Counting suicides and making suicide count as a public health problem

Relatively few countries credibly count their dead (Mathers, Fat, Inoue, Rao, & Lopez, 2005). Thus, differential sophistication as well as sociopolitical and economic support of healthcare and systems to  investigate deaths inevitably leave a large gulf between richer and poorer countries in accurately registering manner and cause of death. And when suicide is in question, […]

Australia revises its mortality data on suicide

The accuracy of suicide statistics is far from being just an obsession for epidemiologists: It directly influences policy-making in mental and public health, planning and funding of preventative strategies,  and research reports. Community awareness and support services depend on reliable reporting, and determining the extent and costs of suicide is important for combating stigma and […]

A study of the Irish system of recording suicide deaths

Background: Many studies have examined the reliability of national suicide statistics. Aims: To examine the Irish system of certifying suicide deaths and data collected by it. Methods: Data were recorded from a police form (Form 104) completed and sent to the Irish Central Statistics Office (CSO) after all inquested deaths that occurred in Ireland in 2002. Results: Of the […]

The gender suicide gap and differential misclassification: A research autobiography

This essay employs a social constructionist perspective to reassess the gender gap in US suicide rates during the early 21st century. Male rates well exceed female rates. However, suicide is undercounted, and undercounting is nonrandom by gender and method. Female suicides frequently select drug intoxication  and other poisoning, a less forensically overt method than the […]

Genetic differences between suicide deaths and deaths of undetermined intent

Introduction Few, if any, prior studies have considered whether undetermined intent (UDI) deaths and suicide deaths differ with respect to genetic liability for suicidal behavior or psychopathology. Methods The authors used Swedish national registry data to identify suicide deaths (N = 31,835) and UDI deaths (N = 10,623); sociodemographic covariates; and registrations for psychopathology. Family genetic risk scores (FGRS) […]

Discovering the unclassified suicide cases among undetermined drug overdose deaths using machine learning techniques

Objective The Centers for Disease Control and Prevention (CDC) monitor accidental and intentional deaths to answer questions that are critical for the development of effective prevention and resource allocation. CDC’s National Violent Death Reporting System (NVDRS) is a major innovation in surveillance linking individual-level data from multiple sources. However, suicide underreporting is common, particularly from […]

Using natural language processing to improve suicide classification requires consideration of race

Objectives To improve the accuracy of classification of deaths of undetermined intent and to examine racial differences in misclassification. Methods We used natural language processing and statistical text analysis on restricted-access case narratives of suicides, homicides, and undetermined deaths in 37 states collected from the National Violent Death Reporting System (NVDRS) (2017). We fit separate […]
