Objective Social connectedness is a modifiable lifestyle factor that delays age-related cognitive decline. Using cross-sectional, longitudinal, and experimental approaches, we examined whether theory of mind – inferring what others think or feel – is a potential mechanism underlying this relationship. Methods In Study 1, 305 community-dwelling old...

The mechanisms by which older adults maintain large, complex social networks are not well understood. Prior work has primarily focused on general cognitive ability (e.g., executive function, episodic memory), largely overlooking social cognition—the ability to process, store, and remember social information. Because social cognition plays a key rol...

Substantial research has focused on how social networks help individuals navigate the illness experience. Sociologists have begun to theorize beyond the binary of strong and weak social network ties (e.g., compartmental, elastic, and disposable ties), citing the social, economic, and health conditions that shape their formation. However, limited re...

Background Social connectedness is associated with better cognitive performance among older adults. Previously, we found that bridging (access to an expansive network of diverse and loosely connected individuals) and bonding (close and supportive relationships to familiar others) associated with preserved gray matter density (GMD). We sought to exa...

We sought to exa...

INTRODUCTION Social connectedness is associated with slower cognitive decline among older adults. Recent research suggests that distinct aspects of social networks may have differential effects on cognitive resilience, but few studies analyze brain structure. METHODS This study includes 117 cognitively impaired and 59 unimpaired older adults. The...

Problem opioid use and opioid-related drug overdoses remain a major public health concern despite attempts to reduce and monitor opioid prescriptions and increase access to office-based opioid treatment. Current provider-focused interventions are implemented at the federal, state, regional, and local levels but have not slowed the epidemic. Certain...

Objective: To characterize hospital-level professional networks of physicians caring for older trauma patients as a function of trauma patient age distribution. Summary background data: The causal factors associated with between-hospital variation in geriatric trauma outcomes are poorly understood. Variation in physician practice patterns reflec...

Individuals with more complex jobs experience better cognitive function in old age and a lower risk of dementia, yet complexity has multiple dimensions. Drawing on the Social Networks in Alzheimer Disease study, we examine the association between occupational complexity and cognition in a sample of older adults (N = 355). A standard deviation (SD)...

The social network perspective has great potential for advancing knowledge of social mechanisms in many fields. However, collecting egocentric (i.e., personal) network data is costly and places a heavy burden on respondents. This is especially true of the task used to elicit information on ties between network members (i.e., alter-alter ties or den...

Social connectedness has been linked to decreased rates of cognitive decline particularly among older adults (Fratiglioni et al., 2004). Several studies have demonstrated that access to an expansive network of diverse, and loosely connected individuals (i.e., social bridging) plays a particularly unique role in conferring resilience against cogniti...

Ambivalent ties are relationships that offer support but beget stress, which generally has a detrimental impact on health. Existing theory suggests that older adults gradually remove such ties over time; however, it is not uncommon for ambivalence to exist in older adults’ close relationships (i.e., partners, children). Social network data was used...

Social connectedness confers benefits to older adults’ cognition, including slowing the progression of Alzheimer’s disease (AD). Social connectedness is facilitated by social cognitive function – how people understand, store, and apply information about others – which declines over the lifespan. We examined whether two core social cognitive skills...

There is a critical need to grow and strengthen the pipeline of physician scientists who have expertise in sociomedical and behavioral research and are dedicated to addressing the nation's challenges posed by Alzheimer's disease and related dementias (ADRD). In 2021 The Indiana ADRD Medical Scientist Training Program (IADRD MSTP) was designed to me...

This presentation will describe a series of research projects using Social Network Analysis (SNA) to measure the personal social networks of community-dwelling older adults at-risk for or currently experiencing dementia. The first part of the presentation will provide a brief overview of SNA methods, including advantages of SNA compared to more tra...

Social connectedness has been linked to decreased rates of cognitive decline in later life. However, recent work suggests that particular social network characteristics (i.e., bonding and bridging) may buffer against age-related degeneration. The present study analyzes social network and structural MRI data of 176 older adults from the Social Netwo...

The link between social connectedness and dementia risk and resilience has been examined using a diverse set of measures. Though different measures of connectedness reflect distinct social processes and underlying mechanisms (e.g., stress buffering, cognitive stimulation), few studies have compared them. Using data from two social network studies o...

Social connectedness has been linked to decreased rates of cognitive decline particularly among older adults (Fratiglioni et al., 2004). Several studies have demonstrated that access to an expansive network of diverse, and loosely connected individuals (i.e., social bridging) plays a particularly unique role in conferring resilience against cogniti...

Visiting multiple prescribers is a common method for obtaining prescription opioids for nonmedical use and has played an important role in fueling the United States opioid epidemic, leading to increased drug use disorder and overdose. Recent studies show that centrality of the bipartite network formed by prescription ties between patients and presc...

When the coronavirus emerged in early 2020, older adults were at heightened risk of contracting the virus, and of suffering mental health consequences from the pandemic and from the precautions designed to mitigate it. In this paper, we examine how social networks prior to the pandemic helped to shape health beliefs, behaviors, and outcomes among o...

Objectives: While organ-specific pathophysiology has been well-described in SARS-CoV-2 infection, less is known about the attendant effects on functional status, mood state and leisure-time physical activity (PA) in post-acute COVID-19 syndrome (PASC). Methods: A case-control design was employed to recruit 32 women (n = 17 SARS-CoV-2; n = 15 contro...

Drug-related overdose deaths topped 100,000 between 2020 and 2021. Opioids and stimulants are implicated as the primary drivers of this public health crisis. Stigma remains one of the primary barriers to treatment and recovery from substance use disorders. However, little is known about how stigma varies across different substance types, whether in...

Widespread uptake of vaccines is necessary to achieve herd immunity. However, uptake rates have varied across U.S. states during the first six months of the COVID-19 vaccination program. Misbeliefs may play an important role in vaccine hesitancy, and there is a need to understand relationships between misinformation, beliefs, behaviors, and health...

A large literature highlights the link between cognitive function and social networks in later life. Yet there remains uncertainty about the factors driving this relationship. In the present study, we use measures of subjective cognitive decline and clinical cognitive assessments on a sample of older adults to investigate whether the relationship b...

One of the most promising directions for reducing mental illness stigma lies in Allport’s contact theory, which suggests that intergroup interactions reduce stigma. Here, we argue that stigmatizing attitudes are driven by the nature, magnitude, and valence of community-based ties to people with mental illness (PMI), not simply their presence. Using...

Cognitively stimulating environments are thought to be protective of cognitive decline and onset of Alzheimer's disease and related dementias (ADRD) through the development of cognitive reserve (CR). CR refers to cognitive adaptability that buffers the impact of brain pathology on cognitive function. Despite the critical need to identify cognitivel...

Objectives: While organ-specific pathophysiology has been well-described in SARS-CoV-2 infection, less is known about the attendant effects on functional status, mood state and leisure-time physical activity (PA) in post-acute COVID-19 syndrome. Methods: A case-control design was employed to recruit 32 women (n = 17 SARS-CoV-2; n = 15 controls) mat...

Personal social networks play a fundamental role in the daily lives of older adults. Although many studies examine how life course factors and personal preferences shape network formation, fewer consider how the places in which older adults live present opportunities and obstacles to cultivate social relationships. In the present study, we explore...

Background and Objectives Substantial evidence links social connectedness prospectively to cognitive aging outcomes, but there is little agreement about the social processes or mechanisms that drive this relationship. This study evaluated nine measures of social connectedness, focusing on two distinct forms of social enrichment – access to an expan...

Importance During the pandemic, access to medical care unrelated to COVID-19 was limited because of concerns about viral spread and corresponding policies. It is critical to assess how these conditions affected modes of pain treatment, given the addiction risks of prescription opioids. Objective To assess the trends in opioid prescription and nonp...

Evidence supports Allport's (1954) contention that social contact reduces mental illness stigma and promotes symptom recognition. However, an important limitation of existing research is that it typically relies on relatively simplistic measures of contact (e.g., any contact, number of contacts). Here, we build on prior work by examining how contac...

Access to cognitive stimulation through social interactions is a key mechanism used to explain the association between personal networks, cognitive health, and brain structure in older adults. However, little research has assessed how best to operationalize access to novel or diverse social stimuli using social network measures, many of which were...

Objective The cognitive reserve hypothesis has been proposed as a key mechanism explaining the link between social networks and cognitive function but has rarely been empirically tested using neuroimaging data. This study examines whether social network attributes moderate the association between amygdalar volume and cognitive function. Methods Da...

Georg Simmel (1858-1918) is widely recognized as an important forerunner of the social network approach. This chapter discusses the impact of Simmel’s writings on the develop-ment of social network analysis and its relevance for contemporary research. I argue that Simmel’s work was both more influential and more systematic than has usually been ack...

NetLab’s four East York studies in Toronto have traversed from the Community Question—how have structural shifts in society affected personal networks—to the Network Question—how have information and communication technologies (ICTs) affected the nature of these networks? Where doom-pundits had asserted that community has withered, the first two st...

A reflection on J. Clyde Mitchell’s (1969) classic piece “The concept and use of social networks”. In the piece, Mitchell lays out the “known world” of social network analysis, discussing fundamental concepts, theory and methods. Looked at 50 years later, we see much that is core to how we think about networks today, but we also see some difference...

Festinger, Schachter, and Back’s Social Pressures in Informal Groups (henceforward FSB’s SPIG) was one of the most exciting and theoretically generative works in what we now think of as the field of social networks, emerging from one of the focal arenas of Gestalt-psychology-inspired research. It established the importance of functional distance fo...

Social networks are ubiquitous. The science of networks has shaped how researchers and society understand the spread of disease, the precursors of loneliness, the rise of protest movements, the causes of social inequality, the influence of social media, and much more. Egocentric analysis conceives of each individual, or ego, as embedded in a person...

In their influential chapter on the boundary specification problem in network analysis, Laumann, Marsden, and Prensky (1989) argued that social network data often do not mirror the true underlying social structures in which individuals are embedded. Rather, the validity of network data hinges on the alignment of network boundaries and the social sy...

Homophily is the higher probability of connection between similar as opposed to dissimilar entities. It is a property of social systems. It is not a synonym for “similarity” or “interpersonal liking for similar others.” In this chapter, we review the steady growth in the homophily literature citing “Birds of a Feather Flock Together“ (McPherson, Sm...

This is an overview of the foundation for, and substance of, emerging research on network broker behavior, research that constitutes a second generation of work on network brokerage. I begin with a capstone of key past results along with my cautions and enthusiasms about directions in which things are going. I discuss the information breadth, timin...

This quality improvement study assesses the comorbidities associated with COVID-19 diagnostic codes in US health insurance claims.

Research suggests social connectedness may help older adults with dementia maintain cognitive functionality and quality of life. However, little is known about its specific social and biological mechanisms. This paper proposes two pathways through social bridging (i.e., cognitive enrichment through expansive social networks) and bonding (i.e., neur...

Background and objectives: Social connectedness has been linked prospectively to cognitive aging, but there is little agreement about the social mechanisms driving this relationship. This study evaluated nine measures of social connectedness, focusing on two forms of social enrichment - access to an expansive and diverse set of loosely connected i...

BACKGROUND Widespread uptake of vaccines is necessary to achieve herd immunity. However, uptake rates varied across U.S. states during the first six months of the COVID-19 vaccination program. Online misinformation may play an important role in vaccine hesitancy, and there is a need to comprehensively quantify the impact of misinformation on belief...

Background The efficacy of testing and tracing programs to reduce COVID-19 transmission hinges not only on widespread access to testing, but also on the public’s willingness to participate in them. To the extent that testing intentions are patterned by social determinants of health, this constitutes an understudied mechanism of disparities in COVID...

Background and aims: Prescription drug seeking (PDS) from multiple prescribers is a primary means of obtaining prescription opioids; however, PDS behavior has likely evolved in response to policy shifts, and there is little agreement about how to operationalize it. We systematically compared the performance of traditional and novel PDS indicators....

Although many studies examine how life course factors and personal preferences shape network formation, fewer consider how the places in which older adults live present opportunities and obstacles to cultivate social relationships. In the present study, we explo...

Widespread uptake of COVID-19 vaccines is necessary to achieve herd immunity. However, surveys have found concerning numbers of U.S. adults hesitant or unwilling to be vaccinated. Online misinformation may play an important role in vaccine hesitancy, but we lack a clear picture of the extent to which it will impact vaccination uptake. Here, we stud...

Objective The current study explores whether personal social network characteristics are associated with older adults’ memory and/or social cognitive function (e.g., ability to infer other’s mental states – theory of mind). Methods 120 older adults completed a social network interview, a memory measure, and two core measures of social cognitive fu...

Significance The 2008 Great Recession widened socioeconomic inequities among young adults, people of color, and those without a college degree. The COVID-19 pandemic raises renewed concerns about inequality. Leveraging pre–post data from a population-representative sample of Indiana residents, we examine employment and food, housing, and financial...

Importance In response to the increase in opioid overdose deaths in the United States, many states recently have implemented supply-controlling and harm-reduction policy measures. To date, an updated policy evaluation that considers the full policy landscape has not been conducted. Objective To evaluate 6 US state-level drug policies to ascertain...

Students with disabilities are disciplined at disproportionately high rates, despite federal laws designed to ensure disciplinary protection. We examine the association between disability and discipline using a novel approach, investigating whether behavior problems trigger special education referral, and if disciplinary outcomes change once studen...

Although it is widely accepted that personal networks influence health and illness, network recall remains a major concern. This concern is heightened when studying a population that is vulnerable to cognitive decline. Given these issues, we use data from the Social Network in Alzheimer Disease project to explore similarities and discrepancies betw...

Introduction: Willingness to participate in COVID-19 testing and tracing programs has potential to exacerbate health disparities due to systematic variation by social determinants of health. This study evaluates sociodemographic, economic, and psychological factors associated with COVID-19 testing motivations.Methods: We used data from the Person t...

Objectives: We examined whether social isolation due to the COVID-19 shelter-in-place orders was associated with greater loneliness and depression for older adults, and, if so, whether declines in social engagement or relationship strength moderated that relationship. Method: Between April 21-May 21, 2020, 93 older adults in the United States wh...

Social network analysts typically study node prominence in bipartite social networks with methods that do not fully account the two-mode topology of the underlying social network. Recent studies have generated a number of algorithms that might estimate node prominence in bipartite graphs with greater accuracy; however, it is unclear how these algor...

Despite decades of research and dozens of public health campaigns, stigma continues to negatively affect the well-being and life chances of people labeled with a mental illness. One of the most promising directions for reducing stigma lies in Allport’s (1954) theory of intergroup contact, suggesting that social interactions with people with mental...

Background and Aims Our ability to combat the opioid epidemic depends, in part, on dismantling the stigma that surrounds drug use. However, this epidemic has been unique and, to date, we have not understood the nature of public prejudices associated with it. Here, we examine the nature and magnitude of public stigma toward prescription opioid use d...

This paper examines network prominence in a co-prescription network as an indicator of opioid doctor shopping (i.e., fraudulent solicitation of opioids from multiple prescribers). Using longitudinal data from a large commercially insured population, we construct a network where a tie between patients is weighted by the number of shared opioid presc...

Objective To examine outcomes in a 4-year college pilot program built on stigma change research. U Bring Change to Mind (UBC2M) was developed and launched at Indiana University (IU) in 2014 as an institutionally supported, student-led organization to make campuses “safe and stigma-free zones.” The accompanying College Toolbox Project (CTP) assessed...

This study examined the effectiveness of participating in special education on the academic outcomes of students with disabilities. A sample of 575 students from a large, urban school district were followed longitudinally as they transitioned between general and special education to evaluate whether receiving special education services was associat...

Objective: To assess which mental health-related states of being are perceived as diseases by psychiatrists, non-psychiatric physicians, nurses, parliament members and laypeople. Design and setting: A population-based, mailed survey in Finland. Participants: Respondents from a random sample of 3000 laypeople, 1500 physicians, 1500 nurses and a...

Social influence is a key determinant of health behaviors and outcomes. Research in the social network tradition emphasizes social structural mechanisms like network content (i.e., the degree to which particular attitudes, attributes, or behaviors are present in the network) and social proximity (i.e., opportunities for social interaction). In cont...

This paper examines network prominence in a co-prescription network as an indicator of doctor shopping (i.e., fraudulent solicitation of prescriptions from multiple healthcare providers) for opioids. Using longitudinal data from a large commercially insured population, we construct a network where a tie between patients was weighted by the number o...

Latinos in the United States have poor outcomes for periodontal and dental health. However, a detailed description of the mechanisms driving these patterns has only recently started to be addressed in the literature. In the current study, we explore relationships between individual-level characteristics of Mexican immigrants, properties of their ne...

Compared to U.S. born Latinos, Mexican immigrants (MAs) have diminished health care access and face substantial barriers to accessing needed dental health services. However, little research has examined how MAs social networks shape their use of dental health services. Using data from 332 Mexican immigrants to the Midwest, this research examines th...

However, a detailed description of the mechanisms driving these patterns has only recently started to be addressed in the literature. In the current study, we explore relationships between individual-level characteristics of Mexican immigrants, properties of their ne...

With increasing rates of obesity in the United States, attention to life chances and psychological consequences associated with weight stigma and weight-based discrimination has also intensified. While research has demonstrated the negative effects of weight-based discrimination on mental health, little is known about whether different social group...

Mental health services and psychiatric professional values have shifted in the past several decades toward a model of client autonomy and informed consent, at least in principle. However, it is unclear how much has changed in practice, particularly in cases where client behavior poses ethical challenges for clinicians. Drawing on the case of client...

Purpose: Only a handful of studies have examined social interactions between parents and children around food choice, though these have important implications for health. Moreover, we know very little about how socioeconomic status might influence these exchanges, including the nature and outcomes of children's requests for specific foods and drink...

The current study compared perceived stress among married and single individuals across a variety of life domains in order to understand (1) the relationship between marital status and psychosocial mechanisms of stress and (2) the degree to which stress experienced in different domains is associated with other health problems (i.e., anxiety). Using...

Despite the growing potential for multiplexity in our complex social world, social network methodology often does not adequately capture this phenomenon. Most commonly in research on egocentric social networks, when a respondent designates a tie as both a family member and a friend, the tendency is to default to “family” prior to aggregation for an...

School disciplinary processes are an important mechanism of inequality in education. Most prior research in this area focuses on the significantly higher rates of punishment among African American boys, but in this article, we turn our attention to the discipline of African American girls. Using advanced multilevel models and a longitudinal data se...

Research in the area of social networks and health has demonstrated that lay social network members play a critical role in the early stages of the illness career, influencing key decisions and pathways to formal care. Here, we revisit and extend this body of work, examining how the lay social network context can moderate the influence of treatment...

Previous research has documented social contagion in obesity and related health behaviors, but less is known about the social processes underlying these patterns. Focusing on married or cohabitating couples, we simultaneously explore three potential social mechanisms influencing obesity: normative body size, social control, and behavior modeling. W...

Objective: To examine the influence of collectivist orientation (often called familismo when applied to the Latino sub-group in the United States) in oral health discussion networks. Basic research design: Through respondent-driven sampling and face-to-face interviews, we identified respondents' (egos) personal social network members (alters). E...

This study uses data from 564 African American women to examine the correlates of lifetime prevalence of a sexually transmitted infection (STI). Specifically, we test the effects of perceptions about the availability of African American males, five partner characteristics, and drug history. At the bivariate level, women with an STI diagnosis were s...

Objectives: We used data from the TalaSurvey study to examine associations between dental health experiences, social network characteristics, and levels of behavioral and psychological acculturation in one location in the American Midwest. Methods: Starting in parishes and community organizations, we identified adults of Mexican origin living in...

Background: The transmission of sexual images and messages via mobile phone or other electronic media (sexting) has been associated with a variety of mostly negative social and behavioural consequences. Research on sexting has focussed on youth, with limited data across demographics and with little known about the sharing of private sexual images a...

Misalignment of educational and career goals (i.e., educational aspirations expressed are inadequate for attaining one’s desired occupation) is associated with lower educational attainment and a lack of college readiness, and may contribute to persistent educational and employment disparities. Drawing on data from 249 sixth graders in low-income sc...

Purpose – While much research examines the consequences of deinstitutionalization for caregivers, few studies address support mobilization strategies used by patients themselves. We examine the relationship between mental health patients’ needs, their activation of network ties for health discussion, and network dynamics during the course of treatm...

Evidence that social and biological processes are intertwined in producing health and human behavior is rapidly accumulating. Using a feminist approach, this research explores how gender moderates the interaction between biological processes and men’s and women’s behavioral and emotional responses to similar social environments. Using data from the...

The therapeutic alliance is a critical determinant of individuals’ persistence and outcomes in mental health treatment. Simultaneously, individuals’ community networks shape decisions about whether, when, and what kind of treatment are used. Despite the similar focus on social relationship influence for individuals with serious mental illness, each...

This paper adds to research on girls’ growing educational advantage by examining gender differences in career paths. Using baseline data from an intervention study (TRY-IT!) targeting 265 sixth-graders in Title I schools, our research traces adolescent career aspirations by gender, race and class. Additionally, we investigate whether girls and boys...

While scholars have studied the racial “achievement gap” for several decades, the mechanisms that produce this gap remain unclear. In this article, we propose that school discipline is a crucial, but under-examined, factor in achievement differences by race. Using a large hierarchical and longitudinal data set comprised of student and school record...
