RESUMEN
INTRODUCTION: Despite the growing recognition of gaming disorder as a mental disorder, there is still debate about how it should be best screened for. This is especially relevant in countries where prevalence studies that could support evidence-based policymaking are still to be conducted. This study aims to evaluate the psychometric properties of the Brazilian Portuguese version of the Ten-Item Internet Gaming Disorder Test (IGDT-10) and to explore its association with functional impairment. METHODS: An online convenience sample of 805 Brazilian adults who reported playing games completed the adapted version of IGDT-10 and World Health Organization Disability Assessment Schedule 2.0, as well as the Problematic Internet Use Questionnaire, the Center for Epidemiologic Studies-Depression Scale, the Rosenberg Self Esteem Scale and socio-demographic questions. RESULTS: The Brazilian Portuguese version of IGDT-10 demonstrated a unidimensional structure in both confirmatory and exploratory factor analysis, with satisfactory internal consistency and adequate temporal stability. Participants who scored five or more on IGDT-10 presented higher levels of functional impairment compared to those who scored positive for four symptoms or less. The difference between the two groups was statistically significant and showed a moderate effect size. Network analysis showed a direct connection between IGDT-10 and functional impairment, and identified "negative consequences" as the most relevant item connecting these variables. CONCLUSION: The IGDT-10 is a brief, easy-to-understand, valid, and reliable instrument, proving to be a suitable candidate for screening gaming disorder in future epidemiological studies.
RESUMEN
Objectives: Video game addiction has been associated with an array of mental health variables. There is a paucity of longitudinal studies investigating such associations, and studies differentiating addicted gaming from problem and engaged (i.e., frequent but non-problem) gaming. The current explorative study investigate the natural course of gaming behavior in three sub-studies. The aim of study 1 was to investigate antecedents and consequences of video game addiction measured as a unidimensional construct (pathological gaming). Aim of study 2 was to investigate the same associations in terms of typologies of gamers ("engaged," "problem," "addicted"). Furthermore, study 3 aimed to investigate the estimated stability and transitions occurring between the aforementioned typologies, and a non-pathological gaming group. Methods: A nationally representative sample of 3,000 adolescents aged 17.5 years was drawn from the population registry of Norway in 2012 and invited to participate in annual surveys spanning 3 years (NT1 = 2,059, NT2 = 1,334, NT3 = 1,277). The respondents completed measures of video game addiction, depression, anxiety, loneliness, aggression, and alcohol use disorder. Statistical analysis comprised cross-lagged path modeling, Satorra-Bentler chi square test (study 1), regression analyses (study 2), hidden Markov model of transition probabilities (study 3). Results: Findings in study 1 showed that depression and loneliness were reciprocally associated with pathological gaming. Physical aggression was identified as an antecedent, and anxiety was a consequence of pathological gaming. Investigation of the three typologies of gamers (study 2) identified loneliness and physical aggression as antecedents, and depression as a consequence of all typologies. Depression was found to be an antecedent of problem and engaged gamers. Loneliness was found as a consequence of problem gamers, and anxiety was a consequence of addicted gamers. High alcohol consumption was found antecedent to addicted gamers, and low alcohol consumption was found antecedent to problem gamers. The estimated stability of video game addiction was 35%. Conclusion: A reciprocal relationship between pathological gaming and measures of mental health problems seems to exist. The stability of video game addiction indicates a condition that for a substantial number of people does not resolve spontaneously over the course of 2 years.
RESUMEN
Background and aims Excessive use of video games among children and adolescents is a growing concern. The aim of this study was to investigate the effectiveness of a brief parental guide with advices and strategies for regulating video gaming in children. Methods A random sample of guardians of children between the age of 8-12 years old (N = 5,864) was drawn from the Norwegian Population Registry and equally randomized into an intervention and a control condition. A parental guide based on clinical and research literature was distributed by postal mail to those in the intervention condition. A 4-month follow-up survey comprising questions about problematic video gaming, gaming behavior, sleep activity, and parental video game regulation behavior was administered. Results Independent t-tests revealed no significant differences between the two conditions (N = 1,657, response rate 30.1%) on any outcome measure. An ANOVA with planned comparisons showed that respondents who reported that they had read and followed the parental guide reported more video game problems and used more parental mediation strategies than those who did not read and follow the guide. Conclusions We found no evidence for the effectiveness of the psychoeducational parental guide on preventing problematic video gaming in children. However, the guide was read and positively assessed by a significant proportion of guardians. Differences between those who studied the guide and those who did not may indicate that parental guides are better aimed at providing important information to those who already have problems rather than as a mean of primary prevention.
