Materialism, Financial Motives and Gambling: Examination of an Unexplored Relationship.

Gambling has an inherent structural monetary component, and financial motive is one of the main motivations for gambling. Despite this, and contrary to other addictive behaviours that involve money such as compulsive buying, gambling has never been studied from a materialism perspective. The objective of the present study was to explore the links between materialism and gambling disorder (GD) and whether this relationship is mediated by financial motives for gambling. We compared 65 pathological gamblers (PGs) seeking treatment to 65 matched non-problem gamblers. The data collection included socio-demographics, gambling characteristics, the Materialism Values Scale, the Gambling Motives Questionnaire-Financial, and the Rosenberg Self-Esteem Scale. The statistical analysis included linear mixed models and Structural Equation Modelling. The level of materialism was significantly higher for the PGs, except for the Centrality dimension. Only one mediated effect was significant, and it concerned an indirect path from Happiness through financial motives. Moreover, Happiness explained most of the variance of the probability of becoming a PG. Contrary to compulsive buying, the PGs seemed to display materialism in a more experiential way that was centred on what possessions can induce secondarily rather than on the possessions themselves. The belief that material possessions are essential to achieving happiness may encourage the PG to gamble, thus contributing to both the development and maintenance of GD. We provided evidence that materialism is a key concept in the comprehension of GD and should be further considered when adapting care strategies.

Effectiveness of At-Risk Gamblers' Temporary Self-Exclusion from Internet Gambling Sites.

To prevent risks associated with online gambling, many jurisdictions propose self-exclusion strategies as a part of a responsible gambling policy. To protect online gamblers, French law provides for a 7-day temporary non-reducible and voluntary self-exclusion measure that applies only to select websites. The objective of our study was to evaluate the effectiveness of this self-exclusion measure for at-risk online gamblers. It was an experimental randomized controlled trial targeted at risk prevention. The main outcomes were the money wagered and time spent gambling assessed 15 days (short-term) and 2 months (medium-term) after the implementation of the self-exclusion measure. The effectiveness of self-exclusion was also compared according to the gambling type (pure chance games, such as lottery or scratch tickets, skill and chance bank games such as sports betting or horserace betting, and skill and chance games such as poker). Sixty participants were randomly assigned to the experimental condition (n = 30; with the implementation of a self-exclusion measure) or control condition (n = 30). The randomization was stratified according to their favorite game [pure chance games (n = 20), skill and chance bank games (n = 20), and skill and chance social games (n = 20)]. The results revealed that self-exclusion had no short-term impact-but did have a medium-term impact-on gambling habits. After 2 months, the gambling-related cognitions ("illusion of control" and "the perceived inability to stop gambling") and the subscale "desire" of the Gambling Craving Scale (GACS) have decreased. Participants' opinions about the impact and effectiveness of self-exclusion were discussed. To conclude, it appeared that temporary self-exclusion is an interesting tool to protect online gamblers from excessive practices, but several modifications have to be made to improve its effectiveness and use.

Inhibitory control in poker: Do experienced non-pathological poker gamblers exhibit better performance than healthy controls on motor, verbal and emotional expression inhibition?

BACKGROUND AND AIMS: Strategic games, such as poker, require gamblers to develop several skills to perform better than others and to expect a potential gain. Players must remain as unpredictable and unreadable as possible by inhibiting the expression of their emotions in response to both good and bad poker events. The aim of the present study was to compare several aspects of the inhibition process in experienced poker gamblers and controls to better understand how inhibitory control is involved in poker performance. METHODS: Thirty experienced non-pathological poker gamblers (EG) and thirty healthy controls with no or limited poker experience (HC) completed 3 cognitive tasks. Each task measured a specific type of inhibition: motor inhibition [Go/No-Go task], verbal inhibition [Hayling Sentence Completion Task] and expressive inhibition [expressive suppression task, which combines subjective, expressive (facial EMG) and physiological (skin conductance, heart interbeat interval, cardiovascular and respiratory activation) measures of emotional experience]. Linear mixed models with random effects were performed. RESULTS: Inhibitory control skills were similar between the two groups, regardless of the form of inhibition tested. The only difference observed in EG was a higher ability to partially suppress the physiological expression of emotion. However, this difference was only present for negative and positive emotional induction and was not maintained for emotional induction related to poker situations. DISCUSSION AND CONCLUSIONS: The development of specific inhibition skills in experienced poker gamblers was not supported and raises questions about the transferability of poker skills previously discussed in the literature.
