  • Adverse Childhood Experiences and Life Course Depressive Symptoms: Do Peer Network Ties Buffer or Amplify?

    Open Access•Christina Kamis, M Copeland•ARTICLE•Society and Mental Health•2026

    Childhood adversity affects life course mental health, but patterns may differ across adversity exposures or across social experiences that buffer or amplify risks of adversity. Using data from the National Longitudinal Study of Adolescent to Adult Health ( N = 7,597), we join the life course perspective with social networks and the stress process model to explore the relationships between adverse childhood experiences, peer networks, and depress…

  • Social network structure and composition predicting cognitive impairment: Racial/ethnic differences among older adults

    Open Access•M Copeland, Wencheng Zhang et al.•ARTICLE•The Journals of Gerontology…•2026

    Results suggest that tight-knit networks and multiple relationship types may be more supportive for cognitive health for Hispanic and Black older adults. This study contributes to research on social networks, cognitive health, and healthy aging for diverse older populations

  • Peer-friendship Networks and Self-harm among Adolescents from Inner-city Schools: A Social Network Study

    Open Access•Holly Crudgington, Rachel Blakey et al.•ARTICLE•Journal of Youth and Adolescence•2026•Cited by: 1•References: 40

    Peer-relationships are critically important for adolescent behavior, but how peer-friendship network composition and structure influence adolescent self-harm is less clear. The aim of this cross-sectional study was to explore the association between in-school peer-friendship networks, gender, and self-harm among inner-city adolescents. Participants were 2203 adolescents (mean age = 12.5 years, SD = 1.0; 53% girls) attending inner-city south Londo…

  • Gendered Social Chains of Risk: Pathways of Childhood Maltreatment, Adolescent Peer Networks, and Depressive Symptoms

    Open Access•M Copeland, Christina Kamis•ARTICLE•Journal of Health and Social…•2025•Cited by: 1•References: 49

    Childhood maltreatment is a serious stressor affecting mental health directly and indirectly through relationships, creating social chains of risk. Adolescent peers are one key relationship in the early life course, but whether peer networks mediate associations between maltreatment and mental health or if such pathways differ by gender remains unclear. We conduct path analysis on survey data from the National Longitudinal Study of Adolescent to …

  • Our Friends Keep Us Together: The Stability of Adolescents’ Cross-Race Friendships

    Open Access•B Neray, M Copeland et al.•ARTICLE•Social Forces•2023

    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 wh…

  • Associations of peer generational status on adolescent weight across Hispanic immigrant generations: A social network analysis

    Open Access•Christopher J Gonzalez, M Copeland et al.•ARTICLE•Social Science & Medicine•2023•References: 57

    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 l…

  • Embedded Distress: Social Integration, Gender, and Adolescent Depression

    Open Access•M Copeland•ARTICLE•Social Forces•2023•Cited by: 2•References: 51

    In adolescence, teens manage close friendships while simultaneously evaluating their social position in the larger peer context. Conceptualizing distinct local and global network structures clarifies how social integration relates to mental wellbeing. Examining local cohesion and global embeddedness in the context of key factors related to mental health, such as gender and friends' depression, can further distinguish when the structure and conten…

  • Who Gets Help? A National Longitudinal Study of Personal Networks and Pandemic Support Among Older Adults

    Open Access•M Copeland, Hui Liu et al.•ARTICLE•The Journals of Gerontology…•2022•Cited by: 2•References: 13

    Older adults' prepandemic confidant network structure and composition can provide underlying conditions for receiving pandemic social support. Findings speak to policies and programs that aim to foster social support or identify vulnerable groups that suffer the greatest unmet need for support during a global crisis

  • Parental Death and Mid-adulthood Depressive Symptoms: The Importance of Life Course Stage and Parent's Gender

    Open Access•Christina Kamis, Allison Stolte et al.•ARTICLE•Journal of Health and Social…•2022•Cited by: 8•References: 38

    Traditional theories of grief suggest that individuals experience short-term increases in depressive symptoms following the death of a parent. However, growing evidence indicates that effects of parental bereavement may persist. Situating the short- and long-term effects of parental death within the life course perspective, we assess the combined influence of time since loss and life course stage at bereavement on mental health for maternal and p…

  • The Long Shadow of Peers: Adolescent Networks and Young Adult Mental Health

    Open Access•M Copeland•ARTICLE•Social Sciences•2021•References: 10

    Connections with peers play an important role in adolescent mental health, but their lasting impact is unclear. This study examines whether structural status and support in adolescent networks predict depressive symptoms years later. Using data from the PROSPER Peers study (n = 1017), I find that the persistent effects of networks differ based on the mental health of teens and their friends. Structures of status and support relate to young adult …

  • The Long Arm of Social Integration: Gender, Adolescent Social Networks, and Adult Depressive Symptom Trajectories

    Open Access•Christina Kamis, M Copeland•ARTICLE•Journal of Health and Social…•2020•Cited by: 12•References: 45

    Peer connections in adolescence shape mental health in ways that differ by gender. However, it is unclear whether this association has an enduring impact on life course mental health. Using growth models with survey data from the National Longitudinal Study of Adolescent to Adult Health (Add Health Waves I-IV, N = 13,821, 51% white, 49% male), we examine how two dimensions of social integration during adolescence-popularity and sociality-predict …

  • Dynamic associations of network isolation and smoking behavior

    Open Access•M Copeland, Bryce Bartlett et al.•ARTICLE•Network Science•2017•Cited by: 10•References: 12

    Prevailing social network frameworks examine the association between peer ties and behaviors, such as smoking, but the role of social isolates is poorly understood. Some theories predict isolated adolescents are protected from peer influence that increases smoking, while others suggest isolates are more likely to initiate smoking because they lack the social control provided by peer friendships. Building on a growing literature that seeks to expl…
