In this cross-sectional study of US military combat veterans, we assessed the helpfulness of different media for providing health risk communication messages. We have provided preliminary results from a postal survey of 5000 veterans sampled because of their deployment to Vietnam, the Persian Gulf, or Bosnia–Kosovo. Respondents endorsed the primary care provider as the most helpful source of health information. Access to the Internet and use of this medium for seeking health information differed by race, age, and cohort.

More than 200 evaluations of energy conservation programs conducted by California's four major utilities between 1977-1980 were reviewed and critiqued. In general, the evaluations were conducted in the marketing research tradition, were formative (rather than summative), and were dominated by nonexperimental surveys. Major threats to validity included:failure to consider secular economic and attitudinal trends, inadequate prior explication of key constructs, lack of random assignment, lack of appropriate comparison groups, overreliance on attitudes and self-reported behaviors as indices of conservation, and multiple unprotected statistical comparisons. Alternative evaluation techniques designed to reduce validity threats are presented, and a sample of the utilities' more recent work is assessed.

Although testing for alcohol and drug use is common in the U.S. workplace, relatively little is known about the characteristics of workplaces that test and about the consequences to persons tested. This paper describes the link between drug and alcohol testing and the minority composition of worksites. The data come from a 1999 survey of 264 union officials in the telecommunications industry. These preliminary data suggest minority worksites were more likely to perform pre-employment and just-cause testing and less likely to perform random drug testing, even after considering workplace characteristics such as normative use of drugs. A similar but weaker association was found for alcohol testing.
