Correlates of motivation to quit smoking in methadone-maintained smokers enrolled in a smoking cessation trial.

Cigarette smoking is a clear problem among methadone-maintained persons, yet little is known about factors that may be associated with their motivation to quit smoking. A sample of 255 smokers, enrolled in a smoking cessation research protocol, completed measures of their smoking motivation, smoking habit, quitting history, and intent to quit in the future. Both zero-order correlational and multivariate linear regression analyses indicated that only number of cigarettes smoked per day and expectancies for success with smoking cessation were associated significantly with motivation to quit smoking. These results have implications for understanding motivational processes among methadone-maintained smokers and may help in the design of interventions that will assist this population with quitting smoking.
