Abstract: Premature termination challenges the successful outcomes of psychological treatments for gambling disorder. To date, research has primarily identified clients who are at particular risk for dropping out of treatment. A smaller but growing body of literature has investigated when dropout occurs. Typically, those studies have not considered improvement in psychological distress within their operationalizations of dropout and therefore may have misrepresented when dropout occurs. The current study examined when dropout occurs using an operationalization based on the criteria of attaining reliable change in a naturalistic sample of clients with gambling disorder, and the classification rates yielded from that operationalization were compared to the rates from a more common operationalization. Participants (n = 334) were clients meeting diagnostic criteria for gambling disorder at an outpatient private practice who completed a measure of psychological distress at baseline and prior to each subsequent treatment session. A survival analysis was conducted to determine temporal patterns of treatment dropout (i.e., clients who discontinued treatment before realizing reliable changes in psychological distress) and completion (i.e., clients who discontinued treatment after realizing reliable changes in distress) at each treatment session. Forty-nine percent of clients were classified as dropouts, and the majority of those clients did so in the first few sessions. The more common operationalization of dropout classified clients as dropouts when they had improved in their distress and clients as completers when they had not improved in their distress. Discussion centers on the implications of dropout occurring at various stages of treatment and future directions.

Casino exclusion programs are intended to prevent or limit gambling-related harm. Although previous research showed that self-exclusion is associated with reduced gambling, it remains unknown whether self- and forced excluded subjects show different patterns of gambling behavior and if exclusion from casino gambling affects all gambling activities. The present study retrospectively investigated (1) the role of voluntariness of exclusion for the first time, and (2) general gambling behavior of excluded individuals before and after exclusion. A total of N = 215 casino excluders (self-excluders: n = 187, forced excluders: n = 28) completed an online survey or a face-to-face interview up to 8 years after enrollment. Self- and forced excluders showed similar rates of abstinence (self-excluders: 19.3%, forced excluders: 28.6%) and reduction (self-excluders: 67.4%, forced excluders: 60.7%), even though forced excluders reported a significantly greater initial gambling intensity compared to self-excluders (e.g., pre-exclusion gambling time; self-excluders: 3.2 days/week, forced excluders: 4.3 days/week). Overall, results indicated that 20.5% of excluders stopped all gambling activities and another 66.5% reduced their gambling. Those who continued gambling significantly reduced this behavior in every segment, except for gambling halls. Findings indicate that self- and forced exclusion are associated with similarly reduced gambling behavior, even in non-excluded segments. However, unchanged gambling in gambling halls emphasizes the importance to implement consistent exclusion programs over all gambling segments.

Abstract: This study aims to test the application of the incentive-sensitisation theory to slot-machine gambling behaviour. The theory posits that for problem gamblers (PGs), gambling strengthens the response of motivational pathways in the mid-brain to gambling cues, eliciting strong wanting, independent of liking. Non-problem gamblers (NPGs) experience weaker changes to motivational pathways so liking and wanting remain associated. Hence, it is predicted that wanting to gamble will be greater than liking for PGs but there will be no difference for NPGs; wanting will be greater for PGs than for NPGs; and, wanting but not liking will predict whether PGs continue gambling, whereas both will predict this for NPGs. During gambling on an online simulated slot-machine, 39 PGs and 87 NPGs rated “liking” and “wanting”. Participants played at least 3 blocks of 10–20 spins, and then had the option of playing up to 4 additional blocks; to continue playing they had to complete an effortful task, so that “number of blocks played” acted as an additional indirect measure of wanting. Results supported hypotheses except on the indirect measure of wanting (the number of blocks played).

Abstract: Objectives: Disordered gambling often co-occurs with psychiatric and substance use disorders. The study aim was to assess the healthcare costs of pathological gambling (PG) and co-occurring mental health and substance use disorders by payer. This is the first-of-its-kind economic analysis of addictive behaviors and mental health disorders.
Methods: Study data were derived from the Massachusetts All-Payer Claims Data-a representative health claims database-for the period 2009 to 2013. The study analytical sample contained all medical and pharmaceutical claims for commercially insured Massachusetts residents who were aged >=18 years, had health insurance coverage, had a diagnosis of PG, and sought care in the Commonwealth. Healthcare cost components included outpatient, inpatient, emergency room visits, and prescription drugs. Bootstrap analysis was performed to account for skewed distribution of cost data. All costs were adjusted to constant dollars.
Results: The study sample included 599 patients over the study period. The most prevalent principal diagnoses were disorders of impulse control (50%), episodic mood disorders (31%), anxiety disorders (14%), and psychoactive substance (9%). The mean annual total expenditures on health care per patient with diagnosis of pathological gambling were $7993 +/- $11,847 (bias-corrected 95% confidence interval) in 2009, $10,054 +/- $14,555 in 2010, $9093 +/- $13,422 in 2011, and $9523 +/- $14,505 in 2012. Pharmaceutical expenditures represented 16% to 22% of total healthcare expenditures. In the study period, prescription drug co-pays represented approximately 16% of the pharmaceutical expenditures.
Conclusions: Psychiatric comorbidity and substance use disorders, and nondependent abuse of drugs are highly prevalent among pathological gamblers. These disorders pose an economic burden to patients and healthcare payers.

Abstract: Traditionally, gambling and problem gambling research relies on cross-sectional and retrospective designs. This has compromised identification of temporal relationships and causal inference. To overcome these problems a new questionnaire, the Jonsson-Abbott Scale (JAS), was developed and used in a large, prospective, general population study, The Swedish Longitudinal Gambling Study (Swelogs). The JAS has 11 items and seeks to identify early indicators, examine relationships between indicators and assess their capacity to predict future problem progression. The aims of the study were to examine psychometric properties of the JAS (internal consistency and dimensionality) and predictive validity with respect to increased gambling risk and problem gambling onset. The results are based on repeated interviews with 3818 participants. The response rate from the initial baseline wave was 74 %. The original sample consisted of a random, stratified selection from the Swedish population register aged between 16 and 84. The results indicate an acceptable fit of a three-factor solution in a confirmatory factor analysis with “Over consumption”, “Gambling fallacies” and “Reinforcers” as factors. Reinforcers, Over consumption and Gambling fallacies were significant predictors of gambling risk potential and Gambling fallacies and Over consumption were significant predictors of problem gambling onset (incident cases) at 12 month follow up. When controlled for risk potential measured at baseline, the predictor Over consumption was not significant for gambling risk potential at follow up. For incident cases, Gambling fallacies and Over consumption remained significant when controlled for risk potential. Implications of the results for the development of problem gambling, early detection, prevention and future research are discussed.

Abstract: Disordered gamblers have phenotypical and pathological similarities to those with substance use disorders (SUD), including exaggerated automatic cognitive processing of motivationally salient gambling cues in the environment (i.e., attentional and approach bias). Cognitive bias modification (CBM) is a family of computerised interventions that have proved effective in successfully re-training these automatic cognitive biases in SUD. CBM interventions can, in principle, be administered online, thus showing potential of being a low-cost, low-threshold addition to conventional treatments. This paper presents the design of a pilot randomised controlled trial exploring the effectiveness of two web-based CBM interventions targeting attentional and approach bias towards gambling cues in a sample of Dutch and Belgian problematic and pathological gamblers.
