Most individuals who go on to die by suicide (decedents), have seen their primary care provider (PCP) within 12 months of suicide or 80%; compared to 31% of decedents who have seen their behavioral health (BH) provider within 12 months of death. Using a health program evaluation, from a public health standpoint, evaluate real-time suicide surveillance data in contrast to when an evidence-based suicide intervention is implemented, as part of a larger study. This study seeks to evaluate unit-level suicide-related serious incident reports (SR-SIRs), within (pre-intervention) 12 months of the evidence-based practice (EBP) training provided by subject matter experts (SMEs) to PCPs and BH providers. Then, evaluate (post-intervention) the effectiveness of the EBP training using SR-SIRs and measurements. This pre/post study design can be replicated across the Army. We will seek to recruit Command teams; PCPs and BH providers currently credentialed across the garrison and local MTF using our professional network (convenience and snowball sampling). Those PCPs and BH providers who do not participate (our matched control group) in the study that belong to the same unit to participants recruited will be compared via SR-SIRs. Measurements: these will include unit SR-SIRs in the 12-months leading up to the intervention; and 12-months post-intervention, i.e., intervention #1: introduction class; and intervention #2: crisis response planning (CRP) training. Study measurements will be administered to Command teams, PCPs, and BH providers who participate in the study, i.e., theory-driven measurements (INQ-15, PAS, MSAQ) will be tailored to these active bystanders. For PCPs and BH providers only, an adapted version of the 2011 Graham and colleagues’ 14-item measurement will be administered at the time of the intervention (baseline), 3-, 6-, 9- and 12-month timepoints. This measurement was previously used by the first author’s 2025 doctoral dissertation study and found higher Cronbach’s alpha scores for composite scales were on average, higher than the original 2011 measurement, removing problematic words based on existing literature and tailored for military providers. REDCap, a secure web-based platform, will be used to administer and store surveys. Intervention #1: Command teams, PCPs, and BH providers will all attend the introductory and study overview class, will be shown the data on suicidal thoughts and behaviors (STBs) look like across military and civilian populations. How the US Army, when age- and demographically-adjusted is more at-risk for STBs compared to other branches and civilians. Next, we will then walk participants through suicide prevention and intervention strategies are proven to be effective. How the literature shows that providers who rely on depression-based screeners for screening patients’ suicidality are less likely to accurately detect suicidality versus asking direct questions about a patient’s suicidality (suicide-risk screeners); and directly addressing suicidality via EBPs specifically targeting suicidality are effective compared to other practices. Command teams will be excused ahead of intervention #2 taught by SMEs, in-person: CRP, a one-day training that both PCPs and BH providers can receive, while also receiving continuing education units (CEs). We will then use descriptive statistics, bivariate analysis, regression models to analyze our study data.
