“…The portal survey technique conducts a temporal evaluation of substance use and provides pre- and post-assessment of consumption, ensuring the most reliable measure of substance effects. 15 This study also has some limitations. First, the study design is cross-sectional; therefore, we were able to document only the correlations between variables, not the presence of a causal relationship.…”

BackgroundTEN-D by Night is an international, multicentre, cross-sectional portal survey conducted on a large sample of young people in six European countries. This paper aims to investigate the alcohol and psychoactive drug consumption of this sample, with a focus on the prevalence of binge drinking and the poly-drug habits of the TEN-D cohort.Design and MethodsThe study population consisted of 4695 young people attending recreational sites on weekend nights. The intervention included two questionnaires and two psychoactive substance detection tests performed at the entry and exit of the recreational sites. A multivariate logistic regression model was used to predict the probability of binge drinking.ResultsBinge drinking was reported by 20% of the males and 13% of the females (P=0.001) before entry into the recreational sites and by 18% of the males and 11% of the females before entry into the clubs (P<0.001). Poly-drug use was reported by 71% of the males and 66% of the females. Living with a parent (OR 1.57; P=0.01), seeking employment (OR 1.66; P=0.005) and cannabis consumption (several times per month and several times per week, OR 1.94 and 3.66, respectively, P<0.05) were associated with binge drinking.ConclusionsOur survey showed that it is possible to identify individuals and groups at higher risk of binge drinking. This identification would allow for a focus on specific targets and would facilitate the redesign of prevention programmes. The increased use of psychoactive substances among youths should be studied extensively to promote successful prevention campaigns.

“…Data were collected using the portal survey method (Voas et al, 2006), which involves sampling and interviewing groups of individuals before they enter a high-risk environment (e.g., bars, clubs) and resampling the same groups as they leave the environment. This provides the opportunity to collect objective measures of substance use at both entry and exit: breath samples (to test for alcohol) and oral fluid samples (to test for drugs).…”

ABSTRACT. Objective: This research examined the relationship between the intragroup familiarity among peers visiting nightclubs and the likelihood of experiencing negative outcomes. We hypothesized, based on our prior work, that members who are more familiar with their group would be more likely to experience sexual and physical aggression while at the club. Method: The study involved 1,765 young adults (within 654 natural groups) sampled at nightclubs in the San Francisco Bay area. Participants were interviewed about their clubbing history and expectations before entering the club and about their experiences in the club as they exited. Breath samples were collected at both entry and exit to obtain objective measures of alcohol use. Results: Using generalized linear mixed modeling to accommodate correlated data, we found that, to the extent that club patrons were familiar with more of their peer group, the more likely they were to experience sexual and physical aggression, although this was moderated by participant gender. Conclusions: Although in many circumstances group cohesion can be a protective factor, the results of this study suggest that greater group familiarity might sometimes be associated with less concern for safety, reduced vigilance, and an increase in negative experiences.

“…Using portal methodology established in earlier club and other venue-based studies (Miller et al, 2009, 2013; Voas et al, 2006), we approached patrons on the sidewalk by recruiting the first person who crossed an imaginary line on the sidewalk, as they approached the club entry. We used a brief verbal approach, asking patrons if they would be willing to participate in a confidential and anonymous study on nightlife safety for which they would receive $30.00 ($10 at entrance, $20 at exit).…”

“…This includes demographic characteristics and social drinking group influences as our prior work has indicated (Johnson et al, 2012; Miller et al, 2013). In addition, we need to consider that many club patrons often arrive at the club “front-” or “pre-loaded”(Forsyth, 2010; Graham et al, 2014; Miller et al, 2013; Voas et al, 2006). A recent study of club patrons found that 54.9% arrived at the club having consumed alcohol and half of those were impaired or intoxicated (26.3% of the total sample had BAC > .05) (Miller et al, 2013).…”

Objective The current study examines the variation in alcohol use among nightclub patrons under three transportation conditions: those who departed from a club using modes of transportation other than cars or motorcycles (e.g., pedestrians, bicyclists, subway riders); those who were passengers of drivers (auto/taxi passenger patrons); and those who drove from the club (driving patrons). We seek to determine whether patrons' choice for how to leave the club contributes to their risk, as assessed by blood alcohol concentrations (BAC), after controlling for other factors that may contribute to their BAC including demographic characteristics and social drinking group influences. Methods Data were collected from social drinking groups as they entered and exited clubs for 71 different evenings at ten clubs from 2010 through 2012. Using portal methodology, a research site was established proximal to club entrances. Each individual participant provided data on themselves and others in their group. The present analyses are based upon 1833 individuals who completed both entrance and exit data. Our outcome variable is blood alcohol content (BAC) based upon breath tests attained from patrons at entrance and exit from the club. Independent variables include method of transportation, social group characteristics, drug use, and personal characteristics. We use step-wise multiple regressions to predict entrance BAC, change in BAC from entrance to exit, and exit BAC: first entering individual demographic characteristics, then entering group characteristics, then drug use, and finally entering method of transportation (two dummy coded variables such that drivers are the referent category). Results In sum, in all three of our analyses, only three variables are consistently predictive of BAC: presence of a group member who is frequently drunk and non-driving modes of transportation, either being the passenger or taking alternate methods of transportation. In particular, taking an alternate form of transportation was consistently and strongly predictive of higher BAC. Conclusions Additional public health messages are needed to address patrons who are no longer drinking and driving but who are nonetheless engaged in high levels of drinking that may lead to various risky outcomes, for example: being targeted for physical and/or sexual assault, pedestrian accidents, and other adverse consequences. These risks are not addressed by the focus on drinking and driving. Key messages appropriate for patrons who use alternate transportation might include devising a safety plan before entering the club and a focus on sobering up before leaving.
