Veterans are at high risk of developing gambling disorder (GD). Mindfulness interventions can help treat GD in the general population, but they have not been tested on veterans specifically. This paper reviews a case series study of three veterans with GD who received Mindfulness-Based Relapse Prevention (MBRP). Overall, the participants reported gambling less often and craving gambling less often after the intervention. They also showed improvements in mindfulness, impulsive tendency, and emotion regulation. So, MBRP may be an effective treatment for veterans with GD. However, larger studies are needed to fully demonstrate whether it is effective.
