Researchers from the Universities of Bristol, Oxford and Manchester found that nearly half of websites showing up in queries of the four top search engines gave "how to" advice on taking one's own life.
Only 13 percent, by contrast, focused on suicide prevention or offered support, while another 12 percent actively discouraged suicide.
Previous studies have shown that media reporting of suicide and its portrayal on television influence suicidal behaviour, particularly the choice of method used, but little is known about the impact of the Internet.
How the study was done
The study, published in the British Medical Journal, replicated a typical search that might be undertaken by a person looking for instructions and information about methods of suicide. The same set of search terms were fed into Google, Yahoo, MSN, and Ask.
The researchers then analysed the first ten sites from each search, giving a total of 480 hits. Just under half of the sites provided some information about methods of suicide, while almost a fifth were for dedicated suicide sites, half of them actively encouraging, promoting, or facilitating the taking of one's life.
Overall, Google and Yahoo retrieved the highest number of dedicated suicide sites, whereas MSN had the highest number of prevention or support sites and academic or policy sites.
In addition, the three most frequently occurring sites were all pro-suicide, while the information site Wikipedia was fourth. "How to" sites are not illegal in most countries, and are not often caught by search engine filters. – (Sapa)
