Randomized controlled trial of the Tobacco Tactics website versus 1-800-QUIT-NOW telephone line among Operating Engineers

Materials and methods Smokers attending workplace safety training groups were randomized to either the Tobacco Tactics website with nurse phone counseling and access to nicotine replacement therapy (NRT) or to the 1-800-QUIT-NOW telephone line which provided an equal number of phone calls and NRT. Participating Operating Engineers completed a baseline survey as well as mailed surveys at 30-days and 6-months. Urinary cotinine tests were used to verify 6-month smoking status. The outcomes were compared using c2 tests, t-tests, mixed models, generalized mixed models, and logistic regression models.
