Internet Addiction among Adolescents May Predict Self-Harm/Suicidal Behavior: A Prospective Study

Effectiveness and satisfaction of mindfulness-based cognitive therapy for children on anxiety, depression, and internet addiction in adolescents: Study protocol for a randomized control trial

Adolescents with Internet addiction (IA) frequently encounter elevated levels of anxiety and depression, which subsequently results in the perpetuation of their addiction behaviors. Mindfulness-based cognitive therapy for children (MBCT-C) is an adapted version of traditional MBCT that targets emotional problems in children. The present study aimed to provide a framework for the implementation of a clinical trial for its effectiveness in reducing anxiety, depression, and IA in adolescents with IA. This study protocol proposes a randomized controlled trial with two parallel arms (MBCT-C versus active control). Eighty Iranian adolescents (Persian ethnicity; males and females; 12 to 15 years) diagnosed with IA will be randomly assigned to the intervention group (12 sessions of MBCT-C group therapy) or the control group (12 life skills training sessions). Pre-intervention, post-intervention, and three-month follow-up assessments will be conducted using Mindful Attention Awareness Scale-Adolescents (MAAS-A), Mindfulness Program Satisfaction Questioner (MPSQ), Reynolds Adolescent Depression Scale (RADS), State-Trait Anxiety Inventory-Children (STAI-C), MBCT-C Adherence Scale (MBCT-C-AS), and Internet Addiction Test (IAT). Data will be analyzed using mixed regression model using STATA-18 to assess the effectiveness of MBCT-C. The current study has the potential to make a significant contribution to evaluate the effectiveness of MBCT-C to address IA, anxiety, and depression in adolescents with IA.

Substance Use, Internet Risk Behavior, and Depressive Symptoms as Predictors of Self-harm Thoughts in Adolescents: Insights from the 2019 ESPAD Survey in Croatia

Self-harm has become a nonspecific symptom of mental distress that is most prevalent in the adolescent population. Since it is often a hidden problem, it is important to focus on preventing it. This study used the data from the Croatian leg of the European School Survey Project on Alcohol and Other Drugs to assess certain risk factors and possible protective factors for self-harm thoughts among 16-year-olds in Croatia. Using binary logistic regression, we identified that being female, having less family support and less parental knowledge of adolescents' activities, more frequent cannabis use, more compulsive Internet use and more frequent depressive symptoms significantly increased the likelihood of self-harm thoughts in this sample. Identifying factors that lead to thoughts of self-harm may open a potential space for self-harm prevention before those thoughts progress into behavior.

Childhood maltreatment and its dose-response relation with non-suicidal self-injury among adolescents: The mediating role of mobile phone addiction

OBJECTIVES

The associations between childhood maltreatment (CM) and mobile phone addiction (MPA), as well as non-suicidal self-injury (NSSI) have been extensively explored. However, the dose-response relationship between CM and NSSI remains inconsistent. Furthermore, there is limited understanding of the potential mediation effect of MPA on the relationship between CM and NSSI. This study aimed to explore the dose-response relationship between CM and NSSI and investigate the potential mediating role of MPA in this relationship.

STUDY DESIGN

Cross-sectional study. Cross-sectional study.

METHODS

In the cross-sectional study, a total of 21481 adolescents were selected using a multi-stage cluster sampling method in China. CM, MPA, and NSSI were obtained via self-reports. Data were analyzed using logistic regression models, restricted cubic spline (RCS) functions, and mediation models.

RESULTS

A total of 38.1 % of adolescents reported engaging in NSSI at least once. Compared with participants without CM, participants with more types of CM (cumulative childhood maltreatment, CCM) had a higher risk of NSSI (P-trend in all models <0.001). RCS further confirmed the dose-response relationships between the continuous change in CM (scores) and the risk of NSSI (P for non-linearity <0.001). Mediation analysis indicated that the relationship between CM (scores) and NSSI was mediated by MPA, and the indirect effect (β = 1.07 × 10-3, 95 % CI: 9.62 × 10-4, 1.19 × 10-3) accounted for 22.23 % of the total effect.

CONCLUSIONS

There was a dose-response relationship between CM and the NSSI, and the relationship was mediated by MPA. Interventions targeting MPA may reduce the risk of NSSI among adolescents who have experienced CM, particularly those with CCM.

The Association Between Internet Addiction and the Risk of Suicide Attempts in Chinese Adolescents Aged 11-17 Years: Prospective Cohort Study

BACKGROUND

Suicide is a critical public health issue in adolescents worldwide. Internet addiction may play a role in the increased rate of suicide attempts in this population. However, few studies have explored the relationship between pathological internet use and suicide attempts among adolescents.

OBJECTIVE

This study aimed to conduct a prospective cohort study to examine whether higher severity of pathological internet use was associated with an increased risk of suicide attempts among Chinese adolescents.

METHODS

A total of 782 adolescents were recruited from a middle school from November 2020 to December 2020 and followed up for 6 months. An online self-reported questionnaire was used to collect the participants' demographic data and assess their mental health. The Depression, Anxiety, and Stress Scale-21 items (DASS-21) was used to evaluate depression, anxiety, and stress. The Chen Internet Addiction Scale-Revised (CIAS-R) was used to assess the symptoms and severity of pathological internet use. χ2 test and ANOVA were used for intergroup comparison, and logistic regression analysis was used to examine the relationship between the severity of pathological internet use and suicide attempts. We also used a restricted cubic splines model to investigate the pattern of the association.

RESULTS

The participants had an average age of 12.59 (SD 0.64) years, with the majority being of Han ethnicity (743/782, 95.01%) and more than half being male (426/782, 54.48%). Most participants had no previous history of depression (541/782, 69.18%), anxiety (415/782, 53.07%), or stress (618/782, 79.03%). The rate of newly reported suicide attempts was 4.6% (36/782). A significant positive association was observed between internet addiction and suicide attempts (odds ratio 3.88, 95% CI 1.70-8.82), which remained significant after adjusting for age, sex, ethnicity, anxiety, depression, and stress (odds ratio 2.65, 95% CI 1.07-6.55). In addition, this association exhibited a linear pattern in the restricted cubic spline regression model.

CONCLUSIONS

This study suggested that internet addiction, rather than internet overuse, was associated with a higher likelihood of suicide attempts, which highlighted the importance of addressing internet addiction symptoms among Chinese adolescents for suicide prevention.

The relationship between sedentary behavior and non-suicidal self-injury behavior among adolescents in China

Background

The objective of this study was to explore the relationship between sedentary behavior and non-suicidal self-injury (NSSI), and to provide a theoretical basis for preventing and reducing the occurrence of NSSI behavior and the development of intervention measures.

Methods

Between September and December 2021, a sedentary behavior and NSSI survey was administered to 10327 Chinese adolescents aged 12-17 who had been randomly selected using the stratified cluster random sampling method. The results were analyzed using the chi-square test and logistic regression analysis to explore the relationship between sedentary behavior and NSSI in this population.

Results

The study found an overall NSSI detection rate among the participants of 25.1%, with occasional NSSI and frequent NSSI detection rates of 11.0% and 14.1%, respectively. The NSSI detection rate is higher in girls than in boys. After controlling for related influencing factors, the NSSI detection rates among adolescents with sedentary behavior duration ≥8 hours and screen time ≥2 hours were 1.393(β= 0.332, P <0.01) and 1.569(β= 0.451, P <0.01) times higher than those with sedentary behavior duration <8 hours and screen time <2 hours, respectively.

Conclusion

Sedentary behavior, especially that related to screen time is closely related to the occurrence of NSSI in adolescents. To reduce the occurrence of NSSI, we should therefore pay attention to the harmful effects of sedentary behavior on the physical and mental health of teenagers, take corresponding measures to limit sedentary behavior and screen time, and guide teenagers to use electronic devices correctly.

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.

Oppositional defiant disorder, internet gaming disorder, and suicidal ideation among Saudi adolescents: a moderated mediation model of gender and self-control

BACKGROUND

Many psychological changes occur during adolescence, as well as, for some, behavioral disorders. Two such deviant behaviors are internet gaming disorder and oppositional defiant disorder. Prior research has documented the relationships between oppositional defiant disorder and internet gaming addiction with suicidal ideation among adolescents, but none has studied the potential mediating role of self-control nor the moderation role of gender.

OBJECTIVE

This study investigated the relationships between oppositional defiant disorder, internet gaming disorder, and suicidal ideation, and applied a moderated mediation model including the roles of gender and self-control.

METHOD

273 adolescents (mean age = 15.47, 57% females) participated in the study. Respondents completed the Suicidal Ideation Scale; the Internet Gaming Disorder Scale, Short Form; the Oppositional Defiant Scale; and the Self-Control Scale; as well as a set of socio-demographic questions. A moderated mediation model was applied using the PROCESS software package.

RESULTS

Oppositional defiant disorder and internet addiction were positively related with suicidal ideation (β = 0.89, p < 0.001 and β = 0.31, p < 0.001, respectively). Self-control was found to mediate these relationships (βind = 0.10, CI = 0.03 to 0.18 for the oppositional defiant disorder -suicidal ideation relationship) and (βind = 0.19, CI = 0.12 to 0.26 for internet gaming disorder-suicidal ideation relationship). Further, it was found that these relationships were stronger in females compared to males.

CONCLUSIONS

Efforts to reduce suicidal ideation among adolescents with defiant behaviors and gaming disorder should be directed at enhancing their self-control and should be gender mindful.

Relationship Between Loneliness, Hopelessness, Coping Style, and Mobile Phone Addiction Among Non-Suicidal Self-Injury Adolescents

Purpose

This study aims to examine the relationship between loneliness and hopelessness and mobile phone addiction (MPA) in non-suicidal self-injury (NSSI) adolescents, exploring the mediating role of problem-focused and emotion-focused coping.

Methods

This cross-sectional study recruited a total of 1545 NSSI adolescents and 553 non-NSSI adolescents from over 20 specialized psychiatric hospitals across multiple provinces in China. The participants were asked to complete the Beck's Hopelessness Scale, UCLA Loneliness Scale, Coping Style Scale, and Mobile Phone Addiction Index questionnaire. We mainly used the t-tests and structural equation model to analyze the data.

Results

T-tests showed that NSSI adolescents had lower scores on problem-focused coping and higher scores on MPA, loneliness, hopelessness, and emotion-focused coping than non-NSSI adolescents. Structural equation model showed that loneliness and hopelessness were positively related to MPA for non-NSSI adolescents. Hopelessness was positively related to MPA for NSSI adolescents. Emotion-focused coping played a mediating role in the relationship between loneliness/hopelessness and MPA for both NSSI and non-NSSI adolescents.

Conclusion

These findings suggest that NSSI adolescents with loneliness and hopelessness may have mobile phone dependence, highlighting the mediating role of emotion-focused coping style. Such findings help to understand the formation mechanism of MPA for adolescents with NSSI. Alleviating the loneliness and hopelessness and improving adaptive coping styles of adolescents with NSSI have potential implications for reducing their MPA.

Association of screen-based activities and risk of self-harm and suicidal behaviors among young people: A systematic review and meta-analysis of longitudinal studies

Emerging evidence suggests that screen-based activities are associated with self-harm and suicidal behaviors. This study aimed to examine these associations among young people through a meta-analysis. We systematically searched EBSCO pshyARTICLES, MEDLINE (via PubMed), EMBASE, and Web of Science from their inception to April 1, 2022, and updated on May 1, 2024. Longitudinal studies reporting the association between various screen-based activities and subsequent self-harm and suicidal behaviors in young people aged 10 to 24 were included. Nineteen longitudinal studies were included in the qualitative synthesis, and 13 studies comprising 43,489 young people were included in the meta-analysis, revealing that total screen use is significantly associated with the risks of self-harm and suicidal behaviors. Cyberbullying victimization was also related to these adverse outcomes. Subgroup analyses indicated that social media use and problematic screen use are significant risk factors for self-harm and suicidal behaviors. Study quality was appraised using the Newcastle-Ottawa Scale, and potential publication bias was deemed unlikely to affect the results significantly. These findings suggest that screen-based activities should be considered in the management and intervention strategies for self-harm and suicidal behaviors in young people.

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

Background

Non-Suicidal Self-Injury (NSSI) has continued to be a major issue for public health worldwide, especially among teenagers. Studies have found a certain correlation between NSSI and Problematic Internet Use (PIU). However, this relationship is still unclear among Chinese adolescents, a specific population. Hence, a meta-analysis was carried out on observational studies to explore the connection between NSSI and PIU in Chinese teenagers, aiming to provide more clarity on the correlation.

Methods

To identify the link between NSSI and PIU, we scoured seven digital repositories until November 16, 2023. Employing a random-effects meta-analysis framework, we delved into the association between NSSI and PIU. Additionally, we carried out subgroup evaluations to scrutinize variables including geographical location, age demographics, research methodology, diagnostic instruments, gender, and variables controlled for confounding, like symptoms of depression. For amalgamating data, STATA software (version 16) was deployed.

Results

In this analysis, we included 15 research papers encompassing a collective sample of 137,166 individuals. Our findings revealed a significant positive association between NSSI and PIU within the adolescent population in China, with an Odds Ratio (OR) of 2.02 and a 95% Confidence Interval (CI) ranging from 1.73 to 2.37. Notably, this correlation was markedly stronger in specific subgroups: adolescents from China's Western regions exhibited an OR of 4.22 (95% CI: 3.44, 5.18); middle school attendees had an OR of 2.09 (95% CI: 1.92, 2.28); those diagnosed with concurrent depression disorders showed an OR of 2.32 (95% CI: 1.98, 2.73); and female adolescents demonstrated an OR of 2.49 (95% CI: 2.26, 2.75), highlighting the nuanced dynamics of this relationship.

Conclusion

This meta-analysis indicates that PIU among adolescents is associated with an increased risk of NSSI. Our findings underscore the importance of targeting specific populations, including those in the western region of China, middle school students, adolescents with comorbid depression disorders, and female adolescents, who may be at higher risk of PIU and subsequently NSSI. These results emphasize the need for tailored interventions and preventive strategies to address these intertwined issues effectively.

Depression, stress, and anxiety versus internet addiction in early and middle adolescent groups: the mediating roles of family and school environments

BACKGROUND

Family and school environment play a crucial role across the different developmental stages of adolescence. This paper investigates the potential mediating role of family and school environments in the relationship between the three psychosocial predictors of depression, anxiety, stress, and Internet addiction (IA). Specifically, it focuses on the two stages of early and middle adolescence.

METHODS

The study involved a survey of 407 adolescents from Qatar, comprising 250 early adolescents and 157 middle adolescents. Inclusion criteria for the study included adolescents between the ages of 10 to 17 years old, residents of Qatar and studying in a Qatar-based school. To assess the constructs of the three psychosocial predictors, IA, family environment, the study utilized the Depression, Stress, and Anxiety Scale (DASS), the Internet Addiction Diagnostic Questionnaire (IADQ), and the Brief Family Relationship Scale, respectively. School environment was measured using questions from the "Health Behavior in School-aged Children: WHO Collaborative Cross-National survey/study (HBSC) 2013-2014. The study applied standard mediation analysis between the DASS components and IA with family and school environment as the mediators.

RESULTS

Results from the mediation analysis reveal insights into the relationships between psychosocial predictors and IA. The findings indicate that family and school environments partially mediated the relationship with regards to depression, stress, and anxiety in early adolescents. In middle adolescents, family environment partially mediated the relationship with depression and stress and fully mediating the relationship with anxiety. Meanwhile, school environment only exhibited partial mediation in the relationship with anxiety in middle adolescence.

CONCLUSIONS

These results highlight the crucial role parents and schools play in addressing problematic technology usage that develops as a response to depression, anxiety, and stress among adolescents. Moreover, the study reveals nuances in the mediating role of family and school environment in early and middle adolescence. This highlights the evolving nature of these influences across the different stages of development. Notably, this study contributes to the literature by moving beyond the conventional focus on the so-called WEIRD population, and offering valuable insights from a region that is underrepresented in current research.

Examining the relationship between non-suicidal self-harm and suicidality within the past 12-months and gaming problems in Norwegian full-time students

BACKGROUND

Although gaming problems are associated with poor mental health, few population-based studies have examined its association with self-harm and suicidality. This study investigates the association between gaming problems, non-suicidal self-harm and suicidality within the past year, stratified by sex among Norwegian full-time students.

METHODS

Data derived from the Norwegian Students' Health and Wellbeing Study 2022 (N = 59,544). The respondents were categorized into non-gamers, recreational gamers, engaged gamers, problematic gamers, and addicted gamers based on the Game Addiction Scale for Adolescents. Log-link binomial regression models, stratified by sex, adjusted for age, were used to estimate the risk ratio of non-suicidal self-harm (ideation and behavior) and suicidal behaviors (ideation and attempt) across different levels of gaming problems.

RESULTS

Among females, the risk of non-suicidal self-harm and suicidal ideation increased from non-gamer to problem gamer, with no differences between problem and addicted gamers. Among males, the risk of non-suicidal self-harm increased from non-gamers to engaged gamers, but no differences were observed between engaged, problematic, and addicted gamers. No sex × gaming category interaction was observed for suicide attempts. Engaged and addicted gamers had higher risks of suicide attempt than non-gamers and recreational gamers.

CONCLUSIONS

Gaming problems are associated with increased risk of non-suicidal self-harm and suicidal ideation among females. Among males, no differences were observed between engaged, problem and addicted gamers. The results highlight sex when studying health related outcomes and their association to level of gaming problems. Longitudinal studies are warranted to uncover the temporal mechanisms between IGD, non-suicidal self-harm and suicidality.

The relationship between mobile phone addiction and non-suicidal self-injury: Findings from six universities in Shaanxi province, China

BACKGROUND

Although the development and application of mobile phones have changed various aspects of people's lives, excessive use of mobile phones has also raised physical and mental health concerns. However, the relationship between mobile phone addiction (MPA) and non-suicidal self-injury (NSSI) is unclear.

METHODS

A cross-sectional study was conducted (2022) among students from six universities to assess the relationship between MPA and NSSI. A Mobile Phone Addiction Tendency Scale (MPATS) was used to assess MPA, while NSSI was assessed via The Ottawa Self-Injury Inventory. Binary logistic regression models were used to assess the relationship between MPA and NSSI.

RESULTS

A total of 18,723 college students (6531 males [34.9 %] and 12,192 females [65.1 %]) were included in the final analyses. The prevalence of NSSI during the past 12 months was 6.5 %. Furthermore, 5553 participants (29.7 %) met the MPA criteria (MPATS score ≥ 48), and the average MPATS score was 39.5 ± 13.0. MPA was associated with increased odds of NSSI after adjusting for socio-demographic characteristics, health-related characteristics, and relevant psychosocial variables (OR, 1.29; 95 % CI, 1.13-1.46). Moreover, gender did not affect the association of MPA and MPATS score with NSSI (P for interaction>0.05). The restricted cubic splines regression showed that a monotonically increasing risk of NSSI was associated with increasing MPATS score (P for non-linearity = 0.474).

CONCLUSIONS

MPA is associated with increased odds of NSSI among college students, indicating that early examination, prevention, and intervention for MPA may prevent and control NSSI.

Identifying clinical risk factors correlated with addictive features of non-suicidal self-injury among a consecutive psychiatric outpatient sample of adolescents and young adults

Non-suicidal self-injury (NSSI) is an issue primarily of concern in adolescents and young adults. Recent literature suggests that persistent, repetitive, and uncontrollable NSSI can be conceptualized as a behavioral addiction. The study aimed to examine the prevalence of NSSI with addictive features and the association of this prevalence with demographic and clinical variables using a cross-sectional and case-control design. A total of 548 outpatients (12 to 22 years old) meeting the criteria for NSSI disorder of DSM-5 were enrolled and completed clinical interviews by 4 psychiatrists. NSSI with addictive features were determined by using a single-factor structure of addictive features items in the Ottawa self-injury inventory (OSI). Current suicidality, psychiatric diagnosis, the OSI, the revised Chinese Internet Addiction Scale, the Childhood Trauma Questionnaire, and the 20-item Toronto Alexithymia Scale were collected. Binary logistic regression analyses were used to explore associations between risk factors and NSSI with addictive features. This study was conducted from April 2021 to May 2022. The mean age of participants was 15.93 (SD = 2.56) years with 418 females (76.3%), and the prevalence of addictive NSSI was 57.5% (n = 315). Subjects with addictive NSSI had a higher lifetime prevalence of nicotine and alcohol use, a higher prevalence of current internet addiction, suicidality, and alexithymia, and were more likely to have physical abuse/neglect, emotional abuse, and sexual abuse than NSSI subjects without addictive features. Among participants with NSSI, the strongest predictors of addictive features of NSSI were female (OR = 2.405, 95% CI 1.512-3.824, p < 0.0001), alcohol use (OR = 2.179, 95% CI 1.378-3.446, p = 0.001), current suicidality (OR = 3.790, 95% CI 2.351-6.109, p < 0.0001), and psysical abuse in childhood (OR = 2.470, 95% CI 1.653-3.690, p < 0.0001). Nearly 3 out of 5 patients (12-22 years old) with NSSI met the criteria of NSSI with addictive features in this psychiatric outpatients sample. Our study demonstrated the importance of the necessity to regularly assess suicide risk, and alcohol use, as well as focus more on females and subjects who had physical abuse in childhood to prevent addictive NSSI.

Social anxiety and suicidal ideation among middle-school students in China: a mediation model of internet addiction

Background

Suicide is a fatal public health issue for adolescents, and it is of great significance to explore the precursors of suicidal behaviors, especially suicidal ideation. However, the relationship between social anxiety and suicidal ideation and its mechanism are still unclear. The study aims to examine the association between social anxiety and suicidal ideation and the mediating effect through Internet addiction.

Methods

A total of 2,278 middle-school students aged 12 to 16 years were recruited through a multistage cluster sampling method in this cross-sectional study. Logistical regression analysis and structural equation modeling (SEM) were conducted to examine the direct and indirect effects of social anxiety.

Results

During the past year, 262 (11.50%) participants reported suicidal ideation. Females had a higher prevalence of suicidal ideation than males (12.9% vs. 10.0%, p = 0.034), and urban adolescents reported a higher prevalence than their rural counterparts (13.4% vs. 9.6%, p = 0.006). In the total sample, social anxiety and Internet addiction were independently associated with suicidal ideation (p < 0.05). In the subgroup analysis, the association between social anxiety and suicidal ideation was significant only among rural females and urban males (p < 0.05). SEM demonstrated that social anxiety had direct and indirect effects on suicidal ideation, and Internet addiction partially mediated the relationship, with a mediating ratio of 30.53%. The partial mediating effect was also significant only in rural females and urban males.

Conclusion

Adolescents may overuse the Internet to cope with social anxiety and further have suicidal ideation. Limiting Internet use and improving interpersonal skills in real life may be efficient for suicide prevention. In addition, targeted interventions should be tailored by different sexes across urban and rural regions.

Network analysis of suicidality and internet addiction symptoms among Chinese primary and secondary school students

BACKGROUND

The COVID-19 pandemic has increased the risk of both Internet addiction and suicide across various populations, especially among children and adolescents. This study aimed to assess the inter-relationships between Internet addiction symptoms and suicidality among primary and secondary school students from the perspective of network analysis.

METHODS

This was a cross-sectional, multicenter study. The Internet Addiction Test (IAT) was used to assess internet addiction symptoms. Participants were also asked about having any suicidal ideation and suicide plan. Univariate analyses and network analysis were subsequently conducted.

RESULTS

Altogether, 5380 primary and secondary school students participated in the study. Among them, 3161 (58.8 %, 95 % CI = 57.4 %-60.1 %) students reported having Internet addiction symptoms and 798 (14.8 %, 95 % CI = 13.9 %-15.8 %) reported having suicidal ideation or suicide plan in the past two weeks. Network analysis revealed that IAT16 ('Request an extension for longer time spent online'; node strength = 1.223) was the most central symptom in the Suicidality-Internet addiction network model, while the edge suicidality-IAT4 ('Form new relationship with online users'; edge weight = 0.055) was the strongest edge linking both communities.

CONCLUSIONS

Internet addiction symptoms were common among primary and secondary school students during the COVID-19 school closure period in China and were significantly associated with suicidality. Targeted strategies such as strengthening self-control, sense of belonging and connectedness may be important in reducing the risk of both suicidality and Internet addiction among primary and secondary school students.

Suicide and Non-Suicidal Self-Injury From Internet Addiction Among Korean Adolescents

Objectives

This study examined the associations between Internet addiction and suicide and non-suicidal self-injury (NSSI) among South Korean adolescents.

Methods

We conducted a cross-sectional study of 1694 Korean adolescents. The suicidal Ideation Questionnaire and Deliberate Self- Harm Inventories were used to identify high-risk suicide and NSSI groups, respectively. Internet addiction was assessed using the Internet Addiction Scale. Other questionnaires included sociodemographic data, perceived academic stress, and daily life-related factors. We also performed a logistic regression analysis using the high suicide risk and NSSI groups as dependent variables.

Results

The high suicide risk and NSSI prevalence rates among participants were 11.8% and 28.3%, respectively. A multivariable logistic regression analysis revealed that Internet addiction is associated with higher suicide risk and NSSI. Additionally, being female and academic stress were significant suicide risk factors, while male participants had a higher NSSI prevalence.

Conclusion

Our results suggest that monitoring adolescents' Internet use and providing education to prevent Internet addiction would lower high suicide and NSSI risk. Moreover, suicide and NSSI risk screening in adolescents with Internet addiction and providing suitable interventions will be essential for the preventing suicide and NSSI.

The role of depressive symptoms and social support in the association of internet addiction with non-suicidal self-injury among adolescents: a cohort study in China

BACKGROUND

Both internet addiction (IA) and non-suicidal self-injury (NSSI) are major public health concerns among adolescents, however, the association between IA and NSSI was not well understood. We aimed to investigate the association between IA and NSSI within a cohort study, and explore the mediated effect of depressive symptoms and the moderating effect of social support in the association.

METHODS

A total of 1530 adolescents aged 11-14 years who completed both the baseline (T1) and 14-month follow-up (T2) survey of the Chinese Adolescent Health Growth Cohort were included for the current analysis. IA, NSSI, depressive symptoms and social support were measured at T1; depressive symptoms and NSSI were measured again at T2. Structural equation models were employed to estimate the mediated effect of depressive symptoms and the moderating effect of social support in the association between IA and NSSI at T2.

RESULTS

IA was independently associated with an increased risk of NSSI at T2, with the total effect of 0.113 (95%CI 0.055-0.174). Depressive symptoms mediated the association between IA and NSSI at T2, and social support moderated the indirect but not the direct effect of IA on NSSI at T2. Sex differences were found on the mediated effect of depressive symptoms and the moderated mediation effect of social support.

CONCLUSIONS

Interventions that target adolescents' NSSI who also struggle with IA may need to focus on reducing depressive symptoms and elevating social support.

Internet addiction and suicidal behavior among vocational high school students in Hunan Province, China: A moderated mediation model

Background

Vocational education is an important part of high school education in China. However, there is little research on high school students' mental health. This study aimed to investigate the prevalence of suicidal behavior (SB) among this population and the mediating role of insomnia, depression, anxiety, and stress in the relationship between Internet addiction (IA) and SB using a structural equation model.

Methods

A cross-sectional questionnaire survey was conducted among several vocational high school students in Hunan Province, and 7,968 valid questionnaires were obtained. General demographic data and data from the Dual-Mode Self-Control Scale, Athens Insomnia Scale, Depression Anxiety Stress scale-21, and Revised Chen Internet Addiction Scale were collected. A structural equation model was used to explore the different pathways from IA to SB.

Results

Among the participants, 37.7, 15.7, and 21.8% reported suicidal ideation, plans, and attempts, respectively. The structural equation model confirmed that IA was indirectly related to SB and was mediated by insomnia and/or depression, anxiety, and stress.

Limitations

First, we only recruited students from vocational schools in Hunan Province, therefore, the sample may not represent the entire population of vocational students in China. Second, self-report scales were used in this study, and clinical diagnosis required professional interviews. Third, since this study had a cross-sectional design, the causal relationship between the variables could not be determined.

Conclusions

The prevalence of SB among vocational high school students in China was significantly high. The prevention of SB related to IA can be attributed to the improvement of insomnia and emotional problems.

Associations between 24-h Movement Behavior and Internet Addiction in Adolescents: A Cross-Sectional Study

OBJECTIVE

This study aimed to explore the relationship between 24-h activity behavior and Chinese adolescents' Internet addiction.

METHODS

A survey of 2045 adolescents (56.5% boys) was conducted, and adolescents' 24-h movement behavior and Internet addiction were measured via a questionnaire. Descriptive statistics were used to analyze the basic situation of the respondents; chi-square analysis was used to compare gender differences, and logistic regression was used to analyze the relationship between 24-h exercise guide entries and Internet addiction.

RESULTS

From the number of 24-h movement behavior guides, 25.3% of the children did not meet the recommended amount of any kind of activity behavior guide, while 50.4% and 21.7% of the children reached the recommended amount of one and two activity behavior guidelines, respectively; only 3.2% of the children met the recommended amount of all three activity behavior guidelines. Adolescents who did not meet the recommended 24-h activity behavior guidelines were more likely to have Internet addiction (OR = 8.46, 95 CI = 3.06-23.36), and were more likely to have one item (OR = 4.50, 95 CI = 1.64-12.39) or two items (OR = 3.12, 95 CI = 1.11-8.74).

CONCLUSIONS

Physical activity, static behavior, and sleep may all have a greater impact on adolescents' Internet addiction, among which physical activity has a greater impact on adolescents' Internet addiction. Different combinations of 24-h movement behavior have different effects on adolescents' Internet addiction.

Difficulties in impulse control in adolescents with problematic use of the internet and self-injurious behaviors

Problematic use of the internet (PUI) and self-injurious behaviors (SIB) associate in adolescents and both relate to impulsivity. However, studies have not examined whether difficulties in impulse control are shared in adolescents with PUI and SIB, and how PUI relates to SIB frequency and impairment. Here, exploratory factor analysis was performed on a PUI questionnaire based on the Minnesota Impulse Disorder Interview, using survey data from 2,912 Connecticut high-school students. Regression analyses evaluated relationships between PUI factor scores and correlates of SIB. Moderation analyses examined impulsivity and sensation-seeking in relationship to PUI factors and SIB. Two PUI factors were extracted. The first PUI factor was associated with lifetime SIB, frequency, severity, urges, rising tension, and self-perceived problems with SIB. The second factor was associated with lifetime SIB and attempts to reduce SIB. Impulsivity and sensation-seeking associated with PUI factors and SIB, but did not moderate relationships between PUI and SIB. Findings suggest that PUI and SIB are related by difficulties in impulse control, and poor control over internet use is associated with more impairing SIB in adolescents who self-injure. Further research should investigate possible interventions targeting impulsivity and sensation-seeking to prevent PUI and SIB in youth.

Relationship between adverse childhood experiences and problematic internet use among young adults: The role of the feeling of loneliness trajectory

BACKGROUNDS AND AIMS

Given problematic Internet usage's (PIU) negative impact on individual health, this study evaluates how adverse childhood experiences (ACEs) affect young adults' PIU and the possible underlying mechanism of the "feeling of loneliness" (FOL) trajectory.

METHODS

Analyzing a retrospective cohort sample from the Taiwan Youth Project, 2,393 adolescents were interviewed from the average ages of 14-28. We constructed ACE in 2000 using six categories (e.g., abuse and low family socioeconomic status) and 5-item PIU in 2017 from Chen's Internet Addiction Scale. FOL trajectories measured eight times, at average ages 14, 16, 17, 18, 20, 22, 25, 28 years-old.

RESULTS

Overall, 12.65% of the participants did not have ACEs, and 12.78% exhibited PIU. FOL trajectory analyses yielded three groups: "constant low" (reference group: 53.25%); "moderate decline" (36.81%); and "increasing" (9.94%). Regression models showed a dose-response association between ACE and young adults' PIU (adjusted odds ratio = 1.12; 95% confidence interval [CI] = 1.02-1.23) and the two risky loneliness groups (moderate decline: relative risk ratio [RRR] = 1.42, 95% CI = 1.32-1.54; increasing: RRR = 1.52, 95% CI = 1.37-1.71). Structural equation modeling further found that ACEs increase young adults' risk of being in the increasing group, and consequently, the risk of PIU.

DISCUSSION AND CONCLUSIONS

We demonstrated that ACE may be associated with 1) adults' PIU, 2) FOL from adolescence to emerging adulthood, and 3) young adults' PIU through its association with FOL trajectories.

Handwriting and Motor-Related Daily Performance among Adolescents with Dysgraphia and Their Impact on Physical Health-Related Quality of Life

Knowledge is limited about dysgraphia in adolescence and its association with daily motor-related daily performance and health-related quality of life (HRQOL). This study aimed to (1) compare and (2) examine correlations between handwriting measures, motor-related daily performance, and HRQOL of adolescents with and without dysgraphia and (3) examine the contribution of motor-related daily performance and handwriting measures to predict their physical HRQOL. There were eighty adolescents (13-18 yr): half with dysgraphia and half matched controls without dysgraphia per the Handwriting Proficiency Screening Questionnaire and Handwriting Legibility Scale participated. They copied a paragraph script onto a paper attached to the Computerized Penmanship Evaluation Tool digitizer and completed the World Health Organization Quality of Life Questionnaire-brief version and the Adult Developmental Coordination Disorder Checklist (ADC). We found significant between-group differences in motor-related daily performance, handwriting measures, and HRQOL and significant correlations between HRQOL and handwriting process measures and motor-coordination ability. Handwriting measures predicted 25%, and the ADC A and C subscales 45.6%, of the research group's physical QOL domain score variability. Notably, the control group's current perceptions of their motor-coordination performance (ADC-C) predicted 36.5% of the variance in physical QOL. Dysgraphia's negative effects during childhood and adolescence may reduce adolescents' HRQOL now and into adulthood.

Sex differences in association between Internet addiction and aggression among adolescents aged 12 to 18 in mainland of China

BACKGROUND

Previous studies have reported that Internet addiction (IA) is an important predictor of aggression. However, little is known whether aggression is a risk factor of IA. This study aims to explore whether IA can predict total and sub-types of aggression, whether aggression also can predict IA, and the potential sex difference.

METHOD

A total of 15,977 adolescents aged 12 to 18 were recruited though a stratified cluster sampling across five representative provinces in mainland of China. Young's Internet Addiction Test (IAT) and Buss and Warren's Aggression Questionnaire (BWAQ) were used to measure IA and aggression, respectively.

RESULTS

The prevalence of IA and total aggression was 16.8 % and 25.0 %, respectively. Binary logistic regression analysis indicated that IAT score was significantly associated with total and five sub-types of aggression (P < 0.001). However, scores of physical aggression, hostility, and indirect aggression were positively associated with IA (P < 0.001), while verbal aggression and anger were not significant (P > 0.05). Moreover, the interaction of sex and IA was significant for aggression. Specifically, females with IA had higher risks of anger and indirect aggression but had lower risks of physical and verbal aggression compared to males with IA.

LIMITATIONS

Cross-sectional design, self-reported information, and only Chinese rural adolescents.

CONCLUSIONS

IA is a strong risk factor of total and five sub-types of aggression, while not all sub-types of aggression are predictors of IA. Prevention programs for adolescents' IA and aggression should consider different aggression sub-types and sex.

Suicidal behaviours among Ugandan university students: a cross-sectional study

BACKGROUND

Suicide remains the leading cause of death among university students often resulting from multiple physical and psychological challenges. Moreover, suicidal behaviours among students appear to have increased due to the COVID-19 pandemic according to some studies.

OBJECTIVE

To explore the prevalence and associated factors for suicidal ideation, suicide plans, and suicide attempts among university students in Uganda.

METHODS

Cross-sectional study data were collected from May to September 2021 from 540 undergraduate university students in south-western Uganda (363 males, mean age 23.3 years). Questions from the General Health Questionnaire (GHQ-28) were used to assess suicidal ideation, while other bespoke questions were used to assess suicide plans and attempts. The survey also investigated the suicide attempt/plan method, location of the suicidal activity, and reason for not enacting the suicide plan. Three independent regression analyses were used to determine the factors associated with different forms of suicidal behaviours.

RESULTS

The prevalence of past-year suicidal behaviours was 31.85% for suicidal ideation, 8.15% for suicide plans, and 6.11% for suicide attempts. Having a chronic physical medical condition increased the likelihood of having all forms of suicidal behaviours. Suicidal ideation was associated with having difficulty paying university tuition fees. However, being in the fifth year of university education, and feeling satisfied with current academic grades reduced the likelihood of suicidal ideation. Individuals feeling satisfied with academic performance appeared to be a protective factor against having suicide plans. Suicide attempts were associated with having a history of sexual abuse and having difficulty paying university tuition fees. The most common method used for attempted suicide was a drug overdose, and the most common location for attempted suicide was their homes.

CONCLUSION

University students have prevalent suicide behaviours especially among students with a chronic physical medical condition, a history of sexual abuse, and problems paying university tuition fees. Based on the present study, for students at risk, universities should provide appropriate interventions such as life skills education and suicide prevention techniques.

Internet addiction and nonsuicidal self-injury in adolescence: Associations with offline and online social support

OBJECTIVES

Both nonsuicidal self-injury (NSSI) and Internet addiction (IA) are important health issues for adolescents, and social support has been extensively examined as a protective factor for both. This study aims to compare the effect of offline and online social support on IA, and that on NSSI as well.

METHOD

A total of 1911 Chinese adolescents (53.27% females, M_age  = 16.83 ± 0.37) completed self-report questionnaires assessing offline social support, online social support, IA, and NSSI.

RESULTS

The structural equation modeling analysis showed that offline social support was negatively associated with IA and NSSI, while online social support was positively associated with IA and NSSI; IA was positively associated with NSSI. Furthermore, implications for preventions and interventions of IA and NSSI were discussed. The indirect model explained a relatively small variance of NSSI, indicating the possibility of additional factors in the development of NSSI that should be further investigated.

CONCLUSION

This study indicated the differences between offline and online social support, and their different associations with IA and NSSI.

Mediation of Internet addiction on association between childhood maltreatment and suicidal behaviours among Chinese adolescents

Aims

The associations between suicidal behaviours and childhood maltreatment (CM), as well as Internet addiction (IA) have been extensively examined. However, few studies pay attention to different types of CM and all stages of suicidality, including suicidal ideation (SI), suicidal plans (SP) and suicidal attempts (SA). Moreover, little is known regarding the mediation of IA on the relationship between CM and suicidal behaviours. The study aims to explore the direct effect of CM and IA on three stages of suicidal behaviours, and the indirect effect of CM on suicidality via IA.

Methods

A total of 16 130 high-school students aged 12–18 were recruited using a stratified cluster sampling strategy across five representative provinces in China. Relevant information was collected by a self-administered anonymous questionnaire. Multinomial logistic regression analysis and structural equation model were used to examine the associations.

Results

During the last year, 16.0% of participants reported suicidal behaviours. Specifically, 7.9% reported SI only, 4.6% reported SP but no SA, and 3.5% reported SA. The prevalence of neglect, physical abuse and IA in moderate to severe were 28.9, 19.9 and 33.1%, respectively. After controlling for demographic characteristics and confounding factors, such as loneliness, psychological resilience, and social support, moderate and severe neglect, physical abuse and IA were associated with an increased risk of SI, SP and SA (p < 0.01). The total effect of neglect and physical abuse on suicidal behaviours were 0.152 and 0.172, respectively (p < 0.001). The mediation proportion of IA on the association between neglect and suicidal behaviours, as well as physical abuse and suicidal behaviours were 22.4 and 18.0%, respectively.

Conclusions

CM and IA are independently associated with suicidal behaviours among Chinese adolescents. Moreover, IA plays a mediating role on the relationship between CM and suicidality. Targeted interventions for adolescents’ suicidal behaviours should focus on those who have experience of CM and IA.

A Latent Profile Analysis of Problematic Media Device Use and Its Association With Executive Function and Behavioral Problem Among Children: A Population-Based Study

OBJECTIVE

Despite the rapid increase in problematic media device use, relatively little is known about specific characteristics and extent of problematic media device and how they relate to different psychological features.

METHODS

Data extracted from the Panel Korea Study for the Child Cohort Study were used. At the age of 9 years, media device addiction severity was assessed using the K-scale, and children's behavioral outcomes were assessed using the Child Behavior Checklist. Among children with problematic media device use (n=339), we performed latent profile analysis using the K-scale to identify subtypes of problematic media device use, and then compared the child behavioral problems and executive function according to the different subtypes of problematic media device use.

RESULTS

Children with problematic media device use were divided into class 1 (n=51), class 2 (n=138), and class 3 (n=150). Compared with classes 2 and 3, class 1 had more severe problematic media device use, including daily activity disturbance, withdrawal, and tolerance. Class 1 had the most serious behavioral problems and executive function difficulties among classes. Class 2 had greater daily activity disturbance and tolerance than those of class 3, but executive function showed no significant difference between the two classes. In logistic regression analysis, behavioral problems except for somatization were more common in class 1 than in the control group.

CONCLUSION

Results suggest that problematic media device use is associated with significant behavioral problem and executive function difficulties and underscore the need for further clinical and research attention for these specific subgroup members.

Internet addiction and affected factors in primary school students: School-based study

The aim of the study was to determine the prevelance of internet addiction and effected factors in primary school students. This school-based study was a cross-sectional descriptive research design. This study was conducted with 277 students. Prevelans of IA among students was found 10.5%. Variables such as age (≥11 years), internet use in a day (≥3 h), not use internet for education, homework, research, use internet for communication, social network, gaming and mid academic grade accounted for 23% of the internet addiction. It is recommended that children with risk factors for internet addiction should be determined in the early stages, and that school-based intervention programs should be performed for students and their parents to prevent internet addiction.

The Relationship between Internet Use and Health among Older Adults in China: The Mediating Role of Social Capital

A growing academic attention has been paid to the health effects of Internet use among older adults. However, the relationship between Internet use and health among older adults in China remains to be studied further. On the one hand, existing research is still controversial on this issue. On the other hand, the underlying mechanism of how Internet use affects the health of older adults has not been fully explored. This article examined the relationship between Internet use and health among older adults with the mediating role of social capital in China based on the 2018 wave of China Health and Retirement Longitudinal Study (CHARLS). This study reveals that Internet use has a positive association with the health of older adults, and the positive effects of internet use among older adults are heterogeneous in age and residential location. In addition, this study also demonstrates that social capital plays a partial mediating role between Internet use and physical health among older adults. It is important for the government to take effective measures to expand Internet use and enhance social capital among older adults.

C. S, Shrestha S, Thapa DK. Internet addiction and sleep quality among adolescents in a peri-urban setting in Nepal: A cross-sectional school-based survey

Background

Excessive use of the internet among adolescents often led to later bedtimes and poor sleep quality. This study assessed the relationship between internet addiction and sleep quality among adolescents in a peri-urban setting in Nepal.

Method

This cross-sectional study employed a questionnaire survey among 390 adolescent students recruited from two schools in Kirtipur Municipality in Nepal. The Internet Addiction Test and the Pittsburgh Sleep Quality Index were used to assess internet addiction and poor sleep quality respectively. The association between internet addiction and sleep quality was analysed by logistic regression.

Results

One-fifth (21.5%) of the participants were identified with borderline internet addiction and 13.3% with possible internet addiction. Poor sleep quality was found among 31% of the participants. Internet addiction was significantly associated with poor sleep quality (OR = 1.85, p = 0.022 for borderline, and OR = 3.98, p = <0.001 for possible internet addiction compared to no internet addiction).

Conclusion

Adolescents with internet addiction were more vulnerable to suffer from poor sleep quality. It is recommended that municipalities and schools should aware the adolescent students on the adverse effects of excessive internet use including poor sleep quality. The findings have implications for adolescents, parents, school authorities and researchers.

Examining the Relationship Between the Use of a Mobile Peer-Support App and Self-Injury Outcomes: Longitudinal Mixed Methods Study

BACKGROUND

Many individuals who self-injure seek support and information through online communities and mobile peer-support apps. Although researchers have identified risks and benefits of participation, empirical work linking participation in these web-based spaces to self-injury behaviors and thoughts is limited.

OBJECTIVE

This study aims to investigate the relationship between behavioral and linguistic traces on a mobile peer support app and self-injury outcomes.

METHODS

Natural use data and web-based surveys (N=697) assessing self-injury outcomes were collected from 268 users (aged 13-38 years; median 19; 149/268, 55.6% female) of a mobile peer-support app for 4 months. Participants were identified as having posted self-injury content using an internal classifier. Natural log data was used to predict self-injury outcomes in a series of multilevel logistic and linear regressions.

RESULTS

Greater engagement on a mobile peer-support app was associated with a decreased likelihood of self-injury thoughts (odds ratio [OR] 0.25, 95% CI 0.09-0.73) and fewer intentions to self-injure (b=-0.37, SE 0.09), whereas posting triggering content was associated with an increased likelihood of engaging in behaviors (OR 5.37, 95% CI 1.25-23.05) and having self-injury thoughts (OR 17.87, 95% CI 1.64-194.15). Moreover, viewing triggering content was related to both a greater ability to resist (b=1.39, SE 0.66) and a greater intention to self-injure (b=1.50, SE 0.06).

CONCLUSIONS

To our knowledge, this is the first study to connect naturally occurring log data to survey data assessing self-injury outcomes over time. This work provides empirical support for the relationship between participation in online forums and self-injury outcomes, and it articulates mechanisms contributing to this relationship.

Internet Addiction and Attention in Adolescents: A Systematic Review

Internet addiction (IA) has been explored worldwide and involves some features that might harm social, psychological, and functional aspects. The vulnerability of adolescents might result in some addictive behaviors, and the Internet is one of them. The aim of this systematic review was to identify empirical studies that have been done to explore instruments that have been used to assess IA and to verify what variables and comorbidities are related to IA in adolescents, including executive functions, such as attention. To accomplish our aim, a systematic search was conducted in the following databases: PubMed, Web of Science, and PsycINFO. Some inclusion and exclusion criteria were used to select the studies and 44 in total were analyzed independently. The results showed that the most used instrument to assess IA is the Young's Internet Addiction Test. A few studies have been developed in the Western world, and most of them have analyzed attention bias in attention-deficit/hyperactivity disorder (ADHD) and non-ADHD groups. Furthermore, other variables have been widely explored in the studies, such as depression, sleeping patterns, body weight, aggressiveness, and other addictive substances.

Prevalence and Predisposing Factors of Suicidal Ideation Among the University Students in Bangladesh: A Single-Site Survey

Recently, suicide among Bangladeshi university students has become a serious problem. However, to date, there have been no studies assessing suicidal behaviors among Bangladeshi students. Therefore, the present study investigated suicidal ideation (SI) and its risk factors among this population. A classroom-based convenience sampling method was utilized to survey 665 students of a university in Bangladesh (67.5% males; aged 21.16 years: SD ± 1.6). In addition to socio-demographic questions, the survey also included the Smartphone Application-Based Addiction Scale, Bergen Facebook Addiction Scale, and Depression Anxiety Stress Scale–21. Results showed that the prevalence of suicidal ideation was 2.3% in the past 24 h, 4.8% in the past 15 days, 6.9% in the past month, 14.7% in the past year, and 61.1% in the lifetime. The unadjusted regression model showed that being divorced (or separated) from a partner (OR = 4.486, 95% CI = 1.972–10.207, p < 0.0001), Facebook addiction (OR = 1.550, 95% CI = 1.006–2.388, p = 0.047), depression (OR = 1.657, 95% CI = 1.677–4.211, p < 0.0001), anxiety (OR = 2.649, 95% CI = 1.624–4.320, p < 0.0001), and stress (OR = 2.626, 95% CI = 1.673–4.122, p < 0.0001) were the risk factors of past-year SI. Compared with global prevalence rates, the present study reported higher levels of SI prevalence. Therefore, supportive suicide prevention programs are needed to tackle SI and alongside comorbid psychopathology.

Serial multiple mediation of the association between internet gaming disorder and suicidal ideation by insomnia and depression in adolescents in Shanghai, China

BACKGROUND

High prevalence and strong relationships among suicidal ideation, Internet gaming disorder (IGD), insomnia, and depression have been reported for adolescents worldwide, but the mechanism underlying these psychological problems remains unclear. This cross-sectional study explored the mediating effect of insomnia and depression on the association between IGD and suicidal ideation.

METHODS

Participants were 1066 adolescents (median age = 13.0 years) with Internet games exposure in the previous 12 months from junior high schools in Shanghai, China. Questionnaire measures of suicidal ideation, IGD, insomnia, depressive symptoms, and background characteristics were obtained. Path analysis was conducted to test the multiple mediating roles of insomnia and depression.

RESULTS

Suicidal ideation, IGD, insomnia, and depression prevalence was 27.2, 13.6, 9.2, and 17.0%, respectively. A serial multiple mediation model was generated. The mediation effect of insomnia and depression on the pathway from IGD to suicidal ideation was 45.5% (direct effect: standardized estimate [Std. estimate] = 0.186; total indirect effect: Std. estimate = 0.155). The association between IGD and depression was partially mediated by insomnia (direct effect: Std. estimate = 0.211; indirect effect: Std. estimate = 0.135). The proposed model fit the data well.

CONCLUSIONS

Insomnia and depression may serially mediate the association between IGD and suicidal ideation. IGD was positively associated with insomnia, then with depression, which in turn positively contributed to suicidal ideation. We suggest greater monitoring of Internet use and prevention of insomnia and depression to mitigate the risk of suicidal ideation among Chinese adolescents.

Systematic review and meta-analysis of epidemiology of internet addiction

BACKGROUND

The field of internet addiction has experienced significant debates on conflicting epidemiology. This meta-analysis investigated the prevalence rates of generalized internet addiction (GIA) and internet gaming disorder (IGD).

METHODS

We included 113 epidemiologic studies covering 693,306 subjects published from 1996 to 2018 (for 31 nations) that reported prevalence rates for GIA or IGD. We examined pooled prevalence of GIA and IGD and the hypothesized moderators including year, geographic regions, types of scales, and sample representativeness.

RESULTS

All 133 effect sizes included 53,184 subjects with GIA or IGD. Weighted average prevalence for GIA and IGD were 7.02 % (95 % CI, 6.09 %-8.08 %) and 2.47 % (95 % CI, 1.46 %-4.16 %) respectively. For GIA, prevalence was increased over time and prevalence rates variated among different scales. IGD prevalence was neither moderated by year, regions, nor sample representativeness.

CONCLUSIONS

The prevalence of GIA was higher than the prevalence of IGD. The GIA prevalence was increasing over time and variated with different assessments. Our results reveal that GIA may reflect a pattern of increasing human-machine interaction.

Problematic Internet use and the risk of suicide ideation in Chinese adolescents: A cross-sectional analysis

To evaluate the relationships between problematic Internet use (PIU) and suicidal ideation (SI) among adolescents, we encompassed 12,507 participants (16.6 ± 0.8 years). The occurrence of mood disorders, quality of life (QOL), personality traits and SI were compared in adolescents with and without PIU. Multilevel logistic regression models, trend analysis and interaction analysis were employed. A total of 2,809 (22.46%) adolescents reported SI. PIU was assessed using Internet Addiction Test score (IATs), and 3,442 (27.52%) participants met the criteria for PIU (IATs ≥ 40). PIU was significantly and independently associated with SI [AOR for suicidal ideation (vs. IATs < 40): 1.00 for 40-59 points; 1.3 (CI, 1.2-1.5): 60-79 points; 1.7 (CI, 1.4-2.1): 80-100 points; and 2.2 (CI, 1.2-3.9)]. Trend analysis demonstrated that PIU increased the risk of SI in each of the subgroups (p for trend ≤ 0.001 for each). Interaction analysis showed an association of PIU and SI that were dependent on mood disorders, QOL, impulsivity and aggression (p-value for interaction < 0.05). These findings highlight the need for a range of cross disciplinary health interventions to afflicted families, students, and clinicians, to increase the awareness of adverse PIU effects.

Internet addiction among college students in a Chinese population: Prevalence, correlates, and its relationship with suicide attempts

BACKGROUND

Internet addiction is common, but its relationship with suicide attempts is rarely reported among Chinese college students. This study aimed to investigate the prevalence and correlates of internet addiction among Chinese college students.

METHODS

A cross-sectional study was conducted among 8,098 college students in Hunan province, China. We collected the following data: demographic variables, suicidal behaviors, internet addiction (Revised Chinese Internet Addiction Scale), depression (Self-reporting Depression Scale), and anxiety (Self-Rating Anxiety Scale).

RESULTS

The prevalence of internet addiction was 7.7% in these Chinese college students. Logistic regression analysis showed that good relationship with mother (1.730 [1.075, 2.784]), good relationship with father (0.615 [0.427, 0.885]), family history of mental disorders (2.291 [1.122, 4.676]), anxiety (1.987 [1.382, 2.857]), depression (2.016 [1.384, 2.937]), suicidal ideation (2.266 [1.844, 2.784]), and suicide attempts (1.672 [1.258, 2.224]) were independent correlates for internet addiction, the adjusted R square for this model is 13.7%. Furthermore, the prevalence of suicide attempts among internet addiction participants was 21.4%, and anxiety (3.397 [1.058, 10.901]), suicidal ideation (26.984 [11.538, 63.112]), and suicide plans (8.237 [3.888, 17.451]) were the independent predictors for suicide attempts, the adjusted R square for this model is 51.6%.

CONCLUSION

Our results show that internet addiction is common among Chinese college students. In addition, suicide attempts are very common among internet addicts, suggesting that special measures and attention should be provided to these students according to risk factors to prevent their suicidal behavior.

Suicidal ideation among Lebanese adolescents: scale validation, prevalence and correlates

BACKGROUND

In addition to the unstable political situation, Lebanon had experienced a cycle of wars, local armed conflicts, terrorist attacks, and crises (lack of clean water, recurrent power failure, and waste mismanagement, in addition to the growing number of unemployed people, as the number of Syrian refugees has dramatically increased, and led to competition for jobs with locals. All these factors make the Lebanese population prone to mental disorders, particularly suicide, without clear management policies. This study aims to validate the Columbia-Suicide Severity Rating Scale (CSSRS), and determine the prevalence of suicidal ideation and associated factors among a Lebanese nationally representative sample of adolescents from 9th to 12th grades.

METHODS

Participants were 1810 adolescents who enrolled in this cross-sectional study (January-May 2019), using a proportionate random sample of schools from all Lebanese Mohafazat. The Columbia-Suicide Severity Rating Scale was used to screen for suicidal ideation.

RESULTS

The results showed that 28.9% had some type of suicidal ideation [95% CI 26.7-31.1%]. The CSSRS items converged on a one-factor solution, accounting for a total of 85.40% of the variance (αCronbach = 0.966). Higher psychological abuse (Beta = 0.041), child physical abuse (Beta = 0.030), alcohol dependence (Beta = 0.062), social fear (Beta = 0.028), victimization/bullying score (Beta = 0.028), impulsivity (Beta = 0.028) and internet addiction (Beta = 0.010) scores were significantly associated with higher suicidal ideation. Same applies to adolescents whose parents are separated compared to living together (Beta = 0.992) and in females compared to males (0.311). On another hand, a higher age (Beta = - 0.182) was significantly associated with lower suicidal ideation.

CONCLUSION

This study provides insights about suicidal ideation among Lebanese adolescents and related risk factors, such as child psychological and physical abuse, alcohol use disorders, social fear, bullying and victimization, impulsivity, and internet addiction.

Association of Internet Addiction With Nonsuicidal Self-injury Among Adolescents in China

IMPORTANCE

Both nonsuicidal self-injury (NSSI), defined as the direct, deliberate damage of one's body tissue without suicidal intent, and internet addiction among adolescents are public health concerns. However, the possible association of NSSI with internet addiction is not well understood.

OBJECTIVE

To examine the occurrence of internet addiction with NSSI and any sex differences among Chinese adolescents.

DESIGN, SETTING, AND PARTICIPANTS

A multicenter, cross-sectional, survey study was conducted from February 18 to October 15, 2015, among adolescents aged 11 to 20 years from 343 classes in 45 public high schools across 5 provinces of China. Data analysis was performed from August 1, 2018, to March 1, 2019.

EXPOSURES

Possible internet addiction and internet addiction.

MAIN OUTCOMES AND MEASURES

Less-frequent (1-4 times) NSSI and more-frequent (≥5 times) NSSI were surveyed using the Chinese version of the Functional Assessment of Self-Mutilation.

RESULTS

A total of 15 623 students (8043 male [51.5%] and 7580 female [48.5%]) aged 11 to 20 years (mean [SD] age, 15.1 [1.8] years) participated. Of these, 4670 participants (29.9%) met the criteria for possible internet addiction and 509 participants (3.3%) met the criteria for internet addiction. A total of 2667 students (17.1%) engaged in less-frequent NSSI, while 1798 students (11.5%) engaged in more-frequent NSSI in the 12 months preceding the survey. Both possible internet addiction and internet addiction were associated with less-frequent or more-frequent NSSI. The adjusted odds ratios were 1.29 (95% CI, 1.17-1.42) for possible internet addiction and 1.41 (95% CI, 1.11-1.80) for internet addiction for less-frequent NSSI; for more-frequent NSSI, the adjusted odds ratios were 1.75 (95% CI, 1.56-1.96) for possible internet addiction and 2.66 (95% CI, 2.10-3.38) for internet addiction. These associations were similarly observed among age groups of 11 to 14, 15 to 17, and 18 to 20 years. No sex disparities were found in the associations of internet addiction with NSSI, except among adolescents aged 11 to 14 years, where the odds ratios for possible internet addiction with less-frequent NSSI were higher in male adolescents (1.53; 95% CI, 1.25-1.88) than female adolescents (1.13; 95% CI, 0.90-1.47).

CONCLUSION AND RELEVANCE

Internet addiction appears to be associated with NSSI, and the findings of this study suggest that the association was similar between male adolescents and female adolescents. These data suggest that evaluation of the risk of NSSI for adolescents in association with internet addiction may help health care professionals in developing preventive interventions for NSSI.

The Current Situation of Internet Addiction and Its Impact on Sleep Quality and Self-Injury Behavior in Chinese Medical Students

OBJECTIVE

The purpose of this cross-sectional survey is to explore the current state of Internet addiction (IA) in Chinese medical students and its connection with medical students' sleep quality and self-injury behavior.

METHODS

Respondents were came from Wannan Medical College, China. The Young's Internet Addiction Test, Pittsburgh Sleep Quality Index (PSQI), Self-Harm Questionnaire were used in this cross-sectional survey. A total of 3,738 medical students were investigated, 1,552 (41.52%) males, 2,186 (58.48%) females. T-test, chi-square test and MANOVA were used for data analysis.

RESULTS

Of the 3,738 medical students, 1,054 (28.2%) reported having IA, 1,126 (30.1%) reported having poor sleep quality, 563 (15.1%) having self-harm behaviors. IA tends to be more female, upper grade students. The sleep quality of IA was worse than that of non-IA (χ2=54.882, p<0.001), and the possibility of self-injury was higher than non-IA (χ2=107.990, p<0.001).

CONCLUSION

This survey shows that the IA detection rate of medical students was 28.2%. Females, higher grade students had a higher IA detection rate. The low sleep quality and self-injury behavior of medical students are associated with IA.

When adolescents face both Internet addiction and mood symptoms: A cross-sectional study of comorbidity and its predictors

This study aimed to determine the prevalence of comorbid Internet addiction (IA) and mood symptoms and to identify common and unique risk profiles for individual and comorbid mental health problems among adolescents. A total of 2272 high school students in Changchun, China, were included in a cross-sectional study. Participants were asked to complete paper-based questionnaires on sociodemographic characteristics, lifestyle factors, Internet use, parent-child relationships, IA, and mood symptoms. Multivariate logistic regressions were used to compare the risk profiles for IA, mood symptoms, and their comorbidity. The Bonferroni correction was used for multiple tests. Students who were girls, were current smokers, had more than 1.5 h sleep deprivation per day on weekdays, used the Internet for more than 30 and 240 min per day on weekdays and weekends, respectively, used social networking sites more than 6 times per day, were Internet gamers, and/or reported poor parent-child relationships reported higher rates of comorbid IA and mood symptoms. Adolescents exposed to more of these correlates would have a higher risk of IA, mood symptoms, and their comorbidity. Public strategies for the prevention of mental illnesses should expand their capacity to identify and limit the co-occurrence of IA and mood symptoms.

Association between problematic Internet use, sleep disturbance, and suicidal behavior in Chinese adolescents

BACKGROUND AND AIMS

This large-scale study aimed to test (a) associations of problematic Internet use (PIU) and sleep disturbance with suicidal ideation and suicide attempts among Chinese adolescents and (b) whether sleep disturbance mediates the association between PIU and suicidal behavior.

METHODS

Data were drawn from the 2017 National School-based Chinese Adolescents Health Survey. A total of 20,895 students' questionnaires were qualified for analysis. The Young's Internet Addiction Test was used to assess PIU, and level of sleep disturbance was measured by the Pittsburgh Sleep Quality Index. Multilevel logistic regression models and path models were utilized in analyses.

RESULTS

Of the total sample, 2,864 (13.7%) reported having suicidal ideation, and 537 (2.6%) reported having suicide attempts. After adjusting for control variables and sleep disturbance, PIU was associated with an increased risk of suicidal ideation (AOR = 1.04, 95% CI = 1.03-1.04) and suicide attempts (AOR = 1.03, 95% CI = 1.02-1.04). Findings of the path models showed that the standardized indirect effects of PIU on suicidal ideation (standardized β estimate = 0.092, 95% CI = 0.082-0.102) and on suicide attempts (standardized β estimate = 0.082, 95% CI = 0.068-0.096) through sleep disturbance were significant. Conversely, sleep disturbance significantly mediated the association of suicidal behavior on PIU.

DISCUSSION AND CONCLUSIONS

There may be a complex transactional association between PIU, sleep disturbance, and suicidal behavior. The estimates of the mediator role of sleep disturbance provide evidence for the current understanding of the mechanism of the association between PIU and suicidal behavior. Possible concomitant treatment services for PIU, sleep disturbance, and suicidal behavior were recommended.
