Gambling is the betting or staking of something of value, with consciousness of risk and hope of gain, on the outcome of a game, contest, or uncertain event. The term is more broadly used to refer to games of chance, such as lottery or casino games, but it also includes some activities where skill can play a role, such as sports wagering.

It is a common activity that has many social, legal, and economic impacts. For most individuals, gambling is an enjoyable and occasionally addictive pastime, but for a small group, the habit can become serious and cause significant negative personal, family, and financial effects. Historically, gambling has been associated with crime, political corruption, and other harmful consequences for society.

For researchers studying the psychology of gambling, determining when an individual’s behavior crosses the line into pathological gambling is a challenging task. The terminology used to describe problem gamblers varies widely, and differs among research scientists, psychiatrists, other treatment care clinicians, and public policy makers. This reflects the fact that each of these groups has different paradigms or world views from which to view gambling and problem gambling.

For those who struggle with a gambling addiction, there are steps that can be taken to help overcome the urge. These include seeking out support from friends and family, trying to find new hobbies, and limiting spending on things other than necessary expenses. In severe cases, inpatient or residential treatment and rehabilitation programs may be needed to treat the disorder.
