Do bettors prefer long shots because they are risk-lovers,or are they just overconfident?

This study examines whether bettors' risk preferences or overconfidence in choosing winners better explains their well documented preference for low-probability wagers. Although previous studies using racetrack data often suggest that risk-loving behavior explains long-shot preference, such data cannot distinguish between the alternative explanations. We use football betting data to make the comparison and find that overconfidence more closely fits the data. This result complements evidence of overconfidence from behavioral studies as well as stock-market models of overconfident noise traders.

Is an e-mental health programme a viable way to reach affected others of disordered gamblers? A feasibility study focusing on access and retention

Although affected family members (AFMs) of disordered gamblers suffer from highly stressful living conditions and are in need of specialized help, access to and knowledge of professional support is limited. To improve this situation, an e-mental health programme called EfA with one information module and five consecutive training modules was developed. The study investigated (1) promotion of and referral to EfA, (2) duration of visits and conversion rate, and (3) participants’ characteristics and retention in EfA. In 9 months, 6357 visits were counted. Most visitors arrived at the website via direct access. Those using search terms most commonly used phrases that were used in promotional materials. Per month, 16.1 new potential participants registered. The final sample consisted of 126 participants, most of them female, with high daily Internet usage and low use of prior professional support or self-help. More than one-third finished all modules. This is the first time that data on an e-mental health programme for this clientele was collected in Germany. Findings imply the importance of promoting such a programme in order to reach a clientele that has not had prior help and also show that it is a viable way to reach AFMs.     

AN EXPLORATION OF THE THERAPEUTIC RELATIONSHIP AND COUNSELLING OUTCOMES IN A PROBLEM GAMBLING COUNSELLING SERVICE

This study examined the relationship between a number of counselling process variables thought to influence counselling outcomes in a sample of 150 clients undertaking short‐term counselling in the state‐wide government funded Gambler's Help problem gambling counselling services in Victoria, Australia. Factors measured included psychosocial well‐being of clients prior to and after counselling, client readiness to change, self‐reported gambling activity levels before and after counselling, self‐assessment of current gambling behaviour, strength of therapeutic alliance, self‐reported counselling outcomes achieved in the area of symptoms, life matters, and related problems and a measure of client satisfaction with the service. The therapeutic alliance was found to have the strongest predictive power with respect to the level of problem resolution achieved by clients across all but one of the problem areas. The implications of these findings for clinical social work practice and education of practitioners are noted.     

A scoping review of co-morbidity in individuals with disordered gambling

Individuals with disordered gambling often report at least one other lifetime psychiatric diagnosis. Although prevalence rates vary, there is substantial evidence for co-morbidity being the rule rather than the exception. Despite this known association, there has not been a recent comprehensive review of co-morbidity in disordered gambling other than prevalence surveys. The goal of this study was to broadly summarize and review the current literature on the extent, range and nature of disordered gambling co-morbidity. Following an initial search and screening of 6 databases, 251 articles were included in the final synthesis and evaluation. The main findings showed that few studies examine the mechanisms of co-morbidity in gambling beyond prevalence rates; few studies report on temporal sequencing of gambling and co-morbid disorders; there is a lack of treatment evaluation studies designed specifically for dual-diagnosis individuals; there is a need for system-level initiatives to address co-morbidity at the policy level; and the substance use literature may act as a useful model for guiding future gambling research on co-morbidity. The results suggest that despite a reasonable amount of published research on co-morbidity in disordered gambling, most study conclusions relegate to acknowledgements of high co-occurrence between disorders without follow-up.     

Divergent Validity of Measures of Cognitive Distortions, Impulsivity, and Time Perspective in Pathological Gambling

The present study assessed the divergent validity of several self-report and objective behavioral measures for assessing pathological gambling using three samples divided by South Oaks Gambling Scale score [Lesieur, & Blume (1987). American Journal of Psychiatry, 144, 1184–1188]: pathological gamblers, potential pathological gamblers, and non-pathological gamblers. Self-report measures included the Gamblers’ Beliefs Questionnaire [GBQ; Steenbergh, Meyers, May, & Whelan (2002). Psychology of Addictive Behaviors, 16, 143–149], the Gambling Passion Scale [GPS; Rousseau, Vallerand, Ratelle, Mageau, & Provencher, (2002). Journal of Gambling Studies, 18, 45–66], the Eysenck Impulsivity Questionnaire [EIQ; Eysenck, & Eysenck (1978). Psychological Reports, 43, 1247–1255], and the Stanford Time Perspective Inventory [STPI; Zimbardo, & Boyd (1999). Journal of Personality and Social Psychology, 77, 1271–1288]. Behavioral tasks included the delay discounting task [Madden, Petry, Badger, & Bickel (1997). Experimental & Clinical Psychopharmacology, 5, 256–263] and the Future Time Perspectives [FTP; Wallace (1956). Journal of Abnormal Psychology, 52, 240–245]. The GBQ, GPS, Impulsivity subscale of the EIQ, and DDT all exhibited robust divergent validity, however, neither measure of time perspective discriminated between groups. Applications of these findings to etiological research and clinical contexts are discussed.This work was originally presented in November, 2003 at the 37th annual convention of the Association for the Advancement of Behavior Therapy in Boston, MA.     

Prevalence Estimates of Gambling Participation and Problem Gambling among 16–18-year-old Students in Iceland: A Comparison of the SOGS-RA and DSM-IV-MR-J

The aim of this study was to estimate gambling participation and problem gambling among Icelandic adolescents. Participants were 750 16–18-year-old students, 371 girls and 379 boys. The rate of problem gambling was estimated with the SOGS-RA and DSM-IV-MR-J. Results indicated that 96% of adolescents had gambled in their lifetime, 79% at least once in the preceding year and about 10% gamble at least once a week. A psychometric evaluation of the two screening scales revealed satisfactory reliabilities and factor structures for both scales. The DSM-IV-MR-J identified 2% of the participants as problem gamblers while SOGS-RA identified 2.7%, and problem gambling was more common among boys than girls. It was concluded that problem gambling among adolescents is an area of concern for the Icelandic community that needs to be further investigated.     

Preliminary Evaluation of a Coping Skills Training Program for Those with a Pathological-Gambling Partner

Individuals living with a pathological-gambling partner can experience significant psychological distress. In this report, we conduct a preliminary evaluation of a coping skills training program (CST) for this population. Twenty-three individuals experiencing stress from living with a pathological-gambling partner who was not in treatment were randomly assigned to either CST or a delayed treatment control (DTC) condition. CST consisted of ten, weekly individual sessions to teach more effective coping skills. At the end of the treatment/delay period, CST participants, relative to those in DTC, showed a large improvement in coping skillfulness that appeared to mediate a corresponding large significant reduction in depression and anxiety relative to DTC. Partner gambling during the period decreased in both conditions but did not differ between them, nor did partner help-seeking differ. CST shows promise as an effective treatment for individuals distressed as a result of a partner’s gambling problem. Larger, longer-term evaluations of the intervention, and comparison with alternate treatment models are needed.     

A Comment on the Utility of Prevalence Estimates of Pathological Gambling

The case is presented that researchers interested in policy aimed at treating the pathological gambler need to shift focus to improving the utility of prevalence estimates. It is argued that researchers supplement prevalence estimates with practical and well-defined measures of severity and other predictors and correlates of help-seeking. The dimension of severity is emphasized as one means of providing estimates that are relevant to policy makers when placed in the context of additional measures that improve their meaning and utility. Estimates may then be partitioned along these dimensions to ascertain the proportion of gamblers most likely to need or seek treatment for gambling-related disorders. The recommendations provided are subject to a number of possible objections and are presented in the interest of stimulating further discussion such as the distinction between symptom assessment and the measurement of severity.     

Brief Communications: Treating Problem Gamblers: A Residential Therapy Approach

The Gordon House Association (GHA) is the UK's only specialist and dedicated residential facility for problem gamblers. This paper describes the GHA therapeutic programme which is centred round a nine-month period of residency. Progression through the programme is described by overviewing each of the phases. These are initial assessment and five distinct phases comprising coping with today (Phase One), coping with yesterday (Phase Two), coping with change (Phase Three), coping with tomorrow (Phase Four), and coping on my own (Phase Five). These phases are themselves underpinned within the GHA core therapeutic approach which is also described.
