Measurement and Conceptualization of Gaming Disorder According to the World Health Organization Framework: the Development of the Gaming Disorder Test

Gaming time and impulsivity as independent yet complementary predictors of gaming disorder risk

Prolonged gaming time, along with increased impulsivity-a key element of poor self-regulation-has been identified as linked to gaming disorder. Despite existing studies in this field, the relationship between impulsivity and gaming time remains poorly understood. The present study explored the connections between impulsivity, measured both by self-report and behavioral assessments, gaming time and gaming disorder within a cohort of 82 participants. While gaming time exhibited a significant correlation with gaming disorder, only self-reported measures of impulsivity and one behavioral metric showed a correlation with gaming disorder. Self-report measures of impulsivity exclusively predicted gaming disorder when included in a regression model with gaming time. The interaction between gaming time and impulsivity, aside from one behavioral metric was deemed insignificant. These findings suggest that impulsivity and gaming time, although associated with gaming disorder risk, are independent variables. Further research should aim to clarify these relationships and explore potential interventions targeting both DGI and impulsivity to mitigate gaming disorder risk.

The competitive esports physiological, affective, and video dataset

Esports refers to competitive video gaming where individuals compete against each other in organized tournaments for prize money. Here, we present the Competitive Esports Physiological, Affective, and Video (CEPAV) dataset, in which 300 male Counter Strike: Global Offensive gamers participated in a study aimed at optimizing affect during esports tournament1. The CEPAV dataset includes (1) physiological data, capturing the player's cardiovascular responses from before, during, and after over 3000 CS: GO matches; (2) self-reported affective data, detailing the affective states experienced before gameplay; and (3) video data, providing a visual record of 552 in-laboratory gaming sessions. We also collected (affect-related) individual differences measures (e.g., well-being, ill-being) across six weeks in three waves. The self-reported affective data also includes gamers' natural language descriptions of gaming affective situations. The CEPAV dataset provides a comprehensive resource for researchers and analysts seeking to understand the complex interplay of physiological, affective, and behavioral factors in esports and other performance contexts.

Use of 4 Open-Ended Text Responses to Help Identify People at Risk of Gaming Disorder: Preregistered Development and Usability Study Using Natural Language Processing

BACKGROUND

Words are a natural way to describe mental states in humans, while numerical values are a convenient and effective way to carry out quantitative psychological research. With the growing interest of researchers in gaming disorder, the number of screening tools is growing. However, they all require self-quantification of mental states. The rapid development of natural language processing creates an opportunity to supplement traditional rating scales with a question-based computational language assessment approach that gives a deeper understanding of the studied phenomenon without losing the rigor of quantitative data analysis.

OBJECTIVE

The aim of the study was to investigate whether transformer-based language model analysis of text responses from active gamers is a potential supplement to traditional rating scales. We compared a tool consisting of 4 open-ended questions formulated based on the clinician's intuition (not directly related to any existing rating scales for measuring gaming disorders) with the results of one of the commonly used rating scales.

METHODS

Participants recruited using an online panel were asked to answer the Word-Based Gaming Disorder Test, consisting of 4 open-ended questions about gaming. Subsequently, they completed a closed-ended Gaming Disorders Test based on a numerical scale. Of the initial 522 responses collected, we removed a total of 105 due to 1 of 3 criteria (suspiciously low survey completion time, providing nonrelevant or incomplete responses). Final analyses were conducted on the responses of 417 participants. The responses to the open-ended questions were vectorized using HerBERT, a large language model based on Google's Bidirectional Encoder Representations from Transformers (BERT). Last, a machine learning model, specifically ridge regression, was used to predict the scores of the Gaming Disorder Test based on the features of the vectorized open-ended responses.

RESULTS

The Pearson correlation between the observable scores from the Gaming Disorder test and the predictions made by the model was 0.476 when using the answers of the 4 respondents as features. When using only 1 of the 4 text responses, the correlation ranged from 0.274 to 0.406.

CONCLUSIONS

Short open responses analyzed using natural language processing can contribute to a deeper understanding of gaming disorder at no additional cost in time. The obtained results confirmed 2 of 3 preregistered hypotheses. The written statements analyzed using the results of the model correlated with the rating scale. Furthermore, the inclusion in the model of data from more responses that take into account different perspectives on gaming improved the performance of the model. However, there is room for improvement, especially in terms of supplementing the questions with content that corresponds more directly to the definition of gaming disorder.

The TikTok Addiction Scale: Development and validation

Background

There is an absence of valid and specific psychometric tools to assess TikTok addiction. Considering that the use of TikTok is increasing rapidly and the fact that TikTok addiction may be a different form of social media addiction, there is an urge for a valid tool to measure TikTok addiction.

Objective

To develop and validate a tool to measure TikTok addiction.

Methods

First, we performed an extensive literature review to create a pool of items to measure TikTok addiction. Then, we employed a panel of experts from different backgrounds to examine the content validity of the initial set of items. We examined face validity by performing cognitive interviews with TikTok users and calculating the item-level face validity index. Our study population included 429 adults who have been TikTok users for at least the last 12 months. We employed exploratory and confirmatory factor analysis to examine the construct validity of the TikTok Addiction Scale (TTAS). We examined the concurrent validity by using the Bergen Social Media Addiction Scale (BSMAS), the Patient Health Questionnaire-4 (PHQ-4), and the Big Five Inventory-10 (BFI-10). We used Cronbach's alpha, McDonald's Omega, Cohen's kappa, and intraclass correlation coefficient to examine reliability.

Results

We found that the TTAS is a six-factor 15-item scale with robust psychometric properties. Factor analysis revealed a six-factor structure, (1) salience, (2) mood modification, (3) tolerance, (4) withdrawal symptoms, (5) conflict, and (6) relapse, which accounted for 80.70% of the total variance. The concurrent validity of the TTAS was excellent since we found significant correlations between TTAS and BSMAS, PHQ-4, and BFI-10. Cronbach's alpha and McDonald's Omega for the TTAS were 0.911 and 0.914, respectively.

Conclusion

The TTAS appears to be a short, easy-to-use, and valid scale to measure TikTok addiction. Considering the limitations of our study, we recommend the translation and validation of the TTAS in other languages and populations to further examine the validity of the scale.

Mokken scale analysis of the Internet Gaming Disorder Scale-Short-Form and the Gaming Disorder Test

In recent years, research on disordered gaming has grown substantially with researchers developing different psychometric tools for assessing it. Two of the most prominent assessment tools are the Internet Gaming Disorder Scale-Short-Form (IGDS9-SF) and the Gaming Disorder Test (GDT), which evaluate disordered gaming under the American Psychiatric Association (APA) and the World Health Organization (WHO) frameworks, respectively. The main aim of this study was to assess and compare the scalability, reliability, and validity of both scales to determine if they effectively assess disordered gaming in a normative sample, through the Mokken Scale Analysis (MSA). A sample of 605 participants (42.31 % female, meanage = 23.98 years, SD = 9.21 years) was recruited for the present study. Results showed that both the IGDS9-SF and GDT were unidimensional, with all items presenting latent monotonicity fitting in the Monotone Homogeneity Model (MHM). Item characteristic curves did not intersect and presented with adequate fit in the Double Monotonicity Model (DMM). These findings further support the psychometric adequacy of the IGDS9-SF and GDT, attesting to their suitability to assess disordered gaming.

Scoping review of withdrawal's role in contemporary gaming disorder research: Conceptualizations and operationalizations

The global gaming community now exceeds 3 billion players, prompting increased attention from social and medical sciences regarding gaming-related disorders. Internet Gaming Disorder (IGD) was incorporated into DSM-5 in 2013, and Gaming Disorder (GD) found its place in ICD-11 in 2019. A contentious criterion in IGD, not present in GD, revolves around withdrawal symptoms. This paper offers a theoretical foundation on gaming withdrawal symptoms in gaming-related disorders and conducts a scoping review of withdrawal operationalization and conceptualization in 40 selected studies, following PRISMA-ScR guidelines. Most studies employed a correlation framework, relying on convenience samples and self-assessment questionnaires. A smaller portion focused on clinical samples and case studies. Withdrawal was predominantly conceptualized in terms of affective components, with less emphasis on behavioural, cognitive, physical, or neurological aspects. The prevailing terminology for gaming-related disorders was IGD, with only three studies referencing GD as defined in ICD-11. Notably, just six experimental studies included abstinence control. We advocate for an expansion of research on withdrawal symptoms, particularly through experimental studies that implement abstinence within experimental groups and offer alternative operationalizations beyond dominant self-assessment measures.

Reliability generalization Meta-Analysis and psychometric review of the Gaming Disorder test (GDT): Evaluating internal consistency

Gaming disorder (GD) is a growing public health issue requiring reliable screening and diagnostic tools. A commonly used tool for assessing GD is the Gaming Disorder Test (GDT). The GDT assesses GD based on International Classification of Diseases 11th Revision (ICD-11) criteria; however, its psychometric testing has been conducted across studies but yet snythesized. This meta-analysis aimed to synthesize psychometric data regarding the GDT globally. Adhering to pre-registration, a comprehensive search across databases identified 17 eligible studies (n=22,000) in 14 languages reporting on the psychometric properties of the GDT, especially its Cronbach's alpha. The pooled Cronbach's alpha was 0.86 (95% CI: 0.83-0.89), indicating excellent internal consistency. Although significant heterogeneity was observed (I2= 98.54%), prediction intervals suggested true outcomes likely shared a positive direction. No moderating effects were found regarding sample characteristics, study quality, or geographical location. The meta-analysis provides robust and quantitative evidence supporting the internal consistency of the GDT across diverse populations. Moreover, qualitative synthesis indicates that the GDT has strong psychometric properties without risk of bias across the analyzed studies, indicating the GDT's ability to assess GD globally. However, the heterogeneity suggests cautious interpretation of the reliability estimates.

Does gaming keep subjects awake?: Subjective and objective sleep parameters following gaming in comparison to a passive control

OBJECTIVES

Gaming is a global phenomenon often associated with impaired health and sleep patterns. Although the research activities are growing, the evidence to date is rare due to the various gaming titles and inconsistent study designs. Thus, this study aimed to examine the impact of excessive gaming in the evening on subjective as well as objective sleep parameters by focusing on specific game titles and assessing several evenings/nights using a mixed-methods approach.

METHODS

A total of 33 experienced young male adults (23.00 ± 3.53 years old, ranked players in League of Legends or Counter-Strike: Global Offensive) took part. The individuals' sleep parameters were assessed via diary and actigraphy. In randomized order, one week apart and for a duration of 120 min each, two study evenings were spent gaming, while the other two evenings were spent without digital media and gaming, but instead watching a nature documentary.

RESULTS

No significant difference between the conditions were found (p > 0.05) in either the sleep duration nor the sleep quality. Daytime sleepiness was significantly increased after watching the documentary movie, when compared to gaming (p < 0.001).

CONCLUSIONS

These results indicate that, one the one hand, the gaming activity leads to higher arousal and alertness as it requires concentration and dedication. On the other hand, this impact seems only short-term and does not necessarily affect sleep patterns. Future studies are needed to gain deeper insights, especially regarding the long-term health effects of gaming.

Role models in gaming: Wishful identification and maladaptive daydreaming mediate the association between desire for fame and game engagement

BACKGROUND

The popularity of video games has considerably increased in recent years, with approximately 3.24 billion players worldwide in 2021. Empirical evidence suggests that the quality of engagement in video games can determine whether a gaming activity is associated with psychological distress (i.e., problematic gaming) or self-enhancing outcomes (i.e., esports career pursuits). This study investigates the role of influential gaming role models and other external factors relating to fame appeal in gamers' different ways of engagement.

METHODS

A total of 803 adolescent and adult gamers (89.29 % male, Mage = 24.90 years, SD = 6.13) were recruited through an online questionnaire.

RESULTS

A path analysis was constructed demonstrating that wishful identification partially mediated the relationship between desire for fame and esports career planning. Moreover, maladaptive daydreaming fully mediated the association between desire for fame and gaming disorder symptoms. Wishful identification with gaming role models predicted both esports career planning and gaming disorder symptoms.

CONCLUSIONS

The findings shed light on the importance of considering the role of gaming role models in predicting healthy and problematic gaming patterns.

The gaming disorder test and gaming disorder scale for adolescents: translation and validation among Vietnamese young adults

BACKGROUND

Previous studies have shown that the Gaming Disorder Test (GDT) and Gaming Disorder Scale for Adolescents (GADIS-A) have promising validity and reliability when assessing symptoms of gaming disorder among young adults. However, validity and reliability properties of the two scales have not been established among a Vietnamese population.

OBJECTIVE

The present study translated the GDT and GADIS-A into Vietnamese and examined their factor structures, measurement invariance, convergent validity, concurrent validity, and divergent validity among university students.

METHODS

A total of 610 young adults (mean age = 21.09 years; 63.4% females) were recruited using convenience sampling and who completed a paper-and-pencil survey between April and June 2023. All participants completed a demographic questionnaire, GDT, GADIS-A, and six standardized scales related to gaming disorder, social media addiction, smartphone addiction, and psychological distress. Confirmatory factor analysis (CFA), internal consistency testing, and Pearson's correlations were performed.

RESULTS

CFA showed that the GDT had a one-factor structure and the GADIS-A had a two-factor structure. The internal consistency was excellent for both scales among this population. Moreover, both GDT and GADIS-A showed convergent, concurrent, and divergent validity with other standardized scales.

CONCLUSION

The Vietnamese versions of the GDT and GADIS-A have good psychometrics, which may be utilized in future research regarding gaming disorder among Vietnamese populations.

High immersion/escapism motivation makes gaming disorder risk less dependent of playtime among highly engaged male gamers

In the realm of gaming-related concerns, the relationship between gaming time (GT) and gaming disorder (GD) remains an intriguing and complex subject. Although increased GT is not a reliable predictor of GD risk, the circumstances under which this relationship strengthens or weakens remain relatively unknown. This study explores the roles of immersion/escapism motive (IEM) and GT in the context of GD among highly engaged gamers (N = 294), each dedicating a minimum of 20 hours weekly to gaming. The findings confirm that IEM significantly moderates the relationship between GT and GD in the male sample. Specifically, low and moderate levels of IEM result in a stronger relationship between GT and GD. In the case of women, the effect was not significant. These findings suggest the importance of comprehensive assessments of gaming motivations when addressing gaming-related issues, particularly in GD research. Moreover, they emphasize the value of adopting a complex approach to comprehending the development of problematic gaming behaviors.

Big five personality traits, gaming motives, and regular and disordered gaming: A cross-national examination among college student gamers in seven countries

INTRODUCTION

Previous research has shown that personality traits and gaming motives are important predictors for explaining regular and disordered gaming. However, the mediating role of gaming motives in the relation between personality traits and video game outcomes (e.g., time spent gaming or disordered gaming) has been scarcely studied and limited cross-national studies have addressed this issue. The present study aimed to examine the direct and indirect effects of the Big Five personality traits on weekly gaming and disordered gaming via gaming motives across seven countries.

METHOD

3540 college student gamers (59.5% women) from the U.S., Canada, Spain, Argentina, Uruguay, South Africa and England completed the online survey. Structural equation modeling was conducted to test models. Multigroup models were employed to test model invariance across countries.

RESULTS

Significant, albeit weak, relations were found between personality traits and gaming outcomes, and were mediated mostly by coping motives in predicting disordered gaming, and by social interaction and recreation (to a lesser extent) motives in predicting weekly gaming. Some minor, yet significant, differences across countries appeared and are discussed in detail.

DISCUSSION

The present findings indicate that the differential interrelations between personality traits, gaming motives, and video gaming outcomes may be generalized in college students across countries.

Effectiveness and Acceptability of Cognitive Behavioral Therapy and Family Therapy for Gaming Disorder: Protocol for a Nonrandomized Intervention Study of a Novel Psychological Treatment

Towards an automated approach for understanding problematic gaming

Introduction

Video games have become increasingly popular worldwide, attracting billions of gamers across diverse demographics. While studies have highlighted their potential benefits, concerns about problematic gaming behaviors have also emerged. Conditions such as Internet Gaming Disorder (IGD) have been recognized by major health organizations, necessitating accurate diagnostic tools. However, existing methods, primarily reliant on self-report questionnaires, face challenges in accuracy and consistency. This paper proposes a novel technological approach to provide gaming behavior indicators, aiming to offer precise insights into gamer behavior and emotion regulation.

Methods

To attain this objective, we investigate quantifiable gaming behavior metrics using automated, unobtrusive, and easily accessible methods. Our approach encompasses the analysis of behavioral telemetry data collected from online gaming platforms and incorporates automated extraction of gamer emotional states from face video recordings during gameplay. To illustrate the metrics and visualizations and demonstrate our method's application we collected data from two amateur and two professional gamers, all of whom played Counter-Strike2 on PC. Our approach offers objective insights into in-game gamer behavior, helping health professionals in the identification of patterns that may be difficult to discern through traditional assessment methods.

Results

Preliminary assessments of the proposed methodology demonstrate its potential usefulness in providing valuable insights about gaming behavior and emotion regulation. By leveraging automated data collection and visualization analysis techniques, our approach offers a more comprehensive understanding of gamer behavior, which could enhance diagnostic accuracy and inform interventions for individuals at risk of problematic gaming behaviors.

Conclusion

Our findings demonstrate the valuable insights obtainable from a tool that collects telemetry data, emotion regulation metrics, and gaming patterns. This tool, utilizing specific indicators, can support healthcare professionals in diagnosing IGD and tracking therapeutic progress, potentially addressing challenges linked to conventional IGD assessment methods. Furthermore, this initial data can provide therapists with detailed information on each player's problematic behaviors and gaming habits, enabling the development of personalized treatments tailored to individual needs. Future research endeavors will focus on refining the methodology and extending its application in clinical settings to facilitate more comprehensive diagnostic practices and tailored interventions for individuals at risk of problematic gaming behaviors.

Approach bias in individuals with Internet gaming disorder: Evidence from an event-related potential-based approach-avoid task

Individuals with Internet gaming disorder (IGD) often exhibit an approach bias towards gaming cues compared to non-gaming cues. Although previous studies suggested a positive correlation between approach bias and the severity of game use, the neuropsychological mechanisms that underpin the automatic action tendencies remain largely unexplored. The present study measured event-related potentials (ERPs) in 22 IGD and 23 healthy control (HC) participants who met the inclusion criteria, both groups conducted the Stimulus-Response Compatibility task (SRC), with their ERPs recorded during the task. Results revealed that the IGD group showed a significantly larger approach bias towards gaming cues (avoidance versus approach reaction time) compared to the HC group. The amplitude of P300 significantly increased, whereas N100 significantly decreased for game-approach compared to game-avoid for IGD compared to HC participants. The findings suggested that the enhanced integrated motivational value under compatible conditions as well as increased stimulus-response conflicts under incompatible conditions may contribute to the approach bias in IGD individuals. Further investigation on the intervention is prompted through longitudinal studies.

Going beyond video game consumption when considering Internet Gaming Disorder

BACKGROUND

Recognizing the crucial importance of understanding the impact of video games on health in today's gaming-dominated world, our study aimed to investigate the relationship between gaming time and Internet Gaming Disorder (IGD). Despite the widespread assumption that a connection exists between both, previous studies have revealed highly variable associations, highlighting significant weaknesses in establishing a robust link.

METHODS

To unravel this complex relationship, we recruited two independent samples of League of Legends players. We combined the collection of self-reported and actual gameplay data, together with assessments of mental health, personality traits, and cognitive abilities.

RESULTS

Surprisingly, none of the gaming variables demonstrated a robust and stable association with IGD, regardless of whether players spent less than or more than 30 hours per week gaming-a threshold suggested by the American Psychiatric Association as a potential indicator of disordered gaming. Notably, mental health factors, such as anxiety, depression and ADHD, emerged as the most influential predictors of IGD.

CONCLUSION

These findings, replicated across two independent samples, challenge the prevailing belief that limiting screen time alone effectively combats IGD. Instead, mental health factors play a crucial role in mitigating risks associated with gaming. Policies focusing solely on restricting screen time are insufficient in reducing the prevalence or symptoms of IGD. Rather, a comprehensive approach that considers mental health and key personality traits must be adopted to safeguard the well-being of individuals engaged in gaming.

European Portuguese Version of the Game Addiction Scale-7: Factor Structure and Psychometric Properties

INTRODUCTION

Game addiction (GA) can be described as a compulsive and excessive usage of computers or video games that causes emotional and or social problems. The current study tested the factor structure and psychometric properties of the European Portuguese Game Addiction Scale (GAS-7-PT) short version.

METHODS

The sample encompassed 375 participants, 233 women (62.1%) and 142 men (37.9%), with a mean age of 21.71 (standard deviation = 5.82) years old. Participants completed a set of self-report measures online: the GAS-7-PT, the Scale of Involvement in Video Games and the Patient Health Questionnaire-4.

RESULTS

Confirmatory factor analyses confirmed a biological sex invariant single-factor structure with a very good fit to the data. The GAS-7-PT showed good reliability and test-retest reliability. Correlations with related and unrelated measures suggested convergent validity, and partial correlation results pointed to incremental validity. Men showed significantly higher scores than women.

CONCLUSION

The GAS-7-PT is a self-report instrument with suitable psychometric properties for clinical and research contexts. The availability of a European Portuguese version confirms the GAS-7 robust consistency and allows further cross-cultural clinical research.

Insights on associations between the frequency of use of diverse social media products and social networks use disorder tendencies from a German speaking sample

OBJECTIVE

In the present work we investigate how individual differences in at least occasionally using distinct social media platforms is linked to social networks use disorder (SNUD) tendencies. A final sample of n = 2200 participants filled in the AICA-C-9 measure to get insights into individual differences in overuse of social media and participants also indicated which platforms they used at least once a month.

RESULTS

The analysis revealed a robust positive association between number of at least occasionally used social media apps and SNUD tendencies (r = .44, p < .001). Further, platforms differed in terms of their "addictive potential", if one takes associations between frequency of distinct platforms use and SNUD tendencies as a proxy for this (and of course the actual descriptive statistics of the SNUD scale for the (non-)frequent user groups of the different platforms). In this regard, at least occasionally using some platforms (here Tumblr, Twitter and TikTok) was associated with highest SNUD tendencies. Moreover, largest differences in terms of effect sizes between the occasional and non-occasional user groups regarding SNUD scores could be observed for Instagram, WhatsApp, and TikTok. The present work bases on data from a larger project investigating associations between SNUD and tobacco use disorder.

Gaming disorder test: Assessing psychometric properties, prevalence, temporal stability, and invariance using a Czech two-time-point longitudinal sample

In 2019, Gaming Disorder (GD) was acknowledged as an official diagnosis by the World Health Organization. The Gaming Disorder Test (GDT) is the most widely used tool to measure GD; however, due to its novelty, various measurement properties are still unexplored, and the number of validated language variants is still limited. The present study is the first to assess the psychometric properties of the Czech version of the GDT. Further, it focuses on its temporal prevalence and stability, gaming genre invariance, and criterion validity. A large-scale sample of adult Czech gamers collected at two points within nine months was analysed - T1 N = 5356; T2 N = 6077; longitudinal sample N = 1430. Confirmatory factor analysis (CFA), structural equation modelling (SEM), and multigroup CFA were employed to assess the measurement invariance. The study confirmed the one-factor structure of the GDT and showed that it is invariant across preferred gaming genres and the time of data collection. It showed a negative relationship with life satisfaction and a positive relationship with anxiety, even when controlling for their mutual relationships. The prevalence in the longitudinal sample was equal to or below 1.9% in each wave, but only 0.5% in the longitudinal sample (hence n = 7 participants fulfilled in both waves the criteria for GD). The study suggests that the Czech version of the GDT has good psychometric properties, including temporal stability and invariance across gaming genres, so it is suitable for the survey type and epidemiological investigation of the ICD-11's Gaming Disorder.

Applying a synergistic mindsets intervention to an esports context

Affective responses during stressful, high-stakes situations can play an important role in shaping performance. For example, feeling shaky and nervous at a job interview can undermine performance, whereas feeling excited during that same interview can optimize performance. Thus, affect regulation-the way people influence their affective responses-might play a key role in determining high-stakes outcomes. To test this idea, we adapted a synergistic mindsets intervention (SMI) (Yeager et al. 2022 Nature 607, 512-520 (doi:10.1038/s41586-022-04907-7)) to a high-stakes esports context. Our approach was motivated by the idea that (i) mindsets both about situations and one's stress responses to situations can be shaped to help optimize stress responses, and (ii) challenge versus threat stress responses will be associated with improved outcomes. After a baseline performance task, we randomly assigned gamers (n = 300) either to SMI or a control condition in which they learned brain facts. After two weeks of daily gaming, gamers competed in a cash-prize tournament. We measured affective experiences before the matches and cardiovascular responses before and throughout the matches. Contrary to predictions, gamers did not experience negative affect (including feeling stressed), thus limiting the capacity for the intervention to regulate physiological responses and optimize performance. Compared with the control participants, synergistic mindsets participants did not show greater challenge responses or improved performance outcomes. Though our adaptation of Yeager et al.'s SMI did not optimize esports performance, our findings point to important considerations regarding the suitability of an intervention such as this to different performance contexts of varying degrees of stressfulness.

Risk and protective factors for substance use and media addictive behaviors in adolescents during the COVID-19 pandemic

OBJECTIVE

This study examined the long-term effects of the COVID-19 pandemic on adolescents' substance use, digital media use, and symptoms of internet, gaming, and social media addiction.

METHOD

A nationally representative longitudinal cohort of 1665 Israeli teens and preteens, aged 9-16, completed questionnaires assessing substance use prevalence, daily screen time, symptoms of media addiction, and potential risk and protective factors. Data were collected before the pandemic (October 2019), after the second wave lockdown (November 2020), and after the fifth wave (April 2022) in Israel.

RESULTS

The analysis documented significant increases in substance use, daily screen time, and social media addiction indices over time. Gratitude, life satisfaction, positive emotions, future orientation, grit, and secure attachment emerged as significant protective factors. Sensation-seeking, negative emotions, and mental health symptoms were identified as risk factors.

CONCLUSIONS

These findings highlight the importance of educational and public mental health services in addressing the pandemic's long-term impact on the mental health and addictive behaviors of adolescents. They also emphasize the significance of enhancing protective factors and reducing risk factors to effectively mitigate substance and digital media abuse among adolescents.

Understanding Esports-related Betting and Gambling: A Systematic Review of the Literature

Esports gambling has steadily grown in popularity alongside esports itself. While research has been increasing in the field of esports-related gambling, no study has yet reviewed the relevant literature on esports gambling. The present study aimed to comprehensively review all empirical research conducted in the wider field of esports gambling. A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was undertaken using PsycINFO, PubMed, Scopus, and Web of Science databases. Only empirical studies were included and were also assessed for potential biases using the ROBUST guidelines. A total of 30 studies from eight countries were included in the review. Esports gamblers were found more likely to be young males, likely to score high on problematic gambling scales, and likely to belong to households speaking a non-English language at home in English speaking countries. Esports gamblers are a unique type of gambling population, with rare characteristics and behaviors compared to other types of gamblers. Given the limited number of studies, there is a need for further research in this field to understand these populations, as well as the need for longitudinal research.

Meta-Analysis of Internet Gaming Disorder Prevalence: Assessing the Impacts of DSM-5 and ICD-11 Diagnostic Criteria

With the inclusion of Internet gaming disorder (IGD) in both the DSM-5 and ICD-11, understanding the prevalence and diagnostic discrepancies is crucial for developing appropriate interventions. This study presents a meta-analysis of the prevalence of IGD based on two diagnostic criteria. We systematically searched the PubMed and Web of Science databases. A total of 22 studies were included in the final analysis. The analysis incorporated studies employing the DSM-5 and ICD-11 criteria and focused on the impact of various factors, including study location, sample characteristics, sample size, and quality score, on the reported prevalence rates using a random-effects model. The pooled prevalence of IGD is 6.7% (95% CI: 5.7-7.7%). The subgroup analysis indicated significant differences in the prevalence rates of IGD (DSM-5 criteria) and GD (ICD-11 criteria) (Q b = 38.46, p < 0.01). There were also significant differences in IGD prevalence rates between different scales (Q b = 54.23, p < 0.001). Our findings indicate that different diagnostic criteria and different assessment scales have a significant impact on the prevalence of IGD. This underscores the importance of adopting standardized methodologies to guide public health interventions. However, given the limited research based on ICD-11 diagnostic criteria, further investigation is necessary to determine the variations in prevalence rates of IGD under different diagnostic standards.

Investigating the interplay between gaming disorder and functional impairments in professional esports gaming

The relationship between Gaming Disorder (GD) and the experience of functional impairments has received considerable theoretical attention in the recent past and current diagnostic approaches underscore the centrality of functional impairments as a requirement for GD diagnosis. However, there is limited empirical evidence illuminating the interplay between GD and functional impairments, particularly among specific vulnerable groups. The present study seeks to bridge this gap by investigating an English-speaking sample (N = 5198) comprising an age- and gender-matched group of Professional Gamers (PG, n = 2599) and Non-Professional Gamers (NPG, n = 2599) sub-sampled from a larger sample of 192,260 individuals. The results revealed that PG were at a greater risk for GD compared to NPG as the prevalence rate of GD among PG (3.31%) was significantly higher and almost doubled that of NPG (1.73%), with PG further exhibiting higher overall GD symptom-load and weekly time spent gaming compared to NPG. Furthermore, PG reported experiencing significantly higher frequency of gaming-related functional impairments compared to NPG, with the in particular affected areas for both PG and NPG being 'school and/or work', 'physical health', and 'family', with other key differences emerging in relation to other outcomes. Overall, the present findings show that not only GD symptom-load but also some functional impairment is higher in PG compared to NPG which highlights the need to develop and support prevention and intervention strategies for this at-risk population.

Problematic Gaming in Malaysian University Students: Translation and Psychometric Evaluation of the Malay Language Versions of Gaming Disorder Test and Gaming Disorder Scale for Young Adults

As research on gaming disorder (GD) is growing globally, the need for a valid and reliable instrument to assess GD has become crucial. Therefore, the present cross-sectional study translated and evaluated the psychometric properties of Gaming Disorder Test (GDT) and Gaming Disorder Scale for Young Adults (GADIS-YA) into Malay language versions. The sample comprised 624 university students (females = 75.6%; mean age = 22.27 years) recruited via an online survey from May to August 2022, using a convenience sampling method. Participants completed both GDT and GADIS-YA scales and other relevant measures including Bergen Social Media Addiction Scale (BSMAS), Internet Gaming Disorder Scale-Short Form (IGDS9-SF), and time spent on social media and gaming. Results showed that both instruments reported satisfactory internal consistency, and confirmatory factor analysis supported the one-factor structure for GDT and two-factor structure for GADIS-YA. Both scales were strongly correlated with each other and with the IGDS9-SF, BSMAS, and time spent on social media and gaming, supporting concurrent validity. Measurement invariance of both scales was confirmed across gender and gaming time. These findings suggest that the Malay versions of GDT and GADIS-YA are reliable and valid measures of problematic gaming among Malaysian university students.

Measurement Invariance of the Lemmens Internet Gaming Disorder Scale-9 Across Age, Gender, and Respondents

Although Internet gaming disorder (IGD) has gained increased attention in scientific, clinical, and community contexts, there is still a lack of consensus regarding the best assessment tools (i.e., self-report or other reports) for assessing its symptoms. The present study aimed to investigate the reliability, validity, and measurement invariance of both versions (youth and parent) of The Lemmens Internet Gaming Disorder Scale-9. To achieve this goal, we recruited between June and October 2019 from five Romanian highschools a total of 697 adolescents (11-19 years old) and one of their parents (N = 391). The internal consistency was good in both versions of the instrument (α = 0.772 for the youth version and α = 0.781 for the parent version). Construct validity assessed through confirmatory factor analysis showed support for the one factor structure of the scales, while multigroup confirmatory factor analysis endorsed the invariance across age, gender, and respondents (i.e., parent vs. youth report). The current research identifies both IGD scales to be reliable and valid, arguing for their utility for assessing IGD symptomatology among adolescents. Implications for theory, assessment, and future directions are discussed.

Depressive inclinations mediate the association between personality (neuroticism/conscientiousness) and TikTok Use Disorder tendencies

BACKGROUND

We introduce a novel measure for assessing TikTok overuse, called the TikTok Use Disorder-Questionnaire (TTUD-Q). As part of ongoing investigations into the suitability of the World Health Organization's (WHO) framework for diagnosing Gaming Disorder in the context of social media overuse, we developed this questionnaire by adapting the WHO framework, replacing the term "gaming" with "TikTok use".

METHODS

In order to address this question, we investigated the psychometric properties of the newly designed TTUD-Q and assessed its associations with the BFI-10 (assessing the Big Five of Personality) and the PHQ-8 (assessing depressive tendencies).

RESULTS

In this study, involving a final sample of 378 participants, we observed that higher levels of neuroticism were linked to greater tendencies toward TikTok Use Disorder (TTUD). Furthermore, we identified that this association was mediated by depressive tendencies. Similar trends emerged when investigating the relationship between lower levels of conscientiousness and higher TTUD tendencies, with depressive tendencies once again serving as a mediator.

DISCUSSION

Our research sets the foundation for future studies that should delve deeper into examining individual differences in TTUD using the WHO framework originally designed for Gaming Disorder.

The interplay between mental health and dosage for gaming disorder risk: a brief report

The relationship between gaming time and gaming disorder can be moderated by other variables. This study aimed to test the moderating role of mental health. Participants (N = 461) were recruited online. Gaming time was a statistically significant predictor of gaming disorder risk, with an explained variance of 3.3%. The goodness of fit of the model that took into account both moderators (anxiety and depression) improved to 13.9%. The interaction between gaming time and both moderators was significant. The results showed that depression and anxiety acted as moderators of the dosage effect, possibly by amplifying the gratification of playing games and thus contributing to the development of gaming disorder. It may be important in practise, as it seems to place the mental health at the right place, namely among risk factors that can contribute to gaming disorder in combination with a key trigger, which is gaming.

A Four-Item Questionnaire to Measure Problematic Social Media Use: The Social Media Disorder Test

While the use of video games and social media is an enjoyable recreational activity for most users, a minority develop problematic patterns of use. In the ICD-11, for the first time, there is a category of "disorders due to addictive behaviors" (including gaming disorder). The scientific literature also suggests a potential for the problematic use of social media. Economic screening tools for this are still needed. A very economical questionnaire to record gaming disorder is the ICD-11-based Gaming Disorder Test (GDT). The purpose of the present survey was to investigate the psychometric properties of an adapted questionnaire (Social Media Disorder Test, SMDT) to assess problematic social media use (PSMU). Therefore, 443 youths (mean age: 20.11 years) were examined with the SMDT and other measures regarding PSMU, self-control, and psychopathology. A confirmatory factor analysis (CFA) and reliability and correlation analyses were conducted. For the SMDT, we observed very good fit indices in the CFA, suggesting a one-factor structure; the reliability coefficient was 0.90, and we found the first indications for criterion validity. If the results can be confirmed, the SMDT, with its four questions, would be a very economical instrument to measure PSMU based on the ICD-11 criteria for behavioral addictions.

The Role of Self-Control Dimensions, Game Motivation, Game Genre, and Game Platforms in Gaming Disorder: Cross-Sectional and Longitudinal Findings

Introduction

Gaming disorder (GD) is the result of an interplay between gaming-related factors, individual factors, and environmental factors. Current research primarily highlights single types of factors. Consequently, the present study simultaneously analyzed the role of individual factors, such as self-control dimensions and motives for gaming, and gaming-related factors, such as game genres, and gaming platforms in GD among female and male gamers. Additionally, the study provides a comprehensive analysis of these factors in relation to GD both cross-sectionally (Study 1) and longitudinally (Study 2).

Methods

Study 1 comprised 620 active gamers (M=22.16 years; SD=2.99), and Study 2 comprised 405 active gamers (M=28.05 years; SD=4.51). The instruments used in the studies included the Gaming Disorder Test, the nine-item Internet Gaming Disorder Short-Form (IGDS9-SF), Motives for Online Gaming Questionnaire, Video Game Questionnaire, and Self-Knowledge New Sheet.

Results

The results showed that GD was associated with (i) self-control deficits associated with difficulties in implementation control and taking actions related to goals without unnecessary delay, (ii) retaining information about intentions and long-term plans, (iii) refraining from immediate, impulsive behavior, and (iv) inhibiting emotional reactions. GD was also associated primarily with escape, coping, and competition motives for gaming. However, the longitudinal study showed that social, fantasy, and skill-development motives were also related to GD development over time. The action game genres associated with GD but were not very important for GD over time. The cross-sectional study results indicated a negative relationship between GD and tablets and consoles used as gaming platforms. However, the longitudinal study showed that desktop computers and consoles use as gaming platforms were associated with the GD over time. Moreover, gaming-related factors explained only 9% of the variance in the GD model among female gamers and only 10% of the variance in the GD model among male gamers in cross-sectional study. In contrast, individual factors such as self-control dimensions and gaming motivation explained 32% of the variance in the GD model among both female and male gamers.

Conclusion

Individual factors, such as self-control dimensions and motives for gaming, were more important in explaining GD than gaming-related factors, such as game genres and gaming platforms. Moreover, self-control deficits and motivation related to escape, coping and competence can be important factors to consider in the prevention and treatment of GD.

Psychometric properties of the Persian Gaming Disorder Test and relationships with psychological distress and insomnia in adolescents

BACKGROUND

Gaming Disorder (GD) was recently included by the World Health Organization (WHO) as a psychiatric condition in the eleventh revision of the International Classification of Diseases (ICD-11) and is a concern worldwide, including in Iran. Thus, based on the ICD-11 criteria, a Persian version of the Gaming Disorder Test (GDT) was developed to facilitate assessment of GD.

METHODS

The present study used classical test theory and Rasch analysis to examine the psychometric properties of the Persian GDT. Iranian adolescents (n = 3837; 2171 [56.6%] males; mean [SD] age = 16.02 [1.4] years) completed the GDT and other instruments assessing disordered gaming, psychological distress, and insomnia.

RESULTS

Overall, the psychometric properties of the Persian GDT were satisfactory based on classical test theory (i.e., confirmatory factor analysis corroborated the unidimensional structure of GDT) and Rasch analysis (i.e., fit statistics suggested that all items were embedded in the concept of GD). Moreover, the Persian GDT was found to be sex-invariant, displaying no items with substantial differential item functioning across sexes. Additionally, it was found that GD mediated associations between time spent gaming and measures of psychological distress and insomnia.

CONCLUSION

The Persian GDT is a convenient and short instrument for assessing GD among Iranian adolescents. The mediating roles of GD in the associations between time spent gaming and psychological distress and between time spent gaming and insomnia suggest that targeting features of GD may reduce psychological distress and improve sleep for Iranian adolescents.

It's not just about how long you play. Indirect gaming involvement and genre preferences in predicting gaming disorder risk: evidence from preregistered studies

Introduction

The strength of the association between gaming involvement and gaming disorder is weak to moderate. Gamers cannot be directly involved in gaming all the time, but how much they are involved in activities indirectly related to gaming during gaming-free time may play an important role. Also, specific game genres may matter. The present investigation focuses on the role of indirect gaming involvement and genres in gaming disorder risk prediction.

Methods

Two pre-registered studies were conducted. Study 1 (N = 205) was conducted online, whereas Study 2 (N = 250) was conducted in a lab. In both cases, participants reported their direct and indirect involvement in gaming (DGI and IGI, respectively) and completed a screening tool that estimates the risk of gaming disorder (Gaming Disorder Test).

Results

Both IGI and DGI were weakly to moderately correlated with gaming disorder (GD) and moderately with each other. The correlations between DGI and GD were similar to those obtained in related studies; the correlation between IGI and GD has not been previously reported. Hierarchical regression that took IGI together with DGI into account showed an increase in the percentage of explained variance, but only in Study 1. Contrary to expectations, IGI did not interact with DGI. As is consistent with previous research, some game genres were found to be more closely related to GD than others: in both studies, this was an RPG; in Study 1, this was also an MMORPG; in Study 2, driving and shooting games also predicted GD risk.

Discussion

Overall, the results clearly indicate that not only gaming time plays a role in GD risk assessment: IGI can also predict it and in some cases may allow for more accurate predictions. Gaming genres once again proved to play a role, but these and similar results should be treated with caution due to the partial lack of repeatability.

Psychometric properties of the Problematic Use of Social Networks (PUS) scale in Arabic among adolescents

BACKGROUND

The Problematic Use of Social Networks (PUSN) scale assesses for the first time the comparative use of social networks along with addictive tendencies. However, it has only been validated in a Spanish sample. This study aimed to evaluate the psychometric properties of the Arabic version of the PUSN (PUSN-Ar) among Lebanese adolescents.

METHODS

A total of 379 adolescents aged between 15 to 18 years (M = 16.07 years; 64.9% females) participated in this cross-sectional study conducted between January and May 2022. The problematic use of social networks-SNS (PUSN) scale yields of two subscales: addiction-related consequences of SNS use (SNS-ARC) and negative social comparison (SNS-NSC). The Beirut Distress Scale, the Smartphone Addiction Scale and the Jong-Gierveld Loneliness Scale were used to assess psychological distress, smartphone addiction and loneliness respectively.

RESULTS

The PUS-Ar scale exhibited a two-dimensional structure (Comparative Fit Index [CFI] = .97; Root Mean Square Error of Approximation [RMSEA] = .08), consistent with the original scale. Both subscales, Negative Social Comparison (α = .96) and Addictive Consequences (α = .92), demonstrated excellent reliability. Additionally, measurement invariance was verified between males and females at the configural, metric and scalar levels. No significant difference was found between males and females in terms of SNS-NSC (20.75 ± 10.15 vs 21.09 ± 9.51; t(377) = -.32; p = .751) and SNS-ARC (19.08 ± 8.61 vs 19.76 ± 6.77; t(377) = -.79; p = .430). The SNS-ARC subscale was more correlated to smartphone addiction than the SNS-NSC (r = .73; p < .001 vs r = .54; p < .001) whereas both subscales were significantly associated with more stress and more loneliness.

CONCLUSION

The data collected in this study provided support for all the hypotheses formulated. Consequently, the PUS-Ar was deemed a suitable scale to measure problematic SNS among Lebanese adolescents. The PUS-Ar is currently available to researchers for use in evaluating PSNSU in Lebanon. However, it is important to note that further research is needed to explore its applicability and generalizability across different populations and contexts.

Circadian typologies and insomnia in individuals with internet gaming disorder comorbid with attention deficit/hyperactivity disorder

The alteration in circadian typology and insomnia were prevalent among both Individuals with IGD and those with attention deficit hyperactivity disorder (ADHD), the most comorbid psychiatric disorder of IGD. This study aimed to evaluate the relationships between circadian typologies, insomnia, and internet gaming disorder (IGD) and how ADHD affects this relationship. We recruited three groups of 69 young adults: an IGD group, a control group comprising age- and sex-matched nongamers, and a group of gamers without IGD through diagnostic interviews. The participants with IGD exhibited lower composite scale of morningness (CSM) scores and thus a higher eveningness preference In addition, the score of Pittsburgh insomnia rating scale-20-item version (PIRS_20) was significantly higher among those with IGD. The participants with IGD and ADHD exhibited lower CSM scores but higher PRIS_20 scores than the participants with IGD but without ADHD. The present findings indicate that participants with IGD exhibited a tendency of eveningness preference and experienced more severe insomnia. ADHD exacerbated the eveningness preference and insomnia of individuals with IGD. Close attention should be paid to sleep problems in individuals with IGD, particularly to those with ADHD.

Psychometric properties and development of the Chinese versions of Gaming Disorder Test (GDT) and Gaming Disorder Scale for Adolescents (GADIS-A)

Currently, six instruments have been developed using the 11th revision of the International Classification of Diseases (ICD-11) criteria for Gaming Disorder (GD). Two of these are the Gaming Disorder Test (GDT) and Gaming Disorder Scale for Adolescents (GADIS-A). The present study validated both the GDT and GADIS-A among a large sample of Chinese emerging adults. Via an online survey, 3381 participants (56.6% females; mean age = 19.56 years) completed the Chinese versions of the GDT, GADIS-A, Internet Gaming Disorder-Short Form (IGDS9-SF), and Bergen Social Media Addiction Scale (BSMAS). Confirmatory factor analysis was used to examine the factor structure of the Chinese GDT and GADIS-A. Pearson correlations were computed to examine the convergent validity (with IGDS9-SF) and divergent validity (with BSMAS) of the Chinese GDT and Chinese GADIS-A. The GDT had a unidimensional structure, which was invariant across sex and disordered gaming severity subgroups. The GADIS-A had a two-factor structure, which was also invariant across gender and gaming severity subgroups. Both the GDT and GADIS-A had significant associations with both IGDS9-SF and with BSMAS. Both the Chinese GDT and GADIS-A are valid instruments to assess GD among emerging adults in mainland China, enabling healthcare providers to adopt these tools in their efforts to prevent and examine GD severity among Chinese youth.

Translation and Validation of the Gaming Disorder Test and Gaming Disorder Scale for Adolescents into Chinese for Taiwanese Young Adults

PURPOSE

To translate and cross-culturally adapt the Gaming Disorder Test (GDT) and Gaming Disorder Scale for Adolescents (GADIS-A) for use in Taiwan and to validate their internal consistency, construct validity, measurement invariance, and convergent validity in Taiwanese young adults.

METHODS

The GDT and GADIS-A were translated into traditional (unsimplified) Chinese characters and culturally adapted according to standard guidelines. A sample of 608 Taiwanese university students were recruited online. All participants completed the GDT, GADIS-A, Internet Gaming Disorder Scale - Short Form (IGDS9-SF), and Depression Anxiety Stress Scale-21 (DASS-21). Internal consistency was assessed using Cronbach's α and McDonald's ω. Factor structure was examined using Confirmatory Factor Analysis (CFA). Measurement invariance in gender was assessed by three nested models in CFA. Convergent validity was determined by calculating Pearson's r among the GDT, GADIS-A, IGDS9-SF, and DASS-21.

RESULTS

The GDT and GADIS-A showed adequate internal consistency (both α and ω = 0.90). The CFA results supported a one-factor structure for the GDT and a two-factor structure for the GADIS-A. Measurement invariance across gender was supported for both the GDT and GADIS-A. The convergent validity of the GDT and GADIS-A were acceptable.

CONCLUSIONS

The Chinese versions of the GDT and GADIS-A are valid and reliable tools that can be used to assess gaming disorder in Taiwanese young adults. Measurement invariance across genders was supported for both tools. The convergent validity of the GDT and GADIS-A were also satisfactory.

Collection of smartphone and internet addiction

The enigma of smartphone and internet addiction has plagued academics for the last decade, now scholars believe this behavior might have a substantial effect on human health and social issues. However, there are literature gaps. Thus, BMC Psychiatry works with us to launch the special collection "Smartphone and Internet Addiction".

"I have no control over how much time I play" the metacognitions about online gaming scale: Evidence from a cross-cultural validation among Israeli adolescents

In the current study we evaluated the psychometric properties of the Metacognitions about Online Gaming Scale (MOGS), including its factor structure, reliability, and predictive validity among Israeli adolescents in a six-month prospective study. We also examined the usefulness of the MOGS as a mediator of the effect of attachment patterns on Internet Gaming Disorder (IGD), the preference for online social interactions, and the motives for online gaming. The study population included 1,056 Israeli adolescents (610 males and 446 females, M = 15.77, standard deviation (SD) = 1.43) with an age range of 13-18 years. The participants completed the translated Hebrew version of the MOGS and measures on attachment style, IGD, preference for online social interactions, emotion regulation, and motives for online gaming. The analyses indicated that the factorial structure of the Hebrew MOGS comprised the expected two factors at T1 and T2 (a six-month follow-up). We also found that positive and negative metacognitions significantly mediated the effect of attachment styles on IGD, the preference for online social interactions, and the motives for online gaming. The findings provide evidence that the Hebrew MOGS among Israeli adolescents appears psychometrically appropriate for use by researchers and practitioners dealing with the prevention and treatment of IGD.

Gender differences and left-behind experiences in the relationship between gaming disorder, rumination and sleep quality among a sample of Chinese university students during the late stage of the COVID-19 pandemic

Background and aims

Studies have shown that gaming disorder (GD) is associated with rumination and poor sleep quality. However, the reciprocal relationship between GD, rumination and sleep quality is unclear. Moreover, the differences between gender and between left-behind experiences in the aforementioned relationship remain unknown. Therefore, the present study examined gender differences and left-behind experiences in the relationship between GD, rumination, and sleep quality among a sample of Chinese university students during the late stage of COVID-19 pandemic using a network analysis approach.

Methods

A cross-sectional online survey of 1,872 Chinese university students was conducted comprising demographic information (age, gender, and left-behind experience), gaming experience, gaming frequency, Gaming Disorder Test (GDT), Short Version of Rumination Response Scale (RRS), and Pittsburgh Sleep Quality Index (PSQI).

Results

Among Chinese university students, the prevalence of (i) GD was 3.5% and (ii) sleep disturbance was 14%. GD had positive and weak connection with rumination and sleep quality in the domain-level relational network. The network structures and global strengths both showed no significant differences between gender and between left-behind experiences. The nodes gd3 ("continuation or escalation of gaming") and gd4 ("gaming problems") had the strongest edge in the network.

Conclusion

The results suggest reciprocal relationships between GD, rumination, and sleep quality. Gender and left-behind experiences did not influence the reciprocal relationship between GD, rumination, and sleep quality during the late stage of COVID-19 pandemic. Using network analysis, the findings provide novel insights that rumination and sleep quality may have interacted with GD among Chinese students during the late stage of COVID-19 pandemic. Reducing or eliminating negative rumination may decrease GD and improve sleep quality. Moreover, good sleep quality contributes to positive rumination which may decrease the risk of GD among Chinese university students.

Motives to play videogames across seven countries: Measurement invariance of the Videogaming Motives Questionnaire

INTRODUCTION

Gaming motives appear to be an important predictor of time spent gaming and disordered gaming. The Videogaming Motives Questionnaire (VMQ) has shown adequate psychometric properties to assess gaming motives among Spanish college students. However, the utility of this measure has not yet been explored in other cultures. This research aimed to examine the structure and measurement invariance of the VMQ across seven countries and gender groups, and to provide criterion-related validity evidence for VMQ scores.

METHOD

College students who reported having played videogames in the last year (n = 5192; 59.07 % women) from the US, Canada, South Africa, Spain, Argentina, England, and Uruguay completed an online survey to measure time spent gaming, disordered gaming, and the VMQ.

RESULTS

Findings support a 24-item 8-intercorrelated factor model structure for the VMQ in the total sample. Our results also support configural, metric, and scalar invariance of the VMQ across gender groups and countries. Students from North America (US and Canada) scored higher on most gaming motives (except recreation and cognitive development) than students from the other countries. The correlations between VMQ and non-VMQ variables were similar across gender and countries, except in England where VMQ correlations with time spent gaming were stronger.

DISCUSSION

These results suggest that the VMQ is a useful measure for assessing gaming motives across young adults from different countries.

Understanding adolescent esports bettors: Are they a homogeneous group?

With the rapid rise of competitive video gaming (esports), increased attention has been placed on understanding the profiles of youth who wager on esports. With adolescents being at increased risk of gambling problems and endorsing high rates of past year engagement in video games, there is a need for research investigating psychological and social correlates of adolescent esports bettors and to identify whether youth who engage in esports betting are a homogenous group. Survey responses were collected from 5,997 high-school students (48.4 % male, Mage = 14.7 years [SD = 1.6], age range 12-17) from Wood County, Ohio, United States. A latent class analysis was conducted to identify subgroups of esports bettors based on self-reported measures of gambling frequency, risk for problem gambling, gaming frequency, disordered gaming, preference for virtual life and risky loot box use. Results indicated that 5.5 % of the sample reported esports betting over the past year. Four classes of esports bettors were identified which were indicative of a group of low-risk esports bettors, a group of esports bettors at risk of gaming problems, a group of esports bettors at risk of gambling problems, and a group of esports bettors at high risk of both gambling and gaming problems. Although no significant differences based on sex and age were noted between the classes, differences were noted in experienced childhood adversity, mental health symptoms and problem behavior severity. Results are discussed in line with previous findings relevant to adolescent and adult esports betting.

Relationships Between Gaming Disorder, Risk Factors, and Protective Factors Among a Sample of Chinese University Students Utilizing a Network Perspective

Research has demonstrated that some risk and protective factors of gaming disorder (GD) have been identified. However, the interaction of GD with risk and protective factors has rarely been examined from a network analysis perspective. Therefore, the present study examined the relationships between GD, risk factors (i.e., social anxiety and fear of missing out), and protective factors (i.e., resilience, authenticity, and family closeness) utilizing a network analysis approach among a sample of Chinese university students. A cross-sectional study with 1364 participants was performed using the Gaming Disorder Test, the short version of Social Interaction Anxiety Scale (SIAS), the Chinese Trait-State Fear of Missing Out Scale (T-SFoMOSC), the Brief Resilience Scale (BRS), the Authenticity Scale, and a single item assessing family closeness. Social anxiety, FoMO, and two factors of authenticity (i.e., self-alienation and accepting external influence) had positive relationship with GD, while resilience, authentic living, and family closeness had negative relationship with GD. Social anxiety was identified as the core node in the domain-level network. The item "continuation or escalation of gaming" (gd3) and the item "gaming problems" (gd4) constituted the highest edge weight in the facet-level network. The network comparison demonstrated there were no significant differences in relation to network structures and global strengths between gender. The findings suggest bivariate relationships among GD, risk factors (i.e., social anxiety and fear of missing out), and protective factors (i.e., resilience, authenticity, and family closeness). Interventions for GD must be considered through preventing risk factors and increasing protective factors including improving the gaming motivation and maladaptive cognition to decrease negative emotion (e.g., social anxiety and FoMO), enhancing resilience, authentic living and parent-child relationship, as well as decreasing self-alienation and accepting external influence.

Psychometric validity and the appropriateness of tolerance as a criterion for internet gaming disorder: A systematic review

Tolerance is a controversial but still an omnipresent criterion in measuring problematic gaming and Internet Gaming Disorder (IGD). Despite criticisms, a systematic review of its suitability has not been conducted until now. The aim of this study was to assess the evidence of psychometric validity and the appropriateness of tolerance as a criterion for IGD. A total of 61 articles were included in the review, 47 quantitative, 7 qualitative studies,plus 7 studies that introduce potential item wordings for operationalizing tolerance. Results showed that the tolerance item tends to have acceptable to high factor loadings on the single IGD factor. While tolerance sometimes did not adequately differentiate the engaged gamers from those with a probable disorder, it was endorsed at medium to high levels of IGD severity and had a good performance in the interviews. It, however, showed weak relations with distress and well-being. In qualitative studies, tolerance as currently defined by DSM-5 and measured by questionnaires (i.e., increasing amounts of time spent on gaming) was almost unequivocally rejected by gamers. The solid performance of tolerance in psychometric studies was probably due to deficiencies of the IGD construct, which also contains other disputed criteria. Tolerance lacks relevance in measuring IGD and care should be taken when using and interpreting IGD measures with this criterion.

Parents Rate Problematic Video Streaming in Adolescents: Conceptualization and External Assessment of a New Clinical Phenomenon Based on the ICD-11 Criteria of Gaming Disorder

In recent years, video streaming (VS) increased substantially. Adolescents are at significant risk of presenting problematic VS patterns associated with a spectrum of mental-health difficulties. Because VS platforms rely on similar mechanisms as digital games, the ICD-11 criteria for Gaming Disorder (GD) have been successfully implemented to measure Streaming Disorder (StrD) in adolescents. For proper diagnoses, external rating scales are urgently required in addition to self-reports. The Streaming Disorder Scale for Parents (STREDIS-P) was created and validated in a representative sample of n = 891 adolescent-parent dyads. Mental health problems were assessed with standardized instruments. Confirmatory factor analysis was conducted to examine the underlying factor structure. Cutoff scores were determined using ROC analysis. Accordance between parental and adolescents' self-ratings was calculated. Consistent with the results of previous validation studies for screening instruments assessing similar phenomena based on ICD-11-GD criteria, two factors, cognitive-behavioral symptoms and negative consequences, were confirmed. STREDIS-P demonstrated good to excellent internal consistency, criterion validity, and discriminatory power. Accordance with adolescents' self-ratings was moderate. STREDIS-P is the first screening tool for assessing StrD in adolescents by parental ratings. It is highly relevant for conceptualizing a new phenomenon in clinical routine and academic research.

Psychometric properties of three online-related addictive behavior instruments among Bangladeshi school-going adolescents

BACKGROUND

Due to the ease of access to the internet in modern society users have become more prone to experiencing addictive behaviors online. The present study aimed to develop and investigate the psychometric properties of the Bangla Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), Gaming Disorder Test (GDT), and Bergen Social Media Addiction Scale (BSMAS) due to a lack of existing sound psychometric tools in Bangladesh.

METHODS

A cross-sectional paper-and-pencil survey was carried out among 428 school-aged adolescents who were active gamers (90.89% males; Meanage: 16.13±1.85 years; age range: 10-19 years). Participants were recruited using convenience sampling across four selected schools in Dhaka City, Bangladesh. Data collected included sociodemographic information, frequency of internet use and gaming behaviors, psychological states (i.e., Patient Health Questionnaire [PHQ-9], Generalized Anxiety Disorder [GAD-7]), disordered gaming and social media use (i.e., IGDS9-SF, GDT, and BSMAS). Psychometric testing was conducted to examine the validity and reliability levels of the Bangla IGDS9-SF, GDT, and BSMAS.

RESULTS

The newly adapted Bangla IGDS9-SF, GDT, and BSMAS exhibited adequate levels of internal consistency. All total scores were significantly correlated with depression, anxiety, frequencies of internet use/online activities and gaming, supporting criterion and convergent validity. CFA indicated excellent construct validity as all instruments had a good fit to the data.

CONCLUSIONS

The findings suggest that the Bangla IGDS9-SF, GDT, and BSMAS are sound psychometric instruments due to their satisfactory psychometric properties including internal consistency, criterion validity, convergent validity, and construct validity.

Associations between levels of Internet Gaming Disorder symptoms and striatal morphology-replication and associations with social anxiety

Background

Brain structural alterations of the striatum have been frequently observed in internet gaming disorder (IGD); however, the replicability of the results and the associations with social-affective dysregulations such as social anxiety remain to be determined.

Methods

The present study combined a dimensional neuroimaging approach with both voxel-wise and data-driven multivariate approaches to (i) replicate our previous results on a negative association between IGD symptom load (assessed by the Internet Gaming Disorder Scale-Short Form) and striatal volume, (ii) extend these findings to female individuals, and (iii) employ multivariate and mediation models to determine common brain structural representations of IGD and social anxiety (assessed by the Liebowitz Social Anxiety Scale).

Results

In line with the original study, the voxel-wise analyses revealed a negative association between IGD and volumes of the bilateral caudate. Going beyond the earlier study investigating only male participants, the present study demonstrates that the association in the right caudate was comparable in both the male and the female subsamples. Further examination using the multivariate approach revealed regionally different associations between IGD and social anxiety with striatal density representations in the dorsal striatum (caudate) and ventral striatum (nucleus accumbens). Higher levels of IGD were associated with higher social anxiety and the association was critically mediated by the multivariate neurostructural density variations of the striatum.

Conclusions

Altered striatal volumes may represent a replicable and generalizable marker of IGD symptoms. However, exploratory multivariate analyses revealed more complex and regional specific associations between striatal density and IGD as well as social anxiety symptoms. Variations in both tendencies may share common structural brain representations, which mediate the association between increased IGD and social anxiety.

Relationship between Medical Students' Perceived Stress and Gaming Behavior at King Saud University

Gaming addiction has gradually developed among medical students and has been a contentious topic for nearly a decade. This study is aimed at estimating the prevalence of gaming addiction among medical students at King Saud University and examining the relationship between perceived stress levels and gaming addiction. We conducted a cross-sectional study among 370 students from 2019 to 2020 using a self-reporting questionnaire consisting of two validated test scales: the Gaming Disorder Test and the Perceived Stress Scale. The questionnaire was sent to all students through an email. Descriptive analyses and t-test statistical tests were used in this study. The prevalence rate of gaming addiction was found to be 4.6%, while the prevalence of perceived stress was confirmed at 95.9%. Students with excellent GPAs and high family income were associated (p < 0.001). Younger groups, females, and students with high family incomes showed higher levels of perceived stress than others. According to Pearson's correlation, gaming addiction was not significantly correlated with stress among medical students (p > 0.05). According to chi-square test also, no significant association was found between gaming disorder and perceived stress (χ ² = 4.412; p = 0.353). In conclusion, gaming addiction among medical students has scored low prevalence, indicating gaming is not a factor contributing to stress among this group. The high level of perceived stress among medical students should draw attention to the provision of regular psychological care.

Opposing associations of Internet Use Disorder symptom domains with structural and functional organization of the striatum: A dimensional neuroimaging approach

BACKGROUND

Accumulating evidence suggests brain structural and functional alterations in Internet Use Disorder (IUD). However, conclusions are strongly limited due to the retrospective case-control design of the studies, small samples, and the focus on general rather than symptom-specific approaches.

METHODS

We here employed a dimensional multi-methodical MRI-neuroimaging design in a final sample of n = 203 subjects to examine associations between levels of IUD and its symptom-dimensions (loss of control/time management, craving/social problems) with brain structure, resting state and task-based (pain empathy, affective go/no-go) brain function.

RESULTS

Although the present sample covered the entire range of IUD, including normal, problematic as well as pathological levels, general IUD symptom load was not associated with brain structural or functional alterations. However, the symptom-dimensions exhibited opposing associations with the intrinsic and structural organization of the brain, such that loss of control/time management exhibited negative associations with intrinsic striatal networks and hippocampal volume, while craving/social problems exhibited a positive association with intrinsic striatal networks and caudate volume.

CONCLUSIONS

Our findings provided the first evidence for IUD symptom-domain specific associations with progressive alterations in the intrinsic structural and functional organization of the brain, particularly of striatal systems involved in reward, habitual and cognitive control processes.
