Brief Skills for Safer Living (Brief-SfSL)

The goal of this project is to assess the efficacy of Brief-Skills for Safer Living (Brief-SfSL) in a randomized control trial. The investigators will be testing 150 participants Canada-wide, half of which will be randomized to receive Brief-SfSL (B-TAU) and the other half will be randomized to receive Brief-SfSL after a 3 month waitlist (WL-TAU). The main questions this study seeks to answer are: * Is B-TAU more efficacious than WL-TAU for reducing suicidal thoughts at 3 months? * Is B-TAU more efficacious than WL-TAU at 3 months for reducing depression severity, anxiety, and anhedonia? * Is B-TAU more efficacious than WL-TAU at 3 months for improving social connectedness, emotional regulation, functioning (work, life, social), executive control and social problem-solving? * Are adverse events equivalent between B-TAU and WL-TAU at 3 months?
