Peers' Choices Influence Adolescent Risk-taking Especially When Explicit Risk Information is Lacking

This study examines the impact of peers' previous cautious versus risky choices on adolescents' risk-taking depending on the level of information about the risk. Adolescents completed an adaptation of the BART that manipulated social influence (cautious and risky) and risk information (i.e., informed, noninformed). Results showed that social influence impacts adolescents' decisions on the noninformed BART but not on the informed BART. In the noninformed BART, the peers' cautious choices strongly decreased risk-taking and led to greater performance. The peers' risky choices increase adolescents' risk-taking, but this effect is limited to situations involving minimal risk. Thus social experience may be a specific social context that represents a valuable source of information during adolescence, especially in situations with high uncertainty.

Self-Control, Opportunity, and College Students' Bystander Intervention in Sexually Coercive Situations

This study examines students' bystander intervention opportunities and behaviors using survey data from a convenience sample of 226 college students from a university in the United States. We approach this study with theoretical concepts from the criminological literature on positive peer influence, self-control theories, and social control theories. Bivariate correlations and logistic analysis reveal, contrary to our predictions, that social and self-control have only minor predictive power on the likelihood of witnessing and intervening in sexually coercive events. However, we find strong support for some demographic characteristics, peer relationships, and behavioral characteristics (such as binge drinking) as predictive of witnessing a sexually coercive event and intervening in an event. Our study adds to the literature on bystander intervention behavior and aims to inform bystander intervention programming efforts by identifying student populations that are more likely to have the opportunity to intervene in sexually coercive situations and sexual assaults.

Selection and socialization accounts of the relation between fraternity membership and sexual aggression

OBJECTIVE

The current project aims to enhance our understanding of the well-established relation between fraternity membership and sexual aggression on college campuses. Most prior research has been cross-sectional and unable to distinguish selection and socialization accounts of the relation, and only one prior longitudinal study has simultaneously examined selection and socialization effects.

METHOD

Fraternity membership, sexual aggression, binge drinking, sociosexual attitudes and behaviors, and perceived peer sexual aggression were assessed for 772 male participants (n = 116 fraternity members) in a longitudinal survey study from the summer prior to college through Year 2 of college.

RESULTS

Longitudinal path analyses revealed three key findings. First, fraternity membership was prospectively correlated with sexual aggression in Years 1 and 2 of college (socialization effect), controlling for selection effects, when the two prospective paths were constrained to be equivalent. Second, more frequent binge drinking and sociosexual attitudes prior to college prospectively correlated with an increased likelihood of joining a fraternity (selection effect), and both selection variables indirectly correlated with future sexual aggression via fraternity membership. Third, fraternity membership was associated with increased binge drinking and perceived peer sexual aggression (socialization effects).

CONCLUSIONS

These findings identify critical targets for the prevention of sexually aggressive behavior that are linked to fraternity membership: Binge drinking and sociosexual attitudes. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Peer Influence during Adolescence: The Moderating Role of Parental Support

Although many studies show that peers influence the development of adolescent internalizing and externalizing difficulties, few have considered both internalizing and externalizing difficulties in the same study, and fewer have considered the contributions of parents. Using a longitudinal sample of 385 adolescents, the contributions of best friends' internalizing and externalizing difficulties (as assessed in Grade 6; G6: M_age = 13.64 years; 53% female; 40% ethnic or racial minority) were examined as they predicted subsequent adolescent internalizing and externalizing difficulties (at G8); in addition, the moderating role of both maternal and paternal support (at G6) was explored. Structural equation modelling revealed that best friend internalizing difficulties predicted decreases, but that best friend externalizing difficulties predicted increases in adolescents' externalizing difficulties over time. Significant interactions involving both maternal and paternal support revealed that the negative impact of a G6 best friend having internalizing problems on later G8 adolescent externalizing problems was stronger at low levels of maternal and paternal support. The findings highlight the complex, and interactive, influences of friends and parents on the development of internalizing and externalizing symptomatology during adolescence, and underscore the importance of targeting both sources of social influence in research and clinical work.

Depressive Symptoms and Cigarette Smoking in Adolescents and Young Adults: Mediating Role of Friends Smoking

INTRODUCTION

We examined the mediating role of friends smoking in the association between depressive symptoms and daily/weekly cigarette smoking from adolescence into adulthood.

METHODS

Data were drawn from the Nicotine Dependence In Teens study (NDIT, Canada) and the Avon Longitudinal Study of Parents and Children (ALSPAC, UK) studies. Three age groups were investigated in NDIT: age 13-14 (n=1189), 15-16 (n=1107), and 17-18 (n=1075), and one in ALSPAC (n=4482, age 18-21). Multivariable mediation models decomposed the total effect (TE) of depressive symptoms on smoking into a natural direct effect (NDE) and natural indirect effect (NIE) through friends smoking.

RESULTS

The ORs for the TE were relatively constant over time with estimates ranging from 1.12 to 1.35. Friends smoking mediated the association between depressive symptoms and smoking in the two youngest samples (OR (95%CI) 1.09 (1.01,1.17) in 13-14-year-olds; 1.10 (1.03,1.18) in 15-16-year-olds). In the two older samples, NDE of depressive symptoms was close to the TE, suggestive that mediation was absent or too small to detect.

CONCLUSION

Friends smoking mediates the association between depressive symptoms and daily/weekly cigarette smoking in young adolescents.

IMPLICATIONS

If young adolescents use cigarettes to self-medicate depressive symptoms, then interventions targeting smoking that ignore depressive symptoms may be ineffective. Our results also underscore the importance of the influence of friends in younger adolescents, suggestive that preventive intervention should target the social environment including social relationships.

College Students' Perceptions About Prescription Drug Misuse Among Peers

BACKGROUND

Prescription drug misuse is an escalating public health problem that is prevalent among college students. Various factors, such as sex, age, race, mental health conditions, and fraternity and sorority membership, increase the risk for prescription drug misuse. Peer influences may also pose significant risks for starting prescription drug misuse, because peers are the primary source of misused prescription drugs among college students.

OBJECTIVES

To examine college students' beliefs about prescription drug misuse among their peers and to understand their beliefs about the available and potential intervention efforts to reduce prescription drug misuse.

METHOD

We conducted a cross-sectional survey of 312 college students aged 18 to 30 years who were enrolled in a large midwestern US university. The survey included questions about the responders' demographic characteristics, beliefs, and perceptions regarding prescription drug misuse among their peers and potential reduction programs for prescription drug misuse.

RESULTS

The respondents' mean age was 21 years, and most (65%) respondents were women. A majority (90%) of the respondents were enrolled in the university as full-time students. More than 60% of the respondents reported knowing someone with prescription drug misuse in the past 12 months. Fraternity or sorority members were more likely to report peer prescription drug misuse than nonmembers (83% vs 60%, respectively; P = .017). Stimulants were the most misused drug class, accounting for 75% of all reported peer prescription drug misuse. Approximately 60% of the misused prescription drugs were sourced from peers, which included friends, roommates, and classmates. A total of 73% of respondents said that prescription drug misuse was a problem among college students and 67% agreed that interventions were needed to reduce prescription drug misuse. The perceived need for interventions varied by peer prescription drug misuse. A total of 90% of students whose peers did not misuse prescription drugs said that interventions were needed, but only 67% of those with peer prescription drug misuse thought that interventions were needed.

CONCLUSION

Our findings indicate that peer prescription drug misuse is very common among college students, and the most misused drug class is stimulants. Survey respondents perceived that the current interventions used to address prescription drug misuse are not very effective or may not be targeting the right population. Peer prescription drug misuse influences college students' perceptions about the risks and harms of prescription drug misuse, as well as the need for interventions.

Social Support and Peer Group Integration of Adolescents with Diabetes

The aim of this study was to examine, through the roles of peers with regards to diabetes, the relationship between the support perceived by adolescents with diabetes and their peer-group affiliation. This is a descriptive, phenomenological and retrospective study based on a qualitative methodology. In-depth interviews with 15 people aged 18-35 with type 1 diabetes mellitus diagnosed in their childhood or adolescence were carried out. Data was analyzed through the interpretation of general discourses. Peers have considerable influence on adolescents and provide them social support from different roles. The protective role basically offers emotional support and sends reminders of different aspects of the treatment, while the indifferent role does not meddle in any aspect related to the diabetes. Both roles can foster social integration of adolescents with diabetes into the peer group. The offender role creates social conflicts through discrimination and stigma of adolescents with diabetes. These roles appear during the process of socialization of adolescents with diabetes, where commensality and situations of self-monitoring or administering insulin, key aspect of diabetes treatment, are crucial. Peer groups, depending on the role adopted, may offer support or bring a specific conflict regarding diabetes to their adolescent peer. The combination of roles that friends and peer group play with regards to diabetes will determine the degree of socialization and integration of adolescents with diabetes.

Peer Influence on IPV by Young Adult Males: Investigating the Case for a Social Norms Approach

Nearly 32% of women report experiencing physical violence from an intimate partner and more than 8% report being raped by a significant other in their lifetime. Young people's perceptions that their peers perpetrate relationship violence have been shown to increase the odds of self-reported perpetration. Yet, limited research has been conducted on this relationship as individuals begin to age out of adolescence. The present study sought to examine the link between the perception of peer perpetration of intimate partner violence (IPV) and self-reported IPV perpetration among a sample of predominately young adult (21-35 years) males. This study also explored the discordance between the perception of peer IPV behavior and self-reported perpetration. Data from 101 male peer dyads (n = 202) were taken from a study on the effects of alcohol and bystander intervention in Atlanta, Georgia. Thirty-six percent (n = 73) of men reported perpetrating physical IPV and 67% (n = 135) reported perpetrating sexual IPV in the past 12 months. Nearly 35% (n = 55) of the sample reported that none of their peers had perpetrated physical IPV, which contradicted their friend's self-report of physical IPV perpetration. Similarly, 68% (n = 115) of the men perceived none of their peers to have perpetrated sexual IPV, which contradicted their friend's self-report of sexual IPV perpetration. Discordance variables were significantly associated with self-reported perpetration for both physical (χ² = 152.7, p < .01) and sexual (χ² = 164.4, p < .01) IPV. These results point to an underestimation of peer IPV perpetration among young adult males. Findings suggest a traditional social norms approach to IPV prevention, which seeks to persuade individuals that negative behaviors are less common than perceived, may not be the best approach given a significant number of men believed their friends were nonviolent when they had perpetrated violence.

llicit Drug Use among College Students: The Importance of Knowledge about Drugs, Live at Home and Peer Influence

The problem of consumption of illicit psychoactive substances by students in higher education is not new, since it is in this age group that the highest prevalence of consumption of these substances continues to occur. This study aimed to describe the prevalence of illicit drug use among university students and to analyze the predictive factors and patterns of illicit drug use among university students in Portugal. A cross-sectional design and a stratified random sampling method were used (n = 840). A validated self-administered questionnaire was used, consisting of socio-demographic characteristics, information about the patterns of illicit drugs consumption, and knowledge and attitudes toward illicit drugs use. The prevalence of illicit drugs consumption was 22.2%, while overall students had a low level of knowledge and moderate scores when it came to the attitudes toward drug use. Being male, having changed residence after entering higher education, having friends who use illicit drugs and possessing knowledge on drugs increased the likelihood of consuming illicit drugs. The results of the study could help develop strategies to reduce use of illicit drugs in academic settings, giving special attention to the influence of peers and students who changed their residence after entering higher education.

Gender Differences in the Interest in Mathematics Schoolwork Across 50 Countries

Although much research has found girls to be less interested in mathematics than boys are, there are many countries in which the opposite holds. I hypothesize that variation in gender differences in interest are driven by a complex process in which national culture promoting high math achievement drives down interest in math schoolwork, with the effect being amplified among girls due to their higher conformity to peer influence. Predictions from this theory were tested in a study of data on more than 500,000 grade 8 students in 50 countries from the 2011 and 2015 waves of TIMSS. Consistent with predictions, national achievement levels were strongly negatively correlated with national levels of math schoolwork interest and this variation was larger among girls: girls in low-achievement, high-interest countries had especially high interest in math schoolwork, whereas girls in high-achievement, low-interest countries had especially low interest in math schoolwork. Gender differences in math schoolwork interest were also found to be related to gender differences in math achievement, emphasizing the importance of understanding them better.

Valuation of peers' safe choices is associated with substance-naïveté in adolescents

Social influences on decision-making are particularly pronounced during adolescence and have both protective and detrimental effects. To evaluate how responsiveness to social signals may be linked to substance use in adolescents, we used functional neuroimaging and a gambling task in which adolescents who have and have not used substances (substance-exposed and substance-naïve, respectively) made choices alone and after observing peers' decisions. Using quantitative model-based analyses, we identify behavioral and neural evidence that observing others' safe choices increases the subjective value and selection of safe options for substance-naïve relative to substance-exposed adolescents. Moreover, the effects of observing others' risky choices do not vary by substance exposure. These results provide neurobehavioral evidence for a role of positive peers (here, those who make safer choices) in guiding adolescent real-world risky decision-making.

Effects of a Self-efficacy Theory-Based Training Program for Peers of Patients with Type 2 Diabetes

Background

Training peer leaders to deliver patient education is expected to be a low-cost approach to providing healthcare in urban-poor areas affected by a shortage of healthcare professionals. The purpose of this study was to examine the effects of a training program on the self-efficacy and knowledge of peer leaders with type 2 diabetes.

Methods

A single-group longitudinal survey with baseline, intervention, and follow-up periods was conducted at a diabetes clinic in a small municipality in Metro Manila, Philippines. The intervention, a self-efficacy theory-based training program for peer-leaders of diabetic patients conducted in August 2017, comprised hands-on learning, demonstrations, quizzes, role-playing, group sharing, physical exercise, and a buffet lunch. The primary outcome was participants' self-efficacy for management of their diabetes. Secondary outcomes were participants' knowledge of diabetes and levels of emotional distress, motivation, and confidence for guiding their peers, satisfaction with the training program, hemoglobin A1c, and quality of life.

Results

At 12 and 18 months after the intervention, participants' knowledge of diabetes was significantly increased compared with baseline (both P < 0.05). At earlier time points, an increasing, but not significant, trend was observed. The change in knowledge of diabetes from baseline to 18 months after intervention tended to be positively correlated with the change in self-efficacy (r = 0.594, P = 0.054). No significant differences were observed for any of the other outcomes, although the descriptive statistics showed an increasing trend for all of the outcomes except motivation.

Conclusion

The training program significantly improved participants' knowledge of diabetes at 12 and 18 months after the training programs compared with baseline. A positive correlation between the changes in the levels of knowledge and self-efficacy suggested that the observed improvement of self-efficacy was facilitated by the improvement of knowledge of diabetes.

Usability and Acceptability of a Mobile App to Help Emerging Adults Address their Friends' Substance Use (Harbor): Quantitative Study

BACKGROUND

Technology-assisted intervention and prevention strategies present opportunities for substance use-related research with emerging adults (EAs) and their peers. Emerging adulthood is a developmentally distinct period in which individuals between the ages of 18 and 29 years undergo unique emotional, cultural, developmental, and biological changes as they transition into adulthood. Crowdsourcing, or gathering feedback from a large group within web-based communities, offers researchers a unique and cost-effective way to obtain large amounts of information in a short period.

OBJECTIVE

This paper presents market feedback obtained via Amazon's Mechanical Turk from EAs (N=458) on the acceptability and utility of brief intervention scripts for a smartphone app currently under development. The mobile app, Harbor, teaches friends of EAs with substance use problems effective and supportive strategies for helping their friend make changes in their substance use behavior.

METHODS

We examined feedback on the wording of the intervention scripts and estimated the market size of EAs who may use this app. Furthermore, we calculated correlations between script ratings and measures of personal risky drinking (ie, Alcohol Use Disorder Identification Test) and the participants' use of confrontational, enabling, or supportive behaviors with an existing friend.

RESULTS

Approximately half of our sample (208/458, 45.4%) indicated that they had a close friend for whom they had concerns about their substance use, suggesting a potentially high demand for an app such as Harbor. Initial findings suggest that peers who engage in less enabling behaviors with friends who have a substance use problem exhibited lower risky drinking behaviors overall (r₂₀₆=-0.501; P<.001). Concerning acceptability, 98.0% (449/458) of the sample rated the scripts' dialogue as either somewhat, moderately, or extremely realistic (mean 3.92, SD 0.48) on 5-point Likert scale items. Finally, 95.4% (437/454) of respondents indicated that the scripts would be at least slightly helpful for training peers to help their friends with substance use issues. Finally, individuals who were better able to identify enabling language in enabling scripts self-reported fewer enabling behaviors toward their friend's substance use (r₂₀₆=-0.236; P=.001).

CONCLUSIONS

There exists a demonstrated level of desirability and acceptability among EAs for a mobile app such as Harbor. EAs who wish to engage in more supportive behaviors with their friends who engage in substance use and who are amenable to assisting their friends with sobriety likely would use and benefit from this app.

The Sources of Belief in Personal Capability: Antecedents of Self-Efficacy in Private Adaptation to Flood Risk

Self-efficacy is one of the strongest and most consistent drivers of private flood mitigation behavior; however, the factors influencing self-efficacy in the context of flooding remain unclear. The present study examines three potential antecedents of self-efficacy: personal and vicarious experiences of floods or building-related events, social norms for private flood preparedness, and personal competencies such as technical abilities and social skills. While controlling for other drivers in a protection motivation theory (PMT) framework, these antecedents are tested as precursors of self-efficacy and intentions to improve flood resilience. Structural equation modeling is applied to conduct mediation analyses with survey data of 381 flood-prone households in Austria. Contrary to theoretical expectations, personal and vicarious experiences do not predict self-efficacy, presumably because rare flood events and changing hazard characteristics do not facilitate generalizable performance accomplishments. Social norms strongly and consistently influence self-efficacy, especially for actions observable by others, and also directly influence protective responses. Personal competencies increase self-efficacy and support protective action, particularly with regard to preventive and structural measures. The strength and direction of the antecedents of self-efficacy as well as of other PMT determinants vary between general and specific protective responses. This study provides important insights for risk managers, suggesting that interventions involving social norms and personal competencies can be effective in stimulating self-efficacy and, in turn, private flood mitigation. Interventions and research should clearly differentiate between general intention and the implementation of specific measures, and should address cumulative, synergistic, or tradeoff interrelations between multiple measures.

The Supporting Role of Mentees' Peers in Online Mentoring: A Longitudinal Social Network Analysis of Peer Influence

Studies show that online mentoring is an effective measure to support girls in STEM (science, technology, engineering, and mathematics), especially if it also allows for networking with other participants on the mentoring platform. However, research is missing on peer influence. This topic seems especially crucial in programs for adolescents as peer influence plays an important role at this age. In our study, we investigated peer influence on mentoring outcomes - confidence in own STEM abilities and STEM-related activities - in an online mentoring program in STEM for secondary school girls (N = 124, M = 14.3 years, SD = 2.2 years, age range: 11-19 years). The program provides girls with at least 1 year of one-on-one interaction with a personal female mentor who has a college degree in a STEM subject. Participants can also interact with other participants on the platform. We used a longitudinal social network analysis approach to examine peer influence on mentoring outcomes. Our results indicate that both mentoring outcomes - mentees' confidence in own STEM abilities and STEM-related activities - are influenced by peers moderated by the mentees' own age. Younger mentees tended to become more similar to their peers regarding confidence in own STEM abilities and STEM-related activities, whereas older mentees tended to become more dissimilar over time. In addition, peer group size had a positive effect on confidence in own STEM abilities, but not on STEM-related activities. This effect was moderated by the mentee's age. Overall, peers have a positive influence on the measured mentoring outcomes, especially for young mentees.

Peer Influence in Adolescence: Public-Health Implications for COVID-19

The coronavirus disease 2019 (COVID-19) pandemic has resulted in the widespread implementation of social distancing measures. Adhering to social distancing may be particularly challenging for adolescents, for whom interaction with peers is especially important. We argue that young people's capacity to encourage each other to observe social distancing rules should be harnessed.

Facilitators and barriers to completing recommended doses of pneumococcal vaccination among community-living individuals aged ≥65 years in Hong Kong - a population-based study

Individuals aged ≥65 y are recommended to receive pneumococcal vaccination (PV). PV completion is defined as receiving two doses of PV among those with at least one high-risk condition for severe invasive pneumococcal diseases (IPD) or receiving one dose of PV among those without any high-risk conditions. This study investigated factors associated with PV completion among a random sample of community-living older adults in Hong Kong, China. In addition, factors associated with receiving a single dose of PV among older adults with at least one high-risk condition were also investigated. A total of 750 community-living Chinese-speaking individuals aged ≥65 y in Hong Kong (response rate: 63.4%) completed a random telephone survey from May to July 2019. PV completion was 10% among all participants. Among participants with high-risk condition(s) for severe IPD, 11.4% received a single dose of PV. After adjustment for significant background variables, several Health Belief Model constructs were significantly associated with both dependent variables: (1) perceived risk of contracting pneumococcal diseases, (2) perceived benefits of PV for protecting themselves or others, (3) perceived barriers to PV uptake, (4) being suggested by significant others to take up PV (cue to action), and (5) confidence to take up PV (perceived self-efficacy). In addition, being knowledgeable about pneumococcal diseases and vaccination, and knowing at least one peer of similar age who had taken up PV were also positively associated with both dependent variables. Targeted, theory-based health promotion efforts are needed to increase PV coverage among elderly in Hong Kong.

Impacts of Men's Gender-transformative Personal Narratives: A Qualitative Evaluation of the Men's Story Project

Gender-transformative interventions have been found to help ameliorate gender-inequitable norms and improve health outcomes for women and men. While narrative-based strategies are increasingly being used in public health programs, no evaluation publications exist to date for gender-transformative programming that employs men's public narrative-sharing as a central means for promoting healthy masculinities. The Men's Story Project (MSP) creates live productions in which diverse men publicly perform personal narratives that challenge hegemonic masculinity, promote gender equality, and highlight intersections of masculinity with other social identities. This study draws upon six focus groups with thirty-one audience members (AMs), two weeks after an MSP production at a US public university. The MSP led AMs to reevaluate key pillars of hegemonic masculinity, including a singular conception of masculinity, essentialist notions of gender, restricted emotional expression, and use of violence; AMs also gained an expanded understanding of intersectionality. Directions for future research are discussed.

Age-varying associations between e-cigarette use and peer use, household use, and exposure to e-cigarette commercials among alternative high school students in Southern California

INTRODUCTION

Electronic cigarettes (e-cigarettes) have rapidly become the most commonly used tobacco product among youth in the United States. Exposure to advertising, peer use, and household use, increases the risk of current e-cigarette use; however, the influence of these factors may be dynamic across adolescence. The aim of this study is to examine the age-varying associations between e-cigarette use and peer use, household use, and exposure to e-cigarette commercials among alternative high school students in Southern California.

METHODS

Using data previously collected for a tobacco marketing study, we examine the age-varying associations of current e-cigarette use and three risk factors (peer use, exposure to commercials, and household use) across ages 15 to 20 years using time-varying effect modeling (TVEM). Analyses include three waves of data from alternative high school students (N=1060 students; 2036 observations).

RESULTS

The probability of e-cigarette use gradually increased over the age of 15 years and then decreased by the age of 17 years for females and after the age of 18 years for males. Significant gender differences were observed between the ages of 17 and 19.5 years. Peer e-cigarette use was associated with higher odds of current e-cigarette use across all ages for females and after the age of 16 years for males. Exposure to e-cigarette commercials increased current use significantly for males between the ages of 16 and 18 years. Household use increased the odds of current use of e-cigarettes between the ages of 17 and 19 years for males and under 16.5 and over 18 years for females.

CONCLUSIONS

The findings highlight the utility of TVEM in understanding the risk factors of e-cigarette use and suggest that these factors are dynamic across adolescence.

The Association between Psychopathy and Influencing Others to Use Substances

Background: Although a large body of research has examined the impact of peer influence on substance use, little is known about the psychology of who influences others to use substances and why. The Dark Triad is a set of personality traits that may inform the characteristics of people who influence others to use substances.Objective: The aim of the present two studies was to examine potential associations between Dark Triad personality traits, especially psychopathy, and influencing others to use substances.Methods: Two samples of 162 and 161 Mechanical Turk workers were recruited for Study 1 to complete an online survey that assessed Dark Triad traits, history of influencing others to use substances, and motivations for doing so. Similarly, 303 Mechanical Turk workers were recruited for Study 2 to complete an online survey that assessed personal substance use as well as psychopathy levels of participants' closest friends.Results: Study 1 found that individuals high in psychopathy were more likely to have provided illegal substances to others and indicated a willingness to do so in the future. Study 2 found that participants reported a higher likelihood of using substances if they indicated that their best friend was high in psychopathy and had themselves used substances in the past.Conclusions: Taken together, these findings suggest that psychopathy has a unique association with influencing others to use substances. These findings have implications for intervention targets.

The Interaction of Smoking Cessation Norms and Nicotine Dependence on Quit Attempts: Gender-Stratified Results for Low-Income Smokers in Baltimore, MD

Background: Declines in smoking prevalence among low-income adults lag behind national samples. Understanding the influence of social context factors such as gender, and normative influence on smoking attitudes and behaviors, can inform smoking cessation interventions. Objective: This study explored how gender, smoking dependence, and cessation norms influenced the likelihood of current quit attempts among urban-dwelling, predominately African American adults. Methods: Participants answered questions about their current quit attempts, smoking dependence (heaviness of smoking index [HSI]), and cessation norms (descriptive: having friends who quit smoking; injunctive: friends disapproving of smoking) as a part of a parent study exploring social and environmental factors in tobacco use. Logistic regression stratifying by gender and adjusting for demographics examined main and interaction effects of norms and HSI on odds of having a current quit attempt. Results: Among men, having a higher smoking dependence was associated with a reduced likelihood of trying to quit (AOR = 0.30 [0.15-0.59]), but this effect was moderated by having friends who had quit smoking (AOR = 2.40 [1.20-4.78]). When accounting for the effect of friends quitting smoking, men were not influenced by friends disapproving of smoking. Among women, currently attempting to quit was predicted by neither smoking dependence nor norms. Conclusions/Importance: Cessation norms and smoking dependence influenced the likelihood of quit attempts for men, but not women, in this study. This highlights the importance of conducting gender stratification in smoking cessation research so as to better understand how social and environmental factors differently impact cessation outcomes for men and women.

Preliminary Findings of the Links Between Gender Role Attitudes and Sexual Behaviors in Mexican American Early Adolescent Boys

This study explored the relations between Latino gender role attitudes (traditional machismo attitudes and caballerismo attitudes) and sexual behaviors among 242 Mexican American early adolescent boys in the southwest United States. Specifically, a multiple mediator model estimated the association between gender role attitudes and sexual activity through a mediational pathway connecting substance use, sexual motives, and peer influence. Results from analyzing this structural equation model indicated that traditional machismo attitudes were not associated with sexual behaviors. Caballerismo gender role attitudes, however, were indirectly linked with reduced sexual motives and substance via peer influence. This study underscores the importance of social context, behavior, and psychological motivations in explaining differences in sexual motives and substance use among young Mexican American adolescent boys who hold different kinds of beliefs about their gender.

Peer Mentorship via Mobile Phones for Newly Diagnosed HIV-Positive Youths in Clinic Care in Khayelitsha, South Africa: Mixed Methods Study

BACKGROUND

Youths in South Africa are poor utilizers of HIV health services. Medecins Sans Frontieres has been piloting youth-adapted services at a youth clinic in Khayelitsha, including a peer virtual mentorship program over mobile phones, piloted from March 2015 to May 2016.

OBJECTIVE

The objective of this study was to evaluate the effect of the peer mentorship program on youth engagement with HIV services and explore the acceptability of the program to both mentors and mentees.

METHODS

Antiretroviral initiation, retention in care (RIC), and viral load suppression were compared between youths engaged in the virtual mentorship program and two matched controls. In-depth interviews were also conducted for 5 mentors and 5 mentees to explore acceptability and impact of the program.

RESULTS

A total of 40 youths were recruited into the virtual mentorship program over the study period. Of these, data were obtained for 35 and 2 matched controls were randomly sampled for each. There was no difference in baseline demographics (eg, age, gender, and CD4 count). Mentees had increased antiretroviral initiation (28/35, 80% vs 30/70, 42% in matched controls) and viral load completion (28/35, 80% vs 32/70, 45%); however, no differences were found in viral load suppression or RIC at 6 or 12 months. Mentors reported being motivated to participate in the program because of previous personal struggles with HIV and a desire to help their peers. Mentees reported fears of disclosure and lack of acceptance of their status as barrier to accessing services, but they felt free to talk to their mentors, valued the mentorship program, and indicated a preference for phone calls.

CONCLUSIONS

Peer mentorship in youths is acceptable to both mentors and mentees and appears to increase linkage to care and viral load completion rates.

Beyond deviancy-training: Deviant adolescent friendships and long-term social development

Adolescent association with deviant and delinquent friends was examined for its roots in coercive parent-teen interactions and its links to functional difficulties extending beyond delinquent behavior and into adulthood. A community sample of 184 adolescents was followed from age 13 to age 27, with collateral data obtained from close friends, classmates, and parents. Even after accounting for adolescent levels of delinquent and deviant behavior, association with deviant friends was predicted by coercive parent-teen interactions and then linked to declining functioning with peers during adolescence and greater internalizing and externalizing symptoms and poorer overall adjustment in adulthood. Results are interpreted as suggesting that association with deviant friends may disrupt a core developmental task-establishing positive relationships with peers-with implications that extend well beyond deviancy-training effects.

Conceptions of Adolescent Friendship Quality in Sport and Music Domains

Purpose: The purposes of the present study were to (a) compare context-specific conceptions of friendship quality in youth sport and music, and (b) determine how friendship quality is related to motivational beliefs in sport and music. Method: Adolescents (N = 366; M_age = 12.9, SD = 1.0) who were involved in both organized sport and music completed measures of domain-specific friendship quality, perceived competence, enjoyment, anxiety, and motivational orientation. Results: For purpose one, a repeated-measures MANOVA revealed that (a) boys and girls rated their best sport friends higher in self-esteem enhancement and supportiveness than their best music friends, (b) boys rated their best sport friends higher in loyalty and intimacy, things in common, companionship and pleasant play, and conflict resolution than their best music friends, (c) girls rated positive friendship quality dimensions higher than boys, and (d) there were no domain or gender differences in friendship conflict. For purpose two, structural equation modeling revealed that (a) for sport, positive friendship quality dimensions were directly associated with perceived competence and indirectly associated with enjoyment, anxiety, and motivational orientation, and (b) for music, positive friendship quality and friendship conflict were related to competence motivation variables. Conclusion: Collectively, findings indicate domain differences in friendship quality and the relationship between friendship quality and motivational outcomes in sport and music. Despite some domain differences, findings demonstrate the significance of friendship quality for adolescents involved in sport and music.
