Over the past 30 years there has been a dramatic increase in the availability of convenient and legal gambling opportunities. Accompanying this proliferation of gambling is a growing understanding that between 5% and 9% of adults experience significant to severe problems due to their gambling activities. These problems have become a real health concern, with substantial costs to individuals, families, and communities.The objective of this book is to provide the clinician or graduate student with essential information about problem and pathological gambling. After placing this behavioral addiction and its co-occurring difficulties in perspective, by describing its proliferation, the associated costs, and diagnostic criteria and definitions, the authors present detailed information on a strategy to assess and treat gambling problems in an outpatient setting.
