Marijuana use among U.S. college students is the highest since the mid-1980s. Because knowledge about marijuana and confidence in the knowledge are related to changing marijuana laws and marijuana-related messages ubiquitous in college students' information environment, we examined their relationships with use. The Structural Equation Modeling…

Alcohol remains readily available to youth in most countries. We examined the associations between both the on- and off-premises commercial availability of alcohol to youth and their alcohol use, heavy episodic drinking, and alcohol-related harms. We conducted the study using data from a survey of a sample of 594 students in central Mexico between…

In this study, we examined how the number of friends and leadership among peers related to e-cigarette use and beliefs about the social consequences of use among college students. Data were collected via web survey from 175 university students in 2016. Regression techniques were used to analyze responses. Neither number of friends nor role in a…

There is increasing evidence that mental health problems may attenuate the relationship between protective behavioral strategies (PBS) and alcohol outcomes. However, psychological distress may also affect these relationships. Further, it appears that different types of PBS have differential relationships with alcohol outcomes. The current study…

In this longitudinal study (N = 98), we examined whether drinking for suppression reasons moderated the relation between depressive symptoms and hooking up for self-affirmation reasons and negative hookup consequences. No moderation was found for hooking up for self-affirmation reasons, but the effect for negative hookup consequences approached…

Persons with mental illness smoke at rates two to four times higher than do persons without mental illness and comprise 30.9% of the U.S. tobacco market. Given the prevalence of mental illness and the known detrimental effects of tobacco, concerted efforts are needed to promote the use of evidence-based treatment options. We conducted a systematic…

This investigation examined the association between alcohol and other drug (AOD) prevention/education programs and drinking behaviors among students aged 12 to 17 years. We conducted a secondary analysis of the 2013 National Survey on Drug Use and Health (N = 17,736). AOD prevention/education was assessed in three school settings: special class,…

The purpose of this research was to examine how affective associations with smoking and outcome expectancies regarding smoking are related to smoking status and intention to quit among smokers. Researchers and practitioners can draw on findings regarding affective associations and outcome expectancies to provide a further basis for smoking…

Methamphetamine use has been identified as having significant adverse health consequences, yet we know little about the correlates of its use. Additionally, research has found that Native Americans are at the highest risk for methamphetamine use. Our exploratory study, informed by the stress process model, examines stress and stress buffering…

The current study examined the degree to which associations that protective behavioral strategy use had with alcohol consumption and alcohol-related negative consequences were moderated by disordered eating and race. Participants were 382 female undergraduates (ages 18-25) who had consumed alcohol at least once within the previous month.…

This study examined relationships between emotional self-efficacy (ESE) and alcohol and tobacco use in a statewide sample of public high school adolescents (n?=?2,566). The Center for Disease Control Youth Risk Behavior Survey and an adolescent ESE scale were utilized. Logistic regression analyses indicated the presence of any significant race by…

This study evaluated the efficacy of "Above the Influence" (ATI), a national media-based health persuasion campaign to deter youth drug use. The campaign uses public service anti-drug prevention messages and targets youth between the ages of 14 and 16, a period of heightened susceptibility to peer influences. The evaluation utilized mall…

In the present study, we describe correlates of 30-day cigarette and alcohol use among two samples of high school students, one in the Russian Federation (n = 365), and one in the United States (n = 965). The correlates used in the analyses are based on the theory of triadic influence, which organizes predictors of adolescent substance use into…

Objective: Alcohol abuse among college students is associated with a quality of life burden. The current study replicated and extended previous research on protective behavioral strategies (PBS) by examining relationships between PBS use and negative alcohol-related consequences. Method: A national sample of 29,792 U. S. college students who…

In response to the problem of adolescent smoking and limited appropriate cessation resources, this study examined the pattern and structure of the American Lung Association, Why Do You Smoke? (WDS) to determine its appropriateness for use in youth smoking cessation programs. The WDS is used to help smokers identify primary motivations for using…
