Saliva thiocyanate: a chemical indicator of cigarette smoking in adolescents.

Denial and minimization in self-reports of cigarette smoking are probable common among youth and other groups where smoking is discouraged. Chemical measures may obtain more accurate measurement of smoking habits in those groups. One such measure, saliva thiocyanate (SCN), was evaluated in 1,419 eighth grade students. In that group, 54.9% of students admitted to regular smoking of greater than one pack/week had thiocyanates greater than or equal to 100 m g/ml compared to 2.3% nonsmokers at those levels. Of students who smoked greater than or equal to 10 cigarettes in the prior 24 hours, 66.7% were at or above 100 microgram/ml. Elevated SCN in nonsmokers was uncommon. Saliva SCN is a safe, inexpensive, and acceptable prevalence measurement for cigarette smoking. It can be used in place of self-reports to document smoking of greater than on pack/week in populations of youth.

Group behavior therapy for problem drinkers.

Twenty-eight problem drinkers participated in behavioral training groups designed to teach moderate drinking. Both at termination and at follow-up, 70% were considered successful, showing significant reduction in alcohol consumption and in weekly peak blood alcohol concentration. Indices of severity of problem drinking were found to best predict outcome. Results are consistent with previous data regarding behavioral self-control training as a therapeutic intervention for early stage problem drinkers.

A probabilistic model of intensive designs.

Without internal validity, experimental data are uninterpretable. With intensive designs, most methods presented to quantify a design's internal validity have been subject to criticism. A probabilistic model of intensive designs is presented that demonstrates the high degree of internal validity of these designs without relying on adaptations from traditional inferential statistics. Where the experimenter is able to conform to the restrictions of the model, the equations provide an estimation of internal validity for either reversal or multiple-baseline designs. More importantly, the model provides mathematical bases for some of the common recommendations and design considerations in intensive research (such as the desirability of within-subject replications and of four or more multiple baselines).

Incorporating social support into a community-wide smoking-cessation contest.

Social support for smoking cessation has been identified as a key factor differentiating which individuals are most likely to quit smoking. Attempts to enhance social support in clinic-based programs have generally been unsuccessful. This study investigated a strategy for increasing the involvement of supportive others among participants in a community-based smoking-cessation contest. These smokers were undertaking quit attempts without the supportive environment offered in clinic-based group programs. Subjects included 734 adult smokers who had participated in a smoking-cessation contest in their local community. Contest participants had the option of designating a "support person" who would assist them in quitting smoking and be eligible for prizes if the participant was a contest winner. Follow-up was by telephone survey 3 months after the end of the contest. No differences were observed in demographic or smoking history variables between those who did and did not elect to name a support person. A relatively high proportion (60%) of contest participants elected to identify a support person and self-reported smoking-cessation rates were significantly better among those who named a support person than among those who did not. Identifying a support person was a particularly effective strategy for those with smoking or nonsupportive spouses.

Women and smoking: issues and opportunities.

In March 2001, the U.S. Surgeon General released Women and Smoking, the second Surgeon General's report to focus on tobacco use among women, compelling the nation to make reducing tobacco use among women one of the highest priorities for women's health. Since 1980, 3 million women have died prematurely from smoking-related diseases and injuries. Lung cancer mortality rates among U.S. women have increased about 600% since 1950, and now lung cancer is the leading cause of cancer death among U.S. women, having surpassed breast cancer in 1987. Although the report documents the devastating impact of the tobacco epidemic among women, a growing arsenal of science-based recommendations for implementing comprehensive tobacco control programs suggests that achieving the nation's ambitious Healthy People 2010 objectives, including cutting in half the rates of smoking among women and girls, is within our reach. While states continue to debate the use of tobacco settlement funds, it is important to note that when significant resources have been devoted to the implementation of evidence-based strategies, the results have been dramatic for the population overall and for women in particular. For example, in California, which has had a comprehensive tobacco control program for 11 years, smoking prevalence has declined throughout the 1990s at rates two or three times faster than in the rest of the country, and while lung cancer incidence rates increased by 13% among women in other parts of the United States, they decreased by 4.8% among women in California. These promising findings indicate that although tobacco-related diseases have become a women's health issue of epidemic proportions, we have the ability to reverse these trends.
