Variability reflects community attitudinal framing
• The moral drama of drinking driving has been the most vital force at work [RID,MADD]
• Young people have status as a “dangerous class” in America…and are a relatively weak political group. A logical safety conclusion would extend the minimum drinking age to 25 and exclude all women from such legislation. (Gusfield)
• An alcohol safety Ignition Interlock system is at the inaugural trial stage and must be seriously considered for use with recidivists (Voas)
Social control of the drinking driver (1988)
• Alcohol impaired driving is highly resistant and benefits from licence actions and intensive law enforcement with media support have been only short term
• Random Breath Testing is being trialled in New South Wales (Australia) and may have a longer effect (Snortum)
• Benefit-cost research needs to be done (Votey)
• The success of the Scandinavian system is the “per se” legislation (Andenaes)
Social control of the drinking driver (1988)
CRICOS No. 00213J
Chapter 10: Programs to Change Individual Behavior: Education and Rehabilitation in the Prevention of Drinking and Driving (1988)Robert E. Mann, Evelyn R. Vingilis, and Kathryn Stewart
• Countermeasure approaches must understand the independent and interactive influences of both personal factors and environmental factors.
• The most effective way to combat a complex social problem like drinking and driving is to introduce a set of complementary person and environment based countermeasures
• Effective social control will make judicious use of both education and rehabilitation, and environment management countermeasures such as stricter laws, random breath testing, alcohol control, improved vehicle and road design.
Effective solutions should use complementary person based (education and rehabilitation) and environment management countermeasures.

Core attitudinal messages: The drinking driver
• Canada: MADD’s mission:
• Australia: Key advertising message:
If you drink and drive you’re a bloody idiot (and if you drink and drive and don’t get caught, you’re
bloody lucky)
is to stop impaired driving and to support victims of this violent crime

4. Education & rehabilitation programs – re-visited
Key issues in rehabilitation program design
Effectiveness:• Replication of drink driving rehabilitation
program effectiveness findings in Australia, UK, EU finds between 30% and 69% reduction in recidivism with consistent replication of this outcome with high recidivist drink drivers.
• Similar findings in the USA where program was an alcohol treatment rather than drink driving intervention.
Key issues in rehabilitation program design (1)
Core elements of effective programs include: • Undertaken in addition to licence restriction and/or
suspension• Group programmes - 10 participants most common size
reported in effective programmes.• Longer rather than shorter programs (approx. 10
sessions over 10 weeks)• Interactive discussion – active learning not didactic
teaching• Use of drinking diaries and trackers to develop strategies
for high potential drink driving situations
Key issues in rehabilitation program design (2)
• Information essential but not sufficient• A focus on personally relevant strategies and skills to
avoid drink driving and group processing of problem solutions
• Staff trained to handle class relationship problems professionally
• Offenders perceive transparent and objective client selection
• A formally structured program defined by a written manual
Key issues in school-based education for senior students:Best practice (1)
Content• Material and knowledge that is consistent with the GLS (Graduated
Licensing System)
• Attitudes that are known to affect risky behaviours (e.g. attitudes to drink driving) using behaviour change theories with demonstrated effectiveness
• Road safety targets that are appropriate for the developmental stage and culturally appropriate e.g. the role of a supportive/protective peer passenger or ‘good mate’
• Emotional messages should not focus on evoking fear, and if used should be accompanied by specific coping strategies and alternative behaviours.
School-based education for senior students:Best practice (2)
Process
• Multiple sessions covering a range of issues
• Use continuity of road safety messages from primary school road safety programs through high school to licensing stage (include passenger behaviour)
• Effective messages need to be delivered through interactive processes and small group discussions
• Programs should be delivered by skilled individuals who can manage the above (e.g. teacher with relevant training)
• Ideally, include parental involvement
Driver education for senior students:Counterproductive issues
• Programs which encourage early licensing – exposure
• Programs which result in over-confidence about driving abilities in participants
• Formative evaluation to ensure program does not encourage at risk behaviours
Buckley & Sheehan (2004)
School based education for senior students
Effectiveness:• Measured by reduced drink driving in later
years rarely tested but the few that do this indicate that model programs are effective in reducing target behaviours
• Attitude and knowledge change achieved by well constructed programmes
Evaluation issues for education programs - SPIY
• Alcohol associated risk behaviours increase through adolescence

Evaluations issues for education programs –target for change
The gold standard for evaluation for drink driving school education programs is change in later drink driving offences
BUTPerhaps the change indicators should be change in the social and community context
