Suicide is one of the leading causes of death in the United States. Statistics from the Centers for Disease Control indicate that rural suicide rates are higher than urban rates. In the United States, the states with larger areas of rural populations consistently reach the highest suicide rates in the nation, with Montana often at the top: 28.9 per 100,000 people in 2017. Factors specific to rural environments may both increase the likelihood that suicide attempts will be fatal and they can also limit the effectiveness of suicide-prevention initiatives that may work in urban settings. Considerations include geographical isolation, isolated work, social isolation, limited availability of mental health services, stigma associated with seeking care from mental-health professionals, availability of firearms and poisons, and limited security for firearms (gun locks, secure storage).
In response to the high rural suicide rates, state governments have been investing in data collection to identify the reasons for suicide attempts and fatalities, aiming to formulate optimally effective policies and ultimately to save lives. The STARS project at CMAC re-analyzes deidentified data on suicides from the state of Montana using statistical, geographic, machine-learning, and computer-simulation techniques to investigate existing interpretations of causal factors and ultimately to generate cost-benefit analyses of possible policy interventions. Based on a thorough review of literature and consultation with subject-matter experts, we are building a computer simulation to test the efficacy of a range of strategic interventions and policy proposals, with the goal of advising policy professionals and change agents with the power to reduce suicides in rural communities. Computational modeling and simulation is a tool ideally suited for handling multiple interacting factors in a complex causal system, which is what we see in the problem of rural suicide. Once validated and tested, this policy simulation will be readily generalizable to other settings and other countries.
The STARS project aims to build a computational model, incorporating psychological autopsy data along with the insights and expertise of local service providers and policy professionals to improve suicide prevention efforts, particularly in rural settings. These models have the potential to generate insights into policy proposals and to spur the generation of new policy ideas, thereby assisting policy professionals and service providers to craft more effective solutions, ultimately mitigating a severe public health problem and saving lives.
