What was measured

Reinforcing effects of smoking was measured using the modified version of the Cigarette Evaluation Questionnaire. Participants were asked to indicate on a 12-item scale how smoking made them feel in the prior 30 days on a scale from 1 (Not at all) to 7 (Extremely). Higher values indicated that smoking was a more positive experience for 10 of 12 items. Two items were reverse coded. Change in reinforcing effects of smoking was calculated as Follow-up score (6 month) - Baseline Score.

Groups in this outcome

Arm III

Patients receive a nicotine patch, with doses tapering over time for a total of 26 weeks. Patients also receive nicotine gum to quell breakthrough urges. Patients may stop treatment when a comfortable level of smoking abstinence is reached. nicotine: Given transdermally and orally
