Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Schools Education Program (SEP) educational intervention aims to educate students on healthy sexual relationships and prevent sexual violence by enhancing student knowledge, attitudes and behavioural intentions.

Year 9 students in the intervention arm will receive three in-person 90-minute sessions of SEP across a seven-week period. The sessions will be delivered by trained facilitators from Laurel House, in partnership with the Tasmanian Women’s Legal Service. The sessions will be delivered during class time with two-week intervals between sessions.

Session One:
In the first session, facilitators will use small-group activities and open discussion to explore the following topics: 1) healthy relationships, including communication, boundaries, mutual respect and consent, 2) defining sexual violence, common misconceptions about sexual violence, and recognising its impact on victim-survivors, 3) gender equality and harmful stereotypes, law changes over time that have affected women’s roles, gendered societal expectations, and how these influence perceptions of sexual violence.

Session Two:
This session delves into legal aspects of consent and emerging forms of sexual violence. With expert insights from a women’s legal service lawyer, the session will explore: 1) legal definitions of consent, 2) image-based abuse, 3) non-fatal strangulation (sexual choking), stealthing and the law, 4) and guidance on accessing legal support and counselling.

Session Three:
The final session for students will focus on navigating consent, digital safety, and active bystander strategies. Using discussion and small-group scenarios, facilitators will focus on 1) building skills for clear, respectful dialogue about boundaries and mutual agreement in relationships, 2) how pornography shapes perceptions of sex, relationships, and unrealistic expectations. 3) reinforcing the serious legal consequences of accessing, sharing, or producing Child Sexual Abuse Material, and its lifelong harms to victim-survivors. 4) early warning signs and strategies to address harmful sexual behaviours, and 5) practical bystander strategies to safely challenge harmful behaviours, support potential victims, and disrupt unsafe situations.

In addition to educational sessions, there will be ‘School Student Champions’ (SSC) recruited at each school to help accelerate the diffusion of messages in the school population. Key points about the SSCs:
- Expressions of interest will be invited from students at each school to become SSCs – up to 7 SSCs per school
- Laurel House will consult with SSCs regarding any specific issues or concerns at the school
-SSCs will be given leaflets and posters of support services to display in areas of the school
-Laurel House will check-in with SSCs between sessions to gain feedback and a sense of how the sessions have been received.

Additionally, members of the school staff and parents/caregivers will be invited to attend a 2-hour educational session on consent and healthy relationships prior to the commencement of the student sessions.

The SEP intervention includes the use of available resources such as The Consent Continuum (Body Safety Australia), the Healthy Relationship Wheel (Reproductive Health National Training Center), Duluth Equality Wheel (Domestic Abuse Intervention Project), Commonwealth Consent Policy Framework (Department of Social Services), and resources adapted from The Line (Our Watch), eSafety Commissioner (Australian Government), and the It’s Time We Talked program designed by Maree Crabbe and David Corlett. Other resources and activities have been developed for SEP by Laurel House, including scenario cards, and a range of interactive, small-group activities focused on gender stereotypes, timeline of laws, identifying trusted people, and communication skills.

Adherence to the intervention will be assessed using fidelity sheets completed by facilitators delivering the sessions.

Year 9 students in the control arm will not receive the program and will instead receive their usual school curriculum.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Schools (clusters) will be randomised using a remote system set up by the LTU Statistics Platform. The allocation sequence will be stored on a secure server and concealed from all personnel involved in the trial. It will be created, using computer-generated random numbers, by a statistician with no link to, or contact with, any of the participating schools.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Using computer-generated random numbers, randomisation will be stratified by the following five variables:
1) Year 9 student population (size)
2) Region of Tasmania
3) Index of Relative Socio-Economic Disadvantage, by suburb and locality (IRSD)
4) Indigenous enrolment, percentage
5) Index of Community, Socio-Educational Advantage (ICSEA)

Efficacy
Statistical methods / analysis
The study results will be reported using the CONSORT guidelines for cluster RCTs. The proportion of students completing baseline, immediate-post and six-month follow-up surveys will be reported. A descriptive analysis will be used to summarise and describe the baseline characteristics (categorical or continuous variables) of the student participants, such as age, gender, sexual orientation, Indigeneity, country of birth, language spoken at home, and autism, ADHD or learning disabilities. For the quantitative outcome measures, a comparison of the intervention and control will be undertaken using SPSS or STATA to determine whether the Group 1 (treatment) mean (µ1) is greater than the Group 2 (control) mean (µ2) (H0: d = 0 versus H1: d > 0, d = µ1 - µ2) on the primary outcome of knowledge. This will be repeated for secondary outcomes e.g. attitudes and behavioural intentions. Mean differences on outcomes will be assessed across trial arm and between baseline and post, baseline and follow up and post and follow up. The comparison will be made using a one-sided t-test (alpha 0.025) with the degrees of freedom based on the total number of subjects. Estimates for differences between intervention and control (odds ratios and least squares mean differences) will be adjusted for clustering (students nested within schools) and presented alongside 95% CIs. Intention to treat analysis will be completed and any missing data will be reported and managed using listwise deletion.
