Mapping Youth Awareness of Sports Betting Advertising During the 2022 FIFA World Cup

Young people are known to be highly engaged in sports betting and therefore may be particularly susceptible to the effects of gambling-related advertising. The purpose of the present study was to examine young people’s recall of sports betting advertising during the 2022 FIFA World Cup. The sample consisted of 190 UK residents aged 18–24 who had watched at least one 2022 World Cup match. A cross-sectional survey was conducted to collect data on participants' recall of sports betting advertisements across several media types and for different bets and betting offers, as well as their problem gambling scores. The findings indicated that young people were able to recall a high amount of advertising for various types of bets (95.6%) and betting inducements (89.5%). A high proportion of young people recalled advertising for risky bet types and promotions, such as 64.2% for in-play betting and 68.1% for sign-up offers. Overall, higher-risk gamblers recalled encountering more advertising than lower-risk gamblers. Participants recalled encountering sports betting advertisements on social media the most (10–14 ads per week), then on internet banners and television (5–9 ads per week, respectively). Less than half (46.3%) of respondents were aware of advertising for responsible gambling tools. This study underscores the need for policy measures that limit young people's exposure to gambling advertising, particularly for products that may contribute to gambling-related harm, and that increase the promotion of responsible gambling tools.

This time with feeling: In-play sports betting as a vehicle for emotion regulation.

The purpose of this research was to assess factors (i.e., emotion regulation, impulsivity) that motivate in-play sports betting. Specifically, we examined whether individuals report increased excitement after placing an in-play bet and whether trait negative and positive urgency moderate the effect of emotion regulation motives on in-play betting frequency. Three cross-sectional studies were conducted, each following a major sporting event: Superbowl LVI (56) (Study 1), March Madness Final (Study 2), and Union of European Football Associations Champions League Final (Study 3). Participants were U.S. (NStudy 1 = 111; NStudy 2 = 121) and U.K. (NStudy 3 = 239) residents who reported placing at least one in-play bet during the respective sporting events. Participants completed self-report measures of excitement, emotion regulation motives, in-play betting frequency, problem gambling, and trait affective impulsivity. Data from the three studies were pooled to conduct an integrative data analysis (IDA). Participants reported increased excitement after placing an in-play bet (p < .001). In bivariate analyses, greater emotion regulation motives were associated with greater in-play betting frequency (p < .05). In moderation analyses, emotion regulation motives interacted with trait negative (p < .001) and positive urgency (p < .001) to predict in-play betting frequency, such that the bivariate effects were amplified among those higher (relative to lower) in trait affective impulsivity. In-play sports betting is an exciting activity that people who gamble may engage in to regulate their emotions. These effects are amplified in those with high trait affective impulsivity. Responsible gambling tools such as mandatory play breaks may discourage the continuation of impulsive betting episodes. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The Efficacy of Voluntary Self-Exclusions in Reducing Gambling Among a Real-World Sample of British Online Casino Players

Online gambling is a socially acceptable means of entertainment, but it can also have a negative impact on many areas of life and lead to problem gambling for a minority of individuals. In recent years, gambling operators have increasingly implemented responsible gambling tools to help at-risk gamblers control and limit their gambling. One such tool is voluntary self-exclusion (VSE), where gamblers can exclude themselves from the gambling platform for a self-selected period of time. Despite the widespread use of VSE, there are few published studies on the efficacy of VSE among online gamblers and none on whether (and what type of) gamblers return to gambling after self-exclusion and how VSE affects their wagering if they return. Using a secondary dataset, the present study empirically analyzed a real-world sample of 3,203 British online casino players who opted for a VSE between January 2021 and August 2022. Analysis showed that most players who took a short-term VSE (up to 38 days) started gambling again on the platform after their self-exclusion ended, while players who opted for long-term self-exclusion (more than 90 days) did not start gambling again on the platform. A return to the gambling platform after VSE was positively associated with (i) a shorter duration of the self-exclusion, (ii) being female, (iii) gambling on more days, (iv) placing more bets, (v) playing fewer type of games, and (vi) having a lower average number of deposits per day. Players who returned from VSE did not change their wagering compared to a matched control group. These results suggest that short-term VSE may not be as effective as long-term VSE in reducing gambling. Overall, the present findings suggest that gamblers returning from VSE should be closely monitored, especially if the reason for self-exclusion is related to problem gambling.

Using machine learning to retrospectively predict self-reported gambling problems in Quebec.

Participating in online gambling is associated with an increased risk for experiencing gambling-related harms, driving calls for more effective, personalized harm prevention initiatives. Such initiatives depend on the development of models capable of detecting at-risk online gamblers. We aimed to determine whether machine learning algorithms can use site data to detect retrospectively at-risk online gamblers indicated by the Problem Gambling Severity Index (PGSI). Exploratory comparison of six prominent supervised machine learning methods (decision trees, random forests, K-nearest neighbours, logistic regressions, artificial neural networks and support vector machines) to predict problem gambling risk levels reported on the PGSI. Lotoquebec.com (formerly espacejeux.com), an online gambling platform operated by Loto-Québec (a provincial Crown Corporation) in Quebec, Canada. N = 9145 adults (18+) who completed the survey measure and placed at least one bet using real money on the site. Participants completed the PGSI, a self-report questionnaire with validated cut-offs denoting a moderate-to-high-risk (PGSI 5+) or high-risk (PGSI 8+) for experiencing past-year gambling-related problems. Participants agreed to release additional data about the preceding 12 months from their user accounts. Predictor variables (144) were derived from users' transactions, apparent betting behaviours, listed demographics and use of responsible gambling tools on the platform. Our best classification models (random forests) for the PGSI 5+ and 8+ outcome variables accounted for 84.33% (95% CI = 82.24-86.41) and 82.52% (95% CI = 79.96-85.08) of the total area under their receiver operating characteristic curves, respectively. The most important factors in these models included the frequency and variability of participants' betting behaviour and repeat engagement on the site. Machine learning algorithms appear to be able to classify at-risk online gamblers using data generated from their use of online gambling platforms. They may enable personalized harm prevention initiatives, but are constrained by trade-offs between their sensitivity and precision.

Qualitative Experience of Self-Exclusion Programs: A Scoping Review

Gambling disorder is a major public health issue in many countries. It has been defined as a persistent, recurrent pattern of gambling and is associated with substantial distress or impairment, lower quality of life, and living with a plurality of psychiatric problems. Many people suffering from gambling disorder seek help in ways other than formal treatment seeking, including self-management strategies. One example of responsible gambling tools that has gained popularity in recent years is self-exclusion programs. Self-exclusion entails individuals barring themselves from a gambling venue or a virtual platform. The aim of this scoping review is to summarize the literature on this topic and to explore participants' perceptions and experiences with self-exclusion. An electronic literature search was conducted on 16th May 2022 in the following databases: Academic Search Complete, CINAHL Plus with Full Text, Education Source, ERIC, MEDLINE with Full Text, APA PsycArticles, Psychology and Behavioral Sciences Collection, APA PsychInfo, Social Work Abstracts, and SocINDEX. The search yielded a total of 236 articles, of which 109 remained after duplicates were removed. After full-text reading, six articles were included in this review. The available literature shows that although there are many barriers and limitations to the current self-exclusion programs, self-exclusion is generally viewed as an effective responsible gambling strategy. There is a clear need to improve the current programs by increasing awareness, publicity, availability, staff training, off-site venue exclusion, and technology-assisted monitoring, as well as by adopting more holistic management approaches to gambling disorders in general.

Cooling Off and the Effects of Mandatory Breaks in Online Gambling: A Large-Scale Real-World Study

The prevention of problematic online gambling behavior is a topic of major interest for regulators, the gambling industry, and researchers. Many gambling operators approach this issue by using responsible gambling tools. Among such tools, mandatory play breaks are used to interrupt long online gambling sessions, providing “cooling off” periods for players to take a reflective “time out”. The present study investigated the effects of mandatory play breaks in a large-scale experiment with 23,234 online gamblers engaging in more than 870,000,000 gambling transactions on Norsk Tipping’s gambling platform over a 1-month period. The gamblers were randomly assigned to several intervention groups with varying duration of mandatory play breaks and one control group with Norsk Tipping’s standard play break duration. More specifically, the study analyzed the relationship between the mandatory break received and the gambler’s acceptance of this tool, the interaction patterns with the tool, and how quickly they started to gamble again, as well as post-intervention effects on gambling behavior. Results showed that gamblers who were treated with longer mandatory breaks (i) tended to take longer voluntary breaks, and (ii) interacted more frequently with the tool (for instance, by clicking the “logout” button). Furthermore, gamblers appeared to accept longer mandatory play breaks. However, only a fraction of post-intervention effects remained, and mainly only for gamblers who received a substantial number of long mandatory play breaks. Overall, the present study provides actionable insights for both researchers and the gambling industry to improve the effectiveness of mandatory play breaks as a responsible gambling tool.

The Impact of Personalized Feedback Interventions by a Gambling Operator on Subsequent Gambling Expenditure in a Sample of Dutch Online Gamblers

Player protection has become an important area for the gambling industry over the past decade. A number of gambling regulators now require gambling operators to interact with customers if they suspect they are gambling in a problematic way. The present study provided insight on the impact of personalized feedback interventions (PFIs) on subsequent gambling behavior among a Dutch sample of real-world gamblers. Nederlandse Loterij (the national Dutch Lottery operator) provided access to a secondary dataset comprising tracking data from online casino and sports betting gamblers (N = 2,576) who were contacted either by e-mail or telephone between November 2021 and March 2022 if they showed signs of problematic gambling as identified using behavioral tracking software. Compared to matched controls (n = 369,961 gamblers), Dutch gamblers who received a PFI (via e-mail [n = 1876] or a telephone call [n = 700]) from the gambling operator had a significant reduction in amount of money deposited, amount of money wagered, number of monetary deposits, and time spent gambling in the 30 days after being contacted. Gambling frequency as measured by the number of gambling days did not change significantly after a PFI. Telephone calls did not lead to a significant larger reduction with respect to the aforementioned behavioral metrics. High-intensity players reduced their gambling behavior as frequently as low-intensity players, which means that the intervention’s success was independent of gambling intensity. The impact on subsequent gambling was the same across age groups and gender. The results of the present study are of use to many different stakeholder groups including researchers in the gambling studies field and the gambling industry as well as regulators and policymakers who can recommend or enforce that gambling operators utilize responsible gambling tools such as using PFIs to those who may be displaying problematic gambling behaviors as a way of minimizing harm and protecting gamblers.

Quitting while you're ahead: Evidence for individual gambling thresholds from a survey of Massachusetts Gamblers

Although key stakeholders have discussed responsible gambling tools and protective behavioral strategies for years, evaluations of their effectiveness are still limited. Among protective behavioral strategies are individual gambling thresholds, typically on monetary losses or time spent gambling, after which a person stops gambling. A novel, counter-intuitive alternative, a monetary win threshold, also might hold value. Simulations have shown that, like monetary loss or time thresholds, win thresholds reduce the amount of time spent gambling and therefore also limit average expected gambling losses. Yet, little is known about gamblers’ use of gambling thresholds. In this paper, we examine data from an internet panel survey of past-year gamblers in Massachusetts to better understand the characteristics of those individuals who are more likely to use and adhere to loss and win thresholds. We observed that individuals who had engaged in recreational drug use were less likely to adopt gambling thresholds. Individuals who had previously received a positive screen for depression, and who travelled to out-of-state casinos were more likely to use gambling thresholds. In analyzing the adherence to gambling thresholds, we found that individuals who adhered to their loss thresholds were less likely to use ATMs during gambling sessions. Finally, individuals who engaged in hazardous drinking were less likely to adhere to their own win thresholds. This study adds to the literature by providing evidence related to the characteristics of gambling threshold users and contributes some of the only evidence in the literature on the actual use of monetary win thresholds.

Attitude Towards Deposit Limits and Relationship with Their Account-Based Data Among a Sample of German Online Slots Players

Social responsibility and duty of care have become major cornerstones for gambling operators. This has led to the introduction of many different responsible gambling tools such as limit-setting, mandatory play breaks, and personalized messaging. In the present study, the authors were given access to two secondary datasets provided by a German online slots game operator. The first dataset was from an online survey carried out by the gambling operator among 1000 of its players concerning their attitude towards deposit limits as well as self-reported problem gambling. In addition to the survey responses, the authors were given access to a second dataset of account-based data concerning each customer’s wagers, wins, monetary deposits, and monetary withdrawals. These datasets were then combined. The majority of players had a positive attitude towards the maximum deposit monthly deposit limit which was introduced by the German State Treaty on Gambling in 2021. Players who disagreed with the maximum monthly deposit limit, deposited significantly more money in the 30 days prior to answering the survey questions compared to players who agreed with the monthly deposit limit. The tracking data found only 7.6% of players had deposited the maximum amount of money allowed in one month. However, 60.5% of players in the survey data said that they did so. Players who said that they continued to gamble after reaching the deposit limit wagered and deposited significantly more money in the 30 days prior to the survey compared to players who said they stopped gambling after reaching the deposit limit. Two-fifths of players said they continued to gamble after reaching the monthly deposit limit (42%). The majority of the players said they chose a personal deposit limit because it helped them to better control their gambling expenditure. A quarter of the players reported gambling problems using the Brief Biosocial Gambling Screen (27%). Self-reported problem gambling was not correlated with depositing, wagering or any other player tracking metric.

Predicting self-exclusion among online gamblers: An empirical real-world study

Protecting gamblers from problematic gambling behavior is a major concern for clinicians, researchers, and gambling regulators. Most gambling operators offer a range of so-called responsible gambling tools to help players better understand and control their gambling behavior. One such tool is voluntary self-exclusion, which allows players to block themselves from gambling for a self-selected period. Using player tracking data from three online gambling platforms operating across six countries, this study empirically investigated the factors that led players to self-exclude. Specifically, the study tested (i) which behavioral features led to future self-exclusion, and (ii) whether monetary gambling intensity features (i.e., amount of stakes, losses, and deposits) additionally improved the prediction. A total of 25,720 online gamblers (13% female; mean age = 39.9 years) were analyzed, of whom 414 (1.61%) had a future self-exclusion. Results showed that higher odds of future self-exclusion across countries was associated with a (i) higher number of previous voluntary limit changes and self-exclusions, (ii) higher number of different payment methods for deposits, (iii) higher average number of deposits per session, and (iv) higher number of different types of games played. In five out of six countries, none of the monetary gambling intensity features appeared to affect the odds of future self-exclusion given the inclusion of the aforementioned behavioral variables. Finally, the study examined whether the identified behavioral variables could be used by machine learning algorithms to predict future self-exclusions and generalize to gambling populations of other countries and operators. Overall, machine learning algorithms were able to generalize to other countries in predicting future self-exclusions.

Time out: Prediction of self-exclusion from daily fantasy sports.

Responsible gambling (RG) tools that include play management software, self-limit features, and self-exclusion are relatively common offerings on major online gambling platforms. However, how online gaming and daily fantasy sports (DFS) players use such tools is less clear. The goals of this article were to understand how players use self-exclusion at a major DFS platform and to identify DFS activity-related predictors of self-exclusion. During November 2015, DraftKings, a major DFS provider, rolled out a self-exclusion feature that allows players to self-exclude from the platform for a specified amount of time, up to 5 years. We used player records from DraftKings, examining play patterns and self-exclusion across 3 + years of data. We found that less than 0.5% of subscribers in our sample self-excluded during the study period and almost one third of those who self-excluded did so more than once. In general, self-excluders engaged with a greater variety of contests and sports and entered contests with higher entry fees than those who did not self-exclude. Repeat self-excluders selected shorter initial self-exclusion terms and also engaged with a greater variety of game types and sports than one-time self-excluders. However, self-excluders did not engage in riskier contests or experience higher percent losses. Our findings have implications for our understanding of RG feature use among DFS subscribers and markers of risk for experiencing problems with DFS and gambling more generally.

The Effect of a Mandatory Play Break on Subsequent Gambling Behavior among British Online Casino Players: A Large-Scale Real-World Study

In recent years, various novel responsible gambling (RG) tools have been implemented to aid harm-minimization. One such RG tool has been the implementation of enforced mandatory play breaks. Despite many responsible gambling operators using mandatory play breaks, only three previous studies have examined their efficacy and the findings were mixed. Therefore, the present investigation was a large-scale real-world study which was designed to see whether a 60-minute mandatory play break influenced subsequent depositing and wagering. The authors were given access to 27 days of player data prior to the introduction of a mandatory play break and 27 days of player data after the mandatory play break was introduced. The study comprised British online gamblers from Skillonnet (a European online gambling operator). Between July 23 and September 15 (2021), 2,021 players deposited at least ten times or more on a calendar day, at least once. The 2,201 players generated 2,994 corresponding events (i.e., the depositing of money at least 10 times in one day). The percentage of players who stopped depositing money as a consequence of the mandatory play break rose from 27% to 68% on the day of a play break. Moreover, the percentage of players who stopped wagering as a consequence of the mandatory play break rose from 0.1% to 45% on the day of a play break. The findings of the present study demonstrated that a 60-minute mandatory play break impacts players’ depositing and wagering immediately after the play break. This means that a mandatory hour-long play break in an online casino setting appears to prevent overspending during a short period of time. The effects of a 60-minute mandatory break on the next day’s behavior were inconclusive.

Analyzing Consumer Protection for Gamblers Across Different Online Gambling Operators: A Replication Study

Online gambling is a growing business with many stakeholders. Due to the fact that a small proportion of gamblers develop problems, responsible gambling (RG), player protection, and harm minimization have become core areas for gambling regulators. The present study replicated a previous one carried out by Bonello and Griffiths in 2017 to determine whether there had been any significant changes by leading gambling operators due to increased regulatory pressures over the past few years. Fifty leading online gambling operators were audited in relation to their RG practices as well as engaging with their customer services by posing as a problem gambler. Results indicated that overall RG practices appeared to have improved in the past 3 years based on the information in dedicated RG webpages, the increase in RG tool availability, and the communication with customer services. Despite the fact that RG practices appear to have improved, there were still areas for improvement.

The Effect of Mandatory Play Breaks on Subsequent Gambling Behavior Among Norwegian Online Sports Betting, Slots and Bingo Players: A Large-scale Real World Study

In order to protect gamblers, gambling operators have introduced a wide range of responsible gambling (RG) tools. Mandatory play breaks (i.e., forced termination of a gambling session) and personalized feedback about the gambling expenditure are two RG tools that are frequently used. While the motivation behind mandatory play breaks is simple (i.e., gambling operators expect gamblers to reduce their gambling significantly as a result of an enforced break in play), empirical evidence supporting the efficacy of the mandatory breaks is still limited. The present study comprised a real-world experiment with the clientele of Norwegian gambling operator Norsk Tipping. On the Norsk Tipping gambling website, which offers slots, bingo and sports-betting, forced termination occurs if gamblers have played continuously for a one-hour period. The study tested the effect of different lengths of mandatory play breaks (90 s, 5 min, 15 min) on subsequent gambling behavior, as well as the effect of combined personalized feedback concerning money wagered, won, and net win/loss. In total 21,129 online players (61% male; mean age = 47.4 years) experienced at least one play break between April 17 and May 21 (2020) with 156,989 mandatory play breaks in total. Results indicated that a 15-min mandatory play break led to a disproportionately longer voluntary play pause compared to 5-min and 90-s mandatory play breaks. Personalized feedback appeared to have no additional effect on subsequent gambling and none of the mandatory play breaks appeared to affect the increase or decrease in money wagered once players started to gamble again.

Applying the DSM-5 Criteria for Gambling Disorder to Online Gambling Account-Based Tracking Data: An Empirical Study Utilizing Cluster Analysis

The emergence of online gambling has raised concerns about potential gambling-related harm, and various measures have been implemented in order to minimise harm such as identifying and/or predicting potential markers of harm. The present study explored how the nine DSM-5 criteria for gambling disorder can be operationalised in terms of actual online gambling behaviour using account-based gambling tracking data. The authors were given access to an anonymised sample of 982 gamblers registered with an online gambling operator. The data collected for these gamblers consisted of their first three months’ gambling activity. The data points included customer service contacts, number of hours spent gambling, number of active days, deposit amounts and frequency, the number of times a responsible gambling tool (such as deposit limit) were removed by the gamblers themselves, number of cancelled withdrawals, number of third-party requests, number of registered credit cards, and frequency of requesting bonuses through customer service (i.e., the number of instances of ‘bonus begging’). Using these metrics, most of the DSM-5 criteria for gambling disorder can be operationalized (at least to some extent) using actual transaction data. These metrics were then applied to a sample of online gamblers, and through cluster analysis four types of online gambler based on these metrics (non-problem gamblers, at-risk gamblers, financially vulnerable gamblers, and emotionally vulnerable gamblers) were identified. The present study is the first to examine the application of the DSM-5 criteria of gambling disorder to actual gambling behaviour using online gambling transaction data and suggests ways that gambling operators could identify problem gamblers online without the need for self-report diagnostic screening instruments.

Gamblers’ Perception of the Playscan Risk Assessment: A Mixed-Methods Study

Responsible gambling (RG) tools are globally widespread; they aim to prevent or decrease the harm caused by gambling. However, existing research suggests that several included features do not decrease gambling or significantly reduce the subsequent harm. Most of the previous studies have used gambling data to understand the changes in gambling behavior. However, the literature lacks research regarding gamblers’ experience and perception of RG tools, which may provide insight into increasing the usage and effectiveness of RG tools. This mixed-methods study aimed to explore gamblers’ perception of their risk assessment in the RG tool Playscan regarding developing harmful gambling problems. Overall, 757 participants rated the perceived accuracy of their risk assessment and their perception of the overall RG tool that conducted the assessment. Participants were also allowed to leave a comment providing feedback, which was analyzed using thematic analysis. Quantitative data was analyzed using logistic regression and structural equation modeling. Qualitative analyses revealed that most of the participants were pleased with the risk assessment and found it helpful. Moderated mediation analysis showed that participants’ assessment agreement partially mediated the association between expressing a negative view and their general view of Playscan. These results highlight the need to decrease the level of disagreement for promoting a better general view of RG tools to potentially increase their usage and effectiveness.

Social Facilitation Among Gamblers: A Large-Scale Study Using Account-Based Data

Previous research suggests that the presence of other gamblers in a gambling venue intensifies individual gambling behavior. To study such potential social facilitation among gamblers, we conduct a large-scale analysis of more than one million gambling sessions using player tracking data of the Norwegian gambling operator Norsk Tipping. In particular, we empirically assess the existence and strength of this facilitation, and how it manifests in differently utilized gambling venues. In our study, we control for (i) each individual's co-gamblers (frequent vs. occasional co-gamblers) and for (ii) the magnitude of individual's social participation (social seeking vs. social avoiding gamblers). We find that gamblers stake more money and play longer sessions the more crowded the venues get and that social avoiding gamblers gamble more when they play with their most-frequent co-gambler. Interestingly, our results strongly indicate that social avoiding gamblers are more susceptible to social facilitation than gamblers who are familiar with crowded gambling venues. Overall, our research is the first large-scale study of social facilitation among gamblers introducing a novel framework to empirically measure this effect. We believe that our work will have important practical implications for both gambling behavior researchers as well as the gambling industry in designing and evaluating responsible gambling tools.

Commentary on Heirene & Gainsbury: Re-thinking prevention in the gambling field through applying the triad universal, selective and indicated preventions.

Re-thinking the prevention of gambling-related harms by applying the triad of universal, selective and indicated prevention approaches could better target initiatives to populations. Heirene & Gainsbury promote an indicated prevention approach to encourage limit-setting, and targeting this to an appropriate time in the gambling course could optimize its acceptability by operators and effectiveness. Alcohol and substance use disorder fields tend to conceptualize prevention as ‘universal’ (offered to the whole population), ‘selective’ (targeting subpopulations with biological, psychological and/or socio-cultural risk factors) and ‘indicated’ (targeting people who are engaging in hazardous behaviours and have precursors or symptoms of substance use disorder) [1-4]. Indicated prevention programmes seek to refer people to appropriately matched brief or more intensive treatment interventions. The gambling field has developed its own prevention framework using the concept of ‘responsible gambling’ [5]. Responsible gambling was developed as a harm reduction approach to accommodate the divergent interests of gambling stakeholders, and is similar to very early models of alcohol harm reduction [6]. As discussed by Heirene & Gainsbury [7], contemporary responsible gambling approaches typically promote ways in which people can use tools to set limits to their wagering or self-exclude from gambling altogether. These are usually implemented through a selective prevention approach, although there is passive targeting of all gamblers. There is evidence that gambling operators assume that these prevention measures are sufficient [8]. However, additional prevention interventions providing information and better decision-making have been proposed to target causal, frequent and intensive gambling groups [9, 10]. Re-thinking prevention in the gambling field via a triad of universal, selective and indicated preventions could guide existing and future prevention initiatives in gambling, personalized to the targeted population. For instance, some tools could be more relevant in an indicated approach, targeting gamblers who have impairments in cognitive control. Self-exclusion is a good example, because previous research suggests that this action mainly appeals to people with a gambling disorder [11-13]. Nevertheless, it is still considered as a responsible gambling tool in a selective prevention approach for all gamblers. Developing self-exclusion in an indicated approach would provide the opportunity to proactively propose self-exclusion to highest risk gamblers, screened using validated tools, and further involve them in dedicated therapeutic interventions when needed. In their study [7], Heirene & Gainsbury tested a proactive message promoting limit-setting to all gamblers without a limit set (i.e. a group with a risky gambling pattern of use, placing their intervention in a proactive and selective prevention approach). An important finding was that the largest predictor of limit-setting was having previously set and then removed a limit. People who remove previous set limits will probably do so because either the limit was too low or because they are now experiencing symptoms of gambling disorder (GD) [14]. Further, this finding suggests that proactive limit-setting after the initial period of gambling on an operator's website could be effective in an indicated prevention approach for people with early symptoms of GD. The fact that once a responsible gambling tool is used it is more easily re-used supports previous findings on self-exclusion [15]. Heirene & Gainsbury discuss their findings in the light of previous data targeting gamblers with hazardous behaviours [16]. Although we should recognize that gambling operators may be resistant to displaying messages repeatedly so that their products have less appeal [6], there are important opportunities to further develop this approach to help prevent gambling-related harm. The triad of indicated, selective and universal prevention provides the opportunity to optimize effectiveness, feasibility in real life and acceptability of interventions. None.

Further Exploration of the Psychometric Properties of GamTest: A Rasch Analysis.

GamTest is a self-rating scale of negative consequences of gambling, included in the popular responsible gambling tool Playscan as part of an overall risk assessment and feedback feature. Two previous psychometric evaluations of this instrument yielded contradictory results: in an online high-gambling population, a five-factor model was supported and the instrument had overall good psychometric properties, but in a low-gambling population, the same factor structure was not supported. Because GamTest is used with both low- and high-gambling populations, more psychometric research is needed to fully understand how the instrument works. The current study examined, for the first time, psychometric performance among a sample of low-gambling respondents using a Rasch analysis. Results indicated that the instrument could be improved by decreasing the scale-steps and removing several problematic items demonstrating misfit. Furthermore, the findings indicated that some items functioned differently depending on gender, and that a shortened, improved nine-item version could not differentiate between different levels of risk. Our findings suggest that the instrument would arguably benefit from being adapted for use in a low-gambling population.
