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

Large-Scale Deep Learning-Enabled Infodemiological Analysis of Substance Use Patterns on Social Media: Insights From the COVID-19 Pandemic

BACKGROUND

The COVID-19 pandemic intensified the challenges associated with mental health and substance use (SU), with societal and economic upheavals leading to heightened stress and increased reliance on drugs as a coping mechanism. Centers for Disease Control and Prevention data from June 2020 showed that 13% of Americans used substances more frequently due to pandemic-related stress, accompanied by an 18% rise in drug overdoses early in the year. Simultaneously, a significant increase in social media engagement provided unique insights into these trends. Our study analyzed social media data from January 2019 to December 2021 to identify changes in SU patterns across the pandemic timeline, aiming to inform effective public health interventions.

OBJECTIVE

This study aims to analyze SU from large-scale social media data during the COVID-19 pandemic, including the prepandemic and postpandemic periods as baseline and consequence periods. The objective was to examine the patterns related to a broader spectrum of drug types with underlying themes, aiming to provide a more comprehensive understanding of SU trends during the COVID-19 pandemic.

METHODS

We leveraged a deep learning model, Robustly Optimized Bidirectional Encoder Representations from Transformers Pretraining Approach (RoBERTa), to analyze 1.13 billion Twitter (subsequently rebranded X) posts from January 2019 to December 2021, aiming to identify SU posts. The model's performance was enhanced by a human-in-the-loop strategy that subsequently enriched the annotated data used during the fine-tuning phase. To gain insights into SU trends over the study period, we applied a range of statistical techniques, including trend analysis, k-means clustering, topic modeling, and thematic analysis. In addition, we integrated the system into a real-time application designed for monitoring and preventing SU within specific geographic locations.

RESULTS

Our research identified 9 million SU posts in the studied period. Compared to 2019 and 2021, the most substantial display of SU-related posts occurred in 2020, with a sharp 21% increase within 3 days of the global COVID-19 pandemic declaration. Alcohol and cannabinoids remained the most discussed substances throughout the research period. The pandemic particularly influenced the rise in nonillicit substances, such as alcohol, prescription medication, and cannabinoids. In addition, thematic analysis highlighted COVID-19, mental health, and economic stress as the leading issues that contributed to the influx of substance-related posts during the study period.

CONCLUSIONS

This study demonstrates the potential of leveraging social media data for real-time detection of SU trends during global crises. By uncovering how factors such as mental health and economic stress drive SU spikes, particularly in alcohol and prescription medication, we offer crucial insights for public health strategies. Our approach paves the way for proactive, data-driven interventions that will help mitigate the impact of future crises on vulnerable populations.

Viral Transmission? A Longitudinal Study of Media Use and Its Relation to Mental Strain During the First 2 Years of the COVID-19 Pandemic

BACKGROUND

In light of the dynamic COVID-19 pandemic, the exposure to pandemic-related media coverage may change over time and may be particularly relevant due to associations with psychopathological symptoms. The aims of the present study were to examine changes in media consumption over time and to analyze its prospective associations with psychological strain.

METHOD

The study uses a longitudinal observational design with ten periods of online data collection from March 2020 to April 2022 in an adult convenience sample (N = 8337) of the general population in Germany.

RESULTS

Our data revealed that the frequency and duration of pandemic-related media exposure as well as their subjective critical evaluation showed the highest levels at the beginning of the pandemic and peaked again in autumn 2020 and spring 2021. The primarily used media formats changed only slightly over time. The amount of media exposure at baseline was associated with more impairing pandemic-related anxiety 1 month, 1 year, and 2 years later.

CONCLUSION

Our results hint to potentially problematical and long-lasting associations of pandemic-related media consumption with mental strain. Our findings could serve as an orientation for recommendations, further research, and adequate interventions for a responsible dealing with media coverage.

Contextualizing Changes in e-Cigarette Use During the Early COVID-19 Pandemic and Accompanying Infodemic ("So Much Contradictory Evidence"): Qualitative Document Analysis of Reddit Forums

BACKGROUND

Understanding how social media platforms facilitate information exchange and influence behavior during health crises can enhance public health responses during times of uncertainty. While some risk factors for COVID-19 susceptibility and severity (eg, old age) were clear, whether e-cigarette use increased risk was not clear. People who used e-cigarettes had to navigate both the COVID-19 infodemic and a conflicting, politicized, and changing information environment about the interaction between COVID-19 and e-cigarette use.

OBJECTIVE

This study aims to characterize and contextualize e-cigarette-related behavior changes during the early COVID-19 pandemic and illuminate the role that social media played in decision-making.

METHODS

We conducted a qualitative analysis of COVID-19-related e-cigarette discussions on 3 Reddit forums about e-cigarettes. We collected 189 relevant discussion threads made in the first 6 months of the pandemic (collected from June 27, 2020, to July 3, 2020). Threads included 3155 total comments (mean 17 comments) from approximately 1200 unique Redditors. We developed and applied emergent codes related to e-cigarette perceptions and behaviors (eg, the role of nicotine in COVID-19 and do-it-yourself narratives) and web-based community interactions (eg, advice), identified thematic patterns across codes, and developed a model to synthesize the socioecological context of e-cigarette behaviors.

RESULTS

e-Cigarette subreddits provided a platform for Redditors to discuss perceptions and experiences with e-cigarettes, make sense of information, and provide emotional support. Discussions reflected an array of e-cigarette-related behavioral responses, including increases and decreases in use intensity, changes in purchasing practices (eg, stockpiling), and changes in vaping practices (eg, reusing disposable pods). This study presented a theoretically and empirically informed model of how circumstances created by the pandemic (eg, changes in activity space and product shortages) compelled behavior changes. Redditors drew from their existing perceptions, intentions, and experiences with nicotine and tobacco products; their personal pandemic experiences; and their participation on Reddit to decide whether and how to change their e-cigarette behaviors during the early pandemic. Forums reflected uncertainty, stress, and debate about the rapidly evolving and complicated public health information. Consumption and discussion of media (eg, news articles and peer-reviewed publications) on Reddit informed e-cigarette perceptions and behaviors. Decisions were complicated by distrust of the media.

CONCLUSIONS

Variations in individual traits and environmental circumstances during the early COVID-19 pandemic provide context for why there was no unified direction of e-cigarette behavior change during this period. Information and discussion on Reddit also informed risk perceptions and decisions during the pandemic. Social media is an effective and important place to communicate public health information, particularly during crisis or disaster situations. Moving forward, transparent, accurate, and specific message development should consider the stress, struggles, and stigma of people who use e-cigarettes and address the roles mistrust and misinformation play in decisions.

Browse or broadcast? The influence of active and passive social media use on mood

Associations between screen time and mental health may be driven by increased use in young people with heightened symptoms as a means of modifying negative mood. However, the direct effect of technology use on mood remains unclear. This study aimed to investigate the effect of active and passive social media use on an induced sad or neutral mood by randomising young people (16-24 years; N = 116) to a sad or neutral mood induction task and assessing mood after being instructed to engage in active or passive social media use. We found both active and passive social media use alleviated sad mood but had no effect on neutral mood. Active social media use was associated with functional emotion regulation strategies relative to passive social media use. These findings suggest a possible beneficial effect of social media use on sad mood, however, longer-term effects on mental health are yet to be determined.

The Impact of Short-Form Video and Optimistic Bias on Engagement in Oral Health Prevention: Integrating a KAP Model

College students are recognized as a demographic particularly susceptible to higher oral health risks due to irregular and unhealthy habits. While previous research has underscored these risks through descriptive studies within this group, a significant gap persists in the literature regarding the impact of contemporary media, specifically oral-health-related content, on the engagement in oral health prevention among Chinese college students. To address this gap, this study, guided by the extended knowledge-attitude-practice (KAP) theory model, explores the direct, mediated, and serially mediated mechanisms through which exposure to oral health short-form videos on Douyin influences their participation in oral health prevention. An empirical cross-sectional online survey was conducted, with valid data (N = 421) analyzed using descriptive statistics and hierarchical regression. Mediation and serial mediation analyses were also performed using SPSS version 25.0. The analysis revealed that exposure to oral health short-form videos had a positive direct effect on both oral health knowledge and the reduction of optimistic bias among Chinese college students. Furthermore, a significant serial mediation effect of oral health knowledge and oral health attitude was identified. The findings underscore the substantial applicability and explanatory power of the extended KAP theory model in understanding engagement in oral health prevention.

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.

How Do Adherence to COVID-19 Mitigation Measures and Its Predictors Change between 2020 and 2021? An Explorative Investigation in Eight European Union and Non-European Union Countries

INTRODUCTION

Adherence to COVID-19 mitigation measures is an important vehicle that has contributed to the fight against the pandemic. The present study investigated potential changes of the level of adherence and its predictors between 2020 and 2021 in eight countries.

METHODS

Adherence to COVID-19 measures and its potential predictors (perception of usefulness of the measures, rating of the governmental COVID-19 communication, mental health variables, COVID-19 burden) were compared between representative population samples from European Union countries (France, Germany, Poland, Spain, Sweden) and non-European Union countries (Russia, UK, USA) assessed in 2020 (N = 7,658) and 2021 (N = 8,244).

RESULTS

In the overall sample, multiple analyses of variance revealed significantly higher levels of adherence to the measures, their perception as useful, positive mental health, and feelings of being well supported and well informed by governments in 2020 than in 2021. In contrast, feelings of being left alone and symptoms of depression, anxiety, and stress were significantly higher in 2021 than in 2020. In France, Poland, Spain, and the UK, the adherence level was significantly higher in 2020 than in 2021. In European Union countries, ratings of governmental communication were less positive, and levels of mental health were lower in 2021 than in 2020. In non-European countries, an opposite result pattern was found.

CONCLUSION

The current results indicate a decrease in adherence to the mitigation measures and factors that could foster it. Potential ways how governments and authorities could enhance the population's trust in COVID-19 mitigation measures are discussed.

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.
