Problem gambling (or ludomania, but usually referred to as "gambling addiction") is an urge to gamble continuously despite harmful negative consequences or a desire to stop. Problem gambling is often defined by whether harm is experienced by the gambler or others, rather than by the gambler's behavior. Severe problem gambling may be diagnosed as clinical pathological gambling if the gambler meets certain criteria. Pathological gambling is a common disorder that is associated with both social and family costs. The ''DSM-5'' has re-classified the condition as an addictive disorder, with sufferers exhibiting many similarities to those who have substance addictions. The term ''gambling addiction'' has long been used in the recovery movement. Pathological gambling was long considered by the American Psychiatric Association to be an impulse control disorder rather than an addiction. However, data suggest a closer relationship between pathological gambling and substance use disorders than exists between PG and obsessive-compulsive disorder. == Definition == Research by governments in Australia led to a universal definition for that country which appears to be the only research-based definition not to use diagnostic criteria: "Problem gambling is characterized by many difficulties in limiting money and/or time spent on gambling which leads to adverse consequences for the gambler, others, or for the community." The University of Maryland Medical Center defines pathological gambling as "being unable to resist impulses to gamble, which can lead to severe personal or social consequences". Most other definitions of problem gambling can usually be simplified to any gambling that causes harm to the gambler or someone else in any way; however, these definitions are usually coupled with descriptions of the type of harm or the use of diagnostic criteria. The ''DSM-V'' has since reclassified pathological gambling as "gambling disorder" and has listed the disorder under substance-related and addictive disorders rather than impulse-control disorders. This is due to the symptomatology of the disorder resembling an addiction not dissimilar to that of substance-abuse. In order to be diagnosed, an individual must have at least four of the following symptoms in a 12-month period: *Needs to gamble with increasing amounts of money in order to achieve the desired excitement *Is restless or irritable when attempting to cut down or stop gambling *Has made repeated unsuccessful efforts to control, cut back, or stop gambling *Is often preoccupied with gambling (e.g., having persistent thoughts of reliving past gambling experiences, handicapping or planning the next venture, thinking of ways to get money with which to gamble) *Often gambles when feeling distressed (e.g., helpless, guilty, anxious, depressed) *After losing money gambling, often returns another day to get even (“chasing” one’s losses) *Lies to conceal the extent of involvement with gambling *Has jeopardized or lost a significant relationship, job, education or career opportunity because of gambling *Relies on others to provide money to relieve desperate financial situations caused by gambling 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Problem gambling」の詳細全文を読む スポンサード リンク
