ABSTRACT Ways to clinically assess and treat problem gambling evolve as our knowledge about this disorder increases. This paper summarizes current knowledge about treating problem gambling and describes developments in the assessment, psychology, and biology of problem gambling that may be important for treatment.
We reviewed recent published literature reporting advances in the assessment, psychology, and biology of problem gambling. We retained for review only controlled clinical trials in which subjects were randomized to either psychological or pharmacologic treatment.
Although several gambling treatments were found to be efficacious, support for any specific treatment modality is still limited. Cognitive-behavioural treatments were most effective. Although diagnostic assessment has improved, there are still very few measures of gambling-related variables. The contribution to gambling of sex, concurrent psychiatric disorders, cognitive distortions, and impulsivity has been described. Evidence implicating decision-making areas of the cortex and disturbances in serotonin and dopamine functioning has been reviewed. Available evidence for a genetic contribution to problem gambling is weak.
Improvements in the methodology of gambling-treatment research were discussed to advance the clinical approach to this disorder. Developments in the area of assessment, psychology, and biology of gambling should inform clinical approaches to a greater degree than they currently do. We identified the need to study different types of gambling separately, rather than combining them, as an important goal.

Previous literature supported the relevance of this categorization (Potenza 2006; Toneatto and Millar 2004). "

    ABSTRACT: With the aim of validating the three pathways hypothesis of pathological gambling (Blaszczynski and Nower in Addiction 97:487-499, 2002) 372 pathological gamblers meeting DSM IV (2000) criteria were assessed via a structured clinical interview as well as being subjected to personality tests and evaluation of their gambling practices. Our results show that it is possible to identify three subgroups corresponding to the three pathways: behaviourally conditioned problem gamblers, emotionally vulnerable problem gamblers and antisocial impulsivist problem gamblers. Our results particularly demonstrate that impulsivist gamblers preferentially choose semi-skilful gambling (horse racing and sports gambling) whereas emotionally vulnerable gamblers are significantly more attracted to games of chance (one-armed bandits, scratch cards, etc.) This led us to propose a functional presentation of the three pathways model which differs somewhat from the Blaszczynski and Nower presentation.

    • "Recently, some empirical contributions have shown the validity of the metacognitive approach to the study of gambling (pathological gambling: Dowling et al. 2007; problem gambling: Toneatto and Millar 2004; non pathological gambling: Weatherly and Flannery- Woehl 2009). The metacognitive approach focuses specifically on the control of stimuli and cognitions associated with gambling, aiming at restructuring and/or strengthening coping skills, emotions and cognitions challenging the addictive behaviour, and preventing recurrence.

    ABSTRACT: The aim of this study was to explore the relations between gambling, brain emotion systems, personality, self/other perception, and hopelessness in an Italian community. Dimensions of gambling, positive and negative emotions, self/other perception, personality and hopelessness were assessed in a community sample of 235 adults aged 19-59 years. Two structural models were tested. We found a significant correlation between problem gambling and impulsivity, which in association with aggressivity and negative personality dimensions may help explain the psychopathology factor, i.e. a latent variable involving neurotic personality, hopelessness, high sensation seeking, low metacognitive responsiveness, and disorganized patterns of interpersonal relationships. These results contribute to develop a theoretical framework of gambling in relation with personality factors and provide a new approach for clinical intervention of problem gambling that relies on a solid multidimensional perspective.

    • "Cognitive-behavioral therapies (CBT) have occupied a prominent position in the treatment of PG over the last decade. They have demonstrated their efficacy (Breen et al. 2001; Lopez Viets and Miller 1997; Petry et al. 2006; Petry and Armentano 1999; Sharpe 2002; Tavares et al. 2003; Toneatto and Ladouceur 2003; Toneatto and Millar 2004), and focus on gambling-related beliefs, behaviors and emotions, which are thought to contribute to the onset and maintenance of gambling problems (Toneatto and Millar 2004).

    ABSTRACT: The Gambling Attitudes and Beliefs Survey (GABS) is a questionnaire which explores gambling-related dysfunctional beliefs in an unidimensional way. The present research aims to investigate the dimensionality of the scale. 343 undergraduate student gamblers and 75 pathological gamblers seeking treatment completed the GABS and the south oaks gambling screen. Exploratory and confirmatory factor analyses revealed that the original one-factor structure of the GABS did not fit the data effectively. We then proposed a shorter version of the GABS (GABS-23) with a new five-factor structure, which fitted with the data more efficiently. The comparisons between students (problem vs. non-problem gamblers) and pathological gamblers seeking treatment indicated that the GABS-23 can discriminate between problem and non-problem gamblers as efficiently as the original GABS. To ensure the validity and the stability of the new structure of the GABS-23, analyses were replicated in an independent sample that consisted of 628 gamblers (256 non problem gamblers, 169 problem gamblers who are not treatment-seeking and 203 problem gamblers seeking treatment). Analyses showed satisfactory results, and the multidimensional structure of the GABS-23 was then confirmed. The GABS-23 seems to be a valid and useful assessment tool for screening gambling-related beliefs, emotions and attitudes among problem and non-problem gamblers. Moreover, it presents the advantage of being shorter than the original GABS, and of screening irrational beliefs and attitudes about gambling in a multidimensional way. The five-factor model of the GABS-23 is discussed based on the theory of locus of control.
