Development of the Drake Beliefs about Chance Inventory

The present research describes the development and validation of a cognitive assessment instrument, the Drake Beliefs about Chance (DBC) inventory, designed to determine and quantify erroneous beliefs about games of chance. Principal components analyses showed that the DBC assesses two primary dimensions, Illusion of Control and Superstition. Correlation analyses showed that scores on these two dimensions are related to higher frequency of gambling behaviors in both adults from the general population and clients from gambling treatment centers. Of the two sets of erroneous beliefs, Illusion of Control was a better predictor of gambling than Superstition. This investigation provides additional evidence that participants in games of chance such as casino gamblers possess certain classes of erroneous beliefs regarding the games they play.     

Examining DSM-IV Criteria for Pathological Gambling: Psychometric Properties and Evidence from Cognitive Biases

We examined the DSM-IV criteria for pathological gambling as assessed with the DSM-IV-based Diagnostic Interview for Gambling Severity (DIGS; Winters, Specker, & Stinchfield, 2002). We first analyzed the psychometric properties of the DIGS, and then assessed the extent to which performance on two judgment and decision-making tasks, the Georgia Gambling Task (Goodie, 2003) and the Iowa Gambling Task (Bechara, Damasio, Damasio, & Anderson, 1994), related to higher reports of gambling pathology. In a sample of frequent gamblers, we found strong psychometric support for the DSM-IV conception of pathological gambling as measured by the DIGS, predictive relationships between DIGS scores and all cognitive performance measures, and significant differences in performance measures between individuals with and without pathological gambling. Analyses using suggested revisions to the pathological gambling threshold (Stinchfield, 2003) revealed that individuals meeting four of the DSM-IV criteria aligned significantly more with pathological gamblers than with non-pathological gamblers, supporting the suggested change in the cutoff score from five to four symptoms. Discussion focuses on the validity of the DSM-IV criteria as assessed by the DIGS and the role of cognitive biases in pathological gambling.     

The Gambling Cognitions Inventory: scale development and psychometric validation with problem and pathological gamblers

Cognitive distortions are typically identified as an important etiological factor in pathological gambling. The Gambling Cognitions Inventory (GCI) developed by Holub (2003) is examined in this study using a sample of 710 pathological gamblers collected in four Canadian studies. Confirmatory factor analysis did not support the initial 40-item scale and suggested a 33-item scale. The sample was split into two groups to conduct exploratory and confirmatory factor analyses. Scree plots and parallel analysis suggested a two-factor scale. The scale developed by exploratory factor analysis on the first sample was supported by confirmatory factor analysis on the second sample (CFI>0.95; RMSEA < 0.05). The two factors indicated a Skill and Attitude subscale and a Luck and Chance subscale. Analysis conducted within each of the four studies showed good internal reliability for the scale (range of α = 0.91–0.95) and subscales (α = 0.77–0.92). The scale and subscales correlated with gambling severity measures as well as other measures of gambling cognitions including the Gambling Attitudes and Beliefs Scale and the Gambling Beliefs Questionnaire. The results of the study indicate that the GCI is a psychometrically strong scale and may be beneficial in directing cognitive therapy to the most problematic cognitions.     

Psychometric Evaluation of the Problem Gambling Severity Index-Chinese Version (PGSI-C)

The purpose of this study was to examine the psychometric properties of the Chinese 9-item Problem Gambling Severity Index (PGSI) derived from the 31-item Canadian Problem Gambling Index (CPGI) originally developed by Ferris and Wynne (2001). Exploratory factor analysis (EFA; n = 386; Group A data) and confirmatory factor analysis (CFA; n = 387; Group B data) on the Chinese student and community data (Mean age = 25.36 years) showed that a unifactorial model fitted the data with good reliability score (Cronbach’s alpha = 0.77). The concurrent validity of the PGSI-C was good in terms of the Chinese data matching the expected correlation between PGSI-C and other variables or scales such as SOGS, gambling frequency, gambling urge, gambling cognitions, depression, anxiety, and stress. The scale also reported good discriminant and predictive validity. In sum, the PGSI-C has good psychometric properties and can be used among Chinese communities to identify at-risk problem gamblers. Implications and suggestions for future research are discussed.     

Gambling Motives: Do They Explain Cognitive Distortions in Male Poker Gamblers?

Gambling behavior is partly the result of varied motivations leading individuals to participate in gambling activities. Specific motivational profiles are found in gamblers, and gambling motives are closely linked to the development of cognitive distortions. This cross-sectional study aimed to predict cognitive distortions from gambling motives in poker players. The population was recruited in online gambling forums. Participants reported gambling at least once a week. Data included sociodemographic characteristics, the South Oaks Gambling Screen, the Gambling Motives Questionnaire-Financial and the Gambling-Related Cognition Scale. This study was conducted on 259 male poker gamblers (aged 18–69 years, 14.3% probable pathological gamblers). Univariate analyses showed that cognitive distortions were independently predicted by overall gambling motives (34.8%) and problem gambling (22.4%) (p < .05). The multivariate model, including these two variables, explained 39.7% of cognitive distortions (p < .05). The results associated with the literature data highlight that cognitive distortions are a good discriminating factor of gambling problems, showing a close inter-relationship between gambling motives, cognitive distortions and the severity of gambling. These data are consistent with the following theoretical process model: gambling motives lead individuals to practice and repeat the gambling experience, which may lead them to develop cognitive distortions, which in turn favor problem gambling. This study opens up new research perspectives to understand better the mechanisms underlying gambling practice and has clinical implications in terms of prevention and treatment. For example, a coupled motivational and cognitive intervention focused on gambling motives/cognitive distortions could be beneficial for individuals with gambling problems.     

Instant Ticket Purchasing by Ontario Baby Boomers: Increasing Risk for Problem Gamblers

Instant ticket purchase gambling (ITPG) is pervasive in Ontario and has features that mimic slot machine play. Previous researchers have reported that ITPG is one preferred activity for at-risk/problem gamblers. In the general Canadian population, rate of participation in ITPG is second only to lottery ticket gambling. Both are particularly favored by youth and seniors. The next cohort of seniors will be Canada’s baby boomers, one-third of whom live in Ontario. Secondary analysis of Statistics Canada data revealed that adults in this cohort who buy instant gambling tickets (N = 1781) are significantly different from the complete group of their age peers (N = 4266) in number of activities pursued and frequency of involvement. At-risk/problem gambling prevalence was 10.2% amongst Ontario baby boomers who participate in instant ticket gambling, significantly higher than the 6.7% found amongst the total group of baby boom gamblers. For those who reported experiencing one or more of the Canadian Problem Gambling Index indicators for problem gambling (N = 237), 73% were buying instant tickets. Future research should consider cohort effects and explore combinations of preferred gambling activities that may increase risk for problem gambling. Social policy recommendations include the use of all ITPG venues as key locations for promoting awareness of problem gambling treatment services. This work was funded by Ontario Problem Gambling Research Centre.     

Alexithymia and Gambling: A Risk Factor for All Gamblers?

The purpose of this study was to investigate alexithymia (in relation with depression) in three groups of French gamblers (n = 186) recruited in their gambling location: at the racetracks (n = 80 males; mean age 28.1 years), in the slot machine rooms (n = 65; 29 males, 36 females; mean age 34.6 years), and in the traditional gaming rooms (n = 41 males; mean age 36 years). Gambling behavior was measured by the South Oaks Gambling Screen and DSM-IV criteria for pathological gambling, Alexithymia by the Toronto Alexithymia Scale (TAS-20) and depression with the Beck Depression Inventory (BDI-13). For racetracks and slot machine gambling, pathological gamblers differed from non-pathological gamblers, regarding their alexithymia scores. These results remained stable after controlling for depression scores among the racetracks gamblers only. The relationship between alexithymia and depression depends on the type of pathological gambler. These findings are consistent with the idea of identifying clinically distinct subgroups of gamblers.     

Divergent Validity of Measures of Cognitive Distortions, Impulsivity, and Time Perspective in Pathological Gambling

The present study assessed the divergent validity of several self-report and objective behavioral measures for assessing pathological gambling using three samples divided by South Oaks Gambling Scale score [Lesieur, & Blume (1987). American Journal of Psychiatry, 144, 1184–1188]: pathological gamblers, potential pathological gamblers, and non-pathological gamblers. Self-report measures included the Gamblers’ Beliefs Questionnaire [GBQ; Steenbergh, Meyers, May, & Whelan (2002). Psychology of Addictive Behaviors, 16, 143–149], the Gambling Passion Scale [GPS; Rousseau, Vallerand, Ratelle, Mageau, & Provencher, (2002). Journal of Gambling Studies, 18, 45–66], the Eysenck Impulsivity Questionnaire [EIQ; Eysenck, & Eysenck (1978). Psychological Reports, 43, 1247–1255], and the Stanford Time Perspective Inventory [STPI; Zimbardo, & Boyd (1999). Journal of Personality and Social Psychology, 77, 1271–1288]. Behavioral tasks included the delay discounting task [Madden, Petry, Badger, & Bickel (1997). Experimental & Clinical Psychopharmacology, 5, 256–263] and the Future Time Perspectives [FTP; Wallace (1956). Journal of Abnormal Psychology, 52, 240–245]. The GBQ, GPS, Impulsivity subscale of the EIQ, and DDT all exhibited robust divergent validity, however, neither measure of time perspective discriminated between groups. Applications of these findings to etiological research and clinical contexts are discussed.This work was originally presented in November, 2003 at the 37th annual convention of the Association for the Advancement of Behavior Therapy in Boston, MA.     

Development and Psychometric Evaluation of a 10-Item Short Form Inventory of Gambling Situations

The Inventory of Gambling Situations (IGS-63; Turner and Littman-Sharp, Inventory of gambling situations users guide, 2006) is a 63-item measure of high-risk gambling situations. It assesses gambling across 10 situational subscales that load onto two higher-order factors: negative and positive situations (Stewart et al. Psychology of Addictive Behaviors, 22:257–268, 2008). While the IGS-63 has excellent psychometric properties (Littman-Sharp et al., The Inventory of Gambling Situations: Reliability, factor structure, and validity (IGS Technical Manual), in press) its length may preclude its use in time-limited contexts. The purpose of this study was to develop and validate a 10-item short-form of the IGS (IGS-10). Each IGS-10 item reflects one of the ten subscale categories from the IGS-63, with two items from the original subscales included as examples for each IGS-10 item. The IGS-10 was administered to 180 undergraduate gamblers along with the IGS-63 and the Problem Gambling Severity Index (PGSI; Ferris and Wynne, Canadian Problem Gambling Index: Final report, 2001). IGS-10 items showed convergent validity with the corresponding IGS-63 subscales (r’s = .60–.73). Principal components analysis of the IGS-10 revealed two factors: negative (α = .84) and positive (α = .85). PGSI scores correlated significantly with all IGS-10 items (r’s = .33–.58) and with both IGS-10 higher-order subscales (r’s = .66 [negative] and .49 [positive]), supporting the criterion validity of the IGS-10. Since minimal information is lost when using the IGS-10, the short form may prove particularly useful when respondent burden prevents using the full IGS-63.     

Validation of the Consumption Screen for Problem Gambling (CSPG)

A 3 item screen for problem gambling was developed based on a conceptual analogue of the Alcohol Use Disorders Identification Test—Consumption (Bush et al. in Arch Intern Med 158:1789–1795, 1998); a brief screen that measures consumption rather than harm. Data were collected from an email panel survey of 588 men and 810 women (n = 1,398) across all states in Australia. Respondents indicated their consumption of gambling products using the 3 items of the new Consumption Screen for Problem Gambling (CSPG). Receiver Operating Characteristics curve analysis was used to analyze the performance of the new items relative to the Problem Gambling Severity Index (Ferris and Wynne in The Canadian problem gambling index: Final report, 2001). Results show a 98% probability that the CSPG score for a randomly chosen positive case of problem gambling will exceed the score for a randomly chosen negative case. In addition, a score of 4+ on the CSPG identified all 14 cases of Problem Gambling correctly, while only 7.3% of non-problem gamblers had scores of 4+ (sensitivity = 100%; specificity = 92.7%). Lastly, only 3.0% of respondents without any gambling problems had CSPG scores of 4+. The current study suggests that the CSPG, a brief consumption-based measure for gambling products, can quickly and accurately identify people who are likely to be experiencing gambling problems.     

Offspring of Parents with Gambling Problems: Adjustment Problems and Explanatory Mechanisms

We compared offspring of problem gamblers (n = 42) to offspring of parents without gambling problems (n = 100) to see (1) whether the two groups differed with respect to depressive feelings and conduct/antisociality problems and (2) whether ineffective parenting or the offspring’s own gambling problems played a mediating role in this context. Participants were drawn from a relatively large community-based study (N = 1,872). Parents rated their own gambling and other mental health problems when their children were in mid-adolescence. The children’s self-reports on depressive feelings and conduct/antisociality problems were assessed at two points in time: by mid-adolescence and again by early adulthood. Results showed that children of parents with gambling problems reported more depressive feelings and more conduct problems by mid-adolescence than children of parents without gambling problems. Children of problem gamblers also experienced an increase in their depressive symptoms from mid-adolescence to early adulthood. Importantly, ineffective parenting, but not children’s gambling problems, mediated almost all the links between parental problem gambling and children’s adjustment problems. These results add to a very small data base showing that children of problem gamblers are at risk for a variety of adjustment problems.

Experimental Analysis of the Game in Pathological Gamblers: Effect of the Immediacy of the Reward in Slot Machines

Slot machines are the most “addictive” games because (a) the disorder (pathological gambling) appears more rapidly in these games than with any other; (b) most patients who seek professional help are mainly addicted to electronic gambling, and (c) even though it is not the more frequent game, most of all the money spent on legal games of chance (at least in Spain) goes to slot machines. Structural characteristics of slot machines induce to gamble because electronic games show the main parameters of operant conditioning, mainly the immediacy of the reinforcement. Ten pathological gamblers played slot machine in two conditions: immediate and delayed reinforcement. The results corroborate the importance of the immediacy of the reinforcement in gambling, because when the result appears immediately (after 2 s), more games are played than when the result is delayed only 10 s. Critical issues in problem gambling prevention and public health are discussed.     

Pathological Gambling in Estonia: Relationships with Personality,Self-Esteem,Emotional States and Cognitive Ability

Due to changes in gambling accessibility during the last decade gambling has become more widespread in Estonia and the prevalence of pathological gambling has sharply increased. The present study attempts to identify psychological characteristics of Estonian pathological gamblers. It has been shown that a wide range of social, economic, and individual factors (e.g. personality traits and emotional states) predict the likelihood of becoming a pathological gambler. In the present study, pathological gamblers’ (N = 33) personality traits, self-esteem, self-reported emotional states and cognitive ability were compared to the respective characteristics in a non-gambling control group (N = 42) matched for age, gender and educational level. It was found that compared to controls, pathological gamblers had higher scores on Neuroticism (especially on its immoderation facet) and lower scores on Conscientiousness (especially on its dutifulness and cautiousness facets) and on self-esteem scale. They reported more negative emotional states during the previous month (especially depression and anxiety). Finally, pathological gamblers had lower general cognitive ability. In a logistic regression model, the likelihood of being a pathological gambler was best predicted by high immoderation score and low cognitive ability.

Poker Mania and Problem Gambling: A Study of Distorted Cognitions,Motivation and Alexithymia

This study examines the relationships between distorted cognitions, motivation, and alexithymia on problem gambling in poker players (n = 96). Respondents completed questionnaires containing the Canadian Problem Gambling Index, Gambling Motivation Scale, Gambler’s Beliefs Questionnaire, and Toronto Alexithymia Scale-20. The results suggest that problem gambling is significantly related to distorted cognitions, non-self-determined motivation, and difficulty identifying feelings. Implications are drawn for the development of more relevant intervention, prevention, and treatment strategies.     

Cognitive distortions in heavy gambling

A sample of 38 regular and heavy gamblers, recruited through advertisements and not seeking treatment, were asked to describe special strategies, techniques or rituals that they used to increase their chances of winning at gambling in an open-ended interview. The mean South Oaks Gambling Screen Score for the sample was 7.7 with 64% of the sample scoring higher than 4. Their responses reflected multiple means by which the individual believed they were able to control (i.e., active illusory control, passive illusory control), reframe (i.e., interpretive control), or predict (i.e., probability control, predictive control) gambling outcomes. A larger number of cognitive distortions was associated with playing games in which skill was potentially a component (e.g., cards, sports) than in non-skill games (e.g., lotteries) as well as a positive family history of gambling. There were no sex differences. Implications of these findings for the cognitive psychopathology of gambling are discussed.     

Defining a threshold of harm from gambling for population health surveillance research

The measurement of harm in the context of non-problem gambling has received little attention from researchers in the field. Using the combined data from six provincial gambling surveys conducted in Canada between 2001 and 2005 (N = 12,285), we compared how different thresholds of defining gambling-related harm impacts prevalence, the relationship with indicators of gambling intensity and the characteristics of non-pathological gamblers who report experiencing below threshold symptoms of problem gambling. Survey items defining harm were drawn from the Problem Gambling Severity Index (PGSI) of the Canadian Problem Gambling Index. Three definitions of harm – reporting one or more problem gambling symptoms, reporting two or more problem gambling symptoms and having a PGSI score ≥ 3 – demonstrated a strong relationship with indicators of gambling intensity, and reliably differentiated low-threshold and zero symptom problem gamblers in terms of gambling characteristics and other risk factors.     

Assessing the Reliability of the Gambling Functional Assessment: Revised

Dixon and Johnson (Anal Gambl Behav 1: 44–49, 2007) proposed the Gambling Functional Assessment as a tool to identify the consequences maintaining the respondent’s gambling behavior, but subsequent studies on its psychometric properties suggested that it could use improvement. The present study investigated the internal consistency of the Gambling Functional Assessment—Revised using the responses of 1,060 undergraduate students. Temporal reliability was assessed by a second administration of the measure four (n = 87) or twelve (n = 98) weeks after the first administration. Temporal reliability was also compared to the South Oaks Gambling Screen (Lesieur and Blume in Am J Psychiatry 144: 1184–1188, 1987), which was also administered at both time points. Internal consistency measures were good to excellent, even when potential non-gamblers were excluded from the analyses. Temporal stability was also very good, with the possible exception of the consequence of “escape” at 12 weeks. The Gambling Functional Assessment—Revised represents a potentially useful tool for researchers and therapists interested in why respondents are gambling.     

Predictors of adverse gambling related consequences among adolescent boys

Although gambling is illegal for minors, adolescents do gamble and even higher proportions of adolescents than adults are at risk to become problem gamblers. Moreover, many adolescents suffer from a wide range of gambling related harms, and this study sought to examine what predicts different adverse consequences of adolescent gambling. Our aim was to test whether various cognitive, motivational and behavioural factors were associated with psychosocial consequences and loss of control, and with interpersonal and financial consequences of gambling, as measured by the Canadian Adolescent Gambling Inventory, the only instrument developed specifically for use on adolescents. The data was collected on a convenience sample of 1330 male Croatian students (Mage = 16.58, SDage = 1.16) from all three types of secondary education in Croatia. Results show that a high proportion of adolescents gamble, and that almost half of them are either at risk or can already be considered problem gamblers. Sport betting, VLT machines and betting on virtual horse races were the most frequent gambling activities for Croatian high-school boys. Hierarchical regression models showed that psychosocial consequences and loss of control can be predicted by higher frequency of gambling, previous experience with winning money and a specific motivation to earn money gambling, to become a better gambler and with having a drive to continue gambling after winning. On the other hand, interpersonal and financial consequences were predicted again by a higher frequency of gambling, the motive to be a better gambler and the drive to continue gambling after winning, but also by specific motivation to relax and feel better. Having more cognitive distortions, specifically having poorer understanding of chance and probabilities and more superstitious beliefs, as well as engagement in general risky and antisocial behaviour also predicted more interpersonal and financial consequences. Findings are discussed in the context of practical implications for prevention programs of adolescent gambling.     

An Assessment of the Psychometric Properties of Lithuanian Versions of DSM-IV-MR-J and SOGS-RA

Objective: Since no Lithuanian instrument focuses specifically on the measurement of pathological gambling in adolescence, we aimed to adapt commonly used international instruments (SOGS-RA, DSM-IV-MR-J) and assess their psychometric properties. Methods: Cross-cultural adaptation of DSM-IV-MR-J and SOGS-RA was performed in several steps including translations, synthesis of translations, back-translations, expert committee review, and pre-testing. Adapted instruments were administered to randomly selected adolescents in grades V through XII from all schools in the second largest Lithuanian city (Kaunas). Results: The DSM-IV-MR-J identified 4.2% of the representative sample as pathological gamblers, whereas the SOGS-RA generated prevalence of 5.2%. Cronbach’s alpha for DSM-IV-MR-J in this sample was 0.80 and 0.75 for the SOGS-RA. The correlation coefficient between the SOGS-RA and the DSM-IV-MR-J was statistically significant (Pearson correlation = 0.892, P < 0.001). Using the DSM-IV-MR-J as the baseline for pathological gambling in adolescence, the overall classification accuracy of the SOGS-RA was judged to be adequate, correctly identifying 34 out of 35 pathological gamblers (Kappa = 0.833, P < 0.001). Conclusions: The Lithuanian versions of DSM-IV-MR-J and SOGS-RA exhibited acceptable validity and reliability. The DSM-IV-MR-J was found to be a more conservative measure of pathological gambling.     

Numerical Reasoning Ability and Irrational Beliefs in Problem Gambling

Numerous studies have shown that pathological gamblers are particularly prone to various cognitive biases that may explain why they continue to gamble despite having occurred substantial losses. A common explanation advanced to account for this finding is that pathological gamblers may have poorer numerical or statistical knowledge than other people. Addressing these deficits is therefore seen as one possible way in which to assist pathological gamblers or prevent the development of problematic behaviour within the broader community. The aim of this study was test this assumption by assessing the numerical reasoning skills, objective gambling knowledge and tendency towards biased reasoning in a sample of 90 regular poker-machine gamblers (pathological and non-pathological) and a non-gambling comparison group (n = 45). Analyses based on both group comparisons and regression analyses controlling for differences in educational attainment showed that pathological gamblers scored significantly higher on the cognitive biases measure than other gamblers. However, this difference could not be attributed to poorer knowledge of gambling odds or limited numerical ability among pathological gamblers. The findings suggest that educating pathological gamblers with greater knowledge about the odds of gambling is unlikely to be an effective harm minimisation strategy.
