Using a four-wave/seven-month longitudinal design with a sample of 1595 preadolescents (53% boys, 47% girls, Mage = 10.2 years) from 63 fourth-, fifth- and sixth- grade classrooms in nine mixed-sex schools in Bogota, Colombia, we examined whether growth trajectories of measures of overt and relational aggression varied as a function of classroom norms for aggression. Multilevel growth mixture modeling revealed (a) distinct trajectories of overt and relational aggression for boys and girls and (b) that norm salience (i.e., the process by which a group norm is made salient via the punishments or reinforcements to the behavior within the group) was a better predictor of associations with trajectories of overt and relational aggression than were perceived injunctive norms (i.e., the perceived standards of what is approved or disapproved in a social context). In classrooms where popular or accepted children were perceived by their peers as aggressive, more boys followed an increasing trajectory of overt and relational aggression than a low-stable trajectory, and more girls followed a high-stable trajectory of relational aggression than a low-stable trajectory. These findings are discussed in terms of the practical implications for the design of educational interventions aimed at preventing aggression in classroom settings.

Communication with family members about the COVID-19 vaccine may play an important role in vaccination decisions, especially among young people. This study examined the association between family communication about the COVID-19 vaccine and vaccination intention. Participants were Black/African Americans aged 18–30 years (N = 312) recruited through an online survey in June 2020. We assessed family communication, vaccine attitudes, perceived norms, outcome expectancies, and vaccination intention. More than half (62%) of the participants had talked to family members about the vaccine. Females were more likely than males to have engaged in family communication (63% vs. 59%) (p. > .05). Family communication, injunctive norms, and descriptive norms were significantly (p. < .01) associated with vaccination intention. Family communication was the strongest predictor of intention. Promoting discussions about vaccinations between young Black adults and their families may increase the likelihood of adopting positive vaccination beliefs and influencing vaccine decision-making.

Background: Cannabis use rates are rising among college students, creating a need for effective and accessible intervention options. One such intervention, the Marijuana eCHECKUP TO GO (eCTG) program, has relatively few studies investigating mechanisms of change and related outcomes. This intervention provides users with personalized normative feedback to adjust user's normative perceptions and use patterns. The current study tested moderated mediation of program effects between the eCTG intervention condition and a healthy stress management (HSM) control condition in a college student sample of near-daily cannabis users. Protective behavioral strategies (PBS) were measured among the eCTG conditionMethods: Data were analyzed from a sample of 227 students who were randomly assigned to the eCTG intervention condition or HSM control condition. Change in cannabis use frequency was measured by re-administering the baseline survey at a six-week follow-up. Multi-group moderated mediation path analysis tested the effects of the eCTG intervention on change in cannabis use frequency through PBS, descriptive norms, and injunctive norms, with multi-group categories defined by sex.Results: Direct effects indicated the intervention predicted reduced descriptive norm perceptions and cannabis use frequency. An indirect effect was found for the intervention condition on reducing cannabis use frequency through change in descriptive norms in males. Similarly, an indirect effect was seen for intervention condition on reducing cannabis use frequency through change in injunctive norms for females.Conclusions: Findings suggest changes in descriptive norms played a sex-specific mediating role in the mechanisms of change for the eCTG intervention on reductions in cannabis use frequency.

Social norms positively predict college students' alcohol use, but it is critical to explore heterogeneity in these patterns to identify which students are most susceptible to normative influences. The current study explored the nature of drinking norms within college student peer sport clubs. We examined the association between self-reported alcohol use (i.e., number of drinks in a typical week) and perceived descriptive/injunctive norms as an indicator of norm adherence and then tested moderating effects of social constructs related to the group: Social identification with one's team, along with social network-derived indices of indegree centrality and network density. We sampled members of 35 intact college club sport teams at 3 timepoints across the school year (N = 1,054; 61% female). Multilevel modeling was employed to estimate moderating effects at within-person, between-person, and between-groups levels. Initial analyses revealed that perceived group norms predicted self-reported alcohol use, and that teams approached consensus on the groups' drinking norms over time. Several significant time-varying moderation patterns were uncovered. At timepoints when students identified more strongly with their team (relative to person-mean levels), they more readily adhered to perceived descriptive and injunctive team drinking norms. Students also adhered more closely to these perceived team drinking norms at timepoints when students were nominated as having relatively lower indegree centrality. Cross-level interactions revealed that neither network density nor team sex moderated these associations. Taken together, the current findings advance our understanding of group processes that may produce more salient social influences on students' alcohol use behaviors within proximal peer groups.

Objectives This study addresses a need for quantitative research examining factors supporting the frequent use of homophobic language (e.g., fag) in male team sports which has a range of negative health impacts on gay and bisexual males. Intervention methods are needed to stop this behaviour, but little is known about why this language remains common. Design Cross-Sectional survey. Method Male Rugby Union (n = 97; ages 16 -18 years) and Ice Hockey players (n = 146; ages 16 - 31 years) self-reported their use of homophobic language and completed measures of homophobic attitudes and descriptive and injunctive norms related to language use on their team. Bivariate and multivariate analyses examined factors associated with this behaviour. Results Over half of participants (53.8%) self-reported using homophobic language at least once in the previous two weeks. No relationship was found between homophobic attitudes and language use. In contrast, norm measures had a strong, positive relationship with this behaviour. In multivariate analyses, norms uniquely accounted for almost one-half of the variance in language use. The addition of descriptive norms into the full model led to the largest increase in R2 of .340 (F(1,200) = 130.816, p Conclusions Homophobic language use was related to norms, rather than homophobic attitudes. Interventions targeting changes to these norms could be an effective method to change this behaviour. This finding contributes to a growing body of evidence that norms are associated with a range of negative behaviours by male athletes.

Objectives\ud \ud To examine associations between demographics, people’s beliefs, and compliance with behaviours recommended by the UK government to prevent the transmission of the SARS‐CoV‐2 virus that causes COVID‐19.\ud \ud \ud \ud Design\ud \ud A two‐wave online survey conducted one week apart during the national lockdown (April, 2020).\ud \ud \ud \ud Measures\ud \ud A sample of 477 UK residents completed baseline measures from the reasoned action approach (experiential attitudes, instrumental attitudes, injunctive norms, descriptive norms, capacity, autonomy, and intention) and perceived susceptibility for each of the following recommended behaviours: limiting leaving home, keeping at least 2 m away from other people when outside and when inside shops, not visiting or meeting friends or other family members, and washing hands when returning home. Self‐reported compliance with each of the recommended behaviours was assessed one week later.\ud \ud \ud \ud Results\ud \ud Rates of full compliance with the recommended behaviours ranged from 31% (keeping at least 2 m away from other people when inside shops) to 68% (not visiting or meeting friends or other family members). Capacity was a significant predictor of compliance with each of the five recommended behaviours. Increasing age and intentions were also predictive of compliance with three of the behaviours.\ud \ud \ud \ud Conclusions\ud \ud Interventions to increase compliance with the recommended behaviours to prevent the transmission of the SARS‐CoV‐2 virus, especially those relating to social distancing, need to bolster people’s intentions and perceptions of capacity. This may be achieved through media‐based information campaigns as well as environmental changes to make compliance with such measures easier. Such interventions should particularly target younger adults.

Background Sexual violence—any sexual act committed against a person without freely given consent—disproportionately affects women. Women’s first experiences of sexual violence often occur in adolescence. In Asia and the Pacific, 14% of sexually experienced adolescent girls report forced sexual debut. Early prevention with men that integrates a bystander framework is one way to address attitudes and behavior while reducing potential resistance to participation. Methods This paper describes a study protocol to adapt RealConsent for use in Vietnam and to test the impact of the adapted program—GlobalConsent—on cognitive/attitudinal/affective mediators, and in turn, on sexual violence perpetration and prosocial bystander behavior. RealConsent is a six-session, web-based educational entertainment program designed to prevent sexual violence perpetration and to enhance prosocial bystander behavior in young men. The program has reduced the incidence of sexual violence among men attending an urban, public university in the Southeastern United States. We used formative qualitative research and the Centers for Disease Control and Prevention’s Map of the Adaptation Process to adapt RealConsent. We conducted semi-structured interviews with college men (n = 12) and women (n = 9) to understand the social context of sexual violence. We conducted focus group discussions with university men and stakeholders (n = 14) to elicit feedback on the original program. From these data, we created scripts in storyboard format of the adapted program. We worked closely with a small group of university men to elicit feedback on the storyboards and to refine them for acceptability and production. We are testing the final program—GlobalConsent—in a randomized controlled trial in heterosexual or bisexual freshmen men 18–24 years attending two universities in Hanoi. We are testing the impact of GlobalConsent (n = 400 planned), relative to a health-education attention control condition we developed (n = 400 planned), on cognitive/attitudinal/affective mediators, prosocial bystander behavior, and sexual violence perpetration. Discussion This project is the first to test the impact of an adapted, theoretically grounded, web-based educational entertainment program to prevent sexual violence perpetration and to promote prosocial bystander behavior among young men in a middle-income country. If effective, GlobalConsent will have exceptional potential to prevent men’s sexual violence against women globally.

The theory of planned behavior (TPB) is used to document children’s health behaviors linked to their physical activity. The TPB model and its components have been applied to comprehend the adoption of physical activity along informational and motivational parameters. Thus, this exploratory study aims to assess the evolution of children’s physical activity levels (MVLPA) during the first weeks of their cancer, in addition to documenting the evolution of the TPB measures, self-reported fitness, and self-esteem in the physical domain to better understand children’s physical activity behavior. A total of 16 children (8 boys and 8 girls) with cancer answered psychosocial questionnaires at the diagnosis of cancer (time 1) and at 6 to 8 weeks (time 2) to assess the TPB measures, self-reported fitness, self-esteem in the physical domain, and their daily physical activities. A significant decrease of 41.2 min/days of daily MVLPA was observed between the time at cancer diagnosis (50.5 ± 32.8 min/days) and 6 to 8 weeks after the first interview (9.3 ± 9.1 min/days). We found that the time after the diagnosis of cancer negatively impacted children’s TPB measures (mean in attitude, injunctive norms, identity, facilitating factors, self-confidence, and intention) and MVLPA levels. The TPB model explains 40% of the variance in MVLPA by the injunctive norms during the first weeks following cancer diagnosis in children. The findings of this study highlight the negative impacts of cancer on children’s TPB measures, self-reported fitness, and self-esteem in the physical domain and self-reported MVLPA levels over 4 to 6 weeks following the diagnosis. These findings help to better understand the effect of cancer diagnosis on children’s physical activity behavior.

[Correction Notice: An Erratum for this article was reported in Vol 34(4) of Psychology of Addictive Behaviors (see record 2020-38542-001). In the article, the description of the prospective sample in the second sentence of the second paragraph and the second sentence of the third paragraph of the Participants section is incorrect. The description should appear, respectively, as follows: These were participants who were contacted if they reported at least one heavy drinking day (≥4 drinks for women and ≥5 drinks for men) in both a 30-day retrospective assessment and a 30-day daily diary reporting phase at Wave 1. . . . Of these, 1,141 were identified as moderate to heavy drinkers. Due to a coding error, 23 of these individuals did not meet these criteria but were contacted for Wave 2. However, all of these individuals reported drinking levels at Wave 1 (using a drinking composite comprised of standardized retrospective and daily diary drinking variables) within the range of values for the individuals who met the correct criteria. All were retained for analysis and 906 (79%) completed at least 15 days of recording in Wave 2.²] Despite the wealth of research on the effects of drinking norms on college students' alcohol consumption, researchers have not yet examined changes in drinking norms and their association with drinking level after students leave the college environment. The current study filled this gap by following students into postcollege life, measuring drinking norms and daily drinking behavior. College students (N = 1,848) were recruited to take part in a daily diary study measuring social and solitary alcohol consumption, and 1,142 moderate to heavy drinkers from the college cohort were invited to complete a second wave of daily diaries 5 years later, with 906 providing at least 15 days of diary data in each wave. Results of multilevel modeling analyses suggest that family injunctive drinking norms become more strongly related to alcohol consumption after individuals leave college. In contrast, institutional injunctive norms may have a greater limiting effect among college students (i.e., the association was greater among college students) and the relations between friend injunctive and descriptive norms to drinking behavior did not change between waves in the current study. This suggests that friend drinking continues to be related to own drinking behavior among adults after leaving the college environment, and highlights the changing importance of institutional norms and family approval. These results may have implications for intervening in young adults' heavy drinking. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Many efficacious interventions designed to reduce college student drinking aim to correct misperceptions of peers' drinking behavior. The present study tested the efficacy of a novel delivery strategy, namely text messages, for promoting promoderation descriptive and injunctive drinking norms. Participants included 121 college students who were randomly assigned to receive daily text messages containing accurate drinking norms (experimental group, n = 61) or historical facts (control group, n = 60) for 10 weeks following a baseline assessment. Participants completed 3-month postbaseline and 6-month postbaseline follow-up assessments. The 3-month assessment revealed that promoderation text messages were effective for reducing peak consumption and alcohol consequences. Changes in descriptive norms and injunctive norms aligned with these two behavioral outcomes. The intervention group reported perceiving others as drinking less on their heaviest drinking day and perceived others as being less approving of alcohol-related consequences than the control group. The intervention group also reported more peer approval of using protective behavioral strategies. Yet intervention effects were not maintained. None of the outcome measures differed by condition at the 6-month postbaseline assessment. Thus, the intervention had short-term effects on self-reported drinking behavior as well as on perceptions of drinking norms. However, the behavioral changes were not maintained when participants were assessed in the second semester after the daily text messages intervention had stopped.

BACKGROUND. Students’ alcohol use behaviors are shaped by the attitudes and behaviors of others, especially the peers within students’ proximal social groups. Explaining the association between perceived drinking norms and alcohol use, researchers propose contradicting pathways that focus on conformity (i.e., social norms predict alcohol use) and projection (i.e., alcohol use predicts perceived norms). The current study examined the extent to which conformity and projection processes were evident in the association between college student alcohol use and the perceived alcohol use norms for students’ club sport teams. METHOD. The sample comprised 1,054 college students (61% female) nested in 35 intact same-sex club sport teams. On three separate occasions during a single school year (three-month lag), participants reported drinking frequency and perceptions of descriptive and injunctive group drinking norms. We employed random intercepts cross-lagged panel modeling to estimate prospective within-person associations separately from stable trait-like between-person associations. RESULTS. Descriptive and injunctive group drinking norms were both positively related to students’ alcohol use frequency at the between-person level. Individuals nevertheless demonstrated variability at the within-person level. Results revealed a strong contemporaneous association between descriptive norms and alcohol use frequency within each time point, but no prospective associations. Models including perceptions of injunctive drinking norms demonstrated similar contemporaneous associations with alcohol use frequency, but also identified significant prospective associations signifying conformity. CONCLUSION. Findings align with previous research reporting a strong and positive association between student’s self-reported alcohol use and subjective peer alcohol use norms. After disentangling within- and between-person effects to probe for conformity and projection processes, the current findings are somewhat contrary to previous research that has reported reciprocal relationships between social norms and alcohol use behavior. Further investigation of the potential conformity and projection mechanisms of social norms is critical to advance norm-based strategies to reduce harm.

Anti-vaccine conspiracy beliefs among parents can reduce vaccination intentions. Parents’ beliefs in anti-vaccine conspiracy theories are also related to their perceptions of other parents’ conspiracy beliefs. Further, research has shown that parents hold misperceptions of anti-vaccine conspiracy belief norms: UK parents over-estimate the anti-vaccine conspiracy beliefs of other parents. The present study tested the effectiveness of a Social Norms Approach intervention, which corrects misperceptions using normative feedback, to reduce UK parents’ anti-vaccine conspiracy beliefs and increase vaccination intentions. At baseline, 202 UK parents of young children reported their personal belief in anti-vaccine conspiracy theories, future intentions to vaccinate, and their perceptions of other UK parents’ beliefs and intentions. Participants were then randomly assigned to a normative feedback condition (n = 89) or an assessment-only control condition (n = 113). The normative feedback compared participants’ personal anti-vaccine conspiracy beliefs and perceptions of other UK parents’ beliefs with actual normative belief levels. Parents receiving the normative feedback showed significantly reduced personal belief in anti-vaccine conspiracy beliefs at immediate post-test. As hypothesised, changes in normative perceptions of anti-vaccine conspiracy beliefs mediated the effect of the intervention. The intervention, did not directly increase vaccination intentions, however mediation analysis showed that the normative feedback increased perceptions of other parents’ vaccination intentions, which in turn increased personal vaccination intentions. No significant effects remained after a six-week follow-up. The current research demonstrates the potential utility of Social Norms Approach interventions for correcting misperceptions and reducing anti-vaccine conspiracy beliefs among UK parents. Further research could explore utilising a top-up intervention to maintain the efficacy.

Exposure to online drinking on social media is associated with real-life alcohol consumption. Building on the Theory of planned behavior, the current study substantially adds to this line of research by identifying the predictors of sharing drunk references on social media. Based on a cross-sectional survey among 1639 adolescents with a mean age of 15 (59% female), this study compares and discusses multiple regression tree algorithms predicting the sharing of drunk references. More specifically, this paper compares the accuracy of classification and regression tree, bagging, random forest and extreme gradient boosting algorithms. The analysis indicates that four concepts are central to predicting adolescents’ sharing of drunk references: (1) exposure to them on social media, (2) the perceived injunctive norms of the mother towards alcohol consumption, (3) the perceived descriptive norms of best friends towards alcohol consumption, and (4) willingness to drink alcohol. The most accurate results were obtained using extreme gradient boosting. This study provides theoretical, practical, and methodological conclusions. It shows that maternal norms toward alcohol consumption are a central predictor for sharing drunk references. Therefore, future media literacy interventions should take an ecological perspective. In addition, this analysis indicates that regression trees are an advantageous method in youth research, combining accurate predictions with straightforward interpretations.

Background Norm-correcting interventions are an effective alcohol harm-reduction approach, but innovation is needed to increase modest effect sizes. Recent social psychology research shows that individuals may be influenced by social norms that are increasing in prevalence. Contrary to static norms that reflect the current state of normative behavior, dynamic norms reflect behavioral norms that are shifting over time. This proof-of-concept study tested the utility of dynamic norms messages within norm-correcting interventions. Method Undergraduate student drinkers (N = 461; Mage = 19.97; 64.43% female) were randomly assigned to receive (a) dynamic norms messages highlighting a steady decrease over the past six years in heavy drinking among college students; (b) static norms messaging stating only the current norms; or (c) a control condition without normative information. Proximal outcomes assessed immediately following the experimental paradigm included intentions for total weekly drinks and heavy episodic drinking. Self-reported information on alcohol use behavior was collected at 1-month follow-up. Results Following the experimental paradigm, participants in the dynamic norms condition estimated that future drinking norms would decrease, while those in the static norms and control groups estimated that future drinking norms would increase. Participants in the dynamic norms condition reported lower intentions for weekly drinks and heavy episodic drinking than those in the static norms and control conditions. No significant differences between conditions were found on alcohol use indices reported at the 1-month follow-up. However, dynamic norms messaging had a favorable indirect effect on heavy episodic drinking intentions mediated through lower perceived future drinking norms. Conclusions These findings provide proof-of-concept that dynamic norms messaging may be a prudent strategy for reducing alcohol use intentions, which can be integrated into or used alongside existing norm-correcting strategies.

A detailed understanding of the factors associated with support among youth for reporting a knife or gun at school to an adult is essential to inform violence prevention initiatives. However, no studies have empirically assessed attitudes about support for reporting among secondary school students in Greater London nor perceived norms about such support among peers. Thus, this study explores whether students misperceive peer norms about support for telling adults about seeing weapons at school. Anonymous surveys were completed by 7,401 youth (52% female; 43% White; mean age 11.8 years) in school years 4 to 11 in 45 school cohorts in a greater London borough between 2007 and 2012. Students reported both personal support about reporting weapons to several categories of adults and whether they perceived most other students at their school to support reporting weapons to adults in each category. Most students (64% to 78% on average) in most cohorts personally thought that students should report seeing a weapon at school to a head teacher, police officer, teacher or counsellor, and parent or another adult relative. However, 34% to 44% of students erroneously thought that the majority of their peers did not support reporting to these adults. Perceived norms predicted personal support for reporting, adjusting for the prevalence of actual support at one’s school and other factors. Pervasive norm misperceptions about reporting may contribute to a less safe environment.

The sexual exploitation of children and adolescents is a frequently underestimated health problem which includes transactional sex (TS), or the practice of sexual activity based on an expected return of benefits, favours and/or support in some form. This qualitative study focuses on age-disparate transactional sex (ATS) in urban favela communities of Rio de Janeiro between adult men (over 18) and girls and adolescents (G/A) (under 18), involving a minimum 5-year age disparity. We have employed social norms theory as a framework to identify the prevailing social norms contributing to or protecting children and adolescents from these relationships. Data collection utilised semi-structured interviews (n = 30) and ten focus groups with a total of 130 men/boys and women/girls selected through purposive sampling and varying in age from 15 to 65. Overall the findings identify factors, especially the essentialisation of gender, which promote the acceptability of ATS. When ATS surpassed the acceptability threshold, social norms discouraged direct interference. Concluding remarks point to possible strategies for reducing the occurrence of ATS. These must include girls, boys, women and men with community involvement in the deconstruction of social norms involving gender, age and economic consumption.

Background Interaction within mothers’ social networks can theoretically diffuse messages from interventions and campaigns into norms and practices for infant and young child feeding (IYCF). Objectives We hypothesized that mothers’ social networks, diffusion of information, and social norms differed in intensive [intensive interpersonal counseling (IPC), community mobilization (CM), and mass media (MM)] compared with nonintensive (standard IPC and less-intensive CM and MM) intervention areas, were associated with IYCF practices, and partly explained practice improvement. Methods We conducted household surveys at endline in 2014 and follow-up in 2016 (n = ∼2000 each round). We used multiple regression to test differences and changes in networks, diffusion, and norms within intervention areas. We analyzed paths from intervention exposure to IYCF practices through networks, diffusion, and norms. Results Mothers’ networks were larger in intensive than in nonintensive areas in 2014 and increased in both areas over time [25–38 percentage points (pp)]. The prevalence of receipt of IYCF information was high, with no changes over time in intensive areas but an increase in nonintensive areas (8–16 pp). In both areas, more family members and health workers provided IYCF information over time. Sharing of information increased 17–23 pp in intensive and 11–41 pp in nonintensive areas over time. Perceived descriptive norms improved 8–16 pp in intensive and 17–28 pp in nonintensive areas. Perceived injunctive norms were high in both areas. Breastfeeding practices were associated with networks, diffusion, and norms (OR: 1.6–4.4 times larger comparing highest with lowest quartile). Minimum dietary diversity was associated with larger networks and diffusion (OR: 1.5–2.2) but not with social norms. Indirect paths from intervention exposure to practices explained 34–78% of total effects. Conclusions Diffusion of IYCF information through social networks, reinforced by positive social norms for messages promoted over time, will contribute to positive changes in IYCF practices that may be achieved and sustained through large-scale social and behavior change interventions. This trial was registered at clinicaltrials.gov as NCT0274084.

There is growing attention to how social processes in communities may contribute to domestic and sexual violence (DSV) and be a target for prevention efforts. Three main variables are collective efficacy and descriptive and injunctive norms. To date, few measures exist that assess these variables in the specific context of violence prevention. The current study sampled 3,866 adults and high-school youth in four communities in northern New England. Exploratory and confirmatory factor analyses examined the psychometrics of the scales. Scales reflecting collective efficacy, indirect public, and direct individualized descriptive norms, public and personal injunctive norms, and youth perceptions of adults' prevention actions demonstrated robust factor structures and adequate reliability and validity. These measures may prove useful for a diverse audience (e.g., practitioner, researchers) for assessing the effectiveness of community-level DSV prevention strategies.

Background: Nonmedical prescription stimulant (NPS) use for academic reasons (e.g., to improve concentration) is a growing problem among college students. However, there is limited theory-driven research that attempts to identify risk cognitions underpinning decisions to use and NPS use for academic purposes. Furthermore, it is unclear if academic NPS use is characterized by deliberative and/or socially reactive processing and what health decision-making model or combination of models best predicts NPS use decisions and use. Identifying cognitions associated with NPS use decisions is essential to develop interventions aimed at preventing and reducing NPS use. Objective: The present study tested the Theory of Reasoned Action (TRA), Prototype/Willingness Model (PWM), and a combined TRA/PWM model to identify which model best predicts academic NPS use decisions (willingness and intentions) and past 2-month use among college students. Method: Undergraduates (N = 344) participated in a two-wave study assessing T1 constructs from the TRA and PWM as predictors of T2 (2 months later) academic NPS use decisions and use. Results: In the combined TRA/PWM, all T1 constructs were associated with T2 NPS willingness, intentions, and use except for injunctive norms. The integrated model also explained greater variance in T2 use, willingness, and intentions than each model alone. Conclusions/Importance: The combination of cognitions from the TRA/PWM was superior to each individual model and improved the prediction of future NPS use willingness, intentions, and use. The overall results derived from all three models suggest that both deliberative and socially reactive processing influence and characterize academic NPS use decisions and use.

Alcohol-related blackouts are a common, yet serious consequence that can result from heavy alcohol intake. This study tested a model examining whether factors identified in related samples (i.e., adolescents residing in the U.K. and U.S. college students) predicted blackouts in community-dwelling U.S. high school youth. Participants from a Northeastern U.S. high school with prior alcohol use (Mage = 16.0 years; 48.2% male, 78.0% White) completed a paper-and-pencil assessment including measures of demographics, alcohol and other substance use, externalizing behaviors, and injunctive norms about risky drinking behaviors. Hierarchical logistic regression examined which factors identified for U.K. residing adolescents (Block 1) replicated in the U.S. sample, and whether factors identified in samples of U.S. college students added additional explained variance (Block 2). Blackouts were reported by 35.6% of students. Regression results indicated that two variables previously identified in adolescents, female gender (OR = 3.26) and increased alcohol use (OR = 1.27) were associated with blackouts. College student risk factors of drinking game (DG) participation and, to a lesser degree injunctive norms for passing out, emerged as additional risk factors (ORs = 2.85 and 1.32, respectively), with the final model explaining 39% of the variance in blackouts. This study advances our understanding of blackouts in younger drinkers and identifies the importance of addressing blackouts within the context of intervention programming that addresses cognitions and high risk drinking practices like DGs.

Introduction Alcohol is the most commonly used substance by South African adolescents. Social norms play a key role in alcohol use, although distinctions are not always made between descriptive and injunctive norms and peer proximity. Additionally, little research identifies factors attenuating social norms, peer proximity, and alcohol use, such as one's ability to resist peer influence. Methods The current study investigates the relationship between adolescent alcohol use in 9th Grade and descriptive peer and injunctive friend norms in 8th grade, the moderating role of resistance to peer influence, and sex differences. Data were from South African students (N = 3592; Mage = 14) participating in the HealthWise South Africa implementation quality trial. Results Path model results indicated injunctive friend norms, but not peer norms, influenced alcohol use. Resistance to peer influence did not moderate relationships and group comparisons found no sex differences. Conclusion Findings suggest social proximity shapes influences of alcohol use. Despite a differing cultural context, findings were consistent with those from the United States, indicating social proximity is relevant cross-culturally.

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, the current 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.

Universal school-based substance use prevention programs are widely disseminated and often include a focus on peer relationships. Network theory and social network analysis (SNA) have emerged as useful theoretical and methodological frameworks for examining the role of peer relationships in prevention and intervention research. We used content analysis to systematically code the peer processes targeted by three universal school based prevention programs. We found that programs focused on peer socialization more than peer selection, and programs focused about evenly on descriptive and injunctive norms. Programs varied in their focus on positive and negative peer processes and behaviors, but most references to peer processes focused on positive processes and negative behaviors. The focus on peer processes at the dyadic, subgroup, and network levels varied across the three programs, with the heaviest focus on network level processes. When peer processes were targeted, it was rare that lessons focused on peer processes for an extended (> 50%) amount of the lesson content. However, when peer processes were a focus, discussion and reflection were commonly encouraged. These patterns are considered in the context of non-intervention research on adolescent peer relations, which highlights the importance of peer selection and dyad-level processes, and the existence of positive peer processes that promote adolescent development. In doing so, we provide a framework that can be used to (1) examine the extent to which a particular program focuses on the different peer processes, and (2) inform systematic experimental studies of the extent to which particular peer processes are malleable in response to intervention efforts.

Objective Prior research has documented the influence of social norms on health-related behaviors, though social norms may affect behaviors in more complex ways than have conventionally been modeled. The present research evaluates parent norms and teens' own attitudes as moderators of associations between perceived peer norms and diet and physical activity behaviors (both health-promoting and health-impairing) in a national sample of U.S. adolescents. Methods Adolescent participants (N = 1,859; ages 12-17) from the 2014 Family Life, Activity, Sun, Health, and Eating study reported on the extent to which their friends eat fruits and vegetables; eat junk food or drink sugary drinks; exercise; and watch TV, play on the computer, or play electronic games most days of the week. They also reported on their own attitudes and behaviors as well as their parents' corresponding behaviors and rules. Results Perceived peer norms were associated with teens' own health-promoting behaviors such as fruit and vegetable consumption and physical activity as well as health-impairing behaviors such as junk food consumption and sedentary habits. Teens who reported liking fruits and vegetables or physical activity or perceiving congruent descriptive parental norms demonstrated the strongest positive associations between peer norms and their own behavior. Conclusions Perceived social norms may play a significant role in both health-impairing and health-promoting behaviors, particularly when congruent with attitudes or descriptive parental norms about those behaviors. The findings may inform interventions such as social norms marketing campaigns that aim to change perceptions of peer norms for health-promoting behavior.

The use of corporal punishment (CP) is a strong risk factor for many poor outcomes for children including child maltreatment. The use of CP occurs within social contexts which are important to understand. Although it is known that perceived social norms regarding CP are related to its use, the specific role that a mother’s primary support person plays in influencing attitudes toward and use of CP remains unknown. The current study assessed linkages between maternal perceived social support in parenting and perceived injunctive norms of CP from her primary source of support, with maternal attitudes toward and use of CP. Survey data were collected from female primary caregivers (N = 436) of children age 2 to 7 years (mean age = 3.7) enrolled in Special Supplemental Nutrition Program for Women, Infants and Children (WIC) clinics in Southeastern Louisiana. Most frequently, the biological father of the child (37.9%) and the maternal grandmother of the child (24.2%) were identified as the participant’s primary source of social support in parenting. Perceived injunctive norms of this support person toward CP use were significantly and positively associated with attitudes toward, AOR = 5.97, 95% CI = [4.04, 8.82], and use of CP, AOR = 3.77, 95% CI = [2.55, 5.59]. However, perceived social support was not associated with these outcomes and also did not moderate these associations. Findings suggest that efforts to reduce maternal risk for child physical abuse and use of CP must include the mother’s primary source of social support if they are to be successful.

Objectives To examine whether self-reported exposure to Testing Makes Us Stronger™ (TMUS), an HIV testing health communication campaign for black gay, bisexual, and other men who have sex with men (BMSM), was associated with key intermediate outcomes targeted by the campaign’s messages. Methods Data from sexually active, HIV-negative or unknown status BMSM aged 18–44 (N = 590) were collected through an anonymous Web-based survey that measured sociodemographics, campaign exposure, attitudinal beliefs, normative beliefs, self-efficacy, and HIV testing intentions, among other variables. The association between exposure to TMUS and intermediate outcomes was evaluated using propensity-score weight adjusted correlations. Results Exposure to TMUS was high (43%) among the priority audience. Exposure to the campaign was correlated with 8 of 11 intermediate outcomes measured, including key attitudinal beliefs about the accessibility of the test and benefits to the individual, injunctive norms, self-efficacy, and HIV testing intention. Conclusion Adhering to principles of effective campaign design, such as using theory as a conceptual foundation for message design, can increase a campaign’s chances for successfully meeting its goals and objectives. Practice Implications Findings from this study can be used to inform message design for other communication efforts to promote HIV testing among BMSM.

We propose and test several hypotheses derived from the expanded theory of normative social behavior (TNSB) that also includes collective norms (with descriptive and injunctive norms). Data come from a quasi-experiment intervention to promote safer driving among adolescents in Serbia. The intervention was administered among high school students, most of whom were on the verge of receiving their driver's licenses. Longitudinal data were collected from treatment and control schools at baseline (

From Catholics performing the sign of the cross since the 4th century to Americans reciting the Pledge of Allegiance since the 1890s, group rituals (i.e., predefined sequences of symbolic actions) have strikingly consistent features over time. Seven studies (N = 4,213) document the sacrosanct nature of rituals: Because group rituals symbolize sacred group values, even minor alterations to them provoke moral outrage and punishment. In Pilot Studies A and B, fraternity members who failed to complete initiation activities that were more ritualistic elicited relatively greater moral outrage and hazing from their fraternity brothers. Study 1 uses secular holiday rituals to explore the dimensions of ritual alteration-both physical and psychological-that elicit moral outrage. Study 2 suggests that altering a ritual elicits outrage even beyond the extent to which the ritual alteration is seen as violating descriptive and injunctive norms. In Study 3, group members who viewed male circumcision as more ritualistic (i.e., Jewish vs. Muslim participants) expressed greater moral outrage in response to a proposal to alter circumcision to make it safer. Study 4 uses the Pledge of Allegiance ritual to explore how the intentions of the person altering the ritual influence observers' moral outrage and punishment. Finally, in Study 5, even minor alterations elicited comparable levels of moral outrage to major alterations of the Jewish Passover ritual. Across both religious and secular rituals, the more ingroup members believed that rituals symbolize sacred group values, the more they protected their rituals-by punishing those who violated them.

Objective:To test the effectiveness of a social network intervention (SNI) to improve children’s healthy drinking behaviours.Design:A three-arm cluster randomised control trial design was used. In the SNI, a subset of children were selected and trained as ‘influence agents’ to promote water consumption–as an alternative to sugar-sweetened beverages (SSB)–among their peers. In the active control condition, all children were simultaneously exposed to the benefits of water consumption. The control condition received no intervention.Setting:Eleven schools in the Netherlands.Participants:Four hundred and fifty-one children (Mage= 10·74, SDage= 0·97; 50·8 % girls).Results:Structural path models showed that children exposed to the SNI consumed 0·20 less SSB per day compared to those in the control condition (β =0·25,P= 0·035). There was a trend showing that children exposed to the SNI consumed 0·17 less SSB per day than those in the active control condition (β =0·20,P= 0·061). No differences were found between conditions for water consumption. However, the moderation effects of descriptive norms (β= –0·12,P= 0·028) and injunctive norms (β= 0·11–0·14, bothP= 0·050) indicated that norms are more strongly linked to water consumption in the SNI condition compared to the active control and control conditions.Conclusions:These findings suggest that a SNI promoting healthy drinking behaviours may prevent children from consuming more SSB. Moreover, for water consumption, the prevailing social norms in the context play an important role in mitigating the effectiveness of the SNI.

Unintended pregnancy is an important global health problem and frequently occurs during the immediate postpartum period. However, few studies have examined postpartum family planning (PPFP) intentions among adolescent girls and young women. This study assessed whether perceived norms and personal agency predicted PPFP intentions among first-time mothers age 15–24 in Kinshasa, the Democratic Republic of Congo. Data were derived from the 2018 Momentum Project baseline survey. Analysis was based on 2,418 nulliparous pregnant women age 15–24 who were approximately six months pregnant with their first child in six health zones of Kinshasa. Overall PPFP intentions were low and ten to thirteen percent of women stated they were very likely to discuss PPFP next month with (a) their husband/male partner and (b) a health worker, and to (c) obtain and (d) use a contraceptive method during the first six weeks following childbirth. The results of multivariable linear regression models indicated that the PPFP intention index was predicted by description norms, perceptions of the larger community’s approval of PPFP, normative expectations, perceived behavioral control, self-efficacy, and autonomy. Rejection of family planning myths and misconceptions was also a significant predictor. Interaction terms suggested that the association of normative expectations with PPFP intentions varied across ethnic groups and that the positive association of injunctive norms with PPFP intentions was significantly increased when the larger community was perceived to disapprove of PPFP use. Normative expectations and PPFP-related self-efficacy accounted for two-thirds of the variance in PPFP intentions. The results suggested that understanding different normative influences may be important to motivate women to use contraception in the immediate postpartum period. In addition to addressing institutional, individual, and social determinants of PPFP, programs should consider integrating norm-based and empowerment strategies.

This chapter reviews research on the group identity explanation of social influence, grounded in self-categorization theory, and contrasts it with other group-based explanations, including normative influence, interdependence, and social network approaches, as well as approaches to persuasion and influence that background group (identity) processes. Although the review primarily discusses recent research, its focus also invites reappraisal of some classic research in order to address basic questions about the scope and power of the group identity explanation. The self-categorization explanation of influence grounded in group norms, moderated by group identification, is compared and contrasted to other normative explanations of influence, notably the concept of injunctive norms and the relation to moral conviction. A range of moderating factors relating to individual variation, features of the intragroup and intergroup context, and important contextual variables (i.e., anonymity versus visibility, isolation versus copresence) that are particularly relevant to online influence in the new media are also reviewed.

Background The rising childhood obesity rate is a major public health challenge. The objective of this study is to examine key underlying mechanisms for peer-related social influence on preadolescents’ healthy eating behavior by including factors closely linked with the quality of preadolescents’ relationship with peers. Methods A cross-sectional study was conducted in a convenience sample of 278 Lithuanian preadolescents, recruited from a public school. A questionnaire containing sociodemographic questions, questions about food intake, peer-related social norms of healthy eating, social self-efficacy, vegetable preference, need for peer approval and feeling of belonging were applied. Data was analyzed using structural equation modeling. Results The results of the SEM showed that social self-efficacy predicts feeling of belonging to the peer group and need for peer approval. Feeling of belonging and need for peer approval predict actual intake of vegetables via injunctive norms of healthy eating. However, neither feeling of belonging nor need for peer approval predicted descriptive norms of healthy eating. Contrary to our expectations, descriptive norms were found to be unrelated with actual intake of vegetables, though vegetable preference predicted actual intake of vegetables. Vegetable preference was not predicted by injunctive or descriptive peers’ social norms of healthy eating. Conclusions The findings of this study offer insight for informing parents, teachers and for social norms marketing interventions by stressing the importance of social relations when the aim is to encourage healthy eating among preadolescents.

Background People’s eating behavior is assumed to be influenced by what other people do (perceived descriptive norms) and what others approve of (perceived injunctive norms). It has been suggested that adolescents are more susceptible to peer norms than parental norms, because they experience a strong need for group acceptance that leads to conforming to peer group norms. The current study examined changes in snacking behavior and four types of social norms (i.e., parental and peer descriptive and injunctive norms) that promoted fruit and vegetable intake among adolescents. This study was the first to examine whether snacking behavior also influenced norm perceptions by testing the directionality of these associations. Methods The study consisted of 819 participants (M [SD] age = 11.19 [1.36]; 46.1% boys), collected at three time points (T1 = 2016, T2 = 2017 and T3 = 2018) during the MyMovez project. Self-reported frequency of snack consumption, perceived parental and peer descriptive and injunctive norms were assessed. The primary analysis consisted of a series of cross-lagged autoregressive models specified in a structural equation modeling framework. Results Model comparisons testing the descriptive and injunctive norms in separate models and in an additional combined model revealed evidence for bi-directional associations between norms and snacking behavior. Descriptive peer and parent norms were not found to have an effect on subsequent snacking behaviors. Perceived injunctive parental norms were positively associated with healthy snack food intake and negatively associated with unhealthy snack intake (forward direction). Injunctive peer norms were negatively associated with healthy snack food intake. In addition, higher unhealthy snack food intake was negatively associated with the perception of descriptive and injunctive parental norms 1 year later (reversed direction). We did not find peer norms to be more closely associated with changes in snacking behaviors compared to parental norms. Conclusions Parents expecting their children to snack healthy had a positive influence on healthy snacking behavior whereas only acting as a healthy role model did not. Future research should address the possible interaction between descriptive and injunctive norms. Research should also take into account the bi-directional relations between eating behaviors and normative perceptions.

The current study examined the extent to which evaluative attitudes toward sexual aggression (i.e., positive or negative evaluative judgments about sexually aggressive behavior) mediate the association between injunctive norms (i.e., extent to which peers approve or disapprove of sexually aggressive behavior) and self-reported sexual aggression against women. Participants were 200 male undergraduate students. Approximately one in four males reported engaging in at least one sexually aggressive act since the age of 16. Participants with a history of sexual aggression also reported the highest likelihood of engaging in sexually aggressive behavior in the future. We tested two separate mediation models to examine the extent to which evaluative attitudes account for the link between injunctive norms and sexual aggression: one model with self-reported history of sexual aggression as the outcome and the other with likelihood of engaging in sexually aggressive behavior as the outcome. Results showed that more positive evaluative attitudes toward sexual aggression accounted for the association between injunctive norms and self-reported history of sexual aggression. Similarly, evaluative attitudes accounted for the link between injunctive norms and self-reported likelihood of engaging in sexually aggressive behavior in the future. Overall, these findings are consistent with theoretical and empirical explanations of sexual offending and general criminal behavior; however, this is the first study to explore the relationship between injunctive norms and evaluative attitudes in the context of explaining sexually aggressive behavior. If more rigorous research establishes a causal relationship between injunctive norms, evaluative attitudes, and sexually aggressive behavior, this would suggest that targeting these factors in prevention programs may reduce sexual aggression by male undergraduate students.

Purpose: To understand factors affecting adherence to GFD by celiac and non-celiac people through the application of behavioural theories, Integrative Model (IM) and Multi Theory Model (MTM). Methods: Analyses were conducted for a sample of 308 subjects, majority females, celiac and non-celiac. Adherence to GFD was measured considering two scales, self-declared adherence and scored adherence, in order to discern possible inconsistencies between what subjects believe and what they really do. Subsequently, adherence to GFD was modelled by considering constructs of MTM and IM. Moreover, the constructs were designed based on literature review. Ordered logit (OL) model was used to test the IM and MTM theoretical models. Results: The findings show that adherence to GFD is affected mainly by attitudes towards GFD, self-efficacy, injunctive norms, knowledge about GFD and perceptions that GF products are expensive. Between the two models, IM and MTM, results show that all constructs of IM explain the behavior. Contrary, for MTM, results indicate only some constructs of the MTM explain adherence to GFD. Conclusions: Results of this study should be considered for improving the adherence to GFD for celiac people. Furthermore, it is important to consider the non-celiac people’s perceptions for GFD and GF products. In other words an accurate information about the diet and products it is relevant for supporting people to make healthier food choices. Finally, as the results show, IM explain adherence to GFD better than MTM.

Background To reduce diet-related chronic disease, policymakers have proposed requiring health warnings on sugar-sweetened beverages (SSBs). Health warnings reduced purchases of these products by 22% in our recent randomized controlled trial, but the mechanisms remain unclear. Purpose We sought to identify the psychological mechanisms that explain why SSB health warnings affect purchase behavior. Methods In 2018, we recruited 400 adult SSB consumers to complete a shopping task in a naturalistic convenience store laboratory in North Carolina, USA. We randomly assigned participants to either a health warning arm (all SSBs in the store displayed a text health warning) or to a control arm (SSBs displayed a control label). Participants selected items to purchase with cash. Results Compared to control labels, health warnings elicited more attention, negative affect, anticipated social interactions, and thinking about harms (range of ds = 0.63–1.34; all p < .001). Health warnings also led to higher injunctive norms about limiting SSB consumption (d = 0.27, p = .008). Except for attention, all of these constructs mediated the effect of health warnings on SSB purchases (all p < .05). In contrast, health warnings did not influence other attitudes or beliefs about SSBs or SSB consumption (e.g., healthfulness, outcome expectations, and response efficacy). Conclusions Health warnings on sugar-sweetened beverages affected purchase behavior by eliciting negative emotions, increasing anticipated social interactions, keeping SSBs’ harms at top of mind, and shifting norms about beverage consumption. Results are consistent with recent studies of why tobacco warnings influence quitting behavior, pointing toward a general framework for understanding how health warnings affect behavior.

OBJECTIVE We conducted meta-analyses and meta-analytic structural equation modeling of longitudinal studies among cancer survivors to (a) quantify associations between psychosocial predictors and physical activity, (b) test how psychosocial predictors combine to influence physical activity, and (c) identify study, demographic, and clinical characteristics that moderate associations. METHOD Eligible studies used a longitudinal, observational design, included a sample of cancer survivors, and measured both a psychosocial predictor at baseline and physical activity at a later time-point. Of 2,431 records located through computerized searches, 25 independent tests (N = 5,897) met the inclusion criteria for the review. Random effects meta-analyses and meta-analytic structural equation modeling were conducted. RESULTS Eight psychosocial predictors of physical activity were identified. Self-efficacy (r+ = 0.26) and intentions (r+ = 0.33) were the strongest predictors in bivariate analyses. The structural equation models included attitudes, injunctive norms, self-efficacy, intentions, and physical activity (k = 22, N = 4,385). The model with the best fit, χ2(2) = 0.11, p = .95, root mean square error of approximation = .00, comparative fit index = 1.00, Tucker-Lewis index = 1.00, indicated that all specified paths were significant. Intentions were the strongest predictor of physical activity (β = 0.27, p < .001), and attitudes and self-efficacy were strong predictors of intentions (both βs = 0.29, ps < .001). Few significant moderators were observed. CONCLUSION This review indicates that self-efficacy and intentions are direct predictors of physical activity in cancer survivors. Further, attitudes and norms predict physical activity through intentions. Findings inform intervention development to increase physical activity engagement among cancer survivors.

Background The association between the residential fast food environment and diet has gained growing attention. However, why the food environment affects food consumption is under-examined. This study aimed to investigate neighbourhood social norms with respect to fast food consumption as a potential mediating pathway between residential fast food outlet exposure and residents’ fast food consumption. Methods A correlational study was conducted in which a nationwide sample of 1038 respondents living across The Netherlands completed a survey. Respondents reported their fast food consumption (amount/week) as well as perceived descriptive and injunctive norms regarding fast food consumption in their neighbourhood. Fast food outlet exposure was measured by the average count of fast food outlets within a 400 m walking distance buffer around the zip-codes of the respondents, using a retail outlet database. Regression models were used to assess associations between residential fast food outlet exposure, fast food consumption, and social norm perceptions, and a bootstrapping procedure was used to test the indirect -mediation- effect. Separate analyses were performed for descriptive norms and injunctive norms. Results There was no overall or direct association between residential fast food outlet exposure and residents’ fast food consumption. However, fast food outlet exposure was positively associated with neighbourhood social norms (descriptive and injunctive) regarding fast food consumption, which in turn were positively associated with the odds of consuming fast food. Moreover, results of the bootstrapped analysis provided evidence of indirect effects of fast food outlet exposure on fast food consumption, via descriptive norms and injunctive norms. Conclusions In neighbourhoods with more fast food outlets, residents were more likely to perceive fast food consumption in the neighbourhood as more common and appropriate. In turn, stronger neighbourhood social norms were associated with higher fast food consumption. Acknowledging the correlational design, this study is the first that implies that neighbourhood social norms may be a mediating pathway in the relation between the residential fast food environment and fast food consumption. Future research may examine the role of neighbourhood social norms in other contexts and explore how the changing food environment may shift our consumption norms.

RationalePrevious studies suggest injunctive norms (prompts of what people ought to do) are stronger predictors of healthy eating intentions, whereas descriptive norms (prompts of what people are doing) are stronger predictors of healthy eating behaviors. However, previous research provides little insight into why different norms influence children's health intentions and behaviors differently. In addition, no research has explored developmental differences in children's conformity to, or rejection of, different types of social normative influence. Thus, this paper adopts a developmental perspective to understand why children conform differently to descriptive and injunctive norm messaging on healthy eating.MethodAn experiment was done with 405 children in Germany aged 7 to 16. The research design was a 4 (social norms: descriptive vs. injunctive peer vs. injunctive authority vs. control) × 2 (developmental stage: middle childhood vs. adolescence) between-subject design. Children's healthy eating intentions and behaviors were collected as key dependent variables.Resultsand conclusions: The experimental results suggest that children mainly use a descriptive norm as an information shortcut to behaving “appropriately”. This should have a stronger impact on younger children than older ones, although both young and old children consider it easier to understand than an injunctive norm. The experimental results further suggest that an injunctive norm mainly influences children via activation of a motive for maintaining a positive self-image in public, rather than one of affiliation. These results are very important for social research on health, because they can explain why different social norms influence health intentions and behaviors differently. In addition, our finding that injunctive norm conformity is mainly used for impression management purposes can reconcile existing contradictory results on the impact of social norms on children.

Objective: While cigarette smoking in the United States has declined, the age range of smoking initiation has risen to include young adults. This study investigated the relationship of Theory of Planned Behavior constructs (TPB; attitudes, subjective norms, and perceived behavioral control [PBC]) to nonsmoking intention among college students. Participants: Participants were 619 students at a Southeastern US university (69.8% female, 70.8% ≤ age 21, and 73.5% white). Methods: Students were recruited by email in March 2013 to participate in an online TPB-based questionnaire. Results: Future-oriented attitudes and PBC predicted higher nonsmoking intention; subjective norms did not. Moderator analyses indicated injunctive norms were more influential for occasional smokers and PBC was less influential. Conclusions: Findings suggest TPB is useful in predicting nonsmoking intention, but differentially for nonsmokers and occasional smokers. Future work should consider the health-related utility of future-oriented attitudes toward nonhealth domains and the differing beliefs of occasional smokers.

Background Condoms are an important prevention method in the transmission of HIV and sexually transmitted infections as well as unintended pregnancy. Individual-level factors associated with condom use include family support and connection, strong relationships with teachers and other students, discussions about sexuality with friends and peers, higher perceived economic status, and higher levels of education. Little, however, is known about the influence of social norms on condom use among young men in Ethiopia. This study examines the effect of descriptive and injunctive norms on condoms use at last sex using the theory of normative social behavior. Methods A cross-sectional survey was implemented with 15-24 year old male youth in five Ethiopian regions in 2016. The analytic sample was limited to sexually active single young men (n = 260). Descriptive statistics, bivariate and multivariate logistic regressions were conducted. An interaction term was included in the multivariate model to assess whether injunctive norms moderate the relationship between descriptive norms and condom use. Results The descriptive norm of knowing a friend who had ever used condoms significantly increased respondents’ likelihood of using condoms at last sex. The injunctive norm of being worried about what people would think if they learned that the respondent needed condoms significantly decreased their likelihood to use condoms. The injunctive norm did not moderate the relationship between descriptive norms and condom use. Young men who lived closer to a youth friendly service (YFS) site were significantly more likely to have used condoms at last sex compared to those who lived further away from a YFS site. Conclusions Social norms play an important role in decision-making to use condoms among single young men in Ethiopia. The interplay between injunctive and descriptive norms is less straightforward and likely varies by individual. Interventions need to focus on shifting community-level norms to be more accepting of sexually active, single young men’s use of condoms and need to be a part of a larger effort to delay sexual debut, decrease sexual violence, and increase gender equity in relationships.

Norms have been suggested as important characteristics of the social-ecological context for defending victimized peers, but little is known about the contribution of student perceived injunctive norms (regarding the appropriateness of defending) imposed by peers and teachers. To investigate the role of these norms in defending, a sample of 751 early adolescents (51% female; Mage at Time 1:13 years) was assessed at two time points. Defending, as measured by peer- and self-ratings, decreased slightly over a six-month timespan. Three-level models (with time, students, and classrooms as the levels) indicated that both individual- and classroom-level perceived peer injunctive norms (but not teacher injunctive norms) had positive effects on defending over time regardless of the source of the information on defending (peers or self). These findings support programs that encourage defending through peer norms.

This study examined the moderating role of classroom injunctive norms salience regarding social withdrawal and regarding aggression in the longitudinal association between these behaviors and peer victimization. A total of 1,769 fourth through sixth graders (895 girls, M = 10.25 years, SD = 1.03) from 23 schools (67 classrooms) completed a peer nomination inventory in the fall (T1) and spring (T2) of the same academic year. Participants circled the name of each student who fit the description provided for social withdrawal, aggression, and peer victimization at T1 and T2. The salience of injunctive norms was sex-specific and operationalized by the extent to which children displaying the behavior were socially rewarded or sanctioned by their classmates. Generalized estimation equations (GEE) showed that the association between social withdrawal at T1 and peer victimization at T2 was moderated by injunctive norms. Social withdrawal at T1 was positively associated with peer victimization at T2 in classrooms where injunctive norms for this behavior were salient and unfavorable, as well as in classrooms where injunctive norms for aggression were salient and favorable, albeit for girls only. The association between aggression at T1 and peer victimization at T2 was also moderated by the injunctive norms regarding this behavior. Aggressive children were less likely to be victimized in classrooms where this behavior was rewarded. These results support bullying interventions that target factors related to the larger peer context, including social norms. (PsycINFO Database Record

Introduction Given the range of emergencies that beset postsecondary institutions, university administrators must take a multimodal approach to prepare campus stakeholders for safety threats. One such strategy is emergency preparedness communication. Methods In the present investigation, we tested the efficacy of a professionally produced video that uses the federally endorsed slogan, Run-Hide-Fight(r). Undergraduate students participated in a quasi-experiment with a pretest-posttest-delayed posttest control group design. Results Using the theory of planned behavior as our guiding framework, we found that video exposure increased attitudes, perceived norms, perceived behavioral control, intentions, as well as knowledge of recommended behavioral responses. Favorable attitudes and injunctive norms positively predicted intentions at the initial and delayed posttests. Importantly, the video's effects on most of the outcomes endured two weeks after video exposure. Conclusions A brief emergency preparedness video using the Run-Hide-Fight(r) theme can have immediate and lingering effects on psychosocial predictors of appropriate emergency response behaviors. Practical Applications Administrators at higher education institutions should consider showing emergency preparedness messages to increase the likelihood that stakeholders will take appropriate action in case of a campus threat. In particular, these messages should aim to promote favorable attitudes toward appropriate response behaviors and instill beliefs that appropriate responses ought to be performed.

OBJECTIVE Genomic sequencing is becoming increasingly accessible, highlighting the need to understand the social and psychological factors that drive interest in receiving testing results. These decisions may depend on perceived descriptive norms (how most others behave) and injunctive norms (what is approved of by others). We predicted that descriptive norms would be directly associated with intentions to learn genomic sequencing results, whereas injunctive norms would be associated indirectly, via attitudes. These differential associations with intentions versus attitudes were hypothesized to be strongest when individuals held ambivalent attitudes toward obtaining results. METHOD Participants enrolled in a genomic sequencing trial (n = 372) reported intentions to learn medically actionable, nonmedically actionable, and carrier sequencing results. Descriptive norms items referenced other study participants. Injunctive norms were analyzed separately for close friends and family members. Attitudes, attitudinal ambivalence, and sociodemographic covariates were also assessed. RESULTS In structural equation models, both descriptive norms and friend injunctive norms were associated with intentions to receive all sequencing results (ps < .004). Attitudes consistently mediated all friend injunctive norms-intentions associations, but not the descriptive norms-intentions associations. Attitudinal ambivalence moderated the association between friend injunctive norms (p ≤ .001), but not descriptive norms (p = .16), and attitudes. Injunctive norms were significantly associated with attitudes when ambivalence was high, but were unrelated when ambivalence was low. Results replicated for family injunctive norms. CONCLUSIONS Descriptive and injunctive norms play roles in genomic sequencing decisions. Considering mediators and moderators of these processes enhances ability to optimize use of normative information to support informed decision making. (PsycINFO Database Record

The theory of planned behavior (TPB) is a popular value-expectancy model in social and behavioral health. Motivation to comply, one of the theory's constructs, has not been well operationalized and measured in the past, and to date, there has been no assessment of whether level of specificity affects the measurement of the construct. The purpose of this study was to measure the motivation to comply construct across four domains (from general to TACT-behavior specific) and evaluate the potential impact the differences have when identifying determinants of generalized injunctive norms. Students (n = 234) attending a large southwestern university completed a TPB survey related to sleep and physical activity, and were randomized to one of four domains that measured motivation to comply (General domain, n = 58; Health domain, n = 60; Behavioral domain, n = 56; and TACT domain, n = 60). Across both behaviors, motivation to comply measurements did not appear to be affected by changing the level of specificity. Referents for sleep and physical activity were mostly significant, but the effects were small to medium. Future researchers should consider removing motivation to comply measures from TPB surveys to reduce respondent burden or find alternative ways of measuring the construct.

Increasing the uptake of pre-exposure prophylaxis (PrEP) to prevent HIV acquisition among at-risk populations, such as young men who have sex with men (YMSM), is of vital importance to slowing the HIV epidemic. Stigma and negative injunctive norms, such as the so called “Truvada Whore” phenomenon, hamper this effort. We examined the prevalence and types of PrEP stigma and injunctive norm beliefs among YMSM and transgender women and associated individual and geospatial factors. A newly created measure of PrEP Stigma and Positive Attitudes was administered to 620 participants in an ongoing longitudinal cohort study. Results indicated lower stigma among White, compared to Black and Latino participants, and among participants not identifying as male. Prior knowledge about PrEP was associated with lower stigma and higher positive attitudes. PrEP stigma had significant geospatial clustering and hotspots were identified in neighborhoods with high HIV incidence and concentration of racial minorities, whereas coldspots were identified in areas with high HIV incidence and low LGBT stigma. These results provide important information about PrEP attitudes and how PrEP stigma differs between individuals and across communities.

Background The World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) have set a Fast-Track goal to achieve 90% coverage of voluntary medical male circumcision (VMMC) among boys and men aged 10–29 years in priority settings by 2021. We aimed to identify age-specific facilitators of VMMC uptake among adolescents. Methods Younger (aged 10–14 years; n = 967) and older (aged 15–19 years; n = 559) male adolescents completed structured interviews about perceptions of and motivations for VMMC before receiving VMMC counseling at 14 service provision sites across South Africa, Tanzania, and Zimbabwe. Adjusted prevalence ratios (aPRs) were estimated using multivariable modified Poisson regression models with generalized estimating equations and robust standard errors. Results The majority of adolescents reported a strong desire for VMMC. Compared with older adolescents, younger adolescents were less likely to cite protection against human immunodeficiency virus (HIV) or other sexually transmitted infections (aPR, 0.77; 95% confidence interval [CI], .66–.91) and hygienic reasons (aPR, 0.55; 95% CI, .39–.77) as their motivation to undergo VMMC but were more likely to report being motivated by advice from others (aPR, 1.88; 95% CI, 1.54–2.29). Although most adolescents believed that undergoing VMMC was a normative behavior, younger adolescents were less likely to perceive higher descriptive norms (aPR, 0.79; .71–.89), injunctive norms (aPR, 0.86; 95% CI, .73–1.00), or anticipated stigma for being uncircumcised (aPR, 0.79; 95% CI, .68–.90). Younger adolescents were also less likely than older adolescents to correctly cite that VMMC offers men and boys partial HIV protection (aPR, 0.73; 95% CI, .65–.82). Irrespective of age, adolescents’ main concern about undergoing VMMC was pain (aPR, 0.95; 95% CI, .87–1.04). Among younger adolescents, fear of pain was negatively associated with desire for VMMC (aPR, 0.89; 95% CI, .83–.96). Conclusions Age-specific strategies are important to consider to generate sustainable demand for VMMC. Programmatic efforts should consider building on the social norms surrounding VMMC and aim to alleviate fears about pain.

We explored the potential mediating role of willingness to experience drinking consequences and other traditional alcohol outcome predictors (descriptive norms, injunctive norms, positive alcohol expectancies) in explaining the association between college alcohol beliefsThe sample consisted of 415 college students tested in October 2014.Participants responded to an online survey.When compared to both types of norms and positive alcohol expectancies, CABs demonstrated the strongest associations to both willingness to experience drinking consequences and actual drinking consequences among college students. A multiple mediation analysis revealed that the impact of CABs on students' actual drinking consequences was mediated only through their willingness to experience drinking consequences.Students' college alcohol beliefs and their corresponding willingness to experience drinking consequences should be targeted in prevention and intervention programs designed to address the problem of college student drinking.

Introduction Smoking tobacco via a waterpipe (WP) is on the rise, particularly among college students. One reason for this may be normative perceptions of WP tobacco smoking (WTS) among this population. The current study examined the perceived and actual descriptive and injunctive norms of WTS among a college student sample. Methods Participants were 894 college students enrolled at a large, Midwestern university. Participants completed measures of WTS frequency and quantity and perceived/actual descriptive and injunctive norms of WTS. Results Over one-third of the sample reported ever trying WTS, while only 2% reported current (past month) use. When comparing ever and never WP smokers, ever smokers reported greater perceived peer approval of WTS. Both males and females overestimated WTS frequency of same-sex students at their university. Discussion The current study is one of the first to investigate descriptive and injunctive norms of WTS among college students. Students who report WTS are more likely to overestimate descriptive norms of WTS among their peers, suggesting corrective normative feedback regarding actual use by peers may be an important target for WTS intervention among college students. Future research should investigate the temporal association between normative perceptions and WTS behaviors among college students.
