Predicting gambling behaviour and problems from implicit and explicit positive gambling outcome expectancies in regular gamblers

Outcome expectancies are the positive or negative effects that individuals anticipate may occur from engaging in a given behaviour. Although explicit outcome expectancies have been found to play an important role in gambling, research has yet to assess the role of implicit outcome expectancies in gambling. In two studies, we investigated whether implicit and explicit positive gambling outcome expectancies were independent predictors of gambling behaviour (i.e. amount of time spent and money risked gambling; Study 1) and problem gambling severity (Study 2). In both studies, implicit positive gambling outcome expectancies were assessed by having regular gamblers (N = 58 in Study 1; N = 96 in Study 2) complete a gambling outcome expectancy reaction time (RT) task. A self-report measure of positive gambling outcome expectancies was used to assess participants' explicit positive gambling outcome expectancies. Both the RT task and self-report measure of positive gambling outcome expectancies significantly contributed unique as well as shared variance in the prediction of self-reported gambling behaviour (Study 1) and problem gambling severity (Study 2). Findings from the current research point to the importance of using both direct and indirect assessment modes when examining the role of outcome expectancies in gambling.     

Examining the effects of gambling-relevant cues on gambling outcome expectancies

There is a consensus in the addictions literature that exposure to addiction-relevant cues can precipitate a desire to engage, or actual engagement, in the addictive behaviour. Previous work has shown that exposure to gambling-relevant cues activates gamblers’ positive gambling outcome expectancies (i.e. their beliefs about the positive results of gambling). The current study examined the effects of a new, arguably more ecologically valid cue manipulation (i.e. exposure to a gambling lab environment vs. sterile lab environment) on 61 regular gamblers’ explicit and implicit gambling outcome expectancies. The authors first tested the internal consistency of their implicit reaction time measure of gambling outcome expectancies, the Affective Priming Task. Split-half reliabilities were satisfactory to high (.72 to .88), highlighting an advantage of this task over other characteristically unreliable implicit cognitive measures. Unexpectedly, no predicted between-lab condition differences emerged on most measures of interest, suggesting that peripheral environmental cues that are not the focus of deliberate attentional allocation may not activate positive outcome expectancies. However, there was some evidence that implicit negative gambling outcome expectancies were activated in the gambling lab environment. This latter finding holds clinical relevance as it suggests that presenting peripheral gambling-related cues while treating problem gamblers may facilitate processing of the negative consequences of gambling.     

Gender Differences in Characteristics of Chinese Treatment-Seeking Problem Gamblers

A total of 952 (841 men and 111 women) Chinese treatment-seeking problem gamblers completed self-report assessment forms. Female in contrast to male gamblers were more likely to be older, married, less educated, and without employment. Female gamblers also started gambling at an older age, had a shorter gambling history, preferred casino and mahjong gambling, and reported more somatic complaints and suicidal thoughts. Male and female gamblers accumulated similar amount of gambling debt and reported an average of 12 gambling-related problems on the Chinese version of the South Oaks Gambling Screen [Lesieur and Blume (Am J Psychiatry 144:1184–1188, 1987)]. Both groups were similarly troubled by their indebtedness, inability to control gambling, and gambling-related interpersonal problems. However, female gamblers had fewer means to pay their gambling debt. Given that significant gender-related differences were observed in Chinese problem gamblers, prevention and treatment services should attend to specific needs of male and female gamblers.     

Urge to Gamble in Problem Gamblers Exposed to a Casino Environment

Cue-reactivity has received increased attention in addiction research, though not for gambling in particular. We examined cue reactivity in 18 problem gamblers by accompanying them to a gaming casino and measuring their subjective urge to gamble over a 1-h period. Half of the sample was additionally exposed to a gambling-specific negative mood induction (NMI) manipulation via guided imagery. Overall, about two-thirds of the sample reported moderate to high-gambling urges during the casino exposure. Additionally, the NMI reduced cue-reactivity. Finally, gambling urges in both groups decreased over the course of the exposure sessions. These findings suggest that a majority of problem gamblers experience the urge to gamble when exposed to gambling cues and that the intensity of these urges decrease with time, especially in the presence of a gambling-relevant NMI. Cue exposure should be studied further as a potential tool in the treatment of problem gambling.     

Impact of a Casino Opening on Gambling Behaviors of People Engaged in Methadone Maintenance

This study examined gambling behavior in the context of a newly opening casino, comparing disordered gamblers to non-disordered gamblers, in a population of individuals involved in methadone maintenance treatment. Disordered gamblers (N = 50) and non-disordered gamblers (N = 50) were surveyed before and after the opening of a new casino on gambling behaviors, substance use, and psychological symptoms. No statistically significant changes in gambling behaviors were observed for disordered gamblers or non-disordered gamblers across time points; however, non-disordered gamblers demonstrated non-significant increases in horse and dog race betting, electronic games, and casino table games. As expected, disordered gamblers were found to spend significantly more money on electronic games and casino table games (p < 0.05) and demonstrated higher rates of drug use and impulsivity than non-disordered gamblers. The introduction of a new casino did not appear to have a major impact on gambling behaviors of individuals attending methadone maintenance treatment, though the non-significant increases in gambling among non-disordered gamblers may indicate that this population is preferentially impacted by the opening of a new casino. Future investigation into the longer term effects of opening a new casino on this population may be warranted.     

Cue-Reactive Rationality,Visual Imagery and Volitional Control Predict Cue-Reactive Urge to Gamble in Poker-Machine Gamblers

Poker-machine gamblers have been demonstrated to report increases in the urge to gamble following exposure to salient gambling cues. However, the processes which contribute to this urge to gamble remain to be understood. The present study aimed to investigate whether changes in the conscious experience of visual imagery, rationality and volitional control (over one’s thoughts, images and attention) predicted changes in the urge to gamble following exposure to a gambling cue. Thirty-one regular poker-machine gamblers who reported at least low levels of problem gambling on the Problem Gambling Severity Index (PGSI), were recruited to complete an online cue-reactivity experiment. Participants completed the PGSI, the visual imagery, rationality and volitional control subscales of the Phenomenology of Consciousness Inventory (PCI), and a visual analogue scale (VAS) assessing urge to gamble. Participants completed the PCI subscales and VAS at baseline, following a neutral video cue and following a gambling video cue. Urge to gamble was found to significantly increase from neutral cue to gambling cue (while controlling for baseline urge) and this increase was predicted by PGSI score. After accounting for the effects of problem-gambling severity, cue-reactive visual imagery, rationality and volitional control significantly improved the prediction of cue-reactive urge to gamble. The small sample size and limited participant characteristic data restricts the generalizability of the findings. Nevertheless, this is the first study to demonstrate that changes in the subjective experience of visual imagery, volitional control and rationality predict changes in the urge to gamble from neutral to gambling cue. The results suggest that visual imagery, rationality and volitional control may play an important role in the experience of the urge to gamble in poker-machine gamblers.     

Games and Gambling Involvement Among Casino Patrons

A growing literature is addressing the nature of the relationships among gambling activity, gambling involvement, and gambling-related problems. This research suggests that among the general population, compared to playing any specific game, gambling involvement is a better predictor of gambling-related problems. To date, researchers have not examined these relationships among casino patrons, a population that differs from the general population in a variety of important ways. A survey of 1160 casino patrons at two Las Vegas resort casinos allowed us to determine relationships between the games that patrons played during the 12 months before their casino visit, the games that patrons played during their casino visit, and patrons’ self-perceived history of gambling-related problems. Results indicate that playing specific gambling games onsite predicted (i.e., statistically significant odds ratios ranging from .5 to 4.51) self-perceived gambling-related problems. However, after controlling for involvement, operationally defined as the number of games played during the current casino visit and self-reported gambling frequency during the past 12 months, the relationships between games and gambling-related problems disappeared or were attenuated (i.e., odds ratios no longer statistically significant). These results extend the burgeoning literature related to gambling involvement and its relationship to gambling-related problems.     

Characteristics of Older Adult Problem Gamblers Calling a Gambling Helpline

Background Few investigations have characterized groups of older adults with gambling problems, and published reports are currently limited by small samples of older adult problem gamblers. Gambling helplines represent a widespread mechanism for assisting problem gamblers to move into treatment settings. Given data from older adult problem gamblers in treatment, we hypothesized that older as compared with younger adult problem gamblers calling a gambling helpline would be less likely to report gambling-related problems.Design and methods Logistic regression analyses were performed on data obtained from January 1, 2000 to December 31, 2001, inclusive, from callers with gambling problems (N = 1,084) contacting the Connecticut Council on Problem Gambling Helpline.Results Of the 1,018 phone calls used in the logistic regression analyses, 168 (16.5%) were from older adults and 850 (83.5%) from younger adults. Age-related differences were observed in demographic features, types and patterns of gambling reported as problematic, gambling-related problems and psychiatric symptoms, substance use problems, patterns of indebtedness, and family histories of addictive disorders. Older as compared with younger adult problem gamblers were more likely to report having lower incomes, longer durations of gambling, fewer types of problematic gambling, and problems with casino slot machine gambling and less likely to report gambling-related anxiety, family problems, illegal behaviors and arrests, drug problems, indebtedness to bookies or acquaintances, family histories of drug abuse, and problems with casino table gambling.Conclusions Older as compared with younger adult problem gamblers calling a gambling helpline differ on many clinically relevant features. The findings suggest the need for improved and unique prevention and treatment strategies for older adults with gambling problems.     

Cue Reactivity in Active Pathological,Abstinent Pathological,and Regular Gamblers

Twenty-one treatment-seeking pathological gamblers, 21 pathological gamblers in recovery, and 21 recreational gamblers watched two video-taped exciting gambling scenarios and an exciting roller-coaster control scenario while their arousal (heart rate and subjective excitement) and urge to gamble were being measured. The gamblers did not differ significantly in cue-elicited heart rate elevations or excitement. However, the active pathological gamblers reported significantly greater urges to gamble across all cues compared to the abstinent pathological gamblers and, with marginal significance (p = 0.06), also compared to the social gamblers. Further exploration of these findings revealed that active pathological gamblers experience urges to gamble in response to exciting situations, whether or not they are gambling related, whereas abstinent and social gamblers only report urges to an exciting gambling-related cue. This suggests that for pathological gamblers excitement itself, irrespective of its source, may become a conditioned stimulus capable of triggering gambling behavior. Implications for treatment and future research are discussed.     

Predicting Gambling Problems from Gambling Outcome Expectancies in College Student-Athletes

While previous research has suggested the potential importance of gambling outcome expectancies in determining gambling behaviour among adolescents, the predictive ability of gambling outcome expectancies has not yet been clearly delineated for college-aged youth. The current study aims to explore the relationships between gender and outcome expectancies in the prediction of gambling severity among college student-athletes. Data from the National Collegiate Athletic Association (NCAA) study assessing gambling behaviours and problems among U.S. college student-athletes were utilized. Complete data was available for 7,517 student-athletes. As expected, male college student-athletes reported more gambling participation as well as greater gambling problems than their female counterparts. Findings showed positive relationships between the outcome expectancies of financial gain, and negative emotional impacts and gambling problems. That is, those who endorsed more items on the outcome expectancy scales for financial gain and negative emotional impacts also tended to endorse more gambling-related problems. Findings also showed a negative relationship between outcome expectancies of fun and enjoyment, and gambling problems over and above the variance accounted for by gender. Those with gambling problems were less likely to have the expectation that gambling would be fun than those without gambling problems. Despite NCAA efforts to curb gambling activity, the results suggest that college student-athletes are at risk for over-involvement in gambling. Therefore, it is important to explore gambling outcome expectancies within this group since the motivations and reasons for gambling might be able to inform treatment initiatives.     

Urge to Gamble in a Simulated Gambling Environment

Cue reactivity, while increasingly recognized as a central feature of drug and alcohol addiction, is not well studied in gambling. We evaluated the urge to gamble in a simulated casino environment among frequent gamblers who alternated between cycles in which they observed others playing ten hands of Blackjack (first, third and fifth cycle) and cycles in which they played ten hands of Blackjack themselves (second and fourth cycle). The played cycles served as a manipulation for the observed cycles in terms of “priming” (having previously gambled in the environment vs. not) and “anticipation” (expecting more opportunities to gamble in the environment vs. not) and, thus, allowed these conditions: observed cycle 1 = anticipation (+) and prime (−); observed cycle 2 = anticipation (+) and prime (+); and observed cycle 3 = anticipation (−) and prime (+). Subjects’ urge to gamble was greater in the gambling environment than in a neutral setting and both positive anticipation and positive priming increased cue reactivity within the gambling environment. The frequency of gambling outside of the study did not affect cue reactivity. However, a preference for Blackjack (vs. other types of gambling) and observing winning (vs. losing) hands were both associated with stronger cue reactivity in the study. These findings contribute to our understanding of pathological gambling.     

Reduced inhibitory control predicts persistence in laboratory slot machine gambling

Impairments in inhibitory control characterize a range of addictive behaviours including gambling disorder. This study investigated the relationship between a neuropsychological measure of inhibitory control and behaviour on a simulated slot machine that included a measure of gambling persistence, in a non-clinical sample of regular gamblers. Regular gamblers (n = 75) performed a laboratory slot machine task for 30 trials where they could win real money, followed by a persistence phase under extinction (i.e. without wins). Participants also completed a stop-signal task, along with measures of gambling-related cognitions, social desirability, and symptoms of disordered gambling. In hierarchical regression models, reduced inhibitory control was found to predict greater persistence and a higher subjective desire to play again after both wins and near-misses (i.e. unsuccessful outcomes close to the jackpot). These data illustrate the impact of low inhibitory control on relevant behavioural tendencies in a group of regular gamblers. Our results help elucidate a cognitive process that may contribute to problem gambling, with implications for screening and treatment.     

Gambling Participation,Expenditure and Risk of Harm in Australia, 1997–1998 and 2010–2011

Gambling-related harm results primarily from financial losses. Internationally Australia continues to rank as the largest spending nation per capita on gambling products. This would suggest that Australian gamblers are at disproportionately high risk of harm despite almost two decades of industry scrutiny and regulation, and investment in research, treatment and education programs. However, declines in participation rates, per capita expenditure, household expenditure, national disposable income spent on gambling and problem gambling rates have been cited as evidence that fewer people are gambling, that gamblers are spending less, and that gambling safety in Australia has improved. The current study investigated these propositions using national population and accounts data, and statistics from Australia’s two population-representative gambling surveys conducted in 1997–1998 and 2010–2011. Despite a falling participation rate the study found no real change in the number of people gambling overall, and increasing numbers consuming casino table games, race wagering and sports betting. Further found were increases rather than decreases in average gambler expenditure, overall, and across most products, particularly electronic gaming machines (EGMs). Potentially risky levels of average expenditure were observed in both periods, overall and for race wagering, casino table gaming, and EGMs. Changes in the proportion of income spent on gambling suggest risks declined overall and for race wagering and casino table gaming, but increased for EGMs. Finally, while problem gambling statistics were not comparable between periods, the study found double the number of moderate risk gamblers previously estimated for 2010–2011 amongst the 2 million Australians found to have experienced one or more gambling-related problems. The findings have implications for public health policy and resourcing, and the way in which prevalence and expenditure statistics have been interpreted by researchers, government and industry in Australia and elsewhere.     

Problem Gambling Family Impacts: Development of the Problem Gambling Family Impact Scale

Although family members of problem gamblers frequently present to treatment services, problem gambling family impacts are under-researched. The most commonly endorsed items on a new measure of gambling-related family impacts [Problem Gambling Family Impact Measure (PG-FIM: Problem Gambler version)] by 212 treatment-seeking problem gamblers included trust (62.5 %), anger (61.8 %), depression or sadness (58.7 %), anxiety (57.7 %), distress due to gambling-related absences (56.1 %), reduced quality time (52.4 %), and communication breakdowns (52.4 %). The PG-FIM (Problem Gambler version) was comprised of three factors: (1) financial impacts, (2) increased responsibility impacts, and (3) psychosocial impacts with good psychometric properties. Younger, more impulsive, non-electronic gaming machine (EGM) gamblers who had more severe gambling problems reported more financial impacts; non-EGM gamblers with poorer general health reported more increased responsibility impacts; and more impulsive non-EGM gamblers with more psychological distress and higher gambling severity reported more psychosocial impacts. The findings have implications for the development of interventions for the family members of problem gamblers.     

Limit your time,gamble responsibly: setting a time limit (via pop-up message) on an electronic gaming machine reduces time on device

In the current study, we assessed whether undergraduate electronic gaming machine (EGM) gamblers would be more apt to set a time limit and spend less time gambling when asked to consider setting an explicit time limit prior to their gambling session. To this end, participants (N = 43) were randomly assigned to a time limit pop-up condition or control condition, both of which involved gambling on an EGM in a virtual reality (VR) casino. In the time limit pop-up condition, participants were asked (via pop-up message) to consider setting a time limit on play and entering that limit in an available text box prior to commencing play. In the no time limit pop-up condition, participants engaged in play immediately upon accessing the EGM in the VR casino (i.e. they were not exposed to a time limit pop-up message). As predicted, participants who were explicitly asked to consider setting a time limit on their EGM play were significantly more likely to do so and spent less time gambling than those who were not given such instructions. The results provide preliminary support for the contention that setting a time limit on EGM play is an effective responsible gambling strategy.     

Social reward,conflict, and commitment: A theoretical model of gambling behavior

A theoretical model of gambling behavior is introduced which examines the linkage between regular gamblers, the gambling institution, and outside society. This model is based on participant observation in an urban casino and a review of the related literature. The intention is to explore the structural and cultural factors operating both in society at large and in a gambling institution and to connect them with the personal characteristics of avid regular gamblers to explain their gambling behavior and its consequences. The main conclusion is that the gambling institution with its social rewards and the perceived threatening nature of the wider social structure are the dominant forces in attracting gamblers and in shaping their subsequent gambling entanglement.     

Gambling Increases Self-Control Strength in Problem Gamblers

In two studies it is demonstrated that, in the short-term, slot machine gambling increases self-control strength in problem gamblers. In Study 1 (N = 180), participants were randomly assigned to either play slot machines or engage in a control task (word anagrams) for 15 min. Subsequent self-control strength was measured via persistence on an impossible tracing task. Replicating Bergen et al. (J Gambl Stud, doi:10.1007/s10899-011-9274-9, 2011), control condition participants categorized as problem gamblers persisted for less time than did lower gambling risk participants. However, in the slot machine condition, there were no significant differences in persistence amongst participants as a function of their gambling classification. Moreover, problem gambling participants in the slot machine condition persisted at the impossible tracing task longer than did problem gambling participants in the control condition. Study 2 (N = 209) systematically replicated Study 1. All participants initially completed two tasks known to deplete self-control strength and a different control condition (math problems) was used. Study 2 results were highly similar to those of Study 1. The results of the studies have implications for the helping professions. Specifically, helping professionals should be aware that problem gamblers might seek out gambling as a means of increasing self-control strength.     

Measuring Self-efficacy in Gambling: The Gambling Refusal Self-Efficacy Questionnaire

This paper reports on the development and psychometric properties of a Gambling Refusal Self-Efficacy Questionnaire (GRSEQ). Two hundred and ninety-seven gamblers from both normal and clinical populations completed an initial set of 31-items of which 26 were selected for inclusion in the final version of the GRSEQ. A series of factor analyses showed four clear factors accounting for 84% of the variance. These factors can be summarised as situations and thoughts associated with gambling, the influence of drugs on gambling, positive emotions associated with gambling and negative emotions associated with gambling. The GRSEQ total score and factors scores showed high internal consistency (Cronbach’s alpha ranging from 0.92 to 0.98). Participants experiencing problems with gambling scored significantly lower on the GRSEQ, and discriminant analyses showed that the scale is able to correctly classify the non-problem (i.e., community and student samples) and problem gamblers (i.e., clinical sample). Furthermore, the GRSEQ showed significant negative relationships with other gambling-related variables (gambling urge and gambling-related cognitions) and negative mood states (depression, anxiety and stress) and was shown to be sensitive to change in treatment of pathological gambling. The results suggest that the GRSEQ is a useful measure of gambling refusal self-efficacy that is suitable for assessment of gamblers from both normal and clinical populations.     

Gender differences in gambling preferences and problem gambling: a network-level analysis

Most gambling studies have a gender-blind research approach, although a large body of scientific evidence suggests that gambling in females is on the rise and that males and females have different gambling behaviours and experience specific gambling-related harm. This study addressed these gender differences using a network analysis, an innovative approach considering disorders/concepts as dynamic systems of interacting symptoms/items. Data on gambling activities, problem gambling, substance use and mental health were collected in a representative sample of French adult gamblers (n = 8805). The study capitalized on the network analysis directly to compare associations of specific gambling activities with gambling disorder symptoms separately for both genders. The network analysis revealed that problem gambling was strongly associated with gambling machines among females, whereas it was related to sports betting, poker and casino games among males. The networks that included substance use and mental health showed that substance use was related to specific gambling activities. These findings confirm the links between various gender-specific gambling patterns and problem gambling and suggest a need to consider these gender differences to improve prevention efforts. More broadly, the present study further supports the importance of gender differences for gambling research and policy.
