^aP4 is a mnemonic for the 4 screening questions: past suicide attempt, suicide plan, probability of completing suicide, and preventive factors. ©Copyright 2010 Kurt Kroenke, MD.

^bAny individual who responds “yes” to a question about thoughts of self-harm is asked 4 additional questions—the 4 P’s on past history, plan, probability, and preventive factors. Shaded responses are those that are more concerning for suicidal ideation.
