This paper summarizes the proceedings of a symposium presented at the 2005 Research Society on Alcoholism meeting in Santa Barbara, California, that spans the interval from toddlerhood to early middle adulthood and addresses questions about how far ahead developmentally we can anticipate alcohol problems and related substance use disorder and how such work informs our understanding of the causes and course of alcohol problems and alcohol use disorder. The context of these questions both historically and developmentally is set by Robert Zucker in an introductory section. Next, Maria Wong and colleagues describe the developmental trajectories of behavioral and affective control from preschool to early adolescence in a high risk for alcoholism longitudinal study and demonstrate their ability to predict alcohol and drug outcomes in adolescence. Duncan Clark and Jack Cornelius follow with a report on the predictive utility of parental disruptive behavior disorders in predicting onset of alcohol problems in their adolescent offspring in late adolescence. Next, Kenneth Leonard and Gregory Homish report on adult development study findings relating baseline individual, spouse, and peer network drinking indicators at marriage onset that distinguish different patterns of stability and change in alcohol problems over the first 2 years of marriage. In the final paper, John Schulenberg and colleagues, utilizing national panel data from the Monitoring the Future Study, which cover the 18- to 35-year age span, show how trajectories of alcohol use in early adulthood predict differential alcohol abuse and dependence outcomes at age 35. Finally, Robert Zucker examines the degree to which the core symposium questions are answered and comments on next step research and clinical practice changes that are called for by these findings.

This article summarizes a symposium organized and cochaired by Maria Testa and presented at the 2005 Annual Meeting of the Research Society on Alcoholism, in Santa Barbara, California. The symposium explored issues relevant to understanding the function of placebo conditions and to interpreting placebo effects. Cochair Mark Fillmore began with an overview of the use of placebo conditions in alcohol research, focusing on methodological issues. Jeanette Norris and her colleagues conducted a review of studies examining placebo conditions among women. They conclude that expectancy effects are limited to a few domains. Maria Testa and Antonia Abbey presented papers suggesting that placebo manipulations may result in unanticipated compensatory effects in actual or hypothetical social situations. That is, placebo participants may compensate for anticipated cognitive impairment through vigilant attention to situational cues. John Curtin's research suggests that the compensatory strategies of placebo participants appear to involve a sensitization of evaluative control, resulting in improved performance. Kenneth Leonard provided concluding remarks on the meaning of placebo effects and the value of placebo conditions in research. [ABSTRACT FROM AUTHOR]
