The essential feature of gambling disorder is persistent and recurrent maladaptive gambling behavior that results in psychosocial dysfunction. To make the Diagnostic and Statistical Manual, fifth edition (DSM-5) diagnosis of Gambling Disorder, an individual must endorse at least four of nine core symptoms during the same 12-month period. The majority of individuals with gambling disorder will not improve on their own, which underscores the need for evidence-based treatments. There are several treatment goals when treating someone with gambling disorder. First, the clinician needs to understand what the patient is expecting from treatment. Second, choosing the treatment that is best for the individual patient is another goal of treatment. An important consideration in treatment is to examine the genuine success of the actual treatment. As in all areas of clinical care, boundaries are important. This is all the more the case when treating individuals with gambling disorder.
