Behavioral characteristics of Internet gamblers who trigger corporate responsible gambling interventions

As the worldwide popularity of Internet gambling increases, concerns about the potential for gambling-related harm also increase. This paper reports the results of a study examining actual Internet gambling behavior during 10 years of play. We examined the electronic gambling records of subscribers (N = 2,066) who triggered a responsible gaming alert system at a large international online gaming company. We compared these cases with control subscribers (N = 2,066) who had the same amount of exposure to the Internet gambling service provider. We used discriminant function analysis to explore what aspects of gambling behavior distinguish cases from controls. Indices of the intensity of gambling activity (e.g., total number of bets made, number of bets per betting day) best distinguished cases from controls, particularly in the case of live-action sports betting. Control group players evidenced behavior similar to the population of players using this service. These results add to our understanding of behavioral markers for disordered Internet gambling and will aid in the development of behavior-based algorithms capable of predicting the presence and/or the onset of disordered Internet gambling.

FI SCHEDULES AND PERSISTENCE AT GAMBLING IN THE U.K. BETTING OFFICE

This study reports on the direct observations of customers in two U.K. betting offices gambling on horse and dog races. These observations revealed that bets were more frequently placed in the last minutes just prior to the start (the OFF), and that this was caused by high-frequency gamblers (customers who had eight or more bets in a session) consistently placing their bets in the last two minutes prior to the OFF. Low-frequency gamblers (three or fewer bets/session) avoided this time period placing their bets earlier, or after the OFF, i.e., on a later race. It was argued that the betting behavior of the “gamblers” could not be explained either in terms of “skillful betting” or solely in terms of variable ratio schedules but was more adequately accounted for in terms of an interval schedule. It was further suggested that time-based schedules might be of heuristic value in generally understanding persistence at gambling while losing.     

Episodic chasing in pathological gamblers using the Iowa gambling task

"Chasing ones losses" is a key symptom among pathological gamblers (PGs). This study focuses on quantitative differences in episodic chasing (i.e., sequences of disadvantageous decisions within a single gambling session) between PGs and non-pathological gamblers (NPGs). We compared 61 PGs and 39 NPGs on the Iowa Gambling Task (IGT) and the Zuckerman Sensation Seeking Scale (SSS). The PGs showed significantly more chasing and had significantly poorer decision-making strategies than NPGs, particularly among males (F = 4.52, p < 0.05). Random players were significantly less sensation seeking than advantageous and disadvantageous (i.e., chasing) players, but there was no interaction with group or gender. The results suggest that quantifiable within-session gambling behavior holds important implications for detecting underlying vulnerabilities to gambling pathology.     

Association of pathological gambling with depression in Scotland

Is most research concerning gambling and depression has been conducted on clinical populations, the present study examined the relationship between gambling and depression across a large sample in Scotland in higher education and the community. A questionnaire-based cluster design involved the distribution of the South Oaks Gambling Screen and the Centre for Epidemiologic Studies Depression Scale mainly to students and staff of higher educational establishments, with small community and gambling samples also included. Thirty-seven colleges and universities across Scotland participated in the research, with a sample of 2259 people aged sixteen years of age or over (M = 28.9 yr., SD = 13.4) being obtained. It was found that past-year probable pathological gamblers had significantly higher depression than problem gamblers, nonproblem gamblers, and nongamblers. However, when probable pathological gamblers who had sought treatment were omitted from the analysis, the nontreatment-seeking probable pathological gambling group no longer had significantly higher depression than the problem gambling group. Female problem and probable pathological gamblers had particularly high depressive symptomatology, suggesting co-morbid depression may be a prominent feature of problematic female gambling.     

Is perfectionism categorical or dimensional? A taxometric analysis

Considerable debate exists within the perfectionism literature regarding whether perfectionism is most accurately conceptualized as a dimensional or categorical construct. Specifically, some researchers have viewed perfectionism as a continuous construct, with extreme scores being associated with negative psychological outcomes (e.g., obsessive-compulsive disorder, eating disorders, etc.). In contrast, others have argued that two distinct forms of perfectionism exist (i.e., adaptive vs. maladaptive perfectionism) that are associated with both positive and negative outcomes. The purpose of this study was to examine the latent structure of perfectionism using taxometric procedures to determine whether perfectionism is most accurately conceptualized as taxonic (categorical) or dimensional (continuous). We applied four taxometric procedures (maximum eigenvalue [Waller & Meehl, 1998], maximum covariance [Meehl & Yonce, 1996], mean above minus below a cut [Meehl & Yonce, 1994], and latent-mode factor analysis [Waller & Meehl, 1998]) to perfectionism data collected from 2 large nonclinical samples. Results provided convergent evidence for a dimensional conceptualization of perfectionism across samples, perfectionism measures, and statistical procedures. We discuss the implications of these findings for the theory, assessment, and investigation of perfectionism are discussed.     

The role of money in the excitement of gambling

Many gamblers claim that gambling is intrinsically exciting, with money playing only a secondary role. To examine the effects of the expectancy of winning money, the authors randomly assigned 243 male college student gamblers to 1 of 6 experimental or 1 of 3 control conditions. Control participants either simply watched a videotaped horse race or they picked a horse, but without wagering; that horse later turned out to be either the winner of the race or the runner-up. Experimental participants wagered $1 on a horse for a chance of winning either USD 2, USD 7, or USD 15, with half winning and half losing their wagers. Wagering led to increased heart rates and subjective excitement as a function of the expected payoff and of winning as opposed to losing the wager. The study was replicated with 200 female college student gamblers with similar results. These findings support the notion that the excitement of gambling is tied to the expectancy of winning money.     

A violation of dominance and the consumption value of gambling

We document an apparently widespread violation of dominance in the horse‐racing betting market in the UK, and use the systematic variation in the incidence of this violation to estimate the consumption value of gambling. Betting‐shop gamblers in the UK face a tax on gambling of 10%, but have the choice of paying the tax either at the time of wager or on any return on a successful bet. It can be shown, however, that the latter act is strictly dominated by another action in which tax is paid on the wager. Despite this, more than 18% of bets appear to be placed by gamblers who choose to pay tax on the return. We explore the hypothesis that this apparent violation of rationality may be explained by a component of utility which represents the consumption value of gambling, which in turn varies with the amount wagered. We then estimate this component from a dataset consisting of a record of 25,000 individual bets using probit analysis of the tax decision. Copyright © 1999 John Wiley & Sons, Ltd.     

Predictors of irrational thinking in regular slot machine gamblers

Previous research has suggested that irrational thinking may play a central role in the maintenance of behavior in slot machine gambling (M. B. Walker, 1992b). The present study is an evaluation of the validity and predictors of irrational thinking in a sample of regular gamblers (N = 20) drawn from the general community. The results were generally consistent with earlier findings; 75% of gambling-related cognitions were found to be irrational. Irrationality was unrelated to the amount of money lost or won during sessions but was positively related to risk taking. The most common irrational cognitions included false beliefs concerning the extent to which outcomes could be controlled or predicted and the attribution of human qualities (personification) to gambling devices. Gender comparisons showed that women were more likely than men to personify the machines. The validity of the speaking-aloud approach and suggestions for future research are discussed.     

Special random numbers: Beyond the illusion of control

Previous research has shown that gamblers prefer numbers they choose themselves because this choice allows them to feel more in control of the (random) outcome. We identify other conditions under which people find numbers “special” (i.e., worthy of betting more on than other numbers). By manipulating gambling task type and assigning participants a number by an endogenous system outside their own control (as is done in numerology, astrology, and other paranormal systems), we find that indeed people prefer to bet on numbers derived from particular special systems. The mechanism underlying this preference is enjoyment with the task—not control. Further, the enjoyment associated with this “specialness” is related to the prevalence of certain types of numbers (i.e., numbers based on dates and names) in the fortune-telling world and not to other factors such as individuality or even belief in the associated system. We replicate these findings using actual money and show that this prevalence-to-enjoyment link already exists in memory for dates and names and is activated and strengthened by priming the fortune-telling systems relevant to those special random numbers. Finally, we present a model of special random numbers that integrates our findings with other determinants of valuation such as regret and subjective probability. Our results expand the realm of special random numbers beyond control. Our enjoyment model has implications not only for understanding gambling, but also for understanding how reasoning under uncertainty is influenced by little-understood phenomena (such as fortune-telling systems) without affecting subjective probability or actual beliefs.     

Subtyping pathological gamblers on the basis of affective motivations for gambling: relations to gambling problems, drinking problems, and affective motivations for drinking

Pathological gamblers who drink when gambling (n=158; 77% men; mean age=36.0 years) completed the Inventory of Gambling Situations (IGS) and gambling and drinking criterion measures. Principal components analysis on the IGS subscales revealed negative (e.g., Unpleasant Emotions) and positive (e.g., Pleasant Emotions) gambling situation factors. Subjecting IGS factor scores to cluster analysis revealed three clusters: (a) enhancement gamblers, with low negative and high positive factor scores; (b) coping gamblers, with very high negative and high positive factor scores; and (c) low emotion regulation gamblers, with low negative and positive factor scores (59%, 23%, and 18% of the sample, respectively). Clusters were validated with a direct measure of gambling motives. Additional validity analyses showed that coping gamblers scored higher than the other groups on a variety of different gambling activities, gambling problems, drinking frequency, drinking problems, and coping drinking motives, whereas low emotion regulation gamblers scored lower than the other groups on gambling frequency, gambling problems, drinking quantity, and enhancement drinking motives. The findings validate this empirical approach to subtyping gamblers and suggest consistency of motives across addictive behaviors.

Pilot Study of a Personalized Feedback Intervention for Problem Gamblers

A pilot study was conducted of a personalized feedback intervention for problem gamblers. Respondents (N = 61) were recruited from an ongoing gambling research study to take part in another study to help us “develop and evaluate self-help materials for gamblers.” Respondents were randomly assigned to receive a personalized feedback summary or to a waiting list control. At 3-month follow-up (80.3% follow-up rate, N = 49), after controlling for baseline demographic characteristics and gambling severity, respondents in the feedback condition displayed some evidence that they were spending less money on gambling than those in the control condition. Further, ratings of the usefulness of the feedback summary were positive and most recipients (96%) recommended that they be made available to other gamblers interested in evaluating or modifying their gambling. Given these promising pilot results, a full-scale evaluation of these personalized feedback materials would appear justified. An online version of the intervention is now also available at www.CheckYourGambling.net.     

Psychobiology of the near-miss in fruit machine gambling

Explanations involving the etiology of pathological gambling have tended to emphasize psychosocial factors. However, the possibility that psychobiological factors may be important in the development of pathological gambling behavior should not be ruled out. Psychobiological approaches are becoming ever more prominent with the three main lines of research being (a) a search for a physiological disposition and/or underlying biological substrate in pathological gamblers, (b) an examination of the role of arousal in gambling, and (c) speculation about endorphin-related explanations. The data from questionnaires and interviews with fruit machine gamblers suggest that both physiological and cognitive factors (e.g., the psychology of the near-miss) may be important in the explanation of excessive fruit machine gambling. Thus, if a gambler becomes physiologically aroused when he or she wins or nearly wins, it will stimulate further play, here termed the psychobiology of the near-miss.     

Online guidance, advice, and support for problem gamblers and concerned relatives and friends: an evaluation of the GamAid pilot service

The paper reports one of the first ever studies to evaluate the effectiveness of an online help and guidance service for problem gamblers. The evaluation utilised a mixed methods design in order to examine both primary and secondary data relating to the client experience. In addition, the researchers posed as problem gamblers in order to obtain first-hand experience of how the service works in practice. A total of 80 participants completed an online evaluation questionnaire, and secondary data were gathered from 413 distinct clients who contacted an advisor. It was concluded that the service appears to be one of the few genuinely international guidance and 'counselling' services available to problem gamblers. Gambling online was the most preferred form of gambling and gambling location of GamAid clients. The service also appears to be favoured by females more than any other comparable service. Overall, the vast majority of clients were very positive about their experience of using GamAid, although there were some minor technical difficulties. In light of the findings, the utility of using online guidance and therapeutic services is discussed.

Measurement and structure of pathological gambling behavior

The serious effects of pathological gambling on both gamblers and their families warrants research on the disorder. This study aimed at identifying components of pathological gambling with the goal of developing methods for early detection and preventive strategies. A factor analysis of behaviors hypothesized to relate to pathological gambling resulted in a multidimensional model of the disorder. Eight factors were identified, including distinct neurotic, psychopathic, and impulsive components, and used in a comparative analysis of 83 admitted compulsive gamblers and 61 nongamblers. Five of the factors differentiated the two groups even when sex, age, and education were controlled. Implications of these findings are discussed.     

CARACTÉRISTIQUES PSYCHOLOGIQUES DE LA PRISE DE RISQUE MONÉTAIRE DES JOUEURS ET DES NON-JOUEURS À LA ROULETTE*

This study compares different dimensions of the personality, the perception of control and risk-taking behavior of gamblers and non-gamblers exposed to American roulette. The analyses of the data revealed that no significant differences emerged among the two groups on personality or perception of control. Although gamblers started the game by stacking more money than non-gamblers, the latter rapidly bet as much as the regular gamblers. Furthermore, risk-taking behavior increased as the game progressed. The practical implications of the data are discussed in relation to the psychology of gambling.     

Gambling behavior and gambling problems in Norway 2007

In Norway, legalized gambling is pervasive, easily accessible and socially accepted, particularly the participation in national lotteries. We conducted a stratified probability sample study during January–March 2007 (age group 16–74 years, N  = 3,482, response rate 36.1%) to assess gambling behavior and prevalence of problematic gambling by the NORC Diagnostic Screen (NODS). Overall, 67.9% of the study population had been engaged in past-year gambling and 0.7% were past-year problematic gamblers (NODS score 3+). Male gender, low educational level, single marital status, and being born in a non-Western country were variables positively associated with problematic gambling. Past-year problematic gamblers indicated the slot machine (34.6%) and Internet gambling (26.9%) as the most important games, while most non-problematic gamblers pointed out the lotteries (62.3%) as the most important game. The prevalence of self-reported sleeping disorders, depression and other psychological impairments was significantly higher among problematic gamblers. Gambling problems affect people's lives in multiple ways.     

Social Deviancy and Suicidal Behavior

Abstract

In this study lottery gambling behavior of 288 American college students was examined. Although most students were infrequent gamblers, we found that student lottery gambling was related to having parents and friends who were lottery gamblers. Students who were frequent lottery gamblers were more likely to participate in other forms of gambling and to have begun gambling at younger ages than less frequent gamblers. Locus of control was related to more frequent gambling among parents and only marginally related to more frequent lottery play among students. Discriminant analysis using parental gambling, peer gambling, games played, sex, and locus of control could predict frequency of lottery playing for 72% of gamblers and nongamblers.
