OBJECTIVES This longitudinal study examined the prevalence and correlates of energy drink use among college students, and investigated its possible prospective associations with subsequent drug use, including nonmedical prescription drug use. METHODS Participants were 1,060 undergraduates from a large, public university who completed three annual(More)
BACKGROUND Energy drinks are highly caffeinated beverages that are increasingly consumed by young adults. Prior research has established associations between energy drink use and heavier drinking and alcohol-related problems among college students. This study investigated the extent to which energy drink use might pose additional risk for alcohol dependence(More)
STUDY OBJECTIVE To define, among a sample of college students, the nature and extent of nonmedical use of prescription stimulants (NPS), including both overuse and use of someone else's drug, for attention-deficit-hyperactivity disorder (ADHD); to characterize NPS among individuals not medically using a prescription stimulant for ADHD; and to determine(More)
This study describes the level of perceived harmfulness of nonmedical prescription stimulant and analgesic use in a sample of college students, and examines the prospective relationship between perceived harmfulness and subsequent nonmedical use. In addition, we explore whether the association between perceived harmfulness and nonmedical use varies by level(More)
This study tested the hypothesis that college students' substance use problems would predict increases in skipping classes and declining academic performance, and that nonmedical use of prescription stimulants (NPS) for studying would occur in association with this decline. A cohort of 984 students in the College Life Study at a large public university in(More)
Underage drinking and drug use among college students are major public health concerns, yet few studies have examined these behaviors and their associated risk factors and consequences prospectively. This paper describes the sampling and recruitment methods of a longitudinal study of 1253 college students at a large, mid-Atlantic university. Incoming(More)
BACKGROUND Research has linked heavy alcohol use with nonmedical prescription analgesic use, but no studies have focused on concurrent use. OBJECTIVES To understand the extent to which alcohol use and nonmedical prescription analgesic use co-occur among college students. METHODS The Timeline Followback method was used to split the sample (n = 1,118)(More)
The goal of this study was to develop a multi-dimensional model that might explain suicide ideation among college students. Face-to-face interviews were conducted with 1,249 first-year college students. An estimated 6%(wt) of first-year students at this university had current suicide ideation. Depressive symptoms, low social support, affective(More)
BACKGROUND College drinking is a significant public health problem. Although parental monitoring and supervision reduces the risk for alcohol consumption among younger adolescents, few studies have investigated the impact of earlier parental monitoring on later college drinking. This study examined whether parental monitoring indirectly exerts a protective(More)
BACKGROUND Despite the relatively high prevalence of marijuana use among college students, little information exists regarding health outcomes associated with different use patterns or trajectories. METHODS Seven annual personal interviews (years 1-7) were administered to 1253 individuals, beginning in their first year in college. Growth mixture modeling(More)
