About SPTD

The SPTD is a publicly available 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 utilizes systematic review methods to search for, identify, and compile data from relevant trials. Researchers abstract detailed data elements related to participant, intervention, comparator, outcome, and other study characteristics, and conduct risk of bias assessments. The search is updated approximately twice yearly to maintain an up-to-date database. Data are currently available in Excel spreadsheets.  There are two Excel spreadsheets that compromise the SPTD. One contains all randomized controlled trials (RCTs) and one contains all other study types, non-RCTs.
