Do different types of social identity moderate the association between perceived descriptive norms and drinking among college students?

Descriptive Drinking Norms and Alcohol-Related Negative Consequences: A Moderated Mediation Model Involving Drinking Quantity and Protective Behavioral Strategies

We examined whether drinking quantity mediated the relationship between descriptive drinking norms and alcohol-related negative consequences, and if this was moderated by protective behavioral strategies (PBS) use. Undergraduate students ( n = 538, 78.0% female, mean age = 21.21 [ SD = 3.62]) from three Spanish universities completed a questionnaire. Simple and moderated mediation analyses were conducted. Drinking quantity fully mediated the relationship between descriptive drinking norms and alcohol consequences, and PBS moderated this relationship. Among participants with high PBS use, the impact of descriptive drinking norms on drinking quantity disappeared. The indirect effect of descriptive drinking norms on alcohol consequences through drinking quantity was significant for individuals with low/moderate PBS use levels, but not for those with high PBS use. Our findings shed light on how descriptive drinking norms influence alcohol-related negative consequences, and suggest that promoting the utilization of PBS could be an effective approach to ameliorate the impact of peer influences on drinking behavior.

Human PapillomaVirus vaccination in gay and bi men: Predictors, dynamic norms, and connectedness to the LGBT+ community

OBJECTIVES

This study tested social cognitive predictors of vaccination and a dynamic norms intervention for increasing HPV vaccination intentions in gay, bisexual, and other men who have sex with men (gbMSM).

DESIGN

The study employed an experiment embedded in a cross-sectional survey.

METHODS

Participants (N = 217; gbMSM aged 18-45 in Ireland) provided cross-sectional data on sociodemographic constructs and constructs from the Theory of Planned Behaviour and the Health Belief Model. Unvaccinated participants (n = 94) were randomised to one of three experimental conditions (no norms, static norms, dynamic norms) and presented with information on HPV vaccine uptake in gbMSM in Ireland before reporting vaccination intentions.

RESULTS

In an adjusted logistic regression, significant predictors of vaccination included being in a relationship (OR = 8.69 [1.09, 38.91]), perceived susceptibility (OR = 1.11 [1.04, 1.19]), healthcare provider recommendation (OR = 107.24 [26.87, 427.99]), and perceived barriers (OR = 0.83 [.7, 0.98]). Adjusted linear regression models showed no significant differences in HPV vaccination intentions between no norms and static norms (B = -1.24 [-4.6, 2.12]), dynamic norms and static norms (B = -0.62 [-3.86, 2.63]), and dynamic norms and no norms (B = 0.62 [-2.74, 3.98]). Connectedness to the LGBT+ community did not moderate these differences.

CONCLUSIONS

The need for greater awareness of susceptibility, the impact of barriers, and the strong influence of a recommendation from a healthcare provider in predicting HPV vaccination among gbMSM are critical considerations for policymakers. Dynamic norm messaging may be less effective for vaccination than other behaviours more easily influenced by social norms. Efforts to implement dynamic norm-based interventions in gbMSM should consider the limited evidence of efficacy.

Social identity and health-related behavior: A systematic review and meta-analysis

This paper examined the relationship between social identity and health-related behavior, exploring whether social identities are associated with multiple health-related behaviors or only specific ones, and whether this association varies on the type of social identity, the type of social identity measures or the expected relationship between identity and behavior. In a systematic review and meta-analysis we assessed whether the pattern of findings can be explained by the social identity approach. An extensive literature search was conducted in several databases including EBSCO-host and PubMed, using elaborate search terms related to social identity and health-related behavior. This resulted in 10728 potential articles, with 115 articles (with 248 effect sizes from 133 independent samples, N = 112.112) included in the meta-analysis. We found a small but positive overall association between social identification and health-related behavior, which was present for actual behavior, as well as for intention and attitudes. This association was stronger for health-related social identities, positive health-related behaviors, when the expected relationship was positive and when indirect social identity measures were used. However, not all findings could be explained by the social identity approach, indicating a need for further research to better understand the relationship between social identity and health-related behavior, in order to more effectively incorporate social identity into health interventions.

Normative Perceptions of Peer Drinking Distinguish High-Intensity Drinkers from Other Drinking Groups

Background: High-intensity drinking (HID), or drinking that doubles the binge threshold (i.e., 8+/10+ drinks for women/men), is associated with more negative consequences than binge-only drinking. However, research focusing on HID and factors that may delineate HID from other drinking behaviors is lacking. The present study evaluated if perceived norms for peer drinking behavior (i.e., descriptive norms for alcohol quantity and frequency and injunctive norms) differentiated high-intensity drinkers from other drinker statuses. Further, we evaluated the role of perceived norms on odds of HID engagement and HID frequency. Finally, college status, sex, and underage drinker status were evaluated as moderators of the association between perceived norms and HID status/frequency. Methods: Participants were 623 emerging adult drinkers recruited via Craigslist (68.7% male; 69.0% White). Participants completed an online survey on their drinking behaviors and related social factors. Results: Each domain of perceived norms positively associated with drinker status. Higher perceived norms were associated with greater odds of HID and predicted HID frequency. The association between quantity and frequency descriptive norms and HID engagement was stronger for nonstudents and was only significant for males. Underage drinker status did not moderate associations between perceived norms and HID engagement. Conclusions: Findings provided evidence that perceptions of peer drinking behaviors are strong indicators of HID risk and may be especially useful for identifying high-intensity drinking males and nonstudents. The utility of perceived peer norms to differentiate this group of particularly risky drinkers suggests that social-influence-focused intervention approaches, including norms correction, may be efficacious in targeting HID among emerging adults.

Development and validation of the Personal Assessment of Responsible Drinking Identity (PARDI) with a college student sample

Recent research shows a link between identity and behavior change. Despite the existence of several measures that assess components of drinking identity, no measures examine the idiosyncrasies of a "Responsible Drinking Identity," though responsible drinking is an aim of many alcohol-related interventions. The present study created a measure of responsible drinking identity, the Personal Assessment of Responsible Drinking Identity (PARDI). Two cross-sectional designs and a prospective follow-up were used to develop and assess the psychometric properties of the PARDI. Study 1 used a U.S. national sample of college students who endorsed alcohol use (n = 911) to conduct an Exploratory Factor Analysis. Study 2 consisted of college students from a Southeastern University (n = 1,096) and was used to conduct a Confirmatory Factor Analysis, as well as evaluate convergent, discriminant, concurrent, and incremental validity. A subsample from Study 2 was then assessed after 1 month (n = 194). The follow-up examined test-retest reliability and predictive validity. The PARDI consists of four identity-based factors that are indicative of responsible drinking. The measure had adequate validity across all domains and good test-retest reliability. The measure appears to predict future protective behaviorial strategies (safe drinking behaviors), which mediates the relationship between the PARDI and both future alcohol use and consequences, suggesting safe or responsible drinking identity may drive a key behavioral target of substance use interventions. The PARDI may offer a tool to aid in quantifying underlying constructs of identity and behavior change in substance use interventions. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The reciprocal relationship between social identity and adherence to group norms

Previous research has focused on how social identification influences people's adherence to group norms, but has rarely considered how norm adherence might in turn influence how strongly people identify with the group. We proposed a reciprocal relationship between social identification and norm adherence that is shaped by the salience of the social identity in question. Drawing on data from a longitudinal field study of young people attending a mass gathering (N = 661, 1239 unique observations), we used cross-lagged panel modelling across five timepoints to test the reciprocal relationship between social identification with friends and anticipated adherence to perceived drinking norms among friends before (T0), during (T1-T3), and after (T4) the event. Greater social identification at T1 significantly predicted greater norm adherence at T2 which, in turn, predicted greater social identification at T3. These bidirectional effects were only significant during the mass gathering event, when the referent social identity was salient and thus relevant and meaningful in the social context. Findings indicate a complex interplay between social identity and norm adherence that is context dependent and evolves over time. Not only does social identity promote norm adherence but also adherence to those same norms can reinforce a sense of connection to the group.

Alcohol Protective Behavioral Strategies in Young Spanish Adults in the Community: A Prospective Study of Perceived Efficacy and Social Norms

BACKGROUND

Protective behavioral strategies (PBS) have been shown to be useful for reducing excessive alcohol use and alcohol-related problems. However, research on the explanatory factors of PBS is limited. This paper prospectively examines the contribution of perceived efficacy of PBS in reducing alcohol-related consequences and perceived descriptive norms of close peers´ PBS use in young adults. The mediating role of perceived efficacy of PBS between descriptive norms of PBS use and personal PBS use is also examined.

METHOD

Targeted sampling was used to recruit a community-based sample of 339 young Spanish adults aged 18-25 years, who completed baseline and two-month follow-up questionnaires. Three types of PBS (serious harm reduction-SHR, manner of drinking-MOD, and stopping/limiting drinking-SLD) were measured.

RESULTS

Both perceived efficacy and descriptive norms at baseline were positively associated with personal PBS use (SHR, MOD and SLD) at follow-up. A partial mediation effect of perceived efficacy between descriptive norms and personal PBS use was found for the three PBS subscales.

CONCLUSIONS

Our findings support the usefulness of correcting misperceptions of PBS use by peers in interventions aimed at reducing excessive drinking and alcohol-related consequences in young adults in the community. Moreover, PBS perceived efficacy should be included as a component of these interventions.

Dynamic Norms and Food Choice: Reflections on a Failure of Minority Norm Information to Influence Motivation to Reduce Meat Consumption

Recent research in the US shows the potential of providing information about minority norms that are increasing on positively influencing interest and engagement in desired behaviours. Although these are promising findings, there is little published research replicating or testing this effect outside the US. The study reported here is a direct replication of Sparkman and Walton’s (2017) research. We explored the effects of different kinds of normative information, particularly information about increasing (referred to as ‘dynamic’ or ‘trending’) minority norms, on interest in reducing meat consumption, attitudes toward reducing meat consumption, intentions to reduce meat consumption, and expectations to do so. Following pilot work (n = 197), we used a double-blind online study with three conditions: dynamic norm (n = 276), static norm (n = 284), and no norm (n = 286). The sample consisted of British people, with ages ranging from 18 to 79 (Mage = 37.21, SDage = 13.58; 56.38% female). There was no effect of dynamic norm information on any outcomes, including predictions about future meat consumption norms. Exploratory analyses suggest that political position and gender were associated with meat consumption outcomes. The findings are discussed in relation to conditions under which dynamic normative information may be successful in influencing motivation to engage in desired behaviours, and to possible improvements in research design.

Self in the Service: Self-Identification Moderates the Association between Perceived Drinking Norms and Own Drinking among Veterans

PURPOSE

Drinking is common among young adult veterans. Previous research has established that veterans' drinking is more strongly associated with veteran versus civilian drinking norms. The present research extends these findings by examining the influence of self-identification both with other veterans and with civilians as moderators of the association between perceived norms and drinking.

METHODS

Veterans aged 18-34 (N = 1015; 88.7% male; M = 28.23, SD = 3.44) were recruited via Facebook to participate. Measures included same-gender veterans/same-gender civilians self-identification, same-gender veterans/same gender-civilians perceived drinking norms, and own drinking.

RESULTS

Pairwise comparisons revealed both male and female veterans identified more with other veterans than civilians and perceived drinking to be more prevalent among other veterans than civilians. However, males overestimated male veteran drinking norms to a greater degree than male civilian norms whereas the opposite was true for females. Negative binomial analysis examining a three-way interaction between veteran identification, civilian identification, and civilian norms revealed civilian drinking norms were positively associated with drinking, particularly for veterans who strongly identified with both veterans and civilians. Conversely, civilian drinking norms were also found to be negatively associated with drinking, particularly for those who did not identify strongly with civilians but identified strongly with veterans.

IMPLICATIONS

This study represented a preliminary step for understanding how identity plays a role in terms of veterans' drinking. Given that veterans drank at differing levels of identification, it may be important to consider identities that are most salient when designing interventions targeting individual veterans.

Perceived Substance Use Norms Among Jailed Women with Alcohol Use Disorders

BACKGROUND

Social norms regarding substance use predict substance use behaviors. In a sample of jailed women with alcohol use disorders (AUDs), we compared (i) jailed women's perceptions of the US women population's rates of substance use, with US women's actual rates of substance use; (ii) jailed women's perceived rates of substance use by US women, with their perceptions of use by their own friends; and (iii) US women's actual rates of substance use, with observed sample substance use rates.

METHODS

Participants were 205 jailed women who met criteria for an AUD. We used the 1-sample or dependent-samples t-test to make the comparisons.

RESULTS

Participants overestimated US women's rates of substance use and incarceration rates. They perceived their friends' substance use as less common than US women's. The jailed women reported higher rates of their own substance use than actual rates by US women. In addition, jailed women self-reported less cannabis use, but more alcohol and cocaine use and cigarette smoking, than they perceived their friends to have used. The more women perceived their friends as drinking, the less they had a goal to drink less or abstain from drinking postincarceration; in contrast, perceptions of US women's drinking were not related to personal goals for drinking.

CONCLUSIONS

Interventions that correct misperceptions about substance use norms may have utility for jailed women with AUDs.

Alcohol in TV series popular with teens: a content analysis of TV series in France 22 years after a restrictive law

BACKGROUND

European citizens are the largest alcohol users in the world with an average of 11 l of alcohol per individual per year being used. This consumption practice usually begins during adolescence. Youths' views of substances consumption are built upon socialization experiments from which television takes part. To prevent vulnerable people from media influence, some governments tend to adopt restrictive laws against alcohol marketing within the public space including TV programmes; others rely on the self-control of the alcohol and/or media industry. More than 22 years ago, France adopted a restrictive law made of measures aiming to regulate or prohibit advertising of alcoholic products, especially within media dedicated to minors.

METHODS

This study relies on a content analysis to identify the patterns and the frequencies of occurrences linked to alcohol within a sample of 14 TV series (8 French series and 6 American series) most watched by French teenagers. In total, 180 episodes have been analysed representing 111 h 24 min and 6 s of series coded.

RESULTS

Alcohol is depicted within 87.8% of the sample. French series statistically show more events related to alcohol when compared to the American series. In French series, alcohol, mainly wine, is associated with a familiar lifestyle context with primary characters.

CONCLUSION

The restrictive law ongoing in France does not prevent popular TV programmes watched by minors to depict alcohol. Concerns should be raised about the impact of the values given to the substance integrated to main characters life within the media.

The Normative Underpinnings of Population-Level Alcohol Use: An Individual-Level Simulation Model

Background. By defining what is "normal," appropriate, expected, and unacceptable, social norms shape human behavior. However, the individual-level mechanisms through which social norms impact population-level trends in health-relevant behaviors are not well understood. Aims. To test the ability of social norms mechanisms to predict changes in population-level drinking patterns. Method. An individual-level model was developed to simulate dynamic normative mechanisms and behavioral rules underlying drinking behavior over time. The model encompassed descriptive and injunctive drinking norms and their impact on frequency and quantity of alcohol use. A microsynthesis initialized in 1979 was used as a demographically representative synthetic U.S. population. Three experiments were performed in order to test the modelled normative mechanisms. Results. Overall, the experiments showed limited influence of normative interventions on population-level alcohol use. An increase in the desire to drink led to the most meaningful changes in the population's drinking behavior. The findings of the experiments underline the importance of autonomy, that is, the degree to which an individual is susceptible to normative influence. Conclusion. The model was able to predict theoretically plausible changes in drinking patterns at the population level through the impact of social mechanisms. Future applications of the model could be used to plan norms interventions pertaining to alcohol use as well as other health behaviors.

Demandas laborales y consumo de alcohol: el rol del grupo de trabajo

El objetivo del presente estudio fue determinar si la identificación con grupos de trabajo, con normas desfavorables y favorables de consumo de alcohol del grupo de trabajo, modera la relación entre las demandas del trabajo y el consumo de alcohol en trabajadores. A través de una análisis de regresión, usando la macro de moderación moderada en una muestra de trabajadores de una empresa de telecomunicaciones de Chile (N = 1.143), se presta apoyo a las hipótesis de moderación moderada: la alta identificación con grupos de trabajo con normas desfavorables de consumo de alcohol de ese grupo amortigua la relación entre las demandas del trabajo y el consumo de alcohol en trabajadores (B = -0,080; t = -2,01; p = 0,04; IC95%: -0,1600; -0,0024) y la alta identificación con grupos de trabajo con normas favorables de consumo de alcohol de ese grupo incrementa la relación entre las demandas del trabajo y el consumo de alcohol en trabajadores (B = 0,170; t = 2,36; p = 0,01; IC95%: 0,030; 0,322). Estos resultados sugieren que la alta identificación con grupos de trabajo y sus normas sociales de consumo de alcohol son recursos laborales que, de manera conjunta, pueden afectar o proteger a trabajadores expuestos a altas demandas laborales. Por lo tanto, se recomienda atender a los potenciales efectos positivos, así como también a los efectos perniciosos, de estos recursos laborales.

A Critical Appraisal of the Social Norms Approach as an Interventional Strategy for Health-Related Behavior and Attitude Change

The Social Norms Approach is a widely used intervention strategy for promoting positive health-related behaviors. The Approach operates on the premise that individuals misperceive their peers' behaviors and attitudes, with evidence of under- and over-estimations of behaviors and peer approval for a range of positive and negative behaviors respectively. The greater these misperceptions, the more likely an individual is to engage in negative behaviors such as consuming heavier amounts of alcohol and other substances and reduce positive behaviors such as eating healthily and using sun protection. However, there are many complexities associated with the use of social norms feedback in interventions and empirical studies. Many social norms interventions do not attempt to change misperceptions of social norms or measure changes in normative perceptions pre- and post-intervention. This has led to a conflation of generic social norms interventions with those that are explicitly testing the Approach's assumptions that it is misperceptions of peer norms which drive behavior. The aim of the present review was to provide a critical appraisal of the use of the Social Norms Approach as an intervention strategy for health-related behaviors, identify the current issues with its evidence base, highlight key opportunities and challenges facing the approach, and make recommendations for good practice when using the approach. There are three core challenges and areas for improved practice when using the Social Norms Approach. Firstly, improvements in the methodological rigor and clarity of reporting of 'social norms' research, ensuring that studies are testing the approach's assumption of the role of misperceptions on behaviors are differentiated from studies investigating other forms of 'social norms.' Secondly, the need for a more explicit, unified and testable theoretical model outlining the development of normative misperceptions which can be translated into interventional studies. Finally, a need for a more robust evaluation of social norms interventions in addition to randomized controlled trials, such as the inclusion of process evaluations, qualitative studies of participant experiences of social norms feedback, and alternative study designs better suited for real-world public health settings. Such improvements are required to ensure that the Social Norms Approach is adequately tested and evaluated.

A quantification of the alcohol use-consequences association in college student and clinical populations: A large, multi-sample study

BACKGROUND

The present study sought to quantify the relationship between alcohol use and alcohol-related consequences in both college student and clinical samples.

METHODS

We gathered 33 college student datasets comprising of 15,618 participants and nine clinical sample datasets comprising of 4,527 participants to determine the effect size of the relationship between alcohol use and alcohol-related consequences. We used random-effects meta-analytic techniques, separately in college and clinical samples, to account for a distribution of true effects and to assess for heterogeneity in effect sizes.

RESULTS

Results demonstrated that the clear majority of the variability in alcohol-related consequences is not explained by alcohol use (ie, >77% in college samples; >86% in clinical samples), and that there was significant heterogeneity in all effect sizes.

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

Experiencing alcohol-related consequences results from factors that extend beyond frequency and quantity of alcohol consumed suggesting a need to examine other predictors of alcohol-related consequences beyond alcohol use. (Am J Addict 2018;27:116-123).

Adolescent drinking, social identity, and parenting for safety: Perspectives from Australian adolescents and parents

We explored young people and parents' views on adolescent drinking and safety in the locations where drinking may occur. Focus groups with adolescents and parents showed that many believed adolescent drinking and drunkenness is normative. Younger adolescents had more negative views of adolescent drinkers than their older peers. Adolescent drinking occurred in private settings and parents made decisions about allowing their adolescent children to attend social events based on the level of safety attributed to the location. If adolescent drinking was likely then home was the preferred location as it provided scope for risk minimisation. Positive portrayals of non-drinking adolescents and information to assist parents' decision-making are needed.
