The development of new cancer therapies requires additional, and more complex, clinical trials. But only approximately 3% to 5% of adult cancer patients participate in cancer clinical trials. This study seeks to identify and understand the attitudes of the public and cancer survivors toward health-related decisions and cancer clinical trials to identify the key factors that must be addressed to increase that percentage.

The Perceived Stress Scale (PSS) is a widely used measure of stress that has not been validated in asthma patients. The psychometric properties of the PSS were explored using confirmatory factor analysis and item response theory. Study 1 involved 312 ambulatory care patients with asthma who completed the PSS during a routine visit. Study 2 involved 247 community-dwelling adults with asthma who completed the PSS as a part of a larger asthma study. Four items showed acceptable psychometric performance across ethnic groups and literacy. The short PSS is a rapid, valid measure of subjective stress in diverse asthma populations.

American adults learn about science and health from numerous sources including television. The Pew studies demonstrate that half of American adults watch a local television news show three times a week or more, making local television news the most widely used news medium. This study examines the impact of a program to increase the use of science and health stories in local newscasts. The results show substantial story recall and information retention. The analysis suggests that science and health stories in local television newscasts may either enhance viewers' existing science/health schemas or foster the development of new schemas for less well-known constructs.
