A study of young online gamers showed that the prevalence of Internet gaming disorder in Taiwan is about 3.1 percent, slightly higher than many European countries and the US, National Health Research Institutes (NHRI) researchers said yesterday.
The WHO in June classified “gaming disorder” as a mental health condition in its International Classification of Diseases (ICD-11) — a list used by health professionals when making diagnoses and treatment plans.
Lin Yu-hsuan (林煜軒), a National Taiwan University Hospital psychiatrist and assistant research fellow at NHRI’s Institute of Population Health Sciences; Pan Yuan-chien (潘元健), a psychologist; and Chiu Yu-chuan (邱于峻), a psychiatrist at Mackay Memorial Hospital, discussed their study at a news conference at the Ministry of Health and Welfare in Taipei.
They asked mental health counselors at 169 schools, from elementary to senior-high, to conduct structured diagnostic interviews of 8,110 students aged between 10 and 18 who had played Internet games in the past year.
“We used a globally recognized system of diagnostic criteria for Internet gaming disorder, which has nine symptoms, and those who meet five or more symptoms are defined as having Internet gaming disorder,” Lin said. “These symptoms have to frequently occur and continue for over a span of one year.”
Children or adolescents who play for long hours during summer vacations, but not during the school year, were not identified as having the disorder, he said.
“We found that the prevalence of Internet gaming disorder in children and adolescents is about 3.1 percent,” Lin said.
That figure might surprise many people, because studies that used other criteria have suggested the prevalence of Internet gaming addition to be 20 to 30 percent, he said.
However, nearly all studies using diagnostic criteria established by the American Psychiatric Association in 2013 for Internet gaming disorder suggested the prevalence to be less than 5 percent, and that the core symptom is being focused on “gaming behavior leading to distress or significant impairment in daily life functioning,” rather than “spending too much time on gaming,” he said.
A large-scale study conducted last year in Germany, the UK and the US suggested that the prevalence is only about 1 percent, Lin said.
“Up to 71.5 percent of the students in our study do not even have one symptom,” he said, adding that many children and adolescents use Internet gaming as a method to relieve stress or negative emotions, but those who are “addicted” need to play more frequently to feel satisfied.
Up to 52 percent of those identified as addicted have spent money in the games and spend an average of 41 hours per week playing games, which is about twice the percentage of non-addicted players — 25 percent and 24 hours respectively, Lin said.
From a clinical perspective, the problem is not just that the games are addictive, but that the addicted youngsters usually have real life problems that lead them to seek escape online, the trio said.
The government and the public should encourage these youngsters to improve their health, rather than treat them as mentally ill, they said.
A magnitude 6.4 earthquake struck off the coast of Hualien County in eastern Taiwan at 7pm yesterday, the Central Weather Administration (CWA) said. The epicenter of the temblor was at sea, about 69.9km south of Hualien County Hall, at a depth of 30.9km, it said. There were no immediate reports of damage resulting from the quake. The earthquake’s intensity, which gauges the actual effect of a temblor, was highest in Taitung County’s Changbin Township (長濱), where it measured 5 on Taiwan’s seven-tier intensity scale. The quake also measured an intensity of 4 in Hualien, Nantou, Chiayi, Yunlin, Changhua and Miaoli counties, as well as
Taiwan is to have nine extended holidays next year, led by a nine-day Lunar New Year break, the Cabinet announced yesterday. The nine-day Lunar New Year holiday next year matches the length of this year’s holiday, which featured six extended holidays. The increase in extended holidays is due to the Act on the Implementation of Commemorative and Festival Holidays (紀念日及節日實施條例), which was passed early last month with support from the opposition Chinese Nationalist Party (KMT) and Taiwan People’s Party. Under the new act, the day before Lunar New Year’s Eve is also a national holiday, and Labor Day would no longer be limited
The first tropical storm of the year in the western North Pacific, Wutip (蝴蝶), has formed over the South China Sea and is expected to move toward Hainan Island off southern China, the Central Weather Administration (CWA) said today. The agency said a tropical depression over waters near the Paracel and Zhongsha islands strengthened into a tropical storm this morning. The storm had maximum sustained winds near its center of 64.8kph, with peak gusts reaching 90kph, it said. Winds at Beaufort scale level 7 — ranging from 50kph to 61.5kph — extended up to 80km from the center, it added. Forecaster Kuan Hsin-ping
COMMITMENTS: The company had a relatively low renewable ratio at 56 percent and did not have any goal to achieve 100 percent renewable energy, the report said Pegatron Corp ranked the lowest among five major final assembly suppliers in progressing toward Apple Inc’s commitment to be 100 percent carbon neutral by 2030, a Greenpeace East Asia report said yesterday. While Apple has set the goal of using 100 percent renewable energy across its entire business, supply chain and product lifecycle by 2030, carbon emissions from electronics manufacturing are rising globally due to increased energy consumption, it said. Given that carbon emissions from its supply chain accounted for more than half of its total emissions last year, Greenpeace East Asia evaluated the green transition performance of Apple’s five largest final
