线上社交焦虑指个体在社交媒体交往情境中感知到的紧张和恐惧等人际负性体验,包含隐私担忧、交往焦虑和负面评价恐惧三个方面。线上社交焦虑可以通过质性分析法、实验诱发法和问卷测量法进行研究。线上社交焦虑既会受到社交媒体自身特点、个体特征因素、网络欺凌和文化因素的影响,还会对个体的心理与行为产生后效。未来研究者需要开发有效的本土化测量工具、探索其形成和作用机制、关注线上社交焦虑悖论以及推动对其干预。  相似文献

Abstract

There is increasing evidence that low family socioeconomic status (SES) not only is a social issue, but also is a precursor to addiction to social media and other technologies. The authors investigated the relationship between family SES, stress, impulsiveness and inhibitory control, and social media addiction among Chinese female college students. The findings revealed that in lower-SES families, increased social media addiction was associated with reduced inhibitory control and increased stress and impulsiveness. A structural equation model was used to examine the mediation model hypothesis, and the results confirmed the mediating role of no-planning impulsiveness and inhibitory control between family educational level and social media addiction among Chinese female college students. These findings demonstrate the importance of reducing impulsiveness and improving inhibitory control for preventing social media addiction in female college students of low SES. Future studies are required to confirm precursors to social media addiction, elucidate causal mechanisms, and support the explanatory model of social media addiction.  相似文献

Objective: This study examined the interactive role of affectivity and stress in substance use severity among ethnic minority, emerging adult males, using linguistic indicators of affect obtained through social media.

Method: Participants were 119 emerging adult, ethnic minority males (ages 18–25) who provided access to their mobile phone text messaging and Facebook activity for 6-months. Computerized text analysis (LIWC2015) was used to obtain linguistic indices of positive and negative affect from texts and Facebook posts. The Perceived Stress Scale was used to measure stress, and items from the Drug Abuse Screening Test were used to measure substance use severity.

Results: Generalized estimating equations showed that higher negative affect in texts was associated with greater substance use severity. Stress moderated the relationship between positive affect expressed in Facebook posts and substance use such that higher positive affect in Facebook posts was associated with less substance use at higher stress and greater substance use at lower stress.

Conclusions: Findings highlight the complexities of interactions between stress and affectivity. Findings could inform development of substance use interventions for young males that employ social technologies.  相似文献

Although many studies have investigated individual differences in online social networking, few have examined the recent and rapidly popularized social phenomenon of the “selfie” (a selfportrait photograph of oneself). In two studies with a pooled sample of 1296 men and women, we tested the prediction that individuals who score high on four narcissism sub-scales (Self-sufficiency, Vanity, Leadership, and Admiration Demand) will be more likely to post selfies to social media sites than will individuals who exhibit low narcissism. We examined three categories of selfies: own selfies; selfies with a romantic partner; and group selfies, controlling for non-selfie photographs. Women posted more selfies of all types than did men. However, women’s selfie-posting behavior was generally unrelated to their narcissism scores. In contrast, men’s overall narcissism scores positively predicted posting own selfies, selfies with a partner, and group selfies. Moreover, men’s Vanity, Leadership, and Admiration Demand scores each independently predicted the posting of one or more types of selfies. Our findings provide the first evidence that the link between narcissism and selfie-posting behavior is comparatively weak among women than men, and provide novel insight into the social motivations and functions of online social networking.  相似文献

Status updates are one of the most popular features of Facebook, but few studies have examined the traits and motives that influence the topics that people choose to update about. In this study, 555 Facebook users completed measures of the Big Five, self-esteem, narcissism, motives for using Facebook, and frequency of updating about a range of topics. Results revealed that extraverts more frequently updated about their social activities and everyday life, which was motivated by their use of Facebook to communicate and connect with others. People high in openness were more likely to update about intellectual topics, consistent with their use of Facebook for sharing information. Participants who were low in self-esteem were more likely to update about romantic partners, whereas those who were high in conscientiousness were more likely to update about their children. Narcissists’ use of Facebook for attention-seeking and validation explained their greater likelihood of updating about their accomplishments and their diet and exercise routine. Furthermore, narcissists’ tendency to update about their accomplishments explained the greater number of likes and comments that they reported receiving to their updates.  相似文献

Research on the association between social anxiety and social media usage remains inconclusive: despite the preference for computer-mediated communication there is currently no clear empirical support for social anxiety being associated with longer duration of social media use. Self-report measures for social anxiety that are adapted for the context of social media could facilitate further research. The current study aimed to develop a Swedish version of the recently developed Social Anxiety Scale for Social Media Users (SAS-SMU), evaluate its psychometric properties, and explore associations between different uses of social media and social anxiety. Three factors were retained for SAS-SMU with excellent internal consistency. SAS-SMU evidenced convergent validity with measures of social anxiety, negative convergent validity with satisfaction with life, and divergent validity with measures of obsessive-compulsive disorder, depression and generalized anxiety disorder. Results indicated that higher levels of social anxiety were associated with passive and active use as well as longer duration of social media use in general, which is at odds with a previous study where passive use remained the only significant predictor for social anxiety.  相似文献

Fact-checking has become an important feature of the modern media landscape. However, it is unclear what the most effective format of fact-checks is. Some have argued that simple retractions that repeat a false claim and tag it as false may backfire because they boost the claim's familiarity. More detailed refutations may provide a more promising approach, but may not be feasible under the severe space constraints associated with social-media communication. In two experiments, we tested whether (1) simple ‘false-tag’ retractions can indeed be ineffective or harmful; and (2) short-format (140-character) refutations are more effective than simple retractions. Regarding (1), simple retractions reduced belief in false claims, and we found no evidence for a familiarity-driven backfire effect. Regarding (2), short-format refutations were found to be more effective than simple retractions after a 1-week delay but not a one-day delay. At both delays, however, they were associated with reduced misinformation-congruent reasoning.  相似文献
