Prevalence of pathological gambling and related problems among college students in the Quebec metropolitan area

Dopamine activity in the nigrostriatal pathway alters cue-induced risky choice patterns in female rats

Deficits in cost/benefit decision making is a critical risk factor for gambling disorder. Reward-paired cues may play an important role, as these stimuli can enhance risk preference in rats. Despite extensive research implicating the dorsal striatum in the compulsive aspects of addiction, the role of nigrostriatal dopaminergic activity in cue-induced risk preference remains unclear, particularly in females. Accordingly, we examined the effects of manipulating the dopaminergic nigrostriatal pathway on cue-induced risky choice in female rats. TH:Cre rats were trained on the cued version of the rat Gambling Task. This task was designed such that maximal reward is attained by avoiding the high-risk, high-reward options and instead favouring the options associated with lower per-trial gains, as they feature less frequent and shorter time-out penalties. Adding reward-paired audiovisual cues to the task leads to greater risky choice on average. To assess the role of the nigrostriatal pathway, a viral vector carrying either Cre-dependent inhibitory or excitatory DREADD was infused into the substantia nigra. Rats then received clozapine-N-oxide either during task acquisition or after a stable performance baseline was reached. Inhibition of this pathway accelerated the development of risk preference in early sessions and increased risky choice during performance, but long-term inhibition actually improved decision making. Activation of this pathway had minimal effects. These results provide evidence for the involvement of the dopaminergic nigrostriatal pathway in cue-induced risk preference in females, therefore shedding light on its role in cost/benefit decision-making deficits and expanding our knowledge of the female dopaminergic system.

Neuropsychiatric Aspects of Impulse Control Disorders

Impulse control disorders (ICDs) are neuropsychiatric conditions characterized by the repeated inability to resist an impulse, drive, or temptation to perform an act that is harmful to the person or others. Although classification approaches to ICDs vary both diachronically and synchronically, this group of conditions encompasses a wide range of syndromes, including pathologic gambling, kleptomania, trichotillomania, excoriation (skin picking) disorder, intermittent explosive disorder, pyromania, oppositional defiant, conduct, and antisocial personality disorders. ICDs can play a significant role as comorbidities in both neurodevelopmental (eg, attention-deficit/hyperactivity disorder, Tourette syndrome) and neurodegenerative (eg, Parkinson disease) disorders.

Gambling involvement and problem gambling correlates among European adolescents: results from the European Network for Addictive Behavior study

PURPOSE

Worldwide, concern has grown over the expansion of gambling among adolescents, who have an increased likelihood of developing risk-taking behaviors. This study aimed to increase knowledge of problem gambling among adolescents in seven European countries and to assess the effect of demographic and lifestyle factors recorded in the European Network for Addictive Behavior survey (https://www.eunetadb.eu).

METHODS

A cross-sectional school-based study (n = 13,284) was conducted in Germany, Greece, Iceland, The Netherlands, Poland, Romania and Spain. Anonymous self-completed questionnaires included socio-demographic data, internet usage characteristics, school achievement, parental control, the Internet Addiction Test, the South Oaks Gambling Screen-Revised for Adolescents Test and Achenbach's Youth Self-Report.

RESULTS

12.5% of the participants reported last year gambling activities either online or offline. 3.6% of the study participants and 28.1% of gamblers (either online or offline) were at risk or had a gambling problem. The study results showed that a higher proportion of adolescents was either at risk or had a gambling problem among males, in the older age group, when the parental educational level was lower/middle, and in the absence of siblings. Furthermore, being at risk or having a gambling problem was associated with lower age at first use of the internet, lower school grades, using the internet 6-7 days per week, and problematic internet use. At risk or problem gamblers had higher scores on all scales of problem behavior and lower scores (lower competence) on activities and academic performance.

CONCLUSIONS

Our findings underline the need for better gambling legislation and suggest the importance of developing social responsibility tools that may help diminish adolescent gambling involvement, with special attention to males.

A Meta-analytical Synthesis and Examination of Pathological and Problem Gambling Rates and Associated Moderators Among College Students, 1987-2016

The problem of gambling addiction is especially noteworthy among college students, many of whom have the resources, proximity, free time, and desire to become involved in the myriad options of gambling now available. Although limited attention has been paid specifically to college student gambling in the body of literature, there have been three published meta-analyses estimating the prevalence of probable pathological gambling among college students. The research presented is the largest and most comprehensive, presenting an up-to-date proportion of those students worldwide exhibiting gambling pathology as assessed by the South Oaks Gambling Screen, and is the first to include estimates of sub-clinical problem gambling. A thorough literature review and coding procedure resulted in 124 independent data estimates retrieved from 72 studies conducted between 1987 and the present, surveying 41,989 university students worldwide. The estimated proportion of probable pathological gamblers among students was computed at 6.13%, while the rate of problem gambling was computed at 10.23%. Statistical significance was found in the influence of the percentage of non-white students on pathological gambling rates. The implications of this and other moderator analyses such as age and year of studies, as well as recommendations for future practice in dealing with college students and gambling disorder on campus are outlined and described in detail. Suggestions and rationales for future avenues of research in the area are also described.

Racial and Ethnic Differences in Problem Gambling among College Students

The college years are a formative period where the risk for development of problematic gambling is high. Research examining racial and ethnic differences in gambling behaviors has been limited and inconsistent. The aims of this study were to examine racial and ethnic differences in problem gambling among a large sample of college students. Undergraduates (N = 3058) from a large southern university completed an online screening questionnaire which included demographics, gambling frequency, gambling expenditure (i.e. money lost) in the previous 6 months, and the South Oaks Gambling Screen (SOGS). Negative binomial regression results indicated that Asian participants gambled less frequently than participants who were Caucasian or Hispanic/Latino(a), but spent more money than participants who were African-American (AA)/Black or Hispanic/Latino(a). A significantly larger proportion of Asian students met probable pathological gambling criteria (SOGS 5+; 7.8 %) and at-risk gambling criteria (SOGS 3+; 16.3 %)) than Caucasian (5.2; 10.1 %), AA/Black (3.9; 10.2 %), or Hispanic/Latino(a) (3.6; 9.4 %) students. Additionally, a significantly larger proportion of Asian students endorsed problematic gambling indicators such as lying about losses, feeling guilty about gambling, feeling like they had a gambling problem, being criticized for their gambling, feeling like they couldn't stop gambling, losing time from school or work due to gambling, having a family history of problem gambling, and arguing with close others about their gambling than Caucasian, AA/Black or Hispanic/Latino(a) students. Results suggest that Asian students may be a high-risk sub-group of college gamblers, and that there is a critical need for targeted interventions for this population.

Confirmatory factor analysis of the Spanish version of the Gamblers' Beliefs Questionnaire in a sample of Argentinean gamblers

INTRODUCTION

Cognitive distortions are related to gambling frequency and gambling severity. Having a culturally sensitive measure to assess cognitive distortions will facilitate the early detection of people who might be at risk of developing problematic gambling behaviors. The Gamblers' Beliefs Questionnaire was translated into Spanish (GBQ-S) but no previous study explored the structure of the GBQ-S in a non-US sample with different levels of gambling involvement.

AIM

The present study examined the factor structure of the GBQ-S in a community sample of gamblers from Argentina. It also analyzed the association between cognitive distortions and type of gambling activity and frequency of gambling behaviors and the predictive utility of the GBQ-S on gambling severity.

PARTICIPANTS

508 youth and adults completed the GBQ-S.

RESULTS

The CFA showed an overall acceptable fit to the data confirming the proposed two-factor model. Scores of the two GBQ sub-scales were positively and significantly correlated with scores on gambling severity. Cognitive distortions have a significant effect on gambling severity after controlling for frequency of engagement in gambling activities. Luck and perseverance, but not illusion of control, was positively related to gambling severity.

DISCUSSION

scores measured by the GBQ-S exhibit adequate psychometric properties for the accurate assessment of cognitive distortions across adults and youth from the general community of Argentina.

Treatment of Pathological Gambling Using a Guided Self-Change Approach

Pathological gamblers are prone to leave treatment early and often display low levels of motivation within treatment. Use of brief treatments that emphasize reducing client ambivalence through motivational techniques may help increase the likelihood of treatment compliance. This case study describes a 5-session treatment of pathological gambling using a brief and motivationally focused cognitive—behavioral guided self-change (GSC) approach. The 36-year-old gambler in this study was treated for pathological gambling. At 1-month and 6-month follow-ups, the individual evidenced significant improvement in symptoms of pathological gambling. The client also showed considerable reductions in gambling behaviors including number of gambling episodes, length of time spent gambling, and amount of money wagered. These results support use of the GSC approach in treating pathological gamblers.

Development and validation of the gambling problems scale

The purpose of the present study was to examine the initial psychometric properties of the Gambling Problems Scale (GPS), developed for the college student population. Participants were college students recruited for an ongoing larger clinical trial from a Midwestern university who reported gambling in the past 60 days and who were experiencing gambling-related problems, scoring +3 on the South Oaks Gambling Screen or +1 on the Brief Biopsychosocial Gambling Index (N = 334). Factor analyses and reliability analyses were conducted to examine the validity of score interpretation and the reliability of scores for the measure. Results suggested a 16-item unidimensional measure provided the best parsimony and theoretical fit. Examination of concurrent and incremental validity of scores provided additional support for the psychometric properties of the GPS. The GPS may be a useful tool for researchers and clinicians interested in examining gambling-related problems among college students and other young adults.

Suicidal events among pathological gamblers: the role of comorbidity of axis I and axis II disorders

The risk for suicidal ideation and suicide attempts among pathological gamblers is high compared to the general population. Little is known about the interplay of Axis I and Axis II disorders, severity of gambling disorder, and suicidal ideation and suicide attempts. The study aims to address this linkage. The sampling design of the study "Pathological Gambling and Epidemiology" (PAGE) included four recruitment channels: general population, gambling locations, project telephone hotline, and in-patient treatment for pathological gambling. A total of 442 study participants with lifetime pathological gambling received a clinical interview. The multivariate analysis showed mood disorders (Relative Risk Ratio, RRR=5.14, 95%-Confidence Interval, CI=2.91-9.07), substance use disorders (RRR=1.73, CI=1.02-2.94), and early onset of gambling disorder (RRR=0.96, CI=0.93-0.99) to be associated with suicidal ideation. Suicidal attempts were associated with female sex (RRR=3.58, CI=1.56-8.19), mood disorders (RRR=11.92, CI=4.70-30.26), and Cluster B personality disorders (RRR=2.40, CI=1.13-5.10). Among study participants with suicide attempts, more had a Cluster B personality disorder than among participants with ideation solely (RRR=3.08, CI=1.48-6.40). Among this large mixed sample of pathological gamblers, high proportions of individuals with suicidal events, multi-morbidity on Axis I, and a strong linkage to Cluster B personality disorders were found.

Disordered gambling and co-morbidity of psychiatric disorders among college students: an examination of problem drinking, anxiety and depression

We assessed the occurrence of co-morbid psychiatric disorders (i.e., problem drinking, anxiety, and depression) among college students who met the threshold for disordered gambling. The participants included a large sample of undergraduate students (n = 1,430) who were enrolled in an introductory health course at a large, southeastern university in Spring 2011 and completed an online assessment that included scales to assess disordered gambling, problem drinking, anxiety, and depression. We calculated screening scores, computed prevalence rates for each disorder, and calculated Pearson correlations and Chi square tests to examine correlations and co-morbid relationships between the four disorders. Analyses indicated that all disorders were significantly associated (p < .01) except for disordered gambling and anxiety. Because college students who experience disordered gambling (and other psychiatric disorders) are at increased risk of experiencing co-occurring disorders, it might be useful for college health professionals to concurrently screen and intervene for co-occurring disorders.

Decision-making after continuous wins or losses in a randomized guessing task: implications for how the prior selection results affect subsequent decision-making

Background

Human decision-making is often affected by prior selections and their outcomes, even in situations where decisions are independent and outcomes are unpredictable.

Methods

In this study, we created a task that simulated real-life non-strategic gambling to examine the effect of prior outcomes on subsequent decisions in a group of male college students.

Results

Behavioral performance showed that participants needed more time to react after continuous losses (LOSS) than continuous wins (WIN) and discontinuous outcomes (CONTROL). In addition, participants were more likely to repeat their selections in both WIN and LOSS conditions. Functional MRI data revealed that decisions in WINs were associated with increased activation in the mesolimbic pathway, but decreased activation in the inferior frontal gyrus relative to LOSS. Increased prefrontal cortical activation was observed during LOSS relative to WIN and CONTROL conditions.

Conclusion

Taken together, the behavioral and neuroimaging findings suggest that participants tended to repeat previous selections during LOSS trials, a pattern resembling the gambler’s fallacy. However, during WIN trials, participants tended to follow their previous lucky decisions, like the ‘hot hand’ fallacy.

Self-identification as a moderator of the relationship between gambling-related perceived norms and gambling behavior

This research was designed to evaluate social influences and perceived social norms on gambling behavior among undergraduate students. Furthermore, this research was designed to replicate and extend previous research demonstrating that young adults overestimate the prevalence of gambling among peers, and that the magnitude of overestimation is positively associated with own use (Larimer and Neighbors, Psychol Addict Behav 17:235-243, 2003). We expected that; (1) gambling college students would identify more strongly with other gambling students compared to other students in general; (2) identification with other gambling students would predict gambling behaviors over and above perceived prevalence of gambling; and (3) identification with other gambling students would moderate the association between perceived social norms and gambling behavior. Participants included 1,486 undergraduate students who completed measures assessing gambling quantity and frequency, gambling-related perceived descriptive norms, and identification with groups. Results revealed that perceived norms for gambling were associated with gambling and revealed that students identified more strongly with other students than either gamblers or student gamblers. However, gambling behavior was more strongly associated with identification with gambling students than students in general. There was consistent support for the perspective that social identity moderates the association between perceived norms for gambling and gambling behavior. This research builds on previous examinations of social influences related to gambling and suggests that it may be important to consider the overall prevalence of a given behavior before considering norms-based intervention approaches. Interventions utilizing social norms for gambling may be advised to consider references other than just the typical student.

Jeux de hasard et d'argent chez les adolescents en centre jeunesse : comparaison en fonction des lois

Adolescents under the care of Youth centers present with many risk factors related to the development of pathological gambling. This study describes gambling habits of participants under the Young Offenders Act (YOA) and participants under the Youth Protection Act (YPA), and compare these gambling habits to those of high school teenagers. Face to face interviews were conducted with 74 adolescents from two youth centers in Quebec, Canada. Results show that YOA adolescents report different gambling habits than YPA participants. The YOA adolescents constitute a subgroup at risk of developing gambling problems. Further, adolescents perceive that their time spent in Youth centers has almost no impact on their gambling habits. Findings illustrate the importance to create a prevention program targeting adolescents under the care of Youth centers.

Online Poker Gambling Among University Students: Risky Endeavour or Harmless Pastime?

This study aims to describe online poker gambling patterns and associated problems in a representative sample of university students. The study sample consisted of 366 past-year online and offline poker gamblers and was drawn from a larger survey sample of full-time undergraduate students (N=2,139) randomly selected across four university campuses in Montreal, Canada. The questionnaire included self-reported measures of poker gambling patterns and problems, negative consequences of gambling, drinking problems, and illicit drug use. Online poker was found to be associated with problem gambling, over-spending and debt, as well as problems with university studies, interpersonal relationships, and illicit drug use. Given the propensity of university students to adopt risky behaviours, on-campus prevention programs are warranted in the midst of the online poker craze, especially given that online gambling remains unregulated. Detection tools should be available for students to recognize critical shifts in their gambling habits from a leisure activity to a risky endeavour.

A developmental perspective of gambling behavior in children and adolescents

Although it has been determined that gambling is a popular activity amongst the young, there seems to be a lack of studies examining developmental differences in children's gambling behavior. This study examines developmental differences in children's blackjack gambling behavior. One hundred and four students (51 males; 53 females) from grades 4, 6, and 8 completed a questionnaire examining their gambling behavior in general and individually played a computerized blackjack game with the following data being recorded: percentage of accuracy, amounts of money bet, gross winnings, percentage of wins, number of hands played, and end balance. Findings revealed few developmental differences in prevalence and frequency of gambling behavior and performance on a blackjack task. Males were found to wager greater amounts of money and have larger gross winnings than females on the blackjack task. Furthermore, males were more likely to view gambling as involving both large amounts of skill and luck, thus suggesting an illusion of control for gambling activities. The results are discussed from a cognitive developmental perspective.

Gambling among primary school students

This study identifies the gambling behavior of 1,320 primary school students aged 8 to 12 of the 4th, 5th and 6th grades. Eighty-six percent admitted to having, at some time or another, bet money. Lotteries are the most popular form of gambling for this age group. Sixty-one percent of these students gamble with lotteries. In descending order of popularity, other games played by students were: bingo, card-playing for money, bets on sports, wagering on specific events, video gambling (video poker and slot machines), and finally betting on games of skill. Gambling behaviors differed according to gender. More than 40% of respondents reported gambling once a week or more for at least one game. Because of the early development of gambling behavior in children, prevention programs for pathological gambling should be implemented as early as the fourth grade.

Impacts of gambling problems on partners: partners’ interpretations

Partners can be especially vulnerable to the negative effects of gambling problems, but little research has sought to understand partners’ experiences from their own unique perspectives. This qualitative interpretive study explored the impacts of gambling problems on partners. In-depth interviews were conducted with 18 partners and ex-partners of people with gambling problems to understand their experiences of gambling problems from their perspectives. The findings showed that partners experienced a wide range of negative effects, especially on their financial security, their emotional, mental and physical health, and on their relationships. The financial impacts of gambling problems on partners were substantial and far-reaching. Some partners were forced to take up extra employment to cover household expenses and pay off gambling-related debts. Others lost their savings, homes, belongings and established ways of life. While these impacts were extensive, partners also experienced a range of emotional impacts that were equally devastating. Their gambling partner’s lies, dishonesty and concealment of problems and gambling behaviour created considerable distress, loss of trust and a sense of betrayal. These experiences undermined these partners’ sense of self-identity, and created additional conflicts within their relationships. Along with accumulating mental and physical health impacts, these challenges lead to separation and/or divorce for many participants. These findings point to the need for greater understanding of partners’ experiences and public health initiatives that protect partners and their families from the harmful effects of gambling problems.

How is gambling related to perceived parenting style and/or family environment for college students?

Background and aims The relationship between college student gambling, parenting styles, and family environments is a neglected area of gambling research. Do parenting styles indirectly influence problem gambling behaviors via family environments? Do poor family environments, characterized by high levels of conflict and low levels of cohesion, increase the likelihood of problem gambling among youth? This study explored the interrelationships among college students' current gambling behaviors and a) having an emotionally close and supportive family environment, b) having nagging and critical parents, c) having an authoritative mother, and d) frequency of alcohol consumption. Methods and results Survey data were collected from 450 undergraduate students enrolled in introductory psychology classes at two state universities in a southern state. Feeling that one has nagging and critical parents was associated with gambling in more venues, while the opposite was true for having emotionally close and supportive families. However, perceptions of having authoritative mothers were not related to gambling. The results also showed that more frequent alcohol consumption was associated with higher odds of gambling in casinos, playing cards for money, betting on sports, gambling on the Internet, higher gambling losses, and a larger number of gambling venues. Conclusions As with any exploratory research, there are several unique lines of inquiry that can, and should, follow from these findings, including more research on how college students' attitudes toward gambling activities may have begun prior to college and been influenced by their feelings about their homes and parents.

High-stakes gambling: seniors may be the losers

The U.S. government has almost always allowed some limited legal gambling. In recent years, gambling has proliferated and is legal in some form, including racetracks, casinos, lotteries, bingo, and cards, in almost every state. Observational data and anecdotal reports have created concern that gambling rates, and especially rates of problem gambling, are increasing, especially among the elderly. Most research on gambling among the elderly is conducted in casinos, simply because so many elders visit them, and they are now the largest gambling venues in the nation. Risk factors for problem gambling include alcohol or substance abuse, low socioeconomic neighborhood residence, access to gambling opportunities, family and friend acceptance of gambling, and participation in a greater number of gambling types. More than 80% of elders gamble as a social activity and gamble responsibly. However, some elders are problem or pathological gamblers, and are vulnerable to financial instability. Currently, people older than 65 years of age comprise 39% to 45% of casinos' traffic, partly because casinos target this market heavily. Once it becomes clear that gambling is a problem, individuals can receive counseling and interventions such as a 12-step program and cognitive-behavioral therapy. Pharmaceutical interventions are fairly new, but promising.

Prevalence of adolescent problem gambling, related harms and help-seeking behaviours among an Australian population

Epidemiological studies have consistently reported prevalence rates ranging between 0.9 and 23.5% for problem gambling among young people. With such a large range reported in the literature, it is clear that more research in this area would be of value. The current study investigated the prevalence rate of adolescent gambling and problem gambling and explored types of harm-related and help-seeking behaviours associated with gambling specific to this population in an Australian setting. A self-administered battery of questionnaires was distributed to 252 students aged 12-18 years, attending four private schools in the Eastern suburbs of Sydney, Australia. The battery included a self-administered socio-gambling demographic questionnaire, the Diagnostic and Statistical Manual Fourth Edition Multiple Response Juvenile (DSM-IV-MR-J) diagnostic instrument to assess problem gambling status, the Gambling Attitudes Scale, and questionnaires using a Likert scale to measure gambling-related harms and help-seeking behaviours. The prevalence rate among this group was found to be 6.7%. The study found further support for previous findings suggesting that a significant proportion of young people meet criteria for problem gambling, that males are at-risk and that few adolescents are able to recognise when gambling is problematic or access mental health professionals for assistance.

Non-substance-addictive behaviors in youth: pathological gambling and problematic Internet use

Adolescence is characterized by participation in multiple novel and potentially risky behaviors. Amongst these behaviors are gambling and use of the Internet, and excessive engagement in these activities (as seen in pathological gambling and problematic Internet use) may be accompanied by serious impairments in school, mental health, and social functioning. This article reviews the potential impact of pathological gambling and problematic Internet use in youth, the relevance of subsyndromal levels of participation, and how prevention and treatment strategies may be considered and tested within a developmental framework.

Reliability, validity, and cut scores of the south oaks gambling screen (SOGS) for Chinese

We examined the reliability, validity, and classification accuracy of the South Oaks Gambling Screen (SOGS) when adopted for use in Chinese. The DSM-IV criteria for pathological gambling served as the standard against which the classification accuracy of the SOGS was tested. A total of 283 Chinese adults in the community and 94 Chinese treatment-seeking gamblers were recruited. The internal reliability of the SOGS was satisfactory for the general sample and acceptable for the gambling sample. The SOGS was correlated with the DSM-IV criteria items as well as psychosocial and gambling-related problems. Relative to the DSM-IV criteria, the SOGS tended to overestimate the number of pathological gamblers in both samples. In general, we were relatively confident that individuals were not pathological gamblers if the SOGS scores were between 0 and 4 and were pathological gamblers if the SOGS were between 11 and 20. There was about 50–50 chance of being pathological gamblers if the SOGS scores were between 8 and 10. However, the probability of individuals being pathological gamblers was about 0.30 if the SOGS scores were between 5 and 7. We proposed a SOGS cut score of 8 to screen for probable pathological gambling in Chinese societies.

The validity and reliability of four measures of gambling behaviour in a sample of Singapore University students

The primary aim of this study was to determine the reliability and validity of measures for detecting problem gamblers for use with university students in a Singapore context. The four instruments commonly used in gambling research, the DSM-IV, GA-20, SOGS and CPGI were administered to a sample of students (n = 193) from a representative cross section of faculties from one university. The CPGI was found to be the most reliable (alpha = 0.922) and valid in terms of construct validity as demonstrated by factor analysis. Despite being a lengthy instrument it is recommended that future studies such as randomized controlled trials of problem gambling interventions in Singapore adopt a modified version of the CPGI, made simpler and easier to use with fewer items and more appropriate terminology.

Student gambling, erroneous cognitions, and awareness of treatment in Scotland

Rates of probable pathological gambling in colleges and universities across Scotland were investigated with a nationally distributed sample consisting of students (n = 1,483) and members of staff (n = 492). Gambling-related erroneous cognitions (Gambling Beliefs Questionnaire [GBQ]) and gambling severity (South Oaks Gambling Screen [SOGS]) were measured, with additional questions enquiring about awareness of treatments available for gambling problems. Rates of past-year problem and probable pathological gambling for students were 4.0% and 3.9%, respectively. An exploratory factor analysis of the GBQ resulted in a 24-item five-factor model, with gambling severity (as indicated by SOGS scores), indices of increasing gambling involvement (gambling frequency and number of gambling activities), and male gender being positively correlated with higher levels of erroneous cognitions, suggesting erroneous cognitions may not be prominent for females with gambling problems. Less than a fifth of students were aware of where to go to receive help for gambling-related problems.

Disordered gambling among college students: a meta-analytic synthesis

The purpose of this study was to use a meta-analytic procedure to synthesize the rates of disordered gambling for college students that have been reported in the research literature. In order to identify all possible studies that met stringent inclusion criteria, Medline, PsychINFO, and SocioIndex databases were searched with the terms "gambling," and "college student". This process resulted in 15 studies concerning gambling among college students that were published through July 2005. To synthesize the 15 studies, a random effects model for meta-analysis was applied. The estimated proportion of disordered gamblers among college students was 7.89%. This estimate is noteworthy because it is higher than that reported for adolescents, college students or adults in a previous study using meta-analytic procedures with studies conducted prior to 1997.

Excitement-seeking gambling in a nationally representative sample of recreational gamblers

Excitement-seeking and related constructs have been associated with heavier gambling and negative health measures in problem and/or pathological gamblers. Most adults gamble recreationally and an understanding of the relationship between excitement-seeking as a motivation for gambling amongst subsyndromal gamblers has significant public health implications. Logistic regression analyses were used to examine a national sample of past-year recreational gamblers (N = 1,476) to identify characteristics distinguishing gamblers acknowledging gambling for excitement ("Excitement-seeking Gamblers" or EGs) and gamblers denying gambling for excitement ("Non-excitement-seeking Gamblers" or NEGs). EGs were more likely than NEGs to report alcohol use and abuse/dependence, any substance abuse/dependence, incarceration, large gambling wins and losses, more frequent and varied gambling, and symptoms of pathological gambling (i.e., at-risk gambling). Together, these findings indicate that EGs are more likely than NEGs to demonstrate problems in multiple areas characterized by impaired impulse control.

The association between pathological gambling and attempted suicide: findings from a national survey in Canada

OBJECTIVE

To examine the association between pathological gambling (PG) and attempted suicide in a nationally representative sample of Canadians.

METHODS

Data came from the Canadian Community Health Survey, Cycle 1.2, conducted in 2002, in which 36 984 subjects, aged 15 years or older, were interviewed. Logistic regression was performed with attempted suicide (in the past year) as the dependent variable. The independent variables were PG, major depression, alcohol dependence, drug dependence, and mental health care (in the past year), as well as a range of sociodemographic variables. Survey weights and bootstrap methods were used to account for the complex survey design.

RESULTS

In the final logistic regression model, which included terms for PG, major depression, alcohol dependence, and mental health care, as well as age, sex, education, and income, the odds ratio for PG and attempted suicide was 3.43 (95% confidence interval, 1.37 to 8.60).

CONCLUSIONS

PG (in the past year) and attempted suicide (in the past year) are associated in a nationally representative sample of Canadians. However, it is not possible to say from these data whether this represents a causal relation.
