Addressing Inconsistencies in the Social Norms Drinking Literature: Development of the Injunctive Norms Drinking and Abstaining Behaviors Questionnaire

A novel approach to assess descriptive and injunctive norms for college student marijuana use

Descriptive and injunctive norms are traditionally assessed using different metrics. Following an innovation in the alcohol field, we examined a novel measure of perceived descriptive and injunctive marijuana norms (i.e., Marijuana Norms Grid, MNG) to characterize how these normative perceptions relate to one's own use of marijuana. The present study addressed three research questions: (1) Do college students overestimate descriptive/injunctive marijuana norms of typical college students and close friends? (2) Are descriptive/injunctive norms uniquely related to marijuana frequency and quantity? (3) Are injunctive norms related to marijuana frequency and quantity above and beyond how injunctive norms are traditionally assessed? College students (n = 7000) were recruited from 9 universities throughout the US, including 2077 past month marijuana users. Participants completed an online, cross-sectional survey that included measures assessing marijuana use, marijuana consequences, and descriptive and injunctive marijuana norms using traditional and novel assessments, among other assessments. The results revealed robust self-other discrepancies using the MNG such that participants overestimated how often and how much college students use marijuana. We also found that both descriptive and injunctive norms related uniquely to one's own marijuana use. The MNG injunctive norms explained about 19% of additional variability in marijuana outcomes beyond injunctive norms assessed using the traditional method. The findings of the present study support the utility of the novel assessment of injunctive marijuana norms. Implications for norms-based interventions are discussed.

Understanding perceived usefulness and actual use of protective behavioral strategies: The role of perceived norms for the reasons that young adult drinkers use protective behavioral strategies

INTRODUCTION

The current study examines the norms-behavior link by investigating a novel cognition for protective behavioral strategies (PBS)-descriptive and injunctive norms for close friends' reasons to use PBS (e.g., limit drinking, reduce consequences)-in relation to one's own perception of usefulness and personal use of PBS. Further, we tested whether the association between perceived norms for reasons to use PBS and personal PBS use was mediated by perceived usefulness of PBS.

METHODS

College student drinkers ages 18-24 [N = 301; 53% female, 69% White, mean age = 20.16 years (SD = 1.54)] were recruited for a larger study. Eligible students reported alcohol use 2+ days a week and 1+ occasions of heavy episodic drinking in the last two weeks. Linear regression tested whether descriptive and injunctive norms for reasons to use PBS were associated with perceived usefulness and personal use of PBS; path analysis was used to test mediation. All analyses were conducted by PBS subscale (limiting/stopping, serious harm reduction, manner of drinking).

RESULTS

Descriptive norms for reasons to use PBS (i.e., perceptions that close friends use PBS to reduce drinking/consequences) were positively associated with perceived usefulness and personal PBS use for limiting/stopping and to some extent manner of drinking. For each subscale, the association between descriptive norms for reasons to use PBS and personal PBS use was mediated by perceived usefulness of PBS. Results were not significant for injunctive norms.

CONCLUSIONS

Findings suggest descriptive norms, rather than injunctive norms, for close friends' reasons to use PBS, may be relevant for inclusion in brief interventions.

Drinking, smoking and type a polydrug behaviours: Psychosocial factors among Portuguese university students

Aim

This paper aims to describe alcohol, tobacco and type A polydrug consumption among university students.

Method

A cross-sectional study was performed. Through a convenience sampling, a total of 338 were included (51.8% male with a mean age of 20.6 years, SD = 3.4). Data was collected using a self-reported questionnaire. The questionnaire was composed by sociodemographic and substance consumption and behaviours variables. Spearman's correlation coefficients were assessed to measure the strength and direction of the association between sociodemographic and substance consumption variables. To evaluate type A polydrug consumption, multivariate logistic regression models were performed.

Results

It was observed significant correlations between tobacco consumption with cannabis and alcohol involvement, and coping, conformity, social, enhancement drinking motives. About alcohol consumption, there were observed relations with students’ social environment, and with enhancement, conformity and social drinking motives. Regarding sociodemographic factors on type A polydrug consumption it was verified that students who have parents and friends who smoke are more likely to polydrug.

Conclusion

Findings suggest that interventions focused on substance consumption may need to address descriptive and injunctive norms, drinking motives and social environment as part of the student’s consumption behaviours.

Adolescent Social Norms and Alcohol Use: Separating Between- and Within-Person Associations to Test Reciprocal Determinism

Despite perceived drinking norms being robust predictors of adolescent alcohol use, few studies have assessed the development of perceived norms across adolescence and processes accounting for the strong associations between perceived norms and drinking. Using reciprocal determinism as a theoretical basis for understanding the development of adolescent drinking norms, this study examined reciprocal associations across nine waves of data spanning early to late adolescence. Bivariate latent curve models with structured residuals demonstrated consistent within-person reciprocal associations between descriptive and injunctive norms and alcohol use after accounting for growth in norms and alcohol use. Results suggest the need for developmentally informed intervention efforts targeting perceived drinking norms during early and middle adolescence.

Predicting College Student Drinking and Smoking Intentions With Cognitively Accessible Attitudes and Norms

Understanding the factors that make college students more likely to drink alcohol and smoke cigarettes is key to developing effective interventions in order to reduce these behaviors. This study sought to understand entering college students' intentions to engage in smoking and drinking behavior by examining the cognitive accessibility (ease of retrieval from memory) of attitudes and norms for drinking. A sample of 413 first-year college students living in on-campus residence halls participated in the study in the first 2 weeks of their first semester of college. Reaction time measures of attitudes and norms assessed the cognitive accessibility of these constructs. Hierarchical linear regression analysis was conducted. Results indicated that the cognitive accessibility of both attitudes and peer injunctive norms predicted behavioral intentions to drink and smoke. Our findings indicate that when injunctive peer norms are accessible from memory, they are better predictors of drinking and smoking intentions than descriptive norms or injunctive family norms. Our work provides important guidance for interventions to reduce risky behavior in college students and suggests that emphasizing social costs of these behaviors may be a promising strategy.

Social discomfort moderates the relationship between drinking in response to negative affect and solitary drinking in underage drinkers

OBJECTIVE

Research shows that solitary drinking is associated with negative reinforcement motives (i.e., relieving negative affect). An untested hypothesis proposes that this association may be especially strong for individuals who experience social discomfort. This study aimed to 1) replicate findings linking solitary drinking to social discomfort (i.e., loneliness, social anxiety, and lack of perceived social support), alcohol problems, and drinking in response to negative affect (i.e., drinking to cope motives and inability to resist alcohol during negative affect), and 2) investigate whether greater social discomfort moderates the relationship between drinking in response to negative affect and solitary drinking in underage drinkers.

METHOD

Current alcohol drinkers ages 18 to 20 (N=664) recruited from a TurkPrime panel reported the percentage of time they drank solitarily and completed measures assessing social discomfort, drinking in response to negative affect, and alcohol involvement. Structural equation modeling was used to test the moderation model.

RESULTS

Results replicated prior literature supporting the first aim. For the second aim, analyses indicated a positive association between solitary drinking and drinking in response to negative affect across all individuals, but contrary to prediction, this relationship was stronger for individuals with lower, rather than higher, social discomfort.

CONCLUSION

Underage drinkers with lower, rather than higher, social discomfort appear to be at greater risk for drinking alone. These findings may inform our understanding of individuals at greatest risk for drinking alone and promote new avenues for intervention.
