Tailored communications for smoking cessation: past successes and future directions.

Tailored communications are one of the most promising approaches to smoking cessation interventions for entire populations. Assessments based on the Transtheoretical Model are processed by computer-based expert systems that generate feedback reports tailored to each individual to accelerate their progress through the stages of change for smoking cessation. Seven studies are reviewed that range from a more traditional clinical trial to trials on entire populations of smokers to population trials designed to change multiple behaviours, including smoking. A series of three tailored communications was found to produce long-term point prevalence abstinence rates within the narrow range of 22-26% abstinence. This same range of abstinence was found even when two or three other behaviours (e.g. diet and sun protection) were treated in the population. These results point to a future in which health behaviour risk interventions will be assessed not solely by their efficacy but by their population impact.
