A longstanding challenge in the behavioral addictions field has been determining the point at which gaming involvement becomes clinically significant problematic use. Gaming disorder (GD) and hazardous gaming as recent ICD-11 diagnoses have attracted polarized perspectives due in part to the global popularity of recreational gaming and gaming culture. The broad continuum of gaming can often be perceived differently by different parties, including gamers themselves; what might be seen as regular, harmless, and normative to some, may be considered risky and problematic by others. The ICD-11 guidelines provide some clarity by advising that gaming disorder should not be diagnosed based on persistent gaming alone; that gaming as part of a routine, developing skills, changing mood or relieving boredom, or facilitating social interaction is not sufficient for a diagnosis; and that cultural and peer group norms should be considered in diagnosis. In this paper, we examine gaming normality-disorder boundary issues in the areas of conceptualization, assessment, and interventions. Some examples of the complex personal, social, and cultural considerations that arise in gaming diagnoses are provided. We call for researchers in the addiction and health disciplines to grapple with conceptual controversy and conduct the empirical and clinical research needed to ensure that normal recreational gaming is always clearly distinguished from harm and disorder.

Background and aims: There is a lack of research on the impact of acute stress on the interaction of affective and cognitive processes in online compulsive buying-shopping disorder (CBSD). Therefore, this project addressed stress response, cue reactivity, attentional bias, and implicit associations in individuals with online CBSD.

Methods: Women with CBSD (n = 63) and women with non-problematic online buying-shopping (n = 64) were randomly assigned to the Trier Social Stress Test or a non-stress condition. After the stress/non-stress induction, participants performed a cue-reactivity paradigm, a dot-probe paradigm, and an implicit association task, each with addiction-related (online buying-shopping) and control (social networks) cues.

Results: Individuals with CBSD showed stronger affective responses towards the addiction-related and control cues than the control group and rated the addiction-related pictures with higher 'arousal' and 'urge' than the control images. No group differences emerged in the dot-probe paradigm and implicit association task. Acute stress showed no effect on performance in the behavioural tasks. Regression models investigating the impact of craving on the relationship between stress response and implicit cognitions within the group with CBSD were not significant.

Discussion: The findings demonstrate the involvement and generalization of cue reactivity in online CBSD, but do not provide support for effects of acute stress on cue reactivity, attentional bias and implicit associations.

Conclusions: Future studies should not be restricted to women and combine laboratory and naturalistic study designs to investigate the complex psychological mechanisms in online CBSD.

Background and aims: Online dating applications (ODAs) are gaining popularity, raising concerns about their potential addictive effects on users' health. The main objective of this study was to investigate the association between problematic ODA use and mental health, substance use, and sexual behavior outcomes in men-who-have-sex-with-men (MSM). To achieve this, we first validated a German version of the Problematic ODA Use Scale (PODAUS), which assesses problematic ODA usage patterns.

Methods: Problematic ODA use was assessed in 226 HIV-negative MSM counseling for HIV pre-exposure prophylaxis at baseline and 6-month follow-up (n = 164, Mage = 42, SD = 11). The German PODAUS was validated using confirmatory factor analyses (CFA) and correlational analysis. Multiple linear regression analyses were performed to investigate associations of PODAUS with mental, sexual health, and substance use outcomes.

Results: CFA supported PODAUS' 6-item unidimensional structure, demonstrating excellent fit indices. Reliability analyses indicated good internal consistency (α = 0.79) and high test-retest reliability (rs = 0.68). Regarding mental health, significant positive associations were found between PODAUS and symptoms of depression, loneliness, anxiety, Attention Deficit Hyperactivity Disorder (ADHD), and impulsivity, with medium to large effect sizes. Regarding sexual health, significant negative associations of small to medium effect sizes were found between PODAUS and lifetime prevalence of sexually transmitted infections, body acceptance, and sexual fulfillment, while a significant positive association with trait sex motivation occurred.

Discussion and conclusion: The German version of PODAUS emerges as a valid, reliable tool to assess problematic ODA use. In an MSM sample, problematic ODA use was associated with lower mental and sexual health.

Objective: To explore the individual and interactive associations between mobile gaming addiction (MGA), excessive consumption of sugar-sweetened beverages (SSBs), and overweight/obesity among schoolchildren, and to investigate whether these interactions vary by gender or grade level.

Methods: Data were drawn from the Children's Growth Environment, Lifestyle, and Physical and Mental Health Development project (COHERENCE) conducted in Guangzhou, China, during the 2019/20 academic year. 418,197 children aged 6-12 years were included in the study. All participants were asked to complete an eligible questionnaire to provide details of their MGA over the past three months and SSBs consumption over the past week. Multiplicative and additive interaction models were performed to evaluate the interaction effects of MGA and excessive SSBs consumption on overweight/obesity, and variations by gender and grade level were also examined.

Results: Excessive SSBs consumption was identified as a risk factor for childhood overweight/obesity, but MGA was not. However, the combination of MGA and excessive SSBs consumption was associated with an increased risk of overweight/obesity. This multiplicative interaction was significantly stronger in girls than in boys, with no differences observed across grade levels. Additionally, the additive interaction effect between MGA and excessive SSBs consumption was present only in girls and children in the lower elementary grades.

Conclusions: This cross-sectional study found that the combination of MGA and excessive SSBs consumption is linked to an increased risk of childhood overweight/obesity, particularly in girls and children in lower elementary grades. These findings highlight the importance of addressing these factors together in targeted interventions.

Background and aims: There are limited data regarding associations between gaming disorder and physical activity (PA). The present study investigated the direct association between these two variables and assessed the potentially mediating roles of PA avoidance and two types of weight stigma (i.e., internalized weight stigma and perceived weight stigma) in the association.

Methods: An online cross-sectional survey that assessed PA avoidance, two types of weight stigma, and PA level was completed in late 2023 by 884 Taiwanese young adults aged between 20 and 40 years (63.9% females). Multinomial logistic regression and structural equation modeling (SEM) were used to assess the associations between variables and perform the mediation analysis.

Results: Cognitive behavioral symptoms and negative consequences related to gaming disorder were more common among participants with lower PA than those with moderate to high PA. Individuals at risk of gaming disorder exhibited higher level of PA avoidance, internalized weight stigma, and perceived weight stigma. The SEM found a direct association between gaming disorder and PA, which was negatively mediated by PA avoidance. However, this direct effect was not present when the association was negatively mediated by serial mediations of weight stigma and PA avoidance.

Discussion and conclusions: Higher gaming disorder was associated with higher levels of PA, but this association may not be present when taking into account the mediation effect of weight stigma and PA avoidance. The findings suggest complex relationships and further research is needed to examine individual differences and relationships among clinical groups.

Background and aims: Behavioral addictions (BAs) represent complex and multifaceted disorders often associated with maladaptive neural alteration. To deepen our understanding of the essence of BAs, this study focuses on the neural mechanisms underlying its three stages: reward seeking, self-control, and decision-making. The aim of the current meta-analysis is to investigate the brain regions and neural networks involved in BAs.

Methods: Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically searched for relevant articles published before September 1, 2024, in the Web of Science and PubMed databases, and supplemented our search with Google Scholar. We conducted analyses using activation likelihood estimation (ALE) meta-analysis and meta-analytic connectivity modeling (MACM) analyses.

Results: A total of 50 functional magnetic resonance imaging studies involving 906 participants were included. The findings showed that individuals with BAs exhibited hyperactivation in the right inferior frontal gyrus (IFG), bilateral caudate and left middle frontal gyrus (MFG), and a high degree of connectivity was found between the right caudate, left caudate, and right IFG. These findings indicated that BAs were associated with the fronto-striatal circuits. Individuals with BAs demonstrate specific neural activation patterns in the reward seeking, self-control, and decision-making stages, characterized by differences in activation and functional connectivity of brain regions associated with these stages.

Discussion and conclusions: This study verifies the pivotal role of the fronto-striatal circuits in BAs and highlights the specific patterns of brain activity in different stages of addictive behavior. These findings expand our understanding of neural mechanisms underlying BAs and supports and provide partial support for the I-PACE model.

Background: Food addiction and an impulsive personality can increase overeating, which can lead to weight gain. The amygdala and nucleus accumbens (NAcc) are critical for regulating obesogenic behaviour. However, whether the amygdala or the NAcc acts as the neural basis for the regulation of food addiction, impulsive personality, and body weight remains unclear.

Methods: We examined the differences in the volume of the amygdala and NAcc, especially the lateralization index (LI), between 33 obese participants and 39 age- and sex-matched healthy controls. The associations of the LI of each brain region with clinical variables and body mass index (BMI) were identified using network analysis. Finally, we explored the relationships among the LIs of brain regions, impulsive personality, food addiction, and BMI through a multiple chain mediation model.

Results: We observed a significant decrease in the LI of the amygdala in the obese group compared with the healthy group (F = 20.276, p < 0.001), which indicates that the right amygdala was larger than the left amygdala in the obese group. Network analysis revealed that the LI of the amygdala was very closely associated with nonplanning impulsivity, food addiction and BMI. The results of the mediation analysis indicated that increased nonplanning impulsiveness could lead to weight gain through increased food addiction (β = 0.069, SE = 0.043, 95% CI [0.014, 0.184]). Moreover, in this symptom chain, the LI of the amygdala can mediate the relationship between food addiction and BMI (β = 0.018, SE = 0.014, 95% CI [0.002, 0.061]).

Conclusion: Our observations indicate a substantial reduction in the LI of the amygdala among individuals with obesity, suggesting a structural predisposition. The findings reveal a potential neural mechanism that can help explain the interplay between impulsivity, food addiction, and obesity.

Aims: This study aimed to explore the brain activity characteristics of individuals with Internet Gaming Disorder (IGD) during mobile gameplay, focusing on neural responses to positive and negative game events. The findings may enhance our understanding of the neural mechanisms underlying IGD.

Methods: Functional near-infrared spectroscopy (fNIRS) was employed to measure hemodynamic responses (HbO/HbR) in the prefrontal cortex of both IGD participants and recreational gaming users (RGU), during solo and multiplayer mobile gameplay.

Results: In solo mode, IGD participants exhibited stronger activation in the dorsolateral prefrontal cortex (dLPFC), frontopolar area (FPA), orbitofrontal cortex (OFC) in response to positive events compared to RGU. Negative events led to reduced activation in the FPA among IGD participants. In multiplayer mode, IGD participants displayed lower activation in the dLPFC and ventrolateral prefrontal cortex (vLPFC), although overall brain response trends to positive and negative events were similar between IGD and RGU.

Conclusions: This study suggests that individuals with IGD exhibit heightened sensitivity to rewards and diminished sensitivity to losses, along with potential impairments in the executive control network. These results contribute to a better understanding of the neural mechanisms of IGD and offer insights for developing targeted interventions aimed at addressing abnormal reward and loss processing.

Background and aims: Sexual trauma is associated with multiple negative health and social conditions, including compulsive sexual behavior. The present study examined network structures involving sexual trauma history, psychological distress (defined as depression and/or anxiety symptoms), substance use, transactional sex, and compulsive sexual behavior. Prior network analysis work in this area is limited.

Methods: We drew upon two samples of young adults (Sample 1: n = 1,884, 69.3% women; Sample 2: n = 2,337, 69.7% women) recruited from universities in the United States in 2020-2022.

Results: Findings support relationships between sexual trauma and compulsive sexual behavior. Relationships between elements of compulsive sexual behavior, timing of trauma, psychological distress, substance use, engagement in transactional sex, and gender differences were identified. Significant edge strength differences between men and women were observed; distress was a more central node for men, trauma was a more central node for women (Sample 1). When examining elements of CSB, significant gender differences in edge strength were also observed (e.g. connections between dissatisfaction and relapse for men, dissatisfaction and negative consequences for women).

Discussion and conclusions: Specific aspects of CSB closely related to sexual trauma history (e.g., dissatisfaction) and co-occurring psychopathology or clinical concerns (e.g., depression, anxiety, substance use, and engagement in transactional sex) and warrant further attention and study.

Background and aims: The widespread popularity of video games reflects their appeal to meet fundamental needs. This study aims to investigate the psychological factors of gaming use, identifying profiles ranging from healthy to gaming disorder.

Methods: In this cross-sectional study, 5,222 participants were surveyed. This international sample included adolescents and adults (16-69 years, M = 25.6 years, SD = 6.44), 48.66% men (n = 2,541; M = 26.4, SD = 7.03), 42.32% women (n = 2,210; M = 25.1, SD = 5.78), and 9.02% non-binary individuals (n = 471; M = 23.3, SD = 5.23), spanning from casual gamers to esports professional players. Latent Profile Analysis (LPA) was employed to identify distinct psychological profiles. The profile indicators included emotional regulation and motivations for playing video games. The profile correlates analysed included gaming disorder symptoms, time spent gaming and sociodemographics.

Results: The LPA revealed four profiles labelled as avoidant (20.16%), engaged (38.95%), relational (26.01%), and dysregulated (15.78%). Results suggested that the dysregulated profile had the most emotional regulation difficulties, a low level of general motivation, and less interest in recreational gaming, presenting the highest risk for gaming disorder.

Discussion and conclusions: This study's findings present the first profiles encompassing key detailed psychological factors affecting gamers' behaviour across all game genres, considering three genders. These profiles can aid researchers and clinicians in developing further research on targeted prevention and intervention programs tailored to each profile's characteristics to promote healthy gaming habits and mitigate the risks and harm associated with gaming disorder.
