data on the current sample revealed that compared with prepartiers who did not report
blacking out during the past month, male and female students who did report a blackout
drank approximately twice as much during a typical week and consumed more drinks during
a typical prepartying occasion. Further, approximately 56% of males and 50% of females
who had experienced a blackout while prepartying engaged in heavy episodic drinking
during a typical prepartying event compared with only 27% of males and 23% of females
who did not experience a blackout. Although the actual duration of drinking events and
subsequent timing of the ensuing blackout was not directly assessed in this study, fast-paced
drinking during prepartying (Pedersen&LaBrie, 2007) is likely associated with reductions in
judgment and minimization of potential consequences (Fromme, Katz, & D’Amico, 1997),
whereby leading to heavier drinking following the prepartying event later in the night.
Indeed, the amount of alcohol consumed during prepartying directly predicts the amount
consumed afterwards (Pedersen & LaBrie, 2007). These links further categorize prepartying
as a risky behavior with the potential for quickly elevated BACs leading to blacking out and
potentially dangerous negative consequences associated with blacking out.
Chi-square tests revealed bivariate relationships between blacking out and the following
factors: being male, being Caucasian, Greek status, family history of alcohol abuse,
prepartying more frequently, prepartying while playing drinking games, and, not
surprisingly, consuming larger amounts of alcohol during prepartying, whether it be beer,
wine, shots, or mixed drinks. Of notable interest is that age did not play a role in
discriminating among students who reported blacking out while prepartying. Although the
genesis of prepartying is not known, one possible speculation is that it emerged from
underage drinkers (those under the legal drinking age of 21 in the United States) not having
access to alcohol once they go out for the evening. For example, underage students may
consume alcohol prior to attending a club that requires students be 18 years of age to enter
but 21 or older to consume alcohol. In addition, concert venues, sporting arenas and
stadiums, or school-sponsored events often are either alcohol free or require that students be
of legal drinking age in order to consume alcoholic beverages. This may be why in one
study that specifically focused on reasons for prepartying among a young college-aged
population, males and females reported arriving to a social event already under the influence
as their most highly endorsed reason for prepartying (Pedersen et al., 2009). Yet while
prepartying is popular among underage drinkers seeking intoxication whether it be before a
school-related function, party, social, or sporting event, it also remains popular among
students of legal drinking age. Previous studies have found no differences between underage
and of-age participants on the number of drinks consumed while prepartying or the
frequency of prepartying in the past month (e.g., Glindemann, Ehrhart, Maynard, & Geller,
2006; Pedersen et al., 2009). Coupled with the current results, it appears that risky drinking
behaviors, such as prepartying, may need to be demythologized as a primarily first-year
student or underage drinking phenomenon.
Previous research has identified factors such as being Caucasian (Office of Applied Studies,
2008; O’Malley & Johnston, 2002), Greek status (Larimer, Anderson, Baer, & Marlatt,
2000; Park, Sher, & Krull, 2008), possessing a family history of alcohol misuse (Warner,
White, & Johnson, 2007), drinking frequently (Borsari, Neal, Collins, & Carey, 2001), and
playing drinking games (Borsari et al., 2007) to be associated with risky or problematic
LaBrie et al.
