Background and Aims: Electronic gaming machines (EGMs) are a significant source of gambling spend due to their widespread use. Skill-based gambling machines (SGMs) represent an innovative adaptation, merging EGMs' chance-based rewards with video game-like skills. This study aimed to explore the appeal and behavioural consequences of playing SGMs in comparison to traditional reel-based EGMs, particularly focusing on illusions of control, betting behaviour, and the subjective experience of gamblers., Methods: Participants (N = 1,260) were recruited online and engaged in an online task simulating either an SGM or a reel-based EGM, with outcomes represented to influence their survey compensation. The study examined the effect of SGMs relative to EGMs on bet size, persistence, enjoyment, illusions of control, game immersion, and the influence of demographic and gambling problem severity., Results: SGMs particularly appealed to younger adults, regular EGM players, and people with more gambling problems. Despite identical payout structures, people assigned to play SGM showed greater illusions of control, believing in the influence of skill on game outcomes and that practice could improve results. However, there was no significant difference in overall betting intensity between SGM and EGM players, although specific demographic groups showed faster betting speeds in SGMs., Discussion and Conclusions: SGMs, despite not inherently encouraging higher betting intensity, attract vulnerable groups and create illusions of control, posing new regulatory challenges. The visual and interactive features of SGMs, while appealing, might contribute to these perceptions, indicating a need for careful regulation and further research on their long-term impacts on gambling behaviour and harm.

New gambling products have been developed over time as technology permits. For example, early mechanical slot machines were later replaced by electronic gaming machines (EGMs), which enabled a faster speed of play and more immersive experience. EGMs have in the decades since their invention become one of the main drivers of gambling expenditure worldwide and are one of the gambling products most strongly associated with harm. This literature review considers research relevant to a new subcategory of EGM, 'skill-based' EGMs, termed 'SGMs' here. SGMs can be highly varied in content, with some representing a minimal departure from EGMs, where the typical bonus round is replaced by some skill-based activity, such as a simple video game, which could increase the machine's appeal. Other SGMs feature more radical departures from conventional EGMs, such as multiplayer games using intellectual property from popular TV shows or video games. These skill-based elements could tap into common gambling fallacies such as the illusion of control, and therefore facilitate harmful engagement. SGMs could also be less harmful than current EGMs, if skill-based elements break the dissociative states associated with EGM gambling. The intellectual property used in SGMs may increase their appeal among people who generally do not gamble, and the skill-based elements could increase their interest among gamblers who predominately prefer skill-based gambling formats such as sports betting. The novelty and varied content of SGMs present many open questions, which research should aim to address in future., (© 2024. The Author(s).)

Aims: Understanding how gambling harm is distributed is essential to inform effective harm reduction measures. This first national Australian study of gambling harm-to-self examined the extent, distribution, risk factors, and health related quality of life (HRQoL) impacts of this harm., Methods: A Random Digit Dialling sample of 15,000 Australian adults was weighted to key population variables. Key measures included the Gambling Harms Scale-10 (GHS-10), PGSI, SF-6D, gambling behaviours, and demographics. Analyses included ordinal logistic regression., Results: Amongst gamblers, 14.7% reported harm on the GHS-10, including 1.9% reporting high-level harm. While high-level harm occurred mainly in the problem gambling group (77.3%), other PGSI groups accounted for most of the more prevalent low (98.5%) and moderate (87.2%) harms reported. Proximal predictors of greater harm were use of online gambling and more frequent gambling on electronic gaming machines (EGMs), race betting sports betting, poker, skin gambling, scratchies, and loot box purchasing. Distal predictors were being younger, male, single, Aboriginal or Torres Strait Islander, and speaking a non-English language at home. At the population level, the greatest aggregate HRQoL impacts were amongst lower-risk gamblers, confirming the results of other studies regarding the 'prevention paradox'., Conclusions: The distribution of harm across gambler risk groups indicates the need for preventive measures, not just interventions for problem gambling. Reducing harm requires modifying product features that amplify their risk, especially for EGMs, race betting and sports betting that are both inherently risky and widely used. Gambling harm exacerbates health disparities for disadvantaged and vulnerable groups, requiring targeted resources and support.

Background: Gambling abstinence when underage lowers the risk of harmful gambling in later life. However, little research has examined why many young people refrain from gambling, even though this knowledge can inform protective strategies and lower risk factors to reduce underage gambling and subsequent harm. This study draws on the lived experience of adolescent non-gamblers to explore how social determinants while growing up have shaped their reasons and choices to not gamble., Methods: Fourteen Australian non-gamblers, aged 12-17 years, participated in an in-depth individual interview (4 girls, 3 boys) or online community (4 girls, 3 boys). Questions in each condition differed, but both explored participants' gambling-related experiences while growing up, including exposure, attitudes and behaviours of parents and peers, advertising, simulated gambling and motivations for not gambling. The analysis used adaptive grounded theory methods., Results: The grounded theory model identifies several reasons for not gambling, including not being interested, being below the legal gambling age, discouragement from parent and peers, concern about gambling addiction and harm, not wanting to risk money on a low chance of winning, and moral objections. These reasons were underpinned by several social determinants, including individual, parental, peer and environmental factors that can interact to deter young people from underage gambling. Key protective factors were parental role modelling and guidance, friendship groups who avoided gambling, critical thinking, rational gambling beliefs, financial literacy and having other hobbies and interests., Conclusions: Choices to not gamble emanated from multiple layers of influence, implying that multi-layered interventions, aligned with a public health response, are needed to deter underage gambling. At the environmental level, better age-gating for monetary and simulated gambling, countering cultural pressures, and less exposure to promotional gambling messages, may assist young people to resist these influences. Interventions that support parents to provide appropriate role modelling and guidance for their children are also important. Youth education could include cautionary tales from people with lived experience of gambling harm, and education to increase young people's financial literacy, ability to recognise marketing tactics, awareness of the risks and harms of gambling, and how to resist peer and other normalising gambling influences., (© 2024.

Background and Aims: COVID-19 lockdowns limited access to gambling but simultaneously elevated psychosocial stressors. This study assessed the relative effects of these changes on gambling risk status during and after the Australian COVID-19 lockdown from late-March to late-May 2020., Methods: The study administered three surveys to people who had gambled within the past year at T1. Wave 1 asked about before (T1, N = 2,125) and during lockdown (T2, N = 2,125). Subsequent surveys focused on one year (T3; N = 649) and two years after lockdown (T4, N = 458). The dependent variable was changes in reporting any problem gambling symptoms (PGSI 0 vs 1+). Bivariate analyses and multinomial logistic regression tested for significant associations with: demographics, psychosocial stressors (perceived stress, psychological distress, loneliness, health anxiety about COVID, financial hardship, stressful life events), gambling participation and gambling frequency., Results: Gambling participation and at-risk gambling decreased between T1 and T2, increased at T3, with little further change at T4. When gambling availability was curtailed, decreased gambling frequency on EGMs, casino games, sports betting or race betting, and lower psychosocial stress, were associated with transitions from at-risk to non-problem gambling. When gambling availability resumed, increased EGM gambling frequency, decreased online gambling frequency, and higher psychosocial stress were associated with transitions from non-problem to at-risk gambling., Discussion and Conclusions: Gambling availability appears a stronger influence on gambling problems, at the population level, than psychosocial risk factors. Reducing the supply of high-risk gambling products, particularly EGMs, is likely to reduce gambling harm.

Background and Aims: Smartphone, computer and land-based betting platforms each have distinctive features. This study examined 1) preferred features of sports betting platforms amongst young adults and 2) whether feature preferences vary with gambling severity., Methods: The study surveyed 616 Australians aged 18-29 years who bet at-least monthly on sports, esports and/or daily fantasy sports. Participants provided a simple rating of the importance of 24 features of betting platforms and then completed a discrete choice experiment to indicate their preferences amongst different groups of features., Results: Smartphones were the only platform providing all preferred features. The most important feature was ability to bet instantly 24/7 from any location, followed by electronic financial transactions. Less important features were ability to access betting information online and to bet with multiple operators. Social and privacy features, and access to promotions, did not significantly predict platform choice. The experiment found no significant differences in preferred features by gambling severity group or by gender. The non-experimental descriptive data, however, indicated that participants in the moderate risk/problem gambling categories placed significantly more importance on privacy, ability to place in-play bets, bet with cash, bet with a credit card, see frequent promotions, and bet with multiple operators., Discussion and Conclusions: Most features that bettors prefer can intensify betting. Curtailment of betting promotions, in-play betting, and credit card betting are measures that can assist higher-risk gamblers without unduly affecting other gamblers. Consumer protection tools, including mandatory pre-commitment, need strengthening to help counter the unique risks of smartphone betting.

Introduction: Understanding how patterns of drinking are associated with risky gambling in Australia is needed to inform an effective approach to minimise harm., Methods: This cross-sectional questionnaire study reports on 2,704 subsampled participants who completed survey questions about their patterns of drinking. With logistic regressions, we examined whether frequency of heavy episodic drinking (HED) and alcohol use while gambling were associated with risky gambling while controlling for sociodemographic variables., Results: Occasional HED and monthly HED were associated with any gambling (versus no gambling), but frequent HED was not significantly associated with gambling. The opposite pattern was found when predicting risky gambling. Occasional HED (i.e. less than monthly) was not significantly associated, but a higher frequency of HED (at least weekly) was associated with a higher likelihood of risky gambling. Drinking alcohol while gambling was associated with risky gambling, over and above HED. The combination of HED and use of alcohol while gambling appeared to significantly increase the likelihood of risky gambling., Conclusions: The association of HED and alcohol use while gambling with risky gambling highlights the importance of preventing heavy alcohol use among gamblers. The links between these forms of drinking and risky gambling further suggests that individuals who engage in both activities are specifically prone to gambling harm. Policies should therefore discourage alcohol use while gambling for example by prohibiting serving alcohol at reduced prices or to gamblers who show signs of being affected by alcohol and informing individuals of the risks associated with alcohol use while gambling., (© 2023.

Background and Aims: Simulated gambling products, like loot boxes and social casino games, contain gambling elements, but are not classified as gambling. They are available to minors, raising concerns about a "gateway effect" into gambling. This study examined the time course of young people's engagement in simulated and monetary gambling, and associations between simulated gambling and gambling problems and harm. A necessary, although not sufficient, condition for simulated games leading to real money gambling is that simulated play must come first., Method: Participants were 1,026 young adults (aged 18-25 years) who played video games in the last year. They reported the age at which they first took part in seven simulated and twelve monetary gambling products, and current gambling problems and harm., Results: First use of loot boxes and video games with gambling content tended to precede monetary gambling. Forms where gambling is a core gameplay element, such as social casino and demonstration games, tended to follow some monetary gambling forms. Engagement in most simulated gambling products was associated with greater harm from monetary gambling., Discussion: The findings leave open the possibility of a catalyst pathway from youth engagement in loot boxes and games with gambling content to later monetary gambling, but causal psychosocial mechanisms remain unclear. However, a pathway from social casino and demonstration games to monetary gambling appears less likely, which may instead reflect containment or substitution effects. Simulated gambling disproportionately attracts youth who are vulnerable to gambling problems and harm, indicating the need for consumer protection measures.

Background and Aims: Smartphones extend the situational characteristics of sports betting beyond those available with land-based and computer platforms. This study examined 1) the role of situational features and betting platforms in harmful betting behaviours and short-term betting harm, and 2) whether people with more gambling problems have preferred situational features, engage more in harmful betting behaviours, and experience more severe short-term betting harm., Methods: An ecological momentary assessment analysed 1,378 betting sessions on sports, esports or daily fantasy sports, reported by 267 respondents (18-29 years; 50.9% male) over 10 weeks., Results: Factor analysis revealed five situational features of betting sessions: 1) quick, easy access from home, 2) ability to bet anywhere anytime, 3) privacy while betting, 4) greater access to promotions and betting options, and 5) ability to use electronic financial transactions. Regression models underpinned the analyses. Greater short-term betting harm was significantly associated with the ability to bet anywhere anytime, privacy when betting, and greater access to promotions and betting options. Betting sessions when these features were prioritised were more likely to involve impulsive betting, use of betting inducements, and betting with more operators. Respondents with more gambling problems were more likely to prioritise privacy and the ability to bet anywhere anytime; and to bet on in-game events, use promotional inducements, bet with more operators, and report greater betting harm., Discussion and Conclusions: Certain situational features of sports betting are empirically associated with engagement and subsequent harm. Only smartphone betting combines all three features associated with betting harm.

Effective gambling messages should curb time and money spent on gambling, since these are the behaviours proximal to gambling-related harm. Studies that aim to find what messages best achieve these objectives are scarce, and most focus on electronic gaming machine (EGM) gambling rather than sports and race betting. The present study aimed to gather longitudinal evidence on previously identified messaging strategies. In an experiment, two types of messages, positive-emotional and norm-based, were contrasted against a control condition with generic messages (e.g., gamble responsibly). By stratified random assignment, participants (N = 2,074, 36% female), were exposed to 3 unique messages in each of 3 weeks, exclusive of pre- and post-surveys in weeks 1 and 5, respectively. There were no significant differences by condition in amounts-bet commercially on sports or race betting, time spent gambling, gambling-harm experienced, gambling-urges nor risk-related gambling beliefs. However, there was a significant decrease in all these outcomes over weeks 1 through 5. The messages may not have been the factor that contributed to the decrease in outcomes over time, as participating in the study may have also prompted self-reflection on gambling expenditure. Positive-emotional messages were rated most helpful and easily understood, and the highest-rated message was the control message, "only bet what you can afford." Despite no differences found between the conditions, the present study provided evidence that self-reflection on gambling expenditure is well-rated by gamblers as being helpful. Future experiments should be conducted to gauge the robustness of this finding., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Background: Electronic gaming machines (EGMs) are one of the most harmful forms of gambling at an individual level. It is unclear whether restriction of EGM functions and accessibility results in meaningful reductions in population-level gambling harm., Methods: A natural policy experiment using a large (N = 15,000) national dataset weighted to standard population variables was employed to compare estimates of gambling problems between Australian residents in Western Australia (WA), where EGMs are restricted to one venue and have different structural features, to residents in other Australian jurisdictions where EGMs are widely accessible in casinos, hotels and clubs. Accessibility of other gambling forms is similar across jurisdictions., Results: Gambling participation was higher in WA, but EGM participation was approximately half that of the rest of Australia. Aggregate gambling problems and harm were about one-third lower in WA, and self-reported attribution of harm from EGMs by gamblers and affected others was 2.7× and 4× lower, respectively. Mediation analyses found that less frequent EGM use in WA accounted for the vast majority of the discrepancy in gambling problems (indirect path = -0.055, 95% CI -0.071; -0.038). Moderation analyses found that EGMs are the form most strongly associated with problems, and the strength of this relationship did not differ significantly across jurisdictions., Discussion: Lower harm from gambling in WA is attributable to restricted accessibility of EGMs, rather than different structural features. There appears to be little transfer of problems to other gambling forms. These results suggest that restricting the accessibility of EGMs substantially reduces gambling harm.

Background and Aims: Concerned significant others (CSOs) can experience gambling-related harm, impacting their health and wellbeing. However, this harm varies depending on the type and closeness of the relationship with the person who gambles. We sought to determine the type and closeness of relationships that are more likely to experience harm from another person's gambling, and examine which aspects of health and wellbeing are related to this harm., Methods: We examined survey data from 1,131 Australian adults who identified as being close to someone experiencing a gambling problem. The survey included information on relationship closeness, gambling-related harm (GHS-20-AO), and a broad range of health and wellbeing measures; including the Personal Wellbeing Index (PWI), the 12-item Short Form Survey (SF-12), and the Positive and Negative Affect Schedule Short Form (PANAS-SF)., Results: CSOs in relationships where finances and responsibilities are shared were more likely to be harmed by another person's gambling problem, particularly partners (current and ex) and family members. This harm was most strongly associated with high levels of distress and negative emotions, impacting the CSO's ability to function properly at work or perform other responsibilities., Discussion and Conclusions: Support and treatment services for CSOs should consider addressing the psychological distress and negative emotions commonly experienced by CSOs.

Safer gambling messages are one potential input to a public health approach toward reducing gambling-related harm, and yet there is no strong evidence supporting current messages such as "gamble responsibly" or "keep the fun in the game". Furthermore, sports betting is increasing in popularity in multiple jurisdictions, such as Australia and the US, increasing the need to design effective messaging campaigns for race and sports betting. Compared to other gambling formats, such as electronic gambling machines, the level of potential skill involved in race and sports betting may raise unique issues regarding the design of effective messages. This review first highlights research from the related public health domains of alcohol and tobacco. Then, five potential areas for further messaging-based research in race and sports betting are discussed: teaching safer gambling practices, correcting gambling misperceptions, boosting conscious decision making, norm-based messages, and emotional messages. A broad approach to message design is encouraged, given the potential for individual differences in message receptivity, and for frequently-repeated messages to be ignored or cause negative psychological reactance., (© 2023.

This study aimed to examine gambling motivations for esports betting and skin gambling and their association with gambling frequency, problems, and harm. Data were collected via a cross-sectional online survey with 736 participants aged 18 + who engaged in esports cash betting (n = 567), esports skin betting (n = 180), or skin gambling on games of chance (n = 325). Respondents were asked to rate their motivations for the three activities across seven domains: social, financial, positive feelings or enhancement, internal regulation, skill building, competition/challenge, and skin acquisition. The results highlight both similarities and differences in gambling motivations across products. Financial gain and enhancement (i.e., excitement) were the main motivations endorsed for all activities, whereas skin acquisition was an additional motivation for esports skin betting and skin gambling. Across all three products, gambling to escape or improve mood was associated with higher levels of problem gambling and harm. Financial gain motivation was associated with problem gambling only for esports skin betting and skin gambling on games of chance. These findings underscore the importance of considering motivational influences on engagement with emerging gambling activities, especially since some motivations may be a contributing factor in harmful gambling outcomes., (© 2022.

Social casino games have achieved widespread popularity, and are accessed by more than 85 million people each day. Yet, why people play social casino games is largely unknown. To address this gap, an inductive approach was taken to better understand the motives for playing social casino games, as well as the motives for transitioning from social casino gaming to gambling and vice versa. To this end, 269 social casino gamers were asked to provide a ranked list of their motives for playing social casino games. Additionally, we asked participants their motivations for transitioning from gambling to social casino gaming (n = 202) or vice versa (n = 67). A total of 795, 605, and 201 unique responses describing motives for playing social casino games, transitioning from social casino gaming to gambling, and transitioning from gambling to social casino gaming, respectively, were analyzed using a thematic content analysis. The most frequently endorsed motive for playing social casino games was for enhancement (e.g., fun, challenge). Participants also noted playing to earn rewards, including money, and for social reasons. Several motives linked social casino game play to gambling. These included: to hone gambling-related 'skills', a desire to transition to gambling to win real money, and as a gambling harm-reduction strategy. Motives for playing social casino games did not differ significantly between those who first gambled and then transitioned to social casino gaming and vice versa, suggesting that once people begin playing social casino games, they have similar motives for continued engagement. The present study contributes to understanding the immense popularity of social casino games and their links to gambling., (© 2022.

Esports betting and skin gambling involve betting on the outcomes of video game competitions and/or using virtual currencies for betting. The present study evaluated a conceptual model linking video game involvement, video-game related gambling, traditional gambling, and gambling problems and harm. Data were collected via a cross-sectional online survey with 737 participants aged 18 + who engaged in esports cash betting (n = 576), esports skin betting (n = 184), or skin gambling on games of chance (n = 330). The findings highlighted the distinctly different relationships esports cash betting versus skin gambling had with traditional gambling involvement and harmful gambling. Gambling with skins on games of chance was predictive of gambling problems and gambling harm after controlling for participation in traditional gambling (OR = 1.32 and 1.17 respectively). Whereas betting on esports with cash was associated with betting on a variety of other forms of gambling, and there was no unique contribution to problems and harm over and above participation on these other forms (e.g., EGMs, sports betting). Skin gambling is directly implicated in gambling problems and harm, whereas cash betting on esports is only indicative of interest in many forms of potentially harmful gambling. Greater research attention to skin gambling is warranted, and particularly with respect to its role as a virtual currency more easily accessible for gambling., (© 2022. The Author(s).)

Gambling harms can impact the health and wellbeing of both individuals who gamble and those close to them. While harms occur across a spectrum of gambling risk levels, most research is conducted on people close to those gamblers who have severe problems. This study examined the health and wellbeing of people living with gamblers across the entire spectrum of gambling risk levels, via secondary analysis of the nationally-representative Household Income and Labour Dynamics in Australia Survey (HILDA). The subsample of interest comprised 13,698 respondents without a gambling problem of their own, aged between 15 and 84, and who lived in households where all residents completed the Problem Gambling Severity Index (PGSI). Health and wellbeing were measured via the SF-6D, the SF-36, and subjective wellbeing measures. Compared to those living in non-problem gambling households, participants living in problem-gambling households reported significantly lower mean SF-6D scores, lower scores on the SF-36 mental health domain, and significantly less satisfaction with both their financial situation and with feeling part of their local community. Participants living in moderate-risk gambling households also reported less satisfaction with their financial situation than those in non-problem gambling households. Conclusions: The results indicate that measurable impacts to the health and wellbeing of those living with gamblers occur predominantly at the more severe end of the risk level spectrum, except for financial dissatisfaction, which is also evident in those residing with gamblers categorised as moderate-risk., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

Research reports positive associations between gaming disorder (GD) in adolescents and loot box purchasing but has not examined this relationship for other types of simulated gambling. This study examined whether greater engagement and expenditure in three types of simulated gambling were associated with meeting the criteria for GD in adolescents. A sample of Australians aged 12-17 years (N = 826) was recruited through an online panel aggregator. It included 646 gamers (57.7% male) with 89 being classified as having past-year GD, as defined and measured by the Internet Gaming Disorder Scale. Independent variables comprised past-month engagement in three simulated gambling activities (games with 'mini' gambling components, social casino games, and loot boxes), loot box purchasing, other microtransactions, impulsiveness, and demographics. Logistic regressions first examined whether engagement in each of the three simulated gambling activities was individually associated with GD, then with all three in the same model, and then controlling for demographic variables and impulsivity. Logistic regressions also examined whether microtransactions and purchasing loot boxes were individually associated with GD, then with both in the same model, and then controlling for demographic variables and impulsivity. Adolescents who had engaged in each simulated gambling activity in the past month were more likely to report meeting the criteria for GD. These relationships remained significant when controlling for common demographics and impulsiveness. Past-month engagement in social casino games increased the odds of GD 2.5 times (95% CI: 1.54; 4.02), 2.4 times for games with 'mini' gambling components (95% CI: 1.42; 3.90) and 2.0 times for engaging in loot boxes (95% CI: 1.22; 3.21), but only social casino games remained significant when controlling for engagement in all three activities. The likelihood of meeting the criteria for GD increased 3.8 times with expenditure on microtransactions (95% CI: 2.32; 6.27) and 4.6 times for buying loot boxes, and each remained significant when both were included in the model. Compared to digital games without simulated gambling elements, simulated gambling appears to attract adolescents who report GD. Implications of the results are discussed in detail., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

In cross-sectional gambling studies, friends, family, and others close to those experiencing gambling problems (concerned significant others 'CSOs') tend to report detriments to their quality of life. To date, however, there have been no large, population-based longitudinal studies examining the health and wellbeing of CSOs. We analyse longitudinal data from the Household, Income and Labour Dynamics in Australia (HILDA) survey to examine the 18-year trajectories of general, social, health and financial wellbeing of household CSOs (n = 477) and compare these to those without a gambling problem in the household (n = 13,661). CSOs reported significantly worse long-term wellbeing than non-CSOs in their satisfaction with life, number of life stressors, and social, health and financial wellbeing. However, both social and financial wellbeing showed a temporal effect, declining significantly for CSOs at times closer to the exposure to the gambling problem. This finding suggests a causal link between living in a household with a person with a gambling problem and decreased CSO social and financial wellbeing. Policy responses, such as additional social and financial support, could be considered to assist CSOs impacted by another person's gambling problem., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Tulloch et al.

Do stressful life events cause gambling problems, or do gambling problems cause stressful life events? This study used a retrospective design to examine the temporal order of these associations. Specifically, the study employed a life course calendar in a self-directed online survey to minimise memory biases common in retrospective designs. A total of 1564 US respondents who had gambled at any point in their life (51.0% female, median age 46) were asked whether, for each year of their adult life, they had experienced each of eight stressful life events, and whether they had engaged in casual or heavy gambling, drinking or drug use, with heavy gambling defined in line with a problem gambling definition. We found that five stressful life events were associated with the onset of heavy gambling: work issues, financial issues, legal issues, relationship issues and the death of a loved one. The same five stressful life events predict the cessation of an episode of heavy gambling, indicating a possible tendency for gambling problems to self-resolve in the presence of stress. Insights are also gained into comorbidities with alcohol and drug use, and the course of stressful life events and gambling and substance use throughout the life course, albeit with a non-representative sample. The methodology allows tentative conclusions in terms of possible causation pathways, indicating that stressful life events may play a role both in the onset and the maintenance (or cessation) of gambling problems., (© 2021.

Background and Aims: Legacy gambling harms are negative consequences of gambling that extend past periods of low risk, moderate risk and problem gambling. Gambling harm is typically measured within a 12-month timeframe and is often restricted to examining harm amongst active gamblers. The present research aimed to explore whether people experienced gambling harms 12 months or more after the resolution of at-risk or problem gambling, and how long these legacy harms lasted., Methods: An online survey was conducted in New Zealand with past and current gamblers and concerned significant others (CSOs) of gamblers, N = 1,240 (50.8% female), that asked them about both past and current gambling harms., Results: A majority of both gamblers and CSOs of gamblers indicated that they still suffered from gambling harm even after most of their behavioural issues with gambling had been resolved, 12+ months ago. Legacy gambling harms reduced over time, with harms diminishing most quickly in the early years, and having an average half-life of 4 years. Harms involving community-relationships, church involvement, and domestic and other violence resolved more quickly than others., Discussion and Conclusions: Legacy harms are common among ex-problem gamblers and should be considered in any full accounting of the impacts of gambling., Conclusion: Understanding the time course and persistence of legacy harms from gambling can provide gamblers, treatment professionals and public health experts with insights into how to address gambling's long-term consequences.

Simulated gambling, such as playing a virtual slot machine for points rather than money, is increasingly part of the online gaming experience for youth. This study aimed to examine (1) if youth participation in simulated gambling games is associated with participation in monetary gambling; (2) if youth participation in simulated gambling games is associated with increased risk of problematic gambling when controlling for breadth of monetary gambling (i.e., number of gambling forms); and (3) if monetary expenditure and time spent playing simulated gambling games increase the risk of problematic gambling. Two samples of Australians aged 12-17 years were recruited-826 respondents through an online panel aggregator (mean age 14.1 years) and 843 respondents through advertising (mean age 14.6 years). Aim 1 was addressed using chi-square and correlation analyses. Linear multiple regression analyses were conducted to address Aims 2 and 3. The findings in both samples supported the study's hypotheses-that (1) youth who play simulated gambling games are more likely to participate in monetary gambling, and that (2) participation and (3) time and money expenditure on simulated gambling are positively and independently associated with risk of problematic gambling when controlling for the number of monetary gambling forms, impulsivity, age and gender. To better protect young people, simulated gambling should, at minimum, emulate the consumer protection measures required for online gambling.

Background: Over the last decade, the provision of online gambling has intensified with increased access, enhanced betting markets, a broader product range, and prolific marketing. However, little research has explored how this intensification is influencing contemporary gambling experiences. This study focused on two research questions: 1) What changes in online gambling have online gamblers observed over the past decade? 2) How have these changes influenced the online gambling experiences and behaviours reported by treatment-seeking and non-treatment-seeking gamblers?, Methods: Two samples of Australian adults were interviewed: 1) 19 people who had been gambling online for at least a decade and with no history of treatment-seeking for online gambling, and 2) 10 people who had recently sought professional help for an online gambling problem. Telephone interviews were semi-structured, with questions that encouraged participants to consider how their online gambling, including any harmful gambling, had been influenced by changes in operator practices and online gambling environments. Data were analysed using thematic analysis., Results: Both treatment- and non-treatment-seekers noted the increased speed and ease of online gambling, which now enables instant access from anywhere at any time and increased their gambling opportunities. Both groups highlighted the continued proliferation of advertising and inducements for online gambling, particularly during televised sports and racing events, in social media, and through targeted push marketing. Many treatment- and non-treatment-seekers were aware of the vast range of recently introduced bet types, particularly multi-bets. Treatment-seekers disproportionately reported negative effects from these changes, and described how and why they fostered their increased gambling, impulsive gambling, persistence and loss-chasing. They reported limited uptake and effectiveness of current harm minimisation tools., Conclusions: Counter to stated policy and practice objectives to minimise gambling harm, industry changes that have made online gambling easier, faster, and more heavily incentivised, and increased the array of complex bets with poorer odds, unduly affect addicted and harmed individuals - who are also the most profitable customers. Further consideration is needed to ensure gambling policy, industry practices and public health measures more effectively reduce gambling harm in contemporary settings. Inducements and the poor pricing of complex bets such as multi-bets, and their outsized attraction to players with problems, should be a key focus., (© 2022. The Author(s).)

Background and Aims: Gambling-related harm to concerned significant others (CSOs) is an important public health issue since it reduces CSOs' health and wellbeing in numerous life domains. This study aimed to 1) estimate the first national prevalence of CSOs harmed by gambling in Australia; 2) identify the characteristics of CSOs most at risk of harm from another person's gambling; 3) compare the types and number of harms experienced by CSOs based on their relationship to the person who gambles; and 4) compare the number of harms experienced by CSOs by self-identified gender., Methods: Based on a national CATI survey weighted to population norms, 11,560 respondents reported whether they had been personally and negatively affected by another person's gambling in the past 12 months; and if so, answered detailed questions about the harms experienced from the person's gambling who had harmed them the most., Results: Past-year prevalence of gambling-related harm to adult Australian CSOs was (6.0%; 95% CI 5.6%-6.5%). CSOs most commonly reported emotional harms, followed by relationship, financial, health and vocational harms, respectively. Former partners reported the most harm, followed by current partners, other family members and non-family members, respectively. Female CSOs were more likely to report more harm and being harmed by a partner or other family member, and male CSOs from a non-family member., Discussion and Conclusions: The findings provide new insights into the wider societal burden of gambling and inform measures aimed at reducing harm to CSOs from gambling and supporting them to seek help.

Adolescents can easily access esports betting sites and place bets using cash or skins. This descriptive cross-sectional study examined the characteristics of adolescent esports bettors and relationships between their esports betting, video gaming activities, monetary gambling participation, and at-risk/problem gambling. Two survey samples of Australians aged 12-17 years were recruited through advertisements (n = 841) and online panel providers (n = 826). In both samples, gender and parents' living situation did not differ by past-month esports cash and skin betting, but recent esports betting was associated with engaging in esports gaming activities such as playing and watching esports, and in monetary gambling activities. Past-month esports betting using cash and skins was significantly associated with at-risk/problem gambling. After controlling for recent monetary gambling, recent esports skin bettors were over 3 times more likely to meet criteria for at-risk/problem gambling. Esports betting using skins appears to pose risks for young people and is easily accessible through unlicensed operators., Competing Interests: The authors have declared that no competing interests exist.

Background and Aims: Purchasing loot boxes in digital games is akin to gambling as it involves risking money for a chance-based reward of uncertain value. Research has linked buying loot boxes to problem gambling amongst adolescents, but has not examined co-occurring gambling participation. This study examined links between loot box purchasing and problem gambling amongst adolescents while controlling for monetary gambling participation., Methods: Two survey samples of Australians aged 12-17 years were recruited through advertisements (n = 843) and online panels (n = 826). They included n = 421 and n = 128 adolescents, respectively, who met criteria for problem gambling., Results: Past-month loot box purchasing was significantly related to gambling problems in bivariate analyses. When including age, gender and past-month monetary gambling, loot box purchases were still associated with at-risk and problem gambling in both samples. As expected, these other predictors attenuated the predictive value of recent loot box purchases in relation to gambling problems. The odds-ratios, nevertheless, were still in the predicted direction and remained significant. When controlling for monetary gambling, age and gender, recent loot box purchasing increased the odds of problem gambling 3.7 to 6.0 times, and at-risk gambling 2.8 to 4.3 times., Discussion and Conclusions: While causal relationships between loot box purchasing and problem gambling remain unclear, the results indicate that loot boxes disproportionately attract adolescents experiencing gambling problems, adding to the financial stress already caused by gambling. Consumer protection measures, youth and parental education, and age restrictions on loot box games are needed to protect young people.

A number of studies have explored the relationship between religious beliefs and gambling (including gambling fallacies and gambling harm) but report seemingly contradictory findings. While some studies have found religious belief to be positively associated with gambling fallacies, others have found it to be a protective factor from gambling harms. One explanation for these differing effects is that gambling fallacies and metaphysical religious belief share properties of supernatural and magical thinking. Nevertheless, social support and moral strictures associated with religion might help protect against an unhealthy engagement with gambling. Using a multidimensional measure of religiosity, we hypothesised that only the supernatural facet of religious adherence would present a risk for gambling fallacies. We analysed two archival data sources collected in Canada (Quinte Longitudinal Study: N = 4121, M age  = 46, SD age  = 14, Female = 54%; Leisure, Lifestyle and Lifecycle Project: N = 1372, M age  = 37, SD age  = 17, Female = 56%). Using the Rohrbaugh-Jessor Religiosity Scale, we confirmed that the supernatural theistic domain of religion was a positive risk factor for gambling fallacies. However, participation in ritual (behavioural) aspects, such as churchgoing, was negatively associated with risk, and no effect was observed for the consequential (moral) domain. We conclude that multidimensional aspects in religious measures may account for conflicting prior findings., (© 2021.

Purpose: Harms due to excessive gambling can be experienced by gamblers and those close to them. Family gambling problems (FGPs) are currently under-researched, particularly in population-representative samples. This study aimed to identify prevalence, risk factors, and the complex of stressors and health-related consequences associated with FGPs, as well as isolating the impact of FGPs on physical and psychological health problems., Methods: We analysed data from the National Health Survey 2011-13, a large (N = 15,475) nationally representative sample of Australian adults. Participants reported on the presence of 14 family stressors (including FGPs), self-assessed health status, and risky health behaviours. Psychological impact was measured by the Kessler Psychological Distress Scale-10, as well as several indicators of the presence of mental health problems., Results: Overall, 1.7% of households reported a FGP. Interviewees in these households reported three times the number of other stressors than those without a FGP. In addition, they were around eight times more likely to be experiencing other addictions (drug and alcohol related problems) and stressors associated with socially deviant behaviours (trouble with police, abuse or violent crime, and witness to violence). Once age, gender, socioeconomic disadvantage, and other stressors were controlled for, FGPs significantly predicted lower self-assessed health and higher psychological distress., Conclusions: FGPs occur within a complex of other addictions and stressors, impacting the quality of life of people close to problem gambling. The findings are discussed in relation to their support for General Strain Theory (Agnew, Criminology 30:47-87, 1992)., (© 2020. Springer Science+Business Media, LLC, part of Springer Nature.)

Background: Studies have found an association between problem gambling and poverty. However, there is relatively little research on social inequalities and problem gambling using population representative data., Methods: A population-representative self-report web-based and postal survey with register-based linkage was conducted in the three geographical areas of Finland. Participants (n = 7186, aged 18 or older) were randomly selected from the population register. Sociodemographic factors and social welfare benefits were studied among gambling groups and their statistical difference were examined by χ2 test. Seven logistic regression models were calculated, where unemployment, social security benefits and low income were treated as dependent variables and where sex, age, family structure and education were controlled as covariates. The results were presented as odds ratios (OR) with 95% confidence intervals (CIs)., Results: Problem and at-risk gambling (ARG) was more common among people who were unemployed [PG: χ2=6.4 (1), P < 0.01, ARG: χ2=12.4 (1), P < 0.001] or had received social security benefits [PG: χ2=41.6 (1), P < 0.001, ARG: χ2=22.9 (1), P < 0.001]. The OR for problem gambling was high as 5.6 (CI: 3.22-9.61) among respondents who had received social assistance even when covariates were taking into count. Almost a third of those experiencing problem or at-risk gambling received at least one form of social security benefit., Conclusions: The most important task of gambling policy should be reducing gambling-related harms and diminishing social inequality. However, even in government organized system where gambling profits are used for common good, profits come from the most socially disadvantaged people thereby exacerbating inequality., (© The Author(s) 2021.

Background and Aims: Excessive time and money spent on gambling can result in harms, not only to people experiencing a gambling problem but also to their close family and friends ("concerned significant others"; CSOs). The current study aimed to explore whether, and to what extent, CSOs experience decrements to their wellbeing due to another person's gambling., Methods: We analysed data from The Household Income and Labour Dynamics in Australia Survey (HILDA; N = 19,064) and the Canadian Quinte Longitudinal Study (QLS; N = 3,904). Participants either self-identified as CSOs (QLS) or were identified by living in a household with a person classified in the problem gambling category by the PGSI (HILDA). Subjective well-being was measured using the Personal Wellbeing Index and single-item questions on happiness and satisfaction with life., Results: CSOs reported lower subjective wellbeing than non-CSOs across both countries and on all three wellbeing measures. CSO status remained a significant predictor of lower wellbeing after controlling for demographic and socio-economic factors, and own-gambling problems. There were no significant differences across various relationships to the gambler, by gender, or between household and non-household CSOs., Discussion and Conclusions: Gambling-related harms experienced by CSOs was reliably associated with a decrease in wellbeing. This decrement to CSO's wellbeing was not as strong as that experienced by the person with the first-order gambling problem. Nevertheless, wellbeing decrements to CSOs are not limited to those living with a person with gambling problems in the household and thus affect many people.

Background and Aims: Skin gambling uses in-game items (skins) acquired in video games, to gamble on esports, games of chance, other competitive events and privately with friends. This study examined characteristics of adolescent skin gamblers, their engagement in monetary gambling, and relationships between skin gambling and at risk/problem gambling., Methods: Two samples of Australian adolescents aged 12-17 years were recruited to an online survey through advertisements (n = 843) and an online panel provider (n = 826)., Results: In both samples, past-month skin gamblers (n = 466 advertisements sample; n = 185 online panel sample) were more likely to have lower wellbeing, score as having an internet gaming disorder on the IGD, engage in more types of monetary gambling, and meet criteria for problem gambling on the DSM-IV-MR-J. Past-month skin gambling uniquely predicted problem gambling when controlling for past-month gambling on 11 monetary forms and the total number of monetary gambling forms., Discussion and Conclusions: Underage participation in skin gambling is a growing concern. The strong convergence between engagement in skin gambling and monetary gambling suggests common risk factors may increase the propensity of some adolescents to gamble on these multiple forms. Nonetheless, past-month skin gambling predicted problem gambling even when controlling for past-month monetary gambling, indicating its unique contribution to gambling problems and harm. While the study was based on non-probability samples, its results strengthen the case for regulatory reforms, age restrictions and public health education to prevent underage skin gambling and its potentially harmful consequences for children and young people.

Background and Aims: It is common for gambling research to focus on problem and disordered gambling. Less is known about the prevalence of gambling-related harms among people in the general population. This study aimed to develop and validate the 18-item version of the Short Gambling Harms Screen (SGHS-18)., Methods: Population-representative web-based and postal surveys were conducted in the three geographical areas of Finland ( n = 7186, aged 18 or older). Reliability and internal structure of SGHS-18 was assessed using coefficient omega and via confirmatory factor analysis (CFA). Four measurement models of SGHS-18 were compared: one-factor, six-factor, a second-ordered factor model and a bifactor model (M4)., Results: The analysis revealed that only the bifactor model had adequate fit for SGHS-18 (CFI = 0.953, TLI = 0.930, GFI = 0.974, RMSEA = 0.047, SRMR = 0.027). The general factor explained most of the common variance compared to specific factors. Coefficient omega hierarchical value for global gambling harm factor (0.80) was high, which suggested that SGHS-18 assessed the combination of general harm constructs sufficiently. The correlation with the Problem and Pathological Gambling Measures (PPGM) was 0.44, potentially reflecting that gambling harms are closely-although not perfectly-aligned with the mental health issue of problem gambling. SGHS-18 scores were substantially higher for participants who gambled more often, who spent more money or who had gambling problems, demonstrating convergent validity for the screen., Discussion: The SGHS-18 comprehensively measures the domains of gambling harm, while demonstrating desirable properties of internal consistency, and criterion and convergent validity.

The objective of this experiment is to assess whether priming for contamination and purity causes a change in attitudes to health interventions, including vaccination, and complementary and alternative medicines (CAMs). An online priming experiment was conducted with four between-subject experimental conditions including photos of: 1) biological contamination, 2) chemical contamination, 3) pure environments, such as pristine landscapes, and 4) hazard signs/icons indicating physical threats. Two control conditions included photos of neutral scenes and neutral icons, whereby experimental groups were compared against the related control groups (photograph for conditions 1-3 and neutral icons for condition 4). Subjects were randomly assigned to one of the six conditions, and after exposure to the images they were asked to rate 10 conventional and alternative health interventions for effectiveness and safety, as well being assessed for disgust sensitivity using the reduced-item DPSS-R [10]. A total of 642 adults completed the experiment. Exposure to primes did not cause a differential change in ratings of health interventions. Nevertheless, higher levels of sensitivity to disgust were associated with lower ratings of the effectiveness of MMR vaccination, tetanus injection, antibiotics, and surgery; and higher levels of sensitivity to disgust were associated with higher ratings of effectiveness of vitamins/minerals. In conclusion, this online experiment did not find an experimental effect of priming for contamination and purity on subjects' ratings of the safety and effectiveness of conventional and alternative health interventions. This indicates that attitudes to these health interventions are not influenced by a temporary increase in the salience of feelings of contamination or purity. However, individual differences in disgust sensitivity are related to their attitudes to vaccination and CAM interventions., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Ltd.

Many video games incorporate gambling-like elements into their design (and vice versa). Social casino games - a type of video game that mimics gambling activities-are one such example. In the current experimental research, we examined whether offering tangible rewards (i.e., rewards with value outside the game) in a social casino game was associated with increased social casino game play and subsequent gambling. Participants (N = 213, M age  = 36.5, 55.3% female) were recruited from CloudResearch. They were randomly assigned to either a reward condition (n = 109) in which, following a week of social casino game play, participants could trade in their virtual credits for a bonus, or a control condition in which the possibility of reward was not presented (n = 104). Following the week of play, all participants were then provided with an opportunity to gamble in an online roulette game with their study compensation. Participants in the reward condition placed more bets and bet higher credit amounts in the social casino game than participants in the control condition. In contrast, no differences were found between the two groups regarding their decision to gamble with their remuneration. Participants who elected to gamble reported higher problem gambling severity and gambling-related cravings. There were no differences in impulsivity. These results suggest that offering tangible rewards in social casino games may increase social casino game play but not necessarily the decision to gamble with real-world money., (Copyright © 2021 Elsevier Ltd.

Jurisdictions around the world have a self-declared mandate to reduce gambling-related harm. However, historically, this concept has suffered from poor conceptualisation and operationalisation. However, recent years have seen swift advances in measuring gambling harm, based on the principle of it being a quantifiable decrement to the health and wellbeing of the gambler and those connected to them. This review takes stock of the background and recent developments in harm assessment and summarises recent research that has validated and applied the Short Gambling Harms Screen and related instruments. We recommend that future work builds upon the considerable psychometric evidence accumulated for the feasibility of direct elicitation of harmful consequences. We also advocate for grounding harms measures with respect to scalar changes to public health utility metrics. Such an approach will avoid misleading pseudo-clinical categorisations, provide accurate population-level summaries of where the burden of harm is carried, and serve to integrate gambling research with the broader field of public health.

Background and Aims: Problem gambling severity and gambling-related harm are closely coupled, but conceptually distinct, constructs. The primary aim was to compare low-risk gambling limits when gambling-related harm was defined using the negative consequence items of the Problem Gambling Severity Index (PGSI-Harm) and the Short Gambling Harms Scale items (SGHS-Harm). A secondary aim was compare low-risk limits derived using a definition of harm in which at least two harms across different domains (e.g. financial and relationship) were endorsed with a definition of harm in which at least two harms from any domain were endorsed., Methods: Data were collected from dual-frame computer-assisted telephone interviews of 5,000 respondents in the fourth Social and Economic Impact Study (SEIS) of Gambling in Tasmania. Receiver operating characteristic (ROC) curve analyse were conducted to identify low-risk gambling limits., Results: PGSI-Harm and SGHS-Harm definitions produced similar overall limits: 30-37 times per year; AUD$510-$544 per year; expenditure comprising no more than 10.2-10.3% of gross personal income; 400-454 minutes per year; and 2 types of gambling activities per year. Acceptable limits (AUC ≥0.70) were identified for horse/dog racing, keno, and sports/other betting using the PGSI definition; and electronic gaming machines, keno, and bingo using the SGHS definition. The requirement that gamblers endorse two or more harms across different domains had a relatively negligible effect., Discussion and Conclusions: Although replications using alternative measures of harm are required, previous PGSI-based limits appear to be robust thresholds that have considerable potential utility in the prevention of gambling-related harm.

Background and Aims: Loot boxes are a common feature in video games where players win, buy or are gifted a virtual box or other container that is unwrapped to reveal virtual items of value, such as skins, weapons, in-game currency or special abilities. The current study aimed to relate the use of loot boxes to gambling problems and harm., Methods: An online survey was conducted with 1,954 adolescents and young adults from NSW Australia, 59.9% female (aged 12-24), recruited by online panel aggregator, Qualtrics., Results: Buying and selling loot boxes was associated with higher 12-month gambling frequency and gambling problems in young adults, aged 18-24 (Problem Gambling Severity Index). Young adults who bought loot boxes additionally had more gambling-related harms (Short Gambling Harms Screen). Young women, aged 18-24, who opened, bought and/or sold loot boxes spent more money in the last 12 months on gambling. In adolescents, aged 12-17, buying loot boxes was similarly associated with gambling problems (DSM-IV-MR-J). Furthermore, adolescent girls who bought and/or sold loot boxes viewed gambling more positively than other girls (Attitudes Towards Gambling Scale). There was no evidence, however, that longer-term experience in opening or purchasing loot boxes, a differentiating feature of the survey, is associated with current gambling problems., Discussion and Conclusions: This study suggests that loot boxes may be attractive to people who are already predisposed to engage in other gambling, and females who use loot boxes may have unique vulnerabilities to gambling problems that could be explored in future research.

Assessing the harmful consequences of gambling is an area of active investigation. One measure intended to capture gambling-related harm is the 10-item short gambling harm screen (SGHS). Although good psychometric properties have been reported, it has been suggested that the screen's less severe probes may not represent genuinely harmful consequences, but rather may reflect rational opportunity costs. Consequently, it has been argued that the screen may lead to overestimation of the extent of gambling-related harm in the population. The current study sought to examine the psychometric performance of three less severe suspect items in the SGHS. Associations between each of these items and a specially constructed scale of relatively severe "unimpeachable" gambling harms were calculated from archival data from 5551 Australian and New Zealand gamblers. All three suspect items, both individually and upon aggregation, predicted greater endorsement of "unimpeachable" harms, and indicated the presence of gambling problems. Moreover, the SGHS as a whole is highly correlated with "unimpeachable" gambling harms. Including suspect items in the SGHS was found to improve predictions of low- and moderate-risk gambling status, but slightly decreased predictions of severe gambling problems. The results are inconsistent with the notion that SGHS harm probes capture either inconsequential consequences or opportunity costs. They confirm prior findings that harm symptomatology is unidimensional, and that the report of multiple more prevalent, but less severe, harms serves as an effective indicator of the spectrum of experienced harm.

Electronic gaming machines (EGMs) and other gambling-themed simulators are a popular sub-genre of video-games or "apps" played on mobile devices (King et al. in Comput Hum Behav 31(Supplement C):305-313, 2014). Qualitative evidence suggests that some people use gambling-themed simulators in an attempt to limit their real-money expenditure (Thorne et al. in J Gambl Issues 34:221-243, 2016), although playing such games might also encourage gambling due to anticipated enjoyment or profit. To test the potential relationship between use of simulated mobile gambling products and real-money gambling, a study was devised to explore current and retrospective accounts, as well as a prospective trial of how weekly play on EGM simulators might influence subsequent gambling. A total of 736 EGM gamblers (421 male) completed an initial scoping survey on their current and retrospective use of simulated and real-money gambling products. By invitation, 556 people (314 male) from the initial survey also volunteered in a 24 weeks follow-up study where approximately half (48.2%) were randomly assigned to play a simulated game, "Lucky Lolly Slots", for at least 5 min each week. Simulated gambling sessions were recorded for both Lucky Lolly Slots and any other gambling apps played by the participants. Results showed that people who had played gambling-themed EGM apps at some point in their lifetime had a higher frequency of play on real-money EGMs and were more likely to admit to current gambling problems. In addition, those people who played a simulated EGM app prior to age 13 nominated an earlier age at which they "gambled the most" in adolescence. In the 24 weeks trial, people's app play (number of sessions) in 1 week reliably predicted increases in real-money gambling the following week. We found no evidence that people who were trying to reduce their expenditure were contrarily influenced to gamble less as a result of their app play, with their app-sessions similarly being related to increases in expenditure. The present results suggest that gamblers who play simulated games are likely to be influenced to gamble more on real-money forms of gambling as a result of their use. The study raises particular concerns about the widespread availability and popularity of such gambling-themed simulators amongst children and adolescents.

Gambling problems are increasingly understood as a health-related condition, with harms from excessive time and money expenditure contributing to significant population morbidity. In many countries, the prevalence of gambling problems is known with some precision. However, the true severity of gambling problems in terms of their impact on health and wellbeing is the subject of ongoing debate. We firstly review recent research that has attempted to estimate harm from gambling, including studies that estimate disability weights using direct elicitation. Limitations of prior approaches are discussed, most notably potential inflation due to non-independent comorbidity with other substance use and mental health conditions, and potential biases in the subjective attribution of morbidity to gambling. An alternative indirect elicitation approach is outlined, and a conceptual framework for its application to gambling is provided. Significant risk factors for propensity to develop gambling problems are enumerated, and relative risks for comorbidities are calculated from recent meta-analyses and reviews. Indirect elicitation provides a promising alternative framework for assessing the causal link between gambling problems and morbidity. This approach requires implementation of propensity score matching to estimate the counterfactual, and demands high quality information of risk factors and comorbid conditions, in order to estimate the unique contribution of gambling problems. Gambling harm is best understood as a decrement to health utility. However, achieving consensus on the severity of gambling problems requires triangulation of results from multiple methodologies. Indirect elicitation with propensity score matching and accounting for comorbidities would provide an important step towards full integration of gambling within a public health paradigm.

Background and Aims: Harmful gambling has been associated with the endorsement of fallacious cognitions that promote excessive consumption. These types of beliefs stem from intuitively derived assumptions about gambling that are fostered by fast-thinking and a lack of objective, critical thought. The current paper details an experiment designed to test whether a four-week online intervention to strengthen contextual analytical thinking in gamblers is effective in changing gamblers cognitions and encouraging safer gambling consumption., Methods: Ninety-four regular gamblers who reported experiencing gambling-related harm were randomly allocated to either an experimental (n = 46) or control condition (n = 48), including 45 males, ranging from 19 to 65 years of age (M = 36.61; SD = 9.76). Following baseline measurement of gambling beliefs and prior week gambling consumption, participants in the experimental condition were required to complete an adaption of the Gamblers Fallacy Questionnaire designed to promote analytical thinking by educating participants on common judgement errors specific to gambling once a week for four weeks. Post-intervention measures of beliefs and gambling consumption were captured in week five., Results: The experimental condition reported significantly fewer erroneous cognitions, greater endorsement of protective cognitions, and reduced time spent gambling post-intervention compared to baseline. The control group also reported a reduction in cognitions relating to predicting and controlling gambling outcomes., Conclusion: Cognitive interventions that encourage gamblers to challenge gambling beliefs by reflecting on gambling involvement and promoting critical thinking may be an effective tool for reducing the time people invest in gambling activities.
