Substantial correlational evidence supports a causal (mediational) interpretation of alcohol expectancy operation, but definitive support requires a true experimental test. Thus, moderately to heavily drinking male college students were randomly assigned to 1 of 3 conditions in a pre-post design: Expectancy challenge (designed to manipulate expectancy(More)
Expectancies' mediational (control) role in alcohol consumption has been supported by both correlational and experimental evidence (J. Darkes & M. S. Goldman, 1993; M. S. Goldman, P. E. Greenbaum, & J. Darkes, 1997; L. Roehrich & M. S. Goldman, 1995). This study assigned participants (n = 54) to 1 of 2 expectancy challenges targeting the expectancy(More)
Surveys have documented excessive drinking among college students and tracked annual changes in consumption over time. This study extended previous work by examining drinking changes during the freshman year, using latent growth curve (LGC) analysis to model individual change, and relating risk factors for heavy drinking to growth factors in the model.(More)
Recently, Del Boca, Darkes, Greenbaum, and Goldman (2004) examined temporal variations in drinking during the freshmen college year and the relationship of several risk factors to these variations. Here, using the same data, we investigate whether a single growth curve adequately characterizes the variability in individual drinking trajectories. Latent(More)
Despite several decades of activity, alcohol expectancy research has yet to merge measurement approaches with developing memory theory. This article offers an expectancy assessment approach built on a conceptualization of expectancy as an information processing network. The authors began with multidimensional scaling models of expectancy space, which served(More)
Four papers from a 2001 Research Society on Alcoholism symposium on expectancy theory and research are summarized. The symposium contributors describe recent advances in expectancy theory and discuss their implications for assessment and for understanding the processes of development and change in the behavioral domain of alcohol use. First, findings are(More)
This article presents the proceedings of a symposium at the 2002 RSA Meeting in San Francisco, organized by Reinout W. Wiers and Mark D. Wood. The symposium combined two topics of recent interest in studies of alcohol expectancies: cognitive mechanisms in expectancy challenge studies, and context-related changes of expectancies. With increasing recognition(More)
BACKGROUND Rule violations among elite-level sports competitors and tragedies among adolescents have largely defined the issue of non-medical anabolic-androgenic steroid (NMAAS) use for the public and policy makers. However, the predominant and oft-ignored segment of the NMAAS community exists in the general population that is neither participating in(More)
OBJECTIVE This study investigates college students' behaviors in response to the calories ingested by drinking alcohol. PARTICIPANTS AND METHODS A sample of 274 nonclinical undergraduate alcohol drinkers completed an online survey asking about behaviors that students employed to make up for calories in alcohol or to get drunk more effectively. Drive for(More)
Alcohol expectancies' mediation of many known antecedents' influence on drinking has been well established, but most models have omitted theoretically relevant mediational pathways through both common (overlapping) and unique (nonshared) expectancy variance. The authors of this study evaluated expectancy mediation using a hierarchical expectancy model that(More)
