Factors associated with severity, incidence or persistence of internet gaming disorder in children and adolescents: a 2-year longitudinal study

Gender-specific motivational pathways in ADHD-related inattention and gaming disorder symptoms

Comorbidity between attention-deficit/hyperactivity disorder (ADHD) and gaming disorder (GD) is widely recognized in the literature. Previous research has indicated gender-dependent underlying mechanisms in the development and maintenance of problematic gaming. Motivational research presents an opportunity to provide further insight regarding the nature of this association. Self-report data were collected from videogame players (N = 14,740) using an online survey in collaboration with a popular gaming magazine. The survey included items concerning symptoms of ADHD and GD, motives for gaming, and time spent playing videogames. Structural equation modeling was used to create two parallel mediation models (one for males, one for females), including motives to play games as mediators. This was done to potentially explain psychological drivers of the association between ADHD and GD. Results demonstrated a common pathway from inattention to GD symptom severity through the immersion/escapism motivation for both males (β = 0.068; p < 0.001) and females (β = 0.081; p < 0.05), while the paths from inattention to GD symptom severity through the habit/boredom motive (β = 0.094; p < 0.001) and competition motive (β = 0.021; p < 0.001) were only significant for males. Gamers experiencing symptoms of ADHD, especially inattentive symptoms, are at risk of the occurrence of GD symptoms through videogames becoming a source of maladaptive coping with daily psychological disturbances. Males experiencing inattentive symptoms tend to additionally develop problematic patterns of use through videogame playing, becoming a subjectively meaningless and boredom-reduction-oriented habitual activity or a platform of virtual competition. Unique differences suggest the necessity of different treatment approaches for males and females.

Recurrence of internet gaming disorder in Korean adolescents: a 24-month follow-up study

Many adolescents use internet games, and some of them experience psychological and social difficulties due to excessive gaming. Although there have been many studies on the onset and associated factors of internet gaming disorder (IGD) , research focusing specifically on its relapse is scarce. Considering that addictive disorders often have a chronic course with frequent relapse, this study prospectively observed adolescents from the general population to explore IGD recurrence rate and associated factors of recurrence. In this prospective cohort study, from 1587 middle school gaming users, 1452 (91.5%) were followed up at 12 months and 24 months. The results showed that the cumulative recurrence rate of IGD was 16.1%, which was higher than the initial incidence rate of 3.6%; the adjusted incidence rate ratio was 2.43 with 95% CI 1.21-4.87 (P = 0.012). In addition, starting internet gaming before entering primary school was associated with a higher risk of relapse (P = 0.004). Limiting internet gaming for children before they enter primary school may reduce the risk of relapse of IGD that they may encounter during their adolescent years.

Problematic gaming, psychiatric comorbidities, and adolescence: A systematic review of the literature

Problematic gaming is particularly prevalent in adolescent and young adult populations. While numerous studies have investigated the psychiatric comorbidities of Internet Gaming Disorder in young adults, few have focused specifically on adolescents who might be especially at risk because developmental particularities related to this developmental period. Here, we conducted a review of the literature, in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, in order to highlight the types of psychiatric comorbidities found in adolescents with problematic gaming.. We selected and analyzed 30 cross-sectional and longitudinal studies which correspond to 3683 adolescents (63,27% of boys) worldwide with problematic gaming. Our results highlight the high prevalence of Attention Deficit Hyperactivity Disorder (ADHD) in adolescents with problematic gaming and the links between this addiction and inattention, anxiety, depression, behavioural and emotional problems. These psychiatric comorbidities interact with problematic gaming and predict it throughout the adolescent's development. Moreover, this interaction involves personality profile and environment, including parental education. The complexity of this interaction argues in favor of the multi-level assessment that we are promoting.

Investigating the mechanisms of internet gaming disorder and developing intelligent monitoring models using artificial intelligence technologies: protocol of a prospective cohort

BACKGROUND

Internet gaming disorder (IGD), recognized by the World Health Organization (WHO), significantly impacts adolescent mental and physical health. With a global prevalence of 3.05%, rates are higher in Asia, especially among adolescents and males. The COVID-19 pandemic has exacerbated IGD due to increased gaming time from isolation and anxiety. Vulnerable groups include adolescents with poor academic performance, introverted personalities, and comorbid mental disorders. IGD mechanisms remain unclear, lacking prospective research. Based on Skinner's reinforcement theory, the purpose of this study is to explore the mechanisms of IGD from individual and environmental perspectives, incorporating age-related changes and game features, and to develop intelligent monitoring models for early intervention in high-risk adolescents.

METHODS

This prospective cohort study will investigate IGD mechanisms in middle and high school students in Shenzhen, China. Data will be collected via online surveys and Python-based web scraping, with a 3-year follow-up and assessments every 6 months. Unstructured data obtained through Python-based web scraping will be structured using natural language processing techniques. Collected data will include personal characteristics, gaming usage, academic experiences, and psycho-behavioral-social factors. Baseline data will train and test predictive models, while follow-up data will validate them. Data preprocessing, normalization, and analysis will be performed. Predictive models, including Cox proportional hazards and Weibull regression, will be evaluated through cross-validation, confusion matrix, receiver operating characteristic (ROC) curve, area under the curve (AUC), and root mean square error (RMSE).

DISCUSSION

The study aims to understand the interplay between individual and environmental factors in IGD, incorporating age-related changes and game features. Active monitoring and early intervention are critical for preventing IGD. Despite limitations in geographic scope and biological data collection, the study's innovative design and methodologies offer valuable contributions to public health, promoting effective interventions for high-risk individuals.

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.

Screen time and addictive use of gaming and social media in relation to health outcomes

Introduction

This study examined associations between screen time and addictive use (i.e., heavy involvement and negative consequences) of gaming and social media, and their independent effects on health outcomes.

Methods

Survey data were collected from 2,265 participants (mean age = 21.57). Internet Gaming Disorder (IGD) and Social Media Disorder (SMD) were measured with the Gaming and Social Media Questionnaire (GSMQ-9), with separate measures for heavy involvement and negative consequences. Screen time was measured by weekly hours of gaming and social media. Assessed health outcomes were psychological problems, low self-concept, social problems, sleep problems, and sleep time.

Results

Screen time and addictive use were significantly associated for both gaming and social media, with associations being stronger for symptoms of heavy involvement compared to symptoms of negative consequences. However, despite significant associations, a substantial proportion of the participants with a high screen time did not meet any or just one symptom of addiction. More importantly, it was primarily negative consequences that had independent effects on health outcomes, except for sleep. High levels of heavy involvement in gaming, were even related to lower, not higher, levels of psychological problems.

Conclusion

The present findings study show that screen time is a poor indicator of addictive use of gaming and social media. Given that it was primarily negative consequences of gaming or social media that had effects on health outcomes, our study also emphasizes the need to distinguish between different types of addictive use and to further examine the diagnostic validity of the nine IGD symptom criteria.

Association between gaming disorder and regional homogeneity in highly involved male adult gamers: A pilot resting-state fMRI study

BACKGROUND

Gaming behavior can induce cerebral changes that may be related to the neurobiological features of gaming disorder (GD). Additionally, individuals with higher levels of depression or impulsivity are more likely to experience GD. Therefore, the present pilot study explored potential neurobiological correlates of GD in the context of depression and impulsivity, after accounting for video gaming behavior.

METHODS

Using resting-state functional magnetic resonance imaging (fMRI), a cross-sectional study was conducted with 35 highly involved male adult gamers to examine potential associations between GD severity and regional homogeneity (ReHo) in the entire brain. A mediation model was used to test the role of ReHo in the possible links between depression/impulsivity and GD severity.

RESULTS

Individuals with greater GD severity showed increased ReHo in the right Heschl's gyrus and decreased ReHo in the right hippocampus (rHip). Furthermore, depression and impulsivity were negatively correlated with ReHo in the rHip, respectively. More importantly, ReHo in the rHip was found to mediate the associations between depression/impulsivity and GD.

CONCLUSIONS

These preliminary findings suggest that GD severity is related to ReHo in brain regions associated with learning/memory/mood and auditory function. Higher levels of depression or impulsivity may potentiate GD through the functional activity of the hippocampus. Our findings advance our understanding of the neurobiological differences behind GD symptoms in highly involved gamers.

Social media use and paediatric practice: Hippocratic help, hype or harm?

Social media is increasingly a part of our personal and professional life and is here to stay. Here, I reflect on issues surrounding the use of social media (SMU) in the digital health context by clinicians in Australian paediatric health care. I aim to briefly highlight some inherent multifactorial and contextual ethical considerations which mainly relate to professionalism; including boundaries, obligations to patients and families within the therapeutic alliance, and balancing the help, hype and harm of SMU in clinical practice. I conclude that digital health and SMU are ubiquitous, and can be beneficial if used circumspectly with Hippocratic principles that have been updated for the modern era and are grounded in ancient moral codes. Unfettered SMU however, without adherence to ethical and legal guidelines is problematic, and may expose patients, families and clinicians to significant risk of harm and moral vulnerability. Justifiable, explicit, consistent and regularly reviewed boundaries, both professional and personal, are ethically advisable. These should reflect, and adapt to, the rapidly evolving nature of social media as imprudent digital health and SMU without proportionate limits, may undermine still relevant Hippocratic tenets, and the primacy of doing no harm.

How general functioning of family affects gambling-related beliefs: the mediating role of communication and the moderating role of impulsivity trait

Background

Gambling behaviors can be exhibited by individuals raised in families with impaired parent-child communication and individuals with more impulsive traits. However, it remains unclear how gambling-related beliefs are modulated by impulsivity traits and parent-child communication styles.

Methods

A total of 95 adult patients (age ≥ 18 years) diagnosed via DSM-5 criteria with gambling disorder (GD) completed our questionnaire. Participants filled out pen-and-paper questionnaires that included basic demographic information, the Family Assessment Device (FAD), Parent-Adolescent Communication Scale (PACS), Gambling Attitude and Belief Survey (GABS), and Barratt Impulsiveness Scale (BIS). We used a moderation mediation model to explore the relationship between variables. The study results were considered statistically significant if p < 0.05, or the 95% confidence interval did not contain zero.

Results

The scores of the problems in communication with mother subscale (PCMS) of PACS were significantly positively correlated with the scores of GABS and the general functioning 12-item subscale (GF12) of FAD. The relationship between the scores of GF12 and GABS was completely mediated [β = 4.83, (1.12, 10.02)] by PCMS scores, and the BIS scores moderated this relationship: the predictive path between GF12 and PCMS scores [index of moderated was β = -0.25, (-0.60, -0.04)], and the indirect predictive front path between the scores of GF12 and GABS were significant only in subjects with low BIS scores.

Conclusion

These findings suggest that poor general functioning of the family may increase gambling-related beliefs as a result of communication problems with mothers, and this result is only significant for individuals with low impulsivity. When treating patients with GD, more treatment of mother-child communication issues and individual impulsivity may be more conducive to their recovery.

High-Risk Gaming Is Associated with Frequent Substance Use: An Exploratory Survey among Young Adults

INTRODUCTION

Internet gaming disorder (IGD) is an emerging condition within the field of behavioural addictions. IGD has been demonstrated to be highly comorbid with many other mental health disorders. Among these, substance use has been associated with IGD, and there are underlying similarities between behavioural addictions and substance use disorders. The main aims of the present study were (i) to investigate the association between high-risk gaming and substance use among young adults drawn from the general Italian population; and (ii) to explore the psychopathological correlates of high-risk gaming.

METHODS

Lifetime substance use, type of substances consumed, and frequency of use were investigated through an online survey in a sample of 913 adults aged 18-40 years. High-risk gaming was assessed using the ten-item Internet Gaming Disorder Test (IGDT-10). Psychopathology was assessed using the Revised 90-item Symptom Checklist (SCL-90-R).

RESULTS

High-risk gaming prevalence rate was 4.4%. High-risk gamers scored higher on all dimensions of psychopathology, confirming the association between high-risk gaming and psychiatric distress. Regarding substance use, high-risk gamers were more commonly polysubstance users and more commonly made use of psychodysleptic substances. High-risk gamers were more commonly frequent substance users, and 32.5% of high-risk gamers used or had used psychoactive substances often or everyday throughout their lives.

DISCUSSION AND CONCLUSION

The findings are in line with the concept of a common neurobiological vulnerability for both gaming and substance use. There is the need for more research to examine the phenomenology of gaming and its interplay with substance use to help develop effective interventions and prevention strategies.

Risk and protective factor profiles predict addictive behavior among adolescents

BACKGROUND AND AIMS

Internet gaming disorder (IGD), compulsive sexual behavior (CSB), and problematic social network usage (PSNU) are prevalent disorders among adolescents. Research indicates an increase in the number of adolescents engaging in daily gaming, sex, and the use of social networks, as well as an increase in the number of adolescents diagnosed with these disorders. The current study aims to detect unique profiles of risk and protective factors and examine whether these profiles could explain the different severities of IGD, CSB, and PSNU among adolescents.

METHOD

The sample comprised 544 Jewish Israeli adolescents from the general community (age 14-18), who were asked about risk (childhood adversity, childhood trauma, depression, anxiety, stress, post-traumatic stress, self-concealment, internalized stigma) and protective (parent-adolescent communication,) factors and addictive behaviors (IGD, CSB, and PSNU).

RESULTS

Adolescents were classified into three different clusters based on their risk and protective factors: "at risk" (n = 48, 8.82%), "moderate" (n = 400, 73.53%), and "resilient" (n = 96, 17.65%). The "at risk" group had significantly greater severity of addictive behaviors (IGD, CSB, and PSNU) than did the "moderate" or "resilient" groups, and the "moderate" group had significantly greater severity of addictive behaviors than the "resilient" group.

CONCLUSIONS

The findings highlight the fact that protective and risk factor profiles are highly indicative of various addictive behaviors among adolescents. The current research expands knowledge about addictive behaviors by providing a more individualized approach to understanding addictive behaviors among adolescents.

Differences between recreational gamers and Internet Gaming Disorder candidates in a sample of Animal Crossing: New Horizons players

Throughout the last decade, research has considered players' gaming motives as risk and the perceived social support (PSS) as protective factors in the context of Internet Gaming Disorder (IGD). However, the literature is lacking diversity regarding the representation of female gamers as well as of casual and console-based games. The aim of this study was to assess IGD, gaming motives, and PSS comparing recreational gamers and IGD candidates in a sample of Animal Crossing: New Horizons players. A total of 2909 ACNH players (93.7% of them female gamers) took part in an online survey which collected demographic, gaming-related, motivational, and psychopathologic data. Using the cut-off of at least five positive answers to the IGDQ, potential IGD candidates were identified. ACNH players reported a high prevalence rate for IGD (10.3%). IGD candidates differed from recreational players regarding age, sex, and game-related, motivational, and psychopathological variables. A binary logistic regression model was computed to predict membership in the potential IGD group. Age, PSS, escapism and competition motives as well as psychopathology were significant predictors. To discuss IGD in the context of casual gaming, we consider demographic, motivational, and psychopathological player characteristics as well as game design and the COVID-19 pandemic. IGD research needs to broaden its focus concerning game types as well as gamer populations.

Uncovering sample heterogeneity in gaming and social withdrawal behaviors in adolescent and young adult gamers in Hong Kong

OBJECTIVE

The current study aimed to examine the latent heterogeneity of gaming and social withdrawal behaviors in internet gamers and their associations with help-seeking behaviors.

METHOD

The present study recruited 3430 young people (1874 adolescents and 1556 young adults) in Hong Kong in 2019. The participants completed the Internet Gaming Disorder (IGD) Scale, Hikikomori Questionnaire, and measures on gaming characteristics, depression, help-seeking, and suicidality. Factor mixture analysis was used to classify the participants into latent classes based on their latent factors of IGD and hikikomori in separate age groups. Latent class regressions examined the associations between help-seeking and suicidality.

RESULTS

Both adolescents and young adults supported a 4-class, 2-factor model on gaming and social withdrawal behaviors. Over two-third of the sample were classified as healthy or low-risk gamers with low IGD factor means and low prevalence of hikikomori. Around one-fourth was moderate-risk gamers with elevated prevalence of hikikomori, higher IGD symptoms and psychological distress. A minority of the sample (3.8%-5.8%) belonged to high-risk gamers with the highest IGD symptoms and prevalence of hikikomori and heightened suicidal risks. Help-seeking in low-risk and moderate-risk gamers was positively associated with depressive symptoms and negatively associated with suicidal ideation. Perceived usefulness of help-seeking was significantly linked with lower likelihoods of suicidal ideation in the moderate-risk gamers and suicide attempt in the high-risk gamers.

CONCLUSIONS

The present findings explicate the latent heterogeneity of gaming and social withdrawal behaviors and associated factors on help-seeking and suicidality among internet gamers in Hong Kong.

Prevalence and Risk Factors of Internet Gaming Disorder Under the COVID-19 Pandemic Among University Students in Macao

Introduction

During the COVID-19 pandemic, the zero-tolerance policy implemented in Macao affected university students' life and learning styles.

Objectives

This study aimed to investigate the prevalence of internet gaming disorder (IGD) and analyze its risk factors among university students of Macao amid the COVID-19 pandemic.

Methods

Two hundred and twenty-nine university students were recruited by convenience sampling. The cross-sectional investigation was conducted using the 9-item Chinese version of the IGD Scale, the Chinese Version of the Self-Compassion Scale, and the Chinese version of the Brief Resilience Scale.

Results

The prevalence was 7.4%. Compared to Non-IGD gamers, the IGD gamers were more likely to be the older, male gender, with a longer gaming history, with more game hours per day in the last month, and with a lower self-compassion score and resilience.

Conclusion

The prevalence of IGD increased. Students who are the older, male gender, with more gaming time, low self-compassion, and low resilience, have a high possibility of IGD.

Parental Factors Associated With Internet Gaming Disorder Among First-Year High School Students: Longitudinal Study

BACKGROUND

Parents play central roles in adolescents' socialization, behavioral development, and health, including the development of internet gaming disorder (IGD). However, longitudinal research on the parental predictors of adolescent IGD is limited.

OBJECTIVE

This study aimed to investigate the reciprocal associations between various parental factors and adolescent IGD using 2-wave cross-lagged models.

METHODS

A sample of 1200 year-one high school students in central China completed a baseline assessment in 2018 (mean age 15.6 years; 633/1200, 52.8% male) and a follow-up survey in 2019. IGD was measured using the 9-item DSM-5 IGD Symptoms checklist. Perceptions related to parental variables, including psychological control, parental abuse, parental support, and the parent-child relationship, were also collected from the adolescents.

RESULTS

Of all the participants, 12.4% (148/1200) and 11.7% (140/1200) were classified as having IGD at baseline (T1) and follow-up (T2), respectively. All 4 cross-lagged models fit the data well (range for the comparative fit index .91-.95; range for the standardized root mean square residual .05-.06). Parental support (β=-.06, P=.02) and parental abuse (β=.08, P=.002) at T1 predicted IGD symptoms at T2, while parental psychological control (β=.03, P=.25) and a positive relationship with parents (β=-.05, P=.07) at T1 had nonsignificant effects on IGD symptoms at T2, when controlling for background variables. In addition, IGD symptoms at T1 did not predict parental factors at T2.

CONCLUSIONS

The findings suggest that parental factors may be significant predictors of adolescent IGD. Health interventions should consider involving parents to increase the effectiveness of treatment to prevent and reduce adolescent IGD.

Between- and within-person associations of mobile gaming time and total screen time with sleep problems in young adults: Daily assessment study

OBJECTIVES

To explore associations of screen time (total, mobile gaming) with sleep problems in Chinese young adults.

METHODS

This was a 4-week daily morning (completion rate = 82.1%, 909/1107) and evening (completion rate = 92.4%, 1061/1148) assessment study in 41 university students (22 female, mean age = 22.3 [SD 4.2] years). Short sleep duration < 7 h, difficulty initiating sleep, difficulty maintaining sleep, early morning awakening, and any of these three insomnia symptoms were self-reported in the morning. Mobile gaming time was self-reported in the evening, whilst total screen time was objectively tracked. Bayesian multilevel mixed-effects modeling disaggregated between- and within-person associations.

RESULTS

Between person, longer mobile gaming time predicted short sleep duration (adjusted odds ratio [AOR] = 1.90, 95% CI 1.39, 2.69), any insomnia symptoms (AOR = 1.59, 95% CI 1.20, 2.11), difficulty initiating sleep (AOR = 3.05, 95% CI 1.51, 6.24), and difficulty maintaining sleep (AOR = 2.19, 95% CI 1.18, 3.74). Short sleep duration (adjusted b = 0.99, 95% CI 0.05, 1.95), any insomnia symptoms (adjusted b = 1.19, 95% CI 0.24, 1.94), and difficulty initiating sleep (adjusted b = 1.72, 95% CI 0.11, 3.19) reversely increased mobile gaming time. Within person, any insomnia symptoms (adjusted b = 0.17, 95% CI 0.04, 0.31) and early morning awakening (adjusted b = 0.28, 95% CI 0.08, 0.48) increased next-day mobile gaming time. Total screen time was not associated with sleep problems both between and within person.

CONCLUSIONS

Bidirectional between-person associations of mobile gaming time with short sleep duration and insomnia symptoms informed multiple-health-behavior-change interventions. Unidirectional within-person associations of insomnia symptoms with next-day mobile gaming time informed just-in-time adaptive interventions addressing daily variations in insomnia symptoms.

Abnormal psychological performance as potential marker for high risk of internet gaming disorder: An eye-tracking study and support vector machine analysis

Individuals with high risk of internet gaming disorder (HIGD) showed abnormal psychological performances in response inhibition, impulse control, and emotion regulation, and are considered the high-risk stage of internet gaming disorder (IGD). The identification of this population mainly relies on clinical scales, which are less accurate. This study aimed to explore whether these performances have highly accurate for discriminating HIGD from low-risk ones. Eye tracking based anti-saccade task, Barratt impulsiveness scale (BIS), and Wong and Law emotional intelligence scale (WLEIS) were used to evaluate psychological performances in 57 individuals with HIGD and 52 matched low risk of internet gaming disorder (LIGD). HIGD group showed significantly increased BIS total (t = −2.875, p = 0.005), attention (t = −2.139, p = 0.035), motor (t = −2.017, p = 0.046), and non-planning (t = −2.171, p = 0.032) scores, but significantly decreased WLEIS emotion regulation score (t = 2.636, p = 0.010) and correct rate of eye tracking anti-saccade task (t = 2.294, p = 0.024) compared with LIGD group. BIS total score was negatively correlated with the WLEIS total (r = −0.473, p &lt; 0.001) and WLEIS emotion regulation (r = −0.366, p &lt; 0.001) scores. A combination of the WLEIS emotion regulation score and the correct rate of anti-saccade task could discriminate HIGD from LIGD with 91.23% sensitivity, 82.69% specificity, and 87.16% accuracy. Participants with higher gaming hours daily were 40 times more likely to be high risk than their counterparts (p &lt; 0.001). Hence, psychological performances were worse in HIGD. A combination of abnormal emotion regulation and response inhibition might be a potential marker to identify HIGD individuals.

Relationship between time spent playing internet gaming apps and behavioral problems, sleep problems, alexithymia, and emotion dysregulations in children: a multicentre study

BACKGROUND

Internet gaming addiction (IGA) is a serious condition that can significantly impact personal and social functioning. Many studies of IGA have been conducted in adolescents and young adults, but there are limited data available in children. We investigated the time spent using internet gaming apps in children and its association with behavioral problems, sleep problems, alexithymia, and emotional regulation.

METHODS

The research populations (N = 564) were categorized based on the number of hours spent using online gaming applications. The Strengths and Difficulties Questionnaire, the Children's Sleep Habits Questionnaire Abbreviated, the Children's Alexithymia Measure (CAM), and the Clinical Evaluation of Emotional Regulation-9 were used to assess all participants.

RESULTS

Compared to other groups, children who used internet gaming applications for more than 6 h had a higher proportion of abnormal responses on the emotional symptoms and hyperactivity scales. Children who used internet gaming applications for more than 6 h had the poorest sleep quality (75%), while children who used internet gaming applications for 1-2 h had the best (36.7%). Participants who used internet gaming apps for 1-2 h had significantly lower mean total scores on the emotional regulation scale and total CAM, whereas those using internet gaming apps for more than 6 h had the highest mean scores in the CAM.

CONCLUSIONS

Excessive use of internet gaming apps during childhood may be associated with hyperactivity, peer problems, high socioeconomic level, alexithymia concerns, shorter daytime sleep duration, and a delayed morning wake-up.

Development and Internal Validation of a Model for Predicting Internet Gaming Disorder Risk in Adolescents and Children

BACKGROUND

The high prevalence of Internet gaming disorder among children and adolescents and its severe psychological, health, and social consequences have become a public emergency. A high efficiency and cost-effective early recognition method are urgently needed.

OBJECTIVE

We aim to develop and internally validate a nomogram model for predicting Internet gaming disorder (IGD) risk in Chinese adolescents and children.

METHODS

Through an online survey, 780 children and adolescents aged 7-18 years who participated in the survey from June to August 2021 were selected. The least absolute shrinkage and selection operator regression model was used to filter the factors. Multivariate logistic regression analysis was used to establish the prediction model and generate nomograms and a website calculator. The area under the receiver operating characteristic curve, calibration plot, and decision curve analysis were used to evaluate the model's discrimination, calibration, and clinical utility. Bootstrapping validation was used to verify the model internally.

RESULTS

Male sex and experience of game consumption were the two most important predictors. Both models exhibited good discrimination, with an area under the curve >0.80. The calibration plots were both close to the diagonal line (45°). Decision curve analyses revealed that two nomograms were clinically useful when the threshold probability for the intervention was set to 5-75%.

CONCLUSION

Two prediction models appear to be reliable tools for Internet gaming disorder screening in children and adolescents, which can also help clinicians to personalize treatment plans. Moreover, from the standpoint of simplification and cost, Model 2 appears to be a better alternative.

Individual and Interpersonal Factors Associated with the Incidence, Persistence, and Remission of Internet Gaming Disorders Symptoms in an Adolescents Sample

Video game playing behavior has serious consequences for adolescents on a personal, family, social, and academic level. This research aimed to examine risk and protective factors involving incidence, persistence, and remission of gaming disorders symptoms (IGDs) in Spanish adolescents after nine months of follow-up. Data were drawn from self-administered questionnaires completed on two occasions: at the beginning (T1) and end of the academic year (T2). A total of 950 adolescents aged from 11 to 20 years (M = 14, SD = 1.52, 48.5% female) completed the questionnaire at T1, while 550 adolescents aged from 11 to 18 years (M = 13.43, SD = 1.23, 48.9% female) took part in the follow-up study (T2). The incidence, persistence, and remission rates were 6%, 2.7%, and 4.2%, respectively. Significant relationships with IGDs were found between the male gender and studying at a private school in T1 and T2. The findings show that the time spent playing video games during T1 was positively associated with IGDs in T1 and T2. The incidence of IGDs was associated with emotional problems and low family affection. The persistence of IGDs was linked to higher motor impulsivity, agreeableness, and lower family resolve. Remission was related to a decrease in anxiety and hostility as well as an increase in the emotional stability of adolescents. These findings imply that emotional well-being and family adjustment could be relevant for the effective management of gaming behaviors.

Prevalence and risk factors of internet gaming disorder and problematic internet use before and during the COVID-19 pandemic: A large online survey of Japanese adults

Internet gaming disorder (IGD) and problematic internet use (PIU) are becoming increasingly detrimental to modern society, with serious consequences for daily functioning. IGD and PIU may be exacerbated by lifestyle changes imposed by the coronavirus 2019 (COVID-19) pandemic. This study investigated changes in IGD and PIU during the pandemic and risk factors for them. This study is a part of a larger online study of problematic smartphone use in Japan, originally planned in 2019, and expanded in August 2020 to include the impact of COVID-19. 51,246 adults completed an online survey during the pandemic (August 2020), in Japan. Of these, 3,938 had also completed the survey before the onset of the pandemic (December 2019) and were used as the study population to determine how the pandemic has influenced IGD and PIU. IGD was assessed using the Internet Gaming Disorder Scale (IGDS). PIU was measured using the Compulsive Internet Use Scale (CIUS). The prevalence of probable IGD during COVID-19 was 4.1% overall [95%CI, 3.9%-4.2%] (N = 51,246), and 8.6% among younger people (age < 30), 1-2.5% higher than reported before the pandemic. Probable PIU was 7.8% overall [95%CI, 7.6%-8.1%], and 17.0% [95%CI, 15.9%-18.2%] among younger people, 3.2-3.7% higher than reported before the pandemic. Comparisons before and during the pandemic, revealed that probable IGD prevalence has increased 1.6 times, and probable PIU prevalence by 1.5 times (IGD: χ²= 619.9, p < .001, PIU: χ²= 594.2, p < .001). Youth (age < 30) and COVID-19 infection were strongly associated with IGD exacerbation (odds ratio, 2.10 [95%CI, 1.18 to 3.75] and 5.67 [95%CI, 1.33 to 24.16]). Internet gaming disorder and problematic internet use appear to be aggravated by the pandemic. In particular, younger persons and people infected with COVID-19 are at higher risk for Internet Gaming Disorder. Prevention and treatment of these problems are needed.

Longitudinal predictors for incidence of internet gaming disorder among adolescents: The roles of time spent on gaming and depressive symptoms

INTRODUCTION

Internet gaming disorder (IGD) was popular among adolescents worldwide, but whether some associated factors could contribute to the development of IGD was unclear. This longitudinal study explored the temporal stability of IGD over one year and determined the predictors for IGD incidence.

METHODS

Participants were 1121 adolescents from six junior high schools in Shanghai, China (50.6% males; median age = 13.0 years). The baseline and follow-up questionnaire survey measured IGD, time spent on gaming, depressive symptoms, insomnia condition, substance use and background variables from 7th to 8th grade. Multivariate logistic regression analysis was conducted to test the associations between other factors and IGD incidence.

RESULTS

IGD incidence was 7.7% at one-year follow-up. Gender, family financial condition, parental educational level, time spent on gaming, insomnia condition and depressive symptoms were associated with IGD incidence in univariate analysis, whereas only gender, family financial condition, time spent on gaming and depressive symptoms were associated with IGD incidence in multivariate logistic regression.

CONCLUSIONS

IGD might persist for years during adolescence. After controlling for sociodemographic factors, time spent on gaming and depressive symptoms were independent predictors for IGD incidence.

Gaming among Children and Adolescents during the COVID-19 Lockdown: The Role of Parents in Time Spent on Video Games and Gaming Disorder Symptoms

It is mainly children and adolescents who are involved in video gaming. The lockdown caused by the COVID-19 pandemic may have further increased their use of video games and, consequently, the risk of gaming disorder (GD) symptoms. However, currently, we do not have exhaustive knowledge of this issue. To fill this gap, the current study aims to analyze video gaming habits in children and adolescents during the lockdown, starting in March 2020 in Italy, the first European country affected by the pandemic. Specifically, we aim to understand how variables related to parents—for instance, knowledge of their offspring’s life, the monitoring of their video gaming habits, and parental use of video games—are related to their offspring’s time spent on video games and GD symptoms. A web-based survey involving parents (n = 554, 79% mothers, mean age = 45.39) of 554 children and adolescents (73% males, mean age = 11.11) was utilized. The results showed that they were involved in video games, particularly boys and adolescents, with high rates of GD symptoms. The parents also spent a considerable amount of time playing video games. A path model that explained the mechanisms through which parental variables were related to their offspring’s time spent on video games and GD symptoms, controlling for gender and age, was verified. Overall, the findings indicate the importance of educating parents to behave effectively with respect to video games and monitor their offspring’s video gaming habits.

Associations Between Attention Deficit/Hyperactivity Disorder and Internet Gaming Disorder Symptoms Mediated by Depressive Symptoms and Hopelessness Among College Students

PURPOSE

The mediating role of depressive symptoms and hopelessness on the relationship between attention deficit/hyperactivity disorder (ADHD) and internet gaming disorder (IGD) symptoms has not yet been elucidated. This study assessed this mediating effect in college students.

PARTICIPANTS AND METHODS

Participants consisted of 1236 freshmen recruited at a local university. Symptoms of ADHD, IGD, depression and hopelessness were measured using self-report scales. The effect of ADHD on IGD mediated by depression and hopelessness was analyzed by Haye's PROCESS macro for SPSS (Model 6) using the bias-corrected percentile bootstrap method with 5000 bootstrapped samples.

RESULTS

Symptoms of ADHD, depression and hopelessness were common in college students and were strongly associated with the appearance of IGD symptoms. ADHD symptoms of college students impacted their IGD symptoms directly and indirectly via depressive symptoms and hopelessness. The total effect of ADHD symptoms on IGD symptoms was 0.075 (standard error [SE]: 0.009, 95% confidence interval [CI] 0.057, 0.093), with a direct effect of 0.037 (SE: 0.010, 95% CI 0.018, 0.056, effect ratio: 49.3%), and total indirect effect was 0.038 (SE: 0.005, 95% CI 0.029, 0.050, effect ratio: 50.7%).

CONCLUSION

Depressive symptoms and hopelessness can mediate the relationship between ADHD and IGD symptoms among college students. These findings point to the importance of evaluating ADHD, depressive and hopelessness symptoms for the prevention and treatment of adult IGD.

Preschool Exposure to Online Games and Internet Gaming Disorder in Adolescents: A Cohort Study

Objectives: Although considerable evidence has already been collected on the effects of early initiation of drug/alcohol consumption on addictive behaviors in adolescents, little is known about the impact of early exposure to online games during preschool ages on the risk of internet gaming disorder (IGD). We evaluated the effects of exposure to online games before entering elementary school on IGD occurrence during the secondary school years using a community-based longitudinal study. Methods: Data from 1,760 adolescents (seventh grade), who were recruited from the iCURE study and followed for 2 years, were analyzed. A high risk of IGD (HRIGD) was assessed by the Internet Game Use Elicited Symptom Screen, a self-reported questionnaire based on the fifth version of DSM-5 IGD criteria. Early exposure to online gaming was defined as when adolescents played online games during their preschool years. A multivariate generalized-estimating-equation model was applied to examine the independent risk factor of the occurrence of HRIGD during the 2-year follow-up period. Results: As compared with the later-exposure group, those with early exposure to online games showed an ~1.7-fold greater incidence of HRIGD over the 2-year follow-ups after adjusting for potential confounders including baseline IGD scores (adjusted relative risk:1.69; 95%confidence interval:1.08-2.66). Pre-specified sensitivity analyses showed that the results were robust. Conclusion: Exposure to online gaming during the preschool years increases the likelihood of occurrence of HRIGD in adolescence. Restricting exposure to online games during the preschool years should be examined as a way to reduce the risk of IGD in adolescents.
