Interplay between alexithymia, emotion regulation, and positive and negative affect as predictors of gambling and gaming disorders in adolescents and young adults

Introduction/Objectives: Gambling and gaming disorder are usually comorbid addictive behaviours in which alexithymia and emotional regulation have been proved to be of relevance. The present study aimed to analyse the relationship between those variables and their differences depending on the presence or absence of gambling and gaming behaviours. Method: The sample consisted of 1,219 people between 12 and 20 years of age (M = 15.55, SD = 2.07; 51.8% females). Results: The results showed significant differences between players and non-players in gambling disorder, alexithymia and emotional regulation. The findings also indicated that there were differences in alexithymia, emotional regulation, negative affect, gambling disorder and gaming disorder among the different profiles of video game players. The comparison of participants with gaming disorder, gambling disorder, both, or neither of them, showed differences in alexithymia, emotional regulation, negative affect, gambling disorder and gaming disorder. Furthermore, correlations between gambling disorder and age, gaming disorder, negative affect, alexithymia and emotional regulation were found. Similarly, gaming dis-order was associated with gambling disorder, negative affect, alexithymia, emotional regulation and age. Conclusions: The hierarchical regression analyses demonstrated the predictive role of alexithymia and age in gambling disorder as well as the predictive role of age, sex and negative affect in gaming disorder.

Prevalence of internet gaming disorder and its psychological correlates / Prevalência do transtorno do jogo pela internet e seus correlatos psicológicos

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

INTRODUCTION: Mobile video gaming among university students has increased rapidly, more than before the COVID-19 pandemic. This is very concerning as this could spark various problems, such as musculoskeletal pain and gaming disorders. OBJECTIVES: The present study is to identify the predictors of mobile video gaming on musculoskeletal pain among university students in Selangor, Malaysia. PARTICIPANTS AND METHODS: This study was conducted online using a self-reported online questionnaire via Google Form and sent to university students in Selangor, Malaysia. Participants' gaming addiction was measured using the Ten Item Internet Gaming Disorder Test (IGDT-10) questionnaire, and the prevalence of musculoskeletal pain was assessed by the Modified Nordic Musculoskeletal Questionnaire (MNMQ). The data was analyzed using SPSS version 25. A descriptive and binomial linear regression test was used to predict the variables. The statistical significance was set at p < 0.05, and odds ratios were calculated with confidence intervals of 95%. RESULTS: The prevalence of Internet Gaming Disorder among university students in Selangor, Malaysia is 1.8% (n=3). The neck region (74.2%) was the most commonly reported body region with musculoskeletal pain, followed by the shoulder region (60.7 %), lower back region (55.8 %), and upper back region (50.9 %). The body position was the only predictor of mobile video gaming with musculoskeletal pain (p = 0.002) in the lower back region. CONCLUSION: According to the findings of this study, the prevalence of Internet Gaming Disorder (IGD) among university students was low and not addicted to gaming in the Covid-19 lockdown. We also found that participants who sat while playing mobile video games were more likely to develop low back pain. However, one of the limiting factors could be prolonged sitting in virtual classes during the lockdown, which causes low back pain.

Predictors of gaming disorder in children and adolescents: a school-based study

Objective: To determine whether psychiatric and gaming pattern variables are associated with gaming disorder in a school-based sample. Methods: We analyzed data from the Brazilian High-Risk Cohort for Psychiatric Disorders, a community sample aged 10 to 18, using questionnaires on gaming use patterns. We applied the Gaming Addiction Scale to diagnose gaming disorder and the Development and Well-Being Behavior Assessment for other diagnoses. Results: Out of 407 subjects, 83 (20.4%) fulfilled the criteria for gaming disorder. More role-playing game players were diagnosed with gaming disorder that any other genre. Gaming disorder rates increased proportionally to the number of genres played. Playing online, being diagnosed with a mental disorder, and more hours of non-stop gaming were associated with higher rates of gaming disorder. When all variables (including age and gender) were considered in a logistic regression model, the number of genres played, the number of non-stop hours, the proportion of online games, and having a diagnosed mental disorder emerged as significant predictors of gaming disorder. Conclusion: Each variable seems to add further risk of gaming disorder among children and adolescents. Monitoring the length of gaming sessions, the number and type of genres played, time spent gaming online, and behavior changes may help parents or guardians identify unhealthy patterns of gaming behavior.

Factors Correlated With Internet Gaming Disorder Among Malaysian University Students

@#Introduction: Internet gaming disorder (IGD) has recently been incorporated into the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) as a disorder for future research. The primary objectives of the present study are to describe the level of IGD and to examine its correlations with sociodemographic factors and psychological comorbidities among undergraduate students in a Malaysian university. Methods: A total of 411 undergraduate students completed an online questionnaire. They were selected from a random sample of participating university faculties. The online questionnaire contained the Internet Gaming Disorder Scale-Short-Form and the Depression, Anxiety, Stress Scale. Results: The presents study reported that 52.8% of the participants had high IGH. Using hierarchical multiple regression, age (β = -0.09, p < 0.05), gender (β = -0.40, p < 0.001) and stress (β = 0.23, p < 0.05) were statistically significant predictors of IGD. Academic performance, depression and anxiety did not emerge as significant predictors. Conclusion: These findings highlight the risk factors (in particular, stress) of IGD. Further studies on interventions, particular that of preventative strategies, will be needed to combat this emerging public health problem.

Cross-cultural adaptation of the Internet Gaming Disorder Scale - Short Form (IGDS9-SF) to the Brazilian context

Abstract Introduction The Internet Gaming Disorder Scale - Short Form (IGDS9-SF) assesses the severity, harmful effects and/or consequences of excessive online and offline gaming. Its conciseness and theoretical foundations on current diagnostic criteria of gaming disorders make it a useful resource for clinical and screening settings. Objective To describe the process of cross-cultural adaptation of the IGDS9-SF to the Brazilian context. Methods The cross-cultural adaptation involved the steps of independent translation of the instrument, synthesis version, back-translation, pre-test and elaboration of the final version. Content validity assessment was conducted by a multidisciplinary committee of experts and consisted of both a quantitative analysis (calculation of content validity coefficients - CVC) and a qualitative analysis (assessment of the experts' comments and suggestions). The pre-test sample consisted of 30 gamers with variable sociodemographic characteristics. Results The cross-cultural adaptation of the scale followed the proposed protocol, and the CVC was satisfactory (≥ 0.83) for all the structures and equivalences assessed. Most of the suggestions made by the experts were accepted (mainly adjustments and language standardization). The gamers who participated in the pre-test judged the scale easy to understand and did not suggest changes. Discussion The Brazilian version of the IGDS9-SF showed adequate content validity and is available for researchers and clinicians, as well as for the investigation of additional psychometric characteristics.

La evidencia para el diagnóstico y el manejo del trastorno por juego en Internet está creciendo. Factores psicológicos y biológicos están involucrados en su etiopatogenia y estos factores pueden presentar diferentes niveles de contribución al trastorno dependiendo del género del paciente. Teniendo en cuenta que la tasa de individuos masculinos en comparación con la tasa femenina en el trastorno por juego en Internet es de aproximadamente 3:1 y que la mayoría de los estudios disponibles se realizan en poblaciones predominantemente masculinas, se realizó una revisión narrativa, no sistemática, centrada en literatura primaria y seleccionada de una búsqueda en las bases de datos PubMed y SciELO. Los términos clave que se utilizaron fueron los siguientes: "Internet Gaming Disorder" y "Internet Gaming Disorder and Gender". Todos los miembros del equipo de investigación participaron en la revisión de la literatura. Todo lo anterior se realizó a fin de presentar una imagen general sobre las diferencias de género en los juegos en línea, que pueda servir para mejorar los conocimientos de los trabajadores de la salud mental sobre este desafiante grupo de pacientes.

The body of evidence for Internet Gaming Disorder is growing. Both psychological and biological factors are involved in its etiopathogenesis and these factors may present different levels of contribution to the disorder depending on the gender of the patient. Taking into account that the rate of male individuals compared with the female rate in the Internet Gaming Disorder is about 3:1 and that most of the available studies are done in predominantly male populations, a non-systematic narrative review was done, focused on primary literature and selected from a search in PubMed and SciELO databases. The key terms used were: "Internet gaming disorder" and "Internet gaming disorder and gender". All members of the research team participated in the review of the literature. All the above was done in order to present a general picture about gender differences in online games, which can be used to improve the knowledge of mental health workers about this challenging group of patients.

Prevalence of internet gaming disorder in India: a technological hazard among adolescents

Background: Internet gaming disorder (IGD) refers to the problematic use of on-line or off-line video games. Presently the prevalence of IGD among the adolescent group was between 1.3% to 19.9% and males reported more prevalence than females. Aims of this study was to know the prevalence and the various factors associated with the development IGD among adolescents.Methods: Settings and Design was to a cross sectional study was conducted among students of High schools for a period of 3 months from July 2018 - September 2018. Four hundred adolescent students were included in the study. English version of the DSM–5 short (9-item) dichotomous scale with cut-off point of five or more criteria was used for diagnosing the IGD.Statistical analysis used descriptive statistics were represented with frequencies and percentages. Chi-square and Fisher Exact tests were applied to find significance difference. P<0.05 was considered as statistically significant.Results: An overall prevalence estimate of IGD was 3.50% among the school children and it is higher among male students (8.8%) than female students (0.8%) and it was found statistically significant with a p value of <0.001.Conclusions: The prevalence differences between Age groups, gender, class of the student and availability of smart phone with internet facility act as an important risk factors for the occurrence of IGD among adolescents.

Internet gaming disorder: a public health concern

Background: Internet gaming disorder is the public health concern globally due to its detrimental effects on the youth to an extreme of provoking them to suicide. As we lack studies in India highlighting this issue we have taken up a study to assess internet gaming disorder among medical graduates and validate the Internet gaming disorder-20 (IGD-20) scale. Methods: A cross-sectional study done on 200 first and second year medical students of Kurnool Medical College, Kurnool during February and March, 2019 using self-administered questionnaire containing IGD-20 which satisfies Griffith’s biopsychosocial component model and questions to assess socio behaviour changes. Data entered and analysed using SPSS version 23. Descriptive analysis, reliability tests, correlation and other appropriate significant tests used. Results: Prevalence of internet gaming disorder was 10%, more in male and who spend more than 30 hours per week on gaming which was statistically significant. Internal consistency of the IGD-20 was 0.91 Cronbach’s alpha. Socio-behavioural changes like aggressiveness, irritability and change in food patterns were significantly associated with excessive disordered gaming habit. Conclusions: Advanced technology as electronic gadgets, easily accessible networks are attracting the generation and making them addicted to it. Stress of the competitive world, loneliness is triggering this behaviour. Timely detection and management of the disordered gamers, scrutiny of parents on the internet gaming usage pattern of their kids, self-realisation and motivation towards physical games could help the youth to succumb the internet gaming disorder.

Research progresses on cognitive function and neuroimaging study of internet gaming disorder / 中国医学影像技术

With the rapid development of internet technology, internet gaming disorder (IGD) has become a global mental health problem. At present, most of the researches on IGD focus on three aspects, i.e. reward system, suppression control and intertemporal decision-making. With the development of cognitive neuroscience, it becomes popular to use electroencephalogram (EEG), MRI and PET in exploring the neural mechanism of IGD. Previous neuroimaging studies have shown that brain structure and function of IGD patients both changed accordingly compared with healthy controls. Besides, the degree of brain damage is related to the duration of addictive behavior. The recent work in cognitive function and neuroimaging researches of IGD were reviewed in this article, highlighting research methods and corresponding results, in order to provide references for further exploration and scientific research in this area.

The abnormal cognitive function and neural mechanism of individuals with internet gaming disorder / 中华行为医学与脑科学杂志

Internet gaming disorder (IGD) refers to individuals who are extremely dependent on online games and can’t control the game time reasonably.Generally, individuals with IGD also display withdrawal symptoms when they do not play games.Combined with previous studies, this paper discussed the cognitive dysfunction and neural mechanisms of IGD individuals, including executive function, reward system and emotional regulation dysfunction.First of all, executive function is a high-level cognitive processing ability that involves cognitive and behavioral processes.Cognitive control is often associated with the individual's goal-directed behavior and the ability to flexibly apply the high-level cognitive function. Repeated and excessive game behaviors of IGD individuals may be associated with their abnormal cognitive control and decision-making functions. And the attention process as another important component of executive function. The persistent addictive behavior in individuals with IGD were associated with a bias toward attention to game-related cues.Also, IGD individuals show differences in executive function abnormalities such as decision-making and dominance response inhibition, suggesting that there is a separation between "cold" and "hot" executive function abnormalities, and this feature may also be associated with other cognitive dysfunctions. Secondly, reward incentives play an important role in individual motivational learning and goal-oriented behavior. The increased sensitivity of IGD individuals to reward stimuli in various types of reward and punishment stimuli suggests that their reward system is abnormal.Finally, emotional regulation is an important cognitive function that is closely related to executive function. The anxiety and depression manifested by IGD individuals are often associated with their inability to apply emotional regulation strategies flexibly. It is difficult for individuals with IGD applied emotional regulation strategies flexibly, and inappropriate emotional regulation strategies and emotional responses suggest abnormal mood regulation. To sum up, cognitive dysfunction was not only the basis of IGD addiction symptoms, but also one of the important factors of its symptom maintenance. In addition, the further research prospects included expanded sampling population, deepening neural mechanism research and physical intervention are proposed for the lack of previous research in the last part of the article.

The Relationship between Depression, Attention Deficit/Hyperactivity Disorder, and Internet Gaming Disorder Through Mediation Model

OBJECTIVES: Internet gaming disorder (IGD) is associated with attention deficit/hyperactivity disorder (ADHD) or depression etc. We tried to examine the mediating effects of depression in the relationship between ADHD and IGD.METHODS: This study was conducted on 2000 people who participated in on-line survey among 14–39 year-old men and women in 2017. And we clarified the relationship among IGD, ADHD, and depression and tested the mediation model. The mean and standard deviation of the main variables were calculated and correlation analysis was performed to confirm the relationship among the main variables. In order to test the mediating effect of depression on the relationship between ADHD and IGD, the structural equation model was implemented using AMOS 21 (IBM).RESULTS: There were significant correlations among the variables; IGD, ADHD and depression. Depression had a mediating effect 0.23 (95% confidence interval : 0.17–0.28) in the relationship between IGD and ADHD.CONCLUSIONS: This study showed that depression can mediate ADHD and IGD. Therefore, the evaluation and management of depression and ADHD should be included in the diagnosis and treatment of IGD.

Addiction and Quantitative Electroencephalography / 신경정신의학

Quantitative electroencephalography (QEEG) has a long history and its clinical usefulness has gradually become well known. QEEG is a noninvasive, easy, comfortable and inexpensive way to check the brain status, but it is not specific to a diagnosis and requires sufficient experience in its clinical interpretation. The techniques and parameters of QEEG are increasingly being developed and studied, so their utilization will become more widespread in the future. QEEG in addiction disorders has not been fully studied, but it has many possibilities. The symptoms of addiction disorder and QEEG characteristics in some addictions show features that are clinically beneficial to diagnosis and treatment. Various complementary studies in the future are expected to make it more useful in clinics.
