A Network Analysis of the Internet Gaming Disorder Scale–Short-Form (IGDS9-SF): An Intercontinental Large-Scale Study

AbstractThe present study aimed to use a novel method (i.e., network analysis) to examine if the Internet Gaming Disorder Scale–Short-Form (IGDS9-SF) has its unidimensional structure supported across different subgroups, including gender groups, continent groups, and age groups. Participants from five continents (n = 545 in Africa; n = 27,910 in Americas; n = 4640 in Asia; n = 88,835 in Europe; and n = 1633 in Oceania) completed the IGDS9-SF. The IGDS9-SF items showed a positively correlated network with moderate-to-high predictability (mean of R2 = 0.338, SD = 0.068). Moreover, the network analysis results suggested that the IGDS9-SF is very likely to have a one-factor model. This one-factor model was further found to be invariant across gender groups (men vs. women), continent groups (Africa, Americas, Asian, Europe, and Oceania), and age groups (minor aged under 18 years, young adults aged between 18 and 30 years, and adults aged 30 years or above).

The mediating effect of dispositional mindfulness on the association between UPPS-P impulsivity traits and gaming disorder among Asia-Pacific young adults

BackgroundLittle evidence is available to verify the mediating effect of dispositional mindfulness on the association between gaming disorder and various impulsivity traits. The present study aimed to investigate the mediating effect of dispositional mindfulness on the association between the five UPPS-P impulsivity traits and the risk of gaming disorder among young adults.MethodsIt was an inter-regional cross-sectional study using online survey in Australia, Japan, The Philippines and China. Impulsivity measured by the UPPS-P Impulsive Behavior Scale–Short version; dispositional mindfulness measured by the Mindfulness Attention Awareness Scale; and the risk of gaming disorder measured by the Internet Gaming Disorder Scale were collected in the focal regions. Structural equation modeling was performed by SPSS AMOS version 26 to verify the study hypotheses. Bootstrapped 95% confidence interval was reported. Statistical significance was indicated by the p-value below 0.05.ResultsAmong the 1,134 returned questionnaires, about 40% of them aged 18–20 years and 21–23 years, respectively. 53.8% were male. 40.7% had been playing digital and video games for over 10 years. The prevalence of gaming disorder was 4.32%. The model fitness indices reflected that the constructed model had an acceptable model fit (χ2(118) = 558.994, p < 0.001; χ2/df = 4.737; CFI = 0.924; TLI = 0.890; GFI = 0.948; RMSEA = 0.058; SRMR = 0.0487). Dispositional mindfulness fully mediated the effect of positive urgency and negative urgency on the risk of gaming disorder. The effect of lack of premeditation on the risk of gaming disorder was partially mediated by dispositional mindfulness. However, dispositional mindfulness did not mediate the effect of sensation seeking on the risk of gaming disorder.ConclusionsThe varied associations between dispositional mindfulness and the five impulsivity traits hints that improving some impulsive traits may increase dispositional mindfulness and so lower the risk of gaming disorder. Despite further studies are needed to verify the present findings, it sheds light on the need to apply interventions on gamers based on their impulsivity profile. Interventions targeting at emotion regulation and self-control such as mindfulness-based interventions seem to be effective to help gamers with dominant features of urgency and lack of premeditation only. Other interventions shall be considered for gamers with high sensation seeking tendency to enhance the effectiveness of gaming disorder prevention.

Sociodemographics, playing Habits, adherence to the Mediterranean dietary pattern, dietary supplements intake, physical activity level, and degree of Internet gaming disorder of Portuguese chess players

Introduction: Lifestyle and gaming habits may influence chess players' adhesion to healthy dietary patterns. This study aims to characterize Portuguese chess players sociodemographics, playing traits, adherence to the Mediterranean diet (MD), dietary supplement (DS) consumption, physical activity level, degree of internet gaming disorder (IGD) and to study predictors of adherence to the MD. Methods: Data was gathered using an online survey disseminated through social networks, which included questions regarding sociodemographics, chess playing habits, the PREDIMED questionnaire, DS consumption, the International Physical Activity Questionnaire, and the Internet Gaming Disorder Scale. Results: The 192 respondents (93.8 % males) had a mean of 41 years (SD = 14), high education (mean = 15.1 y, SD = 1.7), and played chess for 6.3 hours (SD = 9.7) a week. Most (58.9 %, n = 113) reported moderate adherence to the MD, 30.2 % (n = 58) ingested DS, 64.1 % (n = 123) adhered to the WHO Physical Activity Recommendations, and no subject was classified with IGD. Higher Elo scores correlated with higher red/processed meat consumption (OR = 4.935, p = 0.005). A greater volume of chess play related to higher consumption of pastries and sweets (OR = 3.127, p = 0.007). Higher IGD scores were associated with lower adhesion to the MD (OR = 1.067, p = 0.019). Conclusions: The most dedicated chess players may be less concerned with maintaining a balanced diet and may require supervision from health professionals. Funding: None to disclose.

From classrooms to controllers: how school closures shaped children's video gaming habits.

This study aimed to assess the impact of COVID-19-related school closures on screen time and video gaming habits among governmental school students in Qatar and explore the prevalence of Internet Gaming Disorder (IGD) within this context. A cross-sectional approach was employed, spanning two months from June to August 2022. A random sample of students aged 8-15 years was drawn from the national electronic health record system of Qatar. Telephone interviews with parents were conducted to collect data. The Parental Internet Gaming Disorder Scale (PIGDS) was used for IGD assessment. Of 428 parents, 257 (60%) confirmed their child's engagement in video gaming during school closures. Participants averaged 11 years in age with 92 (35.8%) females and 165 (64.2%) males. Nationality included 62.6% expatriates and 37.4% Qatari locals. Average weekly screen time increased significantly from 19.7 ± 10.1 h to 31.9 ± 12.6 h during closure (p < 0.001). Video gaming time rose from 8.6 ± 8.6 h to 13.0 ± 12.4 h per week (p < 0.001). The prevalence of IGD was 8.6% (95% CI 5.4-12.7). Male students, expatriates, and those reporting increased video gaming time were more likely to develop IGD than their female and local counterparts. The observed associations between video gaming increase and IGD highlight the need for focused interventions to address potential risks and promote healthier digital habits among this population.

A Selective Counseling Program for Reducing Fear of Missing Out (FoMO) and Its Impact on Decreasing Social Anxiety and Internet Gaming Disorder among Adolescent Girls in Bisha Governorate

This study aimed to investigate the effectiveness of a selective counseling program in reducing the Fear of Missing Out (FoMO) and its impact on decreasing social anxiety (SA) and Internet gaming disorder (IGD) among adolescent girls in Bisha Governorate. The research sample consisted of 22 students from the second grade of high school in Bisha Governorate schools. They were divided into two groups: 11 students representing the control group and 11 students representing the experimental group, who scored highest on the FoMO scale (developed by the researchers) and SA scale (Abdel-Rahman, &amp; Abdel-Maqsoud, 1998), and IGD scale (developed by the researchers). The verbal intelligence test for secondary and university stage (Gaber, &amp; Omar, 2007) was also administered. The selective counseling program (developed by the researchers) was implemented, and the Statistical Package for the Social Sciences (SPSS) version 25 was used for data analysis. The results demonstrated the effectiveness of the selective program in reducing the FoMO, social anxiety, and IGD among the experimental research sample. Additionally, the results showed that there were no statistically significant differences between the mean scores of the pre- and post-test for FoMO scale, SA scale, and IGD scale.

Impulsivity and aggression as risk factors for internet gaming disorder among university students

Internet gaming addiction is a global problem, especially among young individuals. Exhibiting characteristics similar to other addictions, Internet Gaming Disorder (IGD) is linked to adverse mental health outcomes. Identified as risk factors for dependence behaviors, the association of impulsivity and aggression with IGD is relatively under-researched in the student population. The present sample of 350 university students (Mage = 21.30 years, SDage = 4.96 years) from Najran university in Saudi Arabia completed an online questionnaire that included the Internet Gaming Disorder Scale–Short-Form (IGDS9-SF), the Buss–Perry Aggression Questionnaire-Short Form, and the Barratt Impulsiveness Scale (BIS-15). Results indicated that impulsivity and aggression were positively associated with IGD severity and both personality traits explained 34.6% of the variance in IGD scores. Further bivariate analyses suggested that individuals spending 7 or more hours on internet gaming were more likely to exhibit high impulsivity and aggression, and had a relatively higher severity of IGD. These results suggest that individuals with these personality traits may be more vulnerable to developing an addiction to internet gaming. These findings need to be confirmed in future more robust studies; however, this exploratory study provides insights for potential programs to prevent IGD among young individuals.

Prevalence and predictors of social anxiety disorders among Malaysian secondary school students during the COVID-19 pandemic: Exploring the influence of internet gaming disorder and impulsivity.

This study aimed to investigate the prevalence of social anxiety disorder (SAD) among Malaysian secondary school students during the COVID-19 pandemic and to explore its correlations with demographic variables, impulsivity behavior, and internet gaming disorder (IGD). A total of 1574 participants from 12 government secondary schools across five Malaysian states, comprising 569 males and 1005 females, completed an online questionnaire containing validated Malay versions of the Social Interaction Anxiety Scale, Barratt Impulsiveness Scale, and Internet Gaming Disorder Scale - Short Form. The findings revealed a notable SAD prevalence rate of 40.53% among Malaysian adolescents. Logistic regression analysis unveiled significant associations between SAD and factors such as attention impulsiveness (OR = 2.58, p < .001), motor impulsiveness (OR = 1.47, p = .03), female gender (OR = 2, p < .001), Malay ethnicity, and IGD (OR = 1.08, p < .001). In conclusion, this study provides valuable insights into the extent of social anxiety experienced by Malaysian secondary school students during the pandemic, shedding light on the demographic and psychosocial factors linked to its emergence. Furthermore, the research underscores a robust link between IGD and SAD, emphasizing the need for comprehensive interventions addressing both issues concurrently. By recognizing the multifaceted nature of these associations, future interventions can be tailored to provide holistic support for adolescents' mental well-being.

Academic Performance and Internet Gaming Disorder: A Cross-Sectional Study

In recent years, Internet Gaming Disorder (IGD) has become a global issue as people have gotten overly enthusiastic about playing excessive internet games. Adolescents who play excessively on the internet develop IGD, which impacts their academic performance. In the present study, a comparative research design has opted to explore the impact of IGD across gender, academic performance, and adolescence. A total of 357 adolescents (males = 220, females = 137) from various private schools and colleges of Rawalpindi and Islamabad were selected to obtain data on Internet Gaming Disorder Scale 9- Short Form (IGDS9-SF). The results of one-way ANOVA showed a significant main effect of IGD across gender (males &amp; females). They indicated the evidence of the significance of the main effect for the assessment of IGD with F (1,355) = 11.36, p=.001. The results of two-way mixed factorial ANCOVA showed that there is a significant main effect for IGD across Academic Performance Groups (A, B, C, D &amp; F grades). They indicated the evidence of the significance of the main effect for the assessment of IGD with (F (4,352) = [9.806], p&lt;.001). Further results of two-way mixed factorial ANCOVA showed that there is a significant main effect for IGD across Groups (early &amp; late adolescence). They indicated the evidence of the significance of the main effect for the assessment of IGD with F (1,355) = 6.594, p= .011. These findings may aid in the development of a policy for the efficient use of the Internet, as well as the development of awareness programs to educate parents about the harmful use of Internet games, as well as the identification and formulation of intervention plans for adolescents suffering from IGD symptoms and performing poorly in school.

Social, Behavioral, and Academic Ramifications of Video Game Playing in College

The purpose of this research project is to determine whether video game usage influences the psychological well-being of college students. This project seeks to understand technology usage habits among students and whether this affects school performance. Previous research suggests video games may be used to treat psychological issues such as anxiety. Self-report studies note video games were helpful in certain populations in coping with stress, developing positive social behaviors, and improving cognitive abilities (Carras et al., 2018; Nuyens et al., 2019; Schuurmans et al., 2018;). Since psychological well-being is a crucial factor in academic performance (Carton &amp; Goodboy, 2015; Punia &amp; Malaviya, 2015), the current study will examine potential relationships between gaming and college GPAs. Poor habits related to technological usage may lead to negative mental health outcomes. A survey examining these factors was completed by college students at Texas Woman’s University. The survey was composed of questions from the Internet Gaming Disorder Scale, Psychological Wellbeing Scale, and Boundary Management Subscale. Data was tested using ANOVAs, a Tukey HSD test as a post hoc test, and Eta squared. The results of the data found gaming tendencies were not significantly associated with GPA but were associated with negative mental health outcomes and increased issues with technology boundary management. The study has marked limitations due to the lack of non-gaming survey participants and most respondents identifying as female. These findings may be useful for clinicians in treating addictive gaming tendencies. Future research should examine more diverse student populations.

Problematic Gaming at a Crossroad: Exploring the Interplay Between Internet Gaming Disorder, Toxic Attitudes, and Empathy in Digital Entertainment

It is becoming more common to use Internet Gaming Disorder (IGD) to measure problematic gaming in online environments. However, there is limited data examining the role of empathy and toxicity in IGD. In addition, little attention has been given to the role of the social element of online gaming communities and its influence on these factors. This article aims to address this gap by presenting the results of a cross-sectional study involving 567 online players who completed an online survey about their gaming habits. More specifically, participants were recruited from four different game communities and asked to complete the Internet Gaming Disorder Scale—Short Form, a toxicity-related questionnaire, and the Interpersonal Reactivity Index. Comparisons between the four game communities were also explored. Findings pointed at significant associations between toxicity, empathy, game community, and IGD, suggesting additional research opportunities and counter strategies for preventing negative experiences with online gaming.

Factor structure and psychometric properties of an Arabic version of the Internet Gaming Disorder Scale, short form (IGDS-SF9).

In its most recent edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM), the American Psychological Association recognized that internet gaming disorder is a psychological condition and provides nine criteria for its diagnosis, and the Internet Gaming Disorder Scale, short form (IGDS-SF9) was developed to assess individuals. To develop and investigate the psychometric properties of an Arabic version of IGDS-SF9. A five-stage translation and verification process produced an Arabic version of IGDS-SF9, and a study was conducted using a sample of 410 respondents (45.6% females, mean age = 17.6, SD = 1.56) to assess its psychometric properties. Respondents completed the Arabic version, the Smartphone Addiction Scale, the Smartphone Application-Based Addiction Scale, the Hospital Anxiety and Depression Scale, as well as a demographic survey. Exploratory and confirmatory factor analyses, measurement invariance, item response theory, convergent, concurrent, criterion validity, and internal consistency reliability and test-retest reliability were employed to validate the scale. The exploratory factor analysis suggested the scale's unidimensional structure; the confirmatory factor analysis exhibited good model fit and factor loadings. Measurement invariance, and concurrent, convergent, and criterion validity were established, resulting in good internal consistency and test-retest reliability for the scale. The Arabic version of IGDS-SF9 is a valid and reliable measure for research and diagnosis in Arabic-speaking countries.

Validation of the Thai Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) among young adults

BackgroundThe Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) is a consistent and comprehensive instrument to assess symptoms of specific internet-use disorders including those related to gaming, shopping, pornography use disorder, social networks use and gambling considering criteria in the eleventh revision of the International Classification of Diseases (ICD-11). However, to date, there is little evidence supporting instruments assessing major types of specific internet use disorders in Thailand. The aim of this present study was to assess the psychometric properties of the ACSID-11 among Thai young adults.MethodsA total of 612 participants were recruited. A confirmatory factor analysis (CFA) examined construct validity of the ACSID-11. Cronbach’s α and McDonald’s ω were used to assess reliability of the ACSID-11. Pearson correlations examined relationships between ACSID-11 domains and Internet Gaming Disorder Scale—Short Form (IGDS9-SF) scores.ResultsThe CFA supported validity of the Thai version of the ACSID-11 and a four-factor structure. Specific domains of the Thai ACSID-11, particularly gaming, were positively and significantly correlated with IGDS9-SF scores.ConclusionsData indicate that the Thai version of the ACSID-11 is a valid and reliable instrument to assess major types of specific internet use disorders. Additional studies are needed to further examine the validity and reliability of the Thai ACSID-11.

Adverse childhood experiences predict internet gaming disorder in university students: the mediating role of resilience.

To investigate the relationship between adverse childhood experiences and internet gaming disorder (IGD) and the mediating role of resilience in the relationship between these two factors. The adverse childhood experience scale, resilience scale and IGD Scale were administered to 9349 university students. Correlations and mediating effects were calculated among these scores. After controlling for sex and age, significant correlations among adverse childhood experiences, resilience and IGD were observed; resilience was a partial mediator variable in the relationship between adverse childhood experiences and IGD. The more adverse childhood experiences an individual has, the less their mental toughness and the greater their tendency to become addicted to internet games. Adverse childhood experiences can effectively predict IGD, and the risk of becoming addicted to the internet can be decreased by increasing one's mental toughness.

Prevalence of internet gaming addiction and its association with sleep quality in medical students.

In Asia, there are approximately 2.3 billion internet users. Addiction to internet gaming takes a multifaceted toll on an individual's physical and mental well-being, casting a long shadow over their daily endeavors and also their sleep cycle. To study the prevalence of internet gaming addiction and how it affects sleep quality in medical students. A cross-sectional study was performed with a sample size (n = 112) in the Government Medical College, Datia (M.P.), and data were collected using a semi-structured proforma including the Internet Gaming Disorder Scale and Mini Sleep Questionnaire in the study population. In the study population with age group 18-28 years (mean age: 21 ± 1.7 years), the majority of them belong to the Hindu religion (91.1%), nuclear family (66.1%), and urban community (75.9%). Most students (n = 74) had mild to moderate sleep difficulty related to internet gaming addiction, that is, 65.1%. The most common response was "sometimes" on the Internet Gaming Disorder Scale. A significant association was observed between gaming disorder and parameters of sleep mainly in waking up too early, daytime sleepiness, snoring, feeling tired, and headache upon waking up with gaming disorder. Among medical students, gaming addiction is significantly associated with poor sleep quality. Steps need to be taken to promote healthy internet use to improve sleep quality and mitigate negative effects to avoid long-term health impacts.

INTERNET GAMING DISORDER AMONG INDONESIAN MUSLIM UNDERGRADUATE STUDENTS

Internet Gaming Disorder Scale was originally developed to measure Internet Gaming Disorder (IGD) based on the nine criteria proposed by the Diagnostic and Statistical Manual of Mental Disorders, 5th ed. (DSM-5). Until recently, there is no result of prevalence of internet gaming disorder among Indonesian Muslim undergraduate students. The objective of this study is to investigate the prevalence of Internet Gaming Disorder among Indonesian Muslim undergraduate students and to explore what are the factors that cause and have effects of IGD in Indonesian Muslim undergraduate students. A case study approach was utilized to gain insight into the experience of six Muslim undergraduate students in Batusangkar city. Data was collected through semi-structured interviews, and analyzed through coding, categorization, and identification of key data concepts. The findings indicate that the intensity of several game use can influence the prevalence of internet gaming disorder among Muslim undergraduate students. Disrupted conduct, social withdrawal, aggression and poor academic performance are among the many problems that results from excessive gaming use. This research contributes to ongoing discussions about internet gaming disorder and its impact on students’ both psychological and physical wellbeing or health in the field of Islamic education.

Association of internet gaming disorder with impulsivity: role of risk preferences

BackgroundInternet gaming disorder (IGD) is a formal mental disorder leading to personal and social impairment. Although it shares similar physical and psychosocial effects to substance use disorder, the psychological mechanisms underlying IGD remain unclear, although several researches have made significant contributions to its understanding. This study aims to elucidate the correlation between IGD, impulsive personality and risk preference of medical college students in China, from a questionnaire-based investigation.MethodsBased on the cluster random sampling method, a questionnaire survey was conducted among medical college students in Northern Anhui, China from September 3 to October 27, 2020. The questionnaires included the Internet Gaming Disorder Scale (IGD-20), Chinese revised of Barratt Impulsiveness Scale Version 11 (BIS-11), and risk appetite index (RPI). Perform independent sample t-tests, analysis of variance (ANOVA), correlation analysis, and moderating effect analysis using SPSS 23.0. P < 0. 05 is considered statistically significant.Results624 participants completed the survey, including 257 males (41.19%) and 367 females (58.81%). All participants were between 18 and 24 years. We found that in IGD and its six different dimensions and RPI, males scored significantly higher than females. Additionally, our finding revealed there is statistical significance in IGD and impulsiveness between gaming group with game time greater than or equal to 4 h and non-gaming group. The IGD and its six different dimensions, among which all except for mood modification are positively correlated with impulsiveness and RPI. Mediating effects indicate that RPI plays a partial mediating role between motor impulsiveness and IGD.ConclusionThe findings shows that there is a certain relationship between impulsivity and RPI, as well as IGD and its dimensions. RPI may be a mediator between impulsivity and IGD, and men have higher IGD. The findings supported the compensatory hypothesis. These findings may contribute to further research and development of intervention and prevention measures for IGD.

Dietary Habits and Gaming Behaviors of Portuguese and Brazilian Esports Players.

As the esports industry grows, marketing campaigns for fast food, soft drinks, alcoholic and energy drinks, and dietary supplements at related events intensify. Portuguese and Brazilian esports players' dietary patterns remain unexplored. This study aimed to characterize the dietary and gaming habits of esports players. We applied an anonymous, open online survey to a convenience sample of esports players that included the PREDIMED and the Internet Gaming Disorder Scale. The survey was shared through email and social media platforms, including Facebook, Twitter, Instagram, Discord, WhatsApp, and Twitch. The sample (n = 579) was predominantly male (91.4%), averaged 26.1 (SD = 7.0) years, and 25.9 (SD = 5.5) kg/m2. Most reported a weak (53.7%) adherence to the Mediterranean diet. Almost a third (32.3%) consumed dietary supplements. Our sample presented a low adhesion to the Mediterranean dietary pattern, low consumption of fruit and vegetables, and high consumption of fast food, red and processed meat, soft drinks, and dietary supplements, including caffeine-based supplements. Dietary supplement consumption was related to a higher adhesion to the Mediterranean diet, and a higher level of professionalization and internet gaming disorder correlated with a lower adhesion. In conclusion, we infer that Portuguese and Brazilian esports players follow an unbalanced diet.

Network structures of internet gaming disorder and gaming disorder: Symptom operationalization causes variation.

From 2022, the International Classification of Diseases, eleventh edition (ICD-11) includes the first mental disorder based on digital technology, "gaming disorder," which was previously suggested as a condition for further examination in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). In this cross-sectional study, we provide the first large-scale network analysis of various symptom structures for these constructs to understand the complex interconnections between their proposed symptoms. Culturally diverse samples of 2,846 digital game players (M = 25.3 years) and 746 esports players (M = 23.5 years) were recruited. A network approach was applied to explore a multiverse of gaming disorder symptom structures, effects of item operationalization, and possible external moderators. Gaming disorder was measured using the Internet Gaming Disorder Scale 9-Short Form (IGDS9-SF), Gaming Disorder Test, and several items borrowed from Chinese Internet Gaming Disorder Scale, Personal Internet Gaming Disorder Evaluation-9, and Clinical Video game Addiction Test 2.0 scales. Two symptoms (loss of control and continued use despite problems) present in both, the DSM-5 and ICD-11, were systematically central to most of the analyzed networks. Alternative operationalizations of single items systematically caused significant network differences. Networks were invariant across groups of play style, age, gender, gaming time, and most of the psychosocial characteristics. Our results caution practitioners and researchers when studying and interpreting gaming disorder symptoms. The data indicate that even minor operational changes in symptoms can lead to significant network-level changes, thus highlighting the need for careful wording.

Online Behavioral Addictions Among Adolescents Before and After the COVID-19 Pandemic.

Background The COVID-19 pandemic changed people's lives and created a "new normal." It threatened individuals' mental health owing to reduced physical activity and social interaction, excessive indoor time, financial hardship, and insecurity. Moreover, the risk of online behavioral addiction increased in the general population, particularly among adolescents. The present study examined the differences between the pre-and post-pandemic periods regarding online behavioral addictions in adolescents. Methods The pre-pandemic data were obtained from 175 adolescents (August 2019 to February 2020) (T1). An online survey was sent to these participants to obtain the post-pandemic data (March to September 2022) (T2). Seventy participants completed the online survey (response rate: 40%). The participants completed the Smartphone Addiction Scale (SAS), the Internet Gaming Disorder Scale 9-Short Form (IGDS9-SF), and the Social Media Disorder Scale-Short Form (SMDS-SF) both before and after the pandemic. Results Before the pandemic, females had significantly higher SMDS-SF scores compared to males (p = 0.005). On the other hand, males had higher IGDS9-SF scores than females before the pandemic (p<.001). Individuals with attention deficit hyperactivity disorder (ADHD) had higher IGDS9-SF scores before the pandemic than those with depressive disorders or other diagnoses (p = 0.004). However, the primary diagnosis was not related to pre-pandemic SAS and SMDS-SF scores. Lastly, there was no significant difference in IGDS9-SF (p = 0.151), SMDS-SF (p = 0.200), or SAS scores (p = 0.413) between pre-pandemic and post-pandemic scores. Conclusion Although the current study did not support this view, in emotionally challenging times, people may spend more time on online activities, which can lead to behavioral addiction. It is important for parents to monitor their children's online activities and provide guidance. More research is needed to compare online behavioral addictions before and after the pandemic.

Digital Phenotypes for Early Detection of Internet Gaming Disorder in Adolescent Students: Explorative Data-Driven Study.

Limited awareness, social stigma, and access to mental health professionals hinder early detection and intervention of internet gaming disorder (IGD), which has emerged as a significant concern among young individuals. Prevalence estimates vary between 0.7% and 15.6%, and its recognition in the International Classification of Diseases, 11th Revision and Diagnostic and Statistical Manual of Mental Disorders, 5th Edition underscores its impact on academic functioning, social isolation, and mental health challenges. This study aimed to uncover digital phenotypes for the early detection of IGD among adolescents in learning settings. By leveraging sensor data collected from student tablets, the overarching objective is to incorporate these digital indicators into daily school activities to establish these markers as a mental health screening tool, facilitating the early identification and intervention for IGD cases. A total of 168 voluntary participants were engaged, consisting of 85 students with IGD and 83 students without IGD. There were 53% (89/168) female and 47% (79/168) male individuals, all within the age range of 13-14 years. The individual students learned their Korean literature and mathematics lessons on their personal tablets, with sensor data being automatically collected. Multiple regression with bootstrapping and multivariate ANOVA were used, prioritizing interpretability over predictability, for cross-validation purposes. A negative correlation between IGD Scale (IGDS) scores and learning outcomes emerged (r166=-0.15; P=.047), suggesting that higher IGDS scores were associated with lower learning outcomes. Multiple regression identified 5 key indicators linked to IGD, explaining 23% of the IGDS score variance: stroke acceleration (β=.33; P<.001), time interval between keys (β=-0.26; P=.01), word spacing (β=-0.25; P<.001), deletion (β=-0.24; P<.001), and horizontal length of strokes (β=-0.21; P=.02). Multivariate ANOVA cross-validated these findings, revealing significant differences in digital phenotypes between potential IGD and non-IGD groups. The average effect size, measured by Cohen d, across the indicators was 0.40, indicating a moderate effect. Notable distinctions included faster stroke acceleration (Cohen d=0.68; P=<.001), reduced word spacing (Cohen d=.57; P=<.001), decreased deletion behavior (Cohen d=0.33; P=.04), and longer horizontal strokes (Cohen d=0.34; P=.03) in students with potential IGD compared to their counterparts without IGD. The aggregated findings show a negative correlation between IGD and learning performance, highlighting the effectiveness of digital markers in detecting IGD. This underscores the importance of digital phenotyping in advancing mental health care within educational settings. As schools adopt a 1-device-per-student framework, digital phenotyping emerges as a promising early detection method for IGD. This shift could transform clinical approaches from reactive to proactive measures.
