The privilege and responsibility of suicide prevention.

Each year about a million people worldwide take their lives, and a further unknown number, but probably no less than 20 million, attempt suicide. In addition, for every person who engages in suicidal behavior, another five or six will be associated with them in some way, making a conservative total of 100 million people worldwide who are affected each year--and to whom we have some degree of responsibility. There is no one approach to suicide prevention, and probably more so than for any other human condition, we are privileged to be able to collaborate with many different disciplines in our endeavors. However, there is a considerable responsibility to ensure that whatever our own area of expertise and interest may be, we should apply universal principals of objective analysis to these diverse contributions. This is addressed by examining research from four broad areas. First, there are studies that irrevocably bring together the sociological and biological approaches to suicide. Second, there are reports that support the notion of the universality of suicide. Third, despite considerable attention paid to the media, its influence on suicide is very limited. And finally, although there have been pessimistic reviews, there are persuasive data from innovative research designs that have documented that we can prevent suicide.
