OBJECTIVE
Computer/gaming station use is ubiquitous in the lives of youth today. Overuse is a concern, but it remains unclear whether problems arise from addictive patterns of use or simply excessive time spent on use. The goal of the present study was to evaluate computer/gaming station use in youth and to examine the relationship between amounts of use, addictive features of use and functional impairment.
METHOD
A total of 110 subjects (11 to 17 years of age) from local schools participated. Time spent on television, video gaming and non-gaming recreational computer activities was measured. Addictive features of computer/gaming station use were ascertained, along with emotional/behavioural functioning. Multiple linear regressions were used to understand how youth functioning varied with time of use and addictive features of use.
RESULTS
Mean (± SD) total screen time was 4.5±2.4 h/day. Addictive features of use were consistently correlated with functional impairment across multiple measures and informants, whereas time of use, after controlling for addiction, was not.
CONCLUSIONS
Youth are spending many hours each day in front of screens. In the absence of addictive features of computer/gaming station use, time spent is not correlated with problems; however, youth with addictive features of use show evidence of poor emotional/ behavioural functioning.
目的
如今，电脑/游戏站的使用在青少年生活中无处不在。过度使用令人担忧，但尚不清楚问题是源于成瘾性使用模式还是仅仅由于使用时间过长。本研究的目的是评估青少年对电脑/游戏站的使用情况，并考察使用量、使用的成瘾特征与功能损害之间的关系。
方法
共有110名来自当地学校的受试者（年龄在11至17岁之间）参与。测量了他们花在电视、电子游戏和非游戏类娱乐电脑活动上的时间。确定了电脑/游戏站使用的成瘾特征以及情绪/行为功能状况。采用多元线性回归来了解青少年的功能状况如何随使用时间和使用的成瘾特征而变化。
结果
平均（±标准差）总屏幕使用时间为4.5±2.4小时/天。在多项测量指标和信息提供者中，使用的成瘾特征始终与功能损害相关，而在控制成瘾因素后，使用时间与功能损害无关。
结论
青少年每天花很多时间在屏幕前。在没有电脑/游戏站使用成瘾特征的情况下，花费的时间与问题无关；然而，有使用成瘾特征的青少年表现出情绪/行为功能不佳的迹象。
