Study type
Interventional
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, education PDF, hypothetical scenario of someone presenting with suicide risk, an open question asking how they would respond, Bystander Intervention Model Performance Scale (BIMPS), Manipulation Check Questions asking how much the education information aligned with the BIM, debrief page. The total questionnaire takes approx. 30 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 and asking a 5 point scale question: 'I read the factsheet carefully and in full' - 'strong disagree, disagree, neutral, agree, strongly agree'.
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.
Participants are asked to provide a typed response of how they would respond to a hypothetical scenario of suicide risk after reading the sheet. Their response is then compared to a checklist of behaviours based on best practice guidelines. The total number of appropriate responses are then totalled and entered into SPSS as a total score on the 'Risk Assessment Ability Checklist' and 'Protective Action Ability Checklist' and differences between groups compared.

Comparator / control treatment
This group will receive suicide prevention education material which is NOT BIM-informed and based on currently available information and delivered as above.
This sheet is compiled from readily available resources for the public from RUOK? and Sane: https://irp-cdn.multiscreensite.com/22b3e3c9/files/uploaded/RUOK_MobileTipSheet_HowToAsk_265x470_V1%5B2%5D.pdf

Outcomes
Primary outcome [1] 306860 0
Mean suicide risk assessment ability score.
This score is derived from a checklist of evidence-based, best practice guidelines in suicide risk assessments. Participants' qualitative responses through an 'action plan' is manually compared to this checklist and rated 0 (not mentioned), 1 (mentioned in little detail) or 2 (mentioned in great detail) on each factor including for example asking about suicide ideation, asking about suicide plan, asking about mental health history, asking about social support. Each participants score on this checklist is then totalled and entered into SPSS to compare the mean scores between the experimental and control group.
Timepoint [1] 306860 0
Post intervention only - immediately after.
Primary outcome [2] 306861 0
Mean suicide risk protective action ability score.
This score is derived from a checklist of evidence-based, best practice guidelines in keeping a person at risk of suicide safe. Participants' qualitative responses through an 'action plan' is manually compared to this checklist and rated 0 (not mentioned), 1 (mentioned in little detail) or 2 (mentioned in great detail) on each factor including for example taking the person to see a Psychologist or taking them to hospital for further assessment and providing ongoing support. Each participants score on this checklist is then totalled and entered into SPSS to compare the mean scores between the experimental and control group.
Timepoint [2] 306861 0
Post intervention only - immediately after.
Secondary outcome [1] 349964 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 - the 'Bystander intervention in bullying and sexual harassment' Scale (Nickerson et al., 2014). The adapted measure has been validated by the author in a previous study with 281 participants were good internal consistency and congruent validity was found.

Efficacy
Statistical methods / analysis
Both qualitative and quantitative data will be collected. According to Francis et al. (2010), to reach saturation of ideas in qualitative data, approximately 12-17 participants per group are required. According to Cohen (1992), for quantitative data, to detect a moderate effect size between two independent sample means at an alpha level of .05, with power at .80, the study will require at least 64 participants in total. Qualtrics will record the length of time participants spent on reading the experimental factsheet. If participants’ time is 30+ seconds less than the average time it takes for pilot participants, their full response will be excluded from analysis. Further, Factor Analysis will be conducted on the BIMP measure below which will require at least 200 participants. To meet all of the aforementioned requirements, the study aims to recruit at least 250 participants.

PURPOSE:
To compare the efficacy of Bystander Intervention Model-informed suicide prevention material with standard existing material in promoting appropriate suicide risk assessment and protective action in the general community according to best-practice to suicide prevention.

HYPOTHESES:
1. The experimental condition will have a significantly higher suicide risk assessment ability score than the standard condition.
2. The experimental condition will have a significantly higher suicide protective action ability score than the standard condition.
