Gambling is an activity in which people risk money or other materials that have value on the outcome of events that are determined at least in part by chance. It can involve any type of game with an element of uncertainty, from traditional casino games to fantasy sports and daily fantasy football. People who gamble can win prizes or cash. Many people who gamble do not have a gambling disorder. However, some people have a serious gambling problem that can lead to other problems such as family or financial problems. This is called pathological gambling or compulsive gambling and may require treatment.
The term ‘gambling’ is often used in place of “betting” and it can be difficult to distinguish between the two. Many forms of gambling are legal in the United States, including lottery, bingo, scratchcards and betting on sports events. Whether these activities are considered gambling depends on the rules of each state. It also depends on how much money or other items are at stake.
It is estimated that 2.5 million U.S adults (about 1%) meet the criteria for a severe gambling problem in a given year. An additional 5-8 million people (2-3%) would be classified as having mild or moderate gambling problems. The definition of ‘problem gambling’ is very broad and includes not just losing control of the amount of money spent, but other consequences such as loss of income or relationships, as well as a negative impact on health.
Problem gambling can affect people of all ages, but it is more common in men than in women. It can start in early adulthood and continue throughout life. Some people may develop a gambling problem in response to other psychological or social problems such as anxiety or depression. It can also be triggered by specific events, such as the death of a loved one.
People who have a gambling disorder may find it hard to recognize their problem or seek help because they do not understand what is wrong with their behaviour. They might also feel ashamed or guilty about their gambling. They might also have beliefs about gambling that are shared by their community, which can influence their views of what is acceptable or not.
Some people may be genetically predisposed to gambling behavior. Research has shown that certain genes affect how the brain processes reward information and makes decisions. This may contribute to impulsivity and the ability to weigh risks.
It is important that scientifically based knowledge of gambling disorders is obtained through empirical studies. Contemporary scientists stand on the shoulders of pioneers who have done the early research, usually without institutional support. It is vital that a similar program of rigorous research is supported now to establish construct validity for the diagnosis of pathological gambling. Until this can be achieved, the psychiatric field cannot move forward in its understanding of the nature and effects of gambling disorders. It is crucial that the right balance is struck between clinical descriptive studies and etiological investigations.
