The decision aid increased knowledge of cessation methods and induced a more positive attitude towards these methods. Furthermore, 45% reported increased confidence about being able to quit and 43% said it helped them to choose between treatments. However, no clear effect on usage of treatment aids was found, but the intervention group had more quit attempts (OR=1.52, 95% CI 1.14-2.02) and higher point prevalence abstinence at 6-month follow-up (20.2% versus 13.6%; OR=1.51, 95% CI=1.07-2.11). CONCLUSIONS An aid to help smokers decide to use efficacious treatment when attempting to quit smoking had a positive effect on smoking cessation, while failing to increase the usage of efficacious treatment. This finding lends support to the notion that the mere promotion of efficacious treatments for tobacco addiction might increase the number of quit attempts, irrespective of the actual usage of treatment.
