Students Student Drinking Spring 2013 INTRODUCTION This survey, conducted by Student Affairs Research and Assessment, provides data on alcohol use and high-risk drinking behavior of undergraduate students at University Park. Survey questions focus on students' alcohol consumption, the direct and indirect consequences of that consumption, and protective and risk behaviors associated with drinking. While this topic has been assessed regularly since 1995, the survey was significantly revised in 2008 with the assistance of Dr. Rob Turrisi and staff in the Penn State Prevention Research Center and has been conducted annually since that year. Although some pre-2008 comparisons can be made, other findings are only comparable to data gathered since 2008. Primarily, 2011 data (the most recent prior administration) are presented in this report for comparison. Data from other years are available at http://studentaffairs.psu.edu/assessment/alphapulse.shtml. This survey was administered by email/web. At University Park, a random sample of 4,990 undergraduate students was invited to participate. In total, 1,174 students completed the survey for a 23.5% response rate. The confidence interval for the resulting sample is +/-2.86%. Of the respondents, 55.8% were female and 44.2% were male; 83.0% were 18 to 20 years old; and 57.4% lived off campus. Seventy-eight percent were White domestic students, 14.4% were domestic Students of Color, and 6.1% were international students (1.7% were of unknown race).

Drinks per Hour In addition, 57.0% indicated they had tried alcohol (more than a few sips) prior to the age of 18. While 20.1% reported they have never gotten drunk, 43.6% had gotten drunk for the first time prior to the age of 18. Quantity of Consumption Students were asked about their drinking behavior on Wednesday, Thursday, Friday, and Saturday nights of a typical week during this academic year. Roughly two-thirds of students reported drinking on Friday and Saturday nights of a typical week, whereas 13.5% reported drinking on Wednesday nights and 37.0% on Thursday nights (Table 1). The percentage of students who reported drinking on a given night was lower than it was in 2011 (Table 1). The average numbers of drinks per hour of students who drink on a given night was about the same as in 2011 and down slightly compared to 2008 (Figure 2). The Blood Alcohol Content (BAC) levels of students who drink were higher on the weekends at.09 on Friday and Saturday nights compared to.05 on Wednesday and.07 on Thursday evenings (Table 1). The BAC levels of students for each night in the 2013 administration were slightly higher than those of students in 2011 (Table 1). Table 1.

During the current academic year, 19.5% of students indicated they got drunk on 7 or more days during a typical month, whereas 29.1% indicated they don t drink or didn t get drunk. In comparison, 59.4% of students reported that they did not get drunk during a typical month of their senior year in high school and only 3.7% got drunk 7 or more days. Men, White students, students of legal drinking age, and off-campus students reported getting drunk significantly more frequently during a typical month of the current academic year than their respective counterparts (analysis not shown). 2

On that occasion, students averaged 7.42 drinks over 3.89 hours. 63.7% of students who drink consumed two or less drinks per hour (Figure 4) during peak drinking occasions, with an overall average of 2.12 drinks per hour, compared to an average of 2.09 in 2011. Students, on average, reported drinking at this peak volume 2.84 times during the three-month period. Fortyeight percent reported drinking at a peak level 1 to 2 times; 15% said 3 to 4 times; and 16% said 5 or more times (with 22% reporting they didn t drink). While 22.4% of students who drink (compared to 27.0% in 2011) reported peak drinking behavior resulting in a BAC of.079 or lower (below the legal limit of.080), 22.8% indicated a BAC of.250 or higher (Figure 5).

Percent Students High-Risk Drinking High-risk, or binge drinking, is defined as having four or more drinks in a two-hour period for women and five or more drinks in a two-hour period for men. Frequent high-risk drinkers are those students who report having binged three or more times during a two-week period. Occasional high-risk drinkers are those who report having binged one or two times during a two-week period. Just under half of the respondents (43.9%) reported engaging in high-risk drinking behavior in the previous two weeks with 16.6% being classified as frequent high-risk drinkers (Figure 6). These data indicate a slight decline in high-risk drinking since 2008, when 52.8% of students reported engaging in this activity. Similar to previous years, men engaged in high-risk drinking at a greater rate than women (46.5% compared to 41.7% respectively), though the difference is not statistically significant (Figure 7). The 2008-13 high-risk drinking rates are lower than what had been reported in recent years (58.9% in 2006, 55.2% in 2004, and 60.4% in 2003). The question, however, was revised in 2008 which may account for the difference. Since 2008, the question has been based on the number of drinks consumed during a two-hour period as compared to in one sitting or in a row that had been asked in the previous years. Figure 6. Number of Times Students Engaged in High-Risk Drinking During a Two-Week Period 47.2% 56.2% 52.5% 28.7% 28.8% 27.3% 14.6% 12.6% 10.7% 9.4% 6.0% 5.9% 0/don't drink 1-2 times 3-4 times 5 or more times Figure 7.

Off-campus students were significantly more likely than on-campus students to report engaging in high-risk drinking. Evidence suggests a significant inverse relationship between high-risk drinking and GPA (Figure 8). 4

These perceptions of alcohol use are compared to the actual reported behavior for female and male students in Figure 9. As demonstrated, students perceive a higher quantity of alcohol consumed than what is actually reported, a trend that is consistent over time (data not shown). In addition, both women's and men's perceptions in 2013 are similar to previous years (data not shown). Figure 9. Perceptions v.

Indirect Consequences The data regarding students experiencing consequences as a result of other students drinking are presented in Table 2. These questions were asked of students who drink and students who do not. These questions have been used in drinking surveys going back to 2003, and data from 2006, 2008, and 2011 are provided for comparison points. 57.5% of students reported having had to baby-sit a student who drank too much and similar numbers (55.7%) had their studying or sleep interrupted during this academic year. 32.1% had been insulted or humiliated, and 24.0% had had a serious argument or quarrel as a result of someone else s drinking during this academic year. From 2003 (not shown) to 2006, there was a general upward trend in negative indirect consequences. Those consequences peaked in 2006 and 2008 and since that time have declined (Table 2). Table 2. Percentages of Students Experiencing Indirect Consequences from Other Students Drinking Indirect Consequences 2006 (%) 2008 (%) 2011 (%) 2013 (%) Had to baby-sit a student who drank too much 64.0 65.7 62.7 57.5 Had your studying or sleep interrupted 70.5 66.0 59.7 55.7 Been insulted or humiliated 36.9 40.6 36.4 32.1 Had a serious argument or quarrel 44.5 38.6 30.9 24.0 Had your property damaged 31.4 21.9 17.0 17.9 Been pushed, hit, or assaulted 20.1 17.7 14.0 12.4 Been a victim of unwanted sexual experience 5.8 5.5 6.2 6.3 Direct Consequences All student participants reported on a variety of physical, academic, interpersonal, legal, and sexual consequences they experienced as a result of their own drinking during the current academic year 2. 60.4% reported having had a hangover or headache the morning after drinking, similar to the level in 2011 (60.5%) and lower than in 2008 (68.1%) (Table 3). Just less than half reported having felt sick to their stomach or thrown up (47.3%) and being unable to remember part of the previous evening (46.4%) (Table 3). 22.8% reported missing a class because of their alcohol use, compared to 25.2% in 2011 (Table 3). 31.0% reported doing something they later regretted, compared to 29.8% in 2011 (Table 3). Table 3. Percentages of Students Experiencing Physical, Academic & Interpersonal Consequences from Drinking Direct Consequences: Physical 2008 (%) 2011 (%) 2013 (%) Had a hangover/headache the morning after drinking 68.1 60.5 60.4 Felt sick to your stomach or thrown up 49.3 45.1 47.3 Been unable to remember a part of the previous evening 48.1 43.0 46.4 Been hurt or injured 14.6 12.3 15.8 Gotten into a physical fight 7.3 5.8 4.9 Direct Consequences: Academic Missed class 32.4 25.2 22.8 Gotten behind in school work 26.4 22.0 18.2 Had difficulty concentrating in class 24.2 19.8 15.5 Performed poorly on an assignment or test 15.6 12.6 10.9 Direct Consequences: Interpersonal Done something you later regretted 37.1 29.8 31.0 Become rude, obnoxious, or insulting 36.5 28.5 25.3 Felt guilty about your drinking 28.4 22.8 22.3 2 These percentages represent all respondents. In several cases, the questions asked were also asked in previous surveys on student drinking. Comparison data are available. 6
In addition, 4.6% indicated they had driven under the influence, a substantial decrease from 2008 (Table 4). 4.1% reported having damaged property or set off a false alarm (Table 4). Moreover, 7.1% reported having had sex when they didn t really want to, and 2.7% had been pressured or forced to have sex with someone when they had been too drunk to prevent it (Table 4). Lastly, and similar to findings from previous years, students who engaged in high-risk drinking were significantly more likely to experience all of the consequences when compared to non-high-risk drinkers. Frequent high-risk drinkers were at the greatest risk (analysis not shown). Table 4. Percentages of Students Experiencing Legal & Sexual Consequences from Drinking Direct Consequences: Legal (%) (%) (%) Driven under the influence 7.4 4.7 4.6 Damaged property or set off a false alarm 6.3 4.5 4.1 Gotten in trouble at school 5.9 4.4 3.5 Gotten in trouble with the police 5.3 4.3 2.5 Direct Consequences: Sexual Had sex when you didn t really want to 9.3 8.0 7.1 Been pressured or forced to have sex with someone when you were too drunk to prevent it 3.2 3.1 2.7 Pressured or forced someone to have sex with you after you had been drinking 2.6 1.9 1.4 Protective and Risk Behaviors Another section of the survey included questions regarding protective and risk behaviors when drinking alcohol. The following findings represent only students who drink. The percentages are for those students who indicated they usually or always engage in these behaviors. More responsible drinking is associated with a higher percentage and with a higher average score. With the exceptions of students intentionally eating food before drinking (74.0% usually or always ) and keeping track of how many drinks they have had (53.4%), most students do not frequently practice protective behaviors that will reduce their risks related to alcohol (Table 5). For example, typically students rarely or sometimes (based on the average scores) alternate drinking alcoholic drinks with non-alcoholic beverages, pace their drinking to no more than one drink per hour, think about their BAC to reduce risks, or intentionally mix their drinks with less alcohol than normal (Table 5). In general, the percentages of students practicing protective behaviors increased from 2008 to 2011 (not shown), suggesting that educational efforts are having an impact, but have plateaued somewhat since 2011. Table 5. Protective Behaviors When Drinking (Drinkers Only) Behavior % Usually or Always Average* 2011 2013 2011 2013 Intentionally eat food or a meal before drinking 68.0 74.0 3.73 3.89 Keep track of how many drinks you ve had 56.1 53.4 3.44 3.43 Set a personal limit of how many drinks you ll have during a drinking occasion 34.4 33.0 2.84 2.83 Alternate alcoholic drinks with water or other nonalcoholic beverages 21.9 23.3 2.54 2.62 Pace your drinking to no more than one drink per hour 21.8 18.8 2.45 2.42 Think about your BAC in order to reduce risks associated with alcohol consumption 18.6 17.9 2.20 2.21 Intentionally mix your drinks with less alcohol than normal 15.8 16.5 2.44 2.48 * Scale: 1=never, 2=rarely, 3=sometimes, 4=usually, 5=always. The higher the average the more frequently students are engaging in drinking behaviors that will reduce their risk. 7
In Table 6, data related to risk behaviors associated with alcohol consumption are provided. The percentages are for those students who indicated they rarely or never engage in these behaviors. More responsible drinking is associated with a higher percentage. The opposite is true for the average scores; the lower average is associated with more responsible drinking behavior. Of students who drink, 66.1% reported that they rarely or never chug alcohol, and 38.2% seldom choose a drink containing a higher alcohol concentration. However, only 24.6% reported the same when asked about playing drinking games, indicating that playing drinking games is the most common risk behavior among drinkers. In addition, only 27.6% of students who drink are unlikely to pre-game, and only 26.8% are unlikely to do shots. These percentages demonstrate an increase in risk behaviors since 2011. Table 6. Risk Behaviors When Drinking (Drinkers Only) Behavior % Never or Rarely Average* 2011 2013 2011 2013 Chug alcohol (e.g., keg stands, beer funnels) 68.5 66.1 1.98 2.09 Choose a drink containing a higher alcohol concentration 44.3 38.2 2.52 2.71 Pre-game (start drinking before going out) 37.1 27.6 2.99 3.26 Do shots 31.5 26.8 3.00 3.18 Play drinking games 28.7 24.6 3.04 3.18 * Scale: 1=never, 2=rarely, 3=sometimes, 4=usually, 5=always. The lower the average, the more frequently students are engaging in drinking behaviors that will reduce their risk
