Evaluation of a single-session expectancy challenge intervention to reduce alcohol use among college students.

In this study, the authors developed and evaluated a single-session experiential expectancy challenge (EC) intervention, seeking to reduce alcohol use by changing key positive expectancies among moderate to heavy drinking male and female college students. Participants (N=217) were randomly assigned to attend a 90- to 120-min EC session, CD-ROM alcohol education, or assessment only. Participants were assessed at pretest, posttest, and 1-month follow-up. Exposure to the EC intervention led to significant decreases in alcohol expectancies and subsequent alcohol consumption in both genders at follow-up. No significant changes were evident in either control condition. This study is the first to effectively decrease expectancies and drinking in college students with a single-session EC intervention. Further, although several studies have demonstrated the utility of the intervention with men, it is the first to do so with women. This study represents a critical step in the process of translating an innovative, theory-based intervention into a more practical format that makes it more accessible to those who seek effective drinking-reduction strategies for college campuses.

Food, mood, and attitude: Reducing risk for eating disorders in college women.

Food, Mood, and Attitude (FMA) is a CD-ROM prevention program developed to decrease risk for eating disorders in college women. Female 1st-year students (N = 240) were randomly assigned to the intervention (FMA) or control group. Equal numbers of students at risk and of low risk for developing an eating disorder were assigned to each condition. Participants in the FMA condition improved on all measures relative to controls. Significant 3-way interactions (Time × Condition × Risk Status) were found on measures of internalization of sociocultural attitudes about thinness, shape concerns, and weight concerns, indicating that at-risk participants in the intervention group improved to a greater extent than did low-risk participants. At follow-up, significantly fewer women in the FMA group reported overeating and excessive exercise relative to controls. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Two brief alcohol interventions for mandated college students.

Encouraging but limited research indicates that brief motivational interventions may be an effective way to reduce heavy episodic drinking in college students. At 2 campuses, students (83% male) mandated to a substance use prevention program were randomly assigned to 1 of 2 individually administered conditions: (a) a brief motivational interview (BMI; n = 34) or (b) an alcohol education session (AE; n = 30). Students in the BMI condition reported fewer alcohol-related problems than the AE students at 3-and 6-month assessments. Trends toward reductions in number of binge drinking episodes and typical blood alcohol levels were seen in both groups. Process measures confirmed the integrity of both interventions. The findings demonstrate that mandated BMIs can reduce alcohol problems in students referred for alcohol violations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Lowering risk for early alcohol use by challenging alcohol expectancies in elementary school children.

Altering alcohol expectancies has reduced alcohol use among young adults and may lead to successful prevention of early alcohol use. The authors randomly assigned 216 4th-grade children to an expectancy challenge or control condition and used individual-differences scaling to map expectancies into memory network format, with preference mapping to model likely paths of association. After expectancy intervention, children exhibited a greater likelihood to associate alcohol use with negative and sedating consequences and a decreased likelihood to associate alcohol with positive and arousing consequences. Children and adults who emphasize negative and sedating effects have been found to be less likely to use alcohol. Therefore, expectancy challenge interventions that have been successful at modifying expectancies and subsequently decreasing alcohol consumption of adults may be useful in reducing the likelihood of early alcohol use among children.

A randomized motivational enhancement prevention group reduces drinking and alcohol consequences in first-year college women.

Alcohol consumption among college students has become an increasing problem that requires attention from college administrators, staff, and researchers. Despite the physiological differences between men and women, college women are drinking at increasingly risky rates, placing them at increased risk for negative consequences. The current study tested a group motivational enhancement approach to the prevention of heavy drinking among 1st-year college women. Using a randomized design, the authors assigned participants either to a group that received a single-session motivational enhancement intervention to reduce risky drinking that focused partly on women's specific reasons for drinking (n = 126) or to an assessment-only control group (n =94). Results indicated that, relative to the control group participants, intervention participants drank fewer drinks per week, drank fewer drinks at peak consumption events, and had fewer alcohol-related consequences over a 10-week follow-up. Further, the intervention, which targeted women's reasons for drinking, was more effective in reducing consumption for participants with high social and enhancement motivations for drinking.

An alcohol treatment program for college students: Community model of inclusion in the university setting.

Students struggling with alcohol problems continue to be part of the college experience. A community model of inclusion consisting of the components of embeddedness, interdependence, intradependence, and evolution (CMEIIE) was used to conceptualize an alcohol treatment program that encourages campus agencies to share resources, training, and ideas. The use of CMEIIE allows universities flexibility to design their own community model of intervention that takes into account (a) current policies, programming, and services; (b) relationships between offices; (c) extensiveness of mental health services; (d) resources of local community agencies; and (e) continual evaluation of the effectiveness of their intervention programs.

Thinking about drinking: Need for cognition and readiness to change moderate the effects of brief alcohol interventions.

Research has demonstrated the efficacy of brief motivational interventions (BMI) and alcohol expectancy challenge (AEC) in reducing alcohol use and/or problems among college students. However, little is known about variables that may qualify the effectiveness of these approaches. The present analyses tested the hypothesis that need for cognition (NFC), impulsivity/sensation seeking (IMPSS) and readiness to change (RTC) would moderate the effects of BMI and AEC. Participants (N = 335) were heavy drinking college students enrolled in a randomized 2 × 2 factorial study of BMI and AEC. Latent growth curve analyses indicated significant interactions for BMI × NFC and AEC × RTC on alcohol use but not problems. Simple slopes analyses were used to probe these relationships and revealed that higher levels of NFC at baseline were associated with a stronger BMI effect on drinking outcomes over time. Similarly, higher levels of baseline RTC were associated with stronger AEC effects on alcohol use. Future preventive interventions with this population may profit by considering individual differences and targeting approaches accordingly.

Factors influencing the temporal relationship between alcohol consumption and experiences with aggression among college women.

The authors assessed temporal relationships among alcohol use, aggression, and mood using daily data from 179 college women. Participants called an interactive voice response system over an 8-week period. The odds of experiencing verbal, sexual, and physical aggression (odd ratios = 2.25, 19.44, and 11.84, respectively) were significantly higher on heavy drinking days (M = 7.46 drinks) compared to nondrinking days. Both a history of victimization and greater psychological symptom severity influenced the odds of involvement in verbal aggression. The odds of alcohol consumption were 3 times higher during the 24 hr following verbal aggression compared with days in which verbal aggression did not occur. On the day immediately following involvement in either verbal or physical aggression, positive mood decreased and negative mood increased. During the week (2-7 days) following sexual aggression, women's positive mood was decreased. These findings reinforce the need for interventions aimed at reducing heavy episodic drinking on college campuses. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Group-based motivational interviewing for alcohol use among college students: An exploratory study.

How can practicing psychologists help reduce excessive alcohol consumption among college students? Over 80% of college students consume alcohol, and a significant percentage drinks excessively with myriad problems. Brief interventions based on motivational interviewing (MI) have been identified for use with college populations. The authors randomly assigned 91 freshman students to a brief, classroom-based MI intervention or an assessment control condition. At the end of the semester, MI group participants reported fewer drinks per occasion and fewer episodes of intoxication compared to controls. A classroom-based, MI-style intervention might be an efficient, sustainable, and effective means of reducing heavy drinking among college students.

Preventing adolescent depression: An evaluation of the Problem Solving For Life program.

This study evaluated the effectiveness of the Problem Solving For Life program as a universal approach to the prevention of adolescent depression. Short-term results indicated that participants with initially elevated depressions scores (high risk) who received the intervention showed a significantly greater decrease in depressive symptoms and increase in life problem-solving scores from pre- to postintervention compared with a high-risk control group. Low-risk participants who received the intervention reported a small but significant decrease in depression scores over the intervention period, whereas the low-risk controls reported an increase in depression scores. The low-risk group reported a significantly greater increase in problem-solving scores over the intervention period compared with low-risk controls. These results were not maintained, however, at 12-month follow-up. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Measured alcohol content in college party mixed drinks.

The main objective of this study was to measure the alcohol content in college party drinks. Samples of mixed drinks were collected from on-campus parties (N = 23) over a 12-week period at a university in the Northeast. Samples were analyzed by using a method that measures oxygen utilization during ethanol oxidation. Standard drink equivalents were calculated and blood alcohol concentrations (BACs) for men and women were estimated. The percent alcohol in sampled drinks ranged from 3.7% to 22.8%. Characteristics of the sampled parties were not related to drink concentration. A party drink at the median concentration and drink size contained 0.97 standard drinks. Estimated BACs varied widely depending on drink alcohol concentration, but in most cases a heavy drinking episode for both men and women resulted in an estimated BAC at or above .08. Mixed drinks at the sampled parties on average approximated one standard drink, but the variability in mixed drink strength compromises a drinker's ability to keep track of the number of drinks consumed.

Relative reinforcing efficacy of alcohol among college student drinkers.

The construct of relative reinforcing efficacy (RRE) is central to many laboratory and theoretical models of drug abuse, but it has not been widely measured in applied clinical research contexts. The authors used a simulated alcohol purchase task to measure RRE in a sample of 267 college student drinkers. Participants reported their alcohol consumption across a range of prices, and their responses were well-described by a regression equation that has been used to construct demand curves in drug self-administration studies. Several measures of relative reinforcing efficacy were generated, including breakpoint, intensity of demand, elasticity, Pmax (price at which response output is maximized), and Omax (maximum alcohol expenditures). Demand for alcohol was inelastic across the initial range of prices but became elastic as price increased. Students who reported recent heavy drinking reported significantly greater intensity of demand, Omax, and breakpoint. These results provide initial support for the validity of the RRE indices generated with the alcohol purchase task. These results also provide empirical support for programs that attempt to reduce alcohol abuse by eliminating low-cost access to alcohol.

Men and women, alcohol and aggression.

The purpose of this study was to examine the acute effects of alcohol on aggressive behavior in men and women in a laboratory setting. Participants were 526 (261 men and 265 women) healthy social drinkers between 21 and 35 years of age. They were randomly assigned to either an alcohol or a placebo group. Aggression was measured using a modified version of the Taylor Aggression Paradigm in which electric shocks are received from, and delivered to, a same gender fictitious opponent during a supposed competitive interpersonal task. Aggression was operationalized as the intensity and duration of shocks that participants administered to their “opponent.” Overall, men were more aggressive than women. Alcohol increased aggression for both men and women but this effect was stronger for men. This is one of the first laboratory studies to demonstrate that alcohol increases aggression in women.

Brief alcohol intervention with college student drinkers: Face-to-face versus computerized feedback.

Research has demonstrated that brief interventions featuring personalized feedback can be used to decrease alcohol use among heavy-drinking college students. The current study investigated the efficacy of face-to-face and computer delivered interventions relative to an assessment-only control condition. The content of the personalized feedback was identical across the face-to-face and computerized conditions. There were 84 at-risk students assessed before, and 4 weeks after, the delivery of the interventions. The results suggest that both face-to-face and computerized interventions were equally successful in reducing the quantity and frequency of alcohol consumption, and that both interventions were more effective than the control condition. Participants also rated both interventions as acceptable, although the face-to-face intervention was given a more favorable rating. These initial results suggest that computerized interventions can be used to efficiently reduce alcohol use among college students. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A program for training college teachers of psychology: Mark II.

Changes in the program for training psychology teachers at the University of Michigan earlier reported (see 26: 59) are discussed. Major sections are: Selection, Training, Initial Experience, Teaching Experience and the Teaching Seminar, and Evaluating the Program. In the teaching seminar, 2 focal points in discussing the role of phychology in a liberal and general education are (a) a list of objectives for introductory psychology prepared by McKeachie and (b) Claude Buxton's book, College Teaching: A Psychologist's View.

An effectiveness trial of a dissonance-based eating disorder prevention program for high-risk adolescent girls.

Efficacy trials indicate that an eating disorder prevention program involving dissonance-inducing activities that decrease thin-ideal internalization reduces risk for current and future eating pathology, yet it is unclear whether this program produces effects under real-world conditions. The present effectiveness trial tested whether this program produced effects when school staff recruit participants and deliver the intervention. Adolescent girls with body image concerns (N = 306; M age = 15.7, SD = 1.1) randomized to the dissonance intervention showed significantly greater decreases in thin-ideal internalization, body dissatisfaction, dieting attempts, and eating disorder symptoms from pretest to posttest than did those assigned to a psychoeducational brochure control condition, with the effects for body dissatisfaction, dieting, and eating disorder symptoms persisting through 1-year follow-up. Effects were slightly smaller than those observed in a prior efficacy trial, suggesting that this program is effective under real-world conditions, but that facilitator selection, training, and supervision could be improved.

Binge drinking among underage college students: A test of a restraint-based conceptualization of risk for alcohol abuse.

The authors tested a restraint-based model that binge drinking is a function of being tempted to drink alcohol while also being concerned about avoiding excessive alcohol intake. Underage (18-to 20-year-olds, 204 men and 225 women) college student drinkers completed measures that assessed the attraction to alcohol (e.g., temptation to drink, alcohol expectancies), concern about regulating alcohol intake (e.g., restriction of alcohol intake, reasons for limiting drinking), and alcohol-related outcomes (binge drinking, alcohol problems). In separate hierarchical multiple regressions, the attraction to alcohol accounted for significant amounts of additional variance in each of the alcohol outcomes. Concern about regulating alcohol intake accounted for additional variance, above that explained by attraction to alcohol. The results suggest that interventions for underage binge drinking should include training in the skills for regulating alcohol intake.

Long-term effects of the strong african american families program on youths’ alcohol use.

Objective:This report extends earlier accounts by addressing the effects of the Strong African American Families (SAAF) program across 65 months. Two hypotheses were tested: (a) Rural African American youths randomly assigned to participate in SAAF would demonstrate lower rates of alcohol use than would control youths more than 5 years later, and (b) SAAF’s effects on deterring the onset of alcohol use in early adolescence would carry forward to mediate the program’s long-term effects. Method: African American youths in rural Georgia (mean age at pretest = 10.8 years) were assigned randomly to the SAAF group (n = 369) or to a control group (n = 298). Past-month alcohol use was assessed at pretest and at 9, 18, 29, 53, and 65 months after pretest. Results: SAAF participants increased their alcohol use at a slower rate than did adolescents in the control condition across the follow-up assessments. At the 65-month assessment, SAAF participants reported having drunk alcohol half as often as did youths in the control group. Consistent with the second hypothesis, SAAF’s effects on deterring initiation carried forward to account for its effects on alcohol use across time. Conclusions: Training in protective parenting processes and self-regulatory skills during preadolescence may contribute to a self-sustaining trajectory of disinterest in and avoidance of alcohol use during adolescence when peers begin to model and sanction it.

Finding common ground for effective campus-based prevention.

This commentary reviews the controversy over use of the term binge drinking to describe college student alcohol consumption, argues for abandoning the term, and explains how doing so will help unify and reinvigorate campus-based prevention work. Binge drinking has been defined for men as 5 or more drinks in a row at least once in the previous 2 weeks and as 4 or more drinks for women. There is no scientific basis for focusing on this measure to the exclusion of other consumption measures; neither is there justification for labeling such consumption binge drinking, which reinforces an exaggerated view of student drinking. To build support for environmental management strategies to reduce alcohol-related problems, campus officials should avoid terminology that demonizes students and instead embrace the responsible majority of college students as an essential part of the solution.

Screening for depression prevention: Identifying adolescent girls at high risk for future depression.

This study investigated a broad array of putative risk factors for the onset of major depression and examined their screening properties in a longitudinal study of 479 adolescent girls. Results indicated that the most potent predictors of major depression onset included subthreshold depressive symptoms, poor school and family functioning, low parental support, bulimic symptoms, and delinquency. Classification tree analysis revealed interactions between 4 of these predictors, suggesting qualitatively different pathways to major depression. Girls with the combination of elevated depressive symptoms and poor school functioning represented the highest risk group, with a 40% incidence of major depression during the ensuing 4-year period. Results suggest that selected and indicated prevention programs should target these high-risk populations and seek to reduce these risk factors.
