Social networking sites (SNSs) provide users with an efficient interface for distributing information, such as photos or wall posts, to many others simultaneously. We demonstrated experimentally that this type of indiscriminate one-to-many (i.e., monologue) communication may induce self-focused attention and thereby impair perspective taking. The present study used multiple paradigms to explore the link between engaging in online one-to-many communication and a decrease in perspective taking. Experiment 1 revealed that Facebookers who published a personal photo to the public or their friends were less likely to adopt another person’s visual perspective than were those in the control group. Experiment 2 showed that Facebookers who engaged in indiscriminate one-to-many wall posting were more likely than those in the control group to rely heavily on their own perspectives. A state of self-focus, as measured by greater Stroop interference in naming the color of self-relevant versus neutral words, mediated the detrimental effect of indiscriminate one-to-many communication on cognitive perspective taking. These findings suggest that indiscriminate one-to-many communication on SNSs may promote public self-focus, leading to self-referential processing when making social judgments. Online monologue communication may be more harmful to perspective taking than previously understood.

This study aimed to systematically review the use of social networking sites (SNSs) from an older adult perspective (all papers had an average sample age of 65+ and samples ranged in age from 50 to 98). Characteristics of older adult SNS users, incentives and disincentives for use, and the relationship between SNS use, wellbeing and cognitive function were explored. From a systematic search, 21 papers met inclusion criteria and were subjected to a quality review. Paper quality was often low or medium, as rated by a standard quality assessment framework. Results indicated that older adult SNS users were more likely to have particular characteristics, including being female and younger. The main incentive for use was to maintain contact with family and friends. Disincentives included privacy concerns and lack of perceived usefulness. The relationship between SNS use, wellbeing and cognitive function was inconclusive. SNS use is a multi-dimensional phenomenon that needs to be understood in the context of broader communication practices, individuals’ social relationships, and individual preferences and characteristics.

An overarching reason why carers do not utilise support services is that many people who perform care-giving do not necessarily self-identify as a carer. Understanding the development of carer identities is therefore crucial for the utilisation of different carer-focused health services. This study arose from the European Union-funded INNOVAGE project and aimed to describe how older carers conceptualise and understand their identity as carers on a Swedish online social forum. Theoretically the study adopts a constructionist approach and the method of netnography was applied. The findings reveal that a change in self-perception occurs in the process through which a carer role is acquired. The presence or absence of recognition for the older carers’ capacity, knowledge and life situation is seen as filtered through the needs of the care recipient, making the carer identity into an invisible self. This is not least the case when the identity is constructed in alliance with conceptual and moral obligations found within a marital discourse. Nevertheless, the opportunity for online communication may help to create a virtual space of social recognition through which different experiences attached to caring can be discussed. The significance of online communication is here understood as the possibility it presents for carers to be recognised by other carers. It is a process through which an invisible self can become visible.

The repertoire of political participation in democratic societies is expanding rapidly and covers such different activities as voting, demonstrating, volunteering, boycotting, blogging, and flash mobs. Relying on a new method for conceptualizing forms and modes of participation we show that a large variety of creative, expressive, individualized, and digitally enabled forms of participation can be classified as parts of the repertoire of political participation. Results from an innovative survey with a representative sample of the German population demonstrate that old and new forms are systematically integrated into a multi-dimensional taxonomy covering (1) voting, (2) digitally networked participation, (3) institutionalized participation, (4) protest, (5) civic participation, and (6) consumerist participation. Furthermore, the antecedents of consumerist, civic, and digitally networked participation, are very similar to those of older modes of participation such as protest and institutionalized participation. Whereas creative, expressive, and individualized modes appear to be expansions of protest activities, digitally networked forms clearly establish a new and distinct mode of political participation that fits in the general repertoire of political participation.

Unhealthy eating behaviour and excess body weight have been related to sedentary behaviour, particularly screen time, in adolescents; however, little is known about their associations with the use of social networking sites (SNS). We investigated the associations between time spent using SNS and unhealthy eating behaviours (including breakfast skipping, consumption of sugar-sweetened beverages (SSB) and energy drinks) and body weight in adolescents. Data on 9858 students (mean age: 15·2 (sd 1·9) years) in grades 7 through 12 were derived from the 2013 cycle of the Ontario Student Drug Use and Health Survey – a cross-sectional school-based survey of middle and high school students. The majority (81·5 %) of students reported daily use of SNS and an additional 10·7 % reported using them on an irregular basis. Multivariate logistic regression analyses revealed that the use of SNS was associated with increased odds of skipping breakfast (Ptrend<0·01) and consuming SSB (Ptrend<0·01) and energy drinks (Ptrend<0·01) in a dose–response manner with adjustments for age, sex, ethnicity, socio-economic status, tobacco, alcohol and cannabis use as well as BMI. However, there was no evidence of a significant association between use of SNS and BMI before or after adjusting for all the covariates and unhealthy eating behaviours. In conclusion, our results suggest associations between the use of SNS and unhealthy eating behaviours among youth. Given the popularity of SNS, more efforts are needed to better understand the impact of social networks on eating behaviours and risk of excess weight.

Voters and political candidates increasingly use social networking sites (SNSs) such as Facebook. This study uses data from an online posttest-only experiment (N = 183) in analyzing how exposure to supportive or challenging user comments on a fictional candidate's Facebook page influenced participants’ perceptions of and willingness to vote for the candidate, as well as whether candidate replies to each type of user comments affected these outcomes. Participants who viewed a page with supportive comments and “likes” reported more favorable perceptions of and greater support for the candidate, relative to participants who viewed a page with challenging comments. Thus, the appearance of interactivity between a candidate and other users on the candidate's Facebook page can shape the responses of those viewing the page. However, exposure to candidate replies to either supportive or challenging comments did not lead to significantly more favorable perceptions or a greater likelihood of voting for the candidate.

Facebook has become a very popular social networking platform today, particularly among adolescents and young adults, profoundly changing the way they communicate and interact. However, some reports have indicated that excessive Facebook use might have detrimental effects on mental health and be associated with certain psychological problems. Because previous findings on the relationship between Facebook addiction and depression were not unambiguous, further investigation was required. The main objective of our study was to examine the potential associations between Internet use, depression, and Facebook intrusion. A total of 672 Facebook users took part in the cross-sectional study. The Facebook Intrusion Questionnaire and the Center for Epidemiologic Studies Depression Scale were used. For collecting the data, the snowball sampling procedure was used. We showed that depression can be a predictor of Facebook intrusion. Our results provides additional evidence that daily Internet use time in minutes, gender, and age are also predictors of Facebook intrusion: that Facebook intrusion can be predicted by being male, young age, and an extensive number of minutes spent online. On the basis of this study, it is possible to conclude that there are certain demographic – variables, such as age, gender, or time spent online – that may help in outlining the profile of a user who may be in danger of becoming addicted to Facebook. This piece of knowledge may serve for prevention purposes.

Technology and social networking tools and sites are changing the way young people build and maintain their social connections with others (Boyd & Ellison, 2008). This study utilised a new measure, The Self in a Social Context, Virtual Connectedness subscale (SSC-VC subscale), to examine the effects of social networking tools and sites on social and emotional wellbeing among 1,037 Australian young people aged 11–18 years. A maximum likelihood factor analysis identified three strong factors: Fit In (α = .81), Public Self (α = .79) and Connected Self (α = .83). Significant main effects were revealed for the number of times students checked their Facebook F(12, 2415) = 13.8, p < .001, and for gender, F(3, 913) = 10.8, p < .001, but no interaction effect was found. Univariate tests also revealed a significant difference for Frequency of checking Facebook, F(4, 915), = 4.98, and for Gender, F(1, 915), = 46.92, p < .001 on the dependent variable of Emotional Difficulties. These findings suggest that social networking sites, though used differently by males and females, provide an important forum for building social connections across groups.

Introduction: This study examined members of health issue-specific social networking sites (SNSs) for smoking cessation, applying Social Identity Theory (SIT).

Aims: The aim of the study was to test the relationships between perceived verbal, affective, cognitive and physical intimacy on the sites, participation level, social identification and smoking cessation self-efficacy.

Methods: An online questionnaire (N = 252) assessed members of SNSs for smoking cessation. Confirmatory factor analysis (CFA), structural equation modelling (SEM), mediation analysis, MANOVA and ANOVA tests were used to test the hypotheses.

Results/Findings: Verbal, affective, cognitive and physical intimacy significantly predicted participation; participation significantly predicted social identification and smoking cessation self-efficacy; and social identification mediated between participation and smoking cessation self-efficacy. Active participants and lurkers differed significantly on perceived verbal, affective, cognitive and physical intimacy, social identification, and smoking cessation self-efficacy.

Conclusions: Health issue-specific SNSs for smoking cessation have a positive impact on members’ smoking cessation self-efficacy. Higher perceived intimacy facilitates participation online, which in turn influences smoking cessation self-efficacy, with social identification mediating this relationship.

Background: Social networking sites can be beneficial for senior citizens to promote social participation and to enhance intergenerational communication. Particularly for older adults with impaired mobility, social networking sites can help them to connect with family members and other active social networking users. The aim of this systematic review is to give an overview of existing scientific literature on social networking in older users.

Methods: Computerized databases were searched and 105 articles were identified and screened using exclusion criteria. After exclusion of 87 articles, 18 articles were included, reviewed, classified, and the key findings were extracted. Common findings are identified and critically discussed and possible future research directions are outlined.

Results: The main benefit of using social networking sites for older adults is to enter in an intergenerational communication with younger family members (children and grandchildren) that is appreciated by both sides. Identified barriers are privacy concerns, technical difficulties and the fact that current Web design does not take the needs of older users into account.

Conclusions: Under the conditions that these problems are carefully addressed, social networking sites have the potential to support today's and tomorrow's communication between older and younger family members.
