction and re-imprisonment for new offences
within 12 months of release or programme end
 compares reconviction and re-imprisonment rates (RI) of a comparable
group of offenders who did/did not not receive that rehabilitative
programme or intervention
 percentage-point differences in rates between treatment and
comparison group = programme “effect size”
 can also be calculated based on re-offending seriousness

Offenders are matched on risk:
age, sex, ethnicity
age at first conviction
number of previous convictions
total number of sentences
total time in prison to date
summed seriousness of all
offences
• (for sex offender programmes)

MAKING BEST USE OF RESULTS
- Maintain/expand rehabilitation services that are effective
- Strengthen
programmes where outcomes are variable
- Improve matching of offenders to programme type
- Discontinue
- Pilot
ineffective services
new services to plug gaps …
