The benefits of training and technical assistance (TTA) have been well documented. There is limited literature that explores how complex systems of TTA are implemented and evaluated particularly in the violence prevention field. The Violence Prevention Practice and Translation Branch (VPPTB) within the Centers for Disease Control and Prevention's (CDC) Division of Violence Prevention funds multiple technical assistance providers who are tasked with building the capacity of program recipients to implement comprehensive approaches to prevent multiple forms of violence. VPPTB designed the Violence Prevention Technical Assistance Center (VPTAC) with the goal of implementing and evaluating comprehensive TTA efforts that integrates the work of multiple TTA providers to build the capacity of recipients to plan, implement, and evaluate violence prevention efforts. The VPTAC evaluation incorporates data from program recipients, TTA providers, and TTA modalities enabling the VPPTB staff to show improvement in technical knowledge, gather examples of enhanced implementation, and facilitate proactive TTA planning. An important step in the process of evaluating VPTAC from a system-level perspective required an expansion beyond evaluating a single TTA event, provider, or engagement. This is essential to understand how a diverse set of TTA activities and partners work together in their efforts to build capacity.

INTRODUCTION: In 2020, suicide was the 12th leading cause of death among adults in the U.S. Previous research has shown that one common precipitating circumstance among adult suicide decedents is experiencing intimate partner problems (IPPs), such as divorce, separation, romantic break-ups, arguments, conflicts, and intimate partner violence. This study examines how precipitating factors differ between IPP- and non-IPP-related suicides. METHODS: In 2022, this study analyzed National Violent Death Reporting System data from adult suicide decedents in 48 states and 2 territories between 2003 and 2020. Multivariable logistic regression models were used to compare precipitating circumstances between IPP- and non-IPP-related suicides, controlling for sociodemographic characteristics. RESULTS: Of the 402,391 suicides, 20% (n=80,717) were known to be IPP-related. Circumstances that significantly increased the odds of IPP-related suicides included a history of suicidal thoughts and attempts and mental health problems (depressed mood, alcohol problem, mental health diagnosis), life stressors (interpersonal violence perpetration and victimization, arguments, financial problems, job problems, family problems), and recent legal problems. Non-IPP-related suicides were more likely to occur among older individuals and to be precipitated by a physical health problem or crime. CONCLUSIONS: The findings can inform prevention strategies that build resiliency and problem-solving skills, strengthen economic support, and identify and assist people at risk for IPP-related suicides. The Centers for Disease Control and Prevention's Suicide Resource for Action and Intimate Partner Violence Prevention resource packages highlight the best available evidence for policies, programs, and practices related to preventing suicides and IPP.
