Many people with depression have suicidal ideas, and asking about these is a crucial aspect of their assessment. They often find it a relief to talk about these ideas. Asking about suicidal ideas is a sequential process, beginning with questions about the severity of the low mood. Then ask if the patient has ever felt that life is not worth living. A 'yes' could be followed by enquiring whether the patient has ever felt like ending their own life. Finally assess if the patient has any particular plans in mind.
