This study tested whether alcohol increases behaviors associated with video lottery terminal (VLT) play, particularly among probable pathological gamblers. Forty-four regular VLT players were designated either probable pathological gamblers or non-pathological gamblers on the basis of scores on the South Oaks Gambling Screen (SOGS); [Lesieur & Blume (1997). American Journal of Psychiatry, 144, 1184-1188] Gamblers from each SOGS category were randomly assigned to either a moderately intoxicating alcohol dose or a control beverage condition (n = 11 per cell in the 2 x 2 between-subjects design). Following beverage consumption and absorption, participants played a video poker VLT game for up to 30 minutes. Four behaviors were measured: "power-bets" (doubling bet after viewing only two cards of the five-card poker hand); total money spent; mean bet magnitude; and number of minutes played. Alcohol increased time spent playing and rate of power-bets, particular among the probable pathological gamblers. Post hoc analyses revealed that alcohol also influenced the proportion of losing hands played--increasing them among the probable pathological gamblers while decreasing them among the non-pathological gamblers. Clinical and policy implications of the findings are discussed.

This study explored the factor structure of the Gambling Motives Questionnaire (GMQ) with a large stratified sample of 839 moderate gamblers (49% female; median age category = 45–54 years) and examined the effect of including a monetary motive item on GMQ factor structure. Participants responded to a telephone survey in which they were asked how often they gamble for each of 16 reasons, including the 15 GMQ motives and an additional motive: “to win money”. Exploratory principal components analysis of the 15 GMQ items revealed three factors, together accounting for 49.04% of the total variance in GMQ scores. The factors tapped enhancement, coping and social motives, although only the coping subscale displayed strong internal consistency. A second exploratory principal components analysis of the 15 GMQ items and the monetary motive item continued to reveal three factors tapping enhancement, coping and social motives. The addition of the monetary motive item strengthened the independence of the components and dramatically improved the internal consistency of the enhancement factor. The results suggest that the psychometric properties of the GMQ, when used with a population of moderate gamblers, may be considerably strengthened with only minor modifications.

People frequently combine alcohol use and gambling. However, our understanding of the effects of alcohol on gambling behavior is limited, both in terms of what the effects are and how they occur. The effects of a moderately intoxicating dose of alcohol (i.e., a blood alcohol concentration of .06 g%) on the video lottery terminal (VLT) gambling behaviors and cognitions of community-recruited nonpathological (n = 30) and probable pathological gamblers (n = 30) were compared. Alcohol increased the rate of double up betting (i.e., choosing to play a bonus game, after a winning video poker hand, which involves trying to pick a higher ranked card than the dealer's card from among 5 face down cards) of probable pathological gamblers, but did not influence their irrational beliefs about VLT play. Alcohol maintained the irrational beliefs about VLT play of nonpathological gamblers, but did not influence their gambling behaviors. Results are consistent with a growing body of research finding that gambling cognitions have an equivocal role in explaining actual gambling behaviors. Potential mechanisms for the observed effects are discussed. Applied implications discussed include: educating regular VLT players about the effects of alcohol on irrational gambling cognitions; reconsidering policies and practices that make alcohol available where machine gambling takes place; and targeting even moderate alcohol use in the treatment of gambling problems.

Disordered gambling in young adults is hypothesized as being related to mistaken gambling-related cognitions. Few studies have examined the temporal order of this relationship using longitudinal data. The purpose of this study is to understand the directionality of the relationship between gambling cognitions and gambling severity in a longitudinal sample of young adults. Young adults (N = 578), initially aged 18–21 years, completed the Manitoba Longitudinal Survey of Young Adults at two time points approximately 2–3 years apart. Measures of beliefs about randomness related to gambling and gambling severity, as measured by the Problem Gambling Severity Index, were utilized. A cross-sectional relationship between gambling severity and gambling-related cognitions was observed with greater gambling severity being associated with increased endorsement of mistaken cognitions. Evidence for a bidirectional longitudinal relationship was observed with faulty gambling cognitions leading to later problematic gambling behaviors and vice versa when examining a total beliefs scale. When examining specific beliefs about randomness, initial gambling group membership predicted later endorsement of certain beliefs about randomness while initial belief ratings did not impact later gambling group membership. The results of this study suggest a bidirectional relationship between gambling severity and erroneous gambling-related cognitions. However, when examining specific beliefs about randomness, evidence was found for problem gambling behaviors leading to erroneous gambling beliefs. These findings suggest that prevention efforts targeting cognitions may not be as effective in impacting those not yet demonstrating disordered gambling behaviors.

Background and aims: Despite increases in female gambling, little research investigates female-specific factors affecting gambling behavior (GB). Although research suggests that some addictive behaviors may fluctuate across menstrual cycle phase (MCP), gambling requires further investigation. In two studies, we examined associations between MCP and three risky GBs: time spent gambling, money spent gambling, and the probability of consuming alcohol while gambling. Associations between MCP and negative affect were also examined in Study 2. We predicted that, consistent with self-medication theory, increases in negative affect (Study 2) and risky GBs (Studies 1 and 2) would occur premenstrually/menstrually relative to other phases. Methods: Data were obtained from 33 female gamblers using a retrospective timeline followback procedure (Study 1) and from 20 female gamblers using a prospective 32-day, daily diary method (Study 2). In Study 2, salivary progesterone levels verified self-reported MCP validity. Results: Findings revealed significant, but somewhat inconsistent, MCP effects on GBs across studies. The self-medication hypothesis was partially supported. Increases relative to another MCP(s) were found for alcohol consumption while gambling premenstrually, time spent gambling menstrually/premenstrually, money spent gambling menstrually, and negative affect premenstrually. Unexpectedly, findings more consistently indicated that GBs increased during ovulation, suggestive of enhanced reward sensitivity. Progesterone assays validated selfreported MCP (Study 2). Discussion and conclusions: The results suggest a role of ovarian hormones on negative affect and GBs in females. This research could lead to the identification of female-specific factors affecting gambling and the development of more effective interventions for females with, or at risk for, problematic gambling.
