“…In the current experiment employing a repeated alcohol deprivation paradigm, P rats upon re-exposure displayed a pronounced level of ETOH responding, and hence intake, for up to 5 days, and increased the amount of work they were willing to perform to obtain access to ETOH. Thus, repeated deprivations invoked a drinking pattern in P rats very similar to that of binge drinking observed in human alcoholics (Finney and Moos, 1991;Nezlek et al, 1994), and may have enhanced the reinforcing properties of ETOH in this selectively bred line of rats. Therefore, repeated alcohol deprivations, which more closely model the human alcohol-drinking pattern (McMillen, 1997), may be more valid than the singledeprivation ADE procedure for studying relapse/craving and 'binge' drinking.…”

We reported that repeated alcohol deprivations prolonged the expression of an alcohol-deprivation effect (ADE) under 24-h freechoice alcohol-drinking access and that the duration of the initial deprivation period had a positive effect of prolonging the duration of the ADE. In the present study, operant techniques (including progressive ratio measures) were used to examine the effects of initial deprivation length and number of deprivation cycles on the magnitude and duration of the ADE in alcohol-preferring (P) rats to test the hypothesis that repeated deprivations can increase the reinforcing effects of ethanol (ETOH). Adult male P rats were trained in two-lever operant chambers to self-administer 15% ETOH (v/v) on a fixed-ratio 5 (FR-5) and water on a FR-1 schedule of reinforcement in daily 1-h sessions. Following 6 weeks of daily 1-h sessions, the P rats were randomly assigned to one of four groups (n ¼ 10/group): nondeprived or deprived of alcohol for 2, 5, or 8 weeks. Following this initial period, the deprived groups were given 15% ETOH again in the operant chambers for a 2-week period, following which they were deprived again for 2 weeks (all three deprived groups). Following the fourth deprivation, the rats underwent a progressive ratio test to determine the breakpoints (FR values) for the nondeprived and the deprived groups. Repeated deprivations increased both the magnitude and duration of the ADE as indicated by increased responding on the ETOH lever. However, the length of the initial deprivation had little effect on expression of the ADE except following the first deprivation, where an ADE was not observed for the 8-week group. Breakpoint values for responding on the ETOH lever for all three deprived groups were two-fold higher than the value for the nondeprived group. The results suggest that repeated cycles of alcohol deprivation and alcohol access increased the reinforcing effects of ETOH in the P rats.

“…Repeated EDE cycles closely resemble human alcohol drinking patterns (Finney and Moos, 1991;McMillen, 1997;Nezlek et al, 1994). The drinking pattern of human alcoholics is correspondingly segmented by multiple periods of abstinence and intake (Burish et al, 1981;Hilbrom, 1990;McMillen, 1997).…”

Ethanol craving plays a major role in relapse drinking behavior. Relapse and ethanol craving are an important focus for the treatment of alcoholism. The ethanol deprivation effect (EDE) is a widely used animal model of alcohol craving. While the EDE is widely studied in rats, the molecular mechanisms underlying EDE are not clearly understood. The C57BL/6 inbred mouse strain is widely used for behavioral and molecular analyses of ethanol drinking but studies on the EDE have not been reported in this strain. In the present study, we characterized a simple behavioral protocol that rapidly and reliably induced EDE in C57BL/6 mice. Briefly, singlehoused adult male C57BL/6NCrl and C57BL/6J mice were presented at the beginning of dark phase with two-bottle choice drinking containing either 10 % w/v ethanol or tap water for 18-hrs/ day, as well as food ad libitum. Following ethanol drinking for 4 days or 14-days, mice were deprived of ethanol for a period of 4 days. To study EDE, mice were reinstated with two-bottles containing either ethanol (10 % w/v) or water. Mice were exposed to single or multiple ethanol deprivation cycles. Ethanol consumption (g/kg/18-hrs) and percent ethanol preference (% preference/18-hrs) was recorded for individual mice. C57BL/6NCrl mice consumed moderate amounts (4.78 ± 0.63 g/kg) of ethanol but showed robust EDE after ethanol drinking episodes (4 days or 14 days) as evidenced by increased ethanol consumption and ethanol preference following re-instatement of ethanol. While repeated ethanol deprivation in C57BL/6NCrl mice transiently increased ethanol consumption and ethanol preference, the magnitude of these behaviors was reduced as compared to the first deprivation cycle. In contrast, the C57BL/6J substrain consumed substantially higher levels (9.65 ± 0.90 g/kg) of ethanol but did not show a clear EDE after single or multiple ethanol deprivation cycles. In conclusion, we established a simple and reliable behavioral model to study EDE in C57BL/6NCrl mice. A reliable behavioral model to study EDE in inbred C57BL/6NCrl mice could greatly facilitate further studies on molecular mechanisms of ethanol craving behavior.

“…Among the current sample of university students, male binge drinkers were more likely to report higher life satisfaction (or quality of life) than non-binge drinkers, but no such difference was evident for females. Interestingly, there is some evidence to suggest alcohol consumption may be associated with positive social consequences (Nyström, 1992;Park, 2004) for university students, such as increased intimacy and self-disclosure in social interactions (Nezlek et al, 1994). In fact, Nezlek et al (1994) suggest that some level of occasional binge drinking may actually be normative and is associated with fuller integration into the collegiate community compared to students who have too many, or no, episodes of binge drinking.…”

In fact, Nezlek et al (1994) suggest that some level of occasional binge drinking may actually be normative and is associated with fuller integration into the collegiate community compared to students who have too many, or no, episodes of binge drinking. The present findings seem in line with this possibility, at least for males, as many binge drinkers fell in the "once in the past 30 days" or "1 to 2 times per week" frequency categories.…”

“…In talking about social alienation, some studies have shown how people susceptible to peer pressure, and people with more friends, are more likely to engage in binge drinking (Talbott et al, 2008;Weitzman et al, 2003;Wechsler & Kuo, 2000); however, other findings have indicated that individuals who report feelings of loneliness or fewer social interactions are more likely to engage in such behaviour (Knox, Vail-Smith, & Zusman, 2007;Nezlek, Pilkington, & Bilbro, 1994). No studies that we are aware of have explored the relationship between binge drinking and a validated or complete measure of social alienation among university students.…”

Abstract:There is a lack of recent research exploring the differences between binge and non-binge drinkers among Canadian university students. The current study aims to address this gap in the literature through an exploratory statistical analysis. Univariate, bivariate, and multivariate (logistic regression) analyses were employed to identify the prevalence of binge drinking, as well as its various sociodemographic, behavioural, and mental health correlates. A large majority (83.1%) of the 507 respondents reported consuming alcohol in the previous 12 months; of these, 69.7% (67.0% of males, 70.9% of females) reported engaging in binge drinking (5 drinks in one session for males, 4 for females) at least once in the previous 30 days. Although there was no significant gender difference in the prevalence of binge drinking, there were several gender differences among the correlates. Compared to non-binge drinkers, male binge drinkers reported greater life satisfaction, and greater probability of smoking cigarettes and engaging in risky sex, while females reported greater impulsivity and lower religiosity. As expected, binge drinkers experienced more adverse consequences from alcohol consumption than did non-binge drinkers, but unexpectedly did not differ significantly in mental health and wellbeing. Limitations of the present study and future research directions are discussed with a view to improving our understanding of risk and protective factors related to unhealthy alcohol consumption among university students in Canada and abroad.Keywords binge drinking; alcohol research; university students; Canada; mental health Tamara Edkins MA is a student in the Faculty of Law at the University of Manitoba, 224 Dysart Rd., Winnipeg, MB R3T 2N2.
