A serial mediation model of social media addiction and college students' academic engagement: the role of sleep quality and fatigue

Empathy and redemption: Exploring the narrative transformation of online support for mental health across communities before and after Covid-19

This study examines the impact of the COVID-19 pandemic on individuals' mental health and their online interactions, particularly within Reddit's mental health communities. By analyzing data from 15 subreddits categorized into mental health and control groups from 2018 to 2022, we observed that forums dedicated to mental health exhibited higher levels of user engagement and received more supportive responses than those in other categories. However, as the pandemic evolved, a significant decrease in online support was noted, especially within these mental health groups. This decline hints at a risk of emotional burnout among users, which poses a particularly acute challenge for individuals grappling with mental health issues. Intimate relationships have also an impact on online expression of mental health. The research underscores the pandemic's effect on online support and interaction dynamics, signaling the necessity for a deeper understanding and the development of strategies to maintain support within online communities during times of crisis.

The effects of mobile phone addiction on bedtime procrastination in university students: the masking effect of physical activity and anxiety

PURPOSE

Good sleep is one of the necessary conditions to ensure the normal performance of the physiological and psychological functions of college students. This study aimed to explore the relationship between mobile phone addiction and bedtime procrastination among Chinese college students and the mediating mechanisms of physical exercise and anxiety between the two, with a view to seek ways to prevent and intervene in college students' sleep procrastination and improve their sleep quality.

METHODS

Using SPSS 29.0 analysis with Bootstrap's method, 3,800 first-year students, sophomores, and juniors were given the Mobile Phone Addiction Tendency Scale, Bedtime Procrastination Scale, Physical Activity Scale, and Anxiety Scale. The results of the analyses included mediation tests and effect analyses of anxiety and physical activity.

RESULTS

The correlation analysis revealed significant positive correlations between mobile phone addiction and bedtime procrastination (r = 0.149, p < 0.01) as well as anxiety (r = 0.497, p < 0.01). Additionally, there was a significant negative correlation between mobile phone addiction and physical activity (r = -0.447, p < 0.01). Physical activity was also found to have significant negative correlations with anxiety (r = -0.506, p < 0.01) and bedtime procrastination (r = -0.424, p < 0.01). Furthermore, anxiety showed a significant positive correlation with bedtime procrastination (r = 0.334, p < 0.01). Physical activity and anxiety acted as substantial mediators between mobile phone addiction and nighttime procrastination. Both mediators had considerable masking effects, with the mediating effect amounting to 50.3% and 25.1%, respectively. Physical exercise and anxiety played a chain mediating role between mobile phone addiction and bedtime procrastination, and the masking effect was also significant, with a mediating effect size of 13.4%.

CONCLUSIONS

This study reveals the special characteristics of the influencing factors and pathways of bedtime procrastination in this group of college students, providing targeted evidence for the prevention and intervention of bedtime procrastination in college students. It also has an important reference value for the effects of exercise and comprehensive intervention to improve bedtime procrastination and enhance the quality of sleep in college students.

Sex differences of neural connectivity in internet gaming disorder and its association with sleep quality: an exploratory fMRI study

Objectives

Sex-specific differences in internet gaming disorder (IGD) neurophysiology remain underexplored. Here we investigated sex-related variability in regional homogeneity (ReHo) and functional connectivity (FC) in IGD and their correlations with sleep quality.

Methods

Resting-state functional magnetic resonance imaging (fMRI) scans were performed on 52 subjects with IGD and 50 healthy controls (HCs). Two-way ANOVA was used to examine sex and diagnosis interactions in ReHo and FC, followed by post-hoc analyses to explore FC biomarkers for different sexes.

Results

In ReHo analysis, the four groups showed significant sex and diagnosis interactions in the right middle frontal gyrus (rMFG). FC analysis with rMFG as the seed region revealed a significant sex and diagnosis interaction effect in FC of the rMFG with the bilateral postcentral gyrus (PoCG). In male IGD group, FC between the rMFG and the bilateral PoCG correlates strongly with daytime dysfunction score and the Pittsburgh sleep quality inventory (PSQI) total score.

Conclusion

These findings emphasize the importance of considering sexual dimorphism in the neurobiology of IGD, which might influence subsequent treatment strategies.

Status and Influencing Factors of Social Media Addiction in Chinese Workers: Cross-Sectional Survey Study

BACKGROUND

Social media addiction (SMA) caused by excessive dependence on social media is becoming a global problem. At present, most of the SMA studies recruit college students as research participants, with very few studies involving workers and other age groups, especially in China.

OBJECTIVE

This study aims to investigate the current status of SMA among Chinese workers and analyze its influencing factors.

METHODS

From November 1, 2022, to January 30, 2023, we conducted an anonymous web-based questionnaire survey in mainland China, and a total of 5176 participants completed the questionnaire. The questionnaire included the Social Networking Service Addiction Scale, Maslach Burnout Inventory-General Survey scale, Mindful Attention Awareness Scale, as well as questionnaires regarding participants' social media use habits and demographic information.

RESULTS

Through strict screening, 3468 valid questionnaires were included in this study. The main findings of this study revealed the following: the average SMA score of workers was higher (mean 53.19, SD 12.04), and some of them (393/3468, 11.33%) relied heavily on social media; there were statistically significant differences in SMA scores among workers in different industries (F14,3453=3.98; P<.001); single workers (t3106=8.6; P<.001) and workers in a relationship (t2749=5.67; P<.001) had higher SMA scores than married workers, but some married workers (214/3468, 6.17%) were highly dependent on social media; the level of SMA among female workers was higher than that of male workers (t3466=3.65; P<.001), and the SMA score of workers negatively correlated with age (r=-0.22; P<.001) and positively correlated with education level (r=0.12; P<.001); the frequency of using social media for entertainment during work (r=0.33; P<.001) and the frequency of staying up late using social media (r=0.14; P<.001) were positively correlated with the level of SMA in workers; and the level of SMA in workers was significantly positively correlated with their level of burnout (r=0.35; P<.001), whereas it was significantly negatively correlated with their level of mindfulness (r=-0.55; P<.001).

CONCLUSIONS

The results of this study suggest that SMA among Chinese workers is relatively serious and that the SMA problem among workers requires more attention from society and academia. In particular, female workers, young workers, unmarried workers, highly educated workers, workers with bad social media habits, workers with high levels of job burnout, and workers with low levels of mindfulness were highly dependent on social media. In addition, occupation is an important influencing factor in SMA. Thus, the government should strengthen the supervision of social media companies. Medical institutions should provide health education on SMA and offer intervention programs for those addicted to social media. Workers should cultivate healthy habits while using social media.

The effect of social media upward comparison on Chinese adolescent learning engagement: a moderated multiple mediation model

To investigate the mechanisms and boundary conditions of social media upward comparison on adolescents' learning engagement, this study utilized two separate approaches. In research 1, a convenience sampling method was employed to conduct a questionnaire survey among 609 adolescents. The aim was to explore the influence of social media's upward comparative tendency on learning engagement. In research 2, real social media platforms were utilized to select short videos as experimental materials. These materials were used to manipulate instantaneous social media upward comparison and examine its impact on learning engagement. The research 1's result indicated that the mediating effect of the sense of agency was significant, as well as the moderating effect of growth mindset. However, the mediating effect of positive-negative emotions was found to be insignificant.Regarding instantaneous social media upward comparison and learning engagement, positive and negative emotions were found to play a complete mediating role. However, the mediating role of agency and the moderating role of growth mindset were not significant.This study offers practical insights for educators, enabling them to develop a correct understanding and effectively regulate adolescents' use of social media.

Are "night owls" or "morning larks" more likely to delay sleep due to problematic smartphone use? a cross-lagged study among undergraduates

Sleep is an important physiological process, but staying up late has become a worldwide problem, particularly among university students. Sleep procrastination has been found to associated with sleep biorhythms and problematic smartphone use ("PSU") in previous studies. This two-wave study examines the longitudinal reciprocal relationship between PSU and sleep procrastination, together with the moderating role of sleep biorhythms. Participants comprised 1,423 Chinese university students. The results revealed that PSU and sleep procrastination are reciprocally related. Additionally, sleep biorhythms moderated this relationship, as PSU at T1 significantly predicted sleep procrastination at T2 for the morning larks group but not the night owls group. Accordingly, both PSU and sleep biorhythms should be considered when developing interventions for sleep procrastination.

Analysis on the Relationships of Smartphone Addiction, Learning Engagement, Depression, and Anxiety: Evidence from China

Background

With the popularization of the Internet and smartphones, smartphone addiction among college students is becoming increasingly common, causing the problems of their learning engagement, anxiety, and depression. The study aimed to analyze the relationships of smartphone addiction, learning engagement, anxiety and depression among Chinese college students.

Method

Based on the Self-Determination Theory, in January 2023, 780 college students from 6 universities in Heilongjiang Province in China were selected as examples for the study. Internet Addiction Test, Utrecht Work Engagement Scale-Student, Chinese version of Beck Depression Inventory-II, and Spielberger Trait Anxiety Inventory were employed to measure smartphone use, learning engagement, depression, and anxiety among college students. Pearson correlation and multiple logistic regressions were also used.

Results

Smartphone use was negatively correlated with learning engagement (r = -0.097, P < 0.001), whereas it was positively correlated with depression (r = 0.184) and anxiety (r = 0.18, P < 0.001). Significant differences were observed in learning engagement and depression and anxiety symptoms in different degrees of smartphone use. Taking severe smartphone addiction as a comparison standard, depression and anxiety symptoms had a significant influence on different levels of smartphone use, whereas learning engagement did not have a significant influence on different smartphone use levels.

Conclusion

The intervention and prevention of college students' smartphone addiction can improve their learning engagement, relieve their anxiety and depression, and enhance their mental health level.
