This resource introduces the Readiness Ruler, a practical Motivational Interviewing tool designed to assess a patient’s importance, confidence, and readiness regarding behavioral change. Developed for use within forensic and mandated treatment settings, it encourages non-judgmental dialogue that explores a patient’s internal motivations and ambivalence rather than focusing on compliance. By asking strategic follow-up questions staff can effectively elicit change talk and identify actionable next steps that align with the individual’s own goals and autonomy.
