Motivational Enhancement Therapy (MET) is a systematic intervention approach for evoking change. It is based on principles of motivational psychology, and is designed to produce rapid, internally-motivated change. This treatment approach does not attempt to guide and train the client, step by step, through recovery, but instead employs motivational strategies to mobilize the client's own change resources.  

Motivational interviewing is non-judgmental, non-confrontational and non-adversarial. The approach attempts to increase the client's awareness of the potential problems caused, consequences experienced, and risks faced as a result of the behavior in question. Alternately, therapists help clients envisage a better future, and become increasingly motivated to achieve it. Either way, the strategy seeks to help clients think differently about their behavior and ultimately to consider what might be gained through change.
