Screening and brief intervention for high-risk college student drinkers: results from a 2-year follow-up assessment

This randomized controlled trial evaluated the efficacy of a brief intervention designed to reduce the harmful consequences of heavy drinking among high-risk college students. Students screened for risk while in their senior year of high school (188 women and 160 men) were randomly assigned to receive an individualized motivational brief intervention in their freshman year of college or to a no-treatment control condition. A normative group selected from the entire screening pool provided a natural history comparison. Follow-up assessments over a 2-year period showed significant reductions in both drinking rates and harmful consequences, favoring students receiving the intervention. Although high-risk students continued to experience more alcohol problems than the natural history comparison group over the 2-year period, most showed a decline in problems over time, suggesting a developmental maturational effect.

Targeting misperceptions of descriptive drinking norms: efficacy of a computer-delivered personalized normative feedback intervention.

The authors evaluated the efficacy of a computer-delivered personalized normative feedback intervention in reducing alcohol consumption among heavy-drinking college students. Participants included 252 students who were randomly assigned to an intervention or control group following a baseline assessment. Immediately after completing measures of reasons for drinking, perceived norms, and drinking behavior, participants in the intervention condition were provided with computerized information detailing their own drinking behavior, their perceptions of typical student drinking, and actual typical student drinking. Results indicated that normative feedback was effective in changing perceived norms and alcohol consumption at 3- and 6-month follow-up assessments. In addition, the intervention was somewhat more effective at 3-month follow-up among participants who drank more for social reasons.

Mindfulness-Based Relapse Prevention for Substance Use Disorders: A Pilot Efficacy Trial

ABSTRACT The current study is the first randomized-controlled trial evaluating the feasibility and initial efficacy of an 8-week outpatient Mindfulness-Based Relapse Prevention (MBRP) program as compared to treatment as usual (TAU). Participants were 168 adults with substance use disorders who had recently completed intensive inpatient or outpatient treatment. Assessments were administered pre-intervention, post-intervention, and 2 and 4 months post-intervention. Feasibility of MBRP was demonstrated by consistent homework compliance, attendance, and participant satisfaction. Initial efficacy was supported by significantly lower rates of substance use in those who received MBRP as compared to those in TAU over the 4-month post-intervention period. Additionally, MBRP participants demonstrated greater decreases in craving, and increases in acceptance and acting with awareness as compared to TAU. Results from this initial trial support the feasibility and initial efficacy of MBRP as an aftercare approach for individuals who have recently completed an intensive treatment for substance use disorders.

Mindfulness meditation and substance use in an incarcerated population

Despite the availability of various substance abuse treatments, alcohol and drug misuse and related negative consequences remain prevalent. Vipassana meditation (VM), a Buddhist mindfulness-based practice, provides an alternative for individuals who do not wish to attend or have not succeeded with traditional addiction treatments. In this study, the authors evaluated the effectiveness of a VM course on substance use and psychosocial outcomes in an incarcerated population. Results indicate that after release from jail, participants in the VM course, as compared with those in a treatment-as-usual control condition, showed significant reductions in alcohol, marijuana, and crack cocaine use. VM participants showed decreases in alcohol-related problems and psychiatric symptoms as well as increases in positive psychosocial outcomes. The utility of mindfulness-based treatments for substance use is discussed.

Male and Female Recipients of Unwanted Sexual Contact in a College Student Sample: Prevalence Rates, Alcohol Use, and Depression Symptoms

It is typically assumed that acquaintance rapeand other forms of unwanted sexual contact involve malesas perpetrators and females as victims. The currentstudyinvestigated prevalence rates of experiencing as well as instigating sexual coercion, force,and other types of unwanted sexual contact for both menand women in a college Greek system. 165 men and 131women (82% Caucasian) completed 2 gender neutral measures of unwanted sexual contact, as well asassessments of alcohol use, alcohol related negativeconsequences, and depressive symptoms. Results indicatedmen were as likely to report being the recipients of sexual coercion as were women in thissample, although women were more likely to be thevictims of physical force. In addition, both men andwomen in this sample who had been the recipientsofunwanted sexual contactreported heavier alcoholconsumption and related negative consequences than didtheir peers who had nothad these experiences. Men whohad been the recipients of unwanted sexual contactreported more symptoms of depression than other men inthis sample, but there were no differences in depressionsymptoms for women who did or did not report theseexperiences.

Exploring College Student Gambling Motivation

The present research combined qualitative and quantitative approaches in examining gambling motives among college student gamblers. A comprehensive set of 16 gambling motives was identified by categorizing 762 open-ended reasons for gambling, provided by 184 college student gamblers. Results revealed that most college students gamble to win money, for fun, for social reasons, for excitement, or just to have something to do. Overall, the results suggest the need for an eclectic biopsychosocial approach with regard to etiology of college student gambling.

Personalized mailed feedback for college drinking prevention: a randomized clinical trial

The current study was designed to evaluate the efficacy of a mailed feedback and tips intervention as a universal prevention strategy for college drinking. Participants (N = 1,488) were randomly assigned to feedback or assessment-only control conditions. Results indicated that the mailed feedback intervention had a preventive effect on drinking rates overall, with participants in the feedback condition consuming less alcohol at follow-up in comparison with controls. In addition, abstainers in the feedback condition were twice as likely to remain abstinent from alcohol at follow-up in comparison with control participants (odds ratio = 2.02), and feedback participants were significantly more likely to refrain from heavy episodic drinking (odds ratio = 1.43). Neither gender nor severity of baseline drinking moderated the efficacy of the intervention in these analyses, but more conservative analyses utilizing last-observation carryforward suggested women and abstainers benefited more from this prevention approach. Protective behaviors mediated intervention efficacy, with participants who received the intervention being more likely to use strategies such as setting limits and alternating alcohol with nonalcoholic beverages. Implications of these findings for universal prevention of college drinking are discussed.

Being Controlled by Normative Influences: Self-Determination as a Moderator of a Normative Feedback Alcohol Intervention

The objectives of this research were to evaluate the efficacy of computer-delivered personalized normative feedback among heavy drinking college students and to evaluate controlled orientation as a moderator of intervention efficacy. Participants (N = 217) included primarily freshman and sophomore, heavy drinking students who were randomly assigned to receive or not to receive personalized normative feedback immediately following baseline assessment. Perceived norms, number of drinks per week, and alcohol-related problems were the main outcome measures. Controlled orientation was specified as a moderator. At 2-month follow-up, students who received normative feedback reported drinking fewer drinks per week than did students who did not receive feedback, and this reduction was mediated by changes in perceived norms. The intervention also reduced alcohol-related negative consequences among students who were higher in controlled orientation. These results provide further support for computer-delivered personalized normative feedback as an empirically supported brief intervention for heavy drinking college students, and they enhance the understanding of why and for whom normative feedback is effective.

Normative misperception and the impact of descriptive and injunctive norms on college student gambling.

Two studies examined college student gambling as a function of descriptive and injunctive social norms. It was expected that individuals would overestimate the descriptive norm and that both descriptive and injunctive norms would uniquely predict gambling behavior and problem gambling. In Study 1, self-reported gambling frequency among 317 college students was found to be lower than perceived typical college student gambling behavior. Study 2, which included 560 college students, replicated the results of Study 1 and revealed similar findings with respect to perceived and actual descriptive norms for gambling expenditure. Perceived descriptive and injunctive norms uniquely predicted self-reported gambling frequency, expenditure, and negative consequences related to gambling. The utilization of social norms-based interventions to reduce problem gambling among college students is discussed.

Heavy drinking in college students: who is at risk and what is being done about it?

Problem drinking and related consequences are a major social issue plaguing college campuses across the United States. Each year, alcohol is responsible for fatalities, assaults, serious injuries, and arrests that occur among college students. The authors review and discuss the risk factors, drinking patterns, and consequences that are relevant to the general student population. In addition, the authors highlight individuals at an increased risk of experiencing alcohol-related problems, such as Greek-letter social organization members and student athletes. The authors also discuss the interventions that attempt to reduce risky drinking and related problems in these subgroups as well as the future directions for research.
