What is a common technique to gauge a client's level of suicidal ideation?

Asking about a client's thoughts of self-harm is a common and direct technique used to gauge their level of suicidal ideation. This approach allows the counselor to gather crucial information about the client’s current mental state, including any existing feelings of hopelessness, plans for self-harm, or previous attempts. It creates a safe space for clients to express their feelings and thoughts about suicide, making it a critical part of assessing risk and determining the need for immediate intervention or support.

In contrast, encouraging the client to write a journal may help in processing their emotions but does not directly address suicidal thoughts or behaviors. Inquiring about their support network can be valuable in understanding the client's outside resources and coping mechanisms but does not specifically illuminate their thoughts on self-harm or suicide. Discussing past experiences with therapy can provide insights into the client's history and willingness to seek help, yet it does not specifically assess current suicidal ideation. Hence, the most effective method among these for measuring suicidal thoughts is directly asking about them through the lens of self-harm.
