The Impact of Social Media Use on Sleep and Mental Health in Youth: a Scoping Review.

PURPOSE OF REVIEW: Social media use (SMU) and other internet-based technologies are ubiquitous in today's interconnected society, with young people being among the commonest users. Previous literature tends to support that SMU is associated with poor sleep and mental health issues in youth, despite some conflicting findings. In this scoping review, we summarized relevant studies published within the past 3 years, highlighted the impacts of SMU on sleep and mental health in youth, while also examined the possible underlying mechanisms involved. Future direction and intervention on rational use of SMU was discussed. RECENT FINDINGS: Both cross-sectional and longitudinal cohort studies demonstrated the negative impacts of SMU on sleep and mental health, with preliminary evidence indicating potential benefits especially during the COVID period at which social restriction was common. However, the limited longitudinal research has hindered the establishment of directionality and causality in the association among SMU, sleep, and mental health. Recent studies have made advances with a more comprehensive understanding of the impact of SMU on sleep and mental health in youth, which is of public health importance and will contribute to improving sleep and mental health outcomes while promoting rational and beneficial SMU. Future research should include the implementation of cohort studies with representative samples to investigate the directionality and causality of the complex relationships among SMU, sleep, and mental health; the use of validated questionnaires and objective measurements; and the design of randomized controlled interventional trials to reduce overall and problematic SMU that will ultimately enhance sleep and mental health outcomes in youth.

I rely on a little help from my friends: the effect of interpersonal and intrapersonal emotion regulation on the relationship between FOMO and problematic internet use.

BACKGROUND: This study investigated the role of emotion regulation in relation to the links between fear of missing out (i.e., FOMO) and two components of problematic internet use: problematic social media use and doomscrolling. METHODS: Participants (N = 603, Mage = 30.41, SDage = 7.64; 49.1% male-identifying) completed measures of fear of missing out, intrapersonal and interpersonal emotion regulation, and problematic social media use, and doomscrolling. A parallel mediation model was tested to examine the nature of the associations between fear of missing out, intrapersonal, and interpersonal emotion regulation, in accounting for variance in the outcome measures. RESULTS: Analyses revealed that the effect of fear of missing out on problematic social media use was fully mediated by both intrapersonal and interpersonal emotion regulation. In contrast, the effect on doomscrolling was fully mediated by intrapersonal emotion regulation only. CONCLUSIONS: Findings clarify the role of emotion regulation in explaining the relationship between fear of missing out and two types of problematic internet use, indicating a need to consider individual differences in emotion regulation in an evolving social media landscape.

Partner's problematic social media use, woman's time perspective, and prenatal depression.

PURPOSE: Using social media can have negative consequences. The present study aimed to examine how the partner's problematic social media use (SMU) was related to the pregnant woman's time perspective and prenatal depression. METHODS: The study included 30 pregnant women and their 30 male partners. Research was conducted twice: in the first and third trimesters of pregnancy. Women completed online measures: the Zimbardo Time Perspective Inventory Fatalism scale (ZTPI-Fat), the Dark Future Scale (DFS), and the Edinburgh Postpartum Depression Scale (EPDS). Men completed the online Social Media Addiction Questionnaire (SMAQ). RESULTS: The woman's depressive symptoms were positively associated with fatalism (r = .35, p < .01 in the first trimester; r = .49, p < .01 in the third trimester) and future negative perspective (r = .33, p < .05 in the first trimester; r = .77, p < .001 in the third trimester). Moreover, in the third trimester, women's depressive symptoms correlated positively with their partners' problematic SMU (r = .36, p < .05) and negatively with their financial situation (r = - .37, p < .05). The results of the mediation analyses showed that the more intensive the partner's problematic SMU, the stronger the pregnant woman's fatalism and, consequently, the stronger her future negative perspective, resulting in more severe prenatal depressive symptoms in the third trimester (indirect effect: ß = .16, SE = .09, 95% CI [.021, .393]). CONCLUSIONS: Our findings show how important the behavior of the partner is for the mental health of the pregnant woman. The results suggest a possible mechanism explaining the relationship between the partner's problematic SMU and the woman's prenatal depressive symptoms. This mechanism probably consists in increasing the woman's sense of helplessness and loss of control over life, which leads to intensified future anxiety and, consequently, to depressive symptoms. Moreover, we interpreted the results to mean that the partner's time-consuming preoccupation with SMU may make the woman feel emotionally neglected. The lack of support from the partner may give rise to feelings of powerlessness, and may cause depressive symptoms.

The mediating and moderating effects of psychological distress on the relationship between social media use with perceived social isolation and sleep quality of late middle-aged and older adults.

OBJECTIVES: Older adults are more likely to have poor sleep quality and be socially isolated. The present study examined the potential benefits and disadvantages of social media use (SMU) with respect to sleep quality and perceived social isolation among Iranian late-middle-aged and older adults with focus a on both the mediating and moderating role of psychological distress. METHODS: A population-based cross-sectional study was conducted among 900 older community-dwellers living in Shiraz using a structured questionnaire. Social media use was assessed by estimating the frequency of social networking site visits per week. Data concerning self-rated physical health, chronic medical and mental health conditions, perceived social isolation, sleep quality, and psychological distress were also collected. Multiple linear regression was used to identify independent variables associated with outcomes. Then, mediation and moderation models were used to examine the potential mediating and moderating effects of psychological distress and SMU on their relationships with the study variables. RESULTS: Higher social media use was associated with better sleep quality and less perceived social isolation. Nevertheless, the relationships between SMU and participants' sleep quality and perceived social isolation were largely mediated by their level of psychological distress. Furthermore, SMU had a significant moderating effect in the relationship between the psychological distress and the levels of perceived social isolation, so that participants with higher frequency of SMU per week felt less loneliness. CONCLUSIONS: The study findings suggest that SMU has a positive buffering effect regarding late middle-aged and older adults' mental health mainly through moderation of their perceived social isolation. The mediating role of psychological distress in research examining the relationship between SMU and older adults' mental health outcomes should be considered in future research.

How the social media impact women's psychological well-being in the patriarchal structure? The moderating effect of social capital.

BACKGROUND: Despite technological, political and economic progress, Pakistan is still a traditionally patriarchal society, and cultural norms curb women's freedom of socialization, which contributes to poor mental health. The digital technology spaces are rampant with male dominance, and offline cultural behaviours are replicated. Therefore, the current research in Pakistan intends to focus solely on women, their social media uses and the consequent impact on their psychological well-being. Furthermore, the mediation role of social capital is explored, which is linked to women's socialization. In virtual communication, women can expand their connection or remain limited to known people. METHODS: An online survey collected 240 responses from women social media users. The questionnaire was divided into demographics, social media use patterns like access, online time, frequency of use, social media uses, online social capital and psychological well-being. The obtained responses were statistically analyzed using Smart PLS. RESULTS: Pakistani women use social media extensively; however, their uses are culturally influenced. The women use social media and socialize online but do not openly disclose their personalities and emotions to extend the connection. They seek information only from acquaintances and do not trust newly developed online contacts. Therefore, the mediation role of bonding social capital is significant, referring to the importance of close ties and trust in psychological well-being. Though virtual spaces provide an opportunity for bridging social capital, women use social media for socialization; however, it doesn't contribute to women's psychological well-being. CONCLUSION: Despite the higher penetration of digital technologies, cultural power still rules in developing countries like Pakistan. Social media uses are gender- and culturally specific, contributing to psychological well-being and developing social capital. The results from Pakistani society recommend ensuring a secure digital experience for women to get maximum benefits from social media and enhance their psychological well-being.

Association between health-related social media use and E-cigarette use among current cigarette users: the roles of anti-tobacco messages and harm perception.

BACKGROUND: The popularity of e-cigarettes is on the rise among current cigarette users. Therefore, there are concerns about their health implications. This study examined the impact of health-related social media use on e-cigarette use among current cigarette users. It assesses the mediating influence of online anti-tobacco messages and the moderating role of the harm perception of e-cigarettes. METHODS: This study was focused on 563 current cigarette users from the 2022 Health Information National Trends Survey (HINTS). Three tasks were performed: (1) assessing the direct and indirect impacts of health-related social media use on e-cigarette use among current cigarette users, (2) exploring the mediating role of exposure to online anti-tobacco messages, and (3) examining the moderating influence of e-cigarette harm perception on the path from anti-tobacco messages to e-cigarette use. RESULTS: Health-related social media use was positively associated with current cigarette users' e-cigarette use directly (bp = 0.183, p < .01) and indirectly through exposure to online anti-tobacco messages (bp = 0.023, 95% CI: [0.001, 0.051]). Harm perception of e-cigarettes moderated the relationship between online exposure to anti-tobacco messages and e-cigarette use (bp=-0.467, p < .01). The relationship appeared weaker for individuals who perceived greater harm from e-cigarettes. CONCLUSIONS: Health-related social media use positively correlates with e-cigarette use among current cigarette users through exposure to online anti-tobacco messages. The perceived harm of e-cigarettes moderates this indirect path. These findings have implications for public health interventions aimed at smoking cessation.

Clarifying the relationship between insecure attachment and problematic social media use across platforms: a network analysis.

BACKGROUND: Despite evidence suggesting that insecure attachment is a significant risk factor for Problematic Social Media Use (PSMU), there remains a lack of comprehensive studies exploring this relationship, and a unified understanding of its role has yet to be established. METHODS: We employed network analysis to construct an integrated model for examining the complex interrelations between negative emotions, trait and state attachment, motives, and PSMU across three platforms (i.e., WeChat, Sina Weibo, and TikTok), as well as for identifying potential mediating variables between attachment and PSMU. Data were collected from 685 young adults via online self-reported questionnaires. RESULTS: We found that negative emotions are positively correlated with insecure trait and state attachment but have a negligible direct relationship with PSMU. The conformity motive and state attachment security emerged as important central nodes when measured by strength, closeness, and betweenness. Moreover, attachment states and motives were found to be clustered. Such strong interrelationships were also evident between insecure attachment and PSMU, while trait attachment anxiety and avoidance were observed to be related to PSMU across various platforms. CONCLUSIONS: Our findings promote a deeper understanding of the relationship between insecure attachment and PSMU from a cross-platform perspective and offer novel insights into the mechanisms underlying their co-occurrence, which may guide the development of effective interventions for healthier social media engagement.

Examining the Association between Social Media Use and Dietary Habits among College Students in Riyadh, Saudi Arabia.

Food culture plays a vital role in societal dynamics, with various factors influencing dietary choices beyond hunger. Among these factors are external eating, triggered by environmental cues, and emotional eating, which are common stress-coping mechanisms among college students. Social media has a significant impact on nutrition by providing access to food-related content, which can lead to restrictive diets or unhealthy eating habits. High social media engagement is associated with an increased risk of chronic diet-related conditions such as metabolic syndrome. This study investigated the association between social media use and dietary habits among college students in Riyadh, Saudi Arabia. The cross-sectional study surveyed 401 participants online. The findings revealed that 74.6% of participants were women, with a mean age of 20.75 years. A significant portion (51.9%) reported spending over four hours daily on social media, with TikTok, Instagram, and YouTube being the primary sources of nutritional information. Statistical analysis indicated significant differences in dietary scores related to having children, medical conditions, and social media usage time. This study highlights the negative impact of extensive social media use on dietary habits and suggests the need for targeted public health interventions. Recommendations include promoting reliable nutrition-related content on social media, offering affordable healthy food options on campuses, and conducting further research to establish causality between social media use and dietary habits.

Engaging with Social Media: Implications for COVID-19 Research Participation Among Adults Living in the State of Florida.

The COVID-19 pandemic led to an increased use of social media, with many people turning to it for social support. Given the varying effects of social media, this study examines how social media use influences the willingness of adults in the State of Florida to participate in COVID-19-related research. The study used data collected through the Florida Statewide Registry for Aging Studies (FSRAS), which included 587 participants who were 25 years and older. The primary outcome variables were COVID-19 treatment and COVID-19 vaccine research. Ordinal logistic regression was used to evaluate the association between social media use and willingness to participate in COVID-19 treatment and vaccination research, adjusting for sociodemographic variables. The analysis did not find a statistically significant relationship between social media use and the likelihood of participating in COVID-19 research. However, significant differences were observed across racial/ethnic groups. Participants who identified as "Hispanic/Latino" (OR-2.44, 95% CI-1.11-5.35, p = 0.03) and "Other" (OR-12.51, 95% CI-1.98-79.22, p = 0.01) were significantly associated with willingness to participate in a COVID-19 treatment research. Similarly, participants of all other races/ethnicities were significantly more willing to participate in research testing COVID-19 vaccines. Additionally, females were more likely to express willingness to participate in COVID-19 vaccine research. Social media use did not significantly affect willingness to participate in COVID-19 treatment and vaccine research; however, racial and ethnic differences significantly influenced willingness to participate. These findings suggest that implementing targeted culturally sensitive recruitment strategies and community engagement efforts can improve participation in COVID-19 research.

Using Short-Form Videos to Get Clinical Trial Newcomers to Sign Up: Message-Testing Experiment.

BACKGROUND: Recruiting participants for clinical trials poses challenges. Major barriers to participation include psychological factors (eg, fear and mistrust) and logistical constraints (eg, transportation, cost, and scheduling). The strategic design of clinical trial messaging can help overcome these barriers. While strategic communication can be done through various channels (eg, recruitment advertisements), health care providers on the internet have been found to be key sources for communicating clinical trial information to US adults in the social media era. OBJECTIVE: This study aims to examine how communication source (ie, medical doctors and peers) and message framing of TikTok videos (ie, psychological and logistical framing) influence clinical trial-related attitudes, perceptions, and sign-up behaviors under the guidance of the integrated behavioral model. METHODS: This study used a 2 (source: doctor vs peer) × 2 (framing: psychological vs logistical) between-participant factorial design web-based experiment targeting adults in the United States who had never participated in clinical trials (ie, newcomers). A Qualtrics panel was used to recruit and compensate the study respondents (n=561). Participants viewed short-form videos with doctors or peers, using psychological or logistical framing. The main outcome measures included perceived source credibility, self-efficacy, attitude toward clinical trial participation, behavioral intention, and sign-up behavior. Structural equation modeling was used to analyze the direct and indirect effects of message factors on the outcome variables. Source (doctor=1; peer=0) and framing (psychological=1; logistical=0) were dummy-coded. RESULTS: Doctor-featured messages led to greater perceived source credibility (ß=.31, P<.001), leading to greater self-efficacy (95% CI 0.13-0.30), which in turn enhanced behavioral intention (95% CI 0.12-0.29) and clinical trial sign-up behavior (95% CI 0.02-0.04). Logistical barrier-framed messages led to greater self-efficacy (ß=-.09, P=.02), resulting in higher intention to participate in clinical trials (95% CI -0.38 to -0.03) and improved sign-up behavior (95% CI -0.06 to -0.004). Logistical barrier-framed messages were also directly associated with an increased likelihood of signing up for a clinical trial (ß=-.08, P=.03). The model accounted for 21% of the variance in clinical trial sign-up behavior. Attitude did not significantly affect behavioral intention in this study (ß=.08, P=.14), and psychological and logistical barrier-framed messages did not significantly differ in attitudes toward clinical trial participation (ß=-.04, P=.09). CONCLUSIONS: These findings advance our understanding of how people process popular message characteristics in short-form videos and lend practical guidance for communicators. We encourage medical professionals to consider short-form video sites (eg, TikTok and Instagram Reels) as effective tools for discussing clinical trials and participation opportunities. Specifically, featuring doctors discussing efforts to reduce logistical barriers is recommended. Our measuring of actual behavior as an outcome is a rare and noteworthy contribution to this research.

Scrolling through adolescence: a systematic review of the impact of TikTok on adolescent mental health.

Amidst rising concerns about mental health in adolescents, the role of social media (SM), particularly highly visual platforms such as TikTok, has become a growing focus of investigation. In the extant literature, conclusive evidence is limited by the aggregate analysis of very heterogeneous SM platforms. This systematic scoping review examines the relationship between TikTok and mental health in adolescents. Additionally, it aims to highlight potential interactions between typical developmental processes and the unique aspects of TikTok, exploring their relevance to mental health within this demographic. Following PRISMA guidelines, a systematic search across PubMed, Scopus, Web of Knowledge, and PsychINFO yielded 20 studies that met the inclusion criteria, encompassing a total of 17,336 subjects from 10 countries. The retrieved studies analyzed four main topics related to TikTok use, i.e., the overall impact on adolescents' mental health, risk of problematic use and behavioral addiction, consequences on body image and self-esteem, and possible spreading of mental illness behaviors. While TikTok offers creative opportunities for self-expression and peer connection, the literature raises concerns about its potential negative effects on teens, such as lower life satisfaction, increased risk of "contagion" of certain psychiatric symptoms, and problematic usage patterns. Significant variations in study methodologies and outcome measures were observed. In the current era of evolving SM landscapes, a comprehensive approach informed by developmentally grounded research is critically needed to further understand the interplay between SM and adolescent mental health, providing insights for health authorities and policymakers.

Self-disgust mediates the effect of problematic mobile social media use on non-suicidal self-injury in adolescents: A latent growth curve analysis.

OBJECTIVE: Previous research linked problematic mobile social media use to non-suicidal self-injury (NSSI). However, little research explored the underlying mechanism. Drawing on the social displacement hypothesis, which suggests that excessive social media use may disrupt offline social interactions, leading to negative emotional experiences, the study employs a longitudinal design to explore the relationship between problematic mobile social media use and NSSI, with a specific emphasis on the mediating role of self-disgust. METHODS: A total of 1,684 Chinese adolescents (52.3% females; Mage = 14.59 years, SDage = 1.27) completed self-report questionnaires regarding problematic mobile social media use, self-disgust, and NSSI. The assessment was conducted in three waves, 6 months apart. RESULTS: Using latent growth curve and structural equation modeling, our study observed a consistent linear decline in NSSI levels over time. Higher initial NSSI levels correlated with a slower reduction. Problematic mobile social media use positively influenced the initial level of NSSI. Additionally, self-disgust played a mediating role in the relationship between problematic mobile social media use and NSSI. CONCLUSIONS: The study underscores the importance of understanding the emotional experiences behind social media use, beyond mere usage duration. By revealing the mediating role of self-disgust, it provides new insights into the complex interplay between problematic mobile social media use and adolescent NSSI.

Psychological distress, social media use, and academic performance of medical students: the mediating role of coping style.

BACKGROUND: Given that social media use (SMU) is an increasingly widespread activity among university students, more information is needed to evaluate its relationship with students' mental health, particularly medical students. OBJECTIVE: The present study assessed the relationships between SMU and coping style with psychological distress and academic performance of medical students. METHODS: An offline cross-sectional survey conducted with 398 undergraduate medical students. The survey collected data on demographics, psychological distress (DASS-21), coping strategies (Brief COPE Scale), academic performance (grade point average) and estimated average time spent on social media per day. Structural equation modeling was used to clarify relationships between the main study variables. The study also examined the mediating effect of maladaptive coping between SMU and psychological distress. RESULTS: Students with higher levels of psychological distress were more likely to be engaged in frequent social media use. Spending more than two hours a day on social media use had a positive association with maladaptive coping (p < 0.001), particularly with substance use and behavioral disengagement both of which could negatively affect academic performance. Maladaptive coping mediated the relationship between students' SMU and psychological distress. CONCLUSION: The findings suggest that medical students commonly use social media as a maladaptive coping tool to deal with psychological distress. Empowering students to adopt and foster appropriate coping strategies could help them to enhance resilience against life stresses and ameliorate potential long-term mental health consequences associated with maladaptive behaviors.

Does loneliness mediate the association between social media use disorder and sexual function in Lebanese university students?

Research on the association between social media use disorder (SMUD) and face-to-face sexual function remains controversial, surprisingly scarce and even non-existing in certain vulnerable populations such as university students. We aimed to explore the mediating role of loneliness between SMUD and two dimensions of sexual function (sexual arousal and desire) in a sample of Lebanese university students. A total of 363 university students participated in a cross-sectional survey. Sexual Dysfunction Questionnaire, Jong-Gierveld Loneliness Scale and Social Media Use Disorder scale were used to measure sexual function (desire and arousal), loneliness and SMUD respectively. The mediation analysis results showed that loneliness mediated the association between SMUD and sexual arousal (but not sexual desire). Higher SMUD was significantly associated with more loneliness, whereas more loneliness was significantly associated with less sexual arousal. Subsequently, higher SMUD was significantly associated with less sexual arousal. The present findings edge the university staff, clinicians, and researchers towards the psychological mechanisms that may help university students improve their sexual function, and calls for additional research in this area. Attention should be given to the possible potential role of moderating social media use in tackling loneliness and improving students' sexual function. In addition, routine sexual counseling should be considered when assessing and intervening with students having SMUD.

Bidirectional Within-Family Effects of Restrictive Mediation Practices and Adolescents' Problematic Social Media Use.

Much remains unknown about whether restrictive mediation is an effective parenting strategy to prevent or reduce problematic social media use among adolescents. Therefore, this study examined bidirectional within-family effects between two restrictive mediation practices (rule-setting and reactive restrictions) and problematic social media use using random-intercept cross-lagged panel modeling. Three-wave survey data collected among Dutch adolescents (T1: N = 1928, Mage = 13.31 years, SD = 0.91, 43.3% girl) with a 1 year-interval were used. Results showed that within-family changes in problematic social media use symptoms predicted subsequent within-family changes in perceived parental restrictive mediation. More specifically, an increase in symptoms predicted a decrease in rule-setting and an increase in reactive restrictions 1 year later. Within-family changes in perceived parental restrictive mediation practices did not predict within-family changes in problematic social media use symptoms, suggesting that the relation is unidirectional. However, concluding that limiting adolescents' Internet use is ineffective to prevent problematic social media use would be premature. Future research should investigate whether it may be an effective parenting strategy for a certain subgroup of adolescents or under certain circumstances.

Functional and dysfunctional impulsivity mediates the relationships between 'Dark Triad' traits and cyberbullying perpetration.

BACKGROUND: Cyberbullying perpetration and victimisation have been associated with psychological distress, including depression and suicidal ideation. Prior studies have shown that the 'Dark Triad' personality traits (narcissism, Machiavellianism, and psychopathy) are associated with greater likelihood of perpetration, yet there is a research gap regarding potential mediators of this relationship. AIMS: To test whether functional and dysfunctional impulsivity act as mediators between Dark Triad traits and cyberbullying perpetration. METHODS: A cross-sectional online study was conducted, in which a sample of 141 university students (63% male) from Malaysia were recruited by online and local poster advertising inviting them to complete a questionnaire containing a series of psychometric scales, including measures of 'Dark Triad' personality traits, impulsivity and cyberbullying perpetration. RESULTS: A relationship between cyberbullying perpetration and higher psychopathy scale scores was mediated by dysfunctional, but not functional, impulsivity. The relationship between cyberbullying and narcissism scores was not mediated by impulsivity. Higher Machiavellianism scores were similarly associated with cyberbullying, but there was no correlation at all between Machiavellianism and impulsivity scores. CONCLUSION: Our findings add to the literature by showing that not only Dark Triad scale scores are associated with cyberbullying, but that difficulty in refraining from or controlling impulsive behaviours (dysfunctional impulsivity) may be a key component in this relationship. Given that our sample was of generally well-functioning people, our findings may not extend to those with serious cyberbullying problems. Yet, they provide avenues for identifying people at risk of such behaviours before problems become well-established and call for more nuanced approaches towards understanding and intervening with problematic cyberbullying.

Social Media Use, Emotional Investment, Self-Control Failure, and Addiction in Relation to Mental and Sleep Health in Hispanic University Emerging Adults.

The number of social media users has increased dramatically in recent years. Common correlates of social media use may be poor mental and sleep health which are pressing issues among emerging adults and Hispanic groups. This study investigated the relationships between five different forms of social media use and mental and sleep health in Hispanic university emerging adults. Hispanic university emerging adults (n = 358) completed a survey assessing sociodemographics, overall social media use frequency, nighttime in-bed social media use, social media addiction, social media self-control failure, emotional investment in social media, depression, anxiety, stress, and sleep quality. Findings demonstrated that social media addiction and social media self-control failure were positively associated with stress and poor sleep quality. Emotional investment in social media was positively associated with depression. Findings may suggest that Hispanic university emerging adults may use social media emotionally and problematically to cope with negative affect and poor sleep quality, or that negative affect and poor sleep quality stem from using social media emotionally and problematically. The clinical implications of these results are discussed. Prospective studies are warranted to assess temporality.

The informal discussion of advance care planning among Chinese older adults: Do education and social media use matter?

This study aimed to examine and compare the associations between education, social media use, and advance care planning (ACP) discussion among Chinese older adults in mainland China (Wuhan), Taiwan (Taichung), and the United States (Honolulu). Community-dwelling older adults (≥ 55) were recruited from 2017 to 2018. The ACP discussion rate in Wuhan, Taichung, and Honolulu were 15.2 %, 19.2 %, and 31.3 %, respectively. Logistic regression models revealed that education was positively associated with ACP discussion in Taichung and Honolulu. Social media use was positively associated with ACP discussions in Wuhan and Honolulu, and it attenuated the association between education and ACP discussion in Honolulu. The present study contributes to previous studies by comparing the associations between education, social media use, and ACP discussion in different settings within the same ethnicity. Policy and practice implications were also discussed.

Impact mechanism of social-related social media use on the job performance of caregivers of older adults.

This study investigated the impact mechanism of social-related social media use on the job performance of caregivers of older adults through mental health and analyzed gender differences. A total of 358 valid questionnaires were collected and analyzed using SPSS and Smart PLS. The results showed that mental health plays an important role in the relationship between social-related social media use and job performance. Such social media use can improve psychological well-being and reduce psychological distress by promoting relaxation experience. Psychological well-being has a significant positive impact on job performance. In addition, significant differences exist in the impact path of social-related social media use on psychological distress among different gender groups. The findings of this study can assist nursing homes in assessing the use of social media within their organizations and provide methodological references for enhancing the job performance of caregivers of older adults.

Is doomscrolling related to celebrity worship? A cross-cultural study.

Building upon evidence supporting the co-occurrence of behavioural addictions, this study delved into the relationship between social media doomscrolling and celebrity worship among university student social media users in Iran and the United States. Objectives were threefold: (a) provide psychometric support for the Social Media Doomscrolling Scale (SMDS), (b) examine psychological correlates of doomscrolling and celebrity worship, and (c) explore the relationship between doomscrolling and celebrity worship. The SMDS demonstrated good psychometric properties in the US sample, like the original study of the SMDS conducted in an Iranian sample. Doomscrolling showed a positive association with future anxiety and a negative association with psychological well-being in both US and Iranian samples. Celebrity worship was positively linked with future anxiety in the Iranian and US samples. A positive correlation emerged between doomscrolling and celebrity worship in both the US and Iranian samples. This cross-cultural study offers preliminary evidence for the co-occurrence of two emerging media-related behavioural addictions.
