网络成瘾大学生的感觉寻求水平及神经诱发电位特征

目的：比较网络成瘾大学生的感觉寻求差异、神经诱发电位特征，为探讨网络成瘾机制提供基础。方法：采用Young氏网络成瘾诊断问卷、感觉寻求问卷作为研究工具,对1 784名在校大学生进行问卷调查；选择网络成瘾与非成瘾志愿者各10名进行以90 dB的短纯音作为刺激检测其长潜伏期听觉诱发电位。结果：网络成瘾大学生占总人群的7％，男性网络成瘾者显著多于女性（P<0.05），年级间网络成瘾检出率差异无显著性（P>0.05）网络成瘾大学生在感觉寻求的去抑制因子和总分上高于非成瘾者（P<0.05）;网络成瘾者的N1波幅在Fz部位高于非成瘾者（P<0.05），网络成瘾与感觉寻求之间存在正相关关系（r＝0.340，P<0.01）。结论：网络成瘾者与非成瘾者的感觉寻求水平与神经诱发电位有关联，高校应该关注高感觉寻求者的精神生活，避免网络成瘾。

Sensation seeking and biological traits in internet addiction disorder and common students in college

Objective To investigate the psychological factors related to internet addiction disorder(IAD) in Chinese college students and compare the differences in sensation seeking and biological traits and basis between IAD and common students. Methods 1 784 college students were chosen randomly and interviewed with Sensation Seeking Scale and Questionnaire on IAD. Then ten IAD and ten no IAD were undergone long latency auditory evoked potential studies using tones at 90 dB SPL. Results There was significant difference between males and females(P<0.05),but none among grades. There were significant differences in sensation seeking total scores and Dis scores(P<0.05).N1 amplitude at Fz of IAD was more higher than that of no IAD(P<0.05).There was relationship between IAD and sensation seeking(r=0.340,P<0.01). Conclusion There are differences between IAD and common students in sensation seeking and biological traits and basis.The sensation seeker’s mental life should be paid more attention to avoid IAD.
