Abstract

The purpose of this study was to verify whether tobacco use influenced treatment outcome in a population of treatment seeking individuals with gambling disorder. Gambling disorder is defined as persistent and maladaptive gambling behaviour which meets four or more outlined criteria in the DSM-5. Tobacco use is the most frequent comorbidity with gambling disorder. A total of 676 treatment seeking individuals with gambling disorder were assessed at the National Problem Gambling Clinic in London. We analysed differences in socio-demographic, clinical and gambling variables between smokers and non-smokers and the relation between smoking behaviour and treatment completion and outcome. 46.4 % (314) of our sample were daily tobacco users and were significantly younger, less likely to be in a stable relationship, more likely to be unemployed and have a lower education level. They were also significantly more likely to score higher on the AUDIT-C score and were significantly more likely to have used drugs in the last 30 days. There was no significant difference in PGSI score between smokers and non-smokers. We found that tobacco smokers did not have higher PGSI scores than non-smokers. Moreover, there was no significant difference between tobacco users and nonusers in terms of treatment completion and treatment outcome.

Background Understanding and treating the harm caused by gambling is a growing international psychiatric and public health challenge. Treatment of gambling harm may involve psychological and pharmacological intervention, in conjunction with peer support. This scoping review was conducted to identify, for the first time, the characteristics and extent of United Kingdom (UK) based gambling treatment research. We reviewed studies conducted among people seeking treatment for disordered or harmful gambling in the UK, the settings, research designs, and outcome measures used, and to identify any treatment research gaps. Methods Systematic searches of PsycInfo, PsycArticles, Scopus, PubMed, and Web of Science databases were carried out for gambling treatment research or evaluation studies conducted in the UK. Studies were included if they evaluated the effectiveness of an intervention or treatment designed to improve symptoms of harmful or problematic gambling, reported outcomes of interventions on treatment adherence, gambling symptoms, or behaviours using standardised measures, were conducted in the UK, and were published since 2000. Results Eight studies met the inclusion criteria. Four were retrospective chart reviews, two were single-participant case reports, one described a retrospective case series, and one employed a cross-sectional design. None used an experimental design. Conclusion The limited number of studies included in this review highlights a relative paucity of gambling treatment research conducted in UK settings. Further work should seek to identify potential barriers and obstacles to conducting gambling treatment research in the UK.
... Several studies also provided evidence of a link between disordered gambling and tobacco smoking (Cunningham-Williams, Cottler, Compton & Spitznagel, 1998;Potenza et al., 2004;Kessler et al., 2008;Ronzitti, Lutri, Meleck, Smith & Bowden-Jones, 2015). A Canadian survey found that 41% of heavy gamblers were current daily cigarette smokers, compared with 30% of recreational gamblers and 21% of non-gamblers (Smart & Ferris, 1996). ...

Although there is no consensus regarding the clinical status of Internet Addiction Disorder (IAD), there is a growing demand for the development and examination of various treatment protocols for Internet-related addictions. A limited body of literature examining several clinical trials allows the assumption that Cognitive Behavioural interventions, together with Motivational Interviewing strategies provide satisfying results. However, extensive evaluation programmes are necessary. There has been a growing need for a standardised methodology that would support the assessment of various treatment options to promote an evidence-based approach and recommendations over the intuition-driven one.

Objectives Tobacco smoking and gambling disorder (GD) often co-occur. However, few studies have assessed the extent to which cigarette smoking may serve to classify and/or better define GD behaviour profiles. Methods Among a large sample of n = 3,652 consecutive treatment-seeking patients with GD (91% men). Smokers were compared to non-smokers across different sociodemographic, clinical, psychopathological and personality variables. The effect sizes for the means and the proportion differences between the groups were estimated. An evaluation of the smoking changes over the last 15 years was also performed. Results From the total sample, 62.4% of gamblers reported tobacco use. A decreasing linear trend in tobacco use was observed within the studied period, women having a more irregular pattern. The use of tobacco was linked to the use of alcohol and other illegal drugs. Gamblers who smoke, as compared to those who don’t, presented lower education levels, lower social position indexes and active employment. They were younger, with an earlier age of onset, shorter duration of the gambling behavior, higher GD severity, more psychological symptoms, higher scores in novelty seeking and lower scores in reward dependence, self-directedness and self-transcendence. Conclusions Gamblers seeking treatment who smoke display particular social, clinical, psychological, temperamental and character features different from non-smoking gamblers, suggesting that the presence or absence of comorbid smoking condition in GD should always be considered when developing an optimal treatment, as gamblers who smoke might need treatment strategies different from non-smoking gamblers.

This study sought to examine the impact of tobacco use on gambling treatment. Pathological gambling (PG) is a psychiatric condition associated with significant financial, emotional, and psychosocial consequences. Elevated rates of nicotine dependence have been associated with increased gambling severity and more frequent psychiatric problems. A total of 385 treatment-seeking pathological gamblers enrolled in one of 11 gambling treatment providers in Minnesota were assessed. Linear regression modeling was used to examine demographic and clinical variables at treatment entry and the relationship between those variables and the number of days gambled at a 6-month posttreatment. Logistic regression was utilized to assess predictors of treatment completion. Daily tobacco use was reported in 244 (63.4%) subjects. Tobacco users presented with significantly more severe gambling and mental health symptoms at treatment intake. Daily tobacco use, however, was not significantly associated with the number of days gambled or with treatment completion. Although tobacco users present with greater gambling problem severity, they had similar rates of treatment completion and treatment outcomes as nonusers.

A growing body of evidence suggests that gambling frequently co-occurs with smoking, yet little is known about the degree to which nicotine and/or tobacco use influences gambling behavior. Nonetheless, an increasing number of studies suggest that acute administration of nicotine may alter other reinforcing behaviors in both animal and human models, raising the possibility that nicotine may also influence gambling behavior and craving. The purpose of this study was to examine the acute effects of nicotine on subjective and behavioral gambling responses. Twenty-eight (15 male) regular gamblers who smoke daily completed two double-blind laboratory sessions where their subjective and behavioral responses to video lottery terminal (VLT) gambling were assessed, following the administration of nicotine inhalers (NI; 4 mg deliverable) or placebo inhalers. NI significantly decreased tobacco-related cravings (p < 0.05) but did not affect gambling-related cravings, VLT betting patterns, or subjective responses (ps > 0.1). NI were found to acutely suppress tobacco-related cravings without influencing gambling. These results suggest that use of nicotine replacement therapies may be a safe option for gamblers who are attempting to quit smoking.

Gambling has become an increasingly common activity among women since the widespread growth of the gambling industry. Currently, our knowledge of the relationship between problem gambling among women and mental and physical correlates is limited. Therefore, important relationships between problem gambling and health and functioning, mental disorders, physical health conditions, and help-seeking behaviours among women were examined using a nationally representative Canadian sample. Data were from the nationally representative Canadian Community Health Survey Cycle 1.2 (CCHS 1.2; n = 10,056 women aged 15 years and older; data collected in 2002). The statistical analysis included binary logistic regression, multinomial logistic regression, and linear regression models. Past 12-month problem gambling was associated with a significantly higher probability of current lower general health, suicidal ideation and attempts, decreased psychological well-being, increased distress, depression, mania, panic attacks, social phobia, agoraphobia, alcohol dependence, any mental disorder, comorbidity of mental disorders, chronic bronchitis, fibromyalgia, migraine headaches, help-seeking from a professional, attending a self-help group, and calling a telephone help line (odds ratios ranged from 1.5 to 8.2). Problem gambling was associated with a broad range of negative health correlates among women. Problem gambling is an important public health concern. These findings can be used to inform healthy public policies on gambling.

This study was aimed at assessing the psychometric qualities of the abbreviated versions of the Alcohol Use Disorders Identification Test (AUDIT-3, AUDIT-4, AUDIT-C, AUDIT-PC, AUDIT-QF, FAST, and Five-Shot) and at comparing them to the 10-item AUDIT and the CAGE in 2 samples of Brazilian adults. The validity and internal consistency of the scales were assessed in a sample of 530 subjects attended at an emergency department and at a Psychosocial Care Center for Alcohol and Drugs. The Structured Clinical Interview for DSM-IV was used as the diagnostic comparative measure for the predictive validity assessment. The concurrent validity between the scales was analyzed by means of Pearson's correlation coefficient. The assessment of the predictive validity of the abbreviated versions showed high sensitivity (of 0.78 to 0.96) and specificity (of 0.74 to 0.94) indices, with areas under the curve as elevated as those of the AUDIT (0.89 and 0.92 to screen for abuse and 0.93 and 0.95 in the screening of dependence). The CAGE presented lower indices: 0.81 for abuse and 0.87 for dependence. The analysis of the internal consistency of the AUDIT and its versions exhibited Cronbach's alpha coefficients between 0.83 and 0.94, while the coefficient for the CAGE was 0.78. Significant correlations were found between the 10-item AUDIT and its versions, ranging from 0.91 to 0.99. Again, the results for the CAGE were satisfactory (0.77), although inferior to the other instruments. The results obtained in this study confirm the validity of the abbreviated versions of the AUDIT for the screening of alcohol use disorders and show that their psychometric properties are as satisfactory as those of the 10-item AUDIT and the CAGE.

A large, integrated survey data set provided by the Ontario Problem Gambling Centre was used to investigate psychometric properties of the Problem Gambling Severity Index (PGSI). This nine-item self-report instrument was designed to measure a single, problem gambling construct. Unlike its nearest competitor--the South Oaks Gambling Screen (SOGS)--the PGSI was designed specifically for use with a general population rather than in a clinical context. The present analyses demonstrated that the PGSI does assess a single, underlying, factor, but that this is complicated by different, multiple factor structures for respondents with differing levels of problem gambling severity. The PGSI also demonstrated small to moderate correlations with measures of gambling frequency and faulty cognitions. Overall, the PGSI presents a viable alternative to the SOGS for assessing degrees of problem gambling severity in a non-clinical context.

This study determined prevalence estimates of problem gambling and relationships to other psychiatric and substance use disorders. In 1981, the Diagnostic Interview Schedule was used to collect epidemiological information on problem gambling and other disorders from 3004 adults in St. Louis, Mo. The lifetime prevalence of pathological gambling was 0.9%; 46% of those surveyed gambled recreationally. Problem gamblers (those reporting at least one gambling-related problem) were 9.2% of the sample and were predominately White (69%), male (78.2%), and young than nongamblers. They were at increased risk for several psychiatric diagnoses, especially for antisocial personality disorder, alcoholism, and tobacco dependence. Clinicians treating alcoholism and tobacco dependence may need to screen for problem gambling. Additional research in the context of increased gambling opportunities is needed.

Evidence of an increased risk for various psychiatric disorders among pathological gamblers far exceeds our understanding of the impact that this psychiatric comorbidity has on the outcome of treatment for pathological gambling. One major source of the problem is that treatment efficacy and effectiveness studies for pathological gambling typically have not addressed comorbidity's impact on outcome. This paper discusses epidemiological, clinical, health service delivery, and research issues pertaining to the intersection of pathological gambling treatment outcome and comorbid psychiatric disorders. It is argued that this topic suffers from major knowledge gaps in terms of the nature of comorbidity of pathological gambling and other psychiatric disorders and the role of client characteristics on treatment outcome for pathological gambling. Research priorities are identified.

This meta-analysis examined outcomes of smoking cessation interventions evaluated in 19 randomized controlled trials with individuals in current addictions treatment or recovery. Smoking and substance use outcomes at posttreatment and long-term follow-up (> or = 6 months) were summarized with random effects models. Intervention effects for smoking cessation were significant at posttreatment and comparable for participants in addictions treatment and recovery; however, intervention effects for smoking cessation were nonsignificant at long-term follow-up. Smoking cessation interventions provided during addictions treatment were associated with a 25% increased likelihood of long-term abstinence from alcohol and illicit drugs. Short-term smoking cessation effects look promising, but innovative strategies are needed for long-term cessation. Contrary to previous concerns, smoking cessation interventions during addictions treatment appeared to enhance rather than compromise long-term sobriety.

Generalized anxiety disorder (GAD) is one of the most common mental disorders; however, there is no brief clinical measure for assessing GAD. The objective of this study was to develop a brief self-report scale to identify probable cases of GAD and evaluate its reliability and validity. A criterion-standard study was performed in 15 primary care clinics in the United States from November 2004 through June 2005. Of a total of 2740 adult patients completing a study questionnaire, 965 patients had a telephone interview with a mental health professional within 1 week. For criterion and construct validity, GAD self-report scale diagnoses were compared with independent diagnoses made by mental health professionals; functional status measures; disability days; and health care use. A 7-item anxiety scale (GAD-7) had good reliability, as well as criterion, construct, factorial, and procedural validity. A cut point was identified that optimized sensitivity (89%) and specificity (82%). Increasing scores on the scale were strongly associated with multiple domains of functional impairment (all 6 Medical Outcomes Study Short-Form General Health Survey scales and disability days). Although GAD and depression symptoms frequently co-occurred, factor analysis confirmed them as distinct dimensions. Moreover, GAD and depression symptoms had differing but independent effects on functional impairment and disability. There was good agreement between self-report and interviewer-administered versions of the scale. The GAD-7 is a valid and efficient tool for screening for GAD and assessing its severity in clinical practice and research.

Behavioral addictions, such as pathological gambling, kleptomania, pyromania, compulsive buying, and compulsive sexual behavior, represent significant public health concerns and are associated with high rates of psychiatric comorbidity and mortality. Although research into the biology of these behaviors is still in the early stages, recent advances in the understanding of motivation, reward, and addiction have provided insight into the possible pathophysiology of these disorders. Biochemical, functional neuroimaging, genetic studies, and treatment research have suggested a strong neurobiological link between behavioral addictions and substance use disorders. Given the substantial co-occurrence of these groups of disorders, improved understanding of their relationship has important implications not only for further understanding the neurobiology of both categories of disorders but also for improving prevention and treatment strategies.

Anxiety, although as common as depression, has received less attention and is often undetected and undertreated. To determine the current prevalence, impairment, and comorbidity of anxiety disorders in primary care and to evaluate a brief measure for detecting these disorders. Criterion-standard study performed between November 2004 and June 2005. 15 U.S. primary care clinics. 965 randomly sampled patients from consecutive clinic patients who completed a self-report questionnaire and agreed to a follow-up telephone interview. 7-item anxiety measure (Generalized Anxiety Disorder [GAD]-7 scale) in the clinic, followed by a telephone-administered, structured psychiatric interview by a mental health professional who was blinded to the GAD-7 results. Functional status (Medical Outcomes Study Short Form-20), depressive and somatic symptoms, and self-reported disability days and physician visits were also assessed. Of the 965 patients, 19.5% (95% CI, 17.0% to 22.1%) had at least 1 anxiety disorder, 8.6% (CI, 6.9% to 10.6%) had posttraumatic stress disorder, 7.6% (CI, 5.9% to 9.4%) had a generalized anxiety disorder, 6.8% (CI, 5.3% to 8.6%) had a panic disorder, and 6.2% (CI, 4.7% to 7.9%) had a social anxiety disorder. Each disorder was associated with substantial impairment that increased significantly (P < 0.001) as the number of anxiety disorders increased. Many patients (41%) with an anxiety disorder reported no current treatment. Receiver-operating characteristic curve analysis showed that both the GAD-7 scale and its 2 core items (GAD-2) performed well (area under the curve, 0.80 to 0.91) as screening tools for all 4 anxiety disorders. The study included a nonrandom sample of selected primary care practices. Anxiety disorders are prevalent, disabling, and often untreated in primary care. A 2-item screening test may enhance detection.

We investigated variables associated with quitting behaviors among current, daily, and nondaily young adult smokers in the United States. Data from the national 2003 Tobacco Use Special Cessation Supplement to the Current Population Survey were analyzed to identify factors associated with quit attempts and serious intention to quit among young adult smokers aged 18 to 30 years (n=7912). Daily smokers who smoked 20 or more cigarettes per day, had their first cigarette within 30 minutes of waking, and smoked no usual type were less likely than were their comparison groups to have 1 more or quit attempts. Nondaily smokers who were male, Hispanic, and smoked no usual type of cigarette were also less likely than were their comparison groups to report 1 or more quit attempts. Although unemployed nondaily smokers were more likely than were the employed to report intention to quit, nondaily smokers with an annual family income of $25,000 to $49,000 were less likely than were higher-income families to report intention to quit. Nicotine dependence measures were significantly associated with quitting and intention to quit among daily smokers, but sociodemographics were associated with quitting and intention to quit among nondaily smokers.

Little is known about the prevalence or correlates of DSM-IV pathological gambling (PG). Data from the US National Comorbidity Survey Replication (NCS-R), a nationally representative US household survey, were used to assess lifetime gambling symptoms and PG along with other DSM-IV disorders. Age of onset (AOO) of each lifetime disorder was assessed retrospectively. AOO reports were used to study associations between temporally primary disorders and the subsequent risk of secondary disorders. Most respondents (78.4%) reported lifetime gambling. Lifetime problem gambling (at least one Criterion A symptom of PG) (2.3%) and PG (0.6%) were much less common. PG was significantly associated with being young, male, and Non-Hispanic Black. People with PG reported first gambling significantly earlier than non-problem gamblers (mean age 16.7 v. 23.9 years, z=12.7, p<0.001), with gambling problems typically beginning during the mid-20s and persisting for an average of 9.4 years. During this time the largest annual gambling losses averaged US$4800. Onset and persistence of PG were predicted by a variety of prior DSM-IV anxiety, mood, impulse-control and substance use disorders. PG also predicted the subsequent onset of generalized anxiety disorder, post-traumatic stress disorder (PTSD) and substance dependence. Although none of the NCS-R respondents with PG ever received treatment for gambling problems, 49.0% were treated at some time for other mental disorders. DSM-IV PG is a comparatively rare, seriously impairing, and undertreated disorder whose symptoms typically start during early adulthood and is frequently secondary to other mental or substance disorders that are associated with both PG onset and persistence.

The Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) is a brief validated screen for risky drinking and alcohol abuse and dependence (alcohol misuse). However, the AUDIT-C was validated in predominantly White populations, and its performance in different racial/ethnic groups is unclear. To evaluate the validity of the AUDIT-C among primary care patients from the predominant racial/ethnic subgroups within the United States: White, African American, and Hispanic. Cross-sectional interview validation study. 1,292 outpatients from an academic family practice clinic in Texas (90% of randomly sampled eligible). Race/ethnicity was self-reported. Areas under the receiver operating curve (AuROCs) evaluated overall AUDIT-C performance in the 3 racial/ethnic groups compared to diagnostic interviews for alcohol misuse. AUDIT-C sensitivities and specificities at recommended screening thresholds were compared across racial/ethnic groups. AuROCs were greater than 0.85 in all 3 groups, with no significant differences across racial/ethnic groups in men (P = .43) or women (P = .12). At previously recommended cut points, there were statistically significant differences by race in AUDIT-C sensitivities but not specificities. In women, the sensitivity was higher in Hispanic (85%) than in African-American (67%; P = .03) or White (70%; P = .04) women. In men, the sensitivity was higher in White (95%) than in African-American men (76%; P = .01), with no significant difference from Hispanic men (85%; P = .11). The overall performance of the AUDIT-C was excellent in all 3 racial/ethnic groups as reflected by high AuROCs. At recommended cut points, there were significant differences in the AUDIT-C's sensitivity but not in specificity across the 3 racial/ethnic groups.

Challenges, Prevention, and Interventions Edited by Gerhard Meyer, University of Bremen, Germany Tobias Hayer, University of Bremen, Germany Mark Griffiths, Nottingham Trent University, United Kingdom As a leisure activity, gambling dates back to ancient times. More recently, the surge in avenues for gambling-casinos, sports betting, lotteries, and remote media (e.g.,Internet, mobile phone, interactive television) among them-finds growing numbers of people losing control over their gambling behaviour, usually at great personal and financial expense. Problem Gambling in Europe is the first book to offer a robust international knowledge base compiled by an interdisciplinary panel of researchers in gambling behaviour. Reports from 21 countries throughout Western, Eastern, Northern, and Southern Europe reveal wide variations in types of wagering activities, participation by populations, social and criminal consequences related to pathological gambling, the extent to which governments acknowledge the problem, an efforts to control it (often with the involvement of the gaming industries). For each country, noted experts discuss: Current legislation regulating gambling. Forms of gambling and their addictive potential. Participation rates and demographics. Prevalence of pathological gambling. National policies to address problem gambling. Prevention strategies and treatment methods. Problem Gambling in Europe brings insight and clarity to a widespread and complex phenomenon, and will be of considerable interest to all parties working to reduce their negative effects: social science researchers in addictions, gambling behaviour, and public health; clinical, social, and health psychologists and psychiatrists; treatment practitioners; the gaming industry; regulators; and policy makers. © Springer Science+Business Media, LLC 2009.

Objective: While considerable attention has focused on improving the detection of depression, assessment of severity is also important in guiding treatment decisions. Therefore, we examined the validity of a brief, new measure of depression severity. Measurements: The Patient Health Questionnaire (PHQ) is a self-administered version of the PRIME-MD diagnostic instrument for common mental disorders. The PHQ-9 is the depression module, which scores each of the 9 DSM-IV criteria as "0" (not at all) to "3" (nearly every day). The PHQ-9 was completed by 6,000 patients in 8 primary care clinics and 7 obstetrics-gynecology clinics. Construct validity was assessed using the 20-item Short-Form General Health Survey, self-reported sick days and clinic visits, and symptom-related difficulty. Criterion validity was assessed against an independent structured mental health professional (MHP) interview in a sample of 580 patients. Results: As PHQ-9 depression severity increased, there was a substantial decrease in functional status on all 6 SF-20 subscales. Also, symptom-related difficulty, sick days, and health care utilization increased. Using the MHP reinterview as the criterion standard, a PHQ-9 score > or =10 had a sensitivity of 88% and a specificity of 88% for major depression. PHQ-9 scores of 5, 10, 15, and 20 represented mild, moderate, moderately severe, and severe depression, respectively. Results were similar in the primary care and obstetrics-gynecology samples. Conclusion: In addition to making criteria-based diagnoses of depressive disorders, the PHQ-9 is also a reliable and valid measure of depression severity. These characteristics plus its brevity make the PHQ-9 a useful clinical and research tool.

Evidence suggests that tobacco smoking and gambling frequently co-occur. Although high rates of comorbid smoking and gambling have been documented in studies with clinical populations of pathological gamblers in treatment, in studies using samples drawn from the community, and in large-epidemiological surveys, little empirical attention has been directed towards investigating the exact nature of this relationship. In this review, we stress the literature that has examined the epidemiology, aetiology and environmental factors implicated in comorbid smoking and gambling. Publications included in the review were identified through PsycInfo, PubMed and Medline searches. Although conclusive evidence is lacking, a growing body of literature suggests that smoking and gambling might share similar neurobiological, genetic and/or common environmental influences. Comorbid tobacco smoking and gambling are highly prevalent at the event and syndrome levels. However, research investigating how smoking might affect gambling or vice versa is currently lacking. More studies that examine the impact of this comorbidity on rates of tobacco dependence and problem gambling, as well as implications for treatment outcomes, are needed.

This book examines the prevalence and consequences of problem gambling as well as approaches to treatment. In this comprehensive book, the author, Nancy M. Petry, clarifies the current understanding of gambling as a disorder, including its levels of intensity; possible origins in biological, neurological, developmental, and environmental spheres; and special issues surrounding populations that seem to be more susceptible to problem gambling, including youth, ethnic minorities, and those with comorbid affective disorders such as depression. The author reviews treatments commonly used for pathological gambling as well as nonprofessionally guided interventions such as Gamblers Anonymous. Petry then presents her own brief cognitive-behavioral approach, whose success is empirically proven in the largest known study of psychosocial treatments of problem gamblers. In this book, Petry reviews what we currently know about problem gambling and analyzes promising treatment approaches, making it an invaluable, comprehensive resource for both therapists and researchers in the field of pathological gambling.

Objective: Based on the National Epidemiological Survey of Psychiatric Disorders in South Korea conducted in 2006, we examined the prevalence, clinical correlations, comorbidities, and suicidal tendencies of pathological gamblers in the community. Method: Of the 6,510 participants who completed the Korean version of the Composite International Diagnostic Interview (K-CIDI) administered by trained lay interviewers, 5,333 subjects fully completed the Diagnostic Interview Schedule (DIS) exploring pathological gambling. The DIS has 13 items mapping to 10 criteria. Endorsement of five DSM-IV criteria was considered to reflect pathological gambling, and we considered endorsement of one to four criteria to indicate problem gambling. The frequencies of psychiatric disorders and suicidal tendency were analyzed among pathological/problem gamblers in comparison with controls; both odds ratios and significance levels were calculated. Results: The lifetime prevalence rates of pathological gambling and problem gambling were 0.8% and 3.0%, respectively. Of pathological gamblers, 79.1% had at least one psychiatric illness in comparison to the control level of 28.1%, and 62.0% of problem gamblers also had psychiatric conditions. Associations between pathological/problem gambling and alcohol use disorder, nicotine dependence, mood disorder, anxiety disorder, and suicidality were overwhelmingly positive and significant (p < 0.05), even after controlling for age and gender. Male gender, divorced/separated/widowed marital status, and urban living were all associated with increased risks of pathological and problem gambling (p < 0.05). Conclusion: Pathological/problem gambling is highly associated with substance abuse, mood and anxiety disorders, and suicidality, suggesting that clinicians should carefully evaluate and treat such psychiatric disorders in gamblers.

Pathological gambling (PG), a disabling disorder experienced by approximately 1% of adults, has few empirically validated treatments. A recent study demonstrated that 6 sessions of imaginal desensitization plus motivational interviewing (IDMI) was effective in achieving abstinence for a majority of individuals with PG. This study sought to examine whether those benefits were maintained 6 months post-treatment. Sixty-eight individuals who met DSM-IV criteria for PG were randomly assigned to 6 sessions of IDMI or Gamblers Anonymous (GA) referral over an 8-week period. Participants who failed to respond to GA were offered IDMI after the 8-week acute treatment period. All individuals who responded to IDMI were contacted after 6 months and assessed with measures of gambling severity and psychosocial functioning. Forty-four participants completed 6 sessions of IDMI (25 initially assigned to IDMI and 19 to GA). Thirty-five of the 44 (79.5%) responded during acute treatment, and all 35 were available for a 6-month evaluation. All gambling severity scales maintained statistically significant gains from baseline, although some measures showed significant worsening compared with post-IDMI treatment. Six sessions of IDMI resulted in statistically significant reductions in PG urges and behavior, which were largely maintained for 6 months.

While the majority of pathological gamblers are current cigarette smokers (CS), some have quit smoking (former smokers, FS) while others never smoked (never smokers, NS). The reasons for elevated smoking rates in pathological gambling are not known, but gamblers may use nicotine as a putative cognitive enhancer. This study evaluated impulsivity and cognitive flexibility in a sample of pathological gamblers with differing smoking status. Fifty-five subjects with pathological gambling (CS, n=34; FS, n=10; NS, n=11) underwent cognitive assessments using the Stop-Signal (SST) and Intradimensional/Extra-dimensional (ID/ED) set-shift tasks. CS reported less severe gambling problems than either FS or NS on the Yale Brown Obsessive Compulsive Scale modified for Pathological Gambling, and CS was associated with significantly fewer directional errors on the SST task, compared to NS. In addition, in CS, higher daily cigarette consumption was associated with fewer total errors on the ID/ED task. The potential role of nicotine as a cognitive enhancer was supported by objective tests of impulsivity and cognitive flexibility. Human laboratory studies using nicotine challenges in pathological gambling will shed further light on this relationship.

This paper reviews evidence pertaining to the prevalence of common comorbid disorders, including alcohol use disorder, depression, substance use disorders, nicotine dependence, anxiety disorders and antisocial personality disorder, in population-representative samples of problem and pathological gamblers. A systematic search was conducted for peer-reviewed and unpublished articles reported between 1 January 1998 and 20 September 2010. Only studies which examined the prevalence of comorbid conditions in problem and/or pathological gamblers from a general population sample using randomized sampling methods and standardized measurement tools were included. Meta-analysis techniques were then performed to synthesize the included studies and estimate the weighted mean effect size and heterogeneity across studies. Eleven eligible studies were identified from the literature. Results from across the studies indicated that problem and pathological gamblers had high rates of other comorbid disorders. The highest mean prevalence was for nicotine dependence (60.1%), followed by a substance use disorder (57.5%), any type of mood disorder (37.9%) and any type of anxiety disorder (37.4%). However, there was evidence of moderate heterogeneity across studies, suggesting that rate estimates do not necessarily converge around a single population figure, and that weighted means should be interpreted with caution. Problem and pathological gamblers experience high levels of other comorbid mental health disorders and screening for comorbid disorders upon entering treatment for gambling problems is recommended. Further research is required to explore the underlying causes of variability observed in the prevalence estimates.

Depression, anxiety and somatization are the most common mental disorders in primary care as well as medical specialty populations; each is present in at least 5-10% of patients and frequently comorbid with one another. An efficient means for measuring and monitoring all three conditions would be desirable. Evidence regarding the psychometric and pragmatic characteristics of the Patient Health Questionnaire (PHQ)-9 depression, generalized anxiety disorder (GAD)-7 anxiety and PHQ-15 somatic symptom scales are synthesized from two sources: (1) four multisite cross-sectional studies (three conducted in primary care and one in obstetric-gynecology practices) comprising 9740 patients, and (2) key studies from the literature that have studied these scales. The PHQ-9 and its abbreviated eight-item (PHQ-8) and two-item (PHQ-2) versions have good sensitivity and specificity for detecting depressive disorders. Likewise, the GAD-7 and its abbreviated two-item (GAD-2) version have good operating characteristics for detecting generalized anxiety, panic, social anxiety and post-traumatic stress disorder. The optimal cutpoint is > or = 10 on the parent scales (PHQ-9 and GAD-7) and > or = 3 on the ultra-brief versions (PHQ-2 and GAD-2). The PHQ-15 is equal or superior to other brief measures for assessing somatic symptoms and screening for somatoform disorders. Cutpoints of 5, 10 and 15 represent mild, moderate and severe symptom levels on all three scales. Sensitivity to change is well-established for the PHQ-9 and emerging albeit not yet definitive for the GAD-7 and PHQ-15. The PHQ-9, GAD-7 and PHQ-15 are brief well-validated measures for detecting and monitoring depression, anxiety and somatization.

Sixty-eight individuals were randomised to either six sessions of imaginal desensitisation plus motivational interviewing (IDMI) or Gamblers Anonymous. Individuals assigned to IDMI had significantly greater reductions in Yale-Brown Obsessive Compulsive Scale Modified for Pathological Gambling total scores, gambling urges and gambling behaviour. People who failed to respond to Gamblers Anonymous reported significantly greater reduction in pathological gambling symptoms following later assignment to IDMI. Abstinence was achieved by 63.6% during the acute IDMI treatment period.

Tobacco smoking and pathological gambling (PG) frequently co-occur. Little is known, however, about the clinical correlates and co-occurring psychiatric disorders in treatment-seeking pathological gamblers with and without daily tobacco smoking. Among a sample of 465 consecutive treatment-seeking subjects with current DSM-IV PG, those with daily tobacco smoking were compared to those without daily tobacco smoking on measures of gambling symptom severity (South Oaks Gambling Screen [SOGS] and the Yale Brown Obsessive Compulsive Scale Modified for Pathological Gambling [PG-YBOCS]), types of gambling, social and legal problems, and co-occurring disorders. Two hundred and nine (44.9%) of the 465 subjects with PG reported current daily tobacco smoking. Gamblers with daily tobacco smoking as compared to those without had higher SOGS scores, had more severe PG-YBOCS behavior scores, endorsed more DSM-IV PG criteria, lost more money gambling, and were more likely to engage in non-strategic gambling, and were less likely to have a co-occurring mood disorder. Gamblers with daily tobacco smoking and a current substance use disorder reported a greater percentage of income lost to gambling during the past year. Daily tobacco smoking in PG is common and associated with multiple important clinical features including more severe gambling and financial problems. These findings suggest that pathological gamblers with daily tobacco smoking might need unique or enhanced treatment strategies.

The Gambling Task (GT) has demonstrated sensitivity to a type of decision-making that differentiates individuals manifesting substance use disorders from those without such disorders. However, studies have not yet compared the GT performance of "heavy smokers" to the performance of never-smokers. In the present study, the GT performance of "heavy smokers" (n = 39) and never-smokers (n = 32) recruited from the community was compared in an experimental design. Analysis of covariance showed that "heavy smokers" performance on the GT was significantly worse than that of never-smokers (p < .01). Implications, the study's limitations and future directions are discussed.

Nicotine dependence frequently co-occurs with subsyndromal and pathological levels of gambling. The relationship of nicotine dependence, levels of gambling pathology, and other psychiatric disorders, however, is incompletely understood. To use nationally representative data from the National Epidemiologic Survey on Alcohol and Related Conditions to examine the influence of DSM-IV nicotine dependence on the association between pathological gambling severities and other psychiatric disorders. Face-to-face interviews were conducted with 43,093 adults living in households and group-quarters in the United States. The main outcome measure was the co-occurrence of current nicotine dependence and Axis I and II disorders and severity of gambling based on the 10 inclusionary diagnostic criteria for pathological gambling. The study was conducted from 2001 to 2002. Among non-nicotine-dependent respondents, increasing gambling severity was associated with greater psychopathology for the majority of Axis I and II disorders. This pattern was not uniformly observed among nicotine-dependent subjects. Significant nicotine-by-gambling-group interactions were observed for multiple Axis I and II disorders. All significant interactions involved stronger associations between gambling and psychopathology in the non-nicotine-dependent group. In a large national sample, nicotine dependence influences the associations between gambling and multiple psychiatric disorders. Subsyndromal levels of gambling are associated with significant psychopathology. Nicotine dependence accounts for some of the elevated risks for psychopathology associated with subsyndromal and problem/pathological levels of gambling. Additional research is needed to examine specific prevention and treatment for individuals with problem/pathological gambling with and without nicotine dependence.

To demonstrate the link between gambling, alcohol and drug problems among Ontario adults and to present information on the relationship between expenditures on gambling and type of gambling with gambling problems. Using data collected in a 1994 telephone survey of 2,016 randomly chosen Ontario adults, gambling problems are related to the CAGE scale of alcohol problems and the ICD-10 measure of alcohol dependence, as well as smoking, other drug use, and demographic variables. Descriptive tables based on crosstabulations and means are provided, as well as a series of 9 logistic regression models. The most significant predictor of gambling problems was the amount spent on gambling in the preceding 30 days, with alcohol dependence on the ICD-10 scale and age also important predictors. Lottery players, compared to other gamblers, are more likely to be male, relatively less affluent, older on average, more likely to report alcohol problems (but not dependence) and be currently smoking. The results make clear that heavy drinking and drinking problems are associated with higher levels of spending on gambling and reports of gambling problems. This leads to the suggestion that treatment programs for those with gambling, alcohol or other drug problems should assess that possibility of comorbidity, since the presence of more than one of these problems can significantly affect the success of treatment and contribute to relapse.
Article
To critically review the current literature on pathological gambling as regards the significant psychiatric comorbidities associated with it. The authors synthesized information found via electronic searches (MEDLINE) and bibliographic-directed searches in over 60 publications. Pathological gamblers frequently have comorbid substance use disorders. In addition, a subset appear to have comorbid antisocial personality disorder, but they represent a minority when compared with those people who have acquired their antisocial traits as a consequence of their gambling behaviour. A comorbidity with the mood disorders is probable, but methodological concerns and inconsistencies with the data prevent further delineation of this. Emerging research for other disorders possibly associated with pathological gambling is also reviewed. Pathological gambling is associated with significant psychiatric comorbidity. Recommendations for future research are described.

To evaluate the 3 alcohol consumption questions from the Alcohol Use Disorders Identification Test (AUDIT-C) as a brief screening test for heavy drinking and/or active alcohol abuse or dependence. Patients from 3 Veterans Affairs general medical clinics were mailed questionnaires. A random, weighted sample of Health History Questionnaire respondents, who had 5 or more drinks over the past year, were eligible for telephone interviews (N = 447). Heavy drinkers were oversampled 2:1. Patients were excluded if they could not be contacted by telephone, were too ill for interviews, or were female (n = 54). Areas under receiver operating characteristic curves (AUROCs) were used to compare mailed alcohol screening questionnaires (AUDIT-C and full AUDIT) with 3 comparison standards based on telephone interviews: (1) past year heavy drinking (>14 drinks/week or > or =5 drinks/ occasion); (2) active alcohol abuse or dependence according to the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition, criteria; and (3) either. Of 393 eligible patients, 243 (62%) completed AUDIT-C and interviews. For detecting heavy drinking, AUDIT-C had a higher AUROC than the full AUDIT (0.891 vs 0.881; P = .03). Although the full AUDIT performed better than AUDIT-C for detecting active alcohol abuse or dependence (0.811 vs 0.786; P<.001), the 2 questionnaires performed similarly for detecting heavy drinking and/or active abuse or dependence (0.880 vs 0.881). Three questions about alcohol consumption (AUDIT-C) appear to be a practical, valid primary care screening test for heavy drinking and/or active alcohol abuse or dependence.

To assess the effects of a smoking cessation program for recovering alcoholics on use of alcohol, tobacco and illicit drugs after discharge from residential treatment. A randomized community intervention trial design was employed in which 12 residential drug treatment centers in Iowa, Kansas and Nebraska were matched and then randomly assigned to the intervention or control condition. Approximately 50 adult residents (inpatients) from each site were followed for 12 months after treatment discharge. Participating residents in the six intervention centers received a 4-part, individually tailored, smoking cessation program while those in the six control sites received usual care. Both moderate and heavy drinking rates were reduced in the intervention group. Intervention site participants were significantly more likely than controls to report alcohol abstinence at both the 6-month (OR = 1.59, 95%CI: 1.09-2.35) and 12-month assessment (OR = 1.84, 95%CI: 1.28-2.92). Illicit drug use rates were comparable. Effect of the intervention on tobacco quit rates was not statistically significant. Counseling alcoholics in treatment to quit smoking does not jeopardize the alcohol recovery process. However, low-intensity tobacco interventions are unlikely to yield high tobacco quit rates.

This study developed prevalence estimates of gambling-related disorders in the United States and Canada, identified differences in prevalence among population segments, and identified changes in prevalence over the past 20 years. A meta-analytic strategy was employed to synthesize estimates from 119 prevalence studies. This method produced more reliable prevalence rates than were available from any single study. Prevalence estimates among samples of adolescents were significantly higher than estimates among samples of adults for both clinical (level 3) and subclinical (level 2) measures of disordered gambling within both lifetime and past-year time frames (e.g., 3.9% vs 1.6% for lifetime estimates of level 3 gambling). Among adults, prevalence estimates of disordered gambling have increased significantly during the past 20 years. Membership in youth, treatment, or prison population segments is significantly associated with experiencing gambling-related disorders. Understanding subclinical gamblers provides a meaningful opportunity to lower the public health burden associated with gambling disorders. Further research is necessary to determine whether the prevalence of disordered gambling will continue to increase among the general adult population and how prevalence among adolescents will change as this cohort ages.

Cigarette smoking and gambling often co-occur, but very little is known about smoking or its correlates in disordered gamblers. This study compared gambling and psychosocial problems in treatment-seeking gamblers who smoke versus those who do not. At intake to gambling treatment programs, gamblers completed the addiction severity index (ASI) and gambling questionnaires. Subjects were categorized into non-daily smokers (n=107) and daily smokers (n=210). Differences in demographics, gambling variables and ASI composite scores were compared between the groups. The daily smokers were more likely to have a history of treatment for a substance use disorder than the non-daily smokers. After controlling for substance abuse treatment histories, gender and age, the daily smokers demonstrated more severe gambling, family/social and psychiatric problems. Compared to non-daily smokers, the daily smokers gambled on more days and spent more money gambling; they also 'craved' gambling more and had lower perceived control over their gambling. The daily smokers were more likely to be taking psychiatric medications, and they experienced psychiatric symptoms, especially anxiety symptoms, on a greater number of days than non-daily smokers. Results from this study suggest that about two-thirds of treatment-seeking gamblers are current daily cigarette smokers, and smoking status is associated with more severe gambling and psychiatric symptoms. These results warrant further investigation of smoking in gamblers and whether smoking adversely affects the course of treatment or outcomes among gamblers.
Article
Accumulating evidence suggests that treatment-seeking problem gamblers have high rates of substance abuse. However, relatively little is known about the relation between gambling problems and specific psychoactive substances apart from alcohol and methadone-treated opiate addicts. In this study of 169 individuals seeking outpatient treatment for problem gambling, lifetime drug use and medication use were very high. Approximately half of the sample were using a psychiatric medication at the time they sought gambling treatment while very few individuals were using other drugs. Gambling treatment outcomes were unrelated to history of drug or medication use. No evidence was found for substitution of psychoactive substance use for gambling during the follow-up year. These findings indicate that gamblers are more likely to be involved with drug and medication use compared to the general population, but that such histories are not associated with gambling treatment outcomes.
Article
Few studies have examined the smoking behaviors of problem gamblers. A high proportion of problem gamblers calling a gambling helpline reported daily tobacco smoking (43.1%). Problem gamblers reporting daily tobacco smoking more frequently acknowledged depression and suicidality secondary to gambling, gambling-related arrests, alcohol and drug use problems, mental health treatment, and problems with casino slot machine gambling. The findings substantiate the relationship in problem gamblers between tobacco smoking and psychiatric symptomatology, particularly other substance use problems. The high proportion of callers reporting daily tobacco smoking highlights the need for enhanced smoking cessation efforts in problem gamblers.

To present nationally representative data on lifetime prevalence and comorbidity of pathological gambling with other psychiatric disorders and to evaluate sex differences in the strength of the comorbid associations. Data were derived from a large national sample of the United States. Some 43,093 household and group quarters residents age 18 years and older participated in the 2001-2002 survey. Prevalence and associations of lifetime pathological gambling and other lifetime psychiatric disorders are presented. The diagnostic interview was the National Institute on Alcohol Abuse and Alcoholism Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version. Fifteen symptom items operationalized the 10 pathological gambling criteria. The lifetime prevalence rate of pathological gambling was 0.42%. Almost three quarters (73.2%) of pathological gamblers had an alcohol use disorder, 38.1% had a drug use disorder, 60.4% had nicotine dependence, 49.6% had a mood disorder, 41.3% had an anxiety disorder, and 60.8% had a personality disorder. A large majority of the associations between pathological gambling and substance use, mood, anxiety, and personality disorders were overwhelmingly positive and significant (p < .05), even after controlling for sociodemographic and socioeconomic characteristics. Male sex, black race, divorced/separated/widowed marital status, middle age, and living in the West and Midwest were associated with increased risk for pathological gambling. Further, associations between alcohol dependence, any drug use disorder, drug abuse, nicotine dependence, major depressive episode, and generalized anxiety disorder and pathological gambling were stronger among women than men (p > .05). Pathological gambling is highly comorbid with substance use, mood, anxiety, and personality disorders, suggesting that treatment for one condition should involve assessment and possible concomitant treatment for comorbid conditions.
Article
Evidence supports phenomenological, clinical, epidemiological and biological links between problem/pathological gambling and tobacco use. An improved understanding of the relationship would be helpful in treating individuals with co-occurring pathological gambling and nicotine dependence. This study investigates the tobacco use behaviors of 225 adults (mean age +/- SD = 47.3 +/- 11.0 years; number of women = 120 [53.3%]) who were recruited for pharmacological treatment of pathological gambling. All subjects met criteria for pathological gambling based upon the Structured Clinical Interview for Pathological Gambling (SCI-PG), a DSM-IV-based diagnostic interview, and were assessed at baseline with multiple reliable and valid measures of gambling severity. 159 (70.7%) subjects were either current (n = 110; 48.9%) or prior daily smokers (n = 49; 21.8%). Compared with the group of never smokers, the group of current and prior daily smokers was more likely to be older (F = 3.55; df = 2, 222; p = 0.030), be female (chi square = 10.85; df = 2; p = 0.004), and have stronger urges to gamble (F = 128.15; df = 2,222; p < 0.001). Daily tobacco use in treatment-seeking pathological gamblers is common and associated with more severe urges to gamble. Treatments targeting urges in individuals with pathological gambling and current or prior daily tobacco use should be examined.

Pathologic gambling is believed to be associated with adverse health consequences, but no prior studies have rigorously evaluated these relationships. We sought to examine medical disorders and health service utilization associated with problem and pathologic gambling. A total of 43,093 adults aged 18 years and older were evaluated in the 2001 to 2002 National Epidemiologic Survey on Alcohol and Related Conditions. Self-reported medical diagnoses and past-year medical services used were assessed. Pathologic gamblers were more likely than low-risk individuals to have been diagnosed with tachycardia (odds ratio [OR] = 1.77; 95% confidence interval [CI] = 1.05-2.97), angina (OR = 2.35; 95% CI = 1.33-4.15), cirrhosis (OR = 3.90; 95% CI = 1.11-13.72), and other liver disease (OR = 2.98; 95% CI = 1.07-8.26). Gambling severity was also associated with higher rates of medical utilization with pathologic gamblers more likely than low-risk individuals to have been treated in the emergency room in the year before the survey (OR = 1.98; 95% CI = 1.27-3.09). Significant effects of gambling severity remained even after controlling for demographic characteristics (age, gender, ethnicity, marital status, education, income, and region of the country) and behavioral risk factors such as body mass index, alcohol abuse and dependence, nicotine dependence, and mood and anxiety disorders. A lifetime diagnosis of pathologic gambling is associated with several medical disorders and increased medical utilization, perhaps leading to a burden on healthcare costs in the United States.
