Contemplation Ladder

The Contemplation Ladder was designed as a continuous measure of readiness to quit smoking. It is a very brief measure, sensitive to interventions designed to enhance motivation in substance abusers. It consists of the image of a ladder with 11 "rungs" and 5 anchor statements loosely reflecting the stages of change (precontemplation, contemplation, preparation, action, maintenance). Subjects circle the "rung" that most closely matches their level of interest in changing their smoking behavior.
