To study the pattern of Internet use across people of various professions who have access to it; the impact of Internet use on their personal, social, and occupational life; and to evaluate their Internet use on the International Classification of Diseases-Tenth Revision (ICD-10) dependence criteria and Young's Internet Addiction Diagnostic Questionnaire (IADQ).
Hundred four respondents were assessed on a 31-items self-rated questionnaire covering all the ICD-10 criteria and Young's criteria for Internet addiction.
THE TYPICAL PROFILE OF AN INTERNET USER WAS AS FOLLOWS: the mean duration of Internet use was 73.43 months (SD 44.51), two-thirds (65.38%) of them were using Internet on a regular basis for a period of more than a year, the mean duration of daily Internet use was 39.13 months (SD 35.97), the average time spent in Internet use was 2.13 h (SD 1.98) everyday, more than half (56.73%) of the sample was using Internet at least for 2 h/day, and the most common purpose of Internet use was educational for two-thirds (62.5%) of the sample. The five most commonly endorsed items were as follows: the need to use the Internet everyday (53.8%), Internet use helping to overcome bad moods (50%), staying online longer than one originally intends to (43.3%), eating while surfing (24%), and physical activity going down since one has started using the Internet (22.1%). When evaluated on ICD-10 substance dependence criteria and Young's IADQ separately, the prevalence of the 'cases' of Internet addiction came out to be 51.9 and 3.8%, respectively.
The Internet affects the users' life in multiple ways. The sharp difference in the prevalence estimates of Internet addiction depending on the type of criteria used shows the fragility of the construct of Internet addiction. A cautious approach should be adopted while revising the nosological system to differentiate users from those who are dependent.
研究不同职业且能使用互联网人群的互联网使用模式；互联网使用对其个人、社交和职业生活的影响；并依据国际疾病分类第十版（ICD - 10）依赖标准和杨氏网络成瘾诊断问卷（IADQ）评估他们的互联网使用情况。
对104名受访者进行了一项包含31个项目的自评问卷评估，该问卷涵盖了所有ICD - 10标准和杨氏网络成瘾标准。
互联网用户的典型概况如下：互联网使用的平均时长为73.43个月（标准差44.51），其中三分之二（65.38%）的人定期使用互联网超过一年，每日互联网使用的平均时长为39.13个月（标准差35.97），每天花在互联网使用上的平均时间为2.13小时（标准差1.98），超过一半（56.73%）的样本每天使用互联网至少2小时，且互联网使用最常见的目的是学习，占样本的三分之二（62.5%）。最常认可的五项如下：每天需要使用互联网（53.8%）、互联网使用有助于克服不良情绪（50%）、上网时间比原计划长（43.3%）、上网时吃东西（24%）以及自开始使用互联网后身体活动减少（22.1%）。分别依据ICD - 10物质依赖标准和杨氏IADQ进行评估时，网络成瘾“病例”的患病率分别为51.9%和3.8%。
互联网在多个方面影响用户生活。依据所用标准类型，网络成瘾患病率估计值的显著差异表明网络成瘾这一概念的脆弱性。在修订疾病分类系统以区分使用者和依赖者时应采取谨慎态度。
