Scientific title
FOllow-up and Brief Intervention of Conscripts in Lausanne, Switzerland: a single-centre randomised controlled trial
Acronym
FOBIC
Study hypothesis
Testing the effectiveness of brief interventions on alcohol, tobacco, and cannabis use and related risks outside a clinical setting and delivering it to a large majority of men in the French speaking region of Switzerland. A first phase will concentrate on alcohol use intervention, a second on tobacco, and a third on all substances addressed together.
Research questions are:
1. Are brief interventions among young men effective in reducing hazardous alcohol use and substance use in general?
2. Are booster sessions more effective than single brief intervention sessions?
3. Does a brief intervention in one domain (e.g., alcohol) show cross-effects in another domain (e.g., tobacco)?
4. Are interventions simultaneously provided for multiple risks more effective than an intervention focusing on one risk behaviour at the time?
5. Can simple assessment of problematic use (without brief motivational interviewing [BMI]) be seen as an effective minimal intervention? This can be demonstrated by comparing conscripts of the randomised trial that received
5.1. BMI with those who did not receive BMI but for which substance use was measured during assessment, and
5.2. By comparing the assessment only group with a second control group that received only screening without further assessment and without BMI

Condition
Alcohol, tobacco, and cannabis use
Intervention
This trial comprises three separate studies:
1. Study on alcohol use (600 participants)
2. Study on tobacco use (600 participants)
3. Study on the use of alcohol, tobacco and cannabis assessed together (600 participants)
Within each study, the participants will be allocated to one of the following three groups:
Group 1: Screening only (200 participants)
Group 2: Screening + assessment (200 participants)
Group 3: Screening + assessment + BMI (200 participants)
The screening questionnaire takes approximately 5 minutes to complete. The assessment questionnaire takes approximately 15 minutes to complete. BMI is intended to enforce the motivation to change behaviour. Interventions are conducted by experienced psychologists trained in motivational interviewing and in providing brief motivational interventions. Interventions last approximately 30 minutes. The same psychologists provide booster brief motivational intervention sessions 3 months after the first session by telephone. Booster sessions last approximately 20 minutes. Follow-up will be carried out at 6 months.

Primary outcome measure
Alcohol, tobacco and cannabis use 6 months after baseline, measured by the following:
1. Alcohol use:
1.1. Quantity/frequency questionnaires
1.2. Retrospective diary
1.3. Alcohol Use Disorder Identification Test
2. Tobacco use:
2.1. Quantity/frequency questionnaires
2.2. Cigarette Dependence Scale
3. Cannabis use:
3.1. First three questions of the Cannabis Use Disorder Identification Test
Secondary outcome measures
1. Reduction of related risks 6 months after baseline. Related risks are measured using several tests:
1.1. Wechsler Alcohol Consequences
1.2. Questionnaire on dinking and driving
1.3. Attitudes Towards Smoking Scale, or questionnaire for cannabis use consequences
2. Cross-over effects:
2.1. Reduction in at-risk use of tobacco and cannabis use during the alcohol study at 6 months after baseline
2.2. Reduction in at-risk use of alcohol and cannabis use during the tobacco phase at 6 months after baseline.
2.3. Substance use, measured as described above
3. Readiness to change at 6 months after baseline, measured using 10-points Visual Analogue Scale (1 = not ready to change, 10 = extremely ready to change)
