Before people shout, Awareness. is there any evidence it helps?
I think it's obvious that this question is not unique to our community but applies to anyone. So, I've been doing some Googling trying to find actual research papers.
This study done on suicide prevention programs in the Air Force
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC292986/ :
"A 33% relative risk reduction was observed for suicide after the intervention; reductions for other outcomes ranged from 18-54%"
Another study, found no tangible benefit
https://pubmed.ncbi.nlm.nih.gov/19723735/But the most comprehensive paper seems to be here
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3492539/ it mentions a 4 part program, that when implemented has seen good results.
(1) Training of general practitioners and support through different methods; (2) A public relations campaign informing about depression, (3) Cooperation with community facilitators (teachers, priests, local media, etc.), and (4) Support for self-help activities as well as for high-risk groups.
One interesting note on this topic, also from that paper:
"Of note, media reports covering specific suicide methods were found to increase suicidal behaviors in the community in some studies (73, 74). Therefore, it is advisable to avoid inclusion of specific details such as the location or method of death in news reports."
I think the bottom line is that there is a lot we can do without spreading stories and rumors about what did or didn't happen in one-off cases.
