Description of intervention(s) / exposure
Preventure (Conrod, 2016) is a school-based intervention designed to prevent drug and alcohol misuse. Participating secondary schools will be randomly allocated to one of two groups. One group will serve as the control group and receive their usual Year 8 health education and the other group will receive the Preventure intervention.

Students will complete the Substance Use Risk Profile Scale (Woicik et al., 2009), a screening questionnaire previously validated in adolescents and showing good reliability and internal consistency, in Europe (Castellanos-Ryan et al., 2013), North America (Krank et al., 2011) and Australia (Newton et al., 2016). In schools allocated to the Preventure intervention, students scoring one or more standard deviations above the mean on one of four personality profiles (hopelessness, anxiety sensitivity, impulsivity and sensation seeking) as identified by the SURPS will be invited to participate in two 90-minute group workshops held at school.

These workshops incorporate components of cognitive-behavioural therapy and motivational interviewing to promote coping skills in adolescents. The focus is on motivating teenagers to understand how their personality style leads to certain emotional and behavioural reactions. Four different workshops are run, each focused on developing specialised coping skills relevant to following personality styles:

• Sensation seeking
• Impulsivity
• Anxiety sensitivity
• Negative thinking.

Student workbooks are provided to each participating student as part of the intervention. These workbooks were created by the Preventure developers and are only available to be used as part of the program. They are specific to each of the above personality types and contain exercises the group work through together during session time, which encourage students to recognise emotions and behaviours and better align these with their long-term goals. The workbooks also contain personal exercises students can complete during the session or at home, according to the facilitator and co-facilitator’s decision.

The sessions incorporate real life example scenarios and include: i) psycho-education about the specific personality style and accompanying maladaptive coping behaviours (e.g., avoidance, aggression, alcohol use); ii) development of a personalised model of the physical, cognitive and behavioural components of standard responses; and iii) motivational enhancement, goal-setting and use of cognitive-behavioural strategies to adapt problematic reactions and behaviours.

School staff delivering the intervention will receive 3 days of training by the lead CI, an approved Preventure trainer. The training will cover basic counselling skills, an understanding of the aims of the intervention, and how to implement the intervention with students. School staff will be supervised by the CI in facilitating the intervention with a separate group of students not included in the trial (in another grade), to ensure high-fidelity in delivery of the intervention. School staff will be guided through a facilitation manual during training, which they will keep and use in their implementation of the intervention. School staff will be required to complete session notes after each intervention session, to document their implementation fidelity and record any concerns.

Comparator / control treatment
Control schools will implement health education as usual in 2020. All control schools will implement curriculum-based health education during the trial (but will vary in the method of delivery), and this group will serve as an ‘active control’. Control schools will be offered complimentary use of the intervention at the end of the study in 2022.

Outcomes
Primary outcome [1] 324139 0
Alcohol use. The following measures were adapted from the School Health and Alcohol Harm Reduction Project ‘Patterns of Alcohol’ index (McBride et al., 2004): intention to try alcohol, any use of alcohol ever (at least a standard drink), the frequency and quantity of alcohol consumption in standard drinks in the past six months, and frequency of binge drinking (five or more standard drinks on one occasion) in the past six months. Alcohol-related harms will be measured with an abridged form of the Rutgers Alcohol Problem Index (RAPI) (White and Labouvie, 1989).

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be concealed. Schools will be randomly allocated to groups by an external researcher.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An external researcher will perform blocked randomisation of schools to Preventure and control, stratified by school gender mix [co-educational, predominately male (>60%), or predominately female (>60%)], using the Blockrand package in R (Snow 2020). Allocation concealment is ensured as the external researcher does not release the randomisation until the school has been irreversibly allocated to a condition. Schools will not be masked to their allocation and will be informed whether they are in the intervention or control group. As is the case for school-based interventions of this kind, schools' allocation will not be masked to students, teachers, and researchers. Students will be blinded to the hypotheses of the study.

Statistical methods / analysis
Sample size calculations:
This trial is powered to detect differences between groups in the overall sample, as well as among the students scoring above average on the SURPS personality scorer (selected students). A total of 280 selected students from 10 schools are required (i.e. 28 selected students per school and 5 schools per intervention group) to achieve 80% power to detect a standardized between-group mean difference of 0.3 (p =.05) in outcomes. A between-group effect size of 0.3 is in line with effect sizes observed in previous Preventure trials (Newton et al., 2016). To account for dropouts, we aim to recruit 12 schools at baseline (6 per group) with 75 students per school, 40% of whom are expected to be selected based on previous research (Conrod, Castellanos, & Mackie, 2008), giving a total of 900 students to test the effect of the intervention.

Statistical Analysis:
Intention-to-treat analyses will be carried out for all primary and secondary outcomes. Baseline equivalence and attrition between groups will be examined using single-level analyses; one-way analyses of variance (normally distributed data), chi-squared analyses (binominal data), and Mann-Whitney U-tests (non-normally distributed data). To examine intervention by time interaction effects, mixed effects regression will be used due to the multi-level nature of the data (students nested within schools). Hypothesised intervention effects on alcohol use, anxiety and depression symptoms will be examined using mixed effects linear regression analysis (continuous data) and mixed effects logistic regression analysis (categorical data). Missing data will be handled by full information maximum likelihood, in accordance with the intention-to-treat principle, which includes all randomised participants.
