Fulltext A systematic review of gambling-related findings from the National Epidemiologic Survey on Alcohol and Related Conditions

Loo JMY, Kraus SW, Potenza MN

J Behav Addict, 2019 Dec 01;8(4):625-648.
PMID: 31830810 DOI: 10.1556/2006.8.2019.64

BACKGROUND AND AIMS: This systematic review analyzes and summarizes gambling-related findings from the nationally representative US National Epidemiological Survey on Alcohol and Related Conditions (NESARC) data.
METHODS: Systematic literature searches in accordance with PRISMA guidelines found 51 eligible studies that met inclusion criteria. Eight studies utilized both Waves 1 and 2 NESARC data, and selection of sample sizes varied from 185 to 43,093 individuals, consistent with specified research objectives of each study.
RESULTS: The prevalence of lifetime pathological gambling was 0.42% (0.64% among men, 0.23% among women), while past-year prevalence was 0.16%. Pathological gambling rates were generally higher in populations with substance-use disorders and other psychiatric diagnoses. Rates of adverse childhood experiences and suicidal attempts were higher among individuals with problem or pathological gambling. Early-onset gamblers were more likely to be male, be never married, have incomes below $70,000, belong to younger cohorts and have Cluster B personality disorders, but less likely to be diagnosed with mood disorders. While pathological gambling was related to obesity, increased stress, and poorer physical health among general age groups, recreational gambling was linked with improved physical and mental functioning in older adults.
CONCLUSIONS: The NESARC has provided important information on the correlates of pathological gambling and subdiagnostic patterns of gambling behaviors. Additional studies should examine these relationships in the current gambling environment and longitudinally with aims of implementing policies to improve the public health.

Fulltext Understanding the psychology of mobile gambling: A behavioural synthesis

James RJE, O'Malley C, Tunney RJ

Br J Psychol, 2017 Aug;108(3):608-625.
PMID: 27753063 DOI: 10.1111/bjop.12226

This manuscript reviews the extant literature on key issues related to mobile gambling and considers whether the potential risks of harm emerging from this platform are driven by pre-existing comorbidities or by psychological processes unique to mobile gambling. We propose an account based on associative learning that suggests this form of gambling is likely to show distinctive features compared with other gambling technologies. Smartphones are a rapidly growing platform on which individuals can gamble using specifically designed applications, adapted websites or text messaging. This review considers how mobile phone use interacts with psychological processes relevant to gambling, the games users are likely to play on smartphones, and the interactions afforded by smartphones. Our interpretation of the evidence is that the schedules of reinforcement found in gambling interact with the ways in which people tend to use smartphones that may expedite the acquisition of maladaptive learned behaviours such as problem gambling. This account is consistent with existing theories and frameworks of problem gambling and has relevance to other forms of mobile phone use.

Fulltext Feedback-related potentials in a gambling task with randomised reward

Mushtaq F, Guillen PP, Wilkie RM, Mon-Williams MA, Schaefer A

Data Brief, 2016 Mar;6:378-85.
PMID: 26862585 DOI: 10.1016/j.dib.2015.11.060

Event-related potentials (ERPs) time-locked to decision outcomes are reported. Participants engaged in a gambling task (see [1] for details) in which they decided between a risky and a safe option (presented as different coloured shapes) on each trial (416 in total). Each decision was associated with (fully randomised) feedback about the reward outcome (Win/Loss) and its magnitude (varying as a function of decision response; 5-9 points for Risky decisions and 1-4 points for Safe decisions). Here, we show data demonstrating: (a) the influence of Win feedback in the preceding outcome (Outcome t-1) on activity related to the current outcome (Outcome t ); (b) difference wave analysis for outcome expectancy- separating Expected Outcomes (consecutive Loss trials subtracted from consecutive reward) from Unexpected Outcomes (subtracting Loss t-1Win t trials from Win t-1Loss t trials); (c) difference waves separating Switch and Stay responses for Outcome Expectancy; (d) the effect of magnitude induced by decisions (Risk t vs. Safe t ) on Outcome Expectancy; and finally, (e) expectations reflected by response switch direction (Risk to Safe responses vs. Safe to Risk t ) on the FRN at Outcome t .

The Impact of Addictive Behaviors on Adolescents Psychological Well-Being: The Mediating Effect of Perceived Peer Support

Khasmohammadi M, Ghazizadeh Ehsaei S, Vanderplasschen W, Dortaj F, Farahbakhsh K, Keshavarz Afshar H, et al.

J Genet Psychol, 2019 12 30;181(2-3):39-53.
PMID: 31886741 DOI: 10.1080/00221325.2019.1700896

Studies exploring excessive Internet use and gambling are rapidly expanding concerns regarding its impact on mental health, especially in young people due to the increased prevalence of Internet and gambling addictions. Research suggests that perceived peer support plays a significant role in adolescents' psychological well-being. However, no empirical study has dealt with the mediating effect of perceived peer support on the relationship between Internet and gambling addictions and psychological well-being. Thus, the present study aimed to examine whether perceived peer support mediates the relation between Internet and gambling addictions and psychological well-being of adolescents. A sample of 347 Iranian adolescents aged 14 to 18 (Mean age 16.14, 50.4% male) who were studying in Kuala Lumpur, Malaysia participated in this study. Subjective Vitality Scale (SVS), Compulsive Internet Use Scale (CIUS), Six-item Social Support Questionnaire (SSQ6), and The South Oaks Gambling Screen (SOGS) were used to collect data. Mediation analyses showed a significant indirect effect of compulsive Internet use and problem gambling on psychological well-being through perceived peer support. The total effects of compulsive Internet use and problem gambling on psychological well-being were negative. This study implies the significance of strengthening the knowledge about the impact of peer relationships among adolescents.

Fulltext Why are Some Games More Addictive than Others: The Effects of Timing and Payoff on Perseverance in a Slot Machine Game

James RJ, O'Malley C, Tunney RJ

Front Psychol, 2016;7:46.
PMID: 26869955 DOI: 10.3389/fpsyg.2016.00046

Manipulating different behavioral characteristics of gambling games can potentially affect the extent to which individuals persevere at gambling, and their transition to problematic behaviors. This has potential impact for mobile gambling technologies and responsible gambling interventions. Two laboratory models pertinent to this are the partial reinforcement extinction effect (PREE) and the trial spacing effect. Both of these might speed up or delay the acquisition and extinction of conditioned behavior. We report an experiment that manipulated the rate of reinforcement and inter trial interval (ITI) on a simulated slot machine where participants were given the choice between gambling and skipping on each trial, before perseverative gambling was measured in extinction, followed by measurements of the illusion of control, depression and impulsivity. We hypothesized that longer ITI's in conjunction with the low rates of reinforcement observed in gambling would lead to greater perseverance. We further hypothesized, given that timing is known to be important in displaying illusory control and potentially in persevering in gambling, that prior exposure to longer intervals might affect illusions of control. An interaction between ITI and rate of reinforcement was observed, as low reinforced gamblers with a long ITI gambled for longer. Respondents also displayed extinction and a PREE. Gamblers exposed to a higher rate of reinforcement gambled for longer in acquisition. Impulsivity was associated with extended perseverance in extinction, and more depressed gamblers in the high reinforcement short ITI group persevered for longer. Performance in the contingency judgment failed to support the second hypothesis: the only significant contrast observed was that participants became better calibrated as the task progressed.

Treatment of Gambling Problems in Asia: Comprehensive Review and Implications for Asian Problem Gamblers

Raylu N, Loo J, Oei TPS

J Cogn Psychother, 2013;27(3):297-322.
PMID: 32759146 DOI: 10.1891/0889-8391.27.3.297

Much research has been conducted in the treatment of gambling problems. However, very little is reported specifically on treating Asian problem gamblers. Thus, this article reviewed the general problem gambling treatment literature as well as the limited Asian problem gambling treatment literature to provide a discussion of interventions that can be used with Asian problem gamblers. The general literature showed that behavioral, cognitive, and combined cognitive behavioral treatments (CBT) have the most treatment outcome literature and appear to be the most effective in treating gambling problems. Although, pharmacotherapy also looks promising, it may be more suitable for problem gamblers with comorbid mood problems or impulsivity. Research on other forms of treatments also exists (e.g., 12-step and psychodynamic treatment approaches) but are not as robust. Only three studies have reported on the effectiveness of treatment with Asian problem gamblers. The first study is case study. The second study presents data from a treatment program for Asian problem gambling and the last one presents preliminary findings of a telephone delivered treatment program with eight Asian American gamblers. These studies support the general treatment literature in showing that CBT and pharmacotherapy have a role to play in treating Asian problem gamblers. Based on the general and Asian problem gambling treatment literature, a discussion of treatment of Asian problem gamblers is provided including the use of CBT and other forms of treatment, issues to address in treatment, and variables that can assist treatment.

Reasons on the similarity of objections with regards to gambling and speculation in Islamic finance and conventional finance

Kunhibava S

J Gambl Stud, 2011 Mar;27(1):1-13.
PMID: 20514512 DOI: 10.1007/s10899-010-9201-5

Gambling and speculation which leads to zero-sum outcomes are prohibited in Islamic finance and condemned in conventional finance. This article explores the reasons for the similarity of objections towards gambling and speculation. Three probable reasons are explored namely the concept of stewardship in conventional thought and the concept of khalifa in Islam, Christianity and morality's influence on conventional law and finance and the concept of ethics of sacrifice and ethics of tolerance.

Testing the Validity of a Cognitive Behavioral Model for Gambling Behavior

Raylu N, Oei TP, Loo JM, Tsai JS

J Gambl Stud, 2016 Jun;32(2):773-88.
PMID: 26363793 DOI: 10.1007/s10899-015-9567-5

Currently, cognitive behavioral therapies appear to be one of the most studied treatments for gambling problems and studies show it is effective in treating gambling problems. However, cognitive behavior models have not been widely tested using statistical means. Thus, the aim of this study was to test the validity of the pathways postulated in the cognitive behavioral theory of gambling behavior using structural equation modeling (AMOS 20). Several questionnaires assessing a range of gambling specific variables (e.g., gambling urges, cognitions and behaviors) and gambling correlates (e.g., psychological states, and coping styles) were distributed to 969 participants from the community. Results showed that negative psychological states (i.e., depression, anxiety and stress) only directly predicted gambling behavior, whereas gambling urges predicted gambling behavior directly as well as indirectly via gambling cognitions. Avoidance coping predicted gambling behavior only indirectly via gambling cognitions. Negative psychological states were significantly related to gambling cognitions as well as avoidance coping. In addition, significant gender differences were also found. The results provided confirmation for the validity of the pathways postulated in the cognitive behavioral theory of gambling behavior. It also highlighted the importance of gender differences in conceptualizing gambling behavior.

Gambling, Drinking and Quality of Life: Evidence from Macao and Australia

Loo JM, Shi Y, Pu X

J Gambl Stud, 2016 Jun;32(2):391-407.
PMID: 26337063 DOI: 10.1007/s10899-015-9569-3

The investigation of the interface between psychological constructs, compulsive consumption of alcohol and pathological gambling is an important avenue for development of future initiatives in social marketing or prevention programs. This cross-cultural study attempts to bridge the gap in literature by providing an evaluation of the predictive ability of psychological variables such as gambling urge, gambling-related erroneous cognitions and comorbid alcohol consumption on pathological gambling behaviour and its impact on overall quality of life indicators. Participants consist of 445 Macao and Australian young adults (Mean age = 23 years). Results indicate that probable pathological gamblers as compared with non-gamblers reported significantly lower quality of life in all domains-physical health, psychological well-being, social relationships and environment. Adults who drank more alcohol and have stronger erroneous cognitions evidenced higher pathological gambling behavior. Our research model fits both cohorts and interestingly, erroneous gambling-related cognitions serve as a full mediator for the predictive relationship between gambling urge and pathological gambling in the Macao sample, but serve as a partial mediator in the Australian sample. Targeting erroneous cognitions in future social marketing or preventive campaigns should demonstrate to be an important strategy in reducing the effects of urge to gamble among at-risk individuals. Further implications for the industry, marketing and governmental strategies are discussed.

Understanding the Mechanisms Underlying Gambling Behaviour and Sleep

Loft MH, Loo JM

J Gambl Stud, 2015 Dec;31(4):1273-86.
PMID: 25381635 DOI: 10.1007/s10899-014-9514-x

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.

Fulltext Gratitude, hope, mindfulness and personal-growth initiative: buffers or risk factors for problem gambling?

Loo JM, Tsai JS, Raylu N, Oei TP

PLoS One, 2014;9(2):e83889.
PMID: 24523854 DOI: 10.1371/journal.pone.0083889

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.

Loss of Control as a Discriminating Factor Between Different Latent Classes of Disordered Gambling Severity

James RJ, O'Malley C, Tunney RJ

J Gambl Stud, 2016 Dec;32(4):1155-1173.
PMID: 26892198

Analyses of disordered gambling assessment data have indicated that commonly used screens appear to measure latent categories. This stands in contrast to the oft-held assumption that problem gambling is at the extreme of a continuum. To explore this further, we report a series of latent class analyses of a number of prevalent problem gambling assessments (PGSI, SOGS, DSM-IV Pathological Gambling based assessments) in nationally representative British surveys between 1999 and 2012, analysing data from nearly fifty thousand individuals. The analyses converged on a three class model in which the classes differed by problem gambling severity. This identified an initial class of gamblers showing minimal problems, a additional class predominantly endorsing indicators of preoccupation and loss chasing, and a third endorsing a range of disordered gambling criteria. However, there was considerable evidence to suggest that classes of intermediate and high severity disordered gamblers differed systematically in their responses to items related to loss of control, and not simply on the most 'difficult' items. It appeared that these differences were similar between assessments. An important exception to this was one set of DSM-IV criteria based analyses using a specific cutoff, which was also used in an analysis that identified an increase in UK problem gambling prevalence between 2007 and 2010. The results suggest that disordered gambling has a mixed latent structure, and that present assessments of problem gambling appear to converge on a broadly similar construct.

Brain activity elicited by reward and reward omission in individuals with psychopathic traits: An ERP study

Salim MA, van der Veen FM, van Dongen JD, Franken IH

Biol Psychol, 2015 Sep;110:50-8.
PMID: 26188154 DOI: 10.1016/j.biopsycho.2015.07.001

Psychopathy has been associated with behavioral adaptation deficits, which might be associated with problems in feedback and reward processing. In the present study, we examined the relation between psychopathic traits and reward processing in a passive gambling task. A total of 39 male participants who scored high (HP) and 39 male participants who scored low (LP) on the Triarchic Psychopathy Measure (TriPM), total score were tested. Feedback-related Event-Related Potentials (ERPs; i.e., P2, FRN, and P3) on predicted and unpredicted rewards and reward omissions were compared between both groups. It was found that in HP individuals, the P2 was enhanced for predicted rewards and reward omissions, but not for unpredicted stimuli. Moreover, HP individuals as compared to the LP individuals demonstrated a generally reduced P3 amplitude. The FRN amplitude, however, did not differ between the two groups. In addition, HP individuals showed enhanced reward sensitivity on the self-report level. Taken together, these findings suggest that HP individuals show enhanced sensitivity to early and reduced sensitivity to later markers of processing reinforcement learning signals, which points in the direction of compromised behavioral adaptation.

Gambling Risk Amongst Adolescents: Evidence from a School-Based Survey in the Malaysian Setting

Sheela PS, Choo WY, Goh LY, Tan CP

J Gambl Stud, 2016 Jun;32(2):643-59.
PMID: 26499201 DOI: 10.1007/s10899-015-9577-3

There has been emerging evidence regarding gambling experiences of young people in Asia recently, but to date, none in Malaysia. This study aimed to estimate the prevalence of gambling, and to identify individual, familial and high-risk behaviours factors among Malaysian adolescents. A cross-sectional study was conducted over 4 months at randomly selected secondary schools in Seremban in Negeri Sembilan state. A total of 2265 self-administered, anonymous questionnaires were distributed to the students. The students completed the questionnaire consisting of sociodemographic and family background, gambling behaviours, high risk behaviours and mental health questions. Approximately 29.6 % (95 % CI 27.7-31.5) of respondents reported participating in some forms of gambling activities in the previous 12 months. Among these, 3.6 % (95 % CI 2.8-4.3) of them were problem gamblers. Parental gambling was the strongest correlate with adolescent gambling behaviour. Signification association was found between gambling behaviour and gender (being males), but interestingly, not with ethnicity. Adolescents who reported engaging in high risk behaviours (such as smoking, alcohol consumption, involvement in physical fights, illegal vehicular racing) were also more likely to gamble. Gambling is not an uncommon phenomenon amongst Malaysian adolescents. Public awareness campaign, health education to targeted groups, revision of existing laws, and screening at primary care level should be implemented to address the issue of gambling among adolescents. This study also highlights the need to examine the national scope of the problem in Malaysia.

Fulltext High carbonated soft drink consumption is associated with externalizing but not internalizing behaviours among university students in five ASEAN states

Pengpid S, Peltzer K

Psychol Res Behav Manag, 2019;12:585-592.
PMID: 31534377 DOI: 10.2147/PRBM.S209611

Background: The investigation aimed to estimate the association between carbonated soft drink consumption frequency and externalizing and internalizing behaviour among university students in five ASEAN counties.
Methods: A cross-sectional survey included 3353 university students from Indonesia, Malaysia, Myanmar, Thailand and Vietnam, median age 20 years (interquartile range 3 years).
Results: In all five ASEAN countries, the study found a prevalence no soft drink consumption in the past 30 days of 20.3%, less than one time a day 44.7%, once a day 25.4% and two or more times a day 9.6%. In the adjusted logistic regression analysis, higher frequency of soft drink consumption (one and/or two or more times a day) was associated with externalizing behaviour (in physical fight, injury, current tobacco use, problem drinking, drug use, pathological internet use and gambling behaviour), and higher frequency of soft drink consumption (two or more times a day) was associated with depression in females, but no association was found for the general student population in relation to internalizing behaviour (depression, posttraumatic stress disorder, suicidal ideation, suicide plan, suicide attempt and sleeping problem).
Conclusions: Findings suggest that carbonated soft drink consumption is associated with a number of externalizing but not internalizing health risk behaviours.
