An 11-point (0-10) scale for measuring the degree of lethality of suicide attempts is presented. The scale has 9 example “anchors” & uses the relative lethality of an extensive table of drugs. Psychometric studies show the scale to be of at least equal-interval, possibly even ratio measurement level. Having a standerized, commonly used reference scale should greatly facilitate our research & clinical efforts to communicate our findings. The scale can be used reliably by nonmedical personnel.
