A provider uses the confidence ruler with a client during a session. They ask, $"$On a scale from $0-10,$ where $0$ is not at all important and $10$ is extremely important, where would you place the importance of changing your alcohol use?" After the client responds with $"4,"$ the provider should follow up with which key question?

"What could get you one number higher?"

"Why do you think you're at a $4?"$

"How come you are at a $4$ and not a zero?"

"How long have you been at a $4?"$
