Description of intervention(s) / exposure
The intervention is Bystander Intervention Model (BIM)-informed suicide prevention education material. This material is a PDF factsheet teaching participants about suicide risk factors, warning signs and protective factors and teaching them how to intervene. This is provided in the online questionnaire of this study. Participants are provided with a link to the online questionnaire in the study advertisement. The questionnaire presents the following information in order: demographics, 'Bystander Intervention Model Performance Scale' (BIMPS), hypothetical scenario of someone presenting with suicide risk, 'Confidence and Intent to Intervene Scale' (CITIS), education PDF, BIMPS time 2, CITIS time 2, Manipulation Check Questions asking how much the education information aligned with the BIM, debrief page. The total questionnaire takes approx. 30-45 min to complete.
As stated, the intervention is only delivered once during the overall questionnaire. Adherence is assessed through timing how long participants spend on reading the page.
This factsheet was designed specifically for this study based on evidence-based, best practice guidelines in suicide risk assessment and intervention.
The factsheet is 8 pages - mostly graphics and bullet points - taking approx 10 min to read.

Outcomes
Primary outcome [1] 306862 0
Mean Bystander Intervention Model Performance Scale Score. This is an adapted measure from a previously validated measure which assessed self-reproted bystander intervention in persons exposed to a scenario involving witnessing bullying or sexual harassment. This measure was adapted to suit a scenario of suicide risk. The adapted measure was assessed for reliability and validity in the current study. With a sample of 281 participants, it was found to have good internal consistency and convergent validity.
Timepoint [1] 306862 0
Immediately Pre-intervention.
Immediately Post-intervention (primary endpoint).
6-month follow-up.
Secondary outcome [1] 349965 0
Mean Confidence and Intent to Intervene Scale Score.
This scale was specifically designed for the currents study to assess participants' level of confidence and intent to intervene in a hypothetical scenario involving suicide risk. It was assessed for reliability and validity in the current study. With a sample of 281 participants, it was found to have good internal consistency and convergent validity.

Statistical methods / analysis
This study required a minimum 64 participants per group to gain sufficient power (optimally .80) and a large effect size (optimally a Cohen’s d of .50) at alpha .05 (Cohen, 1992). As the study involved factor analysis however, the study aimed to recruit at least 300 participants for robust analysis and interpretation. SPSS was used to analysis quantitative data exported from qualtrics.

Summary
Brief summary
PURPOSE:
The aim of the study is to evaluate whether a BIM-guided factsheet about suicide prevention can improve participants’ knowledge, confidence and intent to intervene more than a standard condition when presented with a peer at risk of suicide.
HYPOTHESIS:
A public suicide prevention strategy which addresses the BIM will be more effective at increasing knowledge, confidence and intent to intervene when presented with someone at risk of suicide than a standard condition which does not address the BIM.
