The recent popularity of models that capture the dynamic coevolution of both network structure and behavior has driven the need for summary indices to assess the adequacy of these models to reproduce dynamic properties of scientific or practical importance. Whereas there are several existing indices for assessing the ability of the model to…

This study explored substance use trajectories and associations with mental health among an ethnically/racially diverse college student sample before and during the COVID-19 pandemic. We combined repeated cross-sections and panel data from a total of 3,247 college students assessed with an online survey in 2018, 2019, and in three waves in 2020.…

Background: Identifying effective relapse prevention interventions is a vital step to help smokers maintain abstinence for the long term. Aims: The purpose of this study is to determine if providing recently quit smokers with self-directed relapse prevention booklets is effective at maintaining abstinence after intensive group smoking cessation…

The theory of planned behavior identifies important proximal determinants of behavior, including attitude toward the behavior, perception of subjective norms exerted by significant others, and perception of perceived control over performance of the behavior. Because research in the planned behavior tradition has focused on desirable target…

Compared a broad-spectrum treatment against a control limited to one week of aversive conditioning. Results indicated a dramatic treatment effect, with 76 percent of experimental subjects (as compared to 35 percent of controls) remaining abstinent at a six-month follow-up. (Author)

Investigated efficacy of combining rapid smoking aversion and training in self-control skills for maintaining nonsmoking. Results at the 13-week follow-up showed that the performance of the combined rapid smoking plus self-control program was not superior to rapid smoking plus disucssion. (Author)

The role of environmental stimuli in the control of cigarette smoking has been the object of theoretical speculation, but there have been few experimental demonstrations of the control exerted over smoking by environmental events. Self-report data on smoking in the natural environment were compared to observations made of smoking among subjects…

Periodically, Maryland's sixth, eighth, tenth, and twelfth graders are surveyed to determine the nature, extent, and trend of alcohol, tobacco, and other drug (ATOD) use among adolescents. The "2007 Maryland Adolescent Survey (MAS)" presents the latest findings regarding ATOD use by Maryland's adolescents and compares State and local…

Kruglanski's endogenous-exogenous partition, when applied to reasons given by smokers for smoking cigarettes, distinguishes two types of actions: (1) endogenous reasons implying that the behavior of consuming the cigarette is the goal of the action and the actor is positive toward the behavior, and (2) exogenous reasons implying that the behavior…

Jones and Hartmann (1988) investigated the relation between identity status and experimental substance use among adolescents in junior and senior high schools, identifying differences in substance use across four identity statuses for adolescents in general. This study was conducted to examine the generalizability of these differences across…
