This article describes treatment of a female problem gambler using mindfulness-based cognitive therapy (MBCT). The treatment protocol was adapted for problem gamblers from the manualized MBCT intervention developed by Segal, Williams, and Teasdale. Gambling behavior and mindfulness practice were monitored using daily diary entries maintained by the participant. The Beck Anxiety Inventory, Beck Depression Inventory—II, and the Five Facet Mindfulness Questionnaire were administered at pretreatment, posttreatment, 4-week follow-up, and 10-week follow-up phases. The Client Satisfaction Questionnaire was also used to assess acceptability of the intervention. The participant abstained from gambling, and anxiety and depression scores significantly reduced to subclinical levels over the assessment period. Exploration of mindfulness facets revealed that MBCT for problem gambling (MBCT-PG) may be useful in promoting acceptance of distressing thoughts and emotions. However, the participant did not maintain an intensive mindfulness-meditation practice over the follow-up phase of the intervention. The clinical implications of this case study are discussed.

This article reviews the literature with respect to mindfulness and its potential for reducing the severity of problem gambling behaviour. Interest in the role of mindfulness as a treatment for problem gambling has gained the attention of researchers across Australia, the United States, and Canada. However, the literature is limited and current studies have severe methodological limitations. Despite this issue, investigations have revealed that dispositional mindfulness is related to less severe problem gambling outcomes and that psychological distress, overconfidence and risk willingness, myopic focus on reward and ego involvement may act as mediators in this relationship. Moreover, the literature indicates that the inverse relationship between dispositional mindfulness and psychological distress may be mediated by factors such as values clarification; emotional, cognitive, and behavioural flexibility; non-attachment; emotion dysregulation/distress intolerance; thought suppression; and rumination. This article discusses the theoretical and clinical implications of these relationships with respect to mindfulness-based interventions for problem gambling. It is recommended that the approach be considered with cautious optimism.
