The concept of “internet addiction” or “smartphone addiction” could be unfamiliar to some researchers. In South-East Asian countries, however, the adverse impact of internet or smartphone addiction has been taken seriously and has led to a series of studies and social work by the government and health care givers to curb and alleviate the problem. A recent study by the Korean Ministry of Gender Equality and Familyin 2013 reported that of the 1.63 million Korean adolescents, 17.9% comprised those with smartphone addiction.43 Moreover, over 24% of children diagnosed with internet addiction are hospitalized.44 A very similar trend is found in Japan. A study by the Japanese Ministry of Education has led to the recognition of the necessity for a government-managed system.45 Likewise, some specialized treatment centers and care-giving programs have been established in Europe (the outpatient clinic for behavior addictions in Mainz, Germany, and the Capio Nightingale Hospital in London, UK) and the USA (the inpatient centers RESTART internet addiction recovery program in Seattle, and digital detoxification and recovery center in Pennsylvania, USA).46 It implies that internet and smartphone addiction presents a significant global challenge.
