Comorbid mood and adjustment disorders among pathological gamblers seeking treatment in Hong Kong

Research findings on comorbidity and pathological gambling are non–existent in Chinese communities. The objectives of this study were to: (a) determine the prevalence of comorbid mood and adjustment disorders among pathological gamblers seeking treatment in Hong Kong; (b) compare demographic profiles and clinical features in pathological gamblers with and without comorbid mood and adjustment disorders; and (c) explore the association and temporal relationship between pathological gambling and comorbid mood and adjustment disorders. Assessment instruments included demographic data, BSI, SCID-I, ASI and LIFE-RIFT. Results showed that about two-thirds (63.7%; n = 128) of 201 participants reported lifetime comorbid psychiatric disorders. Most common comorbid disorders were mood disorders (29.4%; n = 59) and adjustment disorders (20.9%; n = 42). Pathological gamblers with comorbid mood or adjustment disorders showed more severe levels of psychopathology, impairment in psychosocial functioning and gambling problems. This study is important because it is the first scientific comorbidity study among pathological gamblers in a Chinese context.     

Psychopathology in pathological gamblers seeking treatment

High rates of psychiatric symptoms have been reported in pathological gamblers. This study of psychiatric comorbidity in pathological gamblers is the first to use structured psychiatric interviews assessing DSM-III-R Axis I and II disorders. The Structured Clinical Interview for DSM III-R (SCID-P, SCID-II) was administered to 40 (25 male, 15 male) pathological gamblers seeking outpatient treatment in Minnesota for gambling, and 64 (41 male, 23 female) controls. High lifetime rates of Axis I (92%) but not Axis II (25%) psychopathology were found in pathological gamblers as compared to controls. No differences between male and female gamblers were found in rates of affective, substance use or personality disorders. Females had higher rates of anxiety disorders and histories of physical/sexual abuse. Possible associations between psychiatric disorders and pathological gambling are discussed along with gambler typologies and implications for future research.The authors wish to gratefully acknowledge the assistance of: Gary Christenson, M.D., Carol Peterson, Ph.D., William Meller, M.D., Thomas Mackenzie, M.D.     

Pharmacological treatments of pathological gambling

Medication treatment studies have demonstrated short-term efficacy of various SRIs, opioid antagonists, and mood stabilizers in sub-samples of adult treatment seeking pathological gamblers. Pathological gambling is frequently comorbid with bipolar spectrum disorders, substance abuse/dependence, and attention-deficit/hyperactivity disorder (ADHD), and comorbidity may influence treatment response in pathological gambling. This review focuses on recent research examining the treatment of pathological gambling and highlights methodological challenges for future studies.     

Pathological gambling: A review of the literature (prepared for the American Psychiatric Association task force on DSM-IV committee on disorders of impulse control not elsewhere classified)

This is a review of the literature on pathological gambling prepared for the work group on disorders of impulse control, not elsewhere classified of the American Psychiatric Association. It introduces the new DSM-IV criteria as well as outlines the phases of the career of the pathological gambler. Research discussed includes that on pathological gambling and psychiatric disorders, substance abuse, family issues, children, finances, and crime. Psychoanalytic, personality, behavioral, sociological, psychologically based addiction theories, and physiological research are also summarized. Finally, treatment outcome studies are outlined.This article is dedicated to the memory of Robert L. Custer, MD whose inspiration and encouragement stimulated much of the research discussed herein.     

Impulsivity and pathological gambling across depressive versus bipolar disorders

Impulsivity has been implicated in the development of pathological gambling (PG); sensation seeking and urgency in particular have predicted gambling pathology in undergraduate and psychiatric samples. In light of the relevance of both depressed and elevated mood to impulsivity and gambling, the components of impulsivity associated with PG across mood disorders warrants investigation. The aim of the current investigation was to examine the association between impulsivity and gambling pathology severity across depressive versus bipolar disorders. A total of 275 participants with lifetime depressive or bipolar disorder completed measures of impulsivity and gambling. Urgency was consistently associated with gambling pathology indicators; lack of perseverance was specifically associated with gambling pathology within participants with depressive disorders. Reckless action during negative mood is associated with gambling pathology across mood disorders, whereas difficulty remaining focused is associated with PG solely within depressive disorders. Impulsivity and affective comorbidity may inform current understanding of PG.     

The Role of Metacognition in Pathological Gambling: A Mediation Model

Pathological gambling involves multitudinous costs related to financial, legal, and public health care aspects, as well as to specific psychological disorders. Despite the overall evidence suggesting that comorbid disorders represent a risk factor for pathological gambling, there is scant evidence on the appropriate treatments for gamblers with such disorders. In this context, metacognitive therapy is an interesting approach because it considers psychological disorders as a result of the activation of perseverative cognitive processes and attentional strategies in response to inner events. Several studies report that metacognition is associated with different psychological problems. This study investigated the relationship among comorbid disorders, metacognition, and pathological gambling. 69 pathological gamblers at the first hospital admission and 58 controls drawn from general population (matched for age, gender, education) completed a battery of self report instruments: Symptom Checklist-90-R, Metacognition Questionnaire 30, South Oaks Gambling Scale. Compared to controls, pathological gamblers showed higher level of comorbid symptomatology and metacognition. Correlation analyses showed that: comorbid symptomatology and metacognition were positively and significantly correlated with pathological gambling; metacognition was positively and significantly associated with comorbid symptomatology. Mediation analysis indicated that dysfunctional metacognitive strategies could have an indirect effect on pathological gambling mediated by concurrent psychological disorders. These findings provide some implications for gambling treatment programs: pathological gamblers should be screened for psychiatric disorders, and metacognitive therapy could be considered a correct treatment of pathological gamblers. Metacognitive therapy might lead to the reduction of the pathological gambling by the diminishing of the concurrent psychological disorders.     

Problem Gambling and Comorbid Psychiatric and Substance Use Disorders Among Drug Users Recruited from Drug Treatment and Community Settings

Little is known about gambling rates of drug users recruited from drug treatment compared with those recruited from the community. We use the Diagnostic Interview Schedule (DIS) to provide lifetime prevalence estimates of problem gambling (i.e., at least one gambling problem) and DSM-III-R pathological gambling (i.e., at least four gambling problems) and describe the association between gambling and psychiatric disorders for drug users recruited from drug treatment settings (n = 512) and from the community (n = 478). We also report the relative risk of being a recreational and problem gambler in this sample. The sample was first interviewed in 1989–90 as a partof two NIDA-funded St. Louis-based studies. The prevalence of problem gambling in the overall sample was 22% and the prevalence of pathological gambling was 11%. There were no statistically significant differences in problem and pathological gambling rates for subjects recruited from drug treatment and those recruited from the community. The conditional prevalence rates, that is, the rate of problem and pathological gambling only among gamblers were 27% and 13.5%, respectively. Major findings indicate that problem gambling was associated with Antisocial Personality Disorder (ASPD), even after controlling for recruitment source and socio-demographic characteristics. In fact, when examining the temporal order of these disorders, we found that pathological gambling was always secondary to ASPD, occurring on average 11.4 years after the onset of ASPD. Problem gamblers, compared with everyone else, were more likely to be male, African-American, recruited from drug treatment, have ASPD and be dependent on illicit drugs. Multinomial logistic regression analysis predicted the relative risk of being a recreational and problem gambler (compared with a nongambler) in this sample according to socio-demographics, ASPD, and dependence on illicit drugs. Results imply that screening for gambling problems will need to be broad-based among drug users.     

Professional and Pathological Gamblers: Similarities and Differences

Although much recent research has focused on the gambling practices and psychosocial functioning of pathological gamblers, few investigations have examined the characteristics of professional gamblers. The current project sought to address this gap in the literature by conducting a quantitative comparison of professional and pathological gamblers. Pathological gamblers were recruited and balanced with professional gamblers on demographic variables and preferred gambling activity. A total of 22 professional gamblers and 13 pathological gamblers completed an extensive self-report battery including instruments assessing demographics, gambling behaviors and problems, other psychiatric disorders, current psychosocial functioning, recent stressful events, personality characteristics, and intelligence. Pathological and professional gamblers reported similar rates of gambling frequency and intensity and types of games played. Pathological gamblers endorsed poor psychosocial functioning, whereas professional gamblers reported a rate of psychiatric distress within a normative range. Pathological gamblers also reported lower gambling self-efficacy, greater impulsivity, and more past-year DSM-IV Axis I disorders than professional gamblers. The results of the present study shed light on the unique circumstances of professional gamblers, as well as underscore important differences between such individuals and pathological gamblers that could prove fruitful in future research and intervention and prevention efforts.     

Metacognition in Pathological Gambling and Its Relationship with Anxious and Depressive Symptomatology

Gambling disorder is associated with elevated comorbidity with depressive and anxious disorders, and one variable that might help in the understanding of this association is metacognition. In the present study, the relationship between gambling and metacognition and the mediating role of metacognition in the relationship between gambling and depressive and anxious symptomatology were assessed. The sample comprised 124 pathological gamblers from centers that assist pathological gamblers and 204 participants from the general population. The results showed that pathological gamblers had higher levels of depressive and anxious symptomatology. Additionally, pathological gamblers had higher scores for positive beliefs about worry, negative beliefs of uncontrollability and danger, and beliefs about the need to control thoughts; these factors were also positively correlated with depressive and anxious symptomatology. Metacognition also fully mediated the association between gambling and depressive and anxious symptomatology. These results suggest that metacognition could contribute to explaining gambling disorder and the symptomatology associated with it.     

Alcohol Use and Prior Substance Abuse Treatment in Relation to Gambling Problem Severity and Gambling Treatment Outcome

Recent research has made it clear that problematic gambling is often accompanied by problematic alcohol use. Unfortunately, little is known about the nature of this association, especially as it relates to gambling treatment outcome. The purpose of this study is to explore the effect of current alcohol use level and previous substance abuse treatment on the symptoms of a large cohort of pathological gamblers as well as on their response to treatment for pathological gambling. The sample included 464 men and 301 women recruited at six gambling treatment programs in Minnesota. Gambling treatment patients were assessed on a number of gambling problem severity and related clinical variables using the Gambling Treatment Outcome Monitoring System (GAMTOMS). Patients with frequent alcohol use had greater gambling involvement at baseline than infrequent alcohol users. Patients with a previous history of substance abuse treatment had more severe psychosocial problems, ostensibly resulting from their gambling behavior, than patients without past substance abuse treatment. A MANOVA with repeated measures showed that neither pretreatment alcohol use, nor past substance abuse treatment exerted significant effects on gambling treatment outcome. While the level of pretreatment alcohol use and a history of substance abuse treatment are markers for greater gambling problem severity, treatment outcome for pathological gambling was not adversely impacted by these variables.     

Risk Factors for Problematic Gambling: A Critical Literature Review

This article is a critical review of risk factors for pathological gambling categorized by demographics, physiological and biological factors, cognitive distortions, comorbidity and concurrent symptoms, and personality symptoms and characteristics. There is also a varia section (availability, parents playing, sensory characteristics, schedules of reinforcement, age of onset, and playing duration). The review found very few well established risk factors for pathological gambling (i.e. more than two studies to support the conclusions). Well established risk factors included demographic variables (age, gender), cognitive distortions (erroneous perceptions, illusion of control), sensory characteristics, schedules of reinforcement, comorbid disorders (OCD, drug abuse), and delinquency/illegal acts. An understanding of risk factors for pathological gambling should enhance prevention and treatment approaches.     

Clinical and behavioral evaluation of pathological gambling in Barcelona,Spain

This paper assesses both the clinical characteristics and gambling behavior of 45 pathological gamblers (40 male, 5 female, average age 41) in a psychiatric hospital in Barcelona, Spain. These pathological gamblers tend to have other addictions and psychiatric disorders in addition to their pathological gambling. Suicidal ideation and attempts were one of the most frequent complications with these patients. Slot and fruit machines were found to be the most preferred form of gambling. Loans and crime were frequently used by the gambler to finance his or her gambling. Nevertheless, the gambler is rarely aggessive, and legal problems resulting from serious crimes are the exception. The profile presentes is similar to that found among pathological gamblers in other countries.     

The effect of compliance-improving interventions on the cognitive-behavioural treatment of pathological gambling

This exploratory study investigated the effect of interventions designed to improve compliance and reduce dropout rates during the outpatient treatment of pathological gambling at a University-based gambling treatment clinic. Forty subjects (29 males, 11 females, mean age = 37.6) meeting DSM-IV criteria (APA, 1994) for pathological gambling were randomly assigned to either a cognitive-behavioural treatment or a cognitive-behavioural treatment combined with interventions designed to improve treatment compliance. Compliance was indicated by the completion of all treatment sessions. Outcome measures were DSM-IV criteria assessed by structured clinical interview, South Oaks Gambling Screen scores, and percentage of income gambled. Logistic regression analyses identified pretreatment characteristics predicting compliance and outcome. Compliance-improving interventions significantly reduced dropout rates, resulting in superior outcomes at posttreatment compared to the cognitive behavioural treatment alone. At 9-month follow-up, there was no difference in outcome between treatments, although both produced clinically significant change. Comorbid problem drinking, drug use, and problem gambling duration predicted poor compliance. Poor outcome was predicted by comorbid problem drinking. The clinical implications of these results are discussed in light of the exploratory nature of the study and the need for future research to address compliance, outcome, and comorbidity issues.     

Multiple Co-occurring Behaviours among Gamblers in Treatment: Implications and Assessment

A substantial portion of gamblers in treatment may have co-occurring mental health disorders including substance use disorders, especially alcohol dependency, personality disorders, affective disorders, anxiety disorders and impulse control disorders. Co-occurring mental health disorders affect treatment seeking, the treatment process and its outcome, quality of life and functioning in many mental health disorders. Participants in this study were 78 adults enrolled in state-supported out-patient services for pathological gambling and current Gamblers Anonymous attendees. The majority of participants (76.6%) had co-occurring behaviours; 55.8% had multiple co-occurring behaviours. Participants with multiple co-occurring behaviours were more likely to report that a co-occurring behaviour increased the severity of their gambling symptoms. A dose/response relationship between number of co-occurring behaviours and severity of gambling problems was found. Co-occurring behaviours can interact with gambling behaviour. Brief, validated screening instruments are available for screening and diagnosing co-occurring behaviours among gamblers presenting for treatment.     

Treatment of Female Pathological Gambling: The Efficacy of a Cognitive-Behavioural Approach

Given that a substantial proportion of current pathological gamblers are female, it is evident that women are underrepresented in the treatment outcome literature. The current study was designed to redress the limited information on the treatment of female pathological gambling. Although the use of cognitive-behavioural therapy is the most highly recommended approach as ‘best practice’ for the treatment of pathological gambling, no attempt to date has been made to evaluate the efficacy of this approach for female pathological gambling. Nineteen female pathological gamblers with electronic gaming machine problems were treated with a cognitive-behavioural program. While pathological gamblers placed on a waiting list did not show significant improvement on gambling behaviour and psychological functioning measures, the female pathological gamblers showed significant improvement on these measures over the treatment period, and maintained this improvement at the 6-month follow-up evaluation. By the completion of the follow-up period, 89% of participants no longer met diagnostic criteria for pathological gambling. Although further scientific demonstration and replication are required, the outcomes of this study indicate that the therapy that is considered ‘best practice’ in the treatment of pathological gambling is effective for female pathological gambling.     

Pathological Gambling and Posttraumatic Stress Disorder: A Study of the Co-Morbidity versus Each Alone

This report is the first empirical study to compare pathological gambling (PG), posttraumatic stress disorder (PTSD), and their co-occurrence. The sample was 106 adults recruited from the community (35 with current PG; 36 with current PTSD, and 35 with BOTH). Using a cross-sectional design, the three groups were rigorously diagnosed and compared on various measures including sociodemographics, psychopathology (e.g., dissociation, suicidality, comorbid Axis I and II disorders), functioning, cognition, life history, and severity of gambling and PTSD. Overall, the PG group reported better psychological health and higher functioning than PTSD or BOTH; and there were virtually no differences between PTSD and BOTH. This suggests that it is the impact of PTSD, rather than comorbidity per se, that appears to drive a substantial increase in symptoms. We also found high rates of additional co-occurring disorders and suicidality in PTSD and BOTH, which warrants further clinical attention. Across the total sample, many reported a family history of substance use disorder (59%) and gambling problems (34%), highlighting the intergenerational impact of these. We also found notable subthreshold PTSD and gambling symptoms even among those not diagnosed with the disorders, suggesting a need for preventive care. Dissociation measures had mixed results. Discussion includes methodology considerations and future research areas.     

Barriers in Access to the Treatment for People with Gambling Disorders. Are They Different from Those Experienced by People with Alcohol and/or Drug Dependence?

A prevalence of gambling disorders is diversified depending on the region of the world. Almost three quarters of pathological gamblers had never sought a professional treatment as well as an assistance in self-help groups. Reasons why they do not initiate a treatment are complex. The aim of the article is to compare barriers to the treatment for people with gambling disorders found in presented study and barriers to alcohol and drug treatment identified in the available literature. The semi structured interviews were applied and conducted with people with gambling disorders, social workers, therapists employed in the addiction treatment facilities, General Practitioners and psychiatrists. Selection of the respondents was based on purposive sampling. In total, 90 interviews were completed. Respondents identified individual barriers as well as structural ones. Individual barriers include internal resistance and a fear of the treatment. In turn structural barriers apply to the organization of the therapy, infrastructure, personnel, and the therapeutic program. A comparison of barriers experienced by people with gambling disorders and substance use disorders showed that they are largely similar, but people with gambling disorders also experience specific barriers. Empirical studies focused specifically on treatment needs of people experiencing gambling disorders may improve an offer of help for them. More adequate treatment options could contribute to the increasing in the number of people who start the treatment. It can result in improving their quality of life and may have positive impact on public health.     

Treatment Goal Selection for Female Pathological Gambling: A Comparison of Abstinence and Controlled Gambling

The current study was an exploratory investigation of the selection of controlled gambling as a goal of treatment for female pathological gambling. Specifically, it aimed to explore: 1) the popularity of controlled gambling as a goal of treatment; 2) the reasons pathological gamblers select abstinence and controlled gambling as goals of treatment; and 3) the characteristics of pathological gamblers attracted to abstinence and controlled gambling. The sample comprised 85 female pathological gamblers attending a cognitive-behavioural treatment program for pathological gambling. The selection of controlled gambling by one-third (34%) of the sample suggests that, at least in the Australian context, controlled gambling is a relatively popular goal of treatment for female pathological gamblers. In this study, the only differences between treatment-seeking female pathological gamblers selecting abstinence and controlled gambling were that those selecting controlled gambling were older and were less likely to endorse the belief that problematic gambling is a disease or affliction that can only be overcome by lifelong abstinence. Further research investigating the characteristics of pathological gamblers associated with controlled gambling as both a goal and outcome of treatment is required in order to ensure that treatment-seeking pathological gamblers can make an informed decision regarding their goal selection.     

Gambling Involvement and Drug Use Among Adolescents

The literature on youth gambling often notes the relationship of gambling involvement to drug use. The extent of this association and its importance toward advancing knowledge about the origins and course of adolescent gambling are discussed. The authors contend that (a) adolescent gambling, like drug use, may be a normal part of adolescence from a statistical perspective, (b) claims that the prevalence rate of problem/pathological gambling is comparable or higher than the rate of substance use disorders are not supportable at this time given the weaker methodological studies in the gambling area, (c) while research suggests that similar risk factors may be important determinants for both behavior domains, prospective studies of adolescent development are needed to further clarify which factors are unique and common to adolescent gambling, and (d) greater documentation of the harm associated with adolescent gambling is a major barrier to garnering more prevention and treatment resources for this issue.     

Pathological Gamblers: Inpatients’ versus Outpatients’ Characteristics

Several researchers and clinicians have questioned the advantages and disadvantages of inpatient and outpatient treatment for people suffering from pathological gambling. This study compares the characteristics of pathological gamblers seeking inpatient and outpatient treatment. A total of 233 pathological gamblers (inpatients = 134, outpatients = 99) participated in the study. Results show that inpatients have more severe gambling problems than those receiving outpatient services. Similar results were obtained on most other related variables such as anxiety, depression, alcohol consumption, and comorbidity. These results are discussed in terms of the costs and benefits of these two treatment modalities.
