This review summarizes the current status of suicide assessment and focuses on suicide specific instrumentation and methodologies developed in the last 30 years. The purpose is to provide a brief overview and comparison of modern suicide assessment tools. The emphasis is on instruments and methodologies that may have utility beyond the individual clinical application. Thirty-two suicide rating scales, as well as case vignettes, psychological autopsies, suicide reviews, and postsuicide assessment instruments are described. The Scale for Suicide Ideation-Worst and the military’s postsuicide assessment instruments appear to have the greatest reliability, broadest application, and utility for large-scale intervention/prevention purposes.
