Gambling is a public health problem characterized by persistent and recurrent maladaptive patterns of gambling. There is a social incentive to reduce current gambling problems and prevent future gambling addiction. In this book, Chapter One begins with an analysis of the risk factors, prevalence, pathophysiology and discusses treatment options for pathological gambling. Chapter Two provides a review on the idea that games should be taxed in accordance to the revenue they generate from addicts, and more effective multidimensional prevention measures should be implemented. Chapter Three focuses on a desire-targeted intervention based on Naikan counseling for disordered gamblers (DING).
