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.     

Adaptation and validation of the Japanese version of the Gambling Urge Scale

In Japan, accurately assessing and targeting gambling urges is important for the treatment of gambling disorder because people are constantly exposed to external triggers that elicit gambling urges. However, a valid measure that assesses gambling urges has not been adequately established. Therefore, the purpose of this study was to examine the psychometric properties of the Japanese version of the Gambling Urge Scale (GUS-J), which is a well-known valid 6-item instrument in English-speaking countries. Two hundred and thirty-nine participants completed questionnaires, 86 of which met the criteria for a probable gambling disorder. As with the original GUS, the GUS-J was demonstrated to be a one-factor model that accounted for 63.82% of the total item variance, with all items demonstrating loadings of .40 or higher. With regard to reliability, the GUS-J showed good internal consistency (α = .88). Furthermore, validity based on evidence of relationships with other variables, especially convergent and concurrent validity of the GUS-J, were supported by several analyses that examined hypotheses based on previous findings. In conclusion, this study showed that the GUS-J has good psychometric properties as an assessment tool for gambling urges in Japanese people and it will be useful for future clinical practice and research.     

A Canadian Population Level Analysis of the Roles of Irrational Gambling Cognitions and Risky Gambling Practices as Correlates of Gambling Intensity and Pathological Gambling

Using population data (N = 11,562) drawn from five Canadian gambling prevalence surveys conducted between 2000 and 2005, the current study investigated the relationship between irrational gambling cognitions and risky gambling practices upon (a) gambling intensity, as measured by percent of income spent on gambling and (b) tolerance, a diagnostic indicator of pathological gambling. First, we found irrational gambling cognitions and risky gambling practices to be positively related. Second, irrational gambling cognitions moderated the relationship between risky gambling practices and gambling intensity. Specifically, people engaging in risky practices, spent less of their income on gambling when they had fewer irrational gambling cognitions compared to those with more irrational cognitions. Third, irrational gambling cognitions moderated the relationship between risky gambling practices and tolerance. Of the people engaging in risky practices, those with no irrational cognitions reported lower levels of tolerance than those with at least one irrational cognition. Interactions with gender are reported and discussed. These findings demonstrate the importance of both gambling cognitions and gambling practices upon the intensity of gambling and pathological gambling.

Assessing the Playing Field: A Prospective Longitudinal Study of Internet Sports Gambling Behavior

Internet gambling is growing rapidly, as is concern about its possible effect on the public’s health. This paper reports the results of the first prospective longitudinal study of actual Internet sports gambling behavior during eight study months. Data include recorded fixed-odds bets on the outcome of sporting contests and live-action bets on the outcome of events within contests for 40,499 Internet sports gambling service subscribers who enrolled during February 2005. We tracked the following primary gambling behaviors: daily totals of the number of bets made, money bet, and money won. We transformed these variables into measures of gambling involvement. We analyzed behavior for both fixed-odds and live-action bets. The median betting behavior of the 39,719 fixed-odds bettors was to place 2.5 bets of €4 (approximately $5.3 US) every fourth day during the median 4 months from first to last bet. This typical pattern incurred a loss of 29% of the amount wagered. The median betting behavior of the 24,794 live-action bettors was to place 2.8 wagers of €4 every fourth day during the median duration of 6 weeks at a loss of 18% of the amount wagered. We also examined the behavior of empirically determined groups of heavily involved bettors whose activity exceeded that of 99% of the sample.     

Frequent Card Playing and Pathological Gambling: The Utility of the Georgia Gambling Task and Iowa Gambling Task for Predicting Pathology

The current investigation examined performance on two laboratory-based gambling tasks, the Georgia Gambling Task (GGT; Goodie, 2003. The effects of control on betting: Paradoxical betting on items of high confidence with low value. Journal of Experimental Psychology: Learning, Memory, and Cognition, 29, 598–610) and the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994. Insensitivity to future consequences following damage to human prefrontal cortex. Cognition, 50, 7–15), as well as self-reported markers of gambling pathology using the Diagnostic Interview for Gambling Severity (DIGS; Winters, Specker, & Stinchfield, 2002. The downside: Problem and pathological gambling (pp. 143–148). Reno, NV: University of Nevada, Reno) among a sample of undergraduate students who are frequent card players. Two hundred twenty-one participants (55 female and 166 male; mean age 19.21 years) who self-classified as playing cards at least once per month completed these measures. Performance on GGT and IGT systematically related to gambling-related pathology in several ways. Overconfidence and bet acceptance on the GGT, and myopic focus on reward on the IGT, predicted gambling related pathology. GGT and IGT performance correlated with each other, but both contributed independently to predicting gambling pathology. Card playing frequency predicted gambling pathology but not GGT or IGT performance. Discussion focuses on the role of biases of judgment and risky decision making in pathological gambling.     

Gambling Control Self-efficacy as a Mediator of the Effects of Low Emotional Intelligence on Problem Gambling

This study investigated whether lower emotional intelligence would be related to less self-efficacy to control gambling and more problem gambling and whether gambling self-efficacy would mediate the relationship between emotional intelligence and problem gambling. A total of 117 participants, including 49 women and 68 men, with an average age of 39.93 (SD = 13.87), completed an emotional intelligence inventory, a gambling control self-efficacy scale, and a measure of problem gambling. Lower emotional intelligence was related to lower gambling self-efficacy and more problem gambling. Gambling control self-efficacy partially mediated the relationship between emotional intelligence and problem gambling.     

Adolescent Gambling: Understanding the Role of Stress and Coping

The central variables of stress, coping, and gambling severity were examined along three lines of inquiry. The first addressed whether adolescents with gambling problems reported a greater number of minor or major stressful (i.e., negative) life events relative to others. The second examined whether more with gambling problems employed less-effective coping styles, such as those characterized as less task- or solution-focused, and more emotion- or avoidance-focused coping. Finally, the third question explored whether adolescents’ coping styles mediated the association between stress and gambling severity. Ranging from 11 to 20 years of age, 2,156 high-school students completed instruments assessing gambling involvement, gambling severity, stressful life events, and coping styles. Results indicated that, overall, adolescents with gambling-related problems reported more negative life events relative to social gamblers and non-gamblers. When negative life events were further separated into major and minor events, results revealed that problem gamblers reported more major negative life events but not more minor negative life events relative to others. Results indicated that adolescents with gambling-related problems used less task-focused coping, and more avoidance-focused coping. Males, but not females, who experience gambling-related problems reported using more emotion-focused coping strategies. Finally, emotion-oriented coping was found to mediate the relationship between negative life events and gambling severity. Implications and directions for future research are discussed.

Young Adult Gambling Behaviors and their Relationship with the Persistence of ADHD

Young adulthood is a period renowned for engagement in impulsive and risky behaviors, including gambling. There are some indications that young adults exhibit higher gambling rates in comparison to older adults. Problem gambling has also been linked to ADHD. This longitudinal study examines the relationship between gambling and ADHD among an epidemiological sample of young adults (n = 235; males = 179, females = 56) aged 18-24. Results indicate that individuals who report childhood ADHD symptoms which persist into young adulthood experience greater gambling problem severity than participants with no ADHD or those with non-persistent ADHD.     

Gambling Behaviour and the Prevalence of Gambling Problems in Adult EGM Gamblers when EGMs are Banned. A Natural Experiment

In this article, findings of a panel study among former EGM gamblers are discussed. The data were collected in two waves during 2007, and 1293 people, 18 years or older, participated. The background for the study was the Norwegian ban on EGMs from 1 July 2007, and the aim was to investigate how this ban affected gambling involvement and problem levels in the sample. The analysis shows that gambling participation, gambling frequencies and gambling problems were reduced after EGMs disappeared from the market. There was no indication of the development of an illegal EGM market, or of substitution of EGMs with other types of gambling. A reduction in other types of gambling is interpreted as an indication of synergetic effects between games. Reduced gambling participation among the most active EGM gamblers, and among risk gamblers, shows that the reductions in gambling availability had an effect even on highly involved gamblers.     

Reliability and Validity of the Pathological Gambling Adaptation of the Yale-Brown Obsessive-Compulsive Scale (PG-YBOCS)

The Yale Brown Obsessive Compulsive Scale adapted for Pathological Gambling (PG-YBOCS) was developed to measure the severity and change in severity of pathological gambling symptoms. The PG-YBOCS is a 10-item clinician-administered questionnaire that measures the severity of PG over a recent time interval (usually within the past one/two week(s)). In order to assess and validate the scale, it was administered to 337 subjects: 188 pathological gamblers and 149 healthy controls. Internal consistency and correlations between individual items and total score were assessed for various permutations of the sample. Other scales were administered to assess convergent, discriminant and content validity. Sensitivity to change was evaluated in treatment studies with fluovoxamine, lithium, and valproate. Each item was frequently endorsed across a range of severity. Good inter-rater reliability and internal consistency were obtained. The PG-YBOCS showed high validity and reliability for total score, item-total correlations, and for each subscale (Thoughts/Urges and Behavior). PG-YBOCS scores correlated with global severity and South Oaks Gambling Screen (SOGS) scores. The scale was also sensitive to change in pathological gambling severity. PG-YBOCS thus appears to be a reliable and valid measure of pathological gambling severity, and can be regarded as an important tool for clinicians and researchers treating pathological gamblers.     

Prevalence Estimates of Adolescent Gambling: A Comparison of the SOGS-RA, DSM-IV-J, and the GA 20 Questions

Concerns over the rising prevalence of adolescent gambling problems have become more commonplace. A recent meta analysis of studies examining adolescent prevalence rates by Shaffer and Hall (1996) has suggested that between 77–83% of adolescents are engaging in some form of gambling behavior with between 9.9% and 14.2% of youth remaining at risk for a serious gambling problem. Their results further suggest that between 4.4% and 7.4% of adolescents exhibit serious adverse gambling related problems and/or pathological gambling behavior. Comparisons of studies are often difficult due to the use of alternative measures, differing classification schemes, and nomenclature. The present study examined the gambling behaviors of 980 adolescents who were administered three screening measures used with adolescents; the SOGS-RA, DSM-IV-J, and the GA 20 Questions. The DSM-IV-J was found to be the most conservative measure identifying 3.4% of the population as problem/pathological gamblers while the SOGS-GA identified 5.3% and the GA 20 Questions identified 6% of youth as experiencing serious gambling problems. The degree of concordance amongst the measures, gender differences, and classification systems are discussed.     

Validation of the Chinese Version of the Gambling Related Cognitions Scale (GRCS-C)

Gambling cognitions have constantly been associated with the development and maintenance of problem gambling. Despite researchers reporting high rates of gambling and problem gambling among the Chinese, little is known about the role of gambling cognitions among Chinese individuals (Raylu & Oei, 2004a). This is partly because there is a lack of validated instruments to assess gambling cognitions in this population. Thus, the purpose of the present study was to examine and validate the Gambling Related Cognitions Scale-Chinese version (GRCS-C), which was based on the 23-item Gambling Related Cognitions Scale (GRCS; Raylu & Oei, 2004b). Confirmatory Factory Analysis (CFA) using 422 Chinese participants (166 Male, 256 Female; Mean age = 32.28 years) from the general community (221 living in Australia and 201 living in Taiwan) confirmed that a five-factor model was a good fit for the data. The Cronbach’s alpha coefficient for the overall scale was .95, and ranged from .83 to .89 for the five factors. Concurrent, discriminant, and predictive validities of the GRCS (Chinese version) were also good suggesting that the GRCS-C is a valid and reliable instrument for assessing gambling cognitions among non-clinical Chinese samples.     

Development and validation of the Protective Gambling Beliefs Scale (PGBS)

This article aimed to develop and validate a measure of protective beliefs – distinct from the absence of erroneous beliefs – that may be associated with resistance to gambling problems. Study 1 was designed to determine the reliability and content validity of a preliminary set of protective belief items. Participants (N = 1479, 813 males) also completed the Problem Gambling Severity Index (PGSI). Most items were associated with reduced risk of problems; however, items relating to an awareness of gambling harm, and preparedness to lose money were positively correlated with gambling problems and were therefore not demonstrably protective. Study 2 sought to reduce scale size and assess the scale’s ability to predict risk of gambling problems. Participants (N = 1168, 625 males) completed belief items, the PGSI, and measures of gambling consumption and cognitive distortions. Results showed that endorsement of protective beliefs was negatively correlated with PGSI, gambling consumption and cognitive distortions, and predicted PGSI above that of cognitive distortions. Findings suggest that the Protective Gambling Beliefs Scale (PGBS) offers a unique tool for understanding resistance to the development of gambling problems. Future research should focus on exploring whether protective beliefs can diminish the likelihood of the onset of problem gambling.     

Reliability of the JobFit System Pre-Employment Functional Assessment Tool

Functional capacity testing in the pre-employment or post-offer phase of recruitment is increasing in popularity as a preventative tool for controlling sprains and strains in the workplace. The purpose of this study is to determine the reliability of the JobFit System Pre-Employment Functional Assessment (PEFA) as a whole, or in parts, as a precursor for a validity study investigating the relationship between PEFA results and workplace injury rates and severity. A group of 28 healthy male coal mine employees were videotaped whilst they participated in a generic JobFit System Pre-Employment Functional Assessment (PEFA) including tests of aerobic physical fitness, balance, postural tolerances and material handling tolerances. Twenty participants performed a second trial. The test component scores and overall PEFA scores were compared between trials (test-retest, intra-rater) and assessors (inter-rater) to determine their reliability expressed in terms of ICC. Using an ICC score of > 0.75 as good and > 0.90 as excellent, in conjunction with percentage agreement a good to excellent reliability rating was allocated to the overall PEFA score, floor to bench lift, bench to overhead lift, bilateral carry and climbing. A moderate to good rating was recorded for bench to shoulder lifts, reaching forward, reaching overhead and stooping. A poor to moderate rating was recorded for squatting, balance and fitness tests. Test-retest scores were typically lower than intra-tester and inter-tester scores. ICC scores should be interpreted with consideration of their limitations and in conjunction with the actual test results.     

A Cognitive Neuroscience Approach to Studying the Role of Overconfidence in Problem Gambling

Research on the neural correlates of decision making in gambling tasks may be informative for understanding problem gambling. The present study explored confidence and overconfidence using magnetoencephalography (MEG) to measure brain activity during a judgment task. Nineteen undergraduates who self-identified as frequent gamblers (average age 19.7 years; 5 females, 14 males) participated in this study. Participants first completed the DIGS (Winters, Specker & Stinchfield, 2002), a measure of gambling pathology. They then engaged in a behavioral task of confidence assessment, wherein they answered two-alternative trivia questions and estimated the probability that each answer was correct. In a subsequent MEG task, they viewed the questions and a target answer, and indicated with a button press whether the target matched the correct answer. Confidence was directly related to activity in the right prefrontal cortex. Matching and mismatching targets were associated with activity in the medial occipital cortex and left supramarginal gyrus, respectively. An interaction of pathology and match/mismatch was observed in the right inferior occipital-temporal junction region, showing more activity following a mismatch in non-problem gamblers, but not in problem gamblers. Implications of the results for understanding of top–down modulation and attentional systems are discussed in relation to gambling behavior.     

Toward an Animal Model of Gambling: Delay Discounting and the Allure of Unpredictable Outcomes

Laboratory investigations of gambling are sometimes criticized as lacking ecological validity because the stakes wagered by human subjects are not real or no real monetary losses are experienced. These problems may be partially addressed by studying gambling in laboratory animals. Toward this end, data are summarized which demonstrate that laboratory animals will work substantially harder and prefer to work under gambling-like schedules of reinforcement in which the number of responses per win is unpredictable. These findings are consistent with a delay discounting model of gambling which holds that rewards obtained following unpredictable delays are more valuable than rewards obtained following predictable delays. According to the delay discounting model, individuals that discount delayed rewards at a high rate (like pathological gamblers) perceive unpredictably delayed rewards to be of substantially greater value than predictable rewards. The reviewed findings and empirical model support the utility of studying animal behavior as an ecologically valid first-approximation of human gambling.     

The Four Es 1-Year Later: A Tool for Predicting the Development of Gambling Problems

The Four Es is a 40-item scale measuring psychological risk for the development of problem gambling behavior. One-year follow-up interviews (n = 395) from a previously reported phone survey in Queensland, Australia (n = 2,577) (Rockloff & Dyer, 2006) tested the ability of the Four Es instrument to prospectively identify persons who would later develop gambling problems. Two groups of participants were selected for the 1-year follow-up interviews, including (1) persons who had gambling problems, high-risk alcohol abuse problems, and/or substance abuse problems (abuse group); and (2) a random selection of other persons from the original survey (random group). The results indicated that the “Excess” trait, which measures impulsive behavior, was predictive of relative increases in gambling problems for both groups over the 1-year period. Additionally, the Four Es questionnaire showed good psychometric properties in the surveys, with a test-retest reliability of r = .70 and a Cronbach’s alpha reliability of α = .90 and .92 in the original and follow-up interviews, respectively.     

An Experiment on the Social Facilitation of Gambling Behavior

Research and theory regarding the social facilitation effect generates the expectation that the presence of other gamblers (or co-actors) in a gaming venue is likely to intensify individual gambling behavior and magnify losses. Fifty male and 66 female participants (116 total) played a computer-simulated electronic gaming machine with a fixed winning sequence, followed by an indefinite losing sequence. Measures of the intensity of gambling behavior included the final payout (a direct measure of losses), average bet-size, number of trials played, and the speed of play. Some participants received false feedback from the computer designed to suggest that other gamers in adjacent rooms were playing and sometimes winning at the same game. Persons who received both sight and sound information, including winning bells and instant messages regarding the wins of other (fake) players, placed more bets and lost more money compared to the other conditions with less information.     

Exploring the Hidden Nature of Gambling Problems among People Who Are Homeless

Abstract

Although people with gambling problems are now recognised to be among those groups of people at increased risk of homelessness, little research has explored their experiences. This qualitative interpretive study explored the experiences of people who were homeless and had gambling problems, and the housing and gambling service providers assisting them. In-depth interviews were conducted with 17 service users and 18 service providers. A key finding was that gambling problems among those experiencing homelessness are often hidden; few people presented to housing services admitting to gambling problems. Shame, stigma, and identity issues were described as the main reasons service users did not disclose their gambling activities. The research highlighted that the relationship between service providers and service users was infused with power imbalances and shaped by social discourses and policies that demand self-responsibility and hinder information sharing between service providers and service users.
