Motivational interviewing (MI) is similar to motivational therapy in the sense that it attempts not to create change within an individual but give foundation and support to the change the individual finds within him or her self. As a treatment for individuals with all types of substance abuse disorders, motivational interview therapists focus on trying to erase any type of ambivalence the individual may have towards their abuse. Similar to MET, motivational interviewing finds 'change talk' very important and the clinician interacts with the patient through open-ended questions, affirmations, reflections and end-of-session summaries. There are three key elements that build the foundation of motivational interviewing; collaboration, evocation and autonomy. Evocation is expressed through the clinician's responsibility to "draw out" the opinions and commitment to change of the client, rather than suggesting or imposing ideas.
