A follow-up study of those who called a suicide prevention center.

Reports concerning the number of suicides among those who have called suicide prevention centers have varied considerably in methods and in results. It is therefore difficult to determine the relevance or effectiveness of such centers. The author points out some of the desiderata for more useful studies and reports the results of his own study in Chicago: out of about 1,300 callers, there were eight suicides, four equivocal deaths, and five "suicides" by alcohol.
