Gambling is an underrecognized problem from both a clinical and a public health point of view. It is not uncommon for an adolescent or adult to participate in one form of gambling or another on a regular basis, be it the lottery, card playing for money, sports wagering, or gambling on electronic gaming devices. Nor is it uncommon for such participation to reach excessive or destructive proportions, with negative effects on the individuals psychological, social, economic, and family life. The results of the National Research Councils 2000 review of empirical studies suggest that 85% of adolescents report having gambled during their lifetime, with 73% of adolescents reporting having gambled in the past year. Despite gains in knowledge concerning the correlates and risk factors associated with severe gambling problems among youth during the past ten years, a general lack of public and parental awareness exists. This raises serious mental health and public policy concerns. Written from an international perspective, this book covers gambling research and interventions in the following categories: role of helpline services; a Jungian-transpersonal approach to treatment; cognitive therapy for problem gambling; pharmacological interventions for problem gambling; desensitization/biofeedback as treatment for problem gambling; binge gambling; pathological gambling; past and contemporary aboriginal peoples experiences with gambling; problem-gambling counselor certification; measurement of outcomes in problem gambling treatment; overview of teen gambling-related issues from leading researchers.
