Aborder l'addiction au jeu sous l'angle de la question du jeu, tel est l'objectif de ce dossier qui rassemble des contributions issues de différentes disciplines (sociologie, psychologie, sciences de l'information et de la communication, littérature comparée), tournées vers différentes pratiques (jeux d'argent, jeux vidéo), elles-mêmes situées dans différents pays (de la France à la Chine en passant par la Finlande et d'autres pays européens), mais dont le point commun est cette attention particulière portée à la dimension addictive des pratiques ludiques. Sans jamais essentialiser ce lien que le jeu entretiendrait avec l'addiction – une notion issue du langage médical qu'il faudra d'ailleurs commencer par discuter –, il s'agit au contraire de remettre en question la nature de ce lien, en analysant tour à tour la façon dont il est conçu selon le contexte scientifique, politique et moral dans lequel la pratique s'inscrit, les enjeux socioéconomiques qui président à l'encadrement de cette pratique, la structuration des espaces sociaux dans lesquels elle prend place et les représentations de l'addiction au jeu telles qu'elles sont produites aussi bien par la littérature romanesque que par la presse quotidienne.

Cue reactivity is essential to the maintenance of addictive disorders. A useful way to study cue reactivity is by means of normative pictures, but few validated tobacco-related pictures are available. This study describes a database of smoking-related pictures: The Geneva Smoking Pictures (GSP). Sixty smoking-related pictures were presented to 91 participants who assessed them according to the classic emotional pictures validation provided by the International Affective Picture System (NIMH Center for the Study of Emotion and Attention, 2002). The pictures were rated according to three dimensions: (1) valence (from positive to negative), (2) emotional arousal (from high arousing to low arousing), and (3) dominance (from submissive to dominant). Participants were also screened with the Fagerström Test for Nicotine Dependence. Normative ratings for valence, arousal and dominance of the pictures are provided for the whole sample, as well as separately for dependent (n = 46) and nondependent smokers (n = 45). Arousal and dominance were associated with greater nicotine dependence, but valence ratings were not. The GSP is a normative database providing a large number of stimuli for investigators who are conducting nicotine and tobacco research.

Cannabis is the most popular psychoactive substance under international regulations, with more than 192 million users worldwide. It has been associated with an addictive pattern of use and negative social and health-related outcomes in a subgroup of users. Consequently, understanding the individual differences that contribute to cannabis use and problematic use is of much importance. The current study examined the impact of impulsivity traits (negative urgency, positive urgency, lack of premeditation, lack of perseverance, sensation seeking), delay reward discounting, and depressive mood on cannabis use status during the past 6 months as well as problematic use of cannabis in a representative sample of 635 French-speaking Swiss young men recruited during their conscription in a Swiss national military recruitment center. Binary logistic and multiple linear regressions indicated that cannabis use status was significantly associated with greater depressive mood, elevated sensation seeking, and lack of perseverance, whereas problematic cannabis use was significantly related to higher depressive mood and steeper delay reward discounting. The present study highlights the importance of emotional symptoms in cannabis use and misuse. Our results also shed light on the potential psychological processes related to problematic consumption of cannabis and open avenues for preventive actions and psychological interventions that target problematic use of cannabis.

<b><i>Objective:</i></b> To examine the association between adolescent at-risk or problem gambling (ARPG) and medicine used to treat nervousness in a large-scale nationally representative sample of Italian adolescents. <b><i>Study design:</i></b> Data from the 2013/2014 Health Behaviour in School-aged Children Survey was used for cross-sectional analyses (a sample of 20,791 15-year-old students). Self-administered questionnaires were completed by a representative sample of high-school students. Respondents' ARPG, use of medicine for nervousness and potential confounding factors were assessed. Multilevel logistic regression analyses were used to test the association between medicine use to treat nervousness and ARPG. <b><i>Results:</i></b> The overall prevalence of adolescents reporting medicine use for nervousness in the last month was 6.3%. The odds of ARPG were 3 times higher among adolescents who used medicine for nervousness compared to that among adolescents who did not take such medicine (OR 2.96, 95% CI 2.07-4.25). Importantly, the association between medicine used to treat nervousness and ARPG did not vary significantly when viewed in light of psychological symptoms. <b><i>Conclusions:</i></b> Medicine use to treat nervousness is associated with increased risk of gambling-related harm.

Video games as a consumer product have changed significantly with the advent of in-game purchasing systems (e.g., microtransactions, 'loot boxes'). This review examines consumer protections related to in-game purchasing by anticipating some of the potential design strategies that might contribute to higher risk consumer behavior. Attention was directed towards the analysis of patents for potential in-game purchasing systems, with 13 identified on Google Patents. The design features were analysed in relation to the consumer rights and guarantees described in the terms of use agreements of the patent assignees. The analysis revealed that some in-game purchasing systems could be characterized as unfair or exploitative. These systems describe tactics that capitalize on informational advantages (e.g., behavioral tracking) and data manipulation (e.g., price manipulation) to optimize offers to incentivize continuous spending, while offering limited or no guarantees or protections (e.g., refund entitlement), with the potential to exploit vulnerable players (e.g., adolescents, problematic gamers). These findings are critically discussed in relation to behavioral economics, addiction psychology, and the clinical conceptualization of gaming disorder. Appropriate policy and consumer protection measures, psychologically informed interventions, and ethical game design guidelines are needed in order to protect the interests and wellbeing of consumers.

<i>Background:</i> Several studies have linked massively multiplayer online role-playing games (MMORPGs) with possible problematic usage or internet addiction. <i>Aims:</i> The main goal of the present study was to assess links between motivations to play in MMORPGs and addictive involvement in such types of games. <i>Methods:</i> A total of 696 gamers responded to an online survey. <i>Results and Conclusion:</i> Five distinct motivations to play were identified in gamers: achievement, socializing, immersion, relaxing and escaping. Multiple regression analysis revealed that addictive MMORPG use patterns are predicted by achievement, escapism and socializing motives. Gender was also a significant predictor of problematic involvement in MMORPGs. Moreover, addictive MMORPG use positively correlated with the weekly time devoted to playing MMORPGs.

This study describes a new database of alcohol-related pictures: The Geneva Appetitive Alcohol Pictures (GAAP). 60 alcohol-related pictures (beverages, drinking-related behaviors, alcohol-related cues) were presented to 101 participants (ranging from social drinkers to problem drinkers), who assessed them according to the classic emotional pictures validation provided by the International Affective Picture System (Center for the Study of Emotion and Attention (CSEA[-]NIMH), 2002). Participants were also screened with the Alcohol Use Disorders Identification Test. Normative ratings for valence, arousal and dominance of the pictures are provided separately for problem/risky users (n = 49) and non-risky drinkers (n = 52). The GAAP is a normative database that provides a large number of stimuli for investigators who conduct research on alcohol.

The Internet is now all-pervasive across much of the globe. While it has positive uses (e.g. prompt access to information, rapid news dissemination), many individuals develop Problematic Use of the Internet (PUI), an umbrella term incorporating a range of repetitive impairing behaviours. The Internet can act as a conduit for, and may contribute to, functionally impairing behaviours including excessive and compulsive video gaming, compulsive sexual behaviour, buying, gambling, streaming or social networks use. There is growing public and National health authority concern about the health and societal costs of PUI across the lifespan. Gaming Disorder is being considered for inclusion as a mental disorder in diagnostic classification systems, and was listed in the ICD-11 version released for consideration by Member States ( http://www.who.int/classifications/icd/revision/timeline/en/ ). More research is needed into disorder definitions, validation of clinical tools, prevalence, clinical parameters, brain-based biology, socio-health-economic impact, and empirically validated intervention and policy ap- proaches. Potential cultural differences in the magnitudes and natures of types and patterns of PUI need to be better understood, to inform optimal health policy and service development. To this end, the EU under Horizon 2020 has launched a new four-year European Cooperation in Science and Technology (COST) Action Programme (CA 16207), bringing together scientists and clinicians from across the fields of impulsive, compulsive, and addictive disorders, to advance networked interdisciplinary research into PUI across Europe and beyond, ultimately seeking to inform regulatory policies and clinical practice. This paper describes nine critical and achievable research priorities identified by the Network, needed in order to advance understanding of PUI, with a view towards identifying vulnerable individuals for early intervention. The network shall enable collaborative research networks, shared multinational databases, multicentre studies and joint publications .
