Internet addiction and suicidal ideation among Chinese college students: the mediating role of psychotic-like experiences

A Hybrid SEM-ANN Approach to Investigate the Internet Addiction Among University Students Based on Psychological Resilience Theory and Cognitive-Behavioral Theory

The internet is now essential in college students' lives, but its overuse is turning into a worldwide issue, notably with rising internet addiction among students. Earlier studies have mainly explored the risk factors of internet addiction, yielding various findings. This study aims to delve into the key factors affecting internet addiction among university students by integrating the theory of psychological resilience with cognitive-behavioral theory. It thoroughly analyzes how self-control, emotional regulation, social support, perceived stress, and psychological resilience influence internet addiction and explores their interactions and underlying mechanisms. The study conveniently selected 999 university students for a survey to measure their self-reported ratings on six constructs: self-control, emotional regulation, perceived stress, psychological resilience, social support, and internet addiction. Employing a Structural Equation Modeling - Artificial Neural Network (SEM-ANN) approach, the study unveiled complex and non-linear relationships between predictors and internet addiction. Results indicated that self-control and psychological resilience significantly reduce internet addiction, while perceived stress notably increases the risk. Notably, emotional regulation and social support did not directly lower the risk of internet addiction. Further analysis revealed that psychological resilience plays a mediating role between self-control, emotional regulation, social support, and internet addiction. Additionally, multilayer perceptron analysis of normalized importance showed self-control as the most critical predictive factor (100%), followed by emotional regulation (9.1%), social support (8.4%), and psychological resilience (5.4%). The study contributes theoretical and practical insights into internet addiction among university students.

The association between school bullying involvement and Internet addiction among Chinese Southeastern adolescents: a moderated mediation model with depression and smoking

Background

School bullying and Internet addiction are both common public health problems for adolescents. Several studies found an association between school bullying and Internet addiction; however, the underlying mediating and moderating mechanisms of the complex relationship between school bullying and Internet addiction are limited.

Objective

This study explored the mediating role of depression in the relationship between school bullying and Internet addiction and whether smoking moderated the relationship between school bullying and depression in Chinese southeastern adolescents.

Methods

A cross-sectional study was conducted in Guangdong Province in Southeast China in June 2021. Associations between Internet addiction, school bullying, and depression were estimated using Spearman correlation analysis, the mediation effect and moderation effect were examined using Model 4 and Model 7 in the Hayes' PROCESS macro.

Results

The results included 1992 adolescents, 23.5% and 28.0% of participants reported experiences of school bullying and Internet addiction, respectively. There was a significant correlation between school bullying, depression, and Internet addiction (p < 0.01). School bullying direct effects on Internet addiction [β = 0.565, SE= 0.053, 95% CI (0.461, 0.669)], depression partially mediated the association between school bullying and Internet addiction, with the mediation effect size being 36.5%. And smoking played a moderating role between school bullying and depression [β = -0.166, SE= 0.058, 95% CI (-0.280, -0.052)].

Conclusions

In Chinese southeastern adolescents, depression mediated the relationship between school bullying and Internet addiction, and smoking moderated the relationship between school bullying and depression.

Mediating effect of social anxiety on the association between self-esteem and internet addiction among Chinese vocational school students

Introduction

In today's digital age, concerns about internet addiction among adolescents have escalated alongside the widespread use of the internet. Simultaneously, research has spotlighted the influence of psychological factors like self-esteem and social anxiety on addictive behaviors. The aim of this study was to verify the hypothesis regarding social anxiety as a mediator in the association between self-esteem and internet addiction.

Methods

A total of 10,158 participants were randomly selected from five vocational schools in Anhui Province, China, with a mean age of 18.5 years. They completed a series of self-administered questionnaires, including the Young Internet Addiction Test (IATS), the Liebowitz Social Anxiety Scale (LSAS), and the Self-Esteem Scale (SES). Structural equation modeling (SEM) was employed to examine the mediating role of social anxiety between self-esteem and internet addiction, adjusting for demographic variables such as age, gender, and parental education.

Results

The correlation analysis revealed that self-esteem was significantly negatively correlated with internet addiction, while social anxiety was significantly positively correlated with internet addiction. The indirect effect of self-esteem on internet addiction through social anxiety was 0.11 (p < 0.01), constituting 28.35% of the total effect. Additionally, the total impact of self-esteem on internet addiction was 0.278 (p < 0.01). Subgroup analyses by age and gender confirmed the robustness of these findings, with significant total effects observed across different age groups (14-18 years: total effects = 0.637; 18-24 years: total effects = 0.744; p < 0.01) and genders (male: total effects = 0.385; female: total effects = 0.744; p < 0.01).

Discussion

The results indicate that social anxiety plays a significant mediating role in the relationship between self-esteem and internet addiction, affecting both directly and indirectly this association. These findings underscore the importance of addressing self-esteem and social anxiety in interventions aimed at reducing internet addiction among adolescents, suggesting that targeted psychological support could be pivotal in mitigating the risk of developing addictive behaviors online.

The Chain Mediating Effect of Anxiety and Inhibitory Control and the Moderating Effect of Physical Activity Between Bullying Victimization and Internet Addiction in Chinese Adolescents

This study aimed to investigate the chain mediating roles of anxiety and inhibitory control in the relationship between bullying victimization and internet addiction among Chinese adolescents, as well as the moderating effect of physical activity. A cross-sectional design was employed, sampling 1,585 adolescents from 5 provinces in China during February-March 2024. Data on bullying victimization, internet addiction, anxiety, inhibitory control, and physical activity were collected and analyzed using a moderated chain mediation model. The data suggest that bullying victimization is associated with internet addiction, and this association is also mediated by anxiety and inhibitory control. Furthermore, physical activity was found to significantly moderate the relationship between anxiety and inhibitory control. This study contributes to the understanding of how bullying victimization, anxiety, and inhibitory control are interrelated in the context of internet addiction development, with physical activity influencing this interplay. It highlights the potential of physical activity as a factor in mitigating the impact of bullying and its association with internet addiction.

The Relationship Between Empirical Avoidance, Anxiety, Difficulty Describing Feelings and Internet Addiction Among College Students: A Moderated Mediation Model

With the increasing detection rate of Internet addiction in college students, the correlation between Internet addiction and emotional problems is further strengthened. Therefore, it is crucial to actively investigate the emotional mechanisms underlying college students' internet addiction to foster their healthy development. This study establishes a moderated mediation model based on the relationships among experiential avoidance, internet addiction, anxiety, and difficulty describing feelings to explore the link between experiential avoidance and internet addiction, the mediating role of anxiety, and the moderating effect of difficulty describing feelings. The study collected data from 1,591 Chinese college students across seven provinces (municipalities), utilizing measures such as the Experiential Avoidance Questionnaire, the Internet Addiction Scale, the Anxiety Subscale, and the Difficulty Describing Feelings Scale. A cross-sectional analysis was conducted to further investigate the potential emotional mechanisms behind college students' internet addiction. The results indicated that experiential avoidance significantly predicts internet addiction among college students, with anxiety mediating the relationship between experiential avoidance and internet addiction. Additionally, difficulty describing feelings moderate the relationship between experiential avoidance and anxiety. These findings further suggest that emotional disorders such as experiential avoidance, anxiety, and difficulty describing feelings are potential risk factors behind college students' internet addiction. The study recommends enhancing psychological counseling and other intervention measures in interventions for college students' internet addiction.

Mental Health Literacy Buffers the Association Between Nightmare Distress and Psychotic-Like Experiences Among College Students

BACKGROUND

Nightmares may lead to psychotic-like experiences (PLEs). The present study aimed to examine the potential moderating and mediating effects of mental health literacy (MHL) on the association between nightmare distress (ND) and PLEs among Chinese college students.

METHODS

A total of 4000 college students who have had nightmares in the past year were assessed using the Chinese version of the nightmare distress questionnaire (NDQ-CV), mental health knowledge questionnaire (MHKQ), 15-item positive subscale of the community assessment of psychic experiences (CAPE-P15), 2-item insomnia questionnaire, 2-item patient health questionnaire (PHQ-2), and a self-compiled sample characteristics questionnaire.

RESULTS

Greater ND and lower MHL were associated with an elevated risk of PLEs among college students when adjusting for sample characteristics, insomnia and depressive symptoms. Moderation analysis indicated that MHL buffers the association between ND and PLEs, such that a higher level of MHL attenuates the positive effect of ND on PLEs to a greater extent.

CONCLUSIONS

These findings strongly stressed the urgent need for early intervention in college students with ND. Strategies should prioritise treating ND and enhancing MHL, as these may be effective approaches to preventing and reducing PLEs.

Investigating the Relationships between Internet Addiction and Suicidal Ideation in Adolescent Girls

Objective: Suicidal ideation (SI) signifies a psychiatric crisis, and individuals with SI are at a significantly higher risk of suicide attempts compared to those without. According to previous research, three factors that affect SI in adolescent girls are externalization problems, alexithymia, and perceived social support (PSS). As a result, the present research aimed to examine whether internet addiction (IA) is associated with SI through the mediating roles of PSS, externalizing problems, and alexithymia among adolescent girls in Tehran, Iran. Method: The current correlational study employed a structural equation modeling approach. Model fit indices such as the Chi-square to degrees of freedom ratio (CMIN/DF), normed fit index (NFI), root mean square error of approximation (RMSEA), Tucker-Lewis index (TLI), and goodness-of-fit index (CFI) were reported to assess the model's adequacy. A total of 441 adolescent girls were selected from high school and between the ages of 11 and 19 using a convenience sampling method. Participants completed the Multidimensional Scale of Perceived Social Support (MSPSS), the Beck Scale for Suicidal Ideation (BSSI), the Cell-Phone Over-Use Scale (COS), the Youth Self-Report (YSR), and the Toronto Alexithymia Scale-20 (TAS-20) in a written manner. Data analysis was done using SPSS 25 and AMOS 22. Results: Results revealed a significant positive correlation between IA and SI (P < 0.001). The study's most significant findings indicate that PSS, externalizing problems, and alexithymia significantly mediate the relationship between SI and IA. The coefficient of determination for the SI variable was 0.33, which means that predictor variables can explain 33% of the variance in SI (IA, PSS, alexithymia, and externalizing problems). Conclusion: IA showed direct and indirect effects on SI. Using these findings, we can elucidate the mechanism of how IA affects individual SI, providing critical information for the development and implementation of targeted strategies and interventions to reduce SI among Iranian adolescent girls. Psychological interventions that address the role of externalizing behaviors, alexithymia, and PSS in adolescents with IA may help reduce SI.

Correlations between problematic internet use and suicidal behavior among Chinese adolescents: a systematic review and meta-analysis

Background

Problematic Internet Use (PIU) has been increasingly linked to suicidal behavior among adolescents, raising significant public health concerns, particularly in Chinese youth. This study aimed to systematically review and meta-analyze the correlation between PIU and suicidal behavior in Chinese adolescents to provide a clearer understanding of this association.

Methods

A comprehensive search was conducted across seven databases up to July 1, 2024. Studies investigating the relationship between PIU and suicidal behavior among Chinese adolescents were included. A random-effects meta-analysis was employed to assess pooled effect sizes, with subgroup analyses conducted to explore potential moderators, such as geographic region, age, gender, assessment tools for PIU and suicidal ideation, and the presence of depression. Data analysis was performed using STATA software (version 16).

Results

This meta-analysis, comprising 23 studies with 353,904 participants, identified significant associations between PIU and suicidal behavior among Chinese adolescents. PIU was associated with increased risks of suicidal ideation (OR = 1.72, 95% CI: 1.45, 2.03), suicidal plans (OR = 1.50, 95% CI: 1.02, 2.20), and suicidal attempts (OR = 1.48, 95% CI: 1.16, 1.89). Subgroup analyses indicated higher risks in specific groups: adolescents from Central China (OR = 1.84, 95% CI: 1.46, 2.32), college students (OR = 2.09, 95% CI: 1.66, 2.62). The risk of suicidal ideation was particularly elevated when depression was not controlled (OR = 1.86, 95% CI: 1.53, 2.25). These findings underscore the need for targeted interventions in vulnerable populations.

Conclusion

This meta-analysis demonstrated significant associations between PIU and suicidal behaviors among Chinese adolescents. The findings emphasize the need for targeted interventions, particularly for adolescents from Central and Western China, college students, and those with untreated depression. Focused strategies are required to mitigate the risks associated with PIU and to effectively address suicidal behaviors in these high-risk populations.

The relationship between childhood trauma and mental health status among Chinese vocational high school adolescents: the mediating effect of poor self-control and internet addiction

BACKGROUND

Mental health problems among adolescents are a common concern globally. However, its relationship with childhood trauma is not clearly understood from the existing studies. Therefore, this study aims to explore the relationships among childhood trauma, mental health, self-control, and internet addiction in Chinese vocational high school students.

METHODS

A cross-sectional survey was conducted among vocational high school students in China from October 2020 to December 2020. Standardized questionnaires were used to collect basic information regarding childhood trauma, self-control, psychological state, and social demographics. A structural equation model was used to study the relationships among internet addiction, self-control, childhood trauma, and mental health.

RESULTS

A total of 3368 individuals participated in the study. The results revealed the mediating effects of poor self-control and internet addiction on the association between childhood trauma and mental health.

CONCLUSIONS

Internet addiction and low self-control play mediating roles in childhood trauma and mental health. Clarifying these relationships will help formulate better-targeted interventions to improve the mental health of Chinese vocational high school students and aid in interventions to treat and prevent mental health problems.

Supervisor's neuroticism and problematic Internet use among graduate students: the mediating role of supervisor-student relationship quality and the moderating role of fear of the supervisor's negative evaluation

BACKGROUND

Graduate students exhibit vulnerability to problematic Internet use, which can result in adverse physical, psychological, and social consequences. However, limited studies have addressed this issue among graduate students, and even fewer have explored the unique factors contributing to their problematic Internet use. Therefore, to address this gap, the current study aims to probe the relationship between supervisor's neuroticism and problematic Internet use among graduate students, the mediating effect of the supervisor-student relationship quality, as well as the moderating effect of fear of the supervisor's negative evaluation.

METHODS

A cross-sectional study was conducted in 2018 at three universities in Beijing, China. Anonymous data from 448 graduate students were collected regarding problematic Internet use, supervisor's neuroticism, supervisor-student relationship quality, and the fear of the supervisor's negative evaluation. A moderated mediation analysis was performed using Hayes' PROCESS macro (Model 14).

RESULTS

Supervisor's neuroticism was positively linked to graduate students' problematic Internet use, supervisor-student relationship quality mediated the linkage, and fear of the supervisor's negative evaluation played a moderating role in the second stage. Specifically, for students lower in fear of the supervisor's negative evaluation, supervisor-student relationship quality negatively predicted students' problematic Internet use. While for the graduate students higher in fear of the supervisor's negative evaluation, supervisor-student relationship quality could not significantly predict students' problematic Internet use. The mediating effect was only significant for graduate students lower in fear of the supervisor's negative evaluation.

CONCLUSIONS

This study established a theoretical model linking supervisor's neuroticism to graduate students' problematic Internet use, highlighting the potential roles of supervisor-student relationship quality and fear of the supervisor's negative evaluation. Reducing the neuroticism level of the supervisor, enhancing the quality of the supervisor-student relationship, and mitigating students' fear of the supervisor's negative evaluation will contribute to the reduction of problematic Internet use among graduate students.

Internal consistency and temporal stability of the Community Assessment of Psychic Experiences (CAPE): A reliability generalization meta-analysis

Psychotic experiences (PE) are prevalent in general and clinical populations and can increase the risk for mental disorders in young people. The Community Assessment of Psychic Experiences (CAPE) is a widely used measure to assess PE in different populations and settings. However, the current knowledge on their overall reliability is limited. We examined the reliability of the CAPE-42 and later versions, testing the role of age, sex, test scores, and clinical status as moderators. A systematic search was conducted on the Scopus, Web of Science, PubMed, EBSCOhost, ProQuest, and GoogleScholar databases. Internal consistency and temporal stability indices were examined through reliability generalization meta-analysis (RGMA). Moderators were tested through meta-regression analysis. From a pool of 1,015 records, 90 independent samples were extracted from 71 studies. Four versions showed quantitative evidence for inclusion: CAPE-42, CAPE-20, CAPE-P15, and CAPE-P8. Internal consistency indices were good (α/ω≈.725-0.917). Temporal stability was only analyzed for the CAPE-P15, yielding a moderate but not-significant effect (r=0.672). The evidence for temporal stability is scant due to the limited literature, and definitive conclusions cannot be drawn. Further evidence on other potential moderators such as adverse experiences or psychosocial functioning is required.

Excessive internet use as a risk factor for suicide ideation among university students in Malawi: A cross-sectional study

Background

Covid 19 has fast-paced the use of technological innovations, mainly the internet. However, Internet use can lead to several behavioral and psychological conditions, such as cyberbullying and distorted relationships, which could lead to suicide ideation. Suicide is the second leading cause of death among young adults.

Aim

To assess the association between Internet addiction and suicide ideation among university students in Malawi. Furthermore, to assess the factors associated with suicidal thoughts among Malawian college students who surf the World Wide Web.

Methods

This cross-sectional study utilized secondary research and used data available from https://data.mendeley.com/drafts/xbfbcy5bhv. Internet addiction was measured using the Internet Addiction Test. The dependent variable includes suicide ideation. Binary logistic regression was used to analyze the relationship between the dependent and independent variables. The value of p < 0.05 was considered statistically significant.

Results

Out of the 620 participants, 514 (82.2%) were aged between 15 and 24. The majority were males 401 (64.7%). The mean IAT score was 46.08 (SD = 14.60). The IAT score was 44.81 (SD = 13.85) among males and 48.40 (SD = 15.65) among females (p = 0.003). About 341 (55%) of students use the internet excessively. Suicide ideation was prevalent among 101 (16.3%) of the students. Suicide ideation was significantly associated with internet addiction. (p < 0.001). The odds of developing suicidal thoughts increased about 3 times among excessive internet users compared to average users (OR = 2.91, 95% CI = 1.213-7.018). However, age, gender, discipline, and year of study were not associated with suicide ideation.

Conclusion

The study suggests that internet addiction affects suicide ideation mainly through distorting social relationships. School settings should increase awareness regarding the safe use of the internet to ensure a balance between online and real-life interactions and curb suicide.
