To assess the impact of the Course for Drink Drive Offenders (CDDO) on reoffending, a treatment group of participants who had completed CDDO between January 2010 and December 2013 was compared to a matched control group.
Further analysis was completed to compare a treatment group of participants who were referred to CDDO between January 2010 and December 2013, but who did not complete the programme.
In both cases the matched control group was made up of people who had neither been referred to nor completed the course but had engaged in similar drink drive offences during this time period.
- The current analysis indicates that completing the Course for Drink Drive Offenders significantly reduced the one, two, three and four year reoffending rates of course completers compared to a matched sample of non-attending offenders.
- The differences in the one, two, three and four year reoffending rates for those who were referred but did not attend and their matched sample were not statistically significant.
