Randomized Controlled Trial
Correcting over 50 years of tobacco industry misinformation.
In 2006, a U.S. Federal Court ruled that the major domestic cigarette manufacturers were guilty of conspiring to deny, distort, and minimize the hazards of cigarette smoking to the public and ordered corrective statements to correct these deceptions. ⋯ Each of the proposed corrective statements tested helped correct false beliefs about smoking, but sustained impact will likely require repeated exposures to the message.

Randomized Controlled Trial
Effectiveness of a web-based colorectal cancer screening patient decision aid: a randomized controlled trial in a mixed-literacy population.
Colorectal cancer (CRC) screening reduces mortality yet remains underutilized. Low health literacy may contribute to this underutilization by interfering with patients' ability to understand and receive preventive health services. ⋯ The web-based decision aid increased patients' ability to form a test preference and their intent to receive screening, regardless of literacy level. Further study should examine ways the decision aid can be combined with additional system changes to increase CRC screening.
