"Financial incentives for smoking cessation"

Quitting smoking is easier if you receive a reward for it. This research shows that employees refrained from smoking better if they received a reward in combination with quit-smoking training at work.

The research involved 604 smokers who wanted to stop smoking from 61 companies in the Netherlands. Half of the smokers participated in a group training only (control group) and the other half participated in the group training and received a reward (intervention group). The reward consisted of gift certificates totalling €350. After the training, those who had stopped smoking received €50, after three months another €50, after six months again €50 and after 12 months €200. After a year, some people had started smoking again, but there was a large different between the intervention and control groups (41% vs. 26%).

This demonstrates that a quit-smoking group training at work will be more successful if combined with a reward in the form of gift certificates. The results of this research have been published in the leading scientific journal The Lancet Public Health, among others.
