Prevalence of comorbid disorders in problem and pathological gambling: systematic review and meta‐analysis of population surveys

AIMS 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. METHODS A systematic search was conducted for peer-reviewed and unpublished articles reported between 1 January 1998 and 20 September 2010.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. RESULTS 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. CONCLUSIONS 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.

Sex differences in the treatment needs and outcomes of problem gamblers

Previous studies have found significant differences between men and women who have sought help for problems associated with their gambling. While this raises the possibility of differing treatment needs, much of the research into treating problem gamblers is based on all-male samples. This article seeks to remedy this situation by reporting on sex differences in the treatment of 1,520 problem gamblers, almost half of whom are female, who sought help in the state of Victoria, Australia, between July 1996 and June 1997. In contrast to the primarily external concerns such as employment and legal matters reported by males, females attending for problem gambling counseling were more likely to report problems with their physical and intrapersonal functioning and were more likely to report resolution of their problems. Male clients were more likely to have their cases closed and be referred to other agencies for assistance.

Adolescent Gambling Behaviour and Attitudes: A Prevalence Study and Correlates in an Australian Population

There is considerable evidence that a range of risk factors are associated with adolescent problem gambling. Using a representative sample of 2,788 eighth grade students in Victoria, Australia, the primary aim of this study was to examine the degree to which these risk factors are associated with different levels of adolescent gambling participation, rather than gambling at problematic levels. This study also aimed to obtain prevalence estimates of adolescent gambling and examine the gambling attitudes of adolescents. It was found that there were significant associations between different levels of gambling involvement and a range of risk factors. However, when all predictor variables were considered simultaneously in the prediction of higher involvement in gambling activities, only male gender, drinking alcohol, using marijuana, and few perceived rewards at school were statistically significant predictors. For males, the most important predictors for greater gambling involvement were other antisocial and risk-taking behaviours. In contrast, dissatisfaction with peers and school connectedness was important in predicting greater gambling involvement for females. The study shows the usefulness of a risk and protective factor approach to understanding gambling participation in an adolescent population and that there is much to be gained from understanding the nuances of gendered gambling behaviour in the context of studying gambling participation and attitudes rather than simply in the context of studying disordered or problematic gambling.

Using the CPGI to Determine Problem Gambling Prevalence in Australia: Measurement Issues

Most states and territories in Australia have adopted the Problem Gambling Severity Index (PGSI) of the Canadian Problem Gambling Index as the standard measure of problem gambling in their prevalence studies and research programs. However, notwithstanding this attempted standardisation, differences in sampling and recruitment methodologies and in some cases the modification of the scoring methods used in the PGSI have lead to substantial difficulties in comparison of the prevalence rates obtained in different studies. This paper focuses on how these two actions may significantly underestimate the true prevalence percent of problem gambling in Australian studies of the prevalence of problem gambling. It is recommended that the original and validated version of the PGSI is used in future Australian prevalence studies and that prevalence in community studies is studied across the whole community not arbitrarily restricted sub-samples. The adoption of valid scoring methods and unbiased sampling procedures will lead to more accurate and comparable prevalence studies.

Prevalence and determinants of gambling disorder among older adults: a systematic review.

AIMS This paper aims to systematically review studies on the prevalence of gambling disorder among older adults aged 60years and above and to summarize the evidence on the determinants, risk factors as well as the comorbidities associated with it. METHODS A systematic search was conducted for peer-reviewed, journal articles between 1st January 1995 and 1st May 2013. Only original studies which were published in English, included participants older than 60years of age and provided prevalence figures specifically among them, and where participants were assessed to have a gambling disorder by a validated instrument in non-treatment seeking/non-clinical setting were included. RESULTS 25 eligible studies were identified from the literature. The prevalence of lifetime gambling disorder ranged from 0.01% to 10.6% across studies. Prevalence of gambling disorder is higher among the younger age groups (of older adults) and among males as compared to females. Those with gambling disorder were more likely to be single or divorced/separated. Findings indicate that older adults may gamble more in an effort to ameliorate negative emotional states; they may have limited access to other exciting activities or they may be unable to participate in activities that they were previously able to and they might attempt to fill this gap with gambling. CONCLUSIONS Gambling disorder among older adults is a significant problem. Fixed incomes and limited prospects of future earnings make them an extremely vulnerable group. There is an urgent need to understand the phenomenon of gambling disorder in older adults.

Problem Gambling and Intimate Partner Violence: A Systematic Review and Meta-Analysis

This study provides a systematic review of the empirical evidence related to the association between problem gambling and intimate partner violence (IPV). We identified 14 available studies in the systematic search (8 for victimisation only, 4 for perpetration only and 2 for both victimisation and perpetration). Although there were some equivocal findings, we found that most of the available research suggests that there is a significant relationship between problem gambling and being a victim of IPV. There was more consistent evidence that there is a significant relationship between problem gambling and perpetration of IPV. Meta-analyses revealed that over one third of problem gamblers report being victims of physical IPV (38.1%) or perpetrators of physical IPV (36.5%) and that the prevalence of problem gambling in IPV perpetrators is 11.3%. Although the exact nature of the relationships between problem gambling and IPV is yet to be determined, the findings suggest that less than full employment and clinical anger problems are implicated in the relationship between problem gambling and IPV victimization and that younger age, less than full employment, clinical anger problems, impulsivity, and alcohol and substance use are implicated in the relationship between problem gambling and IPV perpetration. The findings highlight the need for treatment services to undertake routine screening and assessment of problem gambling, IPV, alcohol and substance use problems, and mental health issues and provide interventions designed to manage this cluster of comorbid conditions. Further research is also required to investigate the relationship between problem gambling and violence that extends into the family beyond intimate partners.

Problem gambling and family violence: Prevalence and patterns in treatment-seekers

The primary aim of this study was to explore the prevalence and patterns of family violence in treatment-seeking problem gamblers. Secondary aims were to identify the prevalence of problem gambling in a family violence victimisation treatment sample and to explore the relationship between problem gambling and family violence in other treatment-seeking samples. Clients from 15 Australian treatment services were systematically screened for problem gambling using the Brief Bio-Social Gambling Screen and for family violence using single victimisation and perpetration items adapted from the Hurt-Insulted-Threatened-Screamed (HITS): gambling services (n=463), family violence services (n=95), alcohol and drug services (n=47), mental health services (n=51), and financial counselling services (n=48). The prevalence of family violence in the gambling sample was 33.9% (11.0% victimisation only, 6.9% perpetration only, and 16.0% both victimisation and perpetration). Female gamblers were significantly more likely to report victimisation only (16.5% cf. 7.8%) and both victimisation and perpetration (21.2% cf. 13.0%) than male gamblers. There were no other demographic differences in family violence prevalence estimates. Gamblers most commonly endorsed their parents as both the perpetrators and victims of family violence, followed by current and former partners. The prevalence of problem gambling in the family violence sample was 2.2%. The alcohol and drug (84.0%) and mental health (61.6%) samples reported significantly higher rates of any family violence than the gambling sample, while the financial counselling sample (10.6%) reported significantly higher rates of problem gambling than the family violence sample. The findings of this study support substantial comorbidity between problem gambling and family violence, although this may be accounted for by a high comorbidity with alcohol and drug use problems and other psychiatric disorders. They highlight the need for routine screening, assessment and management of problem gambling and family violence in a range of services.

Health, Lifestyle, and Gender Influences on Aging Well: An Australian Longitudinal Analysis to Guide Health Promotion

A primary societal goal for aging is enabling older people to continue to live well as long as possible. The evidence base around aging well (“healthy,” “active,” and “successful” aging) has been constructed mainly from academic and professional conceptualizations of mortality, morbidity, functioning, and psychological well-being with some attention to lay views. Our study aims to inform action on health promotion to achieve aging well as conceptualized by qualitative research identifying what older Australians themselves value most: continuing to live as long as possible in the community with independence in daily living, and good self-rated health and psychological well-being. Multivariate survival analyses from the Melbourne longitudinal studies on healthy aging program found that important threats to aging well for the total sample over a 12-year period were chronological age, multi-morbidity, low perceived social support, low nutritional score, and being under-weight. For men, threats to aging well were low strain, perceived inadequacy of social activity, and being a current smoker. For women, urinary incontinence, low physical activity and being under-weight were threats to aging well. The findings indicate that healthy lifestyles can assist aging well, and suggest the value of taking gender into account in health promotion strategies.

Predictors of critical care admission in emergency department patients triaged as low to moderate urgency

AIM This paper is a report of a study to identify predictors of critical care admission in emergency department patients triaged as low to moderate urgency that may be apparent early in the emergency department episode of care. Background. Observations of clinical practice show that a number of emergency department patients triaged as low to moderate urgency require critical care admission, raising questions about the relationship between illness severity and physiological status early in the emergency department episode of care. METHODS A retrospective case control design was used. All participants were aged over 18 years, triaged to Australasian Triage Scale categories 3, 4 or 5, and attended emergency department between 1 July 2004 and 30 June 2005. Cases were admitted to intensive care unit or coronary care unit and controls were admitted to general medical or surgical units. Cases (n = 193) and controls (n = 193) were matched by age, gender, emergency department discharge diagnosis and triage category. RESULTS Critical care admission associated with: (i) a presenting complaint of nausea, vomiting and diarrhoea (OR = 3.40, 95%CI:1.22-9.47, P = 0.019), (ii) heart rate abnormalities at triage (OR = 2.10, 95%CI:1.19-3.71, P = 0.011), (iii) temperature abnormalities at triage (OR = 2.87 95%CI:1.05-7.89, P = 0.041), (iv) respiratory rate at first nursing assessment (OR = 1.66, 95%CI:1.05-2.06, P = 0.31) or (v) heart rate abnormalities at first nursing assessment (OR = 1.57, 95%CI = 1.04-2.39, P = 0.033). CONCLUSION Derangements in temperature, respiratory rate and heart appear to increase risk of critical care admission. Further work using a prospective approach is needed to establish which physiological parameters have the highest predictive validity, the level(s) of physiological abnormality with highest clinical utility, and the optimal timing for collection of physiological data.
