Ex-smokers (N = 61) who had stopped smoking as part of a televised "clinic" were assigned to either a tape-reinforcement or nonreinforcement condition and were followed up a month later. A self-regulated reward system can be an extremely cost-effective tool in preventing short-term recidivism among neophyte ex-smokers. (Author)
