TL;DR: Proactive, home-based, and stage-matched expert systems can produce relatively high population impacts on multiple behavior risks for cancer and other chronic diseases.

TL;DR: Three stage-based expert system interventions for smoking, high-fat diet, and unsafe sun exposure were evaluated in a sample of 2,460 parents of teenagers, finding the expert system outperformed the comparison condition across all 3 risk behaviors.

TL;DR: This secondary data analysis combined data from 5 effectiveness trials in which smokers were all proactively recruited from a defined population and all received the same expert system intervention, resulting in a consistent 22% to 26% point prevalence cessation rate across the 5 studies.

TL;DR: Stage-matched manuals provided cessation rates comparable with previous studies, and the addition of NRT, expert system interventions, and automated telephone counseling failed to produce a further increase in intervention effectiveness.

TL;DR: This randomized effectiveness trial evaluated a transtheoretical model (TTM)-tailored intervention to increase condom use and decrease smoking in urban adolescent females and demonstrated effectiveness for increasing consistent condom use at 6 and 12 months, but not at 18 months.
