Adverse childhood experiences on internet gaming disorder mediated through insomnia in Chinese young people.

Adverse childhood experiences (ACEs) have been associated with addictions such as substance use disorders. Few have examined ACEs on internet gaming disorder (IGD) as a newly established behavioral addiction, and the potential mediating role of insomnia remains unclear. We examined the associations between ACE number and types, IGD, and insomnia. Participants included 1, 231 Chinese university students (54.5% male; 56.9% aged 18-20 years) who had played internet games at least once in the previous month. ACEs were measured using the 10-item ACE questionnaire (yes/no). Symptoms of insomnia and IGD were measured using the Insomnia Severity Index and the 9-item Internet Gaming Disorder Scale-Short-Form, respectively. Multivariable regressions examined the associations, adjusting for sex, age, maternal and paternal educational attainment, monthly household income, smoking, and alcohol drinking. The mediating role of insomnia symptoms was explored. The prevalence of ACEs≥1 was 40.0%. Childhood verbal abuse was the most prevalent (17.4%), followed by exposure to domestic violence (17.1%) and childhood physical abuse (15.5%). More ACE numbers showed an association with IGD symptoms (adjusted OR = 1.11, 95% CI 1.04, 1.17). Specifically, IGD symptoms were observed for childhood physical neglect, emotional neglect, sexual abuse, parental divorce or separation, and household substance abuse. Insomnia symptoms mediated the associations of ACE number and types with IGD symptoms (proportion of total effect mediated range 0.23-0.89). The number and specific types of ACEs showed associations with IGD mediated through insomnia. Screening of ACEs is recommended in future studies on IGD. Longitudinal data are warranted to determine the causality of the observed associations.

Development of a Novel Method of Assessing Potential Loss of Control in Internet Gaming Disorder.

As video game play has increased in popularity, so too have reports that a subset of individuals play games in a way that causes negative consequences to their lives, which has resulted in the proposed inclusion of Internet Gaming Disorder (IGD) as a formal mental health diagnosis. Given the mass popularity of video games, it is critical that screening materials for this proposed disorder are sufficiently sensitive to ensure that individuals who suffer harm are identified, while those who do not are not mislabeled as such. Here we examined the extent to which participants' responses to a typical IGD questionnaire predicted academic behaviors that could be associated with harm. We recruited 42 college students and tracked their gaming and studying habits weekly over the course of one semester, taking particular note of weeks in which participants did or did not have exams. We predicted that college students overall would spend less time engaging with video games and more time with academics when they had exams, but such modulations would be smaller among individuals with more initial IGD symptoms (i.e., the "more IGD symptoms" group, as compared to the "fewer IGD symptoms" group, would show loss of control). We did not find that college students overall spent less time engaging with video games and more time with academics when they had exams, but post-hoc effect size analyses indicated that our study was underpowered. Implications of potential results using this methodology are discussed and estimates of powerful sample sizes are provided.

Effectiveness of narrative health message on attitude towards gaming disorder among adolescents at selected school of Patna

Background: Games are generally seen to be beneficial activities but recently it gave rise concern towards people who play digital/video games for prolong hours as it interferes with personal, professional and academics, which is defined as symptoms of internet gaming disorder, that has been recently added in ICD-11 and DSM-5 for further study. Knowledge regarding IGD will help to prevent further prevalence of IGD and manage its harmful physical and mental issue. This study aimed to assess the prevalence of Internet gaming disorder among adolescent students at selected school of Patna, to evaluate the effectiveness of narrative health message on attitude towards gaming disorder among adolescents at selected school of Patna and to determine the association between demographical variables and pre-test attitude score. Methods: A quantitative research approach and pre-experiment (one group pre-test post-test) research design was used. About 76 participants were selected for the study using convenient sampling technique from class 8, 9 and 10 from selected school of Patna. Data was analysed by using descriptive and inferential statistics. Results: In pre-test 88.2% participants had positive attitude and 11.8% had negative attitude regarding internet gaming disorder. After implementation of narrative health message there were 92.1% participants had positive attitude and 7.9% had negative attitude The mean post-test attitude score of 76.91±11.717 was higher than the mean pre-test attitude score of 71.62±9.874. The calculated ‘t’ valve 4.421 was significant at p value 0.001. Conclusions: The study concludes that narrative health message regarding internet gaming disorder was effective.

Assessment of Hazardous Gaming in children and its dissimilarities and overlaps with Internet Gaming Disorder.

Children have been vastly overlooked in Internet Gaming Disorder (IGD) and Hazardous Gaming research so far. The diagnoses are listed in different ICD-11 chapters (addiction vs. problematic health condition) and are thus considered as distinct constructs. However, screening tools for children do not exist yet. We aimed to investigate the psychometric properties of an existing IGD screening tool modified to also assess Hazardous Gaming in children. Further, we aimed to compare the dissimilarity and overlap between (subclinical) IGD and Hazardous Gaming in children. The study analyzed data from a mixed school and clinical sample. Data from N = 871 children aged between 8 and 12 years of age (M = 10.3, SD = 0.90) were analyzed. Data were collected via the Video Game Dependency Scale (CSAS) in its parent report version, which was adapted to assess Hazardous Gaming symptoms in addition to the IGD symptoms. Item analyses and reliability and factor analyses were conducted on the Hazardous Gaming version. The results show that the adapted CSAS version that assesses Hazardous Gaming symptoms in children mostly shows acceptable psychometric properties. Explorative Factor Analysis (EFA) shows a two-factor structure with one factor of higher order. Additionally, results show that 35.2% of all children meeting the threshold for Hazardous Gaming exclusively meet criteria for Hazardous Gaming but not for (subclinical) IGD. Vice versa, 91.3% of children with IGD also meet the criteria for Hazardous Gaming. Hazardous Gaming and (subclinical) IGD are distinct constructs with some overlaps and might have a temporal relation. We recommend adding four items to assess Hazardous Gaming using the CSAS and further evaluate the validity. The assessment of Hazardous Gaming in children is crucial because it might occur earlier than subclinical or full-syndrome IGD.

Unravelling the intricacies between gaming motivations and internet gaming disorder symptoms in adolescents: a network analysis of 2-year healthy and deteriorating transition profiles

BackgroundThe increasing prevalence of internet gaming disorder (IGD) among adolescents has become a global concern, while gaming plays a large role in many adolescents’ lives. While prior research emphasised the significance of investigating IGD through an etiological lens, the interconnections between diverse gaming motivations and IGD symptoms in adolescents remain inadequately understood. This study explored the associations between distinct gaming motivations and IGD symptoms by conducting network analysis in adolescents.MethodsData from a two-year longitudinal school-based survey (N = 2148) was utilized. LPA was used to offer a straightforward and interpretable solution for identifying adolescents with two-year healthy and deteriorating transitions of IGD profiles. Subsequently, we conducted a network analysis to explore and compare the associations between gaming motivations and IGD symptoms in adolescents with two-year healthy transition profiles and deteriorating transition profiles.ResultsThree profiles were delineated: ‘low IGD’ (T1: n = 808, 37.62%; T2: n = 731; 34.03%), ‘middle IGD’ (T1: n = 1063, 49.49%; T2: n = 1103, 51.35%), and ‘severe IGD’ (T1: n = 277, 12.89%; T2: n = 314, 14.62%), classifying adolescents with healthy transitions and those with deteriorating transitions. Three gaming motivations (i.e., ‘Daily entertainment’, ‘I am good at it’, and ‘Improvement of ability and mindset’) were identified as protective motivations. Two others, ‘Enjoy being in the gaming world’ and ‘Preoccupation’, were identified as bridge nodes in adolescents with deteriorating transitions. Three core nodes (i.e., ‘Sense of victory’, ‘Enjoy being in the gaming world’, and ‘Sense of achievement’) were identified in both adolescents with healthy profile transitions and deteriorating transitions.ConclusionFindings suggest that not all gaming motivations contribute to the development of IGD in adolescents. Adolescents with deteriorating transitions showed specific gaming motivation and IGD symptom that is closely connected. Future interventions should consider corresponding gaming motivation when addressing IGD among adolescents.

Relapse prevention therapy for internet gaming disorder in Swedish child and adolescent psychiatric clinics: a randomized controlled trial

ObjectivesTo evaluate the effectiveness of relapse prevention (RP) as a treatment for internet gaming disorder (IGD).DesignRandomized controlled trial.SettingThree child and adolescent psychiatry (CAP) units in Region Skåne, Sweden.ParticipantsChildren aged 13–18 years, coming for their first visit to CAP during 2022, were screened for gaming behavior. Those who met the proposed DSM-5 criteria for IGD were offered participation in the trial, if they had the capacity to provide written informed consent and if they spoke Swedish. A total of 111 CAP patients agreed to participate. Out of those, 11 patients were excluded due to incorrect inclusion such as young age (n = 1), or due to the absence of responses to follow-up measures (n = 9). After exclusion, 102 participants remained (intervention = 47, control = 55).InterventionsThe intervention, RP, is based on cognitive behavioral treatment (CBT) and was provided individually, comprising of five to seven 45-min sessions over a period of 5 to 7 weeks versus treatment as usual.Outcome measuresParticipants were assessed with Game Addiction Scale for Adolescents pre-treatment (GASA) (baseline), post-treatment (treatment group only), and 3 months after baseline (follow-up).ResultsThe repeated measures ANOVA showed a significant interaction effect between treatment and time. Both the control group and treatment group lowered their mean GASA score from baseline to follow-up significantly, but the improvement was greater in the treatment group (mean difference in control group −5.1, p < 0.001, 95% CI = − 3.390 to −6.755, mean difference in treatment group −9.9, p < 0.001, 95% CI = −11.746 to −8.105).ConclusionRP was found to be superior to treatment as usual in terms of reduction of IGD symptoms. Future research should address which aspects within a given treatment are effective, who benefits from treatment, in what aspects, and why.Trial registration numberClinicalTrials.gov, NCT05506384 https://clinicaltrials.gov/ct2/show/NCT05506384.

Relationships of internet gaming engagement, history, and maladaptive cognitions and adolescent internet gaming disorder: A cross-sectional study.

This study tested the mediation effect of maladaptive cognition of internet gaming and moderation effect of internet gaming history in the relationship between internet gaming engagement and internet gaming disorder in adolescents. A total of 2,902 secondary school students were surveyed in Hong Kong from February 2021 to December 2021. The proposed moderated mediation model was tested by PROCESS. Internet gaming engagement, internet gaming history and maladaptive cognition were positively associated with internet gaming disorder symptoms. Maladaptive cognition significantly mediated the association between internet gaming engagement and internet gaming disorder symptoms in both males and females. In addition, a significant interaction between internet gaming engagement and internet gaming history was detected among females but not for males, namely, the positive relationships of internet gaming engagement with maladaptive cognition and internet gaming disorder symptoms were weaker with the increased years of internet gaming. Our study provides a better understanding of the underlying mechanism and boundary condition in the association between internet gaming engagement and internet gaming disorder among adolescents. Preventing interventions should aim to reduce maladaptive cognition and internet gaming engagement. Interventions targeting internet gaming engagement maybe more effective among female gamers who are beginners and all male gamers.

A Systematic Review of Pharmacological Treatments for Internet Gaming Disorder.

Internet gaming disorder (IGD) is an increasingly common behavioral addiction, with an estimated global prevalence of 3%. A variety of pharmacological treatments have been used to treat IGD, yet no review to date has synthesized clinical trials evaluating their efficacy. This systematic review therefore synthesized the literature reporting on clinical trials of pharmacological treatments for IGD. We reviewed articles from MEDLINE, Embase, PubMed Central, CINAHL, and PsycINFO that were published as of March of 2022. A total of 828 articles were retrieved for review and 12 articles were included, reporting on a total of 724 participants. Most participants were male (98.6%), and all were currently living in South Korea. The most common drugs used to treat IGD were bupropion, methylphenidate, and a range of selective serotonin reuptake inhibitors. The Young Internet Addiction Scale was the most frequently used to measure gaming-related outcomes. All studies reported reduced symptoms of IGD from pre- to post-treatment. Across all clinical trials, IGD symptom reductions following the administration of pharmacological treatments ranged from 15.4% to 51.4%. A risk of bias assessment indicated that only four studies had a low risk of bias. Preliminary results suggest that a wide array of pharmacological interventions may be efficacious in the treatment of IGD. Future studies using double-blind randomized controlled trial designs, recruiting larger and more representative samples, and controlling for psychiatric comorbidities are needed to better inform understanding of pharmacological treatments for IGD.

Prevalence and associated factors of depressive and anxiety symptoms among Chinese secondary school students

BackgroundDepressive and anxiety symptoms affect about one-fourth of Chinese secondary school students. However, the prevalence and correlates of mental distress among secondary school students from Western China remain largely unexplored. This study aimed to examine the prevalence and associations of depressive and anxiety symptoms with demographic, family, school, life, and behavior factors in a large, representative sample of secondary school students in Zigong, a city in Western China.MethodsSecondary school students were recruited using cluster sampling. The 9-item Patient Health Questionnaire, the 7-item Generalized Anxiety Disorder Questionnaire, Multidimensional Peer-Victimization Scale, the Pittsburgh Sleep Quality Index, and Nine-Item Internet Gaming Disorder Scale-Short Form were used. Descriptive statistic was used to describe the sociodemographic characteristics of participants. The clustering effect was adjusted by the “survey” package of R to calculate weighted prevalence. Univariate and multivariate logistic regression were used to explore associated factors of depression and anxiety, respectively.ResultsA total of 63,205 participants were involved, in which the weighted prevalence of depression in all subjects was 23.0% (95% CI: 19.6- 27.0%), and the weighted prevalence of anxiety was 13.9% (95% CI: 11.2- 17.0%). Logistic regression results showed girls, being single-child, non-nuclear family, peer bullying, sleep disturbance, and internet gaming disorder symptoms were positively associated with depressive and anxiety symptoms.ConclusionDepressive and anxiety symptoms were prevalent among secondary school students in Western China. Our results can guide policy strategies for the assessment, prevention, and intervention of psychological status among Chinese secondary school students.

The role of negative and positive urgency in the relationship between craving and symptoms of problematic video game use

Craving and emotion-driven impulsivity dimensions (positive and negative urgency) have been suggested as factors involved in the progression of different potentially problematic behaviors. However, their role in severity of video gaming-related problems remains unclear. This study aims to assess the differential capacity of negative and positive urgency to predict craving and the number of internet gaming disorder (IGD) symptoms endorsed (as a proxy to severity of video gaming problems) in majoritarily non-pathological video-gamers. Convenience sampling was used to recruit 232 Spanish and 222 Ecuadorian frequent video game players. Mixed-effects generalized linear (GMLE) and mediation modeling were used to test moderation and mediation hypotheses regarding the association between urgency, craving, and endorsement of IGD symptoms. Results show that (1) craving largely overlaps with endorsement of IGD symptoms; (2) craving for video games is linked to positive urgency, but not to negative urgency, which reinforces the idea that craving, at least in mostly non-pathological gamers, is a positively valenced expectancy state; (3) positive urgency exerts an indirect effect (mediated by craving) on the number of symptoms endorsed; (4) negative urgency exerts a direct effect on the number of symptoms endorsed; and (5) urgency traits do not interact with craving to predict the number of symptoms. These findings are consistent with the proposal that craving is an emotional state, and that dysregulation of positive affect (as measured by positive urgency) influences its emergence and control. In addition, they support the idea that craving is a central feature in the emergence of IGD symptoms.

Enhanced Pavlovian-to-instrumental transfer in internet gaming disorder

The Pavlovian-to-instrumental transfer (PIT) effect is a phenomenon that Pavlovian conditioned cues that could influence one's instrumental behavior. In several substance and behavioral addictions, such as tobacco use disorder and gambling disorder, addiction-related cues could promote independently trained instrumental drug-seeking/drug-taking behaviors, indicating a specific PIT effect. However, it is unclear whether Internet gaming disorder (IGD) would show a similar change in PIT effects as other addictions. The study aimed to explore the specific PIT effects in IGD. We administrated a PIT task to individuals with IGD (n = 40) and matched health controls (HCs, n=50), and compared the magnitude of specific PIT effects between the two groups. The severity of the IGD symptoms was assessed by the Chinese version 9-item Internet Gaming Disorder Scale (IGDS) and the Internet Addiction Test (IAT). We found that: (1) related to the HCs group, the IGD group showed enhanced specific PITgame effects, where gaming-related cues lead to an increased choice rate of gaming-related responses; (2) in the IGD group, the magnitude of specific PITgame effects were positively correlated with IAT scores (rho = 0.39, p = 0.014). Individualswith IGD showed enhanced specific PIT effects related to HCs, which were associated with the severity of addictive symptoms. Our results highlighted the incentive salience of gaming-related cues in IGD.

Whether and How Parental and Friends’ Internet Gaming Behaviors May Affect Adolescent Internet Gaming Disorder Symptoms: the Cognitive and Behavioral Mechanisms

Whether and How Parental and Friends’ Internet Gaming Behaviors May Affect Adolescent Internet Gaming Disorder Symptoms: the Cognitive and Behavioral Mechanisms

Prevalência do transtorno do jogo pela internet e seus correlatos psicológicos

ABSTRACT Objective To investigate the prevalence of internet gaming disorder (IGD) symptoms in a sample of Brazilian adults, and its association with personality, psychiatric symptoms and psychosocial measures. Methods We evaluated 219 adults online recruited using questionnaires and psychometric scales. We evaluated the behavior and pattern of internet games using the Game Addiction Scale (GAS). We tested the association of the previous measures with the GAS scores by spearman correlations and multiple regression analysis. Results Of our sample, 74% played games online. We found correlations between IGD symptoms and most symptoms of mental disorders, with small or moderate effect sizes, as well as correlations with the personality traits of agreeableness (r = -0.272; p < 0.001), conscientiousness (r = - 0.314; p < 0.001), and neuroticism (r = 0.299; p < 0.001). Additionally, we found a negative association with psychosocial outcomes such as quality of life (r = -0.339; p < 0.001) and life satisfaction (r = - 0.202; p < 0.003). The multivariate model included the personality traits of conscientiousness and agreeableness and symptoms of dissociation and somatization as predictors. The prevalence of IGD was 9% in those who played online games. Conclusion IGD is correlated with different areas of the individual’s life, such as personality, quality of life, and several common symptoms of mental disorders. The prevalence can be considered high among players (9%). Conscientiousness, agreeability, somatic symptoms, and dissociative symptoms were associated with the symptoms of IGD.

Cross-Cultural Efficacy of the Acceptance and Cognitive Restructuring Intervention Program (ACRIP) on the Internet Gaming Disorder Symptoms of Selected Asian Adolescents.

Empirical evidence shows that Internet Gaming Disorder (IGD) with poor psychological well-being increases. IGD hasbecome an emerging issue of significant public health concern andthe World Health Organization has recently recognized it as a mental health condition. This study examined the efficacy of the Acceptance and Cognitive Restructuring Intervention Program (ACRIP) in reducing the symptoms of IGD and improving the psychological well-being of adolescent gamers from select Asian cultures after proving it effective in a prior study in the Indian setting. The development of the ACRIP employed a sequential exploratory research design and randomized controlled trial on thirty participants. Internet Gaming Disorder (IGDS9-SF) and Ryff's Psychological well-being (PWB) scales were used to measure the severity of the gaming disorder and the state of psychological health of the experimental and control groups. Power analysis ascertained the study with a power of 0.90, indicating a strong probability of obtaining a statistically significant effect. Statistical analyses using paired t-test and MANOVA on post-test mean scores on IGD and PWB of the experimental group showed a significant difference which suggested that the ACRIP is efficacious and culture-free.

Effects of Transcranial Electrical Stimulation on Gambling and Gaming: A Systematic Review of Studies on Healthy Controls, Participants with Gambling/Gaming Disorder, and Substance Use Disorder.

Gambling disorder (GD) and internet gaming disorder (IGD) are formally recognized behavioral addictions with a rapidly growing prevalence and limited treatment options. Recently, transcranial electrical stimulation (tES) techniques have emerged as potentially promising interventions for improving treatment outcomes by ameliorating cognitive functions implicated in addictive behaviors. To systematize the current state of evidence and better understand whether and how tES can influence gambling and gaming-related cognitive processes, we conducted a PRISMA-guided systematic review of the literature, focusing on tES effects on gaming and gambling in a diverse range of population samples, including healthy participants, participants with GD and IGD, as well as participants with substance abuse addictions. Following the literature search in three bibliographic databases (PubMed, Web of Science, and Scopus), 40 publications were included in this review, with 26 conducted on healthy participants, 6 focusing on GD and IGD patients, and 8 including participants with other addictions. Most of the studies targeted the dorsolateral prefrontal cortex, using transcranial direct current stimulation (tDCS), and assessed the effects on cognition, using gaming and gambling computerized cognitive tasks measuring risk taking and decision making, e.g., balloon analogue risk task, Iowa gambling task, Cambridge gambling task, etc. The results indicated that tES could change gambling and gaming task performances and positively influence GD and IGD symptoms, with 70% of studies showing neuromodulatory effects. However, the results varied considerably depending on the stimulation parameters, sample characteristics, as well as outcome measures used. We discuss the sources of this variability and provide further directions for the use of tES in the context of GD and IGD treatment.

The role of executive function deficits, delay aversion and emotion dysregulation in internet gaming disorder and social media disorder: Links to psychosocial outcomes.

It has been argued that it is important to consider underlying mechanisms of mental health problems. Previous studies have shown that executive deficits, delay aversion, and emotion dysregulation are related to Internet Gaming Disorder (IGD) and Social Media Disorder (SMD). However, the present study is the first to investigate whether these neuropsychological deficits show additive effects or if they interact. The present study also investigated whether these deficits mediate the association between IGD/SMD and psychosocial outcomes. The study involved 995 university students who completed a survey measuring IGD/SMD symptom severity, neuropsychological functions, and psychosocial outcomes. Both dimensional and categorical analyses were used to assess the associations between neuropsychological functions and IGD/SMD. Simple and multiple mediation analyses were conducted to examine if neuropsychological functioning mediates the association between IGD/SMD and psychosocial outcomes. All neuropsychological functions were significantly associated with both IGD and SMD symptom severity. However, only inhibition and emotion regulation, as well as delay aversion for SMD, remained significant when controlling for the overlap between different functions. Associations were significantly stronger for men compared to women for IGD. In the categorical analyses, individuals with IGD/SMD were more likely to have neuropsychological deficits (odds ratios between 3.33 and 8.81). Finally, all neuropsychological functions, except inhibition, were significant mediators in the link between IGD/SMD and psychosocial outcomes. These results shed light on the neuropsychological underpinnings of IGD/SMD, which can be used to identify more homogenous subgroups and provide more individualized treatment options.

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

ObjectiveThe 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. ResultsBoth 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. ConclusionsThe 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.

Symptoms of internet gaming disorder and depression in Chinese adolescents: A network analysis

The current study aimed to investigate comorbidity among symptoms of depression and internet gaming disorder (IGD) utilizing symptom network analysis in a sample of Chinese adolescents. A total of 1,362 Chinese adolescents (Mean age = 15.19 ± 1.67; range 13–21; 39.79% female, 56.02% male, 4.19% not disclosed) were recruited from 11 local secondary schools between June and July 2020. Symptoms of depression and IGD were assessed by the 7-item DASS-21 depression subscale and the 9-item Internet Gaming Disorder Scale. We conducted network analysis to estimate network models and the most central symptoms of depression and IGD and computed a combined network model of both depression and IGD symptoms to find bridge symptoms and illustrate the comorbidity between depression and IGD. We found that feeling ‘Worthless’, ‘Meaningless’, and ‘Down-hearted’ were identified as the most central symptoms of depression, whereas ‘Preoccupation’ and ‘Tolerance’ were the two most central symptoms of IGD. The bridge symptoms in the combined network model were ‘Gaming for escape or mood relief’ from the IGD cluster and ‘No initiative’ and ‘Down-hearted” from the depression cluster. The current study was the first to investigate the relationship between depression and IGD symptoms among adolescents utilizing a symptom network perspective. Also, it highlighted key bridge symptoms in understanding how IGD and depression contribute to each other.

EEG Parameter Selection Reflecting the Characteristics of Internet Gaming Disorder While Playing League of Legends.

Game playing is an accessible leisure activity. Recently, the World Health Organization officially included gaming disorder in the ICD-11, and studies using several bio-signals were conducted to quantitatively determine this. However, most EEG studies regarding internet gaming disorder (IGD) were conducted in the resting state, and the outcomes appeared to be too inconsistent to identify a general trend. Therefore, this study aimed to use a series of statistical processes with all the existing EEG parameters until the most effective ones to identify the difference between IGD subjects IGD and healthy subjects was determined. Thirty subjects were grouped into IGD (n = 15) and healthy (n = 15) subjects by using the Young's internet addition test (IAT) and the compulsive internet use scale (CIUS). EEG data for 16 channels were collected while the subjects played League of Legends. For the exhaustive search of parameters, 240 parameters were tested in terms of t-test, factor analysis, Pearson correlation, and finally logistic regression analysis. After a series of statistical processes, the parameters from Alpha, sensory motor rhythm (SMR), and MidBeta ranging from the Fp1, C3, C4, and O1 channels were found to be best indicators of IGD symptoms. The accuracy of diagnosis was computed as 63.5-73.1% before cross-validation. The most interesting finding of the study was the dynamics of EEG relative power in the 10-20 Hz band. This EEG crossing phenomenon between IGD and healthy subjects may explain why previous research showed inconsistent outcomes. The outcome of this study could be the referential guide for further investigation to quantitatively assess IGD symptoms.

Network analysis of internet gaming disorder, problematic social media use, problematic smartphone use, psychological distress, and meaning in life among adolescents

Background Few studies have examined the connections between psychological distress, meaning in life, internet gaming disorder (IGD), problematic smartphone use (PSU), and problematic social media use (PSMU). Methods The central and bridging nodes of IGD, PSMU, and PSU symptoms were investigated using network analysis in China among 742 adolescents ( Mage = 15.39, SD = 1.68, range = 12–19; 53.23% female). The relationships between IGD, PSMU, and PSU and associated factors were investigated using a Directed Acyclic Graphs method. Results The results suggested that the central symptoms were withdrawal in IGD, mood modification in PSU, and tolerance in PSMU. Mood modification in IGD, mood modification in PSU, withdrawal in PSMU, and functional impairment in PSMU were the bridge symptoms. Males were more likely to experience symptoms of IGD than females, while females were more likely to need meaning than males. Stress is the root factor, while depression, meaning confusion, meaning anxiety, and meaning avoidance were closely associated with IGD, PSMU, and PSU. Conclusions The current research improved the understanding of IGD, PSMU, and PSU symptoms in teenagers and demonstrated the potential of dynamic systems perspectives on problematic use behaviors and stress/meaning-focused interventions.
