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.

Interventions to reduce harm associated with adolescent substance use

A major proportion of the disease burden and deaths for young people in developed nations is attributable to misuse of alcohol and illicit drugs. Patterns of substance use established in adolescence are quite stable and predict chronic patterns of use, mortality, and morbidity later in life. We integrated findings of systematic reviews to summarise evidence for interventions aimed at prevention and reduction of harms related to adolescent substance use. Evidence of efficacy was available for developmental prevention interventions that aim to prevent onset of harmful patterns in settings such as vulnerable families, schools, and communities, and universal strategies to reduce attractiveness of substance use. Regulatory interventions aim to increase perceived costs and reduce availability and accessibility of substances. Increasing price, restricting settings of use, and raising legal purchase age are effective in reducing use of alcohol and tobacco and related harms. Screening and brief intervention are efficacious, but efficacy of a range of treatment approaches has not been reliably established. Harm-reduction interventions are effective in young people involved in risky and injecting substance use.

Gender-Specific Misperceptions of College Student Drinking Norms

This study evaluated perceptions of same-sex and opposite-sex gender-specific versus gender-nonspecific drinking norms among college students (115 men, 111 women). This research is consistent with previous findings that college students overestimate the quantity and frequency of drinking among their gender-nonspecific peers and demonstrates that both men and women overestimate the quantity and frequency of the drinking of their same-sex peers. The findings suggest that perceived same-sex norms are more strongly associated with problematic drinking than are gender-nonspecific norms and that perceived same-sex drinking norms are stronger predictors of alcohol consumption for women than for men. Results suggest that interventions incorporating normative feedback should be framed differently for women than for men.

Social Norms Approaches Using Descriptive Drinking Norms Education: A Review of the Research on Personalized Normative Feedback.

College students have been shown to consistently overestimate the drinking of their peers. As a result, social norms approaches are effective in correcting these misperceived norms to reduce alcohol consumption and alcohol-related problems. In this review of literature, the authors critically evaluated the effectiveness of personalized normative feedback. In addition, the authors reviewed personalized normative feedback interventions and provided suggestions for increasing the efficacy of these interventions by making better use of salient referent group data.

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.

The relative impact of injunctive norms on college student drinking: the role of reference group.

This research evaluated the importance of reference groups in the relationships between injunctive norms and alcohol consumption for college student drinkers. First-year students (N = 811; 58% women) completed online assessments of their drinking behavior, as well as their perceptions of the approval (injunctive norms) and prevalence (descriptive norms) of drinking by others. Injunctive norms were evaluated with respect to typical students, typical same-sex students, friends, and parents. Descriptive norms were evaluated with respect to typical students and typical same-sex students. Results suggested that for injunctive norms, only perceptions of proximal reference groups (friends and parents) are positively associated with drinking behavior. However, when considered in the context of multiple referents and norms, injunctive norms for more distal groups (typical students/same-sex students) were negatively associated with personal drinking, whereas descriptive norms for distal referents remained positively associated with drinking. Results suggest that injunctive norms are more complex than descriptive norms and these complexities warrant important consideration in the development of intervention strategies.

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.

Appearance-Related Social Comparisons: The Role of Contingent Self-Esteem and Self-Perceptions of Attractiveness

Two studies examined contingent self-esteem (CSE) and responses to appearance-related social comparisons. Study 1 was an experimental study in which women rated a series of advertisements from popular women’s magazines. Study 2 employed an event-contingent diary recording procedure. In Study 1, women who were higher in CSE and lower in self-perceptions of attractiveness (SPA) experienced greater decreases in positive affect and greater increases in negative affect following the ad-rating task. Study 2 results supported a mediation model in which women who were higher in CSE felt worse after social comparisons because they made primarily upward comparisons. Overall, results suggest that appearance-related comparisons are more distressing for those who base their self-worth on contingencies and have lower self-perceived attractiveness.
