An evaluation of a single drink-driving treatment programme.

A program is described which was aimed at changing attitudes toward drinking and driving, rather than directly altering the drinking behavior of participants. The criminal records of individuals eligible to attend a drink-drivers treatment program were obtained for the period 1978-1983. Of those eligible to attend (N=381), 62 % completed the course while 38 % did not attend any session or failed to complete the program. Significant differences between these groups were not obtained for any pre-test measures, while differences were obtained between groups on the total number of crimes after treatment and the number of traffic-related violations at post-test, but not for any other outcome measure. Attendance at the course was not found to be related to subsequesnt decreases in drink-driving offences. A possible explanation for this result is that the focus of educational treatments are too broad to achieve specific behavior change for multiple drink-driver offenders. Several factors made interpretation difficult; in particular, the absence of a control or comparison treatment group. Some suggestions for overcoming this and other related methodological problems in drink-driving research are given.
