Recently, the Suicide Prevention and Response Independent Review Committee (SPRIRC) released a report detailing a number of recommendations to reduce suicide risk across the Services. One focus of their recommendations is the need to provide training to behavioral health providers in the Military Health System, both direct care providers and those in the TRICARE network. The Committee rated disseminating training in evidence-based suicide prevention treatments as a “high” priority, identifying it as a “‘necessary’ or ‘must’ change” requiring the highest level of attention and resources from the Department of Defense (DoD). The SPRIRC also recommended the development and provision of similar suicide prevention training for behavioral health technicians and primary care providers. The timeline and level of effort required to train the thousands of identified providers and technicians would make in-person training events unrealistic and infeasible. As an alternative to meet these training goals, online training provides a solution that decreases the logistical challenges including travel needs and schedule disruptions for both the trainers and learners and can be delivered at a lower cost with increased scheduling flexibility. Prior work supports the use of online dissemination of evidence-based psychotherapies (EBPs) with some studies finding no difference in the effectiveness of online and in-person training and others finding greater benefits when the training was delivered online. However, results are varied as to whether online learners are similarly satisfied with the training received as learners who attend in-person workshops. Data suggest some of this variability in findings may be related to the specific type of EBP being disseminated. Importantly, there is very little work comparing the acceptability and effectiveness of online and in-person training for the dissemination of suicide prevention EBPs. Given the pressing need to expand training initiatives identified in the SPRIRC, and the logistical difficulties of large-scale, in-person training efforts, the current project aims to assess the effectiveness of online trainings for suicide prevention. Program evaluation data were collected for all 2-day cognitive behavioral therapy for suicide prevention (CBT-SP) workshops conducted by the Center for Deployment Psychology online or in-person between Fiscal Years 2019 and 2023. Prior to transitioning all workshops online in response to the COVID-19 pandemic, learners self-selected into in-person or online workshops. Standard program evaluation data collected from CBT-SP workshops included an assessment of participant knowledge about the protocol, readiness to implement the protocol, satisfaction with the training, and, for a subset of learners, a self-evaluation of clinical skills taught during the workshop. Learners in CBT-SP workshops consistently demonstrated increases in knowledge, readiness, and skills related to the training material. The effectiveness of in-person and online dissemination of CBT-SP will be compared upon final data collection for workshops completed in September 2023, which will conclude in October 2023. Implications of the findings for the upcoming large-scale dissemination of suicide prevention trainings in response to the 2023 SPRIRC via online platforms will be discussed.
