Network data uniquely allow relationships to be multiply reported, creating varying rates of relationship nomination reciprocation. However, what drives such variation is unclear. Variation in reciprocation may reflect substantive information about relationships (e.g., social salience or desirability) or study design (e.g., question wording or capped nominations). We examine predictors of nomination reciprocity in romantic network data from the PROSPER study to analyze individual and dyadic predictors of nomination reciprocity. Results show higher grades predict higher reciprocity, while same-sex relationships and behaviorally discordant dyads are less likely to be reciprocal.

This volume presents an overview and summary of findings from the PROSPER (Promoting School-community-university Partnerships to Enhance Resilience) Peers project, which for over a decade has sought to illuminate how adolescent friendship networks channel and facilitate the spread of developmental outcomes such as substance use, other risky behaviors, mental health problems, and educational success. In addition, it has probed the role of friendship networks in extending the impact of school and family-based prevention programs aimed at reducing substance misuse and improving adolescents’ futures. The chapters here integrate results from PROSPER Peers’ more than 50 publications along with new analyses and findings. This work was made possible by tracking the friendship networks and behaviors of thousands of students in 27 Iowa and Pennsylvania communities across middle and high school. The volume concludes with discussions by colleagues who were not involved in PROSPER Peers, and a concluding chapter focuses on the implications of this work for social capital during adolescence.

Guided by the social integration perspective, we conducted one of the first population-based studies on marital status differences in loneliness during the COVID-19 pandemic among older Americans. Analysis of data from the 2020 National Health and Aging Trends Study COVID-19 supplement (n = 2861) suggested that, compared to their married counterparts, divorced and widowed older adults reported higher levels of loneliness during the pandemic, and divorced older adults also felt lonely more often when compared to before the pandemic. These marital status differences in pandemic loneliness cannot be explained by changes in social participation (e.g., working for pay, volunteering, attending religious services, or attending clubs, classes, or other organized activities) or changes in contact frequency with family and friends (via phone calls, emails/texts/social media messages, video calls, or in-person visits). No gender difference was found in the association between marital status and loneliness during the pandemic. These results, coupled with the growth of the unmarried older population, highlight that policymakers, health care providers, and researchers should think creatively about ways to reduce the loneliness gap between married and unmarried groups to promote healthy aging for all older adults, particularly in the face of emerging pandemics that may complicate strategies to improve population health in the future.

Health status may shape network structure through network dynamics (tie formation and persistence) and direction (sent and received ties), net of typical network processes. We apply Separable Temporal Exponential Random Graph Models (STERGMs) to National Longitudinal Study of Adolescent to Adult Health survey data (n = 1,779) to differentiate how health status shapes network sent and received tie formation and persistence. Results indicate that networks are shaped by withdrawal of adolescents experiencing poor health, highlighting the importance of separating distinct and directed processes of friendship formation and persistence when considering how health relates to adolescent social life.

Substantive racial integration depends on both access to cross-race friendship opportunities (demographic integration) and the development of stable and rewarding social relations (social integration). Yet, we know little about the relative stability of cross-race friendship nominations over time. Cross-race friendships are also experienced within social contexts, where other individual, dyadic, and contextual factors may simultaneously affect whether such ties persist. Based on longitudinal network data on over 2,000 students in multiple communities, we test whether cross-race friendships are more or less stable than same-race friendships. We find that cross-race friendships at first glance appear less likely to persist than same-race friendships, but cross-race ties become no less stable than same-race ties after accounting for other social factors, including reciprocity and shared friends. This pattern suggests a threshold process where strong, socially recognized ties embedded among peers face less threat to maintaining friendship stability.

Both adolescent peer networks and adult role attainment affect mental health in adulthood. However, whether adult roles mediate associations between adolescent networks and adult mental health is unclear. Using path analysis with survey data from the National Longitudinal Study of Adolescent to Adult Health (N = 8543) in the United States, we examine the direct impact of adolescent (grades 7-12) popularity (received ties) and sociality (sent ties) among school peers on adult (ages 33-43) depressive symptoms, and we assess mediation pathways through four key adult roles: marriage, employment, education, and residential independence. We then examine whether pathways differ across men and women. Results indicate that adolescent popularity, or how others view an adolescent's position in the peer network, benefits adult mental health through the attainment of marriage, employment, and education. Residential independence is a significant mediator for popularity in models for men. Sociality, or how an adolescent views their own position in the peer network, relates to adult depressive symptoms through the attainment of a college degree for women and marriage for men. Sociality also directly predicts lower depressive levels, independent of adult role attainment, in models for women. Overall, results indicate gendered pathways for how adolescent networks relate to mental health decades later through adult roles.

Background: Childhood obesity disproportionately impacts Hispanics in the United States (US), the nation's largest ethnic minority population. However, even among Hispanic children, those born in the US are at increased risk of developing obesity than those not born in the US (i.e. first-generation Hispanics). The objective of this study is to assess whether ethnic and generational differences in the friend networks of Hispanic adolescents moderate the association between immigrant generation and weight. Methods: We analyzed data from first-generation, second-generation, and third-generation Hispanic 12 to 19 year-old participants in Wave 1 of the Longitudinal Study of Adolescent to Adult Health (Add Health). Using multivariable linear regression, we examined the association between generational status and body mass index (BMI), and whether the ethnic and generational composition of friends moderated that association. Results: Higher generational status was associated with higher BMI. The ethnic and generational composition of friends was not independently associated with BMI among Hispanic adolescents. However, a social network with a greater proportion of second-generation Hispanics was positively associated with BMI among first-generation Hispanics, and negatively associated with BMI among second-generation Hispanics. Conclusions: The generational status of peers in Hispanic adolescents' social networks, particularly the proportion that are second-generation Hispanic, moderates the positive association between immigrant generation and BMI. Moreover, this moderation effect is different across immigrant generations so that the proportion of second-generation adolescents within a social network is associated with higher BMI in first-generation Hispanic adolescents, but with lower BMI among those who are second-generation. These results were confirmed in sensitivity analyses. Our findings suggest that the generational composition of social networks alters the association between the generational status and weight of Hispanic adolescents, and thus that social factors within those networks may contribute to those associations.

Personal networks are a key component in the provision of social support for older adults. Such support is particularly critical during the COVID-19 pandemic, when traditional avenues of social engagement or assistance are disrupted. Here, we use nationally representative data from the National Social Life, Health, and Aging Project that assesses older adults’ pre-pandemic personal networks and receiving instrumental help and emotional support during the pandemic. We find that larger pre-pandemic confidant networks predict higher odds of receiving needed help and support, higher odds of receiving help and support more often than before the pandemic, and lower odds of being unable to get help. Denser pre-pandemic networks also predict higher odds of receiving instrumental help and support during the pandemic, while having a greater proportion of kin in pre-pandemic networks predicts higher odds of receiving pandemic help for non-white older adults only. Together, results suggest that features of older adults’ pre-pandemic confidant network structure and composition can provide underlying conditions for receiving social support during the pandemic.
