Machine Learning(s) in gaming disorder through the user-avatar bond: A step towards conceptual and methodological clarity
Reply to: User-avatar bond as diagnostic indicator for gaming disorder: A word on the side of caution (2024)
Abstract
In response to our study, the commentary by Infanti et al. (2024) raised critical points regarding (i) the conceptualization and utility of the user-avatar bond in addressing gaming disorder (GD) risk, and (ii) the optimization of supervised machine learning techniques applied to assess GD risk. To advance the scientific dialogue and progress in these areas, the present paper aims to: (i) enhance the clarity and understanding of the concepts of the avatar, the user-avatar bond, and the digital phenotype concerning gaming disorder (GD) within the broader field of behavioral addictions, and (ii) comparatively assess how the user-avatar bond (UAB) may predict GD risk, by both removing data augmentation before the data split and by implementing alternative data imbalance treatment approaches in programming.
User-avatar bond as diagnostic indicator for gaming disorder: A word on the side of caution
Commentary on: Deep learning(s) in gaming disorder through the user-avatar bond: A longitudinal study using machine learning (Stavropoulos et al., 2023)
Abstract
In their study, Stavropoulos et al. (2023) capitalized on supervised machine learning and a longitudinal design and reported that the User-Avatar Bond could be accurately employed to detect Gaming Disorder (GD) risk in a community sample of gamers. The authors suggested that the User-Avatar Bond is a “digital phenotype” that could be used as a diagnostic indicator for GD risk. In this commentary, our objectives are twofold: (1) to underscore the conceptual challenges of employing User-Avatar Bond for conceptualizing and diagnosing GD risk, and (2) to expound upon what we perceive as a misguided application of supervised machine learning techniques by the authors from a methodological standpoint.
Abstract
Background
Attention deficit hyperactivity disorder (ADHD) and behavioral addictions (BAs) are highly comorbid but little is known about the effect of anti-ADHD medications on behavioral addiction symptoms. Thus, the aim of this naturalistic prospective study was to investigate the long-term changes on BAs symptoms among methylphenidate-treated adults with a primary diagnosis of ADHD.
Methods
37 consecutive adult ADHD outpatients completed a baseline and follow-up assessment of ADHD, mood and BAs symptoms (internet, shopping, food, sex addictions and gambling disorder) after one year of methylphenidate (flexible dose) treatment.
Results
Internet addiction test scores pre-treatment were significantly higher than post-treatment scores (p < 0.001). The same trend was seen for the shopping addiction (p = 0.022), food addiction scores (p = 0.039) and sex addiction scores (p = 0.047). Gambling disorder scores did not differ pre and post treatment since none of the included patients reported significant gambling symptoms at baseline. The rate of ADHD patients with at least one comorbid BA was reduced after methylphenidate treatment (51.4% vs 35.1%). The correlation analyses showed a moderate positive correlation between the changes in sluggish cognitive tempo symptoms, cognitive impulsivity, mood and anxiety symptoms and changes in internet addiction symptoms.
Conclusions
This is the first study showing that after one-year of treatment with methylphenidate, adult ADHD patients show a significant reduction on internet, food, shopping and sex addiction symptoms. Further controlled studies with larger samples should replicate these preliminary results and elucidate the role of methylphenidate and other moderator factors (such as concomitant psychological treatments or lifestyle habits changes) on BAs improvements.

University Rankings as the Postmodern Media Communication of Higher Education
Abstract
This research paper explores the intricate relationship between university rankings, mass democracy, and postmodernity, elucidating the societal shift in evaluating academic excellence. As higher education experiences mass democratization, rankings emerge as vital tools in the new information market, providing accessible metrics for an increasingly diverse audience. The concept of “medialization” underscores the impact of rankings on shaping public perception, as journalists, lacking deep understanding of academic intricacies, turn to rankings for clarity. Reactivity within universities to achieve higher ranking placements underscores the internal influence of external media-driven evaluations. The paper argues that postmodern relativism challenges traditional meritocracy, disrupting the established communicative status of universities. Amidst ongoing debates about the legitimacy of rankings, the research recommends embracing a communicative meritocracy as a strategic response, emphasizing the importance of universities actively shaping their narrative. The emergence of AI, exemplified by chatGPT, is identified as a potential transformative force, offering personalized information and challenging traditional ranking methodologies. The research concludes with a call for continuous self-reflection within ranking systems and universities amidst a changing higher education landscape.
Mainland China's 2021 restrictions on under-18s' video game time were imposed when older 2019 restrictions already applied: Omitting the historical regulatory context is misleading
Commentary on: Compliance and alternative behaviors of heavy gamers in adolescents to Chinese online gaming restriction policy (Zhou et al., 2024)
Abstract
Investigating the impacts of addiction policymaking following implementation is important. Effective policies should be considered for emulation elsewhere, whilst ineffective policies should be repealed. Zhou et al. (2024) reported how Mainland Chinese under-18s responded to the 2021 restrictions on their online videogame playtime, which were intended to curb online gaming addiction. However, Zhou et al. failed to mention that Mainland China had previously tried to achieve the same regulatory aim by imposing rules in 2019 that were more lenient than the 2021 rules but nonetheless restricted under-18s' gameplay time. These 2019 restrictions were neither acknowledged as crucial background in the introduction section nor accounted for by Zhou et al. when interpreting their results, thus giving readers the incorrect impression that the 2021 rules were the first ones introduced and that under-18s' gameplay time was not restricted at all prior to 2021. Importantly, Zhou et al.’s entire sample of young people therefore consisted not merely of ‘heavy gamers’ as they euphemistically described them as, but ‘counterplayers’ who actively contravened the 2019 rules. The misleading omission of this context is a major limitation and misrepresentation. The results should be interpreted accordingly and not overgeneralised.
Abstract
Background and aims
Conflicting findings have been reported for the longitudinal course of behavioral addictions, especially for social media addiction (SMA) and work addiction (WA). Therefore, evaluating whether these constructs are more trait-like or state-like might be informative. The aim of the present study was to examine the proportion of variance of SMA and WA symptoms (as defined by the components model of addiction) explained by trait and occasion-specific factors in addition to exploring cross-lagged relationships between SMA and WA.
Methods
Young adults from a representative sample who continuously used social media and worked at least 40 hours a week during the first three waves of the Budapest Longitudinal Study were included (N = 1,551; Females: 50.6%; Age: M = 27.7 years [SD = 4.40]). The Bergen Social Media Addiction Scale and the Bergen Work Addiction Scale were administered in all three waves.
Results
A latent state-trait model with a general trait factor was considered for both SMA and WA. Symptomatic variability in SMA was explained approximately equally by trait and state-like factors, while WA-related symptom variability was mostly attributed to state-like factors. SMA negatively predicted WA over time, while WA showed a positive cross-lagged effect on SMA.
Discussion and Conclusions
While the symptoms of WA were more state-like, the trait-like effects were stronger in SMA. Situational influences and previous symptom severities might have to be considered in the screening process.
Abstract
Interest in psychedelic research in the West is surging, however, clinical trials have almost exclusively studied synthetic compounds such as MDMA, ketamine, DMT, LSD, ibogaine, and psilocybin. To date, few clinical trials have utilized whole mushroom/plant material like Psilocybe mushrooms, Iboga, or Ayahuasca. Individuals participating in the Roots To Thrive Psilocybin-Assisted Therapy for End of Life Distress program were administered synthetic psilocybin, whole Psilocybe cubensis, and mycological extract on separate occasions and post-treatment interview transcripts were qualitatively analyzed to discern themes and patterns. There was broad consensus that all three forms were helpful and similar, all generating visual and perceptual distortions, emotional and cognitive insight, and mystical experiences. However, synthetic psilocybin was said to feel less natural compared to organic forms, and the overall quality of experience of synthetic psilocybin was inferior to the organic forms. Research should be conducted with whole psychedelic mushrooms and extract in addition to synthetic psilocybin given this preliminary data, especially when considering that medicine keepers around the world have utilized whole mushrooms and plant material for millennia.
Az affektív érintés (simogatás) pszichofiziológiája. Narratív összefoglaló
Psychophysiology of affective touch (stroking). A narrative review
Elméleti háttér: Az affektív érintés (azaz a szőrös bőrfelület lassú simogatása) humán hatásaival kapcsolatos pszichológiai és pszichofiziológiai tudásanyag az elmúlt két évtizedben megtöbbszöröződött. Cél: Narratív összefoglalónk célja e friss empirikus tudásanyag, valamint az azt magyarázó elméletek bemutatása. Eredmények: Az empirikus eredmények az affektív érintés akut fájdalomcsillapító és stresszcsökkentő hatását sugallják. Az érintést közvetítő receptorok aktivitása emellett hozzájárulhat a testséma fenntartásához. Jelentős egyéni különbségek mutatkoznak az affektív érintésre való fogé- konyságban (az érintés észlelt kellemességében), ezek mögött részben a kötődési stílus különbségei húzódhatnak meg. Következtetések: Evolúciós szempontból az affektív érintés a homeosztázis fenntar- tásának szociális eszközeként közelíthető meg, csecsemőkortól egészen felnőttkorig.
