Psychometric properties of the Internet Gaming Disorder Test (IGDT-10) and problematic gaming behavior among Finnish vocational school students

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

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

Colliding harms of gambling and gaming: A four-wave longitudinal population study of at-risk gambling and gaming in Finland

Aims: Both gambling and digital gaming are growing in popularity and there is ongoing discussion about their convergence. This population-based longitudinal survey study investigated how gambling and digital gaming types contribute to at-risk gambling and gaming. Methods: The study was based on a representative sample of 18-75-year-olds from mainland Finland. Survey data were collected at 6-month intervals in 2021-2022, starting in April 2021. Of original T1 respondents, 58.95% took part in all four time points. In total, 3,608 observations from 902 individuals were analysed. Outcome measures were at-risk gambling and gaming based on the Problem Gambling Severity Index and the Internet Gaming Disorder Test. Various types of gambling and gaming were investigated. Results: Population-averaged models showed that different forms of gambling were associated with a higher risk of at-risk gaming. Online casino games were associated with the highest likelihood of at-risk gambling and gaming. Prevalence of digital gaming problems was low. Hybrid models were used to investigate the longitudinal within-person and between-person effects of gambling and gaming activities. Online casino games and offline slot machines increased at-risk gambling. Microtransactions within digital games increased at-risk gambling and gaming over time, but the amount of money spent on digital gaming was small compared to gambling. Conclusions: Our results underline the risks of EGMs and online gambling for the participants. Although gambling and gaming are converging, harm is mostly based on gambling.

Comparing psychopathological symptoms, life satisfaction, and personality traits between the WHO and APA frameworks of gaming disorder symptoms: A psychometric investigation

INTRODUCTION

The inclusion of Internet Gaming Disorder (IGD) in the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) by the American Psychiatric Association and Gaming Disorder in the 11th revision of the International Classification of Diseases (ICD-11) by the World Health Organization requires consistent psychological measures for reliable estimates. The current study aimed to investigate the psychometric properties of the Gaming Disorder Test (GDT), the Ten-Item Internet Gaming Disorder Test (IGDT-10), and the Five-Item Gaming Disorder Test (GDT-5) and to compare the WHO and the APA frameworks of gaming disorder symptoms in terms of psychopathological symptoms, life satisfaction, and personality traits.

METHODS

A sample of 723 Swedish gamers was recruited (29.8% women, 68.3% men, 1.9% other, Mage = 29.50 years, SD = 8.91).

RESULTS

The results indicated notable differences regarding the estimated possible risk groups between the two frameworks. However, the association between gaming disorder symptoms and personality traits, life satisfaction, and psychopathological symptoms appeared consistent across the two frameworks. The results showed excellent psychometric properties in support of the one-factor model of the GDT, IGDT-10, and GDT-5, including good reliability estimates (McDonald's omega) and evidence of construct validity. Additionally, the results demonstrated full gender and age measurement invariance of the GDT, IGDT-10, and GDT-5, indicating that gaming disorder symptoms are measured equally across the subgroups.

CONCLUSION

These findings demonstrate that the IGDT-10, GDT-5, and GDT are appropriate measures for assessing gaming disorder symptoms and facilitating future research in Sweden.

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.

The association of problematic gaming characteristics with dietary habits among Finnish vocational school students

Digital gaming is a popular pastime among young people, but its links to dietary habits have been little studied. The purpose of the study was to describe dietary habits and to examine their associations to problematic gaming behavior with regard to the degree of daily digital gaming time and the overall levels of disordered-like gaming behavior among students in vocational education in the Oulu region of Finland. This cross-sectional study consisted of a total of 773 first-year vocational school students who had played digital games regularly. Data was collected by using an online survey measuring sociodemographic information, dietary habits, amount of digital gaming time, and symptoms of problematic gaming behavior. Most prevalent weekly consumed food types were chicken (90.1%), chips (87.7%), and sausages/cold cuts (85.4%). Around one-fourth of students skipped breakfast on weekdays and at weekends. A higher amount of digital gaming time was associated with skipping breakfast on weekdays. More elevated levels of disordered gaming behavior were particularly associated with the use of a group of food types encompassing carbohydrate-dense and fast food. Current research provides indications that digital gaming may have an impact on youths' dietary habits, while at the same time, however, emphasizing that the issue can be affected by several interrelated and complex factors.

Basic psychological needs in gambling and gaming problems

•

Need frustration was related to the severity of gambling and gaming problems.

•

Need satisfaction was not related to the absence of gambling or gaming problems.

•

Higher mental health problems were related to the risk of any gaming problems.

Background and Aims

Studies on self-determination theory (SDT) have placed satisfaction of basic psychological needs (autonomy, relatedness, and competence) at the core of well-being, whereas frustration of these needs results in multiple potentially unhealthy mental and behavioral patterns. This study analyzed how need satisfaction and frustration relate to the severity of gambling and gaming problems.

Methods

A survey study with 18–75-year-old Finnish participants (N = 1530; 50.33% male) was conducted in April 2021. Basic psychological needs were measured with the Basic Psychological Need Satisfaction and Frustration Scale, mental health issues with the five-item Mental Health Inventory, gambling problems with the Problem Gambling Severity Index, and gaming problems with the Internet Gaming Disorder Test. Zero-inflated negative binomial analyses were conducted to examine how satisfaction and frustration of basic psychological needs, together with mental health issues, are associated with gaming and gambling problems.

Results

Mental health issues were associated with gambling and gaming problems, but this association became nonsignificant when basic psychological needs were added to the model. However, better mental health still was associated with the absence of gaming problems. While need satisfaction had no association with the absence of gaming or gambling problems, need frustration was associated with increases in the severity of both gaming and gambling problems.

Discussion

Frustration of basic psychological needs for autonomy, relatedness, and competence is associated with both gambling and gaming problems and should be considered when developing treatment and support for those who experience such problems.

Validation of the Ten-Item Internet Gaming Disorder Test (IGDT-10) based on the clinical diagnosis of IGD in Japan

BACKGROUND AND AIMS

Although the Ten-Item Internet Gaming Disorder Test (IGDT-10) has been translated into Japanese and widely used, the Japanese version has not previously been validated. We used the clinical diagnosis of IGD as a gold standard for validating the test.

METHODS

The Japanese version was validated using 244 gamers drawn from the general young population in Japan. Expert interviews using the Japanese version of the Structured Clinical Interview for Internet Gaming Disorder evaluated diagnoses of Internet gaming disorder (IGD). This resulted in a diagnosis of IGD for eight individuals, categorized as the gold standard group. The screening performance of the two Japanese versions with different scoring conditions was examined: the scoring method proposed by the original study (original version) and a less stringent scoring method where responses of either "often" or "sometimes" were regarded as affirmative (modified version).

RESULTS

The results of the sensitivity and specificity analyses, the Cronbach's alpha and the receiver operating characteristics analysis revealed a higher screening performance for the modified versus the original version. The optimum cutoff for the modified version was 5 or more - the sensitivity, specificity, and Youden's index were 87.5, 85.2, and 72.7%, respectively. The rate of probable IGD using the original and modified versions were 1.8% and 11.3%, respectively.

DISCUSSION AND CONCLUSION

A less stringent scoring method for the Japanese version of IGDT-10 showed a higher screening performance than the original scoring method. Future studies comprising different ethnic groups and gaming cultures should further examine the suggested scoring method.

Escapism and Excessive Online Behaviors: A Three-Wave Longitudinal Study in Finland during the COVID-19 Pandemic

Excessive online behaviors refer to harmful or disproportionate use of digital network applications. Such behaviors are likely to be associated with escapist motives. Our aim was to analyze whether escapism predicts excessive gambling, excessive gaming, and excessive internet use over time. A longitudinal sample of Finnish residents aged 18-75 years (n = 1022, 51.27% male) was surveyed at three time points during the COVID-19 pandemic in 6-month intervals: April 2021 (Time 1), October-November 2021 (Time 2), and April-May 2022 (Time 3). Of the original Time 1 respondents, 66.80% took part in the surveys at both Time 2 and Time 3. All surveys included measures for excessive gambling (Problem Gambling Severity Index), excessive gaming (Internet Gaming Disorder Test), and excessive internet use (Compulsive Internet Use Scale). Three escapism-specific questions were used to construct a dedicated escapism variable. Socio-demographic variables, alcohol consumption, and psychological distress were used as controls. The study was conducted with multilevel regression analyses using hybrid models. Our research showed that escapism had strong within-person effects on excessive gambling, B = 0.18, p = 0.003; excessive gaming, B = 0.50, p < 0.001; and excessive internet use, B = 0.77, p < 0.001 over time. The between-person effect of escapism was demonstrated on excessive gaming B = 0.91, p < 0.001, and excessive internet use B = 0.61, p = 0.036. Adverse societal events and uncertain times can manifest in excessive online behaviors motivated by escapism, highlighting a need to focus prevention efforts on healthy coping methods.

Gambling and gaming during COVID-19: The role of mental health and social motives in gambling and gaming problems

BACKGROUND

The uncertain and stressful global situation caused by the COVID-19 pandemic has the potential to cause anxiety and impact people's mental health. Simultaneously, social distancing policies have isolated people from their normal social interactions. These societal changes have inevitably influenced gambling and gaming practices, and many people may have turned to betting or gaming as a means of social exchange. This study examined the influence of COVID-19 anxiety on increased mental health problems and their relationship to gambling and gaming problems. The mediating role of social motives for gambling and gaming was also investigated.

MATERIAL AND METHODS

Finnish adults (N = 1530; Mage = 46.67; 50.33% male) were recruited from a volunteer participant panel to participate in a survey study. COVID-19 anxiety was assessed using a scale adapted from the Spielberger State-Trait Anxiety Inventory. Mental health problems were evaluated with the five-item Mental Health Inventory. Gambling problems were measured using the Problem Gambling Severity Index, and gaming problems were measured with the Internet Gaming Disorder Test. Social motives for gaming were evaluated using a single-item measure. Analyses used generalised structural equation modelling.

RESULTS

COVID-19 anxiety predicted increased mental health problems, which were associated with heightened gambling and gaming problems. Social motives for gambling and gaming were a significant mediator, suggesting that gambling and gaming problems are emphasized markedly among those who are socially motivated by and involved in such games.

CONCLUSIONS

Mental health problems experienced during the pandemic and the social properties of games might accentuate gambling and gaming problems.

Think-aloud analysis of commonly used screening instruments for Internet use disorders: The CIUS, the IGDT-10, and the BSMAS

Background

Despite the constant publication of new screening instruments for Internet use disorders (IUD), little is known about their content validity. This study aimed to identify potential mismatches between the items' intention and young adults' interpretation of these items when answering three screening instruments that are commonly used in research and clinical settings: The Compulsive Internet Use Scale (CIUS), the 10 Item-Internet Gaming Disorder Test (IGDT-10), and the Bergen Social Media Addiction Scale (BSMAS).

Methods

In total, 30 vocational students (50% female, age = 21.3; SD = 2.1) took part in individual think-aloud interviews. All participants were asked to report their thoughts while completing the CIUS. In addition, participants who reported online games (OG) as their main Internet activity (n = 11) answered the IGDT-10. Participants who reported social networks (SN) as their main Internet activity (n = 18) answered the BSMAS. One participant used OG and SN equally and completed both screening instruments. All interviews were audio-recorded, transcribed, and content-analysed.

Results

Overall, four potential sources for errors were identified: (1) High scorings were often not congruent with the underlying diagnostic criteria. In particular, such discrepancies were found in items aimed to assess dysfunctional emotional regulation strategies and cognitive involvement. (2) Some participants were uncertain which time frame or Internet activity should be considered in their answers. (3) Long and complex items led to the building of mean values or the choice of the middle answer category. (4) Some wordings were perceived to be outdated and difficult to understand.

Discussion

These findings might help to provide recommendations on how to improve screening instruments for IUD. Most important, items should more clearly distinguish between Internet use as a "normal" leisure activity and Internet use that leads to functional impairments in daily life.

Exploring Internet gaming disorder: an updated perspective of empirical evidence (from 2016 to 2021)

BACKGROUND AND AIMS

Since the acceptance of Internet gaming disorder (IGD) as a "disorder due to addictive behaviors", research has proliferated exponentially. The present review focuses on the conceptualization of IGD, its diagnosis and assessment, associated factors and existing prevention and treatment plans to address it.

RESULTS AND CONCLUSIONS

The discrepancies between the diagnostic criteria for IGD proposed by the two central diagnostic entities, as well as the questioning of their clinical validity, have generated multiple proposals for the diagnosis and psychometric evaluation of IGD. Likewise, there have been numerous suggestions to prevent this pathology, with the involvement of governments, the gaming industry and health institutions. Finally, multiple treatment plans have been proposed, both pharmacological and psychological, although only the efficacy of cognitive behavioral therapy has been tested. It is essential, therefore, to delve deeper into this disorder by addressing the central limitations of the current literature.

Psychometric properties of the Indonesian Ten-item Internet Gaming Disorder Test and a latent class analysis of gamer population among youths

Internet gaming disorder (IGD) is a rising health concern. Indonesia has yet to have any validated instrument specifically designed to screen for this disorder. This study aims to validate the Indonesian version of the Ten-item Internet Gaming Disorder Test (IGDT-10) and conduct a latent class analysis of gamers among the youth. An online survey was conducted between October and December 2020 at two universities in Depok and Jakarta, Indonesia. In total, 1233 respondents (62.6% female and 20.3±1.90 years old) gave valid responses and played video games. Confirmatory factor analysis (CFA) confirmed the unidimensional structure of the scale. Cronbach’s alpha was 0.72 and composite reliability was 0.92. The latent class analysis yielded three distinct classes of gamers. The continuation and negative consequences were highly distinctive for the group at high risk of IGD (class 3). Deception had the lowest endorsement rate (41.7%); while, the continuation domain had the highest endorsement, 91.2%. The IGD prevalence estimate was 1.90% among the respondents. Approximately 70.2% of the gamers did not show IGD symptoms. The adapted Indonesian IGDT-10 was demonstrated as valid and reliable among Indonesian youths. Consistent with previous studies, the deception domain had a low endorsement rate. The detected IGD rates were comparable to the global range. The majority of the current sample disclosed no symptoms; however, a considerable proportion would benefit from early preventive measures.

The effects of an early intervention on adults' gaming-related problems - a pilot study

Gaming Disorder (GD) has been recognized as an official psychiatric condition characterized by individuals' impaired control over gaming, continuous gaming despite the occurrence of negative side-effects, and gaming taking increasing priority over other important areas of life, thus leading to significant impairments in their everyday lives. To date few prevention and treatment programs have been developed. The present pilot study aimed to investigate the effects of an early psycho-educational intervention for young adults with excessive gaming behaviors. A one-group pre- and post-test design without a control group was used. A total of 22 young adults (20 males and 2 females) aged between 18 and 28 (M = 23.05, SD = 3.02) years old, engaged with the intervention. The severity of gaming-related problems, average gaming time per day, quality of life, and mental well-being were assessed at pretest and post-test stages. Participants demonstrated a slight reduction in gaming time (d = 0.13, p = .545 for weekdays, and d = 0.08, p = .714 for weekend days) and in the severity of problematic gaming (d = 0.17, p = .411) over the three-month intervention period. Changes in neither gaming-related measures nor self-assessed quality of life (p > .01) and mental well-being (d = 0.23, p = .288) reached statistical significance, however. Regardless of limitations on sample size, this study shows encouraging signs that this brief 10-session and three-month educational intervention can achieve positive effects on gaming behavior. A larger scale investigation is needed to develop the intervention further.

Risk Factors for Excessive Social Media Use Differ from Those of Gambling and Gaming in Finnish Youth

Purpose: Adolescents’ excessive social media use has characteristics similar to other addictive behaviours. This study aims to explore whether the same risk factors are associated with excessive social media use as with excessive gaming and gambling among Finnish adolescents. Methods: Multinomial logistic regression analyses were carried out using the European School Survey Project on Alcohol and Other Drugs data, collected from Finnish adolescents aged 15–16 in 2019 (n = 4595). Results: Excessive use of social media was more common among girls (reported by 46% of respondents) than boys of the same age (28%), whereas boys reported both excessive gaming (23%) and gambling (6%) more often than girls (4% and 1%, respectively). All differences between genders were statistically significant (p < 0.0001). Daily smoking was associated with a high risk of excessive gambling (AOR = 3.23) and low risk of excessive gaming (AOR = 0.27) but had no significant effect on excessive social media use. Cannabis use in the past 12 months was positively associated only with excessive gambling (AOR = 2.39), while past 12 months alcohol consumption increased the risk for excessive social media use (AOR = 1.25). Conclusions: Adolescent girls are at greater risk of excessive social media use than boys, while boys are at greater risk of excessive gaming and gambling. The associations with known risk factors are somewhat different for excessive use of social media as compared to excessive gambling and gaming and should be acknowledged when developing preventive measures for adolescents.

Effectiveness of a Brief Group Intervention Program for Young Adults with Gaming-Related Problems

Excessive digital gaming can have unfavorable effects on gamers’ well-being and everyday functioning. The aims of this study were to investigate the effects of a novel group intervention “Limitless Gaming Bootcamp” on (i) gaming disorder (GD) tendencies, (ii) the amount of time spent on leisure activities, and (iii) subjective well-being among Finnish young adults, and to determine the persistence of the intervention’s influence over time. A one-group pre- and post-test design with no control group was used. Thirty-seven participants were enrolled in the study. The inclusion criteria were being between the ages of 18 and 29; self-reported excessive gaming; a willingness to get support in monitoring one’s gaming behaviour; and a fluency in Finnish. Participants completed a 10-session group intervention designed to enhance conscious gaming behavior and well-being. Baseline, post-test, and six month follow-up measurements were conducted to gather data. Variables measured included background variables, gaming disorder tendencies (Problematic Online Gaming Questionnaire, POGQ), self-reported time spent on various leisure activities, and subjective well-being (Short Form of the Clinical Outcomes in Routine Evaluation Outcome Measure, CORE-SF/A). The time spent on gaming decreased from pre- to post-intervention measurement and further to the six month follow-up, and participants exhibited less severe GD symptoms during the post-intervention phase and six months after the intervention. Gradual improvements in subjective well-being were also observed. The group intervention was found to be particularly effective at reducing the severity of GD symptoms.

Development and validation study of Game Overuse Screening Questionnaire

The aim of this study was to develop a screening questionnaire to distinguish high-risk individuals associated with game overuse from casual internet users. Reliability, validity, and diagnostic ability were evaluated for the newly developed Game Overuse Screening Questionnaire (GOS-Q). Preliminary items were assessed by 50 addiction experts online and 30 questions were selected. A total of 158 subjects recruited from six community centers for internet addiction participated in this study. Finally, 150 people were used in the analysis after excluding eight non-respondents. GOS-Q, Young's internet addiction scale, and Korean scale for internet addiction were used to assess concurrent validity. Internal consistency and item-total correlations were favorable (α= 0.96, r= 0.47-0.82). Test-retest reliability was moderate in size (r= 0.74). GOS-Q showed superior concurrent validity, and the highest correlation with Y-Scale (r= 0.77). The construct validity was marginally supported by a six-factor model using exploratory factor analysis. The area under the Receiver Operating Characteristic curve was 0.945. The high-risk addiction group was effectively characterized by a cut-off point of 38.5, with a sensitivity of 0.87 and a specificity of 0.88. Overall, the current study supports the use of GOS-Q as a reliable screening tool in a variety of settings.
