Xiao LY, Fraser TC, Nielsen RKL, Newall PWS. Loot boxes, gambling-related risk factors, and mental health in Mainland China: A large-scale survey. Addict Behav 2024; 148:107860.

Abstract
Loot boxes can be bought with real-world money to obtain random content inside video games. Loot boxes are viewed by many as gambling-like and are prevalently implemented globally. Previous Western and international studies have consistently found loot box spending to be positively correlated with problem gambling. Previous Western studies presented mixed results as to the correlations between loot box purchasing and gambling-related risk factors, mental wellbeing, and psychological distress. A large-scale survey of adult video game players from the People's Republic of China (PRC) (N = 2601) was conducted through Tencent Survey. The positive correlations between loot box spending and problem gambling, and between loot box spending and problem videogaming, were successfully replicated. However, other potential risk factors (i.e., impulsivity/impulsiveness; binary past-year gambling participation status; and sensation-seeking tendencies) either did not positively correlate with loot box spending or only did so weakly. Contrary to expectations, high impulsivity was negatively associated with loot box engagement. The Risky Loot Box Index (RLI) most strongly positively correlated with, and was the best predictor in multiple linear regression models for, loot box spending. The RLI may be effective at measuring loot box harms cross-culturally. A surprising weak positive correlation was found between loot box engagement and PRC players' mental wellbeing, and high psychological distress unexpectedly negatively predicted loot box purchasing. Although gambling-like, the risk and protective factors of loot boxes are seemingly different, meaning they should rightfully be treated as novel products. Cross-cultural research can contribute to a better understanding of loot box harms.

Abstract
The COVID-19 pandemic and the measures to prevent its spread have had a negative impact on substance use behaviour. It is likely that social distancing and lockdown measures have also altered gambling behaviour, for instance shifting from land-based to online gambling. We used large-scale web scraping to analyse posting behaviour on a major German online gambling forum, gathering a database of more than 200k posts. We examined the usage of different subforums, i.e. terrestrial, online gambling and problem gambling sections, and changes in posting behaviour related to the casino closures that were part of the nationwide restrictions in Germany in 2020. There was a marked increase in newly registered users during the first lockdown compared to the preceding weeks, an increase in the number of posts in the online gambling subforum and concurrent decrease in the terrestrial gambling subforum. Further, the number of short-latency replies was higher during the first lockdown compared to the preceding weeks. Many users who posted in both the online and terrestrial forum contributed at least once to the problem gambling subforum, implying that the topic of problem gambling is widely discussed. Our findings may indicate a shift from terrestrial to online gambling during lockdown, and mirror the general increase in screen time and usage of online platforms after the onset of the COVID-19 pandemic. The analyses help to identify lockdown-related effects on gambling behaviour. These potentially detrimental effects pose a special threat for individuals at risk and may require monitoring and special public health measures.

Abstract
This research empirically tests the relationship between gambling-related cognitive distortions and the development of gambling problems. In two separate studies using methodologies designed to support non-experimental causal inference, we demonstrate that holding false beliefs about gambling experiences is related to current and future risk of developing problems with gambling. In our first study, we use an instrumental variable estimation strategy on an internet sample (n = 184) and observe a statistically significant relationship between Gamblers' Belief Questionnaire scores and measures of loss chasing, overspending, and gambling problems. These findings were robust to linear and ordinal estimation strategies and multiple model specifications. In our second study, we examine five-year prospective longitudinal data (n = 1,431) to validate our initial findings and test whether irrational thoughts are also related to future problems with gambling. While controlling for current fallacies, we find that past Gambling Fallacies Measure scores are related to present gambling problems across two survey waves. The effect size of each of the past fallacy levels is roughly half of the effect size of present levels, suggesting meaningful impacts. Our findings support the Pathways Model of Problem and Pathological Gambling.

Duan Y, Xu S, Wang Y, Zhang Y, Wang Y, Chen R. Blind box over-engagement and suicide risk among adolescents and young adults: Results of a large-scale survey. EClinicalMedicine 2022; 51:101575. [PMID: 35875818 PMCID: PMC9304904 DOI: 10.1016/j.eclinm.2022.101575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 07/01/2022] [Accepted: 07/01/2022] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Gambling appears to be an independent risk factor for suicide among the young population worldwide. Blind boxes are collectable toys packed randomly in the box, which share certain similarities with gambling and are popular among the young population. This is the first study that examined the association between blind box engagement and suicide risk in the young population, the leading consumption group of blind boxes. METHODS This study is part of a large-scale, cross-sectional study using convenience sampling conducted Oct 26 to Nov 18, 2021, which covered all the university and college students in the Jilin province, China. A total of 73,206 participants completed the survey with valid data for the current study (male: N = 28,762; female: N = 44,444; Mean age = 19·59). Participants' blind box engagement, suicide risk, depression, anxiety, alcohol use, smoking habit, and sociodemographic characteristics were assessed. First, we used univariate and multivariable binary logistic regression models to examine the relationship between blind box engagement and suicide risk in all participants. Second, we tested whether depression and anxiety would mediate the association between blind box engagement and suicide risk. Third, we analysed the association between "Frequency (i.e., frequency of blind box engagement)," "Bet (i.e., expenditure on the blind box that exceeds affordability)," "Tolerance (i.e., level of addiction)," "Borrowed (i.e., the amount of money borrowed for blind box engagement)," and suicide risk in the group with blind box engagement history. FINDINGS 4,195 participants (5·73%) have engaged in blind boxes, with 3,255 females (77·59%) and 940 males (22·41%). In the univariate models, binary logistic regression showed that blind box engagement was associated with suicide risk in both male and female participants (male: OR = 2·21, 95% CI = 1·86-2·63; female: OR = 1·64, 95% CI = 1·50-1·78). In the multivariable models, after controlling age, subjective socioeconomic status, per capita disposable income, alcohol use, and smoking habit, blind box engagement still was associated with suicide risk across genders (male: OR = 2·25, 95% CI = 1·89-2·68; female: OR = 1·58, 95% CI = 1·45-1·73). Depression (male: indirect effect = 0·31, SE = 0·04, p < 0·001; female: indirect effect = 0·20, SE = 0·02, p < 0·001) and anxiety (male: indirect effect = 0·26, SE = 0·03, p < 0·001; female: indirect effect = 0·13, SE = 0·02, p < 0·001) mediate the association between blind box engagement and suicide risk. Within the blind box engagement group, forward binary logistic regression revealed that "Tolerance" was associated with participants' suicide risk in both males (p = 0·001) and females (p < 0·001); "Borrowed" (p = 0·019) alone was associated with the male participants' suicide risk. INTERPRETATION Our findings showed that blind box over-engagement is positively associated with suicide risk in both young males and females, and this association persisted after adjusting for influencing factors. In spite of the limitations in this study (e.g., cross-sectional, convenience sampling), current findings can assist policymakers in developing regulations for such a prosperous youth-dominant consumption industry while protecting youth's mental health worldwide. FUNDING None.

Opening Pandora’s Loot Box: Weak Links Between Gambling and Loot Box Expenditure in China, and Player Opinions on Probability Disclosures and Pity-Timers. J Gambl Stud 2022; 39:645-668.

Abstract
AbstractLoot boxes are quasi-gambling virtual products in video games that provide randomised rewards of varying value. Previous studies in Western contexts have identified a positive correlation between loot box purchasing and problem gambling severity. A preregistered survey of People’s Republic of China (PRC) video game players (N = 879) failed to replicate this correlation. We observed statistically significant but weak positive correlations between loot box expenditure and past-year gambling participation, and between loot box expenditure and impulsiveness. This study cannot prove that loot boxes are not disproportionately purchased by people with problem gambling symptomatology in the PRC or that PRC players are not potentially at risk of loot box-related harms. Instead, the evidence suggests that the relationship between loot boxes and gambling might be weaker in the PRC than in Western countries. We identified multiple unique factors about the PRC that might be affecting this relationship. For example, the lotteries are the only legally permitted form of gambling. More gamified electronic gambling products are unavailable. The limited availability of gambling meant that a low level of gambling participation (n = 87) was observed, which is a limitation of this study. Additionally, the PRC is presently the only country to legally require loot box probability disclosures as a consumer protection measure. Most loot box purchasers (84.6%) reported seeing loot box probability disclosures, but only 19.3% of this group reported consequently spending less money. Most loot box purchasers (86.9%) thought that pity-timers, which increase the winning probabilities of obtaining rarer rewards, are appropriate for implementation. Future loot box research should give greater consideration to differing cultural contexts and novel consumer protection measures.

Abstract
OBJECTIVE The objective of this study is to explore the association of problem gambling with demographics, psychological distress, and gaming behavior in young adult gacha gamers in Hong Kong. MATERIALS AND METHODS Cross-sectional data was collected in the first and fifth waves of COVID-19 pandemic in Hong Kong online. Participants who aged 18-25 years and had been playing gacha games over the past 12 months were recruited. Stepwise multiple regression was used to explore the association among risk of problem gambling, gaming behavior, participation in gaming activities and psychological distress. A two-sided p-value <0.05 was considered as statistical significance. RESULTS Three hundred and thirty-seven completed questionnaires were received with no missing data. 34.7% (n = 117) of the participants had non/low-risk of problem gambling. About 40% (n = 136) of them had moderate-risk and the remaining 25% (n = 84) were at high risk of problem gambling. A higher proportion of female participants (78.6%) were found in high-risk group as compared to 39.7% and 55.6% only in the non/low-risk and moderate-risk groups, respectively. The regression model (R 2 = 0.513, F = 71.895, p < 0.001) showed that 51.3% of the variance of the total problem gambling score could be explained by stress, anxiety, monthly expenses on gacha purchases, number of motives for gacha purchase and number of gambling activities engaged. CONCLUSION The present study provides empirical evidence to support the association between problem gambling and microtransaction especially for gacha which is the most popular type of video game microtransaction in Asia. The established regression model suggests that gacha gamers with higher risk of problem gambling tend to have greater stress, higher anxiety level, spend more on gacha purchase, have more motives for gacha purchases and engage in more gambling activities. In contrast to the extant literature, higher proportion of female participants in high-risk group indicates that female gacha gamers are also at very high risk of becoming problem gamblers.

Abstract
Background Social media is an important and growing part of the lives of the vast majority of the global population, especially in the young. Although still a young and scarce subject, research has revealed that social media has addictive potential. The aim of this cross-sectional study was to explore the associations between problematic use of social media and mental distress, problematic gaming and gambling, within the Swedish general population. Methods Data from 2,118 respondents was collected through self-report questions on demographics and validated scales measuring addiction-like experiences of social media, problem gaming, problem gambling, and mental distress. Associations were analyzed in unadjusted analyses and–for variables not exceedingly inter-correlated–in adjusted logistic regression analyses. Results In adjusted analyses, problematic use of social media demonstrated a relationship with younger age, time using instant messaging services, and mental distress, but not with education level, occupational status, or with treatment needs for alcohol or drug problems. Behavioral addictions (internet, gaming and gambling) were substantially inter-correlated, and all were associated with problematic use of social media in unadjusted analyses. Conclusions Social media use is associated with other addictive behaviors and mental distress. While factors of causality remain to be studied, these insights can motivate healthcare professionals to assess social media habits, for example in individuals suffering from issues concerning gambling, gaming or mental health.

Changes of Gambling Patterns during COVID-19 in Sweden, and Potential for Preventive Policy Changes. A Second Look Nine Months into the Pandemic. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18052342.

Abstract
Gambling has been suggested as one of the potential mental health consequences of the COVID-19 pandemic. In earlier self-report studies, increased gambling has been reported by a limited proportion of respondents characterized with a high degree of problem gambling. The present study, carried out with the same methodology and in the same geographical setting, around seven months later in the pandemic, aimed to repeat and to extend the understanding of potential gambling changes in the population during COVID-19. An anonymous sample of web panel members was assessed, altogether 2029 individuals (52% women, 10% moderate-risk or problem gamblers). Results indicated that 6% reported increased gambling, and 4% reported decreased gambling during the pandemic. Having increased gambling was associated with more severe gambling problems (OR 2.78, 95% confidence interval 2.27–3.40), increased alcohol consumption (OR 2.92, 1.71–4.98), and psychological distress (OR 3.38, 1.83–6.23). In the group reporting increased gambling during COVID-19, moderate-risk/problem gambling was very common (62%). Recent governmental policy interventions in the area were known to a minority (30%) of respondents, but awareness of the regulations was markedly more common in individuals with at least moderate-risk gambling (56%) and in self-excluders (78%). Reporting of any perceived influence from policy changes was low (3%), and divided between those reporting an increasing and decreasing effect, respectively. Increased gambling may be a consequence of COVID-19-related changes in everyday lives of individuals with problematic gambling patterns. Thus, a vulnerable group demonstrates higher rates of gambling migration and psychosocial problems, and may require particular attention in screening and treatment contexts, and further scientific evaluations.

Abstract
Prevalence studies on gambling participation and problem gambling in Japan have been limited. To obtain data showing the current status of gambling in Japan, we conducted an online survey on gambling participation and problem gambling among residents in Chiba City. The online data collection was conducted through an Internet research firm. Questionnaires were consisted of personal demographics, past-year gambling participation and severity of gambling risks. The Problem Gambling Severity Index (PGSI) was used as a survey instrument. Males (51.5%) were significantly more likely than females (25.5%) to have gambled in the past year. Problem gamblers (PGSI score ≧ 8) were 7.2% among males and 1.2% among females. Problem gambling was strongly correlated with frequent gambling, preference for Pachinko/Slot and smoking habit. The gambling participation rates were roughly lower than those reported in many overseas jurisdictions, whereas the problem gambling rates were considerably higher than those reported in the same jurisdictions. According to the total consumption model, it would be reasonable to consider that gambling participation rates show a positive correlation with problem gambling rates. The high levels of problem gambling may be due to the administration mode using online sampling, by which answers admitting unapprovable behaviors like problem gambling tend to increase. This suggests that the previous studies using conventional face-to-face or telephone methods may have underestimated problem gambling rates.

Abstract
The aim of this study was to determine the moderating effects of sociodemographic characteristics, substance use, and psychosocial problems on the relationship between perceived gambling availability and problem gambling severity. Bivariate and multivariate regression analyses of the 2008 and 2009 Social and Economic Impacts of Gambling in Alberta surveys found problem gambling severity was 1.25-1.39 times higher for those reporting gambling opportunities were 'too widely available'. Factors such as age, gender, place of residence, and psychosocial problems had significant moderating effects. Our findings indicate that the perception of gambling availability has a statistically significant impact on problem gambling severity.

Abstract
To examine the underlying dimensionality and structure of problem gambling using a comprehensive range of problem gambling assessments from an international online survey of gamblers. A total of 12,521 gamblers from 105 countries were recruited through banner advertising placed on a popular online gambling portal to take an online survey. Although participants were recruited online, the majority of the sample (71.6%) gambled only at land-based venues in the past 12 months. A total of 5081 individuals completed all items from the four problem gambling assessments. Participants were allocated to answer one of the four problem gambling assessments and the remaining unique items from the three other problem gambling assessments. The order of assessments were counterbalanced. Two optimal scaling procedures were independently employed to estimate the number of dimensions within the data: exploratory categorical principal component bootstrap analysis and multidimensional scaling. Nonlinear canonical correlation was then used to establish how well each of the four assessment instruments captured the identified dimensions. A final confirmatory principal component analysis was run to understand and characterise the nature of the dimensions that were identified. Both the categorical principal component bootstrap analysis and multidimensional scaling indicated the data was multidimensional, with four dimensions (including a single dominant dimension) providing the best characterisation of the data. The nonlinear canonical correlation analysis found that the Problem and Pathological Gambling Measure and the National Opinion Research Center DSM-IV Screen for Gambling Problems operationalization of the Diagnostic and Statistical Manual of Mental Disorders Four (DSM-IV) criteria best captured these multiple dimensions. Confirmatory principal component analysis suggest a core experience of generic problem gambling symptomology and three other components: "financial problems", "health and relationship issues", and "difficulty controlling gambling". Problem gambling symptomology appears to be multi-dimensional. Certain assessments capture this heterogeneity better than others and thereby provide a more complete and accurate assessment of this construct.

Abstract
BACKGROUND The Problem Gambling Severity Index (PGSI) has been the most frequently used instrument for prevalence studies of problem gambling in the 2010s. However, the Japanese version of the PGSI has yet to be developed. OBJECTIVE To develop the Japanese version of the PGSI and to investigate its reliability and validity. MATERIALS AND METHODS We translated and back-translated the original version of the PGSI into Japanese. The author of the original PGSI confirmed the semantic equivalence between the original PGSI and its Japanese version. We examined the reliability and validity of the Japanese version of the PGSI using data from a nationwide prevalence study of problem gambling conducted in Japan in 2017. RESULTS Usable responses were obtained from 5365 residents. The PGSI had excellent internal consistency (Cronbach's alpha coefficient: 0.89) and moderate test-retest reliability after 45-60 days (intraclass coefficient: 0.54). Exploratory factor analysis revealed the unidimensionality of the PGSI. As for criterion validity, using the diagnosis of gambling disorder in DSM-5 as a reference standard, the stratum specific likelihood ratios of the PGSI score of 0 = non-problem; 1-2 = low risk; 3-7 = moderate risk; and 8-27 = problem gambling were 0.00; 0.68 (95% confidence interval: 0.21 to 2.22); 8.71 (5.2 to 14.5); and 67.9 (35.6 to 129.5) respectively. CONCLUSIONS We recommend including the PGSI in future prevalence studies of problem gambling in Japan.

Abstract
Individuals who undertake tertiary study outside their home countries ("international students") may be at increased risk of problem gambling behaviour. To inform this issue, we examined gambling behaviour, problem gambling behaviour and reasons for gambling among international students, primarily from Asian countries, attending university in Tasmania, Australia. Online surveys that included established measures of each outcome were completed by these students (n = 382) along with a comparison group of domestic students (n = 1013). While most forms of gambling assessed were less common among international students than among domestic students, rates of problem gambling were higher among international students (2.6%) than among domestic (1.4%) students. Further, whereas rates of problem gambling did not differ by sex among domestic students, problem gambling among international students was confined to males. Hence, rates of problem gambling were markedly elevated in this subgroup (5% of all male international students, 15% of male international students who reported any form of gambling in the past 12 months). International students were more likely than domestic students to report engaging in gambling as a means of regulating their internal states and for a challenge and these and other reasons for gambling were positively correlated with problem gambling behaviour. The findings support the need for population- and campus-based health promotion and early intervention programs targeting international students, male students in particular. Information concerning individuals' reasons for gambling might usefully be included in these programs.

Abstract
BACKGROUND AND AIMS The Problem Gambling Severity Index (PGSI) is one of the most widely used screening tools for problem gambling (PG). However, to date, no empirically validated adaptation of the instrument to Spanish-speaking countries exists. METHODS A sample of 659 sports bettors (Mage = 35.1 years, SD = 10.12, 74.2% males) were recruited through an online research panel. A confirmatory factor analysis (CFA) was performed to confirm its construct validity. The participants were administered the Spanish version of the PGSI, along with the adaptation to Spanish of the DSM-IV PG instrument for convergent validity. RESULTS The CFA of the Spanish PGSI showed satisfactory construct validity. The internal consistency (αordinal = .97) as well as its convergent validity with the DSM-IV scores (r = .77, p < .001) was good. CONCLUSION The Spanish adaptation of the PGSI offers satisfactory validity and reliability properties, and is a good psychometric instrument for exploring the social consequences of PG in Spanish-speaking contexts.

Abstract
Problematic patterns of gambling and their harms are known to have culturally specific expressions. For ethnic Chinese people, patterns of superstitious belief in this community appear to be linked to the elevated rates of gambling-related harms; however, little is known about the mediating psychological mechanisms. To address this issue, we surveyed 333 Chinese gamblers residing internationally and used a mediation analysis to explore how gambling-related cognitive biases, gambling frequency and variety of gambling forms ('scope') mediate the association between beliefs in luck and gambling problems. We found that cognitive biases and scope were significant mediators of this link but that the former is a stronger mediator than the latter. The mediating erroneous beliefs were not specific to any particular type of cognitive bias. These results suggest that Chinese beliefs in luck are expressed as gambling cognitive biases that increase the likelihood of gambling problems, and that biases that promote gambling (and its harms) are best understood within their socio-cultural context.

Abstract
This paper reports on the cross validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS). The CAGI/GPSS was included in a large school based drug use and health survey conducted in 2015. Data from students in grades 9–12 (ages 13–20 years) derived from the (N = 3369 students). The CAGI/GPSS produced an alpha of 0.789. A principle component analysis revealed two eigenvalues greater than one. An oblique rotation revealed these components to represent consequences and over involvement. The CAGI/GPSS indicated that 1% of the students fell into the “red” category indicating a severe problem and an additional 3.3% scored in the “yellow” category indicating low to moderate problems. The CAGI/GPSS was shown to be significantly correlated with gambling frequency (r = 0.36), largest expenditure (r = 0.37), sex (more likely to be male) (r = −0.19), lower school marks (r = −0.07), hazardous drinking, (r = 0.16), problem video game play (r = 0.16), as well as substance abuse. The CAGI/GPSS was cross validated using a shorted version of the short SOGS, r = 0.48. In addition the CAGI/GPSS and short SOGS produced very similar patterns of correlations results. The results support the validity and reliability of the CAGI/GPSS as a measure of gambling problems among adolescents.

Abstract
In October 2008, Iceland experienced the fastest and deepest financial crisis recorded in modern times when all three major banks went bankrupt in less than 2 weeks. The purpose of this follow-up study is to examine potential changes in participation in 12 different gambling types and in problem gambling before (time 1; year 2007) and after (time 2; year 2011) the economic collapse in 2008. The time between the first and second wave of data collection was 3.5 years. In total, 1,531 participants took part in the study, 688 males and 843 females. There was a considerable increase in past year gambling behavior from 2007 to 2011, mostly due to increased participation in lotto (National lotto and Viking lotto) but also in bingo, monthly lotteries (class lotteries with at least monthly draw) and scratch tickets. Only EGMs (electronic gaming machines) participation declined significantly between the two timepoints. Examining past year problematic gambling figures revealed that there were no changes in the prevalence figures between the year 2007 (1.2%) and 2011 (1.1%). Further examination revealed that those who reported financial difficulties due to the recession were more likely to buy lotto- or scratch tickets during the recession than those who were not financially affected by the crisis. These findings remained after controlling for background variables and baseline gambling activity (gambling in 2007). Overall, the findings of the follow-up study suggest that when people are experiencing financial difficulties during economic recessions, the possibility to improve their financial situation by winning large jackpots with low initial stakes becomes more enticing.

Abstract
Objectives The study examined Macau parents’ perceptions of underage children’s gambling involvement, and parents’ attitudes towards help seeking if their children had a gambling problem. The parents’ gambling behavior in the past year was also investigated. Methods This is a parent survey using a self-administered questionnaire. A convenience sample of 311 Macau parents (106 fathers and 205 mothers) with underage children aged 3–17 years was recruited. The response rate is 77.8%. The participants were asked if they had ever approved or taught their underage children to gamble, and how did they award their children when they won in gambling games. The parents were also asked if they had gambled in the previous 12 months, and their gambling behavior was assessed by the Chinese Problem Gambling Severity Index (CPGSI). Results Half of the parents surveyed (52%) did not approve underage gambling but 81% taught their underage children to play different gambling games. Children were awarded with money (55%), praises (17.5%), toys (15%) and food (12.5%) when they won in games. One-fifth (20.6%) were distressed with their children’s gambling problem. Many (68.8%) were willing to seek help to cope with children’s gambling problems. Only 21.2% (n = 66) of the parents reported gambling in the past year. Using the CPGSI, 4.5% of these gamblers could be identified as problem gamblers, and 16.7% were moderate-risk gamblers. Conclusion The study results indicate parent education should be included in prevention of underage gambling.

Abstract
Youth problem gambling is viewed as an emergent public health issue in many countries, and is also an emerging area of public concern in Portugal. However, there is currently no Portuguese instrument that focuses specifically on the measurement of problem gambling among young people. Consequently, the present study aimed to validate the DSM-IV-MR-J for use among Portuguese adolescents and to examine its’ psychometric properties. A cross-cultural adaption of this instrument to the Portuguese language was performed using the translation and back translation method. The final version of the instrument was administered to 753 Portuguese high school and first year college students. The findings revealed an acceptable internal reliability and replicated the one-factor structure of this scale. Based on these findings, the Portuguese DSM-IV-MR-J appears to be a valid and reliable instrument, and provides a much needed psychometric tool for the development of more research on youth gambling in Portugal.

Abstract
Problem gambling and sleep difficulty threaten health. Using the basis of self-regulatory theory, potential mechanisms for these problems were investigated. Fifty-nine treatment-seeking gamblers completed the Pittsburgh Sleep Quality Index (sleep difficulty), the Sleep Hygiene Index (negative sleep habits), the Problem Gambling Severity Index and measures of self-regulatory capacity and arousability with data entered into regression analyses. Results supported the relationship between problem gambling and greater sleep difficulty (β = .18, t = 3.22, p < .01). Self-regulatory capacity mediated the relationship between problem gambling and sleep difficulty (R (2) change = .15, F(2, 57) = 12.14, β = -.45, t = -3.45, p < .001) as well as between problem gambling and negative sleep habits; R (2) change = .17, F(2, 57) = 13.57, β = -.28, t = -3.76, p < .001. Arousability predicted sleep difficulty (β = .15, t = 3.07, p < .01) and negative sleep habits (β = .40, t = 5.40, p < .01) but showed no relationship with problem gambling (r = .09, ns). Self-regulatory capacity represents an important mediator of the relationship between problem gambling and sleep-related behaviour and if targeted could reduce behavioural threats to health.

Abstract
Regulatory policies for responsible gambling practices in Asia are constantly evolving as the gambling industry and technological landscape change over time. Malaysia makes an interesting case study for a commentary on gambling participation and policies, as this country has a unique dual justice system with religious and ethnic diversity that may impact on the way in which gambling activities are regulated. This regulatory ecosystem has important consequences on behaviour change, treatment approaches and recovery processes involved in gambling disorder. This commentary will discuss evidence for Malaysian gambling antecedents, public policy and socioeconomic impacts of gambling, possible costs and benefits of gambling legalization, and issues pertinent to regulating gambling activities in Malaysia.

Abstract
In October 2008 all three major banks in Iceland went bankrupt with serious consequences for Icelandic society. The national currency lost more than half of its value and there was a sharp increase in household debts and prices for domestic goods. Very little is known about the potential effects of economic recessions on gambling participation and problem gambling. This study reports on the results of three national prevalence studies conducted before and after the economic collapse in Iceland. The same methodology and measures were used in all three studies to ensure their comparability and the studies included in total N = 8.249 participants. There was an increase in past year gambling participation which extended across most gambling types. Only participation on EGMs declined significantly after the economic collapse. Past year prevalence of problematic gambling increased but further examination revealed that this increase is most probably explained by an increase in card and internet gambling among young men. Moreover, those who experienced financial difficulties due to the economic recession were 52% more likely to have bought a lottery ticket during the recession compared to those who were not affected financially. Overall, the results indicate that serious national economic recessions have differential effects on gambling behavior.

Abstract
BACKGROUND AND AIMS The aim of the present study was to test the impulsivities and compulsivities of behavioral addictions, including Internet gaming disorder (IGD) and gambling disorder (GD), by directly comparing them with alcohol use disorder (AUD) and a healthy control (HC) group. METHODS We enrolled male patients who were diagnosed with IGD, GD or AUD, with 15 patients per group, as well as 15 HCs. Trait impulsivity was measured using the Barratt Impulsiveness Scale version 11 (BIS-11). The stop-signal test (SST) from the Cambridge Neuropsychological Test Automated Battery (CANTAB) was used to assess the patients’ abilities to inhibit prepotent responses. Compulsivity was measured using the intra–extra dimensional set shift (IED) test from the CANTAB. The Trail Making Test (TMT) was also used in this study. RESULTS The IGD and AUD groups scored significantly higher on the BIS-11 as a whole than did the HC group (p = 0.001 and p = 0.001, respectively). The IGD and AUD groups also scored significantly higher on the BIS-11 as a whole than did the GD group (p = 0.006 and p = 0.001, respectively). In addition, the GDgroup made significantly more errors (p = 0.017 and p = 0.022, respectively) and more individuals failed to achieve criterion on the IED test compared with the IGD and HC groups (p = 0.018 and p = 0.017, respectively). Discussion: These findings may aid in the understanding of not only the differences in categorical aspects between individuals with IGD and GD but also in impulsivity–compulsivity dimensional domains. CONCLUSION Additional studies are needed to elucidate the neurocognitive characteristics of behavioral addictive disorders in terms of impulsivity and compulsivity.

Abstract
We investigate the question whether problem gambling (PG) in a recent South African sample, as measured by the Problem Gambling Severity Index (PGSI), is dimensional or categorical. We use two taxometric procedures, Mean Above Minus Below A Cut (MAMBAC) and Maxim Covariance (MAXCOV), to investigate the taxonic structure of PG as constructed by the PGSI. Data are from the 2010 South African National Urban Prevalence Study of Gambling Behavior. A representative sample of the urban adult population in South Africa (N = 3,000). Responses are to the 9 item PGSI. MAMBAC provided positive but modest evidence that PG as measured by the PGSI was taxonic. MAXCOV pointed more strongly to the same conclusion. These analyses also provide evidence that a PGSI cutoff score of 10 rather than the standard 8 may be called for. PG as constructed by the PGSI may best be thought of as categorical, but further studies with more theory based measurements are needed to determine whether this holds in a wider range of samples and for other screens. A higher cutoff score may be called for on the PGSI when it is used for research purposes to avoid false positives.

Abstract
The aim of this study was to adapt to the Italian context a very commonly used international instrument to detect problem gambling, the canadian problem gambling index (CPGI), and assess its psychometric properties. Cross-cultural adaptation of CPGI was performed in several steps and the questionnaire was administered as a survey among Italian general population (n = 5,292). Cronbach's alpha reliability coefficient was 0.87 and can be considered to be highly reliable. Construct validity was assessed first by means of a principal component analysis and then by means of confirmatory factor analysis, showing that only one factor, problem gambling, was extracted from the CPGI questionnaire (an eigenvalues of 4,684 with percentage of variance 52 %). As far as convergent validity is concerned, CPGI was compared with Lie/Bet questionnaire, a two-item screening tool for detecting problem gamblers, and with both depression and stress scales. A short form DSM-IV CIDI questionnaire was used for depression and VRS scale, a rating scale, was used for rapid stress evaluation. A strong convergent validity with these instruments was found and these findings are consistent with past research on problem gambling, where another way to confirm the validity is to determine the extent to which it correlates with other qualities or measures known to be directly related to problem gambling. In sum, despite the lack of a direct comparison with a classic gold-standard such as DSM-IV, the Italian version of CPGI exhibits good psychometric properties and can be used among the Italian general population to identify at-risk problem gamblers.

Abstract
The Problem Gambling Severity Index, the scored module of the Canadian Problem Gambling Index, is a population-based survey instrument that is becoming the preferred epidemiological tool for estimating the prevalence of disordered gambling. While some validation evidence for the Problem Gambling Severity Index is available, very little is known about its psychometric characteristics in developing countries or in countries the populations of which are not highly Westernised. The aim of this study was to investigate the validity of the Problem Gambling Severity Index with a specific focus on its criterion-related and construct (concurrent) validity in a community sample of gamblers in South Africa ( n = 127). To this end, the Problem Gambling Severity Index was administered alongside the Diagnostic Interview for Gambling Severity and measures known to associate with gambling severity (impulsivity, current debt, social problems, financial loss, race, sex). Results showed that the Problem Gambling Severity Index was predictive of Diagnostic Interview for Gambling Severity diagnosis from both a categorical and dimensional point of view and demonstrated high discrimination accuracy for subjects with problem gambling. Analysis of sensitivity and specificity at different cut-points suggests that a slightly lower Problem Gambling Severity Index score may be used as a screening cut-off for problem gambling among South African gamblers. The Problem Gambling Severity Index also showed significant correlations with the Barratt Impulsiveness Scale, a widely known measure of impulsivity, and with some of the predicted behavioural variables of interest (gambling activities, money lost to gambling, current debt, interpersonal conflict). This article therefore demonstrates initial criterion and concurrent validity for the Problem Gambling Severity Index for use in South African samples.

Abstract
The majority of prevention and intervention research in problem gambling (PG) has focused on identifying negative risk factors. However, not all at-risk individuals go on to develop anticipated disorders and many thrive in spite of them. In healthcare settings, PG and other disorders are typically conceptualized from the biomedical perspective that frame disorders as something negative residing within the individual and reduction in negativity is seen as success. Indeed, this problem-focused conceptualization may be adequate in many cases as reducing PG behaviour is undoubtedly an important outcome, but the focus on negativity alone is too narrow to capture the complexity of human behaviour. Hence, this study attempts to bridge the gap in literature by providing an evaluation of the predictive ability of the positive dispositions on problem gambling severity, gambling-related cognitions, and gambling urges. The positive psychological dispositions examined were curiosity, gratitude, hope, personal growth initiative, and mindfulness. Participants consisted of 801 Taiwanese Chinese students and community individuals (Mean age = 25.36 years). Higher levels of gratitude and hope have been found to predict lower PG, gambling-related cognitions, or gambling urges. Meanwhile, higher mindfulness predicted lower PG, but only among Chinese males. However, lower personal growth initiative predicted lower PG, gambling-related cognitions, and gambling urges. These analyses have small to medium effect sizes with significant predictions. Findings of this study have essential implications in understanding and treating Chinese problem gamblers. These positive dispositions should be addressed by mental health professionals in preventative and treatment programs among Chinese individuals. Further implications and suggestions for future research are discussed.

Abstract
Increases in the availability of gambling heighten the need for a short screening measure of problem gambling. The Problem Gambling Severity Index (PGSI) is a brief measure that allows for the assessment of characteristics of gambling behavior and severity and its consequences. The authors evaluate the psychometric properties of the PGSI using item response theory methods in a representative sample of the urban adult population in South Africa (N = 3,000). The PGSI items were evaluated for differential item functioning (DIF) due to language translation. DIF was not detected. The PGSI was found to be unidimensional, and use of the nominal categories model provided additional information at higher values of the underlying construct relative to a simpler binary model. This study contributes to the growing literature supporting the PGSI as the screen of choice for assessing gambling problems in the general population.
