We will conduct a randomized
A total of 120 18-24 year olds will be recruited from the community and randomly allocated to view (a) suicide prevention Public Service Announcement or (b) a control PSA on an unrelated health

The suicide prevention PSA is a 30 second ad. The ad has been specifically designed for the project by young people. It features young people and it is about reaching to help a friend or peer who might be experiencing suicidal thought. It has never been viewed before.

Young people will not be able to proceed to completing the questionnaires if the video is not watched twice. This is monitored via the electronic data base .

At Time 1 (pre-viewing), participant will complete a series of outcome measures, At Time 2 (immediately post-viewing), participants will complete a questionnaire about the PSA itself and a measure of distress. At Time 3 (four weeks post-viewing), participants will re complete previously completed outcome measures.

Data will be analysed on an intention-to-treat basis using standard techniques for longitudinal data analysis. We will analyse changes in each outcome measure by treatment group and time.

Changes in the willingness to intervene (as measured by the Willingness to Intervene (WIQ) Questionnaire) will be used as the primary outcome measure. A linear regression analyses using scores on the WIQ as the primary outcome of interest with the key predictor being the treatment group participants were randomised to. The analysis will also include a range of socio-demographic, clinical and treatment variables as covariates.

Summary
Brief summary
Youth suicide is a major public health problem in Australia and worldwide. This study aims to build the evidence base for an effective public education campaign for young people. In particular we are testing to see if a 30 second ad can lead to reaching out and helping a peer at risk of suicide.120 young people will be recruited from the general population randomly allocated to view one of two PSA. The intervention PSA is about helping someone at risk of suicide and the control PSA is about the impact of sugary drinks. Participants will answer questions pre-viewing, post-viewing and four weeks later to permit an examination of several positive and negative outcomes.
