Intervention description
The 8-week intervention will comprise 24 pieces of content; three per week. The intervention group will receive the #chatsafe suicide prevention content. Participants will receive their content via text message once per week, with links to the weekly content hosted on Instagram. Because of the rolling recruitment used in the trial, all of the trial content is already on the trial Instagram page so appropriate links can be sent to participants as they move through the trial.
The campaign content educates participants across four core areas: a) talking safely about suicide online; b) sharing your own thoughts, feelings or experiences with suicide safely online; c) responding to someone who may be suicidal; and d) communicating safely about someone has died by suicide.
Content is in the form of 3 Instagram posts per week (sent together on one occasion), with posts having between 1-8 'tiles' with the caption containing further information for each topic. Throughout the campaign, different mediums are used including still image, video, digital art, animation, block text and mobile phone screen recordings. For example, the week 3, post 3 content uses a series of images describing how to create content warnings. The post has 4 tiles, that describe why content warnings are used, how to create a content warning, and support services that can be included in content warnings. The caption gives further context to the post.
Once per week, the text message will be sent containing a link to the content. Halfway through each survey period, a follow-up engagement text message will be sent either reminding participants to complete their survey or checking in and offering assistance with participation.
The trial content was co-designed with young people. First, the entire #chatsafe program of work has been conceptualised, designed, and conducted in partnership with young people. The guidelines themselves (that the trial content is based off) were created using the Delphi consensus method, with young people as an expert panel. The first #chatsafe social media campaign was co-created in partnership with over 140 young people, across a series of workshops each containing up to 20 young people. For the trial content specifically, two youth workshops (N = 26) were conducted to assist with the initial planning of the trial in April 2021. The study was then presented to the Orygen Youth Research Council (YRC) in November 2021 and feedback on intervention development and study conduct was obtained from 8 young people. Next, three co-design workshops were conducted in April and May 2022 (N = 46) to help create the trial content. These workshops were facilitated by creative agency Portable, who created the final Instagram posts that will be used.

Control condition
The 8-week intervention will comprise 24 pieces of content; three per week. The control group will receive the PROSPEct social media content. The PROSPEct campaign content comprises still visual posts with anywhere between 1 and 3 tiles. Once per week, a text message will be sent containing a link to the content. Halfway through each survey period, a follow-up engagement text message will be sent either reminding participants to complete their survey or checking in and offering assistance with participation. Because of the rolling recruitment used in the trial, all of the trial content is already on the trial Instagram page so appropriate links can be sent to participants as they move through the trial.
The campaign educates young participants across 4 core areas: a) Understanding our bodies and the relationships with ourselves (e.g. pleasure & diversity); b) exploring the relationships we have with others e.g. consent, sexual activity, healthy relationships; c) staying safe online and in person e.g. online dating, STI awareness, contraceptive methods and d) owning our sexual wellbeing e.g. being self-aware and finding support services
The tiles include still image, digital art and block text to convey campaign messaging. Content is in the form of 3 Instagram posts per week, with posts having between 1-3 'tiles' with the caption containing further information for each topic. For example, the week 3, post 1 content outlines and describes the importance of sexual consent. The post and has 3 tiles, and together with the caption, it describes what consent is, discusses legal consent in the context of different states and territories in Australia, and the impact of intoxication on one’s capacity to consent to sex.
The control campaign content was drafted by the researchers, based on the learnings from the PROSPEct project (ACTRN12622000679785), which aimed to develop an intervention to promote sexual wellbeing in young people with mental ill-health before testing it in a clinical trial. These learnings came from collaboration from 29 key stakeholders including 8 young people with mental ill-health, 3 carers and 18 clinicians who provide mental health or sexual health support to young people with mental ill-health. A working group was convened with 4 young people, who were service users themselves and advocates for youth mental health to provide feedback on the first draft of the intervention. There was further feedback from 9 key stakeholders including 2 young people, one carer and six clinicians after making these changes. Consultation was sought from colleagues who undertook other projects to inform the development of LGBTQIA+ inclusive and gender affirming care training.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is concealed as the randomisation schedule is computer generated by independent Information Technology (IT) personnel with guidance from the study statistician. The schedule will then be implemented by a member of the study team (other than the statistician) into the REDCap database management software for allocating treatments to individual participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Block randomisation with varying block sizes with an allocation ratio of 1:1 will be used.

Statistical methods / analysis
At baseline, state of residence, postcode, age, Aboriginal and/or Torres Strait Island status, gender identity, sexual orientation, primary language spoken at home, cultural background, educational and occupational background will be reported using descriptive statistics and will be checked for imbalance between trial arms. The moderating effect of gender (male, female, trans and gender diverse), age group (i.e., 16-20 and 21-25), time spent on social media, psychological distress, and previous experience of suicide and self-harm will be considered in analyses as covariates.

Analyses will be done on an intention-to-treat basis, where all individuals randomised will be included in the analysis by their allocated trial arm status regardless of whether they received all, part or none of the intended treatments. For the primary analysis, we will use linear regression to estimate the difference in the mean changes between the intervention and control arms at T2 in the outcome safety when communicating online about suicide, as measured via the #chatsafe Online Safety Questionnaire. This analysis will adjust for T1 scores. Multiple imputation will be used to address attrition bias, with 50 imputation samples generated using chained equations. We will conduct two sensitivity analyses. One sensitivity analysis will be undertaken using complete cases only (i.e., repeating the primary analysis but only analysing participants who have complete T1 and T2 data). The second sensitivity analysis will use multiple imputation and include the following potential moderating factors as covariates: gender (male, female, trans and gender diverse), age group (i.e., 16-20 and 21-25), time spent on social media, psychological distress, and previous experience of suicide and self-harm.

Our secondary outcomes at T2 and T3 will be analysed on the same basis as our primary analysis and the two sensitivity analyses. We will use linear regression for continuous outcomes, logistic regression for binary outcomes and negative binomial regression for counts.

Potential iatrogenic effects will be analysed on a weekly basis and will serve as an interim analysis throughout the course of the study. If the weekly content is assessed as ‘very distressing’ by more than 20% of participants per week the Safety Monitoring Committee (SMC) will be consulted, and the content may be withdrawn. The acceptability of each week’s content will be analysed and reported as descriptive statistics (frequencies and percentages).
