Gambling has been long recognized as an adult pastime characterized by thrills and risks. In recent years, however, it has increased significantly among adolescents, who have grown up in a society where it is legal and widely accepted. Movies, TV shows, and increased access to gaming through the Internet have helped embed gambling in modern youth culture. Although much youth gambling occurs off campus, school environments can unintentionally contribute to gambling behavior either through permissiveness or lack of awareness. Administrators can help reduce problem gambling by establishing clear policies and incorporating gambling into existing efforts to prevent risky or undesirable behavior. This article describes how schools can raise awareness and prevention of youth problem gambling and enumerates effective prevention models and prevention and intervention activities.
