|---|
Smoking cessation interventions have posed significant challenges for health professionals, particularly when directed at high risk, low income, pregnant smokers. Typical quit rates for pregnant women who receive publicly financed obstetrical care have rarely exceeded 12-16%.1 As many as 70% of women who quit smoking during pregnancy relapse within one year of delivery.2 Two areas that have received particular attention as possible adjuncts to behaviour change are the use of reinforcements and social supports. Reinforcement in the form of incentives/rewards for positive behaviours has been controversial as an intervention strategy. Some argue that the "overjustification effect" of external rewards may cause subjects to lose internal motivation to modify behaviour over the long term.3 However, results of several studies, including two meta-analyses on reinforcement, provide compelling evidence that positive reinforcement provides positive behavioural changes.4-8
