Motivation to Change Substance Use

An eight-item measure tapping motivation to change, self-efficacy, and change intention was assessed using visual analog scales. The average of the eight items was calculated resulting in a score ranging from 1 to 100. The measure was asked at baseline (reported in baseline data) and the one month follow-up. Scores here represent average level of motivation for change at the time of follow-up. Higher scores represent higher levels of motivation to change, self-efficacy and intention to change.
