“…If we ignore the false negatives in our research, our study shows that a cut-point of 8 produces 77% sensitivity, which is not unlike the 77% and 62% reported against clinical interview and SOGS measures respectively (Ferris & Wynne, 2001b). On the other hand, the cut score of 5.5 that we find to be optimally predictive for clinical assessment is relatively close to the cut score of 5 found by Williams and Volberg (2013) for a large Ontario sample. Williams and Volberg (2013) did not perform categorical, dimensional or ROC analyses on their sample as we do.…”

The Problem Gambling Severity Index, the scored module of the Canadian Problem Gambling Index, is a population-based survey instrument that is becoming the preferred epidemiological tool for estimating the prevalence of disordered gambling. While some validation evidence for the Problem Gambling Severity Index is available, very little is known about its psychometric characteristics in developing countries or in countries the populations of which are not highly Westernised. The aim of this study was to investigate the validity of the Problem Gambling Severity Index with a specific focus on its criterion-related and construct (concurrent) validity in a community sample of gamblers in South Africa (n = 127). To this end, the Problem Gambling Severity Index was administered alongside the Diagnostic Interview for Gambling Severity and measures known to associate with gambling severity (impulsivity, current debt, social problems, financial loss, race, sex). Results showed that the Problem Gambling Severity Index was predictive of Diagnostic Interview for Gambling Severity diagnosis from both a categorical and dimensional point of view and demonstrated high discrimination accuracy for subjects with problem gambling. Analysis of sensitivity and specificity at different cut-points suggests that a slightly lower Problem Gambling Severity Index score may be used as a screening cut-off for problem gambling among

“…The SOGS has weak predictive power of some problem gamblers; however, these criticisms are also true for other widely used measures of problem and pathological gambling, including the CPGI and the NODS (Williams & Volberg, 2014). The poor predictive power of gambling measures appears to be a result of divergent interpretations of concept operationalization and has implications for the sensitivity of distinguishing between non-problem, some problem, and probable pathological gambling in the current study.…”

The Influence of Locus of Control and Sensation Seeking Among Undergraduate Texas Hold’em Players

Texas Hold'em poker has become increasingly popular on university and college campuses. However, not much is known about personality correlates of engaging in Hold'em, which is commonly seen as more skill-based compared to other forms of gambling. The current study sought to determine where, how much, and which students are playing Hold'em, and to further distinguish these patterns among gamblers. The current study describes Canadian university students' Hold'em-specific behaviour and beliefs, as well as determines whether locus of control and sensation seeking traits independently correlate with and predict gambling behaviour among a university sample. Undergraduate students (N = 96) completed an online questionnaire containing Rotter's Internality-Externality scale (I-E), the Zuckerman Sensation Seeking Scale (SSS) and the South Oaks Gambling Screen (SOGS). Participants played a round of Hold'em in lab and answered a survey about their perception of Hold'em and of the game they played. Sensation seeking and external locus of control were significantly positively correlated with gambling pathology. Participants overestimated the number of hands played and the time spent playing Hold'em. There was a significant positive correlation between gambling pathology and gambling success. The I-E and boredom susceptibility sensation seeking subscale significantly predicts some problem/pathological gambling. The current study suggests that more pathological gamblers display higher levels of sensation seeking and a more external locus of control than nonproblem gamblers, and that the type of gambling activity and setting in which gambling occurs should be considered in future research looking at personality characteristics of certain problem/pathological gamblers.

“…Clearly, the estimated rate of current pathological gambling is highly dependent on the instrument used. This was also the conclusion of Williams and Volberg (2010), who systematically examined the methodology of gambling surveys.…”

Gambling and Problem Gambling in the United States: Changes Between 1999 and 2013

et al. 2014

Telephone surveys of U.S. adults were conducted in 1999-2000 and again in 2011-2013. The same questions and methods were used so as to make the surveys comparable. There was a reduction in percentage of past-year gambling and in frequency of gambling. Rates of problem gambling remained stable. Lottery was included among the specific types of gambling for which past year participation and frequency of play declined. Internet gambling was the only form of gambling for which the past-year participation rate increased. The average win/loss increased for several forms of gambling, providing a modest indication that gamblers were betting more, albeit less frequently. Between the two surveys, the rates of past-year participation in gambling declined markedly for young adults. In both surveys, rates of problem gambling were higher for males than females, and this difference increased markedly between surveys as problem gambling rates increased for males and decreased for females. For the combined surveys, rates of problem gambling were highest for blacks and Hispanics and lowest for whites and Asians. In both surveys, the rates of problem gambling declined as socio-economic status became higher. Possible explanations for these trends are discussed.
