There are no national data that document the link between intimate partner violence (IPV) and firearm suicide. This dissertation will use the National Violent Death Reporting System (NVDRS) and apply supervised machine learning to assess the proportion of firearm and non-firearm suicides that are precipitated by IPV in the United States.

We will create a new IPV variable specifically for suicides in NVDRS that can be used for future firearm policy research. By improving available data about the contribution of IPV to suicide, this dissertation may reveal new program and policy opportunities for prevention.
This project will examine over n=123,000 suicides in NVDRS (2013-18), representing data from 38 states, Washington DC, and Puerto Rico. Using text from NVDRS death narratives, we will apply Natural Language Processing (NLP) to develop an algorithm that can accurately classify suicides as IPV-related or not. This project will leverage nearly 8,000 cases that have already been hand-reviewed during pilot studies as our ‘gold standard’ for classification. After developing and deploying the algorithm, we will then explore the relative contribution of IPV to firearm and non-firearm suicide.
This will be the first study to enumerate the contribution of IPV to suicide outcomes using national data. This dissertation may catalyze improvements in death investigation and NVDRS data abstraction processes while also helping inform policy decisions to holistically prevent firearm violence.
