In the past 20 years, there has been a sea change in the treatment for addiction, with the emphasis shifting from confrontation toward enhancing motivation for change and building the skills to effect those changes. Carrying out these two aspects of treatment, however, is easier said than done. Enhancing motivation is difficult in part because motivation can be evanescent; being motivated is a state, much like -hunger or satiety, not a trait. A person can be hungry at noon but not be a "hungry person" because eating lunch will make the -person full. Similarly, someone can be "motivated" to stop drinking, pass by a bar, experience a powerful urge to drink, and yield to the urge. Does that make the person "unmotivated?" It's -complicated, yet clinicians often refer to patients' level of -motivation when referring to them, as if it were static.
