Plain English Summary
Background and study aims
One fifth of drivers convicted of drink-driving for the first time will be convicted again for the same offence in subsequent years. Lecture-based educational programs are believed to reduce recidivism (re-offending). The aim of this study is to measure the effects of short lectures with and without the presence of a close relative ‘in class’ on the rates of recidivism during the two years after an initial drink-driving conviction.
Who can participate?
Drivers in the Canton of Geneva convicted of a first-time drink-driving offence.
What does the study involve?
Participants are randomly allocated to attend either: a two-hour series of lectures; a one-hour lecture and a group psychological intervention with a close relative; or to receive written information on the consequences of alcohol consumption. Time until recidivism is retrieved from a national registry for two years after participation.
What are the possible benefits and risks of participating?
Participants benefit from a one-month reduction of the time for which their license is suspended. They will also personally benefit from changing their behaviour towards drink driving given the legal, financial and emotional consequences drink driving can have. There are no known risks related to the intervention.

| Scientific title | Effectiveness of an educational program for preventing drinking and driving recidivism: a randomized controlled trial |
| Study acronym | PRECASIA 2 |
| Study hypothesis | A short educational program with or without a proxy reduces the hazard of drink driving recidivism within the two first years. |
| Ethics approval(s) | Official state ethical committee (Commission cantonale d'éthique de la recherche du Canton de Genève), December 2010, ref: CER10-214 |
| Condition | First time convicted offenders for drink driving with blood alcohol concentration ≥0.8 g/kg and < to 2.5 g/kg |
| Intervention | Participants are invited to attend an educational programme on drinking and driving in exchange for a reduction, of one month, of the time for which their license is suspended. Participants are randomly assigned to either: 1. A two-hour series of lectures. Participants are informed regarding accident statistics, offence-related legal procedures, the consequences of DUI for insurance cover, the medical consequences of heavy drinking, the psychological aspects of alcohol consumption, and behavioural strategies for avoiding DUI recidivism. Class size are limited to 12 participants. Participants receive printed materials on alcohol consumption and consequences at the end of the two-hour lecture. The program is delivered by a psychologist with educational experience. The entire lecture is delivered during one morning. 2. A one-hour lecture and a group psychological intervention with a proxy. Participants are asked to choose, nominate, and bring with them a close relation (proxy) such as their spouse, a companion, or a friend. After receiving a briefer lecture, this group is to expose reasons for changes to an unknown proxy from another pair. They then have to plan a strategy for change with their original proxy. 3. The control group also receive a reduction, of one month, of the time for which their license is suspended and paid for program costs. They however only received written information on alcohol consumption and consequences. Program costs were paid by the individual drivers (CHF 200). |
