Food-Related Online Media (Mukbang and Cookbang) Exposure and Dietary Risk Behaviors in Korean Adolescents.

BACKGROUND: Studies have shown that prolonged smartphone use is associated with dietary risk behaviors among adolescents. However, little is known about whether the exposure to food-related online media contents, such as mukbang (eating broadcast) and cookbang (cooking broadcast), is associated with unhealthy dietary behaviors, independent of overall duration of smartphone use. OBJECTIVES: This study investigated the associations between the frequency of mukbang/cookbang watching and dietary risk behaviors among Korean adolescents, using nationally representative survey data. METHODS: In this cross-sectional study, we examined the data from 50,044 middle and high school students in the Korea Youth Risk Behavior Web-based Survey 2022. Participants reported their frequency of mukbang/cookbang watching, mean duration of smartphone use, frequency of breakfast eating, frequency of nighttime eating, and intakes of fast foods, sugar-sweetened beverages (SSBs), and high-caffeine drinks. We performed multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between mukbang/cookbang watching and dietary risk behaviors, accounting for complex survey sampling and adjusting for potential confounders. RESULTS: Frequent mukbang/cookbang watching (≥5 times/wk compared with never) was positively associated with dietary risk behaviors, including frequent breakfast skipping (OR: 1.20; 95% CI: 1.13, 1.28), frequent nighttime eating (OR: 1.43; 95% CI: 1.33, 1.54), and frequent intakes of fast foods (OR: 1.69; 95% CI: 1.58, 1.80), SSBs (OR: 1.47; 95% CI: 1.30, 1.66), and high-caffeine drinks (OR: 1.41; 95% CI: 1.33, 1.50), adjusting for duration of smartphone use. All mukbang/cookbang viewers, including those who perceived that mukbang/cookbang videos had "no influence" on their dietary behavior, had higher prevalence of dietary risk behaviors than nonviewers (perceived "no influence" compared with nonviewers-OR: 1.18; 95% CI: 1.10, 1.26, breakfast skipping; OR: 1.15; 95% CI: 1.06, 1.24, nighttime eating; OR: 1.40; 95% CI: 1.30, 1.50, fast foods; OR: 1.22; 95% CI: 1.07, 1.38, SSBs; OR: 1.28; 95% CI: 1.20, 1.37, high-caffeine drinks). CONCLUSIONS: Our findings suggest that frequent mukbang/cookbang watching may be associated with unhealthy dietary behaviors among Korean adolescents.

#junkfluenced: the marketing of unhealthy food and beverages by social media influencers popular with Canadian children on YouTube, Instagram and TikTok.

BACKGROUND: Marketing of unhealthy foods to children on digital media significantly impacts their dietary preferences and contributes to diet-related noncommunicable diseases. Canadian children spend a significant amount of time on digital devices and are frequently exposed to unhealthy food marketing on social media, including by influencers with celebrity status who endorse products. This study aimed to examine the frequency, healthfulness, and power of unhealthy food marketing in posts by influencers popular with Canadian children on YouTube, Instagram and TikTok. METHODS: The top 9 influencers popular amongst Canadian children aged 10-12 years were identified from the 2021 International Food Policy Study Youth Survey. A total of 2,232 Instagram, YouTube and TikTok posts made by these influencers between June 1st 2021 and May 31st 2022 were examined for instances of food marketing. Food products/brands were identified and frequencies were calculated for the number of posts promoting food products/brands, posts promoting products/brands classified as less healthy according to Health Canada's Nutrient Profile Model (2018) and marketing techniques utilized. RESULTS: YouTube had the highest average rate of food marketing instances per post, at a rate of 1 food marketing instance every 0.7 posts, while TikTok and Instagram had instances every 10.2 posts and 19.3 posts, respectively. Overall, fast food restaurants was the most promoted food category (21%), followed by regular soft drinks (13%), snacks (11%), candy and chocolate (11%) and water (8%). The most frequently used marketing techniques were appeals to fun/cool (37%), the use of songs or music (28%) and the product being consumed (25%). In terms of healthfulness, 83% of the products/brands (87% of brands and 82% of products) promoted were classified as less healthy. CONCLUSIONS: Social media influencers play a substantial role in promoting unhealthy food products to children, primarily fast food items. Given the significant impact of such marketing on children, there is a need for ongoing government-led monitoring, and it is crucial to include social media and influencer marketing in marketing restrictions targeting children in Canada to safeguard this vulnerable demographic.

Prevalence and factors associated with digital addiction among students taking university entrance tests: a GIS-based study.

BACKGROUND: The surge in digital media consumption, coupled with the ensuing consequences of digital addiction, has witnessed a rapid increase, particularly after the initiation of the COVID-19 pandemic. Despite some studies exploring specific technological addictions, such as internet or social media addiction, in Bangladesh, there is a noticeable gap in research focusing on digital addiction in a broader context. Thus, this study aims to investigate digital addiction among students taking the university entrance test, examining its prevalence, contributing factors, and geographical distribution using GIS techniques. METHODS: Data from a cross-sectional survey were collected from a total of 2,157 students who were taking the university entrance test at Jahangirnagar University, Bangladesh. A convenience sampling method was applied for data collection using a structured questionnaire. Statistical analyses were performed with SPSS 25 Version and AMOS 23 Version, whereas ArcGIS 10.8 Version was used for the geographical distribution of digital addiction. RESULTS: The prevalence of digital addiction was 33.1% (mean score: 16.05 ± 5.58). Those students who are attempting the test for a second time were more likely to be addicted (42.7% vs. 39.1%), but the difference was not statistically significant. Besides, the potential factors predicted for digital addiction were student status, satisfaction with previous mock tests, average monthly expenditure during the admission test preparation, and depression. No significant difference was found between digital addiction and districts. However, digital addiction was higher in the districts of Manikganj, Rajbari, Shariatpur, and Chittagong Hill Tract areas, including Rangamati, and Bandarban. CONCLUSIONS: The study emphasizes the pressing need for collaborative efforts involving educational policymakers, institutions, and parents to address the growing digital addiction among university-bound students. The recommendations focus on promoting alternative activities, enhancing digital literacy, and imposing restrictions on digital device use, which are crucial steps toward fostering a healthier digital environment and balanced relationship with technology for students.

Pixels and perception: Mapping the association between digital media and psychotic-like experiences in adolescents.

INTRODUCTION: Psychotic-like experiences (PLEs) during adolescence can lead to psychotic disorders. Digital media usage has been suggested to link to PLEs, but research is limited on how different types of screen exposure may differentially relate to PLEs over time. This study aimed to examine longitudinal associations between screen usage patterns and PLEs in adolescents. METHODS: Participants comprised 11,876 adolescents assessed annually from ages 9-12 years as part of the Adolescent Brain Cognitive Development study (ABCD). Screen usage (TV, video games, online video, social media, texting, video chat) and PLEs were assessed via self-report. Longitudinal network analysis models were estimated to examine connections between screen usage types and PLEs across three time points. RESULTS: Two clusters were formed, including digital media for socializing (e.g., social media/texting/video chat) and digital media for entertainment (e.g., online video/video games/TV). Texting and online video(s) had the highest centrality at each time point, suggesting importance in the network. PLE symptoms of hallucinations and concentration difficulties exhibited higher centrality than other symptoms. Online video and TV were influential bridges between screen usage and PLEs. Network structure significantly differed between ages 9-10 and 10-12 years, but global strength was unchanged over time. DISCUSSION: Results highlight the importance of understanding the associations between specific screen usage types and PLE symptoms. Texting and online video usage appear most influential in the development of adolescent PLEs over time. Findings can inform targeted interventions to promote healthy screen habits and reduce PLEs in at-risk youth.

Food marketing on digital platforms: what do teens see?

OBJECTIVE: Given the aggressive marketing of foods and beverages to teenagers on digital platforms, and the paucity of research documenting teen engagement with food marketing and its persuasive content, the objective of this study is to examine what teenagers see as teen-targeted food marketing on four popular digital platforms and to provide insight into the persuasive power of that marketing. DESIGN: This is an exploratory, participatory research study, in which teenagers used a special mobile app to capture all teen-targeted food and beverage marketing they saw on digital media for 7 d. For each ad, participants identified the brand, product and specific appeals that made it teen-targeted, as well as the platform on which it was found. SETTING: Online (digital media) with teenagers in Canada. PARTICIPANTS: Two hundred and seventy-eight teenagers, aged 13-17 years, were participated. Most participants were girls (63 %) and older teenagers (58 % aged 16-17 years). RESULTS: Participants captured 1392 teen-targeted food advertisements from Instagram, Snapchat, TikTok and YouTube. The greatest number of food marketing examples came from Instagram (46 %) (with no difference across genders or age), while beverages (28·7 %), fast food (25·1 %) and candy/chocolate were the top categories advertised. When it comes to persuasive power, visual style was the top choice across all platforms and participants, with other top techniques (special offer, theme and humour), ranking differently, depending on age, gender and platform. CONCLUSIONS: This study provides insight into the nature of digital food marketing and its persuasive power for teenagers, highlighting considerations of selection and salience when it comes to examining food marketing and monitoring.

Child and adolescent exposure to unhealthy food marketing across digital platforms in Canada.

BACKGROUND: Children and adolescents are exposed to a high volume of unhealthy food marketing across digital media. No previous Canadian data has estimated child exposure to food marketing across digital media platforms. This study aimed to compare the frequency, healthfulness and power of food marketing viewed by children and adolescents across all digital platforms in Canada. METHODS: For this cross-sectional study, a quota sample of 100 youth aged 6-17 years old (50 children, 50 adolescents distributed equally by sex) were recruited online and in-person in Canada in 2022. Each participant completed the WHO screen capture protocol where they were recorded using their smartphone or tablet for 30-min in an online Zoom session. Research assistants identified all instances of food marketing in the captured video footage. A content analysis of each marketing instance was then completed to examine the use of marketing techniques. Nutritional data were collected on each product viewed and healthfulness was determined using Health Canada's 2018 Nutrient Profile Model. Estimated daily and yearly exposure to food marketing was calculated using self-reported device usage data. RESULTS: 51% of youth were exposed to food marketing. On average, we estimated that children are exposed to 1.96 marketing instances/child/30-min (4067 marketing instances/child/year) and adolescents are exposed to 2.56 marketing instances/adolescent/30-min (8301 marketing instances/adolescent/year). Both children and adolescents were most exposed on social media platforms (83%), followed by mobile games (13%). Both age groups were most exposed to fast food (22% of marketing instances) compared to other food categories. Nearly 90% of all marketing instances were considered less healthy according to Health Canada's proposed 2018 Nutrient Profile Model, and youth-appealing marketing techniques such as graphic effects and music were used frequently. CONCLUSIONS: Using the WHO screen capture protocol, we were able to determine that child and adolescent exposure to the marketing of unhealthy foods across digital media platforms is likely high. Government regulation to protect these vulnerable populations from the negative effects of this marketing is warranted.

Association of physical activity and screen time with cardiovascular disease risk in the Adolescent Brain Cognitive Development Study.

BACKGROUND: According to the Physical Activity Guidelines Advisory Committee Scientific Report, limited evidence is available on sedentary behaviors (screen time) and their joint associations with physical activity (steps) for cardiovascular health in adolescence. The objective of this study was to identify joint associations of screen time and physical activity categories with cardiovascular disease (CVD) risk factors (blood pressure, hemoglobin A1c, cholesterol) in adolescence. METHODS: This study analyzed data from the Adolescent Brain Cognitive Development (ABCD) Study, comprising a diverse sample of 4,718 U.S. adolescents aged 10-15 years between 2018 and 2021. Steps were measured by a Fitbit wearable device and levels were categorized as low (1,000-6,000), medium (> 6,000-12,000), and high (> 12,000) averaged daily step counts. Self-reported recreational screen time hours per day were classified as low (0-4), medium (> 4-8), and high (> 8) hours per day. CVD risk factors including blood pressure, hemoglobin A1c, and cholesterol (total and HDL) were measured. RESULTS: The analytical sample averaged 6.6 h of screen time per day and 9,722 steps per day. In models including both screen time and steps, the high screen time category was associated with a 4.27 higher diastolic blood pressure percentile (95% CI 1.83-6.73) and lower HDL cholesterol (B= -2.85, 95% CI -4.77 to -0.94 mg/dL) compared to the low screen time category. Medium (B = 3.68, 95% CI 1.24-6.11) and low (B = 7.64, 95% CI 4.07-11.20) step categories were associated with higher diastolic blood pressure percentile compared to the high step category. The medium step category was associated with lower HDL cholesterol (B= -1.99, 95% CI -3.80 to -0.19 mg/dL) compared to the high step category. Findings were similar when screen time and step counts were analyzed as continuous variables; higher continuous step count was additionally associated with lower total cholesterol (mg/dL). CONCLUSIONS: Combinations of low screen time and high steps were generally associated with favorable cardiovascular health markers including lower diastolic blood pressure and higher HDL cholesterol, which can inform future adolescent health guidelines.

Greater mobile device-prompted phone pickups are associated with daily parent stress.

AIM: No studies have examined notifications as they relate to parent stress. We aimed to examine associations between objective daily mobile device notifications and pickups with daily parenting stress. METHODS: This was a within- and between-subjects, cross-sectional study that took place from 2020 to 2021. The study occurred during the coronavirus disease of 2019 pandemic. Data were collected in a low-contact home visit. This study included 62 parents of 62 children aged 48-71 months. Parents downloaded a passive sensing app on their Android mobile devices collecting data on duration, device notifications and device pickups. Parents completed an end-of-day stress survey for 4 days. We used random effects models to examine the variation of daily stress with smartphone duration, notification frequency, pickup frequency and device-initiated pickups, adjusting for covariates. RESULTS: Parents were on average 37.3 years old (SD ± 5.7) and were predominantly mothers (82.3%). On average, parents received 293 daily notifications and picked up their phones 93 times. Duration of smartphone use and notification frequency were not associated with daily stress. Device-initiated pickups were associated with daily parent stress. CONCLUSION: When notifications prompted parents to pick up their phones more often, parents experienced greater stress.

Variability and patterns in children's media use and links with language development.

AIM: Media use is widespread and rising, but how often and for what purpose young children use media varies, which has differential impacts on development. Yet little work has measured how and why children under 36 months use digital media or media's consequences for language. METHODS: The current study measures how and why 17- to 30-month-old children use digital media and associations with their language abilities. The amount of use, type of activity and caregiver reasons for children's media use were then compared to the child's vocabulary and mean length of utterance. RESULTS: About 17- to 30-month-old children are primarily exposed to TV/videos over other media forms, which are often used to occupy children. Video time (but not other activities) negatively predicts children's language. The negative impact of videos on vocabulary persists regardless of the reason for use, however, the effect of videos on expressive language may be tempered when videos are used for education or connecting. CONCLUSION: Children under 36 months are using digital media at high rates. What they are doing and why they use media is critical to predict the effect it might have on language development. Further research and anticipatory guidance on the consequences of videos are needed.

Food and non-alcoholic beverage marketing via Fortnite streamers on Twitch: A content analysis.

Food and non-alcoholic beverage (hereafter: food) marketing is prevalent in digital media and predominantly for foods high in fats, salt and/or sugar (HFSS). However, little is known about food marketing in videogame livestreaming platforms - a hybridisation of social and gaming media where individuals can watch influencers (i.e., streamers) play videogames. No studies have explored food cues within the streamed content or content likely to be viewed by adolescents. The current study analysed the food cues in Twitch (the leading videogame livestreaming platform) videos (n = 52, 52h) uploaded to the platform during October 2020-September 2021 by influencers likely to be popular with adolescents. Food cues (n = 133, 2.56 per hour) were coded for exposure (e.g., display type, healthfulness) and power (e.g., presentation) using a World Health Organization (WHO) protocol and the UK Nutrient Profile Model. The majority (70.7%) of cues were HFSS, with energy drinks being the most featured food category (62.4%). Most cues were branded (80.5%) and featured as either product placement (44.4%) or a looping image (40.6%). Influencers were more likely to consume healthy (88.5%) than HFSS items (33.4%). The mean duration of each food cue was 20 min and 25 s per hour. Only 2.3% of cues had an advertising disclosure. This study provides the first empirical assessment of food cues on Twitch in livestreamed content likely to be popular with adolescents and has implications for digital food marketing policy development.

The role of social media in the professional sphere of Finnish registered dietitians.

BACKGROUND: With the widespread use of social media, understanding how healthcare professionals, such as dietitians, utilise these platforms for their work has gained interest. The aim of the current study was to describe how Finnish registered dietitians utilise various social media channels for professional purposes. The study also investigated the perceived social media skills of dietitians. METHODS: A cross-sectional study was conducted using an online survey administered between December 2022 and February 2023. The participants were 107 Finnish registered dietitians who held a master's degree suitable for the profession. The Fisher's exact test was employed for categorical variables, whereas the Kruskal-Wallis test was used for ordinal variables with multiple groups. RESULTS: Out of the 107 participants, 62 (58%) reported using social media for professional purposes. The primary purposes across various social media channels were interaction with colleagues (80%) on Facebook, networking with professionals from other fields (86%) on LinkedIn and general monitoring of the field on Instagram (91%), Twitter (77%) and YouTube (58%). Dietitians' perceived social media skills were found to have a statistically significant relationship with age (p < 0.05) for all channels, except Twitter. CONCLUSIONS: The findings suggest that Finnish dietitians predominantly utilise social media for passive monitoring of the field, rather than actively sharing content with the public. Professional communication tends to take place within their own professional groups. Incorporating social media use into the official job description could serve as an encouraging factor to enhance the professional utilisation of social media among dietitians.

Digital Media Usage Behavior and Its Impact on the Physician-Patient Relationship: Cross-Sectional Study Among Individuals Affected by Psoriasis in Germany.

BACKGROUND: Psoriasis is a chronic skin disorder with a high burden of disease. People affected with psoriasis increasingly use the internet for health-related reasons, especially those with younger age, higher education, and higher disease severity. Despite advantages such as enhancing the individuals' knowledge with the use of digital media for health-related issues, disadvantages were also present such as quality control, and variability in the individuals' health information literacy. While patients with psoriasis within medical settings generally trust physicians over digital media, they commonly withhold their web-based research findings from health care providers. OBJECTIVE: The study aims to (1) identify further factors associated with regular psoriasis-related internet use, (2) rank specific digital media platforms used, and (3) examine digital media within the physician-patient relationship among individuals with and without dermatological treatment. METHODS: A cross-sectional, questionnaire-based study was conducted among individuals with self-reported psoriasis in Germany between September 2021 and February 2022. Participants were recruited via digital media platforms and in person at a University Hospital Department of Dermatology in southern Germany. The questionnaire asked about demographic and medical information, individual psoriasis-related digital media use, and the impact of digital media on the physician-patient relationship. Data were analyzed descriptively, and logistic regression models were performed to assess the factors associated with regular psoriasis-related internet use. RESULTS: Among 321 individuals with a median age of 53 (IQR 41-61) years (nonnormally distributed; females: 195/321), female sex, shorter disease duration, moderate mental burden of disease, and good self-assessed psoriasis-related knowledge were associated with regular psoriasis-related internet use. Of the 188 participants with a mean age of 51.2 (SD 13.9) years (normally distributed) who used digital media 106 (56.4%) usually searched for information on psoriasis-based websites and 98 (52.1%) on search engines, primarily for obtaining information about the disease and therapy options, while social media were less frequently used (49/188, 26.1%). Nearly two-thirds of internet users (125/188) claimed that their physicians did not recommend digital media platforms. About 44% (82/188) of the individuals reported to seek for additional information due to the insufficient information provided by their physician. CONCLUSIONS: This study revealed the importance of digital media in the context of psoriasis, especially among women, individuals with shorter disease duration, and moderate mental disease severity. The lack of physicians' digital media recommendations despite their patients' desire to receive such and being more involved in health-related decisions seems to be a shortcoming within the physician-patient relationships. Physicians should guide their patients on digital media by recommending platforms with evidence-based information, thereby potentially creating an adequate framework for shared decision-making. Future research should focus on strategies to prevent the spread of false information on digital media and address the needs of patients and physicians to enhance health-related digital media offerings.

A Multidimensional Approach for Evaluating Reality in Social Media: Mixed Methods Study.

BACKGROUND: Misinformation is a threat to public health. The effective countering of misinformation may require moving beyond the binary classification of fake versus fact to capture the range of schemas that users employ to evaluate social media content. A more comprehensive understanding of user evaluation schemas is necessary. OBJECTIVE: The goal of this research was to advance the current understanding of user evaluations of social media information and to develop and validate a measurement instrument for assessing social media realism. METHODS: This research involved a sequence of 2 studies. First, we used qualitative focus groups (n=48). Second, building on the first study, we surveyed a national sample of social media users (n=442). The focus group data were analyzed using the constant comparison approach. The survey data were analyzed using confirmatory factor analyses and ordinary least squares regression. RESULTS: The findings showed that social media reality evaluation involves 5 dimensions: falsity, naturality, authenticity, resonance, and social assurance. These dimensions were differentially mapped onto patterns of social media use. Authenticity was strongly associated with the existing global measure of social media realism (P<.001). Naturality, or the willingness to accept artificiality and engineered aspects of social media representations, was linked to hedonic enjoyment (P<.001). Resonance predicted reflective thinking (P<.001), while social assurance was strongly related to addictive use (P<.001). Falsity, the general belief that much of what is on social media is not real, showed a positive association with both frequency (P<.001) and engagement with (P=.003) social media. These results provide preliminary validity data for a social media reality measure that encompasses multiple evaluation schemas for social media content. CONCLUSIONS: The identification of divergent schemas expands the current focus beyond fake versus fact, while the goals, contexts, and outcomes of social media use associated with these schemas can guide future digital media literacy efforts. Specifically, the social media reality measure can be used to develop tailored digital media literacy interventions for addressing diverse public health issues.

Quality of Patient-Centered eHealth Information on Erosive Tooth Wear: Systematic Search and Evaluation of Websites and YouTube Videos.

BACKGROUND: Due to the declining prevalence of dental caries, noncarious tooth defects such as erosive tooth wear have gained increased attention over the past decades. While patients more frequently search the internet for health-related information, the quality of patient-centered, web-based health information on erosive tooth wear is currently unknown. OBJECTIVE: This study aimed to assess the quality of patient-centered, web-based health information (websites and YouTube videos) on erosive tooth wear. METHODS: German-language websites were systematically identified through 3 electronic search engines (google.de, bing.de or yahoo.de, and duckduckgo.com) in September 2021. Eligible websites were independently assessed for (1) technical and functional aspects via the LIDA instrument, (2) readability via the Flesch reading-ease score, (3) comprehensiveness of information via a structured checklist, and (4) generic quality and risk of bias via the DISCERN instrument by 2 different reviewers. An overall quality score (ie, higher scores being favored) generated from all 4 domains was used as the primary outcome. Quality scores from each domain were separately analyzed as secondary outcomes and compared by the Friedman test. The effect of practice-specific variables on quality scores of websites from private dental offices was assessed using generalized linear modeling. Eligible YouTube videos were judged based on (1) the comprehensiveness of information, (2) viewers' interaction, and (3) viewing rate. The comprehensiveness of information was compared between websites and YouTube videos using the Wilcoxon rank-sum test. RESULTS: Overall, 231 eligible websites and 7 YouTube videos were identified and assessed. The median overall quality of the websites was 33.6% (IQR 29.8%-39.2%). Secondary outcome scores amounted to 64.3% (IQR 59.8%-69.0%) for technical and functional aspects, 40.0% (IQR 34.0%-49.0%) for readability, 11.5% (IQR 3.9%-26.9%) for comprehensiveness of information, and 16.7% (IQR 8.3%-23.3%) for generic quality. While the comprehensiveness of information and generic quality received low scores, technical and functional aspects as well as readability resulted in higher scores (both Padjusted<.001). Regarding practice-specific variables, websites from private dental offices outside Germany (P=.04; B=-6.64, 95% CI -12.85 to -0.42) or from dentists who are a dental society member (P=.049; B=-3.55, 95% CI -7.09 to -0.01) resulted in lower readability scores (ie, were more difficult to read), while a shorter time since dentists' examination resulted in higher readability scores (P=.01; B=0.24 per year, 95% CI 0.05-0.43). The comprehensiveness of information from YouTube videos was 34.6% (IQR 13.5%-38.5%). However, the comprehensiveness of information did not vary between websites and YouTube videos (P=.09). Additionally, viewers' interaction (1.7%, IQR 0.7%-3.4%) and viewing rates (101%, IQR 54.6%-112.6%) were low. CONCLUSIONS: The quality of German-language, patient-centered, web-based information on erosive tooth wear was limited. Especially, the comprehensiveness and trustworthiness of the available information were insufficient. Web-based information on erosive tooth wear requires improvement to inform patients comprehensively and reliably.

Retrospecting Digital Media Use, Negative Emotions, and Trust Gaps During the COVID-19 Pandemic in China: Cross-Sectional Web-Based Survey.

BACKGROUND: Retrospecting the trust gaps and their dynamics during the pandemic is crucial for understanding the root causes of postpandemic challenges and offers valuable insights into preparing for future public health emergencies. The COVID-19 pandemic eroded people's trust in strangers and acquaintances, while their trust in family members remained relatively stable. This resulted in 2 trust gaps, namely, the family members-strangers trust gap and the family members-acquaintances trust gap. Widening trust gaps impede social integration and undermine the effective management of public health crises. However, little is known about how digital media use shaped trust gaps during a pandemic. OBJECTIVE: This study aims to investigate the relationships between digital media use, negative emotions, the family members-strangers trust gap, and the family members-acquaintances trust gap during the COVID-19 pandemic in China. We test the mediating role of negative emotions between digital media use and 2 trust gaps and compare the indirect effect of digital media use on 2 trust gaps through negative emotions. METHODS: A cross-sectional web-based survey was conducted in China between January 31, 2020, and February 9, 2020. A total of 1568 adults participated in the survey. Questions related to digital media use, negative emotions, trust in family members, trust in acquaintances, and trust in strangers during the pandemic were asked. Regression analyses were performed to test the associations between the examined variables. We used a 95% bootstrap CI approach to estimate the mediation effects. RESULTS: Digital media use was positively associated with negative emotions (B=0.17, SE 0.03; P<.001), which in turn were positively associated with the family members-strangers trust gap (B=0.15, SE 0.03; P<.001). Likewise, digital media use was positively associated with negative emotions (B=0.17, SE 0.03; P<.001), while negative emotions were positively associated with the family members-acquaintances trust gap (B=0.08, SE 0.03; P=.01). Moreover, the indirect effect of digital media use on the family members-strangers trust gap (B=0.03, SE 0.01; 95% CI 0.01-0.04) was stronger than that on the family members-acquaintances trust gap (B=0.01, SE 0.01; 95% CI 0.003-0.027). CONCLUSIONS: The results demonstrate that negative emotions resulting from the frequent use of digital media are a key factor that accounts for the widening trust gaps. Considering the increasing reliance on digital media, the findings indicate that the appropriate use of digital media can prevent the overamplification of negative emotions and curb the enlargement of trust gaps. This may help restore social trust and prepare for future public health crises in the postpandemic era.

Differential effects of digital media platforms on climate change risk information-sharing intention: A moderated mediation model.

This study analyzes the mechanisms through which risk messages about climate change lead to people's risk information-sharing intention, and how digital media platform type serves as a context that moderates those mechanisms. Our analysis is informed by the influence of presumed influence (IPI) model, and we adapt and expand that model in three ways. First, we apply the concept of perceived media reach to the context of digital media platforms, specifically news aggregators and social networking sites. Second, we integrate the two mediators of risk perception and presumed influence. Third, we examine potential moderating roles of digital media platforms in the IPI model. An online survey was conducted among 1000 South Korean adults, and a moderated mediation model (PROCESS Macro Model 59) generated the following results. (1) Perceived media reach was positively related to both mediators-risk perception and presumed influence. (2) By way of those two mediators, perceived reach significantly led to information-sharing intention. (3) Presumed influence, but not risk perception, was significantly related to information-sharing intention. (4) Digital media platforms moderated the relation between perceived reach and risk perception: the role of content-related risk perception was more pronounced in news aggregators, while the role of context-related presumed influence was greater in social networking sites. Theoretical and practical implications for risk communication are discussed.

The relationship between video games and social-emotional delay in Chinese rural preschoolers: A comparison of five types of media video games and social-emotional delay.

BACKGROUND: Recent studies have revealed a negative relationship between children's digital media use and social-emotional development. However, few studies distinguish between different digital devices and the different functions they provide that may lead to different outcomes. METHODS: This study explored the relationship between young children's time spent on various digital devices and their social-emotional delay based on a survey of 1182 preschoolers (3 to 6 years old) in rural China. Children's social-emotional delay was assessed through a validated screening tool (ASQ-SE II). RESULTS: Children's time spent on television, computers, tablets, or smartphones was not associated with their social-emotional delay. However, their risk of social-emotional delay increased as their time spent on game consoles increased. This relationship was reflected in five of the seven behavioural areas of children's social-emotional development (i.e., self-regulation, compliance, affect, social communications, and interactions with people). Moreover, it did not vary between children with different socioeconomic statuses. CONCLUSIONS: This study suggests a possible relationship between children's social-emotional delay and video games, which might need to be paid more attention to than other media types.

Digital Media-related Problems Contributing to Psychiatric Hospitalizations Among Children and Adolescents Before and After the Onset of the COVID-19 Pandemic.

The role of digital media in crises leading to youth psychiatric admissions is understudied and digital media use increased during the COVID-19 pandemic. In this cross-sectional study, demographics, clinical characteristics, and digital media-related problems (DMRPs; sub-coded as cyberbullying, online communication problems, triggering content, and limit-setting problems) were extracted from hospital records of youth (n = 1,101) admitted to a pediatric psychiatric unit from May 2018 to November 2021. DMRPs were identified in 127 admissions (11.5%), led by the online communication problems and limit-setting subtypes (both 4-5%). Significantly more overall problems were identified following the pandemic onset (13.9% of admissions vs. 9.1% before, p < 0.05). The limit-setting subtype specifically increased post-COVID-19 (6.0% vs. 2.7%, p < 0.01), and was associated with prior admissions, suicide attempts, and impulse control/behavioral disorders. Online communication problems were significantly more common among girls and youth with a history of trauma. Interventions in acute settings to mitigate consequences of DMRPs are needed.

How to drive heavily polluting companies to fulfill environmental responsibility? The synergy between environmental regulation and digital media coverage.

This paper addresses the question of how environmental regulation and digital media coverage, as formal and informal external monitoring mechanisms, affect corporate environmental responsibility fulfillment. Using the data of Shanghai and Shenzhen A-share listed companies in China's heavily polluting industries, this study showed that both environmental regulation and digital media coverage significantly improve responsive and strategic environmental responsibility fulfillment. After distinguishing the media tone, it was found that positive digital media coverage promotes the fulfillment of both responsive and strategic environmental responsibilities. In contrast, negative digital media coverage only stimulates the fulfillment of responsive environmental responsibility, which reflected an asymmetrical effect of media tone. Further, the hierarchy of governance amplifies the role of environmental regulation in triggering the fulfillment of responsive environmental responsibility but weakens its value to strategic environmental responsibility. Inconsistent with our predictions, the relationship between digital media coverage and corporate environmental responsibility fulfillment could not be significantly moderated by Confucian culture. In addition, environmental regulation and digital media coverage only existed in companies with separate chairperson and manager positions, which indicated that an excellent internal governance environment is a prerequisite for external monitoring mechanisms to play a role in environmental governance. This study enriches the literature on how to drive responsive and strategic environmental responsibility by uncovering an external governance effect of environmental regulation and digital media coverage on the fulfillment of corporate environmental responsibility, and provides inspiration for multiple environmental governance actors to promote the construction of ecological civilization collaboratively.

Social media literacy: A conceptual framework.

Concerns over the harmful effects of social media have directed public attention to media literacy as a potential remedy. Current conceptions of media literacy are frequently based on mass media, focusing on the analysis of common content and evaluation of the content using common values. This article initiates a new conceptual framework of social media literacy (SoMeLit). Moving away from the mass media-based assumptions of extant approaches, SoMeLit centers on the user's self in social media that is in dynamic causation with their choices of messages and networks. The foci of analysis in SoMeLit, therefore, are one's selections and values that influence and are influenced by the construction of one's reality on social media; and the evolving characteristics of social media platforms that set the boundaries of one's social media reality construction. Implications of the new components and dimensions of SoMeLit for future research, education, and action are discussed.
