Social Media Use and Perceived Social Isolation Among Young Adults in the U.S

Problematic Social Media Use and Perceived Social Isolation in Older Adults: A Cross-Sectional Study

BACKGROUND

Social isolation in older adults is associated with numerous adverse health outcomes. In today's digital society, if individuals perceive themselves to be socially isolated, they can take steps to interact with others on social media platforms. Research with younger adults indicates that social media use is positively linked to social isolation. However, less is known about social media use and social isolation in older adults.

OBJECTIVE

The objective of this study was to investigate the possible association between social isolation and degree of social media use in older adults.

METHODS

Using Internet sources, we recruited 213 participants (79.8% female; mean age 62.6 years, SD 8.3) who responded to an online survey focusing on living situation, depression, social isolation, and 2 measures of social media use: estimated daily time on social media and problematic social media use. Next, using binary logistic regression, we assessed associations between social isolation and social media use.

RESULTS

Our analyses failed to identify a relationship between perceived social isolation and estimated daily time on social media; however, higher problematic social media use was associated with higher perceived social isolation (OR 1.17).

DISCUSSION AND CONCLUSION

Although no causal attribution can be made, our findings demonstrate an association between problematic social media use and perceived social isolation in older adults. Researchers conducting social media interventions in older adults should note this potential and monitor maladaptive use of these platforms. Overall, our results provide an important starting point for future studies on social media use and social isolation in older adults.

Fashion Promotion on Instagram with Eye Tracking: Curvy Girl Influencers Versus Fashion Brands in Spain and Portugal

The rise of Instagram, as the fastest growing social network in Spain and Portugal, and its incorporation into the communication strategies of beauty and fashion brands have posed some risks for younger followers in relation to the development of identity and self-esteem. A physical appearance acceptance movement has also begun, based on interaction with images, on which the social network is also based. The purpose of this research was to determine how attention is paid to fashion promotion and to the awareness of physical appearance acceptance by curvy influencers in comparison with communications by fashion brands on Instagram. The quantitative and qualitative methodology is based on the use of a biometric eye tracking technique applied to a sample of 120 participants from Spain and Portugal, matching the profile of the main users of Instagram: urban university women under 25 years old with an interest in fashion, and a self-perception as a curvy woman. The results point to more attention focused on the imperfections for which curvy influencers are raising awareness than on the fashion they promote when these awareness factors are more visible, as well as more attention focused on the fashion accessories worn by curvy brand models than those worn by the influencers, with specific and significant differences between Spanish and Portuguese audiences.

Why increases in adolescent depression may be linked to the technological environment

Between 2011 and 2018, rates of depression, self-harm, and suicide attempts increased substantially among U.S. adolescents. The most probable cause(s) of these trends likely 1) began or accelerated during these years, 2) affected a large number of people, 3) impacted everyday life, and 4) were associated with depression. In several large studies, heavy users of technology are twice as likely as light users to be depressed or have low well-being. Cohort declines in face-to-face social interaction may also impact even non-users of digital media. Thus, although technology use is not the cause of most depression, increased time spent on technology and the technological environment may be causes of the sudden increase in depression since 2011.

Desire to Belong Affects Instagram Behavior and Perceived Social Support

Social networking site (SNS) use has been shown to predict both positive and negative well-being. These discrepant findings may be explained by people's motivations for and frequency of using SNSs. This study aimed to explore how frequency of online interactions can be affected by users' motives, specifically, being motivated by a sense of belonging, and possible perceived social support derived from the popular image-based SNS, Instagram. A total of 313 Instagram users (84.4% female, median age = 22 years) completed an online survey between March and September 2017 asking about their motives for using Instagram, perceived social support, and frequency of Instagram use. Multiple regression mediation analyses examined the relationship between being motivated by a desire to belong, mediator variables (frequency of posting, liking, and viewing posts), and perceived social support. A greater desire to belong significantly positively predicted frequency of Instagram use, total perceived social support, and perceived social support from friends and significant others. However, frequency of Instagram use did not predict perceived social support. As such, frequency of Instagram use did not mediate the relationship between motivation and social support. Future research could explore how other user motives and peer feedback affect Instagram use and other well-being outcomes.

Models and theories of health behavior and clinical interventions in aging: a contemporary, integrative approach

Background: Historically, influential models and theories of health behavior employed in aging research view human behavior as determined by conscious processes that involve intentional motives and beliefs. We examine the evolution, strengths, and weaknesses of this approach; then offer a contemporary definition of the mind, provide support for it, and discuss the implications it has for the design of behavioral interventions in research on aging. Methods: A narrative review was conducted. Results: Traditionally, models and theories used to either predict or change health behaviors in aging have not viewed the mind as encompassing embodied and relational processes nor have they given adequate attention to multi-level, in-the-moment determinants of health behavior. Discussion: Future theory and research in aging would benefit from a broader integrative model of health behavior. The effects of adverse life experience and changes in biological systems with aging and chronic disease on health behavior warrant increased attention.

More Time on Technology, Less Happiness? Associations Between Digital-Media Use and Psychological Well-Being

Studies using large samples consistently find that more frequent users of digital media are lower in psychological well-being than less frequent users; even data sets used as evidence for weak effects show that twice as many heavy users (vs. light users) are low in well-being. Differences in perspective may stem from the statistics used; I argue that comparing well-being across levels of digital-media use is more useful than the percentage of variance explained, as most studies on digital-media use do not measure other influences on well-being (e.g., genetics, trauma), and these other influences, unlike frequency of digital-media use, are rarely controllable. Nonusers are generally lower in well-being than light users of digital media, however, suggesting that limited use may be beneficial. Longitudinal and experimental studies suggest that at least some of the causation moves from digital-media use to lower well-being. Mechanisms may include the displacement of activities more beneficial to well-being (sleep, face-to-face social interaction), upward social comparison, and cyberbullying.

Estimating Determinants of Attrition in Eating Disorder Communities on Twitter: An Instrumental Variables Approach

BACKGROUND

The use of social media as a key health information source has increased steadily among people affected by eating disorders (EDs). Research has examined characteristics of individuals engaging in online communities, whereas little is known about discontinuation of engagement and the phenomenon of participants dropping out of these communities.

OBJECTIVE

This study aimed to investigate the characteristics of dropout behaviors among eating disordered individuals on Twitter and to estimate the causal effects of personal emotions and social networks on dropout behaviors.

METHODS

Using a snowball sampling method, we collected a set of individuals who self-identified with EDs in their Twitter profile descriptions, as well as their tweets and social networks, leading to 241,243,043 tweets from 208,063 users. Individuals' emotions are measured from their language use in tweets using an automatic sentiment analysis tool, and network centralities are measured from users' following networks. Dropout statuses of users are observed in a follow-up period 1.5 years later (from February 11, 2016 to August 17, 2017). Linear and survival regression instrumental variables models are used to estimate the effects of emotions and network centrality on dropout behaviors. The average levels of attributes among an individual's followees (ie, people who are followed by the individual) are used as instruments for the individual's attributes.

RESULTS

Eating disordered users have relatively short periods of activity on Twitter with one half of our sample dropping out at 6 months after account creation. Active users show more negative emotions and higher network centralities than dropped-out users. Active users tend to connect to other active users, whereas dropped-out users tend to cluster together. Estimation results suggest that users' emotions and network centralities have causal effects on their dropout behaviors on Twitter. More specifically, users with positive emotions are more likely to drop out and have shorter lasting periods of activity online than users with negative emotions, whereas central users in a social network have longer lasting participation than peripheral users. Findings on users' tweeting interests further show that users who attempt to recover from EDs are more likely to drop out than those who promote EDs as a lifestyle choice.

CONCLUSIONS

Presence in online communities is strongly determined by the individual's emotions and social networks, suggesting that studies analyzing and trying to draw condition and population characteristics through online health communities are likely to be biased. Future research needs to examine in more detail the links between individual characteristics and participation patterns if better understanding of the entire population is to be achieved. At the same time, such attrition dynamics need to be acknowledged and controlled when designing online interventions so as to accurately capture their intended populations.

The development of intimate relationships in adolescent girls and women with traumatic brain injury: a framework to guide gender specific rehabilitation and enhance positive social outcomes

Background: Traumatic brain injury is a neurological disorder of biopsychosocial nature influenced by sex and gender interactions across the lifespan. Traumatic brain injury sustained during adolescence can result in cognitive and social communication impairments that compromise the development and maintenance of intimate social relationships. This can increase both short and long-term vulnerability to poor mental health, social isolation, lack of meaningful friendships, exploitation, and abuse. Females with traumatic brain injury experience greater loss of confidence and have increased risk of victimization, sexual abuse, and violence. This paper aims to provide a framework to inform gender specific rehabilitation of social communication and intimacy, to enhance positive social outcomes for girls and women with Traumatic Brain Injury.Methods: The framework is developed through presentation of a conceptual, multi-dimensional model of intimacy and discussion of current evidence regarding trauma-related cognitive/social-communication impairments and considerations regarding social media.Results: Intimacy is strongly influenced by today's technology-informed "youth culture" and for those with Traumatic Brain Injury, is impacted by cognitive and social communication impairments. Females experience different challenges in recovery and experience of intimacy. There is a need to support girls and women with Traumatic Brain Injury as they develop intimate relationships.Conclusions: This framework can guide the development of female gender-specific rehabilitation and inform future research to promote positive social outcomes.Implications for rehabilitationIntimate relationships are a critical component of mental health and an important part of human development; however, the challenges faced by adolescent girls and woman with TBI in developing and maintaining intimate relationships are often overlooked in traditional rehabilitation programs.A multi-dimensional model of intimacy will help rehabilitation professionals understand the complexities of interventions needed to support healthy intimacy, as well as for harm prevention.Rehabilitation professionals play an important role in advocating for gender-specific supports and interventions.There is a need for early interventions, grounded in today's technological and social media culture, that will support healthy intimacy for adolescent girls and women with TBI.

Long-Term Behavioral Effects of Post-weaning Social Isolation in Males and Females

Adolescence is a developmental period associated with vast neural and behavioral changes which are accompanied by altered sensitivity to stimuli, both stressful and rewarding. Perturbations, especially stressful stimuli, during this period have been shown to alter behavior in adulthood. Social isolation rearing is one such perturbation. This review highlights the long-term behavioral consequences of adolescent social isolation rearing in rodents with a specific focus on anxiety- and addiction-related behaviors. Sex-specific effects are discussed where data are available. We then consider changes in monoaminergic neurotransmission as one possible mechanism for the behavioral effects described. This research on both normative and perturbed adolescent development is crucial to understanding and treating the increased vulnerability to psychiatric disorders seen in humans during this life stage.

Using Skype to Beat the Blues: Longitudinal Data from a National Representative Sample

OBJECTIVES

This study aimed to determine whether use of certain types of online communication technology is associated with subsequent depressive symptoms.

DESIGN

Nationally representative, population-based prospective cohort.

SETTING

Data were obtained from the 2012 and 2014 waves of the Health and Retirement Study (HRS).

PARTICIPANTS

1,424 community-residing older adults (mean age, 64.8) in the United States.

MEASUREMENTS

We examined associations between use of four communication technologies (email, social networks, video chat, and instant messaging) in 2012 and depressive symptoms (eight-item Center for Epidemiologic Studies Depression scale) at two-year follow-up.

RESULTS

564 participants (39.6%) did not use any communication technologies, 314 (22.1%) used email only, and 255 (17.9%) used video chat (e.g., Skype). Compared to non-users (13.1%, 95% CI: 9.5-16.7%) or those who used only email (14.3%, 95% CI: 10.1-18.5%), users of video chat had approximately half the probability of depressive symptoms (6.9%, 95% CI: 3.5-10.3%, Wald Chi² test, Chi²₍₁₎=13.82, p < 0.001; 7.6%, 95% CI: 3.6-11.6, Wald Chi² test, Chi²₍₁₎=13.56, p < 0.001). Use of email, social media, and instant messaging were not associated with a lower risk of depression.

CONCLUSIONS

Older adults who use video chat such as Skype, but not other common communication technologies, have a lower risk of developing depression.

Positive and Negative Experiences on Social Media and Perceived Social Isolation

PURPOSE

To examine the association between positive and negative experiences on social media (SM) and perceived social isolation (PSI).

DESIGN

Cross-sectional survey.

SETTING

One large mid-Atlantic University.

PARTICIPANTS

A total of 1178 students aged 18 to 30 were recruited in August 2016.

MEASURES

Participants completed an online survey assessing SM use and PSI. We assessed positive and negative experiences on SM by directly asking participants to estimate what percentage of their SM experiences involved positive and negative experiences, respectively. Social isolation was measured using the established Patient-Reported Outcomes Measures Information System scale.

ANALYSIS

We used multivariable logistic regression to assess associations between both positive and negative experiences on SM and PSI. Primary models controlled for sex, age, race/ethnicity, educational status, relationship status, and living situation.

RESULTS

Participants had an average age of 20.9 (standard deviation = 2.9) and were 62% female. Just over one-quarter (28%) were nonwhite. After controlling for all sociodemographic covariates, each 10% increase in positive experiences was not significantly associated with social isolation (adjusted odds ratio [AOR] = 0.97; 95% confidence interval [CI]: 0.93-1.005). However, each 10% increase in negative experiences was associated with a 13% increase in odds of PSI (AOR = 1.13; 95% CI: 1.05-1.21).

CONCLUSION

Having positive experiences on SM is not associated with lower social isolation, whereas having negative experiences on SM is associated with higher social isolation. These findings are consistent with the concept of negativity bias, which suggests that humans tend to give greater weight to negative entities compared with positive ones.

The association between use of online social networks sites and perceived social isolation among individuals in the second half of life: results based on a nationally representative sample in Germany

BACKGROUND

To date, little is known about the association between the use of online social network sites and social isolation among individuals in the second half of life. Therefore, the aim of the present study was to examine this association among older adults.

METHODS

Cross-sectional data was drawn from a nationally representative sample of non-institutionalized individuals aged 40 and above (n = 7837) in Germany (German Ageing Survey). Online social network use was assessed using the frequency of social network use (e.g., Facebook) in the preceding 12 months (daily; several times a week; once a week; 1-3 times a month; less often; never). Perceived social isolation was measured using an established scale created by Bude and Lantermann.

RESULTS

Adjusting for covariates, linear regressions revealed that daily online social network users reported lower social isolation scores compared with those with less frequent or no social media use.

CONCLUSIONS

Data suggest that daily users of online social networks aged 40 and over tend to feel less socially isolated than less frequent users or non-users. Future research should concentrate on identifying the direction of this association. Moreover, the reasons underlying this finding should be examined.

A Pilot Digital Intervention Targeting Loneliness in Youth Mental Health

Background: Loneliness is an emerging issue for young people, but yet many interventions to address loneliness in this group focus on providing social opportunities. While these sorts of interventions may appear to increase social connections, loneliness is more related to quality rather than quantity of social relationships. Thus, interventions addressing loneliness should focus on maximizing the quality of current relationships. Together with youth consumers both with mental ill health and those without, we developed a digital smartphone application (app) called +Connect. The 6-week program delivers positive psychology content designed to improve relationship quality. We tested the acceptability, feasibility, and safety of the program in lonely young people with or without a mental health diagnosis of social anxiety disorder. We used a mixed method study design to triangulate pilot quantitative and qualitative data in young people with and without social anxiety disorder (SAD). Method: Nine participants with a diagnosis of social anxiety disorder (M _age = 21.00; SD = 1.41) and 11 participants with no mental health conditions (M _age = 20.36; SD = 2.16) completed the +Connect digital intervention. Results: Those with social anxiety disorder reported less acceptable ratings on outcomes. Feasibility ratings, measured by uptake and app completion, met a priori threshold criteria in both groups. Those with social anxiety disorder yielded more attrition, with almost double the attrition rate compared with those without the disorder. There were no safety issues elicited during the pilot study. In terms of outcomes, exploratory analyses indicated that the app itself is likely to be beneficial rather than cause harm. Our qualitative data indicated both groups reported no negative outcomes and noted that positive outcomes were driven by three processes: reflection, learning, and real-life application. Further exploratory data on usability indicated room for improvement in terms of giving more support for different components of the app (i.e., challenges). Conclusion: The pilot findings of this proof-of-concept app indicates some promise in terms of a second iterative version of +Connect.

Examining Integrated Youth Services Using the Bioecological Model: Alignments and Opportunities

Integrated youth service (IYS) is a collaborative approach that brings practitioners together from across disciplines to provide comprehensive services including mental health care for youth and their families. IYS models serve as an advancement in practice as they go beyond the capacity of individual programs and services to reduce the fragmentation of care. Yet, there continue to be opportunities to expand on this perspective and promote health beyond the scope of formalized services. The bioecological model is a theoretical model that examines individual development within multiple systems of influence as well as through interactional processes between the individual and their environment. This paper provides an overview of the bioecological model and the major components of the IYS model, describing alignment and complementarity. The bioecological model provides some explanations for why IYS models may be effective and helps to provide direction to expand applied practice toward a more holistic perspective.

Identifying and Understanding Communities Using Twitter to Connect About Depression: Cross-Sectional Study

BACKGROUND

Depression is the leading cause of diseases globally and is often characterized by a lack of social connection. With the rise of social media, it is seen that Twitter users are seeking Web-based connections for depression.

OBJECTIVE

This study aimed to identify communities where Twitter users tweeted using the hashtag #MyDepressionLooksLike to connect about depression. Once identified, we wanted to understand which community characteristics correlated to Twitter users turning to a Web-based community to connect about depression.

METHODS

Tweets were collected using NCapture software from May 25 to June 1, 2016 during the Mental Health Month (n=104) in the northeastern United States and Washington DC. After mapping tweets, we used a Poisson multilevel regression model to predict tweets per community (county) offset by the population and adjusted for percent female, percent population aged 15-44 years, percent white, percent below poverty, and percent single-person households. We then compared predicted versus observed counts and calculated tweeting index values (TIVs) to represent undertweeting and overtweeting. Last, we examined trends in community characteristics by TIV using Pearson correlation.

RESULTS

We found significant associations between tweet counts and area-level proportions of females, single-person households, and population aged 15-44 years. TIVs were lower than expected (TIV 1) in eastern, seaboard areas of the study region. There were communities tweeting as expected in the western, inland areas (TIV 2). Counties tweeting more than expected were generally scattered throughout the study region with a small cluster at the base of Maine. When examining community characteristics and overtweeting and undertweeting by county, we observed a clear upward gradient in several types of nonprofits and TIV values. However, we also observed U-shaped relationships for many community factors, suggesting that the same characteristics were correlated with both overtweeting and undertweeting.

CONCLUSIONS

Our findings suggest that Web-based communities, rather than replacing physical connection, may complement or serve as proxies for offline social communities, as seen through the consistent correlations between higher levels of tweeting and abundant nonprofits. Future research could expand the spatiotemporal scope to confirm these findings.

Social Media Consequences of Pediatric Death

Social media is an important access point for engagement of children and adolescents. For individuals with a life-limiting illness or serving as the caregiver for an ill child, social media can be a helpful outlet for support and information gathering. It has democratized the process of being remembered through providing an ongoing account of thoughts, pictures, and videos that theoretically live on forever via a digital legacy. Providers should be familiar with how this new generation uses social media during their illness, after death, and in the bereavement process.

The Use of Online Pornography as Compensation for Loneliness and Lack of Social Ties Among Israeli Adolescents

The Internet provides people with the ability to act anonymously, which may lead them to feel secure and to release them from many of their inhibitions. In many cases, this leads them to participate in cybersex activities and online pornography. This study examined the psychological factors behind young people’s sexual behavior online. Participants comprised 713 Israeli adolescents (383 boys and 330 girls) aged 14 to 18 years. Our results indicated that the impact of loneliness on online sexual activity and frequency of pornography use was dependent on participants’ attachment orientations. Engagement in online sexual activities and use of pornography were high among anxiously attached individuals regardless of the extent of their loneliness. Loneliness was found to increase the use of online sexual activities and pornography, only among secure and anxiously avoidant individuals. Online sexual activity and pornography were also found to be related to offline sexual activity. The results are described and discussed.

Disentangling the role of users' preferences and impulsivity traits in problematic Facebook use

The use of social network sites (SNSs) has grown dramatically. Numerous studies have shown that SNS users may suffer from excessive use, associated with addictive-like symptoms. With a focus on the popular SNS Facebook (FB), our aims in the current study were twofold: First, to explore the heterogeneity of FB usage and determine which kind of FB activity predicts problematic usage; second, to test whether specific impulsivity facets predict problematic use of FB. To this end, a sample of FB users (N = 676) completed an online survey assessing usage preferences (e.g., types of activities performed), symptoms of problematic FB use and impulsivity traits. Results indicated that specific usage preferences (updating one’s status, gaming via FB, and using notifications) and impulsive traits (positive and negative urgency, lack of perseverance) are associated to problematic FB use. This study underscores that labels such as FB “addiction” are misleading and that focusing on the actual activities performed on SNSs is crucial when considering dysfunctional usage. Furthermore, this study clarified the role of impulsivity in problematic FB use by building on a theoretically driven model of impulsivity that assumes its multidimensional nature. The current findings have identifiable theoretical and public health implications.

Informal Caregivers' Experiences and Perceptions of a Web-Based Peer Support Network: Mixed-Methods Study

Background

Web-based peer support interventions have shown promise in reducing social isolation and social support deficits among informal caregivers, but little research has examined how caregivers use and perceive these interventions.

Objective

In this study, we examined utilization and perceptions of a Web-based social support intervention for informal caregivers of wounded, ill, and injured United States military service members and veterans.

Methods

This was a mixed-methods study that used quantitative survey data and qualitative data from focus groups and interviews with informal caregivers enrolled in a Web-based peer support intervention to explore their use and perceptions of the intervention. The intervention was delivered via a website that featured interest groups organized around specific topics, webinars, webchats, and messaging functionality and was moderated by professionally trained peers. This study occurred in the context of a quasi-experimental outcome evaluation of the intervention, where intervention participants were compared with a group of military caregivers who were not enrolled in the intervention.

Results

Survey findings indicated that caregivers used the website infrequently, with 60.7% (128/211) visiting the website once a month or less, and passively, with a minority (32/144, 22.2%) of users (ie, those who had visited the website at least once during the past 3 months, N=144) posting comments or links to the network. Nonetheless, most users (121/144, 84.0%) endorsed moderate or greater satisfaction with the website on the survey, and focus group and interview participants reported benefiting sufficiently from passive use of the website (eg, reading posts). Quantitative and qualitative findings suggested that users viewed the website primarily as a source of informational support. Among 63.2% (91/144) of users who completed the survey, the most commonly reported network-related activity was obtaining information from the network’s resource library, and focus group and interview participants viewed the network primarily as an informational resource. Focus group and interview participants expressed an unmet need for emotional support and the desire for a more personal touch in the forms of more active engagement with other caregivers in the network and the creation of local, in-person support groups for caregivers.

Conclusions

These findings suggest that Web-based peer support interventions may lend themselves better to the provision of informational (vs emotional) support and may need to be supplemented by in-person peer support groups to better meet caregivers’ needs for emotional support.

Prevalence of Prenatal Depression Symptoms Among 2 Generations of Pregnant Mothers: The Avon Longitudinal Study of Parents and Children

IMPORTANCE

Depression during pregnancy (prenatal depression) is common and has important consequences for mother and child. Evidence suggests an increasing prevalence of depression, especially in young women. It is unknown whether this is reflected in an increasing prevalence of prenatal depression.

OBJECTIVE

To compare the prevalence of depression during pregnancy in today's young mothers with their mothers' generation.

DESIGN, SETTING, AND PARTICIPANTS

In a longitudinal cohort study, we compared prenatal depressive symptoms in 2 generations of women who participated in the Avon Longitudinal Study of Parents and Children. Participants were the original mothers (recruited when they were pregnant) and their female offspring, or female partners of male offspring, who became pregnant. Both groups were limited to the same age range (19-24 years). The first generation of pregnancies occurred in 1990 to 1992 (n = 2390) and the second in 2012 to 2016 (n = 180). In both generations, women were born in the same geographical area (southwest England).

MAIN OUTCOMES AND MEASURES

Depressed mood measured prenatally using the Edinburgh Postnatal Depression Scale in self-reported surveys in both generations. A score of 13 or greater on a scale of 0 to 30 indicated depressed mood.

RESULTS

Of 2390 pregnant women in the first generation who were included in analysis (mean [SD] age, 22.1 [2.5] years), 408 (17%) had high depressive symptom scores (≥13). Of 180 pregnant women in the second generation who were included in the analysis (mean [SD] age, 22.8 [1.3] years), 45 (25%) had high depressive symptom scores. Having high depressive symptom scores was more common in the second generation of young pregnant women than in their mothers' generation (relative risk, 1.51; 95% CI, 1.15-1.97), with imputation for missing confounding variable data and adjustment for age, parity, education, smoking, and body mass index not substantially changing this difference. Results were essentially the same when analyses were restricted to the 66 mother-offspring pairs. Maternal prenatal depression was associated with daughters' prenatal depression (relative risk, 3.33; 95% CI, 1.65-6.67).

CONCLUSIONS AND RELEVANCE

In this unique study of 2 generations of women who answered identical questionnaires in pregnancy, evidence was found that depressed mood may be higher in young pregnant women today than in their mothers' generation. Because of the multiple and diverse consequences of prenatal depression, an increase in prevalence has important implications for families, health care professionals, and society.

Active public Facebook use and adolescents' feelings of loneliness: Evidence for a curvilinear relationship

Inconsistent results have been reported concerning the relationships between SNS usage and loneliness. The current two-wave panel study with a one year interval examined the possibility of reciprocal and curvilinear relationships between active public Facebook use and adolescents' social/emotional loneliness. Belgian adolescents from fifteen high schools participated (N = 1188, 55% male). The results showed a U-shaped relationship between (1) active Facebook use and social/emotional loneliness and (2) emotional loneliness and active Facebook use. Specifically, active Facebook use predicted decreased social/emotional loneliness among low to moderate users, while among heavy users, increased levels of social/emotional loneliness were predicted by active Facebook use. Emotional loneliness predicted higher active Facebook use among lonely adolescents. At the same time, emotional loneliness predicted decreased active Facebook use among adolescents who did not feel lonely. These findings stress to consider different types of loneliness, and reciprocal and curvilinear relationships in future social media research.

Social Media Use and Access to Digital Technology in US Young Adults in 2016

BACKGROUND

In 2015, 90% of US young adults with Internet access used social media. Digital and social media are highly prevalent modalities through which young adults explore identity formation, and by extension, learn and transmit norms about health and risk behaviors during this developmental life stage.

OBJECTIVE

The purpose of this study was to provide updated estimates of social media use from 2014 to 2016 and correlates of social media use and access to digital technology in data collected from a national sample of US young adults in 2016.

METHODS

Young adult participants aged 18-24 years in Wave 7 (October 2014, N=1259) and Wave 9 (February 2016, N=989) of the Truth Initiative Young Adult Cohort Study were asked about use frequency for 11 social media sites and access to digital devices, in addition to sociodemographic characteristics. Regular use was defined as using a given social media site at least weekly. Weighted analyses estimated the prevalence of use of each social media site, overlap between regular use of specific sites, and correlates of using a greater number of social media sites regularly. Bivariate analyses identified sociodemographic correlates of access to specific digital devices.

RESULTS

In 2014, 89.42% (weighted n, 1126/1298) of young adults reported regular use of at least one social media site. This increased to 97.5% (weighted n, 965/989) of young adults in 2016. Among regular users of social media sites in 2016, the top five sites were Tumblr (85.5%), Vine (84.7%), Snapchat (81.7%), Instagram (80.7%), and LinkedIn (78.9%). Respondents reported regularly using an average of 7.6 social media sites, with 85% using 6 or more sites regularly. Overall, 87% of young adults reported access or use of a smartphone with Internet access, 74% a desktop or laptop computer with Internet access, 41% a tablet with Internet access, 29% a smart TV or video game console with Internet access, 11% a cell phone without Internet access, and 3% none of these. Access to all digital devices with Internet was lower in those reporting a lower subjective financial situation; there were also significant differences in access to specific digital devices with Internet by race, ethnicity, and education.

CONCLUSIONS

The high mean number of social media sites used regularly and the substantial overlap in use of multiple social media sites reflect the rapidly changing social media environment. Mobile devices are a primary channel for social media, and our study highlights disparities in access to digital technologies with Internet access among US young adults by race/ethnicity, education, and subjective financial status. Findings from this study may guide the development and implementation of future health interventions for young adults delivered via the Internet or social media sites.
