More adverse childhood experiences are associated with increased social thinning and severe psychological distress

Adverse childhood experiences have been linked to psychopathology due to reduced social networks or social thinning. However, evidence of the temporal associations between adverse childhood experiences, social networks, and psychopathology was lacking, as few studies assessed social networks repeatedly. Further, their underlying neurocognitive and biological mechanisms related to hypervigilance and inflammation remain unclear. This study aimed to clarify these associations using a three-wave population-based cohort study during the COVID-19 pandemic (n = 465), where we leveraged repeated social network assessments. Self-reported questionnaires assessed adverse childhood experiences, social network size and diversity, psychological distress, and hypervigilance regarding COVID-19. Blood tests were conducted to measure inflammation markers. Individuals with more adverse childhood experiences demonstrated lesser increases in their social networks than those without adverse childhood experiences. Decreased network sizes were associated with severe psychological distress, but this association did not remain after adjusting for baseline distress. On the other hand, reduced network diversities were associated with increased psychological distress. We did not find any paths through hypervigilance regarding COVID-19 and inflammation that explain associations between adverse childhood experiences, social thinning, and psychological distress. These findings emphasize the significant social network changes in the associations between adverse childhood experiences and psychopathology.

Correlates and Brain Substrates of Happiness in Community-Dwelling Older Adults in India.

Happiness has been shown to influence many health-related outcomes in older adults. Identifying correlates and brain substrates of happiness across countries and cultures is an important goal, as the global older adult population continues to increase. We used univariate and multiple regression to examine associations between happiness and several demographic, health, and lifestyle variables in 665 older adults (39% female) from Kerala, India. We also used Bayesian regression to examine associations between cortical thickness and happiness in a sub-sample of 188 participants that completed MRI scanning. Happiness was significantly associated with several variables. In our multiple regression model, which included all significant univariate predictors, self-rated health, depression, anxiety, apathy, social network size, social network diversity, and social support significantly predicted happiness. Demographic indicators (age, sex, education, marital status, residence, and employment status/type), cognitive impairment, comorbidities, and leisure activities were not significantly associated with happiness in the multiple regression model. Cortical thickness in several brain regions was positively associated with happiness scores, including frontal, temporal, parietal, occipital, and cingulate regions. Understanding the key correlates is critical for identifying both modifiable factors that can be targeted in well-being interventions and fixed characteristics that identify those at-risk for reduced happiness. The widespread pattern of brain regions associated with happiness is consistent with the multifactorial nature of happiness and, given that the regions identified do not overlap with those vulnerable to cortical thinning, can help explain why subjective well-being, unlike other cognitive functions, is largely resistant to age-related decline.

The role of social network diversity in self-perceptions of aging in later life

While the link between self-perceptions of aging (SPA) and healthy aging is well established, less is known about the association between social factors and SPA. The present study investigated whether higher social network diversity is associated with more positive and less negative SPA and whether this association is moderated by age. We examined cross-sectional data from the German Ageing Survey of 2008 (DEAS; N = 6205, 40–85 years, 49.5% female). Network diversity was assessed as the number of social roles in an individual’s network (such as spouse, friend and colleague). Three domains of SPA were measured using the Aging-Related Cognitions Scale (AgeCog): ongoing development (positive SPA), social losses (negative SPA) and physical losses (negative SPA). We conducted multiple linear regression models and tested for a moderator effect of age using an interaction term of age and network diversity. Results showed that at higher ages older adults with higher network diversity reported more positive SPA related to ongoing development and more negative SPA related to social losses than those with less diverse networks, indicating that age has a moderating effect. We found no association between network diversity and negative SPA related to physical losses and no indication that age was relevant to this relationship. The present study adds to evidence on the role of social networks in SPA. Our findings suggest that in certain SPA domains and depending on age, network diversity is related to both more positive and more negative SPA, which emphasizes the importance of considering domain-specific SPA.

Unveiling the Social Life of SuperAgers: A Narrative Review of Social Profiles of Exceptional Cognitive Aging

SuperAging deserves special attention from researchers in the field of the psychology of aging, because it denotes the preservation of multiple cognitive abilities in very old age. Currently, very little is known about lifestyle factors that could be related to SuperAging. The main goal of the present narrative review was to bring together available evidence involving social factors related to SuperAging and to target avenues for future research. The review summarizes the findings of studies published between 2005 and 2022. Low social participation in midlife age and high social participation in older age were found to be related to SuperAging. In contrast, social network size and diversity did not differ between SuperAgers and cognitively normal older adults. The synthesis of the results indicates that having positive, close, high-quality relationships and a high frequency of social contact may be considered to be hypothetical predictors of superior cognitive performance in later life.

Social network characteristics impact the recognition of degraded speech by adult cochlear implant users

Social networks influence the quantity and quality of linguistic input experienced in everyday listening environments. In normal-hearing listeners, the variable linguistic input provided by larger and more diverse social networks has been shown to support speech processing. However, for adult cochlear implant (CI) users, limitations in the perception of linguistic and talker details may limit input variability benefits. The current study examined the effects of social network size and diversity on the recognition of spectrotemporally degraded speech by adult CI users. Twenty-six postlingually deafened adult CI users completed a detailed questionnaire about their regular communication partners. Social network size was calculated as the number of regular communication partners, and social network diversity was calculated as the degree of age, education, and accent heterogeneity among communication partners. Social network metrics were compared to vowel, word, and sentence recognition accuracy scores, also controlling for basic auditory ability. Results showed that social network age diversity was moderately to strongly correlated with word and sentence recognition accuracy. Social network size and other diversity metrics were not related to word or sentence recognition accuracy. These findings suggest that more diverse input from different age groups facilitates spoken word recognition in adult CI users.

The role of social connection in opioid use disorder treatment engagement.

Medications for opioid use disorder (OUD or MOUD) treatment combining pharmacotherapy with psychosocial support are effective for managing OUD. However, treatment engagement remains a challenge, with retention rates ∼30%-50%. Although social connection has been identified as important to recovery, it remains unclear whether and how social factors can bolster participation in treatment. Individuals receiving MOUD at three outpatient treatment programs (N = 82) and healthy community controls (N = 62) completed validated measures assessing social connection including (a) size, diversity, and embeddedness of social networks; (b) perceived social support and criticism within familial relationships; and (c) subjective social status. For those receiving MOUD, we also examined how aspects of social connection related to opioid (re)use and treatment engagement (medication adherence, group, and individual meeting attendance) assessed over ∼8 weeks/person. Compared to controls, individuals receiving MOUD had smaller and less diverse and embedded social networks (Cohen's d > 0.4), and despite similar levels of perceived social support (d = 0.02), reported higher levels of social criticism (d = 0.6) and lower subjective social status (d = 0.5). Within the MOUD group, higher social network indices correlated specifically with higher therapeutic group attendance (Rs > 0.30), but not medication adherence, while higher levels of perceived criticism correlated with more frequent opioid use (R = 0.23). Results were mostly robust to control for sociodemographic variables, psychological distress/COVID-19, and treatment duration, but differed by MOUD type/program. These findings highlight the potential importance of assessing an individual's social capital, promoting positive social connection, and continuing to assess the implementation and value of psychosocial support in MOUD treatment.

Frequency of Going Outdoors and Risk of Poor Oral Health Among Older Japanese Adults: A Longitudinal Cohort From the Japan Gerontological Evaluation Study.

The association between the frequency of going outdoors and the risk of poor oral health has been reported in several studies; however, the findings have been inconclusive. We conducted a 3-year longitudinal study of 19,972 Japanese adults aged ≥65 years who reported no poor oral condition at baseline in 2013. The respondents rated their frequency of going outdoors in three categories (≤1, 2-3, or ≥4 times/week), and the oral conditions reported in 2016 included tooth loss, chewing difficulty, swallowing difficulty, dry mouth, and composite outcomes. The associations between the frequency of going outdoors and the risk of poor oral health were examined as relative risk ratios (RRs) and 95% confidence intervals (CIs) using multivariable Poisson regression, while mediation analysis was performed to investigate indirect effects. During the follow-up, 32.5% of participants developed poor oral health. In the mediation analysis, indirect effects were observed through low instrumental activities of daily living, depressive symptoms, little social network diversity, and underweight. Compared to going outdoors ≥4 times/week, the multivariable RRs of composite poor oral health conditions were 1.12 (95% CI, 1.05-1.20) for 2-3 times/week and 1.22 (95% CI, 1.07-1.39) for ≤1 time/week (P-trend < 0.001). Similar associations were observed for tooth loss, chewing difficulty, and swallowing difficulty; the corresponding RRs were 1.07 (95% CI, 0.97-1.19) and 1.36 (95% CI, 1.13-1.64) (P-trend = 0.002), 1.18 (95% CI, 1.06-1.32) and 1.30 (95% CI, 1.05-1.60) (P-trend < 0.001), and 1.15 (95% CI, 1.01-1.31) and 1.38 (95% CI, 1.08-1.77) (P-trend = 0.002), respectively. The frequency of going outdoors was inversely associated with the risk of poor oral health through several modifiable risk factors in the older population.

Incidence, Quality of Care, and Mortality in Hip Fracture Patients in the Course of the COVID Pandemic: A Population-Based Cohort Study.

We assessed the incidence, quality of in-hospital care, and mortality for hip fracture (HF) patients in Denmark before and during the coronavirus disease (COVID) pandemic. We obtained data from the Danish registries in the COVID period (March 11, 2020 to January 27, 2021, overall and in 5 periods) and compared it to a pre-COVID period (March 13, 2019 to March 10, 2020). We calculated the proportion of patients (%) that have fulfilled all the relevant quality indicators (a composite score of 100%) and adjusted hazard ratios (HR) with a 95% confidence interval (CI) for 30-day mortality. The incidence of HF was 5.7 per 1000 person-years both in pre-COVID and COVID periods. About 35% of patients had a composite score of 100% in the COVID period compared to 28% in the pre-COVID period (proportion ratio 1.23 [95% CI: 1.17-1.30]). Fulfillment of all individual quality indicators was similar or higher in the COVID period. 30-day mortality was 9.5% in pre-COVID period, compared to 10.8% in the COVID period (HR 1.15 [95% CI: 1.02-1.30]). HRs varied from 1.07 (95% CI: 0.89-1.29) to 1.31 (95% CI: 1.06-1.62) in 5 COVID periods. In-hospital mortality was 4% in pre-COVID versus 4.4% in COVID period. The incidence of HF in Denmark remained unchanged. The quality of in-hospital care was higher in the COVID compared to pre-COVID period. Unfortunately, 30-day mortality was also higher, highlighting the importance of recognizing diversity of social networks, home support, and digital health intervention after discharge for outcome of HF patients.

The Power of Diversity: Class, Networks and Attitudes Towards Inequality

We examine how inter-class relationships shape attitudes towards inequality. Our theoretical frame defines attitudes towards inequality as ethical dispositions and hypothesises that class-based network diversity may favour the development of what has been termed a ‘reflexive habitus’ that likely pushes for more egalitarian dispositions. The focus of our enquiry is on Chile – one of the most unequal countries in the world. We use large-scale representative survey data collected in 2016 (N = 2927). Results of our regression analyses indicate that class diversity in social networks strongly increases awareness of inequality and more egalitarian preferences while reducing belief in meritocracy and the perception that the current distribution is fair. Additional analyses suggest that network diversity influences views on inequality to a similar degree among individuals from different social classes, except for meritocratic beliefs, where network diversity especially affects the upper class. We conclude by discussing the importance of reducing socio-economic segregation.

29 Associations Between Social Support and Cognitive Performance Among Persons with MS

Objective:Social support is an emerging protective factor against cognitive decline. However, the relationship between social support and cognitive functioning in the multiple sclerosis (MS) population is not well understood. The present study aimed to investigate the associations between different aspects of social support and cognitive performance among persons with MS.Participants and Methods:A volunteer sample of 63 persons with MS (% female = 88.9, mean age = 48.16) completed measures assessing perceived levels of social support measured by the Medical Outcomes Study Support Social Survey 5-item short form (MSSS-5), and social network (social network diversity and total size of social network) measured by the Social Network Index (SNI). Cognitive functioning was assessed by a brief virtual examiner-administered neuropsychological test battery (using a teleconferencing platform), including the Rey Auditory Verbal Learning Test, Controlled Oral Word Association Test, animal naming, and the Symbol Digit Modalities Test. Participants also completed brief, self-paced, virtual cognitive tests through the testmybrain.org platform, which consisted of digit span and the Trail-Making Test. A principal component analysis (PCA) was carried out to reduce the number of neuropsychological outcomes into fewer dimensions. Multiple linear regressions were conducted to examine the associations between social support measures and cognitive performance. Regression models were adjusted by the levels of depressive symptoms (operationalized by the Chicago Multiscale Depression Inventory or the Hospital Anxiety and Depression Scale) and premorbid functioning (measured by the Test of Premorbid Functioning).Results:A PCA reduced neuropsychological outcomes into 3 components representing cognitive domains of 1) processing speed/executive functioning, 2) verbal memory, and 3) verbal fluency / simple attention. In the unadjusted models, both perceived social support (i.e., to what extent one receives assistance from their social network) as well as total size of social network (i.e., total number of people one regularly talks to) were significant predictors of the processing speed/executive functioning component score of moderate strength, where F(1, 59) = 11.93, p = .001, β = 0.41 and F(1, 59) = 11.57, p = .001, β = 0.41, respectively. These associations were maintained after adjusting for depressive symptoms and level of premorbid functioning (F(4, 55) = 3.31, p = .003 and F(4, 55) = 3.31, p = .006, respectively). On the other hand, social network diversity (i.e., number of different types of close social relationships one has) was not a significant predictor of the processing speed/executive functioning component score (p &gt; 0.05). None of the social support measures were significantly associated with the verbal memory and verbal fluency/simple attention component scores.Conclusions:Greater social support (specifically, perceived levels of assistance and total size of social network) is associated with better performance on processing speed/executive functioning measures among persons with MS, independent of effects from depressive symptoms and premorbid functioning. Maintaining a strong social support network may be an important factor in optimizing cognitive health in MS.

Does racial diversity affect White children's racial bias and reasoning? Depends on where they live and how their social world is structured.

By 4 years of age, White children from across the United States begin to exhibit an awareness of racial inequalities, along with in-group preferences for other White children. The present study explored how the size and racial diversity of White children's social network (e.g., friends, family, and classmates) and neighborhood (zip code) are related to variation in their explanations for racial disparities and anti-Black bias among a sample of 395 White children (ages = 4-11 years old; Mage = 6.6 years) from 263 unique zip codes across the United States. White children in neighborhoods with low diversity were more likely to endorse an extrinsic explanation for racial inequality as their network diversity increased, whereas network diversity did not relate to children's choices for those who lived in neighborhoods with high diversity. These findings held even after controlling for parents' beliefs about diversity, which were themselves positively correlated with children's network and neighborhood diversity. An exploratory analysis revealed that for White children in small networks only, as the number of children of color in their network increased, they were more likely to choose to play with a Black child. Results demonstrate how the diversity of children's social networks and neighborhoods relates to children's developing racial beliefs in contextually dependent ways.

Cognitive empathy mediates the relationship between gray matter volume size of dorsomedial prefrontal cortex and social network size: A voxel-based morphometry study

Social networks are an important factor in developing and maintaining social relationships. The social brain network comprises brain regions that differ in terms of their location, structure, and functioning, and these differences tend to vary among individuals with different social network sizes. However, it remains unknown how social cognitive abilities such as empathy can affect social network size. The goal of our study was to examine the relationship between brain regions in the social brain network, empathy, and individual social network size by using the Social Network Index, which measures social network diversity, size, and complexity by assessing 12 different types of relationships. We performed voxel-based morphometry and mediation analyses using data from questionnaires and structural magnetic resonance imaging data in a sample of 204 young adults. Our findings showed that the gray matter volume of the dorsomedial prefrontal cortex (dmPFC) was inversely associated with social network size and cognitive empathy mediated this association, suggesting that decreased gray matter volume in the dmPFC is associated with greater utilization of cognitive empathy, which, in turn, seems to increase social network size. A potential mechanism explaining this inverse relationship could be cognitive pruning, a phenomenon that occurs in the brain between early adolescence and adulthood, but future longitudinal studies are needed. In conclusion, our findings provide information about the neurocognitive mechanisms involved in the formation and maintenance of social networks.

Infants' visual attention to own-race and other-race faces is moderated by experience with people of different races in their daily lives.

Infants sometimes differentially attend to faces of different races, but how this tendency develops across infancy and how it may vary for infants growing up with different exposure to racial diversity remain unclear. The present study examined the role of experiences with racial diversity on infants' visual attention to different racial groups (specifically own-race vs. other-race groups) in the first year of life via a large-scale study of infants (N = 203; Mage = 6.9 months, range = 3-14 months; 70% White, 8% Asian, 5% Black, 12% multiracial, 4% unreported; 14% Hispanic, 86% non-Hispanic) from across the United States. We tested the role of two forms of racial diversity: that of infants' social networks (reported by parents) and that of infants' neighborhoods (obtained from U.S. Census data). Regardless of age, infants looked longer at other-race faces than own-race faces, but this tendency was moderated by the racial diversity of infants' social networks. Infants with more diverse networks looked equivalently long at own-race and other-race faces, whereas those with less diverse networks looked longer at other-race faces. In contrast, infants' looking behavior was not moderated by the diversity of their neighborhoods. Together, our research suggests that exposure to racial diversity in infants' immediate social networks predicts how infants look to faces of different races, illustrating the context-dependent nature of the development of infants' attention to race.

Examining the social networks of older adults receiving informal or formal care: a systematic review

PurposeTo address the care needs of older adults, it is important to identify and understand the forms of care support older adults received. This systematic review aims to examine the social networks of older adults receiving informal or formal care and the factors that influenced their networks.MethodsA systematic review was conducted by searching six databases from inception to January 31, 2023. The review included primary studies focusing on older adults receiving long-term care, encompassing both informal and formal care. To assess the risk of bias in the included studies, validated appraisal tools specifically designed for different study types were utilized. Network analysis was employed to identify the grouping of study concepts, which subsequently formed the foundation for describing themes through narrative synthesis.ResultsWe identified 121 studies relating to the formal and informal care of older adults’ networks. A variety of social ties were examined by included studies. The most commonly examined sources of care support were family members (such as children and spouses) and friends. Several factors were consistently reported to influence the provision of informal care, including the intensity of networks, reciprocity, and geographical proximity. In terms of formal care utilization, older age and poor health status were found to be associated with increased use of healthcare services. Additionally, physical limitations and cognitive impairment were identified as factors contributing to decreased social engagement.ConclusionThis review found that older people were embedded within a diverse network. The findings of this review emphasize the importance of recognizing and incorporating the diversity of social networks in care plans and policies to enhance the effectiveness of interventions and improve the overall well-being of older adults.

Examining the Cross-Level Dynamics of Gender and Diversity in Social Networks

Examining the Cross-Level Dynamics of Gender and Diversity in Social Networks

Composition of social networks to build recovery capital differ across early and stable stages of recovery

Background Recovery capital describes the sum of resources – personal, social, or community – that can be drawn upon to sustain recovery from addiction. Recovery capital increases with progression through the stages of recovery; early (< 1 year), sustained (1 to 5 years), stable (> 5 years). The proportion of people in recovery within one’s social network, as well as the number of supports, have been associated with greater recovery capital, although recovery capital has been found to be lower if one’s entire network is in recovery. It remains unclear which social network characteristics are more important at early compared to stable recovery stages. Method The study assesses recovery strengths and barriers using the Strengths and Barriers Recovery Scale (SABRS) from the Australian Life in Recovery survey (n = 478). SABRS scores were compared between periods of active addiction and recovery, and across the stages of recovery. The impact of social network characteristics on SABRS score across early and stable recovery stages were also explored. Results Recovery social network diversity (some network members in recovery but not all or none) was associated with more recovery strengths in early but not stable recovery. However, for those in stable recovery, having a greater number of close people in a network was more important. Conclusion The study provides evidence that the elements (e.g. diversity and number of supports) of a social network that facilitate recovery capital change as individuals progress through recovery stages, and highlights the importance of peer support in early recovery.

Gambling lifestyles: The importance of social capital and diverse networks

ABSTRACT Scholars often overlook leisure gambling perspectives and focus on more health-related mechanisms, such as compulsive gambling behaviours. Consequently, understanding gambling as leisure is under-explored, especially in an economic sociological context. We begin to address this gap by identifying whether (1) leisure gambling is stratified across gambling activities and society, (2) social capital and (3) diverse networks are essential in leisure gambling consumption. Using 12,991 respondents to the 2007–2008 Taking Part Survey, we apply latent class analysis to identify different typologies of leisure gamblers, modelling the influence of socio-cultural characteristics and network resources and diversity. We identify five leisure gambling typologies, with social capital and network diversity playing an important role in their formation. Generally, leisure gambling consumption depends on more social capital and diverse networks.

Cross-sectional study of the association of social relationship resources with Staphylococcus aureus colonization in naturally occurring social groups along the US/Mexico border.

Asymptomatic carriage of Staphylococcus aureus is a major risk factor for subsequent clinical infection. Diminishing returns from mitigation efforts emphasize the need to better understand colonization, spread, and transmission of this opportunistic pathogen. While contact with other people presents opportunities for pathogen exposure and transmission, diversity of social connections may be protective against pathogens such as the common cold. This study examined whether social relationship resources, including the amount and diversity of social contacts, are associated with S. aureus colonization. Participants were community members (N = 443; 68% Hispanic) in naturally occurring social groups in southwestern Arizona. Four types of social relationships and loneliness were assessed, and samples from the skin, nose and throat were obtained to ascertain S. aureus colonization. Overall S. aureus prevalence was 64.8%. Neither the amount nor the diversity of social contacts were associated with S. aureus colonization. The concurrent validity of the social relationship assessments was supported by their moderate intercorrelations and by their positive association with self-rated health. The results suggest that the association of social network diversity and susceptibility to the common cold does not extend to S. aureus colonization. Conversely, colonization prevalence was not higher among those with more social contacts. The latter pattern suggests that social transmission may be relatively infrequent or that more intimate forms of social interaction may drive transmission and colonization resulting in high community prevalence of S. aureus colonization. These data inform communicable disease control efforts.

Social Network Diversity and the Daily Burden of Inflammatory Bowel Disease.

To examine the association between social network, daily inflammatory bowel disease (IBD) burden, and related cognitive factors such as loneliness and psychological well-being. Using survey data, we compared the relationship between social network diversity and daily IBD burden with multivariable linear regression. Patients with IBD with higher social network diversity reported a lower daily IBD burden. This association was more common among those who reported a higher degree of loneliness than those with a low degree of loneliness. We should consider diverse social connections as an indicator of risk for higher IBD burden, especially among lonely patients.

Social Network Diversity and Mental Health Among Mothers of Individuals With Autism.

The present study examined the associations between networks of social relationships and psychological well-being among mothers of adolescents and adults with autism (n = 352) over a 12-year period of time. A structural equation modeling approach was used to delineate the relative impacts of network size and relationship diversity on maternal mental health, and to assess whether such effects are bidirectional. Mothers with more diverse relationships experienced reductions in depression and anxiety symptoms over time, and the psychological benefits of diversity remained after adjusting for network size. Results also suggest bidirectional links between network size, diversity, and maternal mental health. Research and clinical implications are discussed.
