日前，我国首部《网络成瘾诊断标准》通过专家论证，玩游戏成瘾被正式纳入精神疾病诊断范畴。该诊断标准中明确指出网络成瘾患者临床症状的共同特点是：对网络存在强烈的沉迷和渴求，不断增加上网的时间和投入程度；停止或减少上网时出现烦躁、易怒等戒断反应；长时间人机交流，只愿意与在线朋友沟通等。

Feeling tense and angry because you cannot get online?

Time to seek medical help as Internet addiction¹ is now considered a clinical disorder² rather than a bad habit, a new Internet Addiction Disorder (IAD) diagnostic manual approved over the weekend by psychologists has shown.

Lingering online for more than six hours a day instead of working or studying and having adverse³ reactions from not being able to get online have been identified as two major symptoms of IAD.

Based on the report, sufferers usually engage in five main activities: Online gaming, Net pornography, excessive involvement in virtual social networking, too much Internet shopping and general cyber-surfing.

The manual would be the first of its kind in the world if the Ministry⁴ of Health officially approves it, said Tao Ran, a leading medical professional on addiction in China who also headed the drafting of the manual.

The ministry is highly likely to give the manual the green light next year, Tao said.

"If so, China will be the first country to recognize IAD as a clinical disease, like gambling⁵ or alcohol addiction," he told China Daily yesterday.

The manual could also influence how Western countries view IAD, he said.

The American Psychiatric Association is now debating whether to include IAD in the fifth edition of its Diagnostic and Statistical⁶ Manual of Mental Disorders⁷, the profession's primary resource of categorizing and diagnosing mental illnesses, due for publication in 2010, US media reported.

China has taken such a lead in the study of the affliction because of its rise in the country, Tao said.

About 10 percent of the country's 40 million underage Net users are addicted⁸ to the Web, a report released in August by the National People's Congress Standing⁹ Committee showed.

Research conducted by Internet media company InterActiveCorp last year also showed that 42 percent of Chinese youngsters polled felt "addicted" to the Web, while only 18 percents of Americans were said to have felt the same way.

The dependence¹¹ on the virtual world has also reportedly caused real-life problems. Tao quoted figures from the Beijing public security bureau as saying that 76 percent of juvenile¹² crime in the city is somehow Internet-related.

"We have more problems than the Western countries do in this area," Tao said.

But he also said IAD is a curable disease. Since 2005, the Military General Hospital of Beijing PLA, which Tao works for, has received more than 3,000 Internet addicts¹³. Up to 80 percent of them managed to rid themselves of the problem after three to six months of treatment, he said.

The treatment is similar to those for other addictions¹⁴: Cutting off patients' connection with the Web before offering them psychological counseling and complementing¹⁵ that with group interactive¹⁰ activities to teach patients how to socialize in real society.

Gao Wenbin, a researcher with the psychology¹⁶ institute of the Chinese Academy of Sciences, said the lack of family care, companions and real-life games are major reasons behind the rising number of young Net addicts in the country.

"Most children in China are the only ones in their families. They are told only to study hard, but no one really cares about their needs," Gao said.
