Less Facebook use – More well-being and a healthier lifestyle? An experimental intervention study

Am I Happier Without You? Social Media Detox and Well-Being: A Meta-Analysis of Randomized Controlled Trials

With the penetration of social media into all aspects of people's lives, there is a growing trend of social media detox (taking a short break from social media). Although social media detox (SMD) has been theorized to influence well-being, vibrant research on this issue presents mixed results. This raises the question of whether SMD has positive or negative effects on well-being, calling for a synthesis of empirical evidence to determine if engaging in SMD can improve well-being. Systematic review and meta-analysis were conducted to synthesize evidence on the relationship between SMD and well-being from randomized controlled trials (RCTs). A total of 20 RCTs and 56 effect sizes (positive indicators of well-being k = 33; negative indicators of well-being k = 23) were analyzed. The meta-analysis findings using random effects showed that there was a positive and small effect of SMD on well-being, including positive indicators and negative indicators. The results of the moderating analysis showed that there was heterogeneity in the relationship between SMD and well-being caused by cultural background. Moreover, intervention duration moderated the relationship between SMD and negative indicators of well-being. This meta-analysis allows for an integration of conclusions from past studies and establishes a clearer understanding of the relationship between SMD and well-being.

Improving Well-Being Through Digital Detoxification Among Social Media Users: A Systematic Review and Meta-Analysis

Digital detoxification is a conscious disconnection from all smartphone activities for a certain period of time, which has been undertaken as effective by researchers to improve well-being, but studies found inconsistent results, with a primary focus on negative well-being, thus necessitating a need to focus on the positive aspect. As a result, the current study conducted a systematic review and meta-analysis to assess digital detoxification and its influence on users subjective and psychological well-being (PWB). A comprehensive search (up to November 19, 2023) across databases such as PubMed, Scopus, Web of Science, Pro-Quest, and Google Search yielded a total of 26 eligible studies (18 for meta-analysis) comprising 8,147 participants (Mage = 25.20 years). The Studies' quality was assessed using Cochrane's updated Risk of Bias Tool, and statistical analysis was performed in R Studio. Digital detoxification was found to be effective in improving subjective well-being (SWB) (Standardized mean difference [SMD] = 0.21, 95% CI: 0.06, 0.34; p < 0.01, I2 = 73.6%, n = 14 papers), as well as PWB (SMD = 0.27, 95% CI: 0.09, 0.46; p < 0.05; I2 = 0.0%, n = 4 papers). Notably, we detected no publication bias but addressed funnel plot asymmetry using Trim & Fill. Moderation analysis revealed the impact of internet coverage, developmental status, location, intervention effectiveness, and risk of bias on the estimated effect size for SWB. Meta-regression highlighted the significant influence of mean age, and although no potential outliers were identified, influential plots are provided for transparency. Our findings consolidate the efficacy of digital detoxification, emphasizing the need for nuanced consideration of study factors. This study contributes to the ongoing discourse on digital well-being, offering valuable insights for researchers, practitioners, and policymakers.

U.S. Adolescents' Daily Social Media Use and Well-being: Exploring the Role of Addiction-like Social Media Use

Associations between adolescent social media use and well-being are inconclusive, and studies using rigorous methodologies and objective measures are needed. Additionally, attention on what individual differences may moderate linkages between social media and well-being is necessary. We tested 1) how daily social media use (assessed via ecological momentary objective and self-reports) relates to daily subjective well-being, 2) the prevalence and concordance between scholar-defined addiction-like social media use (ASMU) and participant perceptions of social media addiction, 3) how these constructs relate to subjective well-being, and 4) if these constructs moderate daily links between social media use and subjective well-being. In a sample of 103 adolescents (M age=16.48, 47% female), ASMU and perceived addiction were highly correlated but some adolescents' classification differed when cross-referencing. Both were similarly associated with demographics and depressive symptoms. Self-reported, but not objectively-recorded, social media use was related to greater ASMU and perceived addiction. Links between social media use and well-being were inconsistent, with no moderation by ASMU or perceived addiction. Most adolescents endorsed some degree of ASMU, and future research should examine how social media-triggered disruptions to daily functioning relates to well-being.

Mobile App Intervention to Reduce Substance Use, Gambling, and Digital Media Use in Vocational School Students: Exploratory Analysis of the Intervention Arm of a Randomized Controlled Trial

BACKGROUND

During adolescence, substance use and digital media exposure usually peak and can become major health risks. Prevention activities are mainly implemented in the regular school setting, and youth outside this system are not reached. A mobile app ("Meine Zeit ohne") has been developed specifically for vocational students and encourages participants to voluntarily reduce or abstain from a self-chosen addictive behavior including the use of a substance, gambling, or a media-related habit such as gaming or social media use for 2 weeks. Results from a randomized study indicate a significant impact on health-promoting behavior change after using the app. This exploratory study focuses on the intervention arm of this study, focusing on acceptance and differential effectiveness.

OBJECTIVE

The aims of this study were (1) to examine the characteristics of participants who used the app, (2) to explore the effectiveness of the mobile intervention depending on how the app was used and depending on participants' characteristics, and (3) to study how variations in app use were related to participants' baseline characteristics.

METHODS

Log data from study participants in the intervention group were analyzed including the frequency of app use (in days), selection of a specific challenge, and personal relevance (ie, the user was above a predefined risk score for a certain addictive behavior) of challenge selection ("congruent use": eg, a smoker selected a challenge related to reducing or quitting smoking). Dichotomous outcomes (change vs no change) referred to past-month substance use, gambling, and media-related behaviors. The relationship between these variables was analyzed using binary, multilevel, mixed-effects logistic regression models.

RESULTS

The intervention group consisted of 2367 vocational students, and 1458 (61.6%; mean age 19.0, SD 3.5 years; 830/1458, 56.9% male) of them provided full data. Of these 1458 students, 894 (61.3%) started a challenge and could be included in the analysis (mean 18.7, SD 3.5 years; 363/894, 40.6% female). Of these 894 students, 466 (52.1%) were considered frequent app users with more than 4 days of active use over the 2-week period. The challenge area most often chosen in the analyzed sample was related to social media use (332/894, 37.1%). A total of 407 (45.5%) of the 894 students selected a challenge in a behavioral domain of personal relevance. The effects of app use on outcomes were higher when the area of individual challenge choice was equal to the area of behavior change, challenge choice was related to a behavior of personal relevance, and the individual risk of engaging in different addictive behaviors was high.

CONCLUSIONS

The domain-specific effectiveness of the program was confirmed with no spillover between behavioral domains. Effectiveness appeared to be dependent on app use and users' characteristics.

The "Vicious Circle of addictive Social Media Use and Mental Health" Model

Social media use (SMU) is a significant part of many people's everyday life. Research around the globe describes an increase of addictive SMU tendencies since the COVID-19 outbreak. The present work combines available findings in the "Vicious Circle of addictive Social Media Use and Mental Health" model to explain how social media (SM) activity can contribute to the development of addictive tendencies, which consequences they have for mental health, and how to prevent them. Following the model, the interplay between the risk factors negative experiences caused by daily hassles and by unexpected global and traumatic events, SMU (dimension "quality"), and SM flow can directly contribute to addictive SMU through the "vicious circle". Time spent on SMU (dimension "quantity"), symptoms of depression and anxiety, and the personality trait narcissism contribute to the circle as moderators. Symptoms of stress, insomnia, and suicide-related outcomes are described as potential consequences of addictive SMU. Based on longitudinal intervention studies, a conscious reduction of SMU time and an increase of physical activity, as well as positive mental health and mindfulness are identified as protective factors that reduce the risk of addictive tendencies. The model contributes to a better understanding of addictive SMU. Implications of the model for future research and praxis, specifically for mental health programs and therapeutic treatment are discussed.

Screen Media Use and Mental Health of Children and Adolescents: A Secondary Analysis of a Randomized Clinical Trial

Importance

Excessive screen media use has been associated with poorer mental health among children and adolescents in several observational studies. However, experimental evidence supporting this hypothesis is lacking.

Objective

To investigate the effects of a 2-week screen media reduction intervention on children's and adolescents' mental health.

Design, Setting, and Participants

This prespecified secondary analysis of a cluster randomized clinical trial with a 2-week follow-up included 89 families (with 181 children and adolescents) from 10 Danish municipalities in the region of Southern Denmark. All study procedures were carried out in the home of the participants. Enrollment began on June 6, 2019, and ended on March 30, 2021. This analysis was conducted between January 1 and November 30, 2023.

Intervention

Families were randomly allocated to a screen media reduction group or a control group. The 2-week screen media reduction intervention was designed to ensure a high level of compliance to the reduction in leisure-time screen media use. Participants allocated to the intervention group had to reduce their leisure-time screen media use to 3 hours per week or less per person and hand over smartphones and tablets.

Main Outcomes and Measures

The main outcome was the between-group mean difference in change in total behavioral difficulties, measured by the Strengths and Difficulties Questionnaire at 2-week follow-up. Results were estimated using mixed-effects tobit regression models. Analyses were carried out as both intention to treat and complete case.

Results

In the sample of 89 families including 181 children and adolescents (intervention group [45 families]: 86 children; mean [SD] age, 8.6 [2.7] years; 42 girls [49%]; control group [44 families]: 95 children; mean [SD] age, 9.5 [2.5] years; 57 girls [60%]), there was a statistically significant between-group mean difference in the total difficulties score, favoring the screen media reduction intervention (-1.67; 95% CI, -2.68 to -0.67; Cohen d, 0.53). The greatest improvements were observed for internalizing symptoms (emotional symptoms and peer problems; between-group mean difference, -1.03; 95% CI, -1.76 to -0.29) and prosocial behavior (between-group mean difference, 0.84; 95% CI, 0.39-1.30).

Conclusions and Relevance

This secondary analysis of a randomized clinical trial found that a short-term reduction in leisure-time screen media use within families positively affected psychological symptoms of children and adolescents, particularly by mitigating internalizing behavioral issues and enhancing prosocial behavior. More research is needed to confirm whether these effects are sustainable in the long term.

Prevalence and Associated Factors of Nomophobia Amongst the General Population in Makkah Province and Al-Madinah Province, Saudi Arabia: An Analytical Cross-Sectional Study

Background

Nomophobia is a public health issue that involves the fear of being without a mobile phone. The study aimed to estimate the prevalence of nomophobia and its relation to psychological factors, including depression and insomnia, among the general population in Makkah Province and Al-Madinah Province, Saudi Arabia.

Methods

This analytical cross-sectional study was conducted and data were obtained through a self-administered online questionnaire using the Patient Health Questionnaire-2 (PHQ-2) for depression, the Nomophobia Questionnaire (NMP-Q), and Insomnia Severity Index (ISI).

Results

A total of 1022 participants completed the questionnaire. The prevalence of nomophobia was 96.7%. Moderate nomophobia was prevalent (47.8%). Based on the PHQ-2, possible depression was identified in 47.3% of the respondents. 37.1% had sub-threshold insomnia. In terms of personal psychiatric history, the most common mental disorders in the participants included generalized anxiety disorder (9.9%) and major depressive disorder (9.7%). 61.6% of them used mobile devices for more than four hours per day.

Conclusion

Nomophobia is prevalent in the Makkah and Al-Madinah provinces in Saudi Arabia. The risk of nomophobia was significantly higher for participants who spent more hours using mobile devices, those with possible depression, and those having irritable bowel syndrome.

Which social media platforms matter and for whom? Examining moderators of links between adolescents' social media use and depressive symptoms

INTRODUCTION

Despite extensive research on social media and risks for mental health, not enough is known about individual differences in these risks.

METHODS

The present study, with data collected from 2018 to 2020, investigated the association between social media use (total and for specific platforms) and depressive symptoms in a sample of 237 American adolescents (Mage  = 15.10; SD = 0.49; 51.1% girls and 48.5% boys). We investigated several moderators: gender, self-esteem, personality, and negative reactions to social media. Covariates were gender, timing of the follow-up (pre vs. during the pandemic), and depressive symptoms a year earlier.

RESULTS

Results indicated that greater total time spent on social media was associated with higher levels of depressive symptoms. This effect held for Instagram, TikTok, and YouTube (but not Snapchat, Facebook, or Twitter). Several moderated effects were found. Twitter was associated with more depressive symptoms for girls but not boys. More frequent Instagram use was linked to more depressive symptoms for less or average-level extraverted teens but not for more extraverted teens, suggesting extraversion may be protective. More frequent TikTok use was associated with more depressive symptoms, particularly for teens who said they have more or average-level negative reactions to social media a year earlier.

CONCLUSIONS

This study suggests that certain adolescents may be at increased risk for serious mental health challenges, like elevated depressive symptoms, when using TikTok, Instagram, or Twitter more frequently, underscoring the importance of examining individual differences and particular social media platforms.

Restricting social networking site use for one week produces varied effects on mood but does not increase explicit or implicit desires to use SNSs: Findings from an ecological momentary assessment study

Recent research on the addictive potential of modern technologies such as the internet, smartphones, or social networking sites (SNSs) has suggested that emotional and motivational changes associated with the sudden discontinuation of engagement with the technology mirror the aversive consequences seen when drug use is ceased abruptly. This has been observed even in moderate users and interpreted as a manifestation of withdrawal, an important marker of physical dependence in substance use disorders. On the other hand, a growing literature emphasises the positive effects of "digital detox" on mental health and well-being. Using a battery of affective and motivational measures, both explicit and implicit, the present study tracked the effects of a week of significantly reduced SNS use in moderate to heavy SNS users (N = 51). Our pre-registered analyses showed that the intervention elicited affective changes neither consistent with a general withdrawal syndrome (i.e., increased negative affect and cravings) nor with a general beneficial effect on well-being: While our data indicated some abstinence-related decreases of negative affect and boredom, they also showed a reduction of positive affect. These changes occurred regardless of problematic/addictive use behaviours. Importantly, restricting SNS use for one week had no effect on implicit measures of SNS use motivation (i.e., approach biases, time distortion and effort expenditure for SNS access) nor did it influence explicit cravings and SNS cue-reactivity. Together our findings suggest that restricting SNS use has nuanced and potentially offsetting effects on well-being. These could arise because use reduction may concurrently remove experiences that trigger negative emotions (e.g., upward social comparisons or Fear of Missing Out) but also those that elicit positive emotions (e.g., social approval). The hypothesised lack of a net effect on well-being would be consistent with our finding that voluntary reduction of SNS use does not mitigate or exacerbate SNS-related urges.

The Impact of Social Comparisons More Related to Ability vs. More Related to Opinion on Well-Being: An Instagram Study

Social networks are gaining widespread popularity, with Instagram currently being the most intensively used network. On these platforms, users are continuously exposed to self-relevant information that fosters social comparisons. A distinction is made between ability-based and opinion-based comparison dimensions. To experimentally investigate the influence of these comparison dimensions on users' subjective well-being, an online exposure experiment (N = 409) was conducted. In a preliminary study (N = 107), valid exposure stimulus material was selected in advance. The results of the main study indicated that the exposure to ability-related social comparisons in the context of social media elicited lower well-being than exposure to opinion-related social comparisons. The theoretical and practical implications of this study consist of including the findings in clinical settings, e.g., affective disorder therapy, and the identification and reduction of ability-related content on social networking sites (SNSs). Future work should include assimilation and contrast effects which might interact with social comparison orientation and well-being.

Motivated and able: when is facebook used to seek friendship and social support?

When employing adaptive behaviors to a changing environment, ability and motivation work hand in hand. Our goal was to investigate how ability and motivation interact when utilizing Facebook for social support and friendship. We predicted that well-being and perceived social support would be negatively related to motivation to use Facebook for social support and friendship. We also predicted that computer-mediated communication (CMC) competence would positively related to these motives. A survey of 282 college students tested our mediational model. Results indicated that perceived social support mediated the relationship between well-being and motivations to use Facebook for social support, but only when CMC competence was high, meaning students experienced this relationship only when both motivated and able to use Facebook for the purpose of seeking social support. The results suggest that interventions to increase CMC competence through Facebook use can help students garner greater social support and improve overall well-being.

The Impact of Social Media Use Interventions on Mental Well-Being: Systematic Review

BACKGROUND

There is some evidence that more social media use is related to poorer mental well-being and that social media use can become problematic when it starts to interfere with a person's daily life and mental well-being. To address this issue and improve users' mental well-being, social media use interventions (eg, abstinence from social media) have been developed and evaluated. However, there is limited understanding of the effectiveness of these interventions in improving mental well-being.

OBJECTIVE

This systematic review aimed to synthesize the literature on the effectiveness of social media use interventions in improving mental well-being in adults.

METHODS

A systematic search (January 1, 2004, to July 31, 2022) was completed across 3 databases in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Experimental studies evaluating the impact of social media use interventions on mental well-being in adults were included. Outcomes related to mental well-being, such as depression, anxiety, stress, and loneliness, were included. A narrative synthesis without meta-analysis was completed to summarize the study characteristics and effectiveness by outcome and intervention type. The Effective Public Health Practice Project Quality Assessment Tool was used to measure the quality of the studies.

RESULTS

Of the 2785 studies identified through the systematic search, 23 (0.83%) were included in the analysis. Many of the included studies (9/23, 39%) found improvements in mental well-being, some (7/23, 30%) found mixed effects, and others (7/23, 30%) found no effect on mental well-being. Therapy-based interventions that used techniques such as cognitive behavioral therapy were more effective than limiting use of social media or full abstinence from social media, with 83% (5/6) of these studies showing improvements in mental well-being compared with 20% (1/5) and 25% (3/12), respectively. Depression was the most frequently investigated and improved outcome with 70% (7/10) of the studies showing a significant improvement in depression after the intervention, whereas other outcomes showed more varied results. Quality was poor, with 96% (22/23) of the studies receiving a weak global score, mostly for issues related to selection bias because most of the studies (16/23, 70%) used a convenience sampling of university students.

CONCLUSIONS

This review provides some evidence that social media use interventions are effective in improving mental well-being, especially for depression and when using therapy-based interventions. Further experimental and longitudinal research is needed with representative samples to investigate who may benefit most from social media use interventions. This will help to develop guidance and recommendations for policy makers and clinicians on how best to manage problematic social media use.

Negative psychological and physiological effects of social networking site use: The example of Facebook

Social networking sites (SNS), with Facebook as a prominent example, have become an integral part of our daily lives and more than four billion people worldwide use SNS. However, the (over-)use of SNS also poses both psychological and physiological risks. In the present article, we review the scientific literature on the risk of Facebook (over-)use. Addressing this topic is critical because evidence indicates the development of problematic Facebook use ("Facebook addiction") due to excessive and uncontrolled use behavior with various psychological and physiological effects. We conducted a review to examine the scope, range, and nature of prior empirical research on the negative psychological and physiological effects of Facebook use. Our literature search process revealed a total of 232 papers showing that Facebook use is associated with eight major psychological effects (perceived anxiety, perceived depression, perceived loneliness, perceived eating disorders, perceived self-esteem, perceived life satisfaction, perceived insomnia, and perceived stress) and three physiological effects (physiological stress, human brain alteration, and affective experience state). The review also describes how Facebook use is associated with these effects and provides additional details on the reviewed literature, including research design, sample, age, and measures. Please note that the term "Facebook use" represents an umbrella term in the present work, and in the respective sections it will be made clear what kind of Facebook use is associated with a myriad of investigated psychological variables. Overall, findings indicate that certain kinds of Facebook use may come along with significant risks, both psychologically and physiologically. Based on our review, we also identify potential avenues for future research.

Engaging in physical activity instead of (over)using the smartphone: An experimental investigation of lifestyle interventions to prevent problematic smartphone use and to promote mental health

Aim

Tendencies of problematic smartphone use (PSU) have risen during the past decade. As PSU is consistently linked to mental health issues, measures to prevent its appearance and to promote mental health are urgently required.

Subject and Methods

The present study investigated the impact of three interventions on health behavior, PSU, positive mental health (PMH), and depression and anxiety symptoms. Overall, 503 persons from Germany (M age = 29.19, SD age = 10.51, range: 18-79) participated in the study. Over 14 days, the three experimental groups (a) reduced their daily smartphone use time by 60 minutes, (b) increased their daily level of physical activity by 30 minutes, and (c) combined both measures. The control group continued its behavior as usual. Outcomes were assessed via online surveys at five measurement time points (baseline, intermediate, post-intervention, and 1 and 3 months after the intervention).

Results

All interventions resulted in a significant increase in weekly physical activity and in reduced symptoms of PSU, depression, and anxiety. Furthermore, the smartphone reduction and the combination of both measures contributed to a significant reduction of participants' daily smartphone use and higher levels of PMH. The effects of the reduction of smartphone use time and its combination with increased physical activity were more stable in the longer term than the increase in physical activity only.

Conclusion

Combined with an increase in physical activity, the reduction of smartphone use time could serve as an efficient and cost-effective measure for the prevention of PSU and the promotion of mental health.

Effects of an App-Based Intervention Program to Reduce Substance Use, Gambling, and Digital Media Use in Adolescents and Young Adults: A Multicenter, Cluster-Randomized Controlled Trial in Vocational Schools in Germany

Vocational students are a risk group for problematic substance use and addictive behaviors. The study aim was to evaluate the effects of an app-based intervention on tobacco, e-cigarettes, alcohol, and cannabis use as well as gambling and digital media-related behaviors in the vocational school setting. A total of 277 classes with 4591 students (mean age 19.2 years) were consecutively recruited and randomized into an intervention (IG) or waitlist control group (CG). Students from IG classes received access to an app, which encouraged a voluntary commitment to reduce or completely abstain from the use of a specific substance, gambling, or media-related habit for 2 weeks. Substance use, gambling, and digital media use were assessed before and after the intervention in both groups with a mean of 7.7 weeks between assessments. Multi-level logistic regression models were used to test group differences. Intention-to-treat-results indicated that students from IG classes had a significantly larger improvement on a general adverse health behavior measure compared to CG (OR = 1.24, p = 0.010). This difference was mainly due to a significantly higher reduction of students' social media use in the IG (OR = 1.31, p < 0.001). Results indicate that the app "Meine Zeit ohne" is feasible for the target group and seems to have a small but measurable impact on students' health behavior.

Temporal associations between physical activity and three types of problematic use of the internet: A six-month longitudinal study

BACKGROUND AND AIMS

Internet use has become an important part of daily living. However, for a minority it may become problematic. Moreover, problematic use of the Internet/smartphone (PUIS) has been associated with low physical activity. The present study investigated the temporal associations between three types of PUIS (i.e., problematic smartphone use [PSPU], problematic social media use [PSMU] and problematic gaming [PG]) and physical activity among Taiwanese university students.

METHODS

A six-month longitudinal survey study comprising three time points for assessments was conducted. From the original 974 participants, a total of 452 completed all three waves of an online survey comprising the International Physical Activity Questionnaire Short Form (IPAQ-SF) assessing physical activity level, Smartphone Application-Based Addiction Scale (SABAS) assessing PSPU, Bergen Social Media Addiction Scale (BSMAS) assessing PSMU, and Internet Gaming Disorder Short Form (IGDS9-SF) assessing PG.

RESULTS

The linear mixed effects model found positive temporal associations of PSMU and PG with physical activity level (PSMU: B = 85.88, SE = 26.24; P = 0.001; PG: B = 36.81, SE = 15.17; P = 0.02). PSPU was not associated with physical activity level (B = 40.54, SE = 22.99; P = 0.08). Additionally, the prevalence rates were 44.4% for at-risk/PSPU, 24.6% for at-risk/PSMU, and 12.3% for at-risk/PG.

DISCUSSION AND CONCLUSIONS

PSMU and PG unexpectedly demonstrated correlations with higher physical activity level. The nature of these relationships warrants additional investigation into the underlying mechanisms in order to promote healthy lifestyles among university students.

Positive mental health and mindfulness as protective factors against addictive social media use during the COVID-19 outbreak

The outbreak of COVID-19 caused high psychological burden for many people. Some people tend to excessive social media use (SMU) to escape the negative emotions which can foster addictive tendencies. The present study investigated positive mental health (PMH) and mindfulness as protective factors that could reduce the risk for addictive SMU. Data of 1,049 participants from Germany were assessed via online surveys in autumn 2021. The current results reveal a positive relationship between COVID-19 burden and addictive SMU. Both were negatively linked to PMH and mindfulness. In a moderated mediation analysis, the relationship between COVID-19 burden and addictive SMU was mediated by PMH. Mindfulness moderated the association between PMH and addictive SMU. The COVID-19 situation can be burdensome and contribute to dysfunctional coping strategies such as addictive SMU. However, PMH and mindfulness serve as protective factors. The protective effect of mindfulness could be especially important for persons with low PMH.

Facebook use intensity and depressive symptoms: a moderated mediation model of problematic Facebook use, age, neuroticism, and extraversion

BACKGROUND

Research on the relationship between Facebook use intensity and depressive symptoms has resulted in mixed findings. In contrast, problematic Facebook use has been found to be a robust predictor of depressive symptoms. This suggests that when intense Facebook use results in a problematic usage pattern, it may indirectly predict depressive symptoms. However, this mediation pathway has never been examined. Moreover, it remains unclear whether the possible indirect relationship between Facebook use intensity and depressive symptoms through problematic Facebook use is moderated by demographic (age), and personality (neuroticism and extraversion) characteristics.

METHODS

To address these gaps, we conducted an online cross-sectional study (n = 210, 55% female, age range: 18-70 years old, M_age = 30.26, SD = 12.25). We measured Facebook use intensity (Facebook Intensity Scale), problematic Facebook use (Bergen Facebook Addiction Scale), depressive symptoms (Center for Epidemiologic Studies Depression Scale Revised), and neuroticism and extraversion (Ten Item Personality Inventory).

RESULTS

A mediation analysis revealed that problematic Facebook use fully mediates the relationship between Facebook use intensity and depressive symptoms. Moreover, a moderated mediation analysis demonstrated that this indirect relationship is especially strong among young users and users scoring high on neuroticism.

CONCLUSIONS

These findings expand our understanding of the mechanisms underlying the relationship between Facebook use intensity and depressive symptoms and describe user characteristics that act as vulnerability factors in this relationship.

A qualitative study on negative experiences of social media use and harm reduction strategies among youths in a multi-ethnic Asian society

PURPOSE

This study aimed to expand and inform the emerging body of research on the negative experiences of social media use among youths and how youths deal with them, in an Asian setting, using a qualitative approach.

METHODS

Data were collected using 11 focus group discussions (FGDs) and 25 semi-structured interviews (SIs) among youths aged 15 to 24 years residing in Singapore who were recruited via purposive sampling. Data were analysed using thematic analysis.

RESULTS

The salient negative effects mentioned by participants include the development of negative reactions and feelings from upward comparisons with others (e.g., others' achievements and lifestyle), receiving hurtful comments, exposure to controversial content (e.g., political events and social movements), as well as the perpetuation of negative feelings, behaviours, and sentiments (e.g., rumination, unhealthy eating behaviour, and self-harm). Participants also described strategies which they have employed or deemed to be useful in mitigating the negative effects of social media use. These include filtering content and users, taking breaks from social media, cognitive reframing, and self-affirmation, where they identify and change stress-inducing patterns of thinking by setting realistic social, physical, and lifestyle expectations for themselves, and focusing on self-development.

CONCLUSION

The current results highlight that while youths experience negative effects of social media use, they have high media literacy and have employed strategies that appear to mitigate the negative effects of social media use. The findings can inform various stakeholders involved in helping youths navigate the harms of social media use or provide directions for intervention studies aimed at reducing the harms of social media use.

A three-wave panel study on longitudinal relations between problematic social media use and psychological distress during the COVID-19 pandemic

BACKGROUND

It still remains unclear whether problematic social media use (PSMU) is a cause or a consequence of psychological distress. The present study aimed to investigate the temporal relationships between PSMU and psychological distress through a three-wave panel study (between April and July 2020, with an interval of 1 month between each period of time).

METHODS

3,912 adult Italian participants were surveyed during the COVID-19 pandemic for psychological distress (Depression, Anxiety and Stress Scale) and PSMU (Bergen Social Media Addiction Scale). Random-Intercept Cross-Lagged Panel Models were applied to disaggregate between-person from within-person associations as regards PSMU and an individual's distress.

RESULTS

On a between-person level we found that adults with higher PSMU also reported heightened levels of psychological distress across the three waves. However, on a within-person level, no cross-lagged associations were found between changes in distress and subsequent changes in PSMU and vice versa. The results were largely unchanged with the inclusion of participants' gender and age or COVID-19-related fears as covariates, and when the three subscales of depression, anxiety and stress were examined in separate models.

CONCLUSIONS

The current study suggests that the link between PSMU and psychological distress is mainly driven by trait-like differences and not by state-like individual changes over time.

Self-esteem only goes so far: the moderating effect of social media screen time on self-esteem and depressive symptoms

This study assessed the independent association of self-esteem and social media screen time on depressive symptoms, as well as the moderating role of social media screen time in the relationship between self-esteem and depressive symptoms. The Mobile Screen Time Project was a cross-sectional, web-based survey conducted from March to May of 2019. 437 U.S. college students were recruited via social networks from two institutions of higher education. Multivariable logistic regression assessed the associations between self-esteem and average daily social media time with depressive symptoms; an interaction effect was explored. Self-esteem had an inverse association (AOR = 0.87, 95% CI: 0.80-0.94) and daily social media time had a significant association with depressive symptoms (AOR = 1.11, 95% CI: 1.02-1.22) after adjusting for sexual and gender status, race/ethnicity, age, social status, and insomnia. We found a significant moderating effect (p = 0.016) of daily social media time. The more time spent on social media, the less protective self-esteem was against depressive symptoms. Those suffering from depressive symptoms or low self-esteem may benefit from reducing their social media use, intentionally exposing themselves to positive content and leveraging peer-to-peer social support through social media to create a sense of belonging.

Effects of limiting digital screen use on well-being, mood, and biomarkers of stress in adults

Studies have linked higher digital screen use with poorer mental health. However, there is limited experimental evidence to suggest a causal relationship. In this trial, we aimed to investigate the effects of limiting recreational digital screen use on mental well-being, mood, and biomarkers of stress in healthy young and middle-aged adults. We randomly allocated 89 families (including 164 adults) to participate in an extensive screen media reduction intervention or control. Participants in the intervention group were instructed to decrease their recreational screen use to less than 3 hours/week/person. Intervention compliance was assessed using applications and tv-monitors. Overall subjective mental well-being and mood, and collected daily biomarkers of stress (salivary cortisol and cortisone) was assessed at baseline and 2-week follow-up. Reducing recreational digital screen use resulted in significantly improved self-reported well-being and mood in adults allocated to the intervention compared to control. We observed no intervention effects for biomarkers of stress. (ClinicalTrials.gov: NCT04098913, 23/09/2019).

Implicit Cognitions, Use Expectancies and Gratification in Social-Networks-Use Disorder and Tobacco Use Disorder

Abstract: Aims: The problematic use of social networks is discussed as a further specific type of Internet-use disorders. Our project aims to clarify whether social-networks-use disorder (SNUD) is marked by characteristics of addictive behaviors by tracking behavior and investigating the relevance of 1) implicit cognitions, 2) the experiences of gratification and compensation and 3) use expectancies in SNUD compared to tobacco-use disorder. Methodology: Four groups will be examined: individuals with 1) SNUD without tobacco use, 2) risky use patterns with regard to social networks without tobacco use, 3) tobacco use disorder and 4) healthy controls. All participants first complete a laboratory examination including the Implicit Association Test (IAT) and the Approach-Avoidance task (AAT). We will use smartphone-based data tracking for 14 days following laboratory testing to record smoking and social-networks-use patterns. During this period, we further measure use expectancies and the experience of gratification and compensation by means of a smartphone-based experience sampling method (ESM). Conclusions: This is the first study to examine relevant characteristics of addictive behaviors in individuals with SNUD compared to individuals with tobacco use, using a combination of experimental psychological methods and smartphone-based measurements. We expect that this investigative approach will contribute to a deeper understanding of the processes involved in SNUD.

Experimental longitudinal evidence for causal role of social media use and physical activity in COVID-19 burden and mental health

Aim

The COVID-19 outbreak has severely impacted people's mental health. The present experimental study investigated how to reduce this negative effect by a combination of two interventions.

Subject and methods

Participants (N total = 642) were users of social media in Germany. For two weeks, the social media group (N = 162) reduced its social media use (SMU) by 30 minutes daily, the physical activity group (N = 161) increased its physical activity by 30 minutes daily, the combination group (N = 159) followed both instructions, and the control group (N = 160) did not get specific instructions. Online surveys assessed variables of SMU, physical activity, mental health, COVID-19 burden, and lifestyle at six measurement time points up to six months after the intervention.

Results

In the experimental groups, (addictive) SMU, depression symptoms, and COVID-19 burden decreased, while physical activity, life satisfaction, and subjective happiness increased. All effects were stronger and more stable in the combination group in the longer-term. Smoking behavior decreased in the social media group only.

Conclusion

Thus, the conscious combination of less SMU and more physical activity leads causally to more psychological resilience against negative pandemic impacts and to higher levels of mental health over six months. Prevention programs could improve their effectiveness by integrating the time- and cost-efficient interventions - separately or in combination.

Factors associated with Facebook addiction among university students amid the COVID-19 pandemic: Findings from an online cross-sectional survey

Background

Facebook addiction (FA) has been suggested as a potential behavioral addiction. There is a severe lack of research evidence regarding the Facebook addiction behavior among university students during the ongoing COVID-19 pandemic. The aim of this study was to determine factors associated with Facebook addiction among Bangladeshi university students.

Methods

A cross-sectional online survey was conducted among 2,161 Bangladeshi university students during the COVID-19 pandemic from June 2021 to September 2021. A well fitted regression model in R programming language was used for this study.

Results

Female respondents and those whose family monthly income was <25,000 BDT were more addicted to Facebook than other respondents. Respondents who lost a family member or a relative to COVID-19, engaged in physical activities (exercise) during the pandemic, used Facebook for work purposes or used Facebook to relieve daily stress were more addicted to Facebook.

Conclusion

Overuse of social media is problematic as it can trigger several mental health symptoms, especially among students. Adequate and effective interventions are required to educate students about the dangers of Facebook addiction and to provide an alternative, healthy options.

Effects of restricting social media usage on wellbeing and performance: A randomized control trial among students

Recent research has shown that social media services create large consumer surplus. Despite their positive impact on economic welfare, concerns are raised about the negative association between social media usage and well-being or performance. However, causal empirical evidence is still scarce. To address this research gap, we conduct a randomized controlled trial among students in which we track participants' daily digital activities over the course of three quarters of an academic year. In the experiment, we randomly allocate half of the sample to a treatment condition in which social media usage (Facebook, Instagram, and Snapchat) is restricted to a maximum of 10 minutes per day. We find that participants in the treatment group substitute social media for instant messaging and do not decrease their total time spent on digital devices. Contrary to findings from previous correlational studies, we do not find any significant impact of social media usage as it was defined in our study on well-being and academic success. Our results also suggest that antitrust authorities should consider instant messaging and social media services as direct competitors before approving acquisitions.

Addictive social media use during Covid-19 outbreak: Validation of the Bergen Social Media Addiction Scale (BSMAS) and investigation of protective factors in nine countries

Since the Covid-19 outbreak, addictive social media use increased in many countries. To better understand this development, a universal instrument for the assessment of addictive social media use is required. Against this background, we examined the psychometric properties of the Bergen Social Media Addiction Scale (BSMAS) in representative population samples in nine countries (N = 9418, age range: "18 to 24 years" (youngest group), "55 years and older" (oldest group): China, France, Germany, Poland, Russia, Spain, Sweden, U.K., U.S.). Furthermore, we investigated potential factors and mechanisms that could be associated with addictive social media use. Our cross-national findings show that the BSMAS is a unidimensional reliable and valid instrument. Moreover, they reveal that the negative association between positive mental health and addictive social media use is mediated by sense of control in seven of the nine countries (exception: China, Russia). Thus, it can be hypothesized that activities which increase positive mental health could indirectly contribute to the decrease of addictive social media use. We identified conscious engagement in physical activity and a regular sleep rhythm during the pandemic as such potential activities. The fostering of both by governmental programs could enhance positive mental health and reduce addictive social media use.

The Relationship of Social Media Addiction With Internet Use and Perceived Health: The Moderating Effects of Regular Exercise Intervention

The popularity of online social media in recent years has not only brought information and social convenience to people's lives, but has also given rise to many problems, among which social media addiction (SMA) has become a concern of many scholars and experts. Past research has shown that regular exercise (REx) can have many health benefits for the body, so numerous scholars and experts believe that this may be one possible strategy for reducing the health effects of online community addiction and Internet use (IU). Therefore, this study adopted a secondary data research approach to explore and predict the effect of age on social media use and personal health, and therefore included age as a control variable to investigate whether the intervention of REx, excluding the effect of age, moderates the effect of SMA on IU and on perceived health (PH). The participants of this study were adults aged 18 years or older in Taiwan, using the 2019 "Survey Research Data Archive," Vol. 7, No. 5 data. A total of 1,933 questionnaires were retrieved, and after elimination of invalid responses, 1,163 data were analyzed using Partial Least Squares Structural Equation Modeling, PLS-SEM. The results were as follows: (1) SMA positively affected IU, (2) SMA could negatively affect PH, (3) there was no statistical effect of IU on PH, (4) SMA did not indirectly affect PH through IU, (5) REx had a moderating effect on SMA and IU, and (6) REx did not regulate the effect of SMA on PH. First, from these results, it is clear that the negative health effects of SMA may not be simply due to prolonged IU. Secondly, while it is true that the moderating effect for people with low levels of SMA can reduce IU, for people with high levels of SMA, the moderating effect of REx becomes a catalyst for increased Internet usage behavior. Finally, we draw conclusions based on the results of the study and propose directions and recommendations for follow-up research.

Effectiveness of an app-based intervention to reduce substance use, gambling, and digital media use in vocational school students: study protocol for a randomized controlled trial

BACKGROUND

Substance-related and addictive disorders are among the most common mental disorders in adolescence and young adulthood. Vocational school students are a risk group for problematic substance use and addictive behavior. However, the availability of evidence-based prevention concepts and programs is underdeveloped in the vocational school setting.

METHODS/DESIGN

A two-arm cluster randomized waitlist-controlled trial will be conducted to evaluate the effectiveness of an app-based intervention to decrease substance use, gambling, and digital media use in vocational school students in Germany. Vocational students will participate in an app-based intervention that is designed to support voluntary commitment to abstain from or reduce substance or digital media use over a period of 2 weeks. The "education-as-usual" control arm will have access to the intervention after data collection is completed. One of the primary outcome measures will be the use of alcohol, nicotine, and digital media 30 days after the intervention. Several secondary outcome measures will also be included, such as cannabis consumption, gambling, symptoms of stress, physical activity, mindfulness, well-being, impulsivity and sensation seeking, and readiness to change. A total of 4500 vocational students from 225 classes will be recruited and randomized across three German federal states.

DISCUSSION

This study protocol describes the design of an RCT testing the effectiveness of an app-based intervention to reduce addictive behaviors in vocational school students. It is expected that this approach will be feasible for and effective in the vocational school setting and that the study provides comprehensive information on the key factors involved in temporary abstaining or reducing substance or digital media use.

Relationship between sense of control, psychological burden, sources of information and adherence to anti-COVID-19 rules

BACKGROUND

Adherence to anti-COVID-19 rules is important to slow down the pandemic spread. The present study investigated potential predictors of the adherence.

METHODS

Data of 1.247 participants from Germany (age: M (SD) = 22.99 (6.18)) were assessed via online surveys in autumn and winter 2020. The focus of the data collection was on adherence to anti-COVID-19 rules, sense of control, psychological burden, and sources of COVID-19 information.

RESULTS

In moderated mediation analyses, the positive relationship between sense of control and adherence to anti-COVID-19 rules was significantly mediated by the level of psychological burden experienced by the COVID-19 situation. The source of COVID-19 information significantly moderated the negative association between burden and adherence. Specifically, the higher the use of social media (e.g., Facebook, Twitter) and the lower the use of official governmental sites and of television reports, the closer the link between high burden and low adherence.

LIMITATIONS

Due to the cross-sectional study design, the present findings allow only hypothetical assumptions of causality.

CONCLUSIONS

The present results disclose potential mechanisms that could contribute to the adherence to anti-COVID-19 rules. They emphasize the role of the COVID-19 information source for the adherence level. Potential ways of how the level of adherence could be enhanced are discussed.

Can physical activity foster mental health by preventing addictive social media use? – A longitudinal investigation during the COVID-19 pandemic in Germany

Introduction

The COVID-19 pandemic contributed to an increase of mental health problems like depression, anxiety, stress symptoms, and Internet-based addictive behaviors. Therefore, the present longitudinal study investigated whether physical activity might prevent addictive social media use (SMU) and thus foster positive mental health (PMH) and decrease negative mental health (NMH).

Methods

Data were assessed in a sample of 356 participants (Mage = 27.43, SDage = 6.59) from Germany via online surveys at two measurement time points in spring 2020 (baseline, BL) and one year later in spring 2021 (follow-up, FU). Moderated mediation analyses were conducted for the investigation of the relations.

Results

Analyses revealed that addictive SMU (BL) mediated the relationship between physical activity (BL) and PMH (FU) as well as symptoms of depression, anxiety, and stress (FU). Moreover, the association between physical activity and addictive SMU was moderated by the level of burden caused by COVID-19 (BL), i.e., it was significant for medium and high, but not for low burden.

Limitations

The mostly female and relatively young sample limit the generalizability of the current findings. Moreover, the relationships should be investigated in further countries to different time points.

Conclusions

The findings indicate positive effects of physical activity on PMH and NMH by the reduction of tendencies of addictive SMU. Especially people who experience high levels of burden by COVID-19 may benefit from regular physical activity. This could be a cost-effective, low-threshold prevention strategy for meeting the pandemic induced challenges for mental health.

Does a 7-day restriction on the use of social media improve cognitive functioning and emotional well-being? Results from a randomized controlled trial

Introduction

Screen time apps that allow smartphone users to manage their screen time are assumed to combat negative effects of smartphone use. This study explores whether a social media restriction, implemented via screen time apps, has a positive effect on emotional well-being and sustained attention performance.

Methods

A randomized controlled trial (N = 76) was performed, exploring whether a week-long 50% reduction in time spent on mobile Facebook, Instagram, Snapchat and YouTube is beneficial to attentional performance and well-being as compared to a 10% reduction.

Results

Unexpectedly, several participants in the control group pro-actively reduced their screen time significantly beyond the intended 10%, dismantling our intended screen time manipulation. Hence, we analyzed both the effect of the original manipulation (i.e. treatment-as-intended), and the effect of participants' relative reduction in screen time irrespective of their condition (i.e. treatment-as-is). Neither analyses revealed an effect on the outcome measures. We also found no support for a moderating role of self-control, impulsivity or Fear of Missing Out. Interestingly, across all participants behavioral performance on sustained attention tasks remained stable over time, while perceived attentional performance improved. Participants also self-reported a decrease in negative emotions, but no increase in positive emotions.

Conclusion

We discuss the implications of our findings in light of recent debates about the impact of screen time and formulate suggestions for future research based on important limitations of the current study, revolving among others around appropriate control groups as well as the combined use of both subjective and objective (i.e., behavioral) measures.

Factors affecting individual online rumor sharing behavior in the COVID-19 pandemic

With the outbreak of COVID-19, online sharing of rumors about the disease is of growing concern worldwide. Drawing on the stimulus-organism-response (S-O-R) framework, this study aims to explore the impacts of peer condition and peer communication on fear of COVID-19, and the impact of fear of COVID-19 on online rumor sharing behavior, by considering the contingency effect of health self-efficacy. Data from 1167 respondents to an online survey in China were adopted to test our research model. The results indicate that peer communication and peer condition induce fear of COVID-19, and fear of COVID-19 results in online rumor sharing. Fear of COVID-19 mediates the effects of peer communication and peer condition on online rumor sharing. Health self-efficacy alleviates the positive effect of peer communication on fear of COVID-19, and the positive effect of fear of COVID-19 on online rumor sharing. This study advances the literature on online rumor sharing and S-O-R, and provides practical implications to social media users and governments.

It's all about control: Sense of control mediates the relationship between physical activity and mental health during the COVID-19 pandemic in Germany

COVID-19-related burden has a significant impact on mental health and has led to an increase of depression, anxiety, and stress symptoms. Physical activity has been suggested to mitigate the negative effects of the pandemic and to foster mental health. The present study aimed to investigate, whether sense of control might mediate the supposed beneficial effects of physical activity on positive (PMH) and negative mental health (NMH) in unpredictable extraordinary situations. Data were assessed in a sample of 568 students (M _age = 19.90, SD _age = 4.52) from Germany via an online survey in fall 2020. Mediation analyses revealed that sense of control mediated the relation between physical activity and PMH as well as depression, anxiety, and stress symptoms, respectively. The findings indicate that physical activity may be a promising strategy for fostering sense of control and thus mental health. Due to its practical implications and practicability, engagement in physical activity could be an effective way to reduce the NMH consequences of the current COVID-19 situation, and therefore should be addressed in actions for long-term prevention and intervention.

Social Media as Source of Information, Stress Symptoms, and Burden Caused by Coronavirus (COVID-19)

Abstract. This cross-national study investigated the extent of social media use (SMU) as a source of information about COVID-19, and its relationship with the experienced burden caused by the pandemic. Representative data from eight countries (France, Germany, Poland, Russia, Spain, Sweden, the UK, the USA) were collected online (end of May to the beginning of June 2020). Of the overall 8,302 participants, 48.1% frequently used social media (SM) as a COVID-19 information source (range: 31.8% in Germany, to 65.4% in Poland). In the overall samples and in all country-specific samples, regression analyses revealed the experienced burden caused by COVID-19 to be positively associated with SMU and stress symptoms. Furthermore, stress symptoms partly mediated the relationship between SMU and the burden. The results emphasize the significant association between the use of SM as a source of information, individual emotional state, and behavior during the pandemic, as well as the significance of conscious and accurate use of SM specifically during the COVID-19 outbreak.

Social Media Use and Vulnerable Narcissism: The Differential Roles of Oversensitivity and Egocentricity

Narcissism is a multi-dimensional personality trait characterised by grandiosity, vanity, low empathy, and a desire for admiration. Previous research has suggested that social media sites are ideal platforms for people with narcissistic traits to satisfy a desire for attention. However, less is understood about the relationship between social media and vulnerable narcissism, characterised by vulnerability, insecurity, and oversensitivity. A total of 115 participants completed the Hypersensitive Narcissism Scale (HSNS) and questions relating to social media use. Exploratory and confirmatory factor analysis supported a two-factor model of vulnerable narcissism; oversensitivity and egocentrism. Results showed that greater oversensitivity was significantly associated with greater scores in all six aspects of social media use. Specifically, time spent on social media, frequency of posts, concerns about numbers of likes and comments, being overly sensitive about negative remarks, feelings of jealousy, and a greater difference in how they portray themselves on social media compared to real life. Egocentricity was significantly associated with less concern over negative remarks and a greater difference in how they portray themselves on social media compared to real life. These results suggest that vulnerable narcissism is not a unitary trait and that subfactors oversensitivity and egocentricity contribute differentially to aspects of social media use.

Facebook Addiction Partially Mediated the Association Between Stress Symptoms and Sleep Disturbance Among Facebook Users

Stress symptoms, Facebook addiction, and sleep disturbances have important effects on the health of every individual. However, very few studies have examined the association between stress symptoms, Facebook addiction, and sleep disturbances. This study investigated the mediating effect of Facebook addiction on the association between stress symptoms and sleep disturbances among Facebook users in Vietnam. Three hundred fifty-four Facebook users in Vietnam have completed measures to assess symptoms of stress, levels of Facebook addiction, and sleep disturbances. In the sample, stress was positively associated with sleep disturbances and Facebook addiction partially mediated the association between stress and sleep disturbance (stress was positively associated with Facebook addiction and Facebook addiction was positively associated with sleep disturbances). Thus, our findings demonstrate that stressful individuals tend to be addicted to Facebook, which increase the risk of sleep disturbances. Therefore, interventions aimed at improving sleep quality for Facebook users should focus on reducing stress and reducing dependence on Facebook.

Moderated-mediation analysis of problematic social networking use: The role of anxious attachment orientation, fear of missing out and satisfaction with life

Anxious attachment orientation has a well document relationship with problematic social networking use. Additionally, the fear of missing out and satisfaction with life have emerged as robust predictors of problematic social networking use. However, it remains unclear how these determinants may converge to promote problematic social networking use. Thus, the current study examined how anxious attachment, fear of missing out, and satisfaction with life concurrently influence problematic social networking use. One hundred and eighty-eight participants were recruited from online dissertation swap sites to complete an online questionnaire. The mean age of the sample was 31.95 (SD = 11.54) and 67% were female. As expected, anxious attachment was positively related to problematic social networking use. Further analysis indicated the relationship between anxious attachment and problematic social networking use was mediated by fear of missing out, and this relationship was moderated by satisfaction with life. These findings indicate that engendering greater levels of life satisfaction in those who engage in problematic social networking could present a viable prevention or treatment strategy.

Coronavirus (COVID-19) outbreak: Addictive social media use, depression, anxiety and stress in quarantine - an exploratory study in Germany and Lithuania

Background

To slow down the spread of the COVID-19 pandemic, governments of many countries introduced various behavioral measures starting March 2020. The measures included domestic quarantine (not leaving home) for infected or potentially infected people. Due to the need for social distancing, online activity increased in spring 2020. This could foster the risk for addictive social media use (SMU). The present study investigated tendencies of addictive SMU and their relationship with depression, anxiety and stress symptoms specifically among individuals who stayed in domestic quarantine due to COVID-19 in Germany and Lithuania.

Methods

In Germany (N = 529; quarantine group: n = 157, non-quarantine group: n = 372) and in Lithuania (N = 325; quarantine group: n = 54, non-quarantine group: n = 271), data were assessed via online surveys in spring 2020.

Results

In both countries, persons in quarantine had higher levels of addictive SMU, depression, anxiety and stress symptoms than individuals who were not in quarantine. The difference was significant only for addictive SMU in the German sample. The significant positive correlations between addictive SMU and symptoms of depression, anxiety and stress were stronger in both quarantine groups than in the non-quarantine groups.

Limitations

The mostly female, young and well-educated composition of both investigated samples limits generalizability of the current findings.

Conclusions

Results reveal first evidence that the use of social media during domestic COVID-19 quarantine might contribute to the increase of addictive tendencies and negatively impact well-being. Alternative ways of daily routine during the quarantine are discussed.

Cognitive Behavioral Therapy-Based Short-Term Abstinence Intervention for Problematic Social Media Use: Improved Well-Being and Underlying Mechanisms

Problematic social media use is detrimental to users' subjective well-being. Based on cognitive behavioral therapy (CBT), we proposed a short-term abstinence intervention to treat this problem. A mixed method study with 65 participants was conducted to examine the effectiveness of this intervention and to reveal the underlying mechanisms of how the intervention influences participants. While the experimental group (N = 33) took eight 2.5-h breaks from social media over two weeks and had daily dairies, the control group (N = 32) used social media as usual and had daily diaries. The results demonstrated that the intervention has a positive effect on life satisfaction. The effect varied with the time users conducted abstinence (work hours vs. off hours) and the level of social media addiction (heavy users vs. normal users). Qualitative findings from dairies and interviews unveiled associations among users' behaviors, feelings, and cognitions during and after abstinence. These results extend the understanding of the CBT-based short-term abstinence intervention and suggest opportunities to alleviate problematic social media use.

The patterns of problematic social media use (SMU) and their relationship with online flow, life satisfaction, depression, anxiety and stress symptoms in Lithuania and in Germany

The present study investigated problematic social media use (SMU) in Lithuania and in Germany. In two student samples (Lithuania: N = 1640; Germany: N = 727), problematic SMU, flow experienced during SMU, life satisfaction, depression, anxiety and stress symptoms were assessed by online surveys. Latent Class Analysis resulted in a four-group classification of participants due to their levels of problematic SMU characteristics: low-symptom, low-withdrawal, high-withdrawal, and high-symptom. The proportion of participants in the low-symptom group was significantly higher in Germany than in Lithuania. In contrast, significantly more Lithuanian participants belonged to both withdrawal groups. No significant country differences were found for the composition of the high-symptom group. In both countries, a series of Structural Equation Models showed that the level of flow, depression, anxiety and stress symptoms was the highest in the high-symptom group, and the lowest in the low-symptom group. Life satisfaction revealed the reversed result pattern. The current findings show that students from Lithuania and Germany can be grouped considering their problematic SMU level. Individuals in the four groups differ due to their level of mental health. Especially members of the high-symptom group might benefit from external controlling strategies of their time spent on SM, while members of the withdrawal groups are suggested to train their SMU self-control.

The relationship between burden caused by coronavirus (Covid-19), addictive social media use, sense of control and anxiety

The outbreak of Covid-19 has significantly restricted people's everyday life and contributed to enhanced social media use (SMU). The present study investigated the relationship of burden caused by Covid-19 and addictive SMU. Data were assessed in a sample of 550 users of social media (age: M (SD) = 27.08 (6.74)) from Germany via online surveys in spring 2020. In a moderated mediation analysis, the positive association between burden and addictive SMU was significantly mediated by the level of perceived sense of control. Anxiety symptoms significantly moderated the relationship between sense of control and addictive SMU. Specifically, the link between both variables was significant only for medium and high levels of anxiety symptoms. The present findings disclose the mechanisms that can contribute to the development of addictive tendencies during the pandemic outbreak. Potential practical implications and ways of how the negative consequences of burden caused by Covid-19 might be prevented are discussed.

PHYSICAL ACTIVITY LEVEL OF FACEBOOK USERS

ABSTRACT Introduction: Interactions of Facebook users led to a study of the influence that users can exert on behavioral changes for a healthier life. Objective: To analyze the behavior of Facebook users in order to define the Users' Behavioral Patterns, by monitoring the practice of physical activities shared online, aided by a social competition among users, with the aim of combating sedentarism through the modern attraction of technology and gamification. Methods: A computational tool was developed to extract data from physical activity shared online. The tool, named FitRank, has permissions to access users' data. Tables and classifications were generated based on an analysis of the data in the database, using decision tree algorithms and descriptive statistical analysis. Results: users were classified according to sociodemographic data, and data on the creation of competitive rankings and the practice of physical activities, including the definition of the User's Behavioral Pattern. Conclusion: The study suggested the importance of technological innovations to combat sedentarism, in line with current social entertainment technologies to make them more enjoyable and motivating for the regular practice of physical activities and to provide a better quality of life.
