社交媒体使用与错失焦虑的关系：一项元分析

社交媒体使用与错失焦虑均是当下生活中较为常见的现象, 诸多研究探讨了两者间的内在联系, 但研究结果却存在很大差异。为明确两者之间的整体关系, 以及产生分歧的原因, 对检索后获得的65项研究(70个独立样本)使用随机效应模型进行了元分析。结果发现：社交媒体使用与错失焦虑存在显著正相关(r = 0.38, 95% CI [0.34, 0.41]); 二者的相关强度受社交媒体使用测量指标和社交媒体类型的调节, 但不受性别、年龄、错失焦虑测量工具和个体主义指数的调节。结果一定程度上澄清了大众传播的社会认知理论和数字恰到好处假说的争论, 表明社交媒体使用程度越高的人往往也会伴随着较高水平的错失焦虑。防止社交媒体过度使用, 尤其是引导大众合理使用以图像为中心并且开放度较高的社交媒体有助于错失焦虑的缓解。     

The relationship between dysfunctional metacognitive beliefs and problematic social networking sites use

Social networking sites (SNSs) enrol new subscribers each day. However, problematic SNS use has undesirable effects on psychological functioning. Therefore, it is important to identify the factors that contribute to the development of problematic SNS use. Very few studies have focused on revealing the underlying mechanisms of problematic SNS use. Although many past studies have examined the relationship between metacognitive beliefs and Internet addiction, the association between metacognitive beliefs and problematic SNS use has not been adequately explored. In this study, we aimed to explore the association between metacognitive beliefs and problematic SNS use among young adults. A total of 308 individuals participated in this study. A socio-demographic data form, the Metacognitions Questionnaire-30 (MCQ-30), and Social Media Addiction Scale (SMAS) were administered. Group comparisons were performed using multivariate analysis of covariance. Pearson's correlational and multiple linear regression analyses were conducted to examine the associations between metacognitive beliefs and problematic SNS use. The SNS addicts scored higher in all of the SMAS assessments. When compared to non-addicts, SNS addicts obtained higher scores on all the subtests of the SMAS and MCQ-30 except cognitive self-consciousness. The negative beliefs about the uncontrollability and danger of worry, cognitive confidence, and need for control thoughts were associated with SMAS mood modification, relapse and conflict subdimensions. Our findings revealed that dysfunctional metacognitive beliefs are related to problematic SNS use among young adults. These findings indicate that mental health workers should consider the modification of metacognitive beliefs in the treatment of problematic SNS use.     

Psychological mechanisms underlying the relationship between commercial physical activity app use and physical activity engagement

PurposePrevious studies have indicated a relationship between the use of commercial physical activity apps (e.g., Fitbit, Strava) and physical activity engagement. The use of social components of such apps, in particular app-specific communities (connecting with other app users) and existing social networking platforms (e.g., Facebook) have the potential to enhance physical activity. This study aimed to explore the psychological mechanisms underlying the relationship between the use of commercial physical activity apps (and their social components) and physical activity engagement.MethodAn online cross-sectional survey assessed physical activity, use of commercial physical activity apps (and their associated social components), and psychological constructs (social support, self-efficacy, motivation, trait competitiveness, trait social comparison).Results1274 adults aged 18–83 years (M_age = 34.1 ± 13.5 years, 87.6% female) participated. App use was positively associated with physical activity engagement. The relationship between app use and physical activity was fully mediated by social support, self-efficacy, intrinsic motivation and identified regulation. Trait competitiveness, but not trait social comparison, moderated the relationship between app use and physical activity. Most features (e.g., sharing posts, providing or receiving encouragement) of the social components of apps were positively associated with psychological constructs linked to engagement in physical activity. Mediation pathways linking features of existing social networking platforms with physical activity were found. Specifically, sharing posts was linked to higher engagement in physical activity via positive associations with self-efficacy, and receiving encouragement with linked to higher engagement in physical activity via positive associations with both self-efficacy and identified regulation. In addition, engagement in comparisons was associated with lower self-efficacy and higher external regulation, and in turn, lower physical activity.ConclusionsThe relationship between the use of commercial physical activity apps and physical activity is underpinned by social support, self-efficacy and autonomous motivations. The findings highlight the importance of trait competitiveness, which should be taken into consideration when leveraging physical activity apps. Overall, the present study demonstrated that commercial physical activity apps (and their social components) hold great potential to increase physical activity engagement given their associations with psychological constructs strongly linked with physical activity.     

女大学生同性竞争与社交网站发布美化自拍行为的关系：外貌比较的调节作用

为探究女大学生同性竞争与社交网站发布美化自拍行为之间的关系及外貌比较在其中的调节作用,采用同性竞争量表、身体外貌比较问卷和美化自拍量表对463名女大学生进行问卷调查。结果发现：在控制年龄后,女大学生同性竞争可以显著正向预测社交网站美化自拍行为,且这一预测作用受到外貌比较的调节,即只有低外貌比较的女大学生其同性竞争水平可显著预测其美化自拍行为。该结果对理解和干预女大学生的社交网站行为具有一定理论意义和实践意义。     

上行比较影响行为表现—不同类型高自尊的作用

已有研究表明,上行比较对高自尊个体产生积极效应。然而鉴于高自尊包括安全性高自尊和防御性高自尊,有必要在上行比较影响不同任务领域内的行为表现这一观点的基础上探讨高自尊的不同类型对上行比较与行为表现之间关系的影响。两个实验均采用高自尊类型、上行比较和任务领域一致性的2×2×2混合因素设计,不同之处在于其分别采用创造性测验和非创造性的语词测验作为不同领域任务。结果表明,防御性高自尊个体没有像安全性高自尊个体那样采取领域转换策略来修复自我关注,由上行比较所引起的领域转换只对安全性高自尊个体产生积极影响。     

Smile intensity in social networking profile photographs is related to greater scientific achievements

Theory and research indicates that individuals with more frequent positive emotions are better at attaining goals at work and in everyday life. In the current study we examined whether the expression of genuine positive emotions by scientists was positively correlated with work-related accomplishments, defined by bibliometric (e.g. number of citations) and sociometric (number of followers for scholarly updates) indices. Using a sample of 440 scientists from a social networking site for researchers, multiple raters coded smile intensity (full smile, partial smile, or no smile) in publicly available photographs. We found that scientists who presented a full smile had the same quantity of publications yet of higher quality (e.g. citations per paper) and attracted more followers to their updates compared to less positive emotionally expressive peers; results remained after controlling for age and sex. Thin-slicing approaches to the beneficial effects of positive emotionality offer an ecologically valid approach to complement experimental and longitudinal evidence. Evidence linking positive emotional expressions to scientific impact and social influence provides further support for broaden and build models of positive emotions.     

What Goes Up Apparently Needn't Come Down: Asymmetric Predictions of Ascent and Descent in Rankings

In eight studies, we document an upward mobility bias, or a tendency to predict that a rise in rankings is more likely than a decline. This asymmetry was observed in predictions of classroom performance, NBA and NFL standings, business school rankings, and employee performance rankings. The bias was found for entities people care about and want to see improve their standing, as well as entities in which people are not invested. It appears to result from people's tendency to give considerable weight to a focal agent's intentions and motivation, but to give less weight to the intentions of competitors and other factors that would thwart the focal agent's improvement. We show that this bias is most pronounced for implicit incremental theorists, who believe that performance is malleable (and hence assign more weight to intentions and effort). We discuss implications of this asymmetry for decision making and for an understanding of the underdog bias. Copyright © 2015 John Wiley & Sons, Ltd.     

Social Networking Sites: Mediating the Self and its Communities

What do social networking sites reveal about the relation between the self and the community? We conceptualise social networking sites as technologies of the self and the community enabling individuals to self‐present and also objectifying the community's evaluation of individuals (through ‘structures of recognition’ such as page views, friends and lovehearts). We analyse the way in which 37 Scottish adolescents used the social networking site Bebo in nonprescribed and creative ways. First, they challenged the single authorship of profiles by co‐creating multi‐authored profiles. Second, they used creative language to obscure meaning from the preying eyes of parents, teachers and potential employers. We conclude by discussing the simplistic assumptions that Bebo makes about the relation between the self and the community. In contrast, newer social networking sites such as Facebook and Google+ are increasingly enabling people to present different facets of themselves to different communities. How people use social networking sites, and how these sites are developing to attract more users, reveals how the multiplicity of human identity is related to the multiple communities that people participate in.

Analgesic effect of Facebook: Priming with online social networking may boost felt relatedness that buffers against physical pain

Social networking sites (SNSs) are extremely popular for providing users with a convenient platform for acquiring social connections and thereby feeling relatedness. Plenty of literature has shown that mental representations of social support can reduce the perception of physical pain. The current study tested whether thinking about SNS would interfere with users’ perceptions of experimentally induced pain. Ninety‐six undergraduate Facebook users were recruited to participate in a priming‐based experiment. They were randomly assigned to one of the three study conditions (SNS prime, neutral prime, or no prime) via rating the aesthetics of logos. The results showed that participants exposed to SNS primes reported less pain of immersion in hot water than did both control groups (neutral‐ and no‐prime). Felt relatedness mediated the link between SNS primes and diminished pain perceptions. This research provides the first demonstration that thinking about SNS can lower experienced physical pain among Facebook users. Online social networking may serve as an analgesic buffer against pain experience than previously thought. The SNS‐enabled analgesia has far reaching implications for pain relief applications and the enhancement of well‐being in human‐interaction techniques.
