This study plans to learn more about the use of one of two self-guided online cognitive behavioral therapy courses. One is focused on symptoms of depression and one is focused on history of suicidal thoughts and behaviors.

Based on previous work with other computerized CBT (cCBT) interventions (e.g., cCBT-D), which has found that cCBT has similar effectiveness to traditional CBT, members of the team along with Veterans Health Administration (VHA) leaders have developed computerized cCBT-SP and cCBT-D courses that will be ready for safety, feasibility, and acceptability testing. If proven to be feasible, safe, and effective, these courses could be made available to all Veterans, at no cost to users.
