•Research on video game design and dysregulated gaming needs further development.•Research directions must shift from linear causal approaches to interactionist ones.•Relevant research directions, with examples of suitable study designs, are proposed.

Burden of gaming disorder among adolescents: A systemic review and meta-analysis

Objectives

Integrating digital technology into daily life has made video games a primary form of entertainment for adolescents worldwide. Despite their benefits, excessive gaming has emerged as a significant public health issue, recognized as a gaming disorder by the World Health Organization in the ICD-11. This study aims to assess the prevalence of gaming disorders among adolescents through a systematic review and meta-analysis.

Study design

Systematic review and meta-analysis.

Methods

A search was conducted across multiple databases until February 15, 2024. Observational studies that assessed the prevalence of gaming disorder were included. Nested Knowledge software was used for screening and data extraction. The quality assessment was performed using the Joanna Briggs Institute tool. Meta-analysis using a random effect model was used to synthesize prevalence rates. Statistical analyses were performed in R software version 4.3.

Results

The meta-analysis included 84 studies covering a diverse geographical scope totaling 641,763 individuals. The pooled prevalence of gaming disorder was 8.6 % (95 % CI: 6.9 %-10.8 %), (I2 = 100 %). Subgroup analysis revealed varying prevalence rates by country, with China reporting the highest rate at 11.7 % (95 % CI: 8.6 %-15.7 %). Meta-regression analysis highlighted an increasing trend in the prevalence of gaming disorder over the years, underscoring the growing impact of digital technologies.

Conclusion

A significant prevalence of gaming disorder among adolescents is observed. With an increasing trend, fostering healthy gaming habits, enhancing awareness, and implementing effective intervention programs are crucial. This emphasizes the importance of global efforts in combating the growing challenge of gaming disorder among adolescents.

The Role of Videogame Micro-Transactions in the Relationship Between Motivations, Problem Gaming, and Problem Gambling

Emerging research has highlighted potential associations between micro-transaction use and problematic videogame and gambling behaviour. An increasingly prominent theory highlights that self-determined motivations and basic psychological needs may play crucial roles in the development of problematic videogame and gambling behaviour. However, literature discussing the role that micro-transaction use has in this relationship is scarce. The present study examined the role of micro-transactions in the relationship between self-determined motivations for gaming and gambling and problematic behaviour (internet gaming disorder and problem gambling severity). A sample of 370 participants (74.1% male, Mage = 28.24 years, SD = 7.88) answered questions related to their gaming and gambling motivations, basic psychological needs, micro-transaction use (i.e., type of micro-transaction, expenditure, and frequency of use), internet gaming disorder, and problem gambling. The present study used structural equation modelling methods to test relationships between these variables. The results indicated positive associations between extrinsic gaming and gambling motivations and frequency of micro-transaction use. Frequency of micro-transaction use (i) partially mediated the relationship between extrinsic gambling motivations and problem gambling severity, and (ii) fully mediated the relationship between externally regulated gaming motivations and problem gambling severity. Expenditure on micro-transactions and basic psychological needs were not found to be significant variables in the present study. Potential explanations for the findings, including a lack of self-esteem and a need to boost ego, social pressure, and rapid reward processes, are discussed. The implications and applications of the research are also discussed, focusing on limit setting and policy development focusing on frequency of micro-transaction use.

Propensity for risky choices despite lower cue reactivity in adolescent rats

Adolescence is a time of heightened risk-taking across species. Salient audiovisual cues associated with rewards are a common feature of gambling environments and have been connected to increased risky decision-making. We have previously shown that, in adult male rats, sign tracking - a behavioral measure of cue reactivity - predicts an individual's propensity for suboptimal risky choices in a rodent gambling task (rGT) with win-paired cues. However, adolescents perform less sign tracking than adult animals, suggesting that they are less cue-reactive than adults in some circumstances. Therefore, we investigated the performance of adolescent male rats on the rGT with win cues and examined its relationship with their sign-tracking behavior. We found that adolescents make more risky choices and fewer optimal choices on the rGT compared with adults, evidence of the validity of the rGT as a model of adolescent gambling behavior. We also confirmed that adolescents perform less sign tracking than adults, and we found that, unlike in adults, adolescents' sign tracking was unrelated to their risk-taking in the rGT. This implies that adolescent risk-taking is less likely than that of adults to be driven by reward-related cues. Finally, we found that adults trained on the rGT as adolescents retained an adolescent-like propensity toward risky choices, suggesting that early exposure to a gambling environment may have a long-lasting impact on risk-taking behavior.

Uncovering sample heterogeneity in gaming and social withdrawal behaviors in adolescent and young adult gamers in Hong Kong

OBJECTIVE

The current study aimed to examine the latent heterogeneity of gaming and social withdrawal behaviors in internet gamers and their associations with help-seeking behaviors.

METHOD

The present study recruited 3430 young people (1874 adolescents and 1556 young adults) in Hong Kong in 2019. The participants completed the Internet Gaming Disorder (IGD) Scale, Hikikomori Questionnaire, and measures on gaming characteristics, depression, help-seeking, and suicidality. Factor mixture analysis was used to classify the participants into latent classes based on their latent factors of IGD and hikikomori in separate age groups. Latent class regressions examined the associations between help-seeking and suicidality.

RESULTS

Both adolescents and young adults supported a 4-class, 2-factor model on gaming and social withdrawal behaviors. Over two-third of the sample were classified as healthy or low-risk gamers with low IGD factor means and low prevalence of hikikomori. Around one-fourth was moderate-risk gamers with elevated prevalence of hikikomori, higher IGD symptoms and psychological distress. A minority of the sample (3.8%-5.8%) belonged to high-risk gamers with the highest IGD symptoms and prevalence of hikikomori and heightened suicidal risks. Help-seeking in low-risk and moderate-risk gamers was positively associated with depressive symptoms and negatively associated with suicidal ideation. Perceived usefulness of help-seeking was significantly linked with lower likelihoods of suicidal ideation in the moderate-risk gamers and suicide attempt in the high-risk gamers.

CONCLUSIONS

The present findings explicate the latent heterogeneity of gaming and social withdrawal behaviors and associated factors on help-seeking and suicidality among internet gamers in Hong Kong.
