About SPTD

The mission of the SPTD is to establish a publicly available and up-to-date database of study-level data from published trials of suicide prevention approaches. The database may be used for future systematic reviews or clinical practice guidelines, for identifying research gaps, and as an information resource for clinicians, patients, policymakers, and family members.

Similar to other clinical trial databases such as the PTSD-Repository, the SPTD will utilize systematic review methods to search for, identify, and compile data from relevant studies. Researchers will abstract detailed data elements related to participant, intervention, comparator, outcome, and other study characteristics, and conduct risk of bias assessments. The search will be updated quarterly to maintain an up-to-date database. In early stages of the project, data will be made available in Excel spreadsheets. In later stages, a website may be developed allowing stakeholders to query the database to address specific questions. 



This project is funded by a service directed research award to Dr. Denneson and Dr. O’Neil from VA Clinical Science Research and Development (CSR&D) (Award # SDR-SPTD-20S).
